Abstract
Streaming applications on a smart television often render an interface into a single hardware-accelerated graphics surface. A native accessibility engine may treat that surface as one opaque node, and printed remote keycaps do not follow the content on screen. A remote control system addresses these limitations by extracting geometry and text directly from a graphics processing unit (GPU) render buffer of a host computing device. The system rebuilds a virtual accessibility tree once per render frame. Compact per-key updates travel over a low-energy wireless link to electrophoretic keycap displays, and inductive power regulation holds each keycap display at a steady voltage across the full key stroke. An ultra-wideband (UWB) pointing receiver with a directional hysteresis band and a shape-memory alloy latch reduces spurious actuation during device selection. The system can provide low-latency adaptive key labeling for hardware-accelerated interfaces.
