Ubiquitous grasp interfaces

Sensory hand augmentation extends the manual function spectrum from controlling analogue objects to digital or smart objects but also might add an interface to any graspable thing and therefore add a digital interface to everyday objects. We propose a finger-attached interface to control grasped objects intended to explore design parameters for always available interfaces. Our device detects finger motions and classifies them according to a set of five gestures. In user studies we found that our gesture classification has a stable performance with respect to different organic-shaped surfaces. Finally, the scalability of our approach towards generic object control will point out its potential.
