Memory in Motion: The Influence of Gesture- and Touch-Based Input Modalities on Spatial Memory

on YouTube ↗19m

" summary

Study compares three input devices — trackpad, direct touch, and Move controller — on two display sizes 10.6" vs 55" with 28 participants. Gesture input (Move) yields shorter navigation paths and better object location memory but slower task completion; touch and trackpad give higher navigation speed and lower location accuracy. Authors report a clear spatial memory vs efficiency trade-off and suggest UI fixes (overview/detail views, halos, larger hit targets) to balance memory and speed.
