PiperXR

Thermal-aware pipeline SDK for Android XR

Smart glasses throttle. PiperXR keeps the session alive.

Smart glasses have no fans, minimal mass, and a tiny battery. When they overheat, the OS cuts everything indiscriminately. PiperXR adjusts the data pipeline intelligently before the thermal governor has to.

Enterprise smart glasses workloads warehouse picking, field service, remote expert video are continuous data pipelines. Sustained inflow plus WiFi uplink plus rendering is exactly the workload that hits the thermal wall first. Today the only response is the OS thermal governor: a blunt, session-killing hard cut.

  • Data inflow management Monitors ADPF thermal headroom in real time; reduces update frequency, batches non-critical data, and pauses background sync as headroom shrinks graduated states instead of a hard cut.
  • WiFi transmission control Batches transmissions, negotiates bitrate down under thermal stress, and releases WiFi locks when the radio doesn't need to be hot. The radio is one of the highest-power components on the board.
  • Gaze-aware rendering roadmap Reduces render frequency in peripheral gaze zones via OpenXR eye tracking, recovering GPU load where the user isn't looking.

PiperXR targets Android Dynamic Performance Framework (ADPF) and OpenXR 1.1 the vendor-neutral layer. No per-vendor SDK lock-in. Designed for Android XR, compatible by design with Meta Wearables and XREAL toolchains.

headroom < 0.60      NOMINAL   full quality
0.60 – 0.75          WARM      reduce WiFi aggression
0.75 – 0.90          HOT       bitrate −50%, fps down

Every PiperXR performance claim will be verified by Time2Throttle, an independent thermal and battery benchmark lab with a published, versioned, CC BY 4.0 methodology and hash-anchored public results. Until those benchmarks are published, PiperXR makes no performance claims the methodology exists so the claims can be falsified.
