Abstract :
Three-dimensional coordinates of multiple fingers are acquired by a camera equipped with a fisheye lens and LEDs covered by a transparent hemispherical shell. Finger deformation induced by touch events is identified from the captured images, making the device compatible with the conventional mouse.
