Project Xavier

Rethinking Wheelchair Accessibility

Here at Limbitless, we also have been working on Project Xavier: a project dedicated to making wheelchairs more accessible for people with limited hand and/or arm dexterity.

The Wheelchair

Project Xavier Wheelchair

Powered by EMG Sensors

The wheelchair is powered by the same technology that controls our arms: EMG sensors picking up muscle flexes. This time, though, the sensors are placed on the temporalis muscles. When the user clenches their jaw in various ways, the wheelchair will respond by moving forward, backward, left, or right.

Hands Free Controls

By having the wheelchair being completely powered by the temporalis muscles in the head, this allows it to open the door to a whole new population of people with limited or no hand dexterity: a very important population of users who usually need access to wheelchairs.  Tasks that usually depended on someone else to push another around in a wheelchair are now much easier and less time consuming to perform, immediately improving quality of life for users.

Easy to Learn

The muscles flex patterns used to power the wheelchair are very intuitive and easy to pick up.  After just a couple of tries, most users are driving the wheelchair even around complex or crowded landscapes with ease.
