Brazilian start-up Hoobox Robotics has collaborated with Intel to produce an adapter kit that allows almost any electric wheelchair to be controlled by the user's facial expressions. The Wheelie 7 kit equips a wheelchair with artificial intelligence to detect the user's expressions and process the data in real-time to direct the movement of the chair. Smiling, raising the eyebrows, wrinkling the nose or puckering the lips as if for a kiss are among the repertoire of 10 gestures recognised by the prototype Wheelie 7. Users can customise which of the 10 expressions they want to employ for each possible direction, so they can play to their strengths. "We believe we can take advantage of a person's best abilities to counteract limitations, not only improving mobility and autonomy, but also enhancing self-esteem," said Paulo Gurgel Pinheiro, the designer behind Wheelie 7.
