BIMODAL USER INTERFACE PARADIGM FOR TOUCH SCREEN DEVICES
First Claim
1. A method of bi-modal touch screen interaction for a touch screen device, the method comprising:
- detecting an area of finger interaction upon a touch screen surface;
determining, based on at least one of a size, a shape, and an orientation of the detected area of finger interaction, whether the finger interaction is one of;
a finger-tip interaction type and a finger-pad interaction type; and
implementing, based on the determined interaction type, one of two different targeting modes, including a first targeting mode implemented in response to a determined finger-tip interaction type and a second targeting mode implemented in response to a determined finger-pad interaction type.

Abstract
A touch screen device provides bi-modal user interaction. The touch screen device includes (a) a touch screen interface, (b) a detector to detect an area of finger interaction with the touch screen surface, and (c) a processor. The processor determines, based on at least one of a size, a shape, and an orientation of the detected area of finger interaction, whether a current finger interaction is of one of: a finger-tip interaction type and a finger-pad interaction type. The processor also selects and implements, based on a determined interaction type, one of two different targeting modes, including a first targeting mode selected and implemented in response to a determined finger-tip interaction type and a second targeting mode selected and implemented in response to a determined finger-pad interaction type. In a preferred embodiment, the first targeting mode is direct-targeting mode and the second targeting mode is an offset-targeting mode.

28. A method of bi-modal user interaction for a touch screen device, the method comprising:
-
detecting an area of finger interaction upon a touch screen surface;
repeatedly determining, for the detected area of finger interaction, an elapsed time of continuous interaction with the touch screen surface; and
implementing, based upon a currently determined elapsed time, one of two different targeting modes, including a first targeting mode to implement in response to an elapsed time being less than threshold value and a second targeting mode to implement in response to the elapsed time being greater than the threshold value. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
