A SteamVR overlay app for the Steam Frame. A double knock (controllers together, a controller on a surface, or a tap on the headset) turns Room View on or off. A triple knock switches translucent and opaque. Includes the knock detector with replay tests on recorded poses, the debug port client for the Room View button, per-game blocklist, calibration, haptics, install and autostart, and FrameDrop packaging.
