5G virtual reality at the service of patients with multiple sclerosis

Published

on

The application of virtual reality techniques to treat or alleviate certain diseases has been studied for a long time. It has been proven to create environments to confront some phobias safely or to stimulate the cognitive part in certain patients. In the case of the treatment of multiple sclerosis, there are also projects aimed at complementing the rehabilitation of patients.

Multiple sclerosis is a disease of the nervous system, which affects the brain and spinal cord. Its causes are not exactly known, although it is known to be linked to genetic, environmental, and infectious factors. It is chronic and, over the years, we have learned that one of the most effective ways to slow down its development and maintain or improve the patient’s quality of life is rehabilitation. It is used in combination with drugs to slow the progression of the disease.

The use of virtual reality, to alleviate this and other ailments, will gain adoption with the arrival of 5G. And it is that one of the main disadvantages of this technology is having cables connected to the glasses. There are already models that have got rid of these ties, but many times there is a signal delay, due to the connection. The new mobile telecommunications network will avoid this extreme, as it guarantees a much lower latency, between 1-5 milliseconds.

Virtual reality to motivate the patient

One of the problems that physiotherapists encounter is the so-called adherence to rehabilitation. As it is a chronic task, the perseverance of any patient is put to the test. Sometimes the exercises have to be more intensive and other times, they are more maintenance. But they always spread out over time.

“ The virtual reality glasses bring, above all, novelty and motivation to the patient. Doing functional exercises in a rehabilitation environment and it chronically becomes repetitive ”, explains Laura García Ruano, coordinator of Physiotherapy Services at FEMM (Fundación Esclerosis Múltiple Madrid). “So including incentives in which the movements or activities are the same, but a totally new environment is introduced generates interest and increases attention. With this, we achieve adherence, that people do not lack ”.

Immersive environments

This novelty that virtual reality brings is achieved with the creation of attractive scenarios. Deploying them on the glasses requires a high-speed, low-latency connection. Otherwise, there may be lags or skips in the image, which will make the user dizzy. Hence, 5G is destined to become a suitable means to use this type of glasses.

For the treatment of multiple sclerosis, it is attractive for a patient to enter a different environment, such as the relaxing environment of a jetty or a medieval world, with beasts and beasts. “All this playful part increases motivation and also performance,” says García Ruano. It refers to the fact that raising your arm for the fact of having to do it, for pure rehabilitation, has much less interest for a person than doing it to eliminate a fantastic creature that assaults you. This part of gamification works to motivate.

Virtual reality as a treatment for multiple sclerosis

One of the doubts that remain is whether the patient will be able to use this type of glasses at home. “Since it can be done by the user as a complement to standard rehabilitation, it could even be done at home. Although in reality, since they need a large and clear space, so that if you deviate you do not crash into the road, I think that in the end, it will end up being done in rehabilitation units ”, reflects García Ruano.

In any case, it always has to be a complement to the usual rehabilitation that these people carry out. A more dynamic and fun extra. García Ruano points out another of the advantages of virtual reality: “It has a very good thing, which is that you can see the performance and the results. And, knowing the patient previously, you can, as a physiotherapist, program their exercises in a personalized way ”

The inalienable role of a professional

Although there must always be a professional involved in the treatment of multiple sclerosis, according to García Ruano. She, as a physiotherapist, sees what kind of exercises the patient has to do and, from there, can adapt the virtual reality program. Although, he points out that not all programs can be adapted to all patients.

The condition of multiple sclerosis is very varied. And, unlike a physio, which can be adapted to any patient, virtual reality is not without finite options. That is, it has the ability to act as a stimulating and motivational complement, but with the corresponding supervision. “It has to be something planned, programmed, and supervised by a professional, who in turn knows what the patient is like,” concludes García Ruano.

The physiotherapist also points out a type of patient. “There are people who tend to fail in everything, such as fatigue, balance … And it is also quite recurrent that they have visual and balance problems, at the level of dizziness, feelings of vertigo. And some of these screen elements add to that feeling. ” In these cases, obviously, the technology would not be applicable.

