Buttonless display activation
First Claim
1. A method comprising:
- determining, by a first motion module of a mobile computing device and based on first acceleration data measured by one or more accelerometers at a first time, that the mobile computing device has moved, wherein a presence-sensitive display operatively coupled to the mobile computing device is deactivated at the first time;
responsive to determining that the mobile computing device has moved, activating, by a processor, a second motion module that is different than the first motion module;
responsive to determining that a standard deviation of orientation data is less than a threshold orientation standard deviation, an integral of the orientation data is greater than a threshold number of degrees, a standard deviation of second acceleration data is less than a threshold standard deviation, and absolute values of samples of the second acceleration data measured during a period of time are less than an absolute acceleration threshold, determining, by the second motion module, that the mobile computing device has moved from a first orientation to a second orientation that is different than the first orientation, wherein;
the orientation data is measured by one or more gyroscopes,the second acceleration data is measured by the one or more accelerometers during the period of time, the period of time being after the first time, andmeasuring the orientation data uses a greater quantity of power than measuring the first acceleration data; and
responsive to determining that the mobile computing device has moved to the second orientation, activating the presence-sensitive display.

Abstract
In one example, a method includes determining, by a first motion module of a computing device and based on first motion data measured by a first motion sensor at a first time, that the mobile computing device has moved, wherein a display operatively coupled to the computing device is deactivated at the first time; responsive to determining that the computing device has moved, activating a second motion module; determining, by the second motion module, second motion data measured by a second motion sensor, wherein determining the second motion data uses a greater quantity of power than determining the first motion data; determining a statistic of a group of statistics based on the second motion data; and responsive to determining that at least one of the group of statistics satisfies a threshold, activating the display.
