Generic Sensor API

This directory contains the Blink part (including the JavaScript APIs exposed to users) of the Generic Sensor API.

The following concrete sensor interfaces are currently implemented:

1. Ambient Light Sensor
2. Accelerometer, Gravity Sensor and Linear Acceleration Sensor
3. Gyroscope
4. Magnetometer
5. Absolute Orientation Sensor and Relative Orientation Sensor

Some of the interfaces above depend on the SensorExtraClasses runtime flag.

The platform-specific parts of the implementation are located in services/device/generic_sensor.

Testing

Sensors web tests are part of the web-platform-tests project and are located in multiple directories under web_tests/external/wpt. For example , web_tests/external/wpt/accelerometer. The sensor-agnostic parts of the tests are located in web_tests/external/wpt/generic-sensor.

Browser tests are located in content/browser/generic_sensor.

Overall architecture

The current design of the Chromium implementation of the Generic Sensor API is described in services/device/generic_sensor.
