PROBLEM:<\/strong> People experiencing finger -specific motor disabilities are often asked to participate in rehabilitation sessions, either within clinical settings or at home. Unfortunately, a lot of them (including me) do not execute the instructed exercises for finger strengthening and as a result their traumatised fingers may not fully recover back to their original potential.<\/p>\n

SOLUTION: <\/strong>RehabActuators constitute a portable, soft robotic wearable that exploits tangible interaction to motivate patients to execute finger exercises like bending\/unbending. RehabActuators turns rehabilitation into a playful activity, where the participant can manipulate its own finger by using interacting with the interface.<\/p>\n
