hardware and wearables

ideas for physical devices spanning sensory capture (sensory recording, olfactory fatigue reset), human-computer interaction (eye tracking, EMG bracelet), practical utility (face recognition doorbell, warming blanket, teleprompter), and fun (movie laser grid).

the smell resetter has the deepest research — extensive exploration of olfactory fatigue mechanisms, retronasal vs orthonasal delivery, and existing work in electronic noses. the sensor capturer is the most ambitious (rated highest impact in build-notes evaluation). the HCI devices (pupilometry, EMG) may be superseded by Apple Vision Pro and Meta smart glasses.
