Meet the MobiLimb: a robotic finger with 5 degrees of freedom that can be easily added to your mobile device, allowing them to move and interact with you. As this video from Marc Teyssier shows, the MobiLimb can work as a grip or stand for your phone. It can also move to notify you when you have notifications.
The MobiLimb detects touch on its surface. Angles of each motor are detected to allow manipulation.The device has a plug & play design and can be attached to most mobile devices.
