Before getting into the types of human-computer interface (HCI), let us look into the basics of the human-computer interface.

 

What is the human-computer interface (HCI) ?

There are several kinds of research going on, to study and to develop the interaction between humans and machines.

These researches will come under the term of HCI.

It is particularly aimed at making the communication between the computer and human easier.

While many devices in the present world are considered to be compatible with humans, there is still a long way to go in achieving the goals completely.

There is still a huge scope in the human-computer interface (HCI) where the interactions can be made simple and easy without the involvement of complex commands or codes.

 

Types of Human-Computer Interface (HCI) 

There are several principles and guidelines that must be followed in order to make communication between computers and humans possible.

This interface will vary on the type of method used.

There are several methods involved here among which the primary ones will include the following.

 

The Interface based on System:

One of the methods of human-computer interface is with the help of a system.

This method will include the way the system communicates to the user.

There are several commands and processes which are exchanged between a user and a system.

So, the interaction with the system will be documented here.

Since there are multiple approaches to a program, considering the interface based on a system will help in identifying the various angles of a program.

This will also help in analyzing any issues which might occur in the future.

 

The Interface based on User:

The main object in the human-computer interface is the human.

It is important to analyze and go by the user interface model as it will help in giving the review on how it works at the user level.

To make a program or application successful, the user side of the application should be of quality design, otherwise the application might not be welcomed as well.

To improve the design or the implementation part, it is ideal to go by the user interface type.

There are several approaches to this particular type of interface.

Ultimately, it all depends on how the program is designed to work in a real life situation and not just on paper.

While there are several approaches here, there is no one specific guideline since there are several users for a particular method, the approach will vary each time.

 

The Interface based on the Situation:

While the two most important parts of the human-computer interface are the user and the system itself, it does not necessarily stop there.

The situation for which the application is implemented might vary every time.

While the user and the system might remain constant, the environment will differ according to different situations. So the interface will have to be defined accordingly.

In this type of interface, the application will have to adjust according to the given surrounding or situation.

Only then the benefits of the application will be delivered completely.

 

The Interface based on Audio/Video:

The other important aspects and types of a human-computer interface will be involving the audio and video features.

This will dictate as to how the application will work.

The designing of the application will change to a great extent when the audio and video interaction is involved.

Since most of the applications in the future will have audio and video interface, it will play a major role in the application implementation.

While all these types are involved in human-computer interface, the way each one is involved will be different from one another. In fact, some of these are combined in several stages.

Windows is a widely used Operating System which is commonly used by a lot of people all over the world.

But sometimes you’ll run into errors while using the Windows OS.
Some of the error codes are

• S(0-499) (0x0-0x1f3)
• (500-999) (0x1f4-0x3e7)
• (1000-1299) (0x3e8-0x513)
• (1300-1699) (0x514-0x6a3)

Sometimes the Windows installer simply refuses to run or operate, leaving you unable to download any new games or programs.

Now, there are multiple reasons why you’re unable to install programs on your Windows.

In this article, we have discussed some things that you can do to fix this issue. Read this article carefully to learn the facts here now

 

Things to do when Windows installer doesn’t work

There are certain occasions in which the Windows installer stops running and shows an error report whenever you try to install a program.

This can be quite annoying. But there are a few general fixes that you can try yourself to fix this error. Take a look.

 

• Solution 1: Run as administrator

There are many programs and softwares out there, which require administrator privileges to be installed.

For safety reasons, the User Account Control (UAC) restricts your use to a limited account.

This is why you may see UAC pop-ups on your screen whenever you install a new program, asking your permission to install it.

The modern programs automatically ask for permission for installation.

However, once in a while a program may fail to install. In such cases, you can run the computer as an administrator and run the installer manually to complete program installation.

You can do so by right clicking on the installer file, followed by selecting Run as administrator.

Now agree to the prompt and the installer will write the file in system folders and install the program normally.

 

• Solution 2: Run the Fix It troubleshooting tool

Microsoft has a Fix It tool for troubleshooting purposes.

You can take the help of this tool to run the programs, which is otherwise not installing in the computer.

This tool detects corrupt registry keys and fixes them.

To use the tool, you can visit the official Microsoft page and click on Run Nowto use the tool.

