- We present a novel hand gesture interaction method which
has a long-range working space (1m~5m) overcoming conventional ap-
proaches' limitations in cost-performance dependency. Our camera-free
interaction system is composed of a pair of lighting device and an instru-
mented glove with photosensor markers. The lighting devices spatiotem-
porally encode user's interaction space via binary infrared light signals
and markers' 3D position at fingertips is tracked at high speed (250 Hz)
and fair accuracy (5mm at 3m working distance). Each marker consisting
of a photosensor array allows a wide sensing range and minimizes n-
gers' self-occlusion. Experiment results demonstrate various applications
where hand gestures are recognized as input commands to interact with
digital information mimicking natural human hand gestures toward real
objects. Our system has strengths in accuracy, speed, low price, and ro-
bustness comparing with conventional long-range interaction techniques.
Ambiguity-free nature in marker recognition and little cost-performance
dependency are additional advantages of our method.
