Designing Socially Acceptable Hand-to-Face Input
summary
Elicitation in a busy café collects 320 gestures from 10 pairs and yields five concrete interaction strategies: miniaturizing, obfuscating, screening, camouflaging and re‑purposing. Face-site analysis scores ear, neck and temple as most acceptable and forehead least. Two prototypes appear: ear-touch with a backward-facing HMD camera and thumb-to-face with a 3×3 capacitive thumbnail pad and wrist radio. Ear tap (lift-off, large target) hits 8.9% error at 2.5 s; thumb dwell at chin shows 21.5% error at 2.4 s but edge targets exceed 96% success. Validation uses six pairs and supports several strategies.