It will repair all the corrupt keys and hopefully solve your problem.

 

• Solution 3: Uninstall older software version

In a few cases, you need to delete the older versions of a program before installing the new versions.

To install the new version of the program, you have to completely remove the older program along with its related components.

To uninstall the program, go to control panel and uninstall the program.

Now, by simply uninstalling the program, it might not remove it completely.

You can take the help of online tutorials to remove a specific program completely.

A third party installer can also help remove the residual junk files, although uninstalling programs from the control panel is the best way to remove it completely.

 

• Solution 4: Check for virus and malware

If a program is malicious or corrupted, it may fail to install.

Sometimes, antivirus software wont show pop-ups if it is kept in the silent mode and it will prevent the software from installing.

To fix the issue, disable the silent mode of antivirus and review the virus detection log to check if the file is malicious in nature.

Wrapping it Up

Not being able to download a program can be quite annoying, especially if you really wanted to install the programs for a long time.

Hopefully, the fixes mentioned in the article will help you solve the issue.

If none these works, then you can seek help from a professional who will fix the issue for you.

What is Natural Language Processing?

Natural language processing (NLP) is a component of artificial intelligence which supports the computers to understand the human language.

Natural language processing in a layman’s term means the technique which is used in AI and machine learning to help the system to understand and respond to the human language like a real human would do.

With a combination of computational linguistics and the field of computer science, this technology is brought into place.

This is achieved in order to close the gap between the processing of computers and human communication.

 

Use Cases of NLP

Think of the natural language processing in google search engine for example, you make voice search by speaking to your phone and the related answers are provided.

You only experience some symptoms but when you type how you experience it, google is able to interpret your query and tell you the actual illness or disorder.

Think of the article spinners and Google Translate app that you use to translate articles from one language to the other.

What about chatbots in customer relation services. All these are examples and use cases of NLP.

 

Where did NLP starts from?

The need for the communication gap to be filled between the humans and the computers has led this field to grow very fast.

This was possible with the support of big data and the available algorithms.

While humans communicate with the help of several languages, these languages cannot be interpreted by computers because the systems only understand machine language.

The processing happens with the crunching of the several zeros and ones in the system.

This, of course, leads to some possible errors.

The algorithms in place now help the systems to communicate in human form (in the case of digital assistants) where particular algorithms are even served for each user when there is a repetition in a given task.

There are voice-activated devices which will listen to the command given by the user and execute the command within seconds.

This is possible with the help of natural language processing which is combined with machine learning.

 

How does Natural Language Processing works?

There are several techniques which are used for interpreting the human language.

This is done with the help of combining ML and algorithm techniques.

Since the applications of natural language processing seem to happen in varied fields, there is a need for a variety of approaches based out of natural language processing.

There are some basic tasks which are handled with the help of natural language processing like speech recognition, language recognition, tokenization etc.

The implication of natural language processing is seen primarily in the case of the voice-activated virtual assistants.

Other than that this practice is used in the processing of emails, where similar format in spam emails is analyzed and notified to the user.

In the case of the mobile phones, there is the voice-based notification for missed calls which is possible with natural language processing.

It is also used in the content categorization when a user tries to enter text in the search bar of a website.

In the case of Telecom, NLP can be used in billing the customers.

All these are made possible by breaking down the language into smaller bits. Then these bits are analyzed and understood after which the tasks are processed.

 

Natural Language Processing Application

NLP can be used to search and arrange a given content based on the index for a language based document.

This document can be sets of data present on a website too.

It will also notify in case there is any duplication of the data.

The meaning of the content can be interpreted by natural language processing to which the advanced analytical techniques can be added to even make a forecast of the data.

The basic extraction of the inputted data can be done in seconds with this technique.

There is also the possibility to do sentiment analysis with a specific set of data by combining it with opinion mining.

Commands from the user can be taken by the system and then it can be translated into the machine language after which the given command can be executed.

While the conversion of languages used by humans to machine languages is possible on one side, the translation between the several languages used by humans can also be done here.

There are Natural language processing use cases in healthcare industry, where patients’ health education can be improved, individual patient’s needs are understood and the best approach to improving quality health care.

