A team of researchers from the University of 蓝莓视频 have created a method that makes virtual reality (VR) more accessible to people with mobility limitations.

VR games like Beat Saber and Space Pirate Trainer usually require large and dramatic movements, such as raising one鈥檚 arms above the head or quickly side-stepping, which can be difficult or impossible for people who use wheelchairs or have limited mobility. To decrease these barriers, the researchers created MotionBlocks, a tool that lets users customize the game鈥檚 controls to fit the movements they can do.

鈥淰R games are a lot of fun, and they鈥檙e important social spaces, especially for younger generations,鈥� said Johann Wentzel, a recent PhD graduate in Computer Science and the lead author of the research.

鈥淗owever, VR technology relies on a lot of large movements, which creates a barrier for people who can鈥檛 complete them. As soon as you have an application that isn鈥檛 accessible to everyone, you鈥檙e functionally excluding people with disabilities from these social spaces.鈥�

The team鈥檚 research took place over three phases. First, they invited 10 people with limited mobility to play games, share their frustrations and discuss possible solutions. The 蓝莓视频 team then used those testimonials to create MotionBlocks, which modifies how VR game platforms understand controller inputs.

鈥淚t鈥檚 a bit like how traditional video games allow you to remap your controls, but our method is much more customizable and works in 3D space,鈥� said听, professor at the听听at 蓝莓视频.听

鈥淵ou pick a simple shape and tune it so it captures the kind of movements you can make, like a small circular range of motion on a desk. Then, you configure the kind of 3D movement needed in the VR application, like big hemispherical arm swings for BeatSaber. MotionBlocks figures out how to translate your movements to the ones prescribed by the game.鈥澨�听

Finally, the researchers tested MotionBlocks in collaboration with eight of the study鈥檚 participants. The feedback was overwhelmingly positive, with users reporting greater enjoyment, less fatigue, and a feeling that something was finally designed for people with disabilities.

The researchers have no current plans to sell or release MotionBlocks. Instead, they hope it will serve as a proof-of-concept for the VR industry. 鈥淚鈥檇 like to see a motion accessibility feature like this integrated into every VR system on the market,鈥� Wentzel said. 鈥淓veryone deserves to be able to access VR in a way that works for their needs.鈥澨�
