NanoStylus: Enhancing Input on Ultra-Small Displays with a Finger-Mounted Stylus
summary
A finger-mounted thimble houses circuitry from an active capacitive stylus with a 2 mm nib extruding from the index fingertip and side capacitive pads for thumb/middle-finger gestures. A 12-participant 2D pointing study shows NanoStylus cuts error rate by ≈80% versus touch and ≈45% versus a handheld stylus, with a 20 mm nib balancing speed and occlusion; prototypes enable multi-select, hover-scroll, sketching and copy/paste on smartwatches.