Example of use cases of NLP in banking and finance is in data analytics and customer relations where it is used to improve customer’s experience.

Complaint of individual client in the bank can be analysed in order to provide personalized service as much as possible.

Natural language processing is already transforming the retail banking and the future trend holds much improvement.

 

The need for natural language processing

Since the data keeps on growing along with the complications of the several language diversities in humans, the natural language processing is needed to convert these languages and then interpret it accordingly.

Since most of this data is in the unstructured, these systems are needed to analyze the huge set of data and to process it efficiently.

While every language used by humans is different, there is still a lot of complications attached to these languages in terms of grammar and accents.

All it requires is a semantic understanding for analyzing and interpreting the data and to provide a structure to it especially in terms of speech recognition.

While there are several benefits of natural language processing, the main limitation here is the issue of quality and accuracy in machine translation.

However, this can be more enhanced in the future and the pros definitely outweigh the cons.

What is Virtualization?

Virtualization has been in use for a long time now, but the term is getting popular only in recent years.

This can be because of the technologies which come under it, such as cloud computing, virtual data centers etc.

In this technology, there are platforms created which exist virtually. These platforms will help in connecting the systems of a computer or a network with the virtual systems.

The platforms are also ran by software which is specifically designed for virtualization.

 

The Types of Virtualization

There are several types of virtualization in cloud computing, which depends on the resources used.

 

Virtualization based on the Network

There are several resources which are part of a network. This starts from the basic IPs to even Routers present in the network.

With the help of network virtualization, all these resources can be connected virtually.

There will be no need for any kind of physical resources here.

If the platform is connected to one system, then the internal network will be preferred.

If there are several other resources connected to the network, then the external virtualization type of network will be implemented.

 

Hardware/Software Virtualization

There are systems which operate on two different operating systems.

With the help of virtualization, a system with existing operating software can be used to form a virtual system which has totally different operating software.

These two operating systems will be running separately and simultaneously.

In the virtual system, there is the new operating system which will be carrying out tasks using the primary system as host.

 

User Virtualization

There are several types of data present in a computer or a system. This data can be attained with this virtual network.

The system in which the data are present can be gained access and operated on even if the person is not physically present in front of the system.

With this option, the data in the system can be accessed and altered as needed. It gives the user the power of a personalized virtual desktop wherever they are.

In fact, the data virtualization technique applies to other gadgets like tablets and cell phones too.

 

Desktop Virtualization

Desktop Virtualization is similar to user virtualization. But as opposed to the user virtualization there is no personalized virtual desktop here.

Instead, the users are given the virtual access to operate on any of the devices such as personal computer, tablets, smartphones etc.

This virtualization platform is highly useful when it comes to corporate use and for tasks which are deadline-oriented and multi-location based.

Due to the various uses it holds, this virtualization network is immensely popular in the business world.

 

Memory Virtualization

There are huge chunks of data which is present in every system and in every server.

This data is stored in physical memory. With the help of virtualization, all the physical data present in various servers are connected to form the virtual memory.

This virtual memory can be designed and used for specific applications.

There are also options to use this virtual memory for accessing operating systems. It depends on the purpose for which the technology is used for.

 

Storage Virtualization

There are several servers present in a network. All these servers hold or store data.

This storage of all the individual servers can be combined to give a virtual storage system which acts as a network.

Some of the servers in the storage will need to have the required software for permitting access.

For the drive level use, the existing controls can simply be changed and the storage can be accessed.

Virtual Reality (VR) will change the way we interact with our environment if not create major transformations in all the industries.

While the pace of growth might just start with only a headset and seems slow now, the future impacts of VR would definitely be much more.

There are several benefits of virtual reality in businesses, health, gaming, transportation now.

In business, which is our concern here, VR is now much relevant especially in business training, marketing, management, and the economy at large.

There is a long way to grow in the field of virtual reality where customers can be taken to a whole new virtual world with this innovative technology.

 

Challenges & Future Prospect of VR

There are some challenges and concerns as of now, which include the cost of VR, comfort factor, lack of engaging content and the stress of wearing huge devices for a long time.

These are some potential problems with using virtual reality technology and it indicates that there are many more changes to be done in the hardware as well as the software front which will make VR tech more enticing.

