Abstract
The present disclosure is directed to routine recognition for adjusting the power state of a device. Human activity recognition is performed to detect various activity states, and create a current sequence of activity states. In response to detecting a new activity state, routine comparison is performed in order to compare the current sequence to a past sequence that ended with the user starting to interact with the device. The device is preemptively turned on in response to finding a match.
Claims16
A device, comprising:
- a motion sensor configured to generate motion measurements;
- and
- a processor coupled to the motion sensor, the processor configured to:
- detect a plurality of activity states based on the motion measurements, the detected plurality of activity states including a stationary state in which the device has a determined amount of movement, a walking state in which a user is walking with the device, and a transport state in which the user is traveling in a vehicle with the device;
- generate a current sequence of activity states based on the detected plurality of activity states;
- compare the current sequence of activity states to a database sequence of activity states stored in a database;
- and
- set the device to an ON state in a case where the current sequence of activity states corresponds to the database sequence of activity states.

A method, comprising:
- generating motion measurements of a device;
- detecting a plurality of activity states of the device based on the motion measurements, the detected plurality of activity states including a super still state in which the device remains still, a stationary state in which the device has a determined amount of movement, a walking state in which a user is walking with the device, and a transport state in which the user is traveling in a vehicle with the device;
- generating, in response to detecting a transition from the super still state to another activity state after the super still state has been detected consecutively for a determined amount of time, a current sequence of activity states that includes activity states of the detected plurality of activity states;
- determining whether or not the current sequence of activity states corresponds to a database sequence of activity states that terminates with the user interacting with the device;
- setting the device to an ON state in a case where the current sequence of activity states corresponds to the database sequence of activity states;
- and
- determining whether or not the current sequence of activity states corresponds to another database sequence of activity states that terminated with the user interacting with the device in a case where the current sequence of activity states does not correspond to the database sequence of activity states.
