Here comes the question
How can a person with malfunctioning hands use and play the VR?
The answer is
to use the Adjustment of Controller Position and Range Boost option.
It changes the way a disabled person sees the controller in VR.
Players can adjust the controllers’ position and range of motion to compensate their limitations. This feature helps disabled people who are not able to move their controllers to the height or depth required by the video game..
Position adjustment makes virtual reality accessible when you cannot raise hands due to muscular dystrophies, spinal muscular atrophies, stroke etc.
You can adjust the default position for controllers in three dimensions:
It can also be used for training in VR for people with disabilities by gradually reducing the enhancements in controller positioning.
This feature means that disabled players can take full advantage of VR games and programs that require keeping their hands at the eye level or reaching high for objects.
Adjustment of controller range is useful when a person has limited range of movements. We can address it simply by translating small real movements to larger movements in Virtual Reality.
Players can adjust the sensitivity of the motion of the virtual reality controller, which is based on the physical controller. 3-inch real controller move can translate into 12-inch move in virtual reality.
Slight movements will actually have large ranges in VR.
On the Motion tab in the lower right corner you can find the VR Controller Motion Boost section.
We recommend entering initial value of 30 and reducing or increasing it using the arrows on the left until the desired effect is achieved.
This option will be helpful for disabled people with muscular dystrophy, myopathy, SMA, stroke etc.
People with spastic hands most often need VR accessibility in terms of the controller holding angle. For example a person might tend to keep their hand in specific position and have limited ability to do any manipulation.
You can set any angle of the controller position in three dimensions.
This option is mostly used by disabled people with cerebral palsy, stroke, spine injury etc.
Set the appropriate values by manually entering a value