But on the other hand, tech-savvy entrepreneurs are all the more excited about this innovative stream.

They are working constantly on producing new VR content for th future development which will increase the ease of use too.

Since many industries like education, health, gaming, among others are already benefiting from the VR based applications, they are expected to stay for long.

Technology experts predict that VR in the future will bring in a whole new perspective and will be able to give a real-life experience in the digital world, have positive effects on the society and the economy.

They believe that the next major sector will be the one involving VR.

 

The Techniques behind Virtual Reality

While the usual 3D space will only provide a display to watch, the virtual reality technology will act as an interface where the person will get to fully experience the enhanced 3D virtual world.

All senses, including the sight, hearing and touch will be utilized as a stimulus in order to experience the artificially produced virtual environment.

This will involve the source from where the content is originated and also a device which will be utilized by the user.

As of now, the user devices vary from headsets, goggles, gloves to even virtual treadmills.

When the content is combined with the user device, a high-quality virtual image is produced which will be interactive.

The virtual world will be realistic depending on the components like the motion delay, view, pixel quality, image quality, audio, and video synchronization, refresh rate etc.

Since the human vision will act as a video frame, tricking the mind into thinking that the virtual environment is real, is quite difficult.

Added to this is the peripheral vision which limits the visual world experience.

This will definitely have positive impacts in neuroscience, surgical operations, travelling and transportation.

VR will not only help in business but in better and healthier lifestyle of the people in the society and improving the economy through the productions of these VR techs and support services around this technology.

 

The Virtual Reality Process

To produce a VR environment, there are devices like the headset and a mobile device which should be present.

In some situations, a motion tracking device will also be needed.

What happens is that the headset in front of the eyes will display the content.

A cable will be used to transform the image from to the screen from a mobile device or a computer.

There are also devices which have both the source content for VR as well as the display like the ones developed by Google.

The images can be made 3D by opting for the particular lens. The frame rate per second is maintained at 60 fps in order to bring out a virtual reality environment.

This rate can be increased to enhance the experience. For tracking purposes apart from the mentioned motion tracking, there are also head and eye tracking systems in place.

In the case of head tracking the headsets are based on the movement of the head to the different sides and angles.

With the combination of a number of tools and with directions the end result is achieved.

There are certain cases where the users will witness the time gap between the movement and the simulated image which can be avoided with the proper latency.

There are headsets which come with the infrared controller. This will also allow the tracking of the eye movement.

Compared to head tracking, this method will produce a deeper engagement with the user.

While these are the basic steps in tracking, motion tracking is the one which will take the system to the next level.

However, it is still in the development stage.

With concepts like optical and non-optical tracking, free fall, 3D space this tracking stream is yet to be explored a lot.

To connect your PC to WiFi network, uually you just have to choose the router and then enter the respective password for it and get connected to the Wi-Fi.

But in the case of switching on 5 GHz WiFi on your computer, the process is a little more complicated.

To begin with, first, you should be aware if your router will support 5GHz.

There are several cases where one might be breaking one’s head as to why the Wi-Fi is not getting enabled after trying out all the steps.

The reason might be simple, that the router might not support it. So, check with the instruction manuals that come with the router, or try logging in to the router and check in the settings tab.

Go to the my Devices page and select your 5G Home Router, do the performance test and select Measure Signal Strength to know if your router is compatible.

Start the test and once it’s completed, you’d see the signal strength for each device connected to the 5ghz Router.

 

Do your Wi-Fi standards go with 5 GHz?

After that, the next important step is to check your Wi-Fi standards as there are specific standards which will work on 5GHz.

Usually, all the 802.11ac, 802.11a, and 802.11n will support them.

In some 802.11n models, the preferred one is 2.4GHz. So if you have 802.11n, then you need to check if 5GHz will go with it.

There are routers which will not support both the frequencies at one given point of time.

Due to this fact, you might not be able to use the 5GHz. To avoid this, make sure all the devices in your Wi-Fi will support the 5GHz.

But in the case of dual-band routers, this will not be a problem. This is because the dual-band routers have the ability to run both radios at the same point of time.

