CamTrackPoint: Camera-Based Pointing Stick Using Transmitted Light through Finger
summary
A low-cost prototype mounts a 3D-printed ring and spring over a phone camera and senses gestures by tracking transmitted light through the finger as a red circular blob, reporting angle and distance for continuous pointing and scrolling. Works on front and rear cameras; needs ambient light or a nearby flash for dark scenes. Battery life drops from 13 h idle to about 2 h running without flash, 80 min with flash; dropping capture from 30 to 15 fps adds ~30% life. Five-user scrolling tests show one user twice as slow but others within ~20% of swiping.
