Abstract
A method involves, via a sensor application interface, 1) receiving, from an application, a measurement request associated with a quality-of-service control; 2) in accord with the quality-of-service control, obtaining measurement data from a sensor; and 3) returning to the application i) the measurement data obtained from the sensor, and ii) an indicator of accuracy of the measurement data.
Claims27
A method, comprising:
- via a sensor application interface:
- receiving, from an application, a measurement request for direction and orientation measurements and at least one input quality-of-service control associated with the direction and orientation measurements;
- in accord with the at least one input quality-of-service control, obtaining raw measurement data corresponding to the direction and orientation measurements from a plurality of sensors comprising at least two accelerometers;
- and
- returning to the application, at least a portion of the raw measurement data and an output quality-of-service control indicating an expected accuracy of at least one of the plurality of sensors in generating at least the portion of the raw measurement data, wherein the expected accuracy is based, at least in part, on a measurement period specified in the at least one input quality-of-service control.

An apparatus having a sensor to sense linear motion and orientation information, the apparatus comprising:
- a first accelerometer;
- a second accelerometer, wherein the first and second accelerometers are integrated to sense linear motion information by producing similar outputs and orientation measurements by producing opposing outputs;
- and
- processor circuitry to execute operations for a sensor application interface, the operations to:
- receive, from an application, a request for the linear motion and orientation measurements and at least one input quality-of-service control associated with at least one of the linear motion measurements or the orientation measurements,
- in accord with the at least one input quality-of-service control, obtain raw measurement data from at least the first and second accelerometers, and
- return, to the application, at least a portion of the raw measurement data for at least the linear motion and orientation measurements and an output quality-of-service control indicating an expected accuracy of at least the first and second accelerometers in generating at least the portion of the raw measurement data, wherein the expected accuracy is based, at least in part, on a measurement period specified in the at least one input quality-of-service control.