There is a chance that the difference in frequencies might still affect the communication as at times, different frequencies will not be supported properly.

This problem is consistent when different devices of variable frequencies are connected to the same router.

In order to enable the 5GHz on your Wi-Fi after checking the requirements, you will have to follow the given procedure.

 

5GHz with Router and wireless adapter

As mentioned earlier, you will have to first check out if the model of your router will go with the 5GHz.

You can identify it by looking at the model itself. By going through the specific manufacturer’s site of the router you will be able to find out all about the router and the frequencies it will support.

Usually, if the router will support the 5GHz then it will be mentioned in the box.

In case you are not able to find it in the box, check for the terms under the ‘support’ option.

If it is mentioned that the adaptor will support 802.11a 5GHz then there is no research needed here.

Some adapters will have the terms given as ‘supports 802.11g 2.4GHz’. There are others which will support 802.11b 2.4GHz.

Then there are adaptors which will support both the 802.11n 2.4GHz as well as the 5GHz, but it might not be true for all cases.

There are other sets of adaptors which support 802.11c 5GHz.

 

Which Home Routers Will Support 5GHz

Routers which have the 802.11a/g/n and the 802.11ac will support the 5GHz.

Looking into the router with 802.11b/g/n there are chances that it might not work in which case the router will have to be updated.

Once you confirm that the router falls under this category and will support the 5GHz connection then the adapter has to be checked.

This can be done by checking the device manager. Device Manager can be opened by simply searching it in the search tab in the system.

The result will be a list of drivers. Now the Network Adapters under the device manager should be opened where your wireless adapter can be spotted.

Now check for the details regarding the radio band which is supported.

If there are no details regarding it, then try searching for this detail online on the manufacturer’s site.

In case the details about the radio band are mentioned then the issue might be with the hardware.

In this case the adapter on the computer will have to be replaced with a one which supports the 5GHz.

 

How to Enable 5GHz in the Device Manager’s Settings 

Once you confirm that the hardware or the router is compatible with the 5GHz frequency, then there are chances that it might be disabled in the settings.

This can be changed easily. The first thing to do is to go to the device manager.

Then search for the wireless adapter under it.

Next, you will have to go to the properties bar which can be done by just right-clicking the wireless adapter option.

In the Advanced tab under the properties, go to the 802.11n mode. Click on the enable option and click ok.

Once you successfully complete this step then restart your computer in order to apply the changed settings.

This will show the 5GHz network in the Wi-Fi.

To avoid difficulties in this, apply some thought before buying your Wi-Fi adapter to make sure it runs at the said frequency.

Since, if the hardware is not compatible then the only option will be to change it.

As the migration to the cloud continues, cybersecurity is becoming all the more important.

According to Gartner, an industry leader in technology research, most information technology (IT) outsourcing deals will be influenced by cloud-adoption strategies by 2020.

Whether you are outsourcing your IT practices or performing them in-house, cloud security must be a top priority. Here is a look at the top three cloud security risks you need to fix ASAP.

Data Breaches

The cloud brings a plethora of benefits to your overall operations, including enhanced collaboration capabilities and reduced overhead expenses.

However, data breaches are continuing to become huge security risks. In 2017, the Equifax data breach impacted more than 143 million people, making it clear that no matter how large or small a company might be, no one is immune to a potential data breach.

In fact, in 2017 alone, more than 1.4 billion records were compromised due to data breaches. 

To protect your company, have a cybersecurity specialist assess its IT infrastructure.

In addition, keep all business and personal accounts separate from each other.

Most importantly, employees need to be properly trained on how to avoid data breaches.

 

Internal Threats

Most companies underestimate the possibility of internal threats to cloud security such as leaked passwords and confidential data — be it malicious or simple human error.

While most employees can be trusted, a single rogue staff member who has even a minimal amount of cloud-hacking knowledge can carry out a cyber attack that brings down the entire IT infrastructure.

Fortunately, daily monitoring of cloud usage can easily deter internal threats.

Keep in mind that the person responsible for performing daily monitoring should be monitored, as well. Ideally, you’ll want to outsource cloud monitoring to make sure internal hacking and abuse aren’t taking place.

