Pressure-sensitive touch screen display and method

A method for a user to interact with an electronic device comprising:

• providing a touch screen display on the device that comprises a pressure-sensitive interface that is capable of detecting a plurality of pressures when a user selects a displayed item on the touch screen display and interpreting each of the plurality of pressures as a different action with respect to the displayed item;
• generating a first pressure map for a first orientation of the electronic device, the first pressure map comprising a first plurality of pressure thresholds for each of a plurality of sections of the touch screen display;
• providing a second pressure map for a second orientation of the electronic device, the second pressure map comprising a second plurality of pressure thresholds for each of the plurality of sections of the touch screen display;
• determining a physical orientation of the device is the first orientation;
• and
• dynamically monitoring a user's interactions with the touch screen display in the first orientation, detecting when pressure detection was incorrect by detecting when the user selects a pressure-sensitive item a first time then selects the pressure-sensitive item a second time with a different pressure, and updating at least one of the first plurality of pressure thresholds based on the user's monitored interactions in the first orientation.

An article of manufacture comprising software stored on a computer readable storage medium, the software comprising:

• a pressure-sensitive interface mechanism that dynamically monitors a user's interaction with a touch screen display on an electronic device in a first orientation, detecting when pressure detection was incorrect by detecting when the user selects a pressure-sensitive item a first time then selects the pressure-sensitive item a second time with a different pressure, the touch screen display comprising a pressure-sensitive interface that is capable of detecting a plurality of pressures when a user selects an item on the touch screen display and interpreting each of the plurality of pressures as a different action with respect to the displayed item, generates a first pressure map for a first orientation of the electronic device, the first pressure map comprising a first plurality of pressure thresholds for each of a plurality of sections of the touch screen display, generates a second pressure map for a second orientation of the electronic device, the second pressure map comprising a second plurality of pressure thresholds for each of the plurality of sections of the touch screen display;
• determining a physical orientation of the device is the first orientation and that dynamically updates at least one of the first plurality of pressure thresholds based on the user's monitored interactions with the touch screen display in the first orientation.

An electronic device comprising:

• at least one processor;
• a memory coupled to the at least one processor;
• a touch screen display coupled to the at least one processor, the touch screen display comprising a pressure-sensitive interface that is capable of detecting a plurality of pressures when a user selects an item on the touch screen display and interpreting each of the plurality of pressures as a different action with respect to the displayed item;
• an orientation mechanism that determines physical orientation of the device;
• a pressure-sensitive interface mechanism residing in the memory and executed by the at least one processor, the pressure-sensitive interface mechanism comprising:
• a calibration mechanism that prompts the user to touch a plurality of regions on the touch screen display using a plurality of pressures with the device in a plurality of orientations, and logs the plurality of pressures, wherein the plurality of regions on the touch screen display each comprises at least one of a plurality of sections of the touch screen display;
• a pressure mapping mechanism that generates from the logs a first pressure map of the touch screen display that includes:
• a first orientation of the device;
• a first plurality of sections of the touch screen display;
• and
• for each one of the first plurality of sections of the touch screen display, a first plurality of pressure thresholds customized to the user based on the plurality of pressures the user uses to touch the one of the first plurality of sections of the touch screen display;
• wherein the pressure mapping mechanism generates from the logs a second pressure map of the touch screen display that includes:
• a second orientation of the device;
• a second plurality of sections of the touch screen display;
• and
• for each one of the second plurality of sections of the touch screen display, a second plurality of pressure thresholds customized to the user based on the plurality of pressures the user uses to touch the one of the second plurality of sections of the touch screen display;
• a usage monitor mechanism that dynamically monitors a user's interaction with the touch screen display, detects when pressure detection was incorrect by detecting when the user selects a pressure-sensitive item a first time then selects the pressure-sensitive item a second time with a different pressure, and adjusts at least one of the plurality of pressure thresholds based on the user's monitored interactions;
• and
• wherein the pressure-sensitive interface mechanism detects pressure on a displayed item in a selected region of the touch screen display, determines from an orientation of the device and a pressure map corresponding to the orientation a plurality of pressure detection thresholds for the selected region of the touch screen display, and takes action based on the detected pressure on the displayed item and the plurality of pressure detections thresholds for the selected region of the touch screen display.
