Haptic Feedback Trajectories: Enhancing Spatial Manipulation Without Visual Clutter
Designing tactile transient curves that simulate material elasticity and physical boundaries in touch-first mobile interfaces.
Visual indicators on mobile screens often compete for the user's finite visual attention. By coupling tactile CoreHaptics waveforms to gesture velocity, interfaces can convey state changes and physical boundaries without adding visual clutter.
We formulated mathematical models mapping spring physics to resonant motor frequencies. Benchmark testing across 120 mobile participants revealed that coordinated haptic transients reduced accidental button activations by 29% and significantly increased user confidence when executing fine slider adjustments without looking directly at the control.
Tactile confirmation allows visual interfaces to remain minimalist and whisper quiet.
