Wearable Subtitles: Augmenting Spoken Communication with Lightweight Eyewear for All-day Captioning
summary
A lightweight head-worn captioning system implements a hybrid low-power architecture around a MediaTek MT2523D Cortex-M4 SOC and BLE radio, an 8-layer temple PCB and microdisplay, and mechanical fittings that reduce nose load from 78% to 56% by moving batteries behind the ears. Engineering fixes include a chip antenna and fault-tolerant Bluetooth firmware; display and power tuning approach 15 hours of use. User work includes a n=501 survey and three studies with 24 participants plus 6 one-hour comparisons.