Running Games using Direct X Technologies

Published

on

Most Windows-based Operating Systems in today’s scenario use Direct X for accessing low-level hardware components to enhance the multimedia experience to users. Direct X is a series of APIs that facilitate this feature. As such, it is a vital component in Windows. Microsoft delivered DIRECT X to provide ease for developers in creating games and video rendering applications. Files like d3dx9_43.dll and d3dx9_41.dll establish a connection between the system application and the graphics card. In such instances, it is vital to understand the need for Direct X to run applications like games and video playback software. Thus, this article focuses on understanding what Direct X is and various aspects regarding this technology.

Direct X – A brief introduction

Direct X, often known as Direct X 3D, is a library that contains different APIs for the efficient operation of multimedia environments. These are examples. DLL files required for games and applications created using Microsoft Visual C++ and Microsoft Redistributable packages are libraries that facilitate this endeavour. In today’s world, most game developers make use of these when developing applications. As a result, Microsoft greatly assists developers in creating apps for their Operating Systems by offering outstanding libraries with different components critical to the operation of these programs.

What does Direct X do?

i) Establishes Link – The primary function of the Direct 3D technology is to establish a connection between the system application and the graphics processor. This feature facilitates the access of low-level hardware components to perform efficiently.

ii) Software Settings – Gone are the days where one manually updated configuration settings from batch files. Today, individuals using Windows-based Operating systems can change the settings on the user interface of the software. This feature is highly beneficial for individuals that are less technically empowered. As such, Direct X makes a thorough analysis of the system specifications and chooses optimal software settings to ensure the smooth performance of an application.

iii) Graphics Rendering – Another vital function of Direct X is to render graphics to a substantial extent. With the advent of improving technologies like graphic processors and system microchips, high-level rendering delivers surreal software. Big companies like Nvidia, AMD, etc., create exquisite graphic processors for systems. Direct X transfers a load of high-level processes to the GPU. By doing so, it relieves the primary processor of a lot of its duties. This feature highly enhances system performance.

Resolving Errors Related to Direct X

Various errors occur due to faulty installations of Direct X. As such, many users in today’s scenario face these errors. Here are some of the methods to resolve these errors.

i) Version Error – In a few instances, the error is trivial and easily solvable. The Direct X versions don’t satisfy the requirements of the software. As such, it is vital to ensure that the Direct X on one’s system is up-to-date. One can do so by using the “dxdiag” function offered by Windows.

ii) Reinstallation – One can also try solving these errors by reinstalling Direct X and graphics drivers. By doing so, they reset the entire configuration of the graphics processor resulting in loss of data.

iii) Download the file – In cases of corrupt or missing .dll files, one can always download these files. However, immense consideration has to be taken into account while downloading files on the internet with the advent of increasing cybercrimes.

In conclusion, Direct X technology has eased the process of developing games for Windows-based Operating systems. It also allows users with low specs to run such software. Files like d3dx9_43.dll often go missing due to various errors, as observed earlier. However, by understanding the elements in these libraries, one can resolve such issues with ease.

Know the Key Points That Outline the Prince 2® Framework

Published

on

PRINCE is the abbreviation for Projects in Controlled Environments. It was first invented in the UK as a step by the Government to try out new methodologies for project management. However, it soon gained vast popularity across the globe owing to its good results. AXELOS is the authority figure behind the PRINCE framework. This means that when you get the PRINCE 2 certification, it is the accreditation from AXELOS that will gain you recognition in any part of the world, wherever an organization is searching for PRINCE 2® experts to be hired. So gear yourself up, as we will take a deep dive into the key points of the PRINCE 2® framework in this article!

1.     Your Project Should Always Have a Business Justification –

Starting from the initial steps to the end results, according to the guidelines mentioned in the PRINCE2® foundation and practitioner course, every step of the project must always have a justification. There must be a factor of accountability present where the upper management must keep a check on where there is a good return on investment. Not only that, the risks of the object must be controlled, and the benefits must outweigh the setbacks of the project.

2.     Everyone Must Be Aware of Their Roles and Responsibilities –

An important aspect of the PRINCE 2® methodology is that every team member must be thoroughly aware of their roles. Not only that, but everyone must also know their responsibilities as a part of a team. This is in order to ensure that there are a few setbacks, confusion, and drastic delays as possible in the follow-up meetings. It is a common scenario in meetings to hear that “I thought Mr.X was responsible to take care of this task.” The PRINCE 2® certified project manager is responsible to look out for these scenarios.

