DETECTING BACKSIDE FORCE IN A TOUCH-SCREEN DEVICE
First Claim
1. A method for detecting back-side force in a mobile device, the method comprising:
- measuring, by a force sensor of the mobile device, force applied to a surface of the device;
detecting, by a touch sensor of the mobile device, one or more touch contacts;
determining, by a processor circuit of the mobile device, whether the measured force correlates to at least one of the one or more touch contacts;
in response to determining that the measured force correlates to the at least one of the one or more touch contacts, initiating, by the processor circuit, a front-side force specific action; and
in response to determining that the measured force does not correlate to at least one of the one or more touch contacts, initiating, by the processor circuit, a back-side force specific action.

Abstract
In one aspect, the present disclosure relates to a method including detecting force applied to a force sensing layer in a device and detecting touch contacts applied to a touch screen layer in a device. The method also includes determining if the location and/or amount of force detected by the force sensing layer correlates to a touch contact, and, if it correlates, treating the force as front-side force, while if the location and/or amount of force detected by the force sensing layer does not correlate to a touch contact, treating the force as a back-side force. Based on the type of force detected, appropriate action may be taken, including back-side specific actions such as multi-tasking application switches or content or viewport manipulation.

11. A system for detecting back-side force in a mobile device, comprising:
-
a force sensor configured to measure force applied to a surface of the device; a touch sensor configured to detect one or more touch contacts; and a processor circuit coupled to the force sensor and the touch sensor, and configured to execute instructions causing the processor to; determine whether the force measured by the force sensor correlates to at least one of the one or more touch contacts; in response to determining that the measured force correlates to the at least one of the one or more touch contacts, initiate a front-side force specific action; and in response to determining that the measured force does not correlate to at least one of the one or more touch contacts, initiate a back-side force specific action. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