 

Update All Custom Applications

Creating custom apps can bring your company a new level of success, especially in regard to efficiency and superior customer experience. Unfortunately, it also brings a new level of security risks.

Application programming interfaces (APIs) are crucial to cloud security, and they must be updated to ensure they are not vulnerable to cyber attackers.

In a sense, APIs are a front door to your custom apps. If they aren’t secured properly with a deadbolt (i.e., regular updating), they’re left wide open to attacks.

Your customers are constantly using APIs to interact with your cloud applications.

In addition to regular monitoring, you should practice provisioning to keep cloud security risks to a minimum.

Not only can malicious attacks occur if the APIs aren’t updated regularly and protected properly, but accidental breaches can occur as well, exposing confidential and valuable information to the public, the hackers, or both.

To create policies that protect APIs, mimic the best security practices of industry leaders such as Amazon Web Services.

These three cloud security risks are only a few of the ones you need to prioritize. They’re a good starting point, however, for making sure your cloud environment is protected from breaches and hackers.

 

Do you know that your PC might be infected with a malware or virus already? It doesn’t matter if the computer is new or old, connected to Private or publish Internet network or even used offline only.

 

There are several ways your PC can be infected with virus and there are different forms of computer viruses that can alter the normal functioning of your system, break it down completely or steal your private data.

 

We’ll briefly cover how you can remove malware, Trojan from your laptop computer using Windows irrespective of versions, whether old one like Windows 7 or others like 10 and remove them free manually or using antivirus program.

 

There are certain ways that your PC begins to act when it’s been infected by a virus. Some of the symptoms of an infected computer are the following but not limited to these:

 

1.Your computer or/and Internet network starts slowing down

2. Strange images or sounds 

3. Your PC suddenly freezes 

4. Pop-up messages and ads

5. The Internet traffic suddenly increases

6. Your browser homepage changed without your input

7.  Sudden and continuous connections to strange websites

8. Security program is disabled

9. Automatic sent message you’ve not initiated in your email account

10. Unfamiliar icons are displayed on your desktop

11. Unusual error messages

12. PC Control Panel is not accessible

13. Loss of files or getting additional files

14. Problem printing files

 

Sometimes, in rare cases, your computer can be working normal even when it’s infected by virus, however, if you notice any of the signs above, it may be time to find out if your system probably has a malware or virus attack.

 

With countless types of malware and several different system setups we have today, we can’t possibly cover everything here but we will point out the basic steps that are sure to help you remove malwares or viruses from your windows PC and get your system back to normal.

 

Scanning Your Laptop With an Antivirus program

Some PCs those days come with an antivirus already, most notable is the Windows Defender for Windows 10.

If an antivirus application is installed on your system, you’ll still have to be updating once the developer releases a new version of the program.

 

If your computer didn’t come preinstalled, you can still download spyware & malware removal app to help detect viruses.

 

Once you’ve it, run  an in-depth system scan, after the scan has been completed, your antivirus software should spot the problem and effectively remove it on its own.

If this is done successfully, your PC Would be free of virus and come back to work normal.

Unfortunately, if your antivirus program doesn’t detect anything, you’d have to dig a little deeper with the next step.

 

Booting your PC into Safe Mode & Deleting Temporary Files

Boot into Safe Mode by restarting your PC. Immediately your system comes back up, start pressing “F8” continuously. If it’s done successfully, you’d see a list of options displayed for you to choose from.

 

Scroll to “Safe Mode with Networking” and choose by hitting enter to boot. Now you’re in Safe Mode, the next thing for you to do is to erase Temporary files in your computer by using an accessory that comes with your PC called “Disk Cleanup Tool”. 

 

The reason for doing this is to help with your next step which is “scanning your computer”. Deleting temporary files can also help get rid of the malware if it was set or programmed to load when your PC boots.

 

Running a Scan With an On-demand Malware Scanner

Download Malwarebytes (an on-demand scanner) on the infected computer, open and follow instructions for a complete scan. After the scan, click on scan result to view the spotted infections, select them and remove them. After you’ve successfully removed them, restart your PC and that’s all.

 

Always remember to keep your PC safe by enhancing your security. Update your antivirus, avoid downloading from untrusted websites, and make sure to keep your Windows updated.