3.     The Team Members Must Have a Controlled Focus but With a Little Room for Improvisation –

If you are working in a PRINCE 2® environment, you are expected to focus your full attention on meeting the requirements to achieve the end goal. But at the same time, you must maintain the quality of your work to the highest standard. However, the prince 2 methodology also leaves space for improvisation according to your specific work area-related requirements. If you are adopting the method, you must first identify which areas can be improvised in the methodology.

4.     The Team Must Always Keep on Evolving –

The PRINCE 2® methodology mentions a controlled environment, meaning that there must be a “lessons learned” log maintained by the team. This ensures that mistakes are avoided as much as possible. There must also be retrospective meetings where each member of the team gets to reflect on their overall performance.

Final Word

The PRINCE 2® methodology has different levels of qualification courses. This includes the PRINCE 2® Foundation course, the second one is the practitioner course. Make sure that you choose one according to your qualifications!

And it turned out that we were just stuck in the message then I tried to wait until it was finished but in the end it didn’t work, it just restarted  by itself. In addition to the error above after the restart process is  complete, you may start seeing some progress messages like this:

“Installing Updates 15% We couldn’t complete the updates, Undoing changes, Don’t turn off your –  computer Restarting” and I have good news that the process goes up again to 30% and the bad news is the computer restarts again and this will continue to occur if you do not make changes to your PC.

Cause of error We couldn’t complete the update, undoing changes

  • Windows Update can’t download smoothly. If the updates that Windows installed don’t download properly, this could cause an error to appear.
  • Insufficient hard disk space. In some cases, if you don’t have enough space for updates on your system volume, the problem could also be because of that.
  • The update was interrupted during installation. If the update is interrupted during the installation process like PC shuts down, etc. Errors can be caused by it.
  • System files are corrupted. Another factor causing this problem to appear is your corrupted system files.
  • There are applications, drivers etc that are not compatible with your PC. If indeed you have recently installed additional applications then it is highly recommended to delete them.

How to solve the error message We couldn’t complete the updates, undoing changes

    4. select vol (Select System Volume)
    5. act
    6. list vol
    7. select vol (Select System Reserved Volume)
    8. inactive
    9. exit

You can see the system volume and system reserved volume in the info and label section of cmd.

Configure BCD with the following code:

  1. bcdedit /set {bootmgr} device partition=C:
    2. bcdedit /set {default} device partition=C:
    3. bcdedit /set {default} osdevice partition=C:

Before making changes or rebooting , make sure you have Windows installation DVD or WinPE/WinRE Cd or USB flash Drive in case of Windows Boot failure. If Windows won’t boot, use the Windows installation disc to boot  which can be seen here: How to Make a WinPE Bootable USB .

After that, at the command prompt type the following code:

  1. bootrec /fixmbr
    2. bootrec /fixboot
    3. bootrec /rebuildbcd

After the reboot process , move WinRE from the system reserved partition to the system partition .

Now reopen the command prompt and type the code below and change the drive letter according to your partition letter which can be seen on diskpart.

  1. diskpart
    2. list vol
    3. select vol <Recovery Volume>
    4. assign let=R
    5. Disable WinRE:
    6. reagentc /disable
  1. Remove WinRE from the reserved partition with the code  rd R:Recovery .
  2. Copy WinRE to the system partition with the code  robocopy C:WindowsSystem32Recovery R:RecoveryWindowsRE WinRE.wim /copyall /dcopy:t .
  3. Configure WinRE :  reagentc /setreimage /path C:RecoveryWindowsRE .
  4. Finally enable WinRE :  reagentc /enable .
  5. For future use, create a new partition at the end of the drive (after the OS partition) and save the WinRE and OSI (Original System Installation) folder containing all the files contained in the Windows 10 DVD. Make sure you have enough free space on your hard disk to create this partition drive (usually 100GB). If you choose to create this partition, it is important that you set the partition ID flag to 27 (0x27) using Diskpart, which determines that it is the Recovery partition.

The final word

If nothing else works then Restore your PC to an earlier time ( restore point ), remove the problematic update from Control Panel, disable automatic updates and use your PC normally until Microsoft attempts to fix this update issue. In a few days, maybe 20-30 days, try to install the update again, if it still fails, please try the above method again. As for if you don’t want Windows updates and want Windows to return to normal then the most effective solution is to reinstall.

That’s about How to Overcome We couldn’t complete the updates, undoing changes in Windows 10, please ask if there are other problems in the comments section. Thank you..
