Very interesting, lots of room for improved UX with more sensors to more efficiently communicate opponent moves - "long presses", double and triple taps, "shake your foot", rolls, heel lifts ... if you could get this down to < 2 seconds I think you're in real business. Also for things like "captures-captures" or "only move" some shortcuts would be handy. Maybe some hand and brain style options where you or it select the piece and the other suggests a move ... Wiring up each toe and mapping to a piece type could expedite move suggestion inputs ...
