Tilt-Explore: Making Tilt Gestures Usable for Low-Vision Smartphone Users
summary
Tilt-Explore is a tilt-to-pan mode added to screen magnifiers that activates by touch-and-hold 800 ms and uses audio-haptic cues plus a dynamic reference (eta=0.8, lambda=5s) to capture wave-like tilt motions. Two studies (12 formative, 16 summative low-vision participants) evaluate the prototype: participants use 80% fewer panning gestures and show 95% fewer accidental taps, and users under 45 or using <4x magnification are faster; reading speed remains low (max 44 WPM).
