Indutivo: Contact-Based, Object-Driven Interactions with Inductive Sensing

on YouTube ↗18m

" summary

Contact-based inductive sensing recognizes conductive household objects and tracks sliding, hinging and rotation on a smartwatch by using a circular array of five coils, an LC‑tank read by a Texas Instruments inductance sensor, and a small TFT for feedback. A collected footprint database enables real‑time matching with 95.8% object classification, sliding error under 1 mm on average, hinge error ~1.64°, and 93% rotation accuracy. Demonstrations include app launch, sliding control and hinge-triggered calorie logging five-coil array, LC-tank inductance readout, 95.8% classification accuracy.
