Personalization using a hand-pressure signature
First Claim
1. A method for identifying a user based on how the user grips a device with at least one of their hands, comprising:
- receiving output signals from selective pressure sensors on a pressure-sensitive body of a device, the body having a plurality of pressure sensors distributed over the pressure-sensitive body, each pressure sensor is operative to provide an output signal proportional to a pressure applied by the user'"'"'s hands to the pressure-sensitive body at the area at which the pressure sensor is located;
determining that the user is attempting to use the device based on whether a number of pressure sensors detecting pressure exerted on the device exceeds a minimum number and whether the output signals have been received for at least a minimum time period;
comparing the output signals received from the selective pressure sensors against stored pressure profile signatures responsive to said determination; and
determining the identity of the user based on a favorable comparison of the received output signals with a stored pressure profile signature associated with the user.

Abstract
A hand-held device having a body with a pressure-sensitive exterior surface. At least a portion of the pressure-sensitive exterior surface is designed to be grasped by a user'"'"'s hand. The pressure-sensitive surface contains a plurality of pressure sensors operative to provide an output signal proportional to a pressure applied by the user'"'"'s hands to the exterior surface of the hand-held device at the area the pressure sensor is located. The device also includes a memory for storing the output signals provided by the plurality of pressure sensors and a processor for comparing the output signals provided by the plurality of pressure sensors against stored pressure profile signatures for positively identifying the user.

10. A hand-held device, comprising:
-
a body with a pressure-sensitive exterior surface, whereby at least a portion of the pressure-sensitive exterior surface is designed to be grasped by a user'"'"'s hand, the pressure-sensitive exterior surface having a plurality of pressure sensors with each pressure sensor operative to provide an output signal proportional to a pressure applied by the user'"'"'s hand to the pressure-sensitive exterior surface of the hand-held device at the area the pressure sensor is located; a memory for storing the output signals provided by the plurality of pressure sensors and registered pressure profile signatures; and a processor for comparing the output signals provided by the plurality of pressure sensors against stored pressure profile signatures for positively identifying the user, said processor determines that the hand-held device is being grasped by the user based on a minimum number of pressure sensors detecting pressure exerted on the hand-held device. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for identifying a user, comprising:
-
storing multiple pressure profile signatures associated with multiple users, each pressure profile signature associated with a user is based on a position of the user'"'"'s hands grasping a device and the amount of pressure being applied to the device by the user'"'"'s hands; determining that a first user is grasping the device; receiving a first set of output signals from selective pressure sensors responsive to the pressure applied by the first user'"'"'s hands on a pressure-sensitive body of the device, the first set of output signals representing a first pressure profile; comparing the first pressure profile against the stored pressure profile signatures; determining the identity of the first user holding the device based on a favorable comparison of the first pressure profile with a stored pressure profile signature, said determining the identity of the first user comprises the steps of; if a favorable match between the first pressure profile signature and a stored pressure profile signature cannot be identified, (a) requesting the first user to grasp the device with their hands; (b) while the first user is grasping the device, capturing output signals from selective pressure sensors responsive to the pressure applied by the first user'"'"'s fingers and palm on the pressure-sensitive body of the device; (c) generating a pressure profile signature based on the captured output signals; (d) storing the generated pressure profile signature with a user identifier associated with the first user grasping the device; and (e) repeating steps (a)-(d) until a predetermined number of pressure profile signatures are stored in association with the first user; receiving a second set of output signals from selective pressure sensors responsive to the pressure applied by the first user'"'"'s hands on the pressure-sensitive body of the device, the second set of output signals representing a second pressure profile; comparing the second pressure profile against the first pressure profile; detecting a change in the pressure profile; and adjusting the functionality of the device based on detecting a change in the pressure profile. - View Dependent Claims (18, 19, 20)
