The Bar of Soap, created by Michael Bove, Stacie Slotnick and Brandon Taylor at the MIT Media Laboratory, is a handheld device that recognizes how it is being held and adjusts its functionality accordingly. For instance if you want to make a phone call, just hold the bar of soap like a phone!
The device senses the pattern of touch and orientation when it is held, and reconfigures to become one of a variety of devices, such as phone, camera, remote control, PDA, or game machine. Pattern-recognition techniques allow the device to infer the user's intention based on grasp. We are now adding display surfaces across the entire device so that buttons and indicators can be created where needed for a particular mode.
