Automatic soft key adaptation with left-right hand edge sensing
First Claim
1. A system comprising:
- a sensor located at an exterior surface of an electronic device that receives presence information relating to presence of at least a portion of a hand of a user relative to the exterior surface;
a memory that stores computer executable instructions and the presence information;
a processor, communicatively coupled to the memory and sensor, that facilitates execution of the computer executable instructions to at least;
determine, based on the presence information, which hand of two user hands is being used to hold the electronic device,determine whether a position of contact with a touch screen of the electronic device has been made by a thumb of the hand determined to be holding the electronic device, andin response to a determination that the position of contact has been made by the thumb of the hand determined to be holding the electronic device;
determine an angle of the thumb with respect to the touch screen based upon a deviation of a shape of the position of contact from a circular shape, andprovide a correction factor for the position of contact based on the angle.

Abstract
Systems and methodologies for adapting input/output operation of an electronic device for left-handed and/or right-handed scenarios are provided herein. As described herein, sensors (e.g., capacitive, resistive, touch-sensitive, etc.) are applied to respective outer edges of a device to determine whether a device is in a user'"'"'s left hand and/or right hand. Based on this determination, respective points along the sensors can be mapped to soft keys to automatically optimize input for left-handed and/or right-handed operation. As further described herein, points of contact with an input device such as a touch-screen can be corrected based on whether a user'"'"'s left hand and/or right hand is holding an associated electronic device. For example, upon identifying contact between a touch-screen and a thumb of a hand being used to hold an associated device, the point of contact can be shifted to compensate for the angle of the thumb with respect to the touch-screen.

10. A method, comprising:
-
identifying, by a system including at least one processor, contact between a sensor affixed to an outer surface of a handheld device and at least a portion of a hand of a user; determining, by the system, which hand of two hands of the user is being used to hold the handheld device based on the identified contact; identifying, by the system, a position of contact with a touch screen of the handheld device; determining, by the system, whether the position of contact has been made by a thumb of the hand determined to be holding the handheld device; and in response to determining that the position of contact has been made by the thumb of the hand determined to be holding the electronic device; determining, by the system, an angle of the thumb with respect to the touch screen based upon a deviation of a shape of the position of contact from a circular shape, and providing, by the system, a correction factor for the position of contact based on the angle. - View Dependent Claims (11, 12, 13, 14, 15)

16. A non-transitory computer-readable medium having instructions stored thereon that, in response to execution, cause a handheld device to perform operations, comprising:
-
obtaining presence information relating to presence of at least a portion of at least one hand of a user on an exterior surface of the handheld device; determining which hand of two hands of the user is being used to hold the handheld device based on the presence information; identifying a point of contact with a touch screen of the handheld device; determining whether the point of contact has been made by a thumb of the hand determined to be holding the handheld device; and in response to determining that the point of contact has been made by the thumb of the hand determined to be holding the electronic device; determining an angle of the thumb with respect to the touch screen based upon a deviation of a shape of the position of contact from a circular shape, and providing a correction factor for the position of contact based on the angle.
