Automatic Sensor Selection Based On Requested Sensor Characteristics

摘要

A computing device can include or receive data from one or more sensors. Each sensor provides data regarding the environment in which the computing device is located, or the manner in which the computing device is situated or present in the environment. The computing device also includes one or more programs that make use of data received from the sensors. A sensor system of the computing device presents a sensing priority interface that allows a program to request aggregated data from the sensors. The program provides, as a parameter of the interface, an indication of sensor characteristics that are to have priority. The sensor system determines, based on the sensors supported by the computing device and the indication provided by the program, which sensors to use to obtain the aggregated data. The sensor system activates the appropriate sensors, and returns the requested aggregated data to the requesting program.

1. A method implemented in a computing device, the method comprising:
exposing a sensing priority interface having a parameter that is an indication of one or more sensor characteristics that are to be prioritized; and in response to the sensing priority interface being invoked by a program that provides the indication of one or more sensor characteristics that are to be prioritized,
identifying, based on the indication of the one or more sensor characteristics that are to be prioritized, one or more of multiple sensors from which sensor data is to be aggregated,aggregating the sensor data from the one or more sensors, andreturning the aggregated data to the program.
