Glasschair is a Google Glass app that helps people with disabilities to get mobile independently through hands-free wheelchair driving. For those people with disabilities who need an assistant to wheel them due to lack of hand motor control or strength, this app allows you to drive your wheelchair without using your hands. With head movements and voice commands you steer your wheelchair. After the adapter is connected, you can start driving straight away.
