Abstract
Avoiding latency in booting or waking a device requires keeping it on and connected at all times, resulting in poor battery life, frequent recharging, limited mobility because of the need for a connection, and higher costs. Sensor-based functionality for automatically triggering device start or wake by sensing human presence requires expensive sensors, does not identify specific users, generates many false positives, and lacks uniformity across devices. This disclosure describes implementation of a context-aware standby state and context-aware boot process with low-cost hardware integrated within a device. A device in the shutdown or suspended state can be switched to the context-aware standby state based on increasing proximity of the user to the device. The distance between the device and the user can be determined with user permission by connecting with a companion device via Bluetooth Low Energy (BLE). A device in the context-aware standby state can operate between the fully active and suspended states by keeping a single-core low-power processor fully operational while other power-intensive components remain in the suspended state. Such a device can be switched to the active state without noticeable latency upon receiving user input within a specified interval. If no user input is received and/or the user moves away, the device returns to the suspended or turned off state.
