Thumbles: a Touchscreen Interface Based on Little Mobile Robots
Touchscreens are the physical interface of choice right now. This is fine, because touchscreens are versatile and portable, and we like them. Sometimes, however, we feel that they lack that satisfying tactile feedback we get from physical controls like buttons and knobs and joysticks.
Now an experimental interface called Thumbles wants to bring more tactile capability to the touchscreen. It features tiny little omnidirectional robots that live on top of a projected screen. By grabbing them and dragging them around as they try to drive around, you can experience a completely new type of physical interactivity.
