Abstract
A user device having an active application periodically detects for a hands-off state of the user device. Upon detecting a hands-off state, the user device affects at least one of the active application and the user device. Prior to affecting at least one of the active application and the user device, the user device detects for one or more of a connection between the user device and another device, and an application of pressure to the user device. If either is detected the, the user device bypasses affecting at least one of the active application and the user device.
Claims24
A method of controlling a user device, comprising:
- periodically detecting for a hands-off state of the user device having an active application;
- detecting, based on detecting the hands-off state of the user device, whether there is an absence of a connection between the user device and another device;
- detecting, based on detecting the absence of the connection between the user device and another device, whether there is an absence of an application of pressure to the user device;
- and
- transitioning the user device to a low-power mode, based on detecting the hands-off state of the user device, based on detecting the absence of the connection between the user device and another device, and based on detecting the absence of the application of pressure to the user device.
