Dwell++: Haptic-Augmented Multi-Level Touch
summary
Dwell+ augments long presses with short 10 ms vibrotactile pulses and tests 170, 150, 130 and 110 ms intervals to enable multi-level single‑touch selection. A simple 3-beats-per-chunk rhythm (extend the first tick of every three) boosts counting and yields ~94.5% accuracy for 10 levels at the 170 ms interval and ~93.8% for 5 levels at 150 ms. The prototype uses phone/watch haptics separate from the touch surface and works for smartwatch typing, stylus tool pickers, and single‑button inputs.
