DriftBoard: A Panning-Based Text Entry Technique for Ultra-Small Touchscreens
summary
A panning-based movable QWERTY keyboard with a fixed cursor is implemented for watch-sized screens (interactive area 28×14 mm) so each key is reachable with one pan and selection occurs on finger lift. A 10-participant study (1,455 trial phrases) compares DriftBoard to ZoomBoard and Swipeboard: panning-based movable QWERTY, 28×14 mm interactive area, measured speeds are 9.7 WPM (0.6% MSD error) for DriftBoard, 10 WPM (1.35%) for ZoomBoard, 8.5 WPM (2.46%) for Swipeboard; statistical tests show DriftBoard ≈ ZoomBoard and better than Swipeboard.
