Microsoft's Gesture-Based Multifunctional Stylus
A recent prototype design becomes different devices as its position in space is changed.
Microsoft's Kinect broke considerable ground in gesture-based computer interaction, and their latest prototype continues to make interesting advances in gestural interfaces. However, the prototype stylus they recently debuted has a stronger focus on touch.
The user holds the stylus in the grip most natural to the task at hand, whether that be drawing or erasing, and the device will mirror its functionality accordingly:
“It pays attention to how the device is being held and moved, and changes to one of eight different preset functionalities on the fly.”
