PALMbit:掌への光投影を利用した身体インタフェース

抄録

We propose a projection-based wearable system,"PALMbit",which enables user's palms to input control events and to output graphic information.The I/O interface for wearable computers depends largely on their practical applications.In the proposed system,we developed both an input and output method for controlling digital appliances; an optical projection onto the user's palm,which is registered by image processing,and a gesture interface based on nger actions.By projecting an image of a virtual remote controller onto the user's palm,the user is able to control digital equipment intuitively using his/her own mental body image and a haptic feedback.Experimental results with a prototype application on the proposed I/O methods show that the naturalness of images projected onto palms is superior to that of HMD-based images.
