TOUCH SCREEN AND GRAPHICAL USER INTERFACE
First Claim
1. A selective input system for a portable device, comprising:
- a touchscreen for tracking X-Y motion that corresponds to interaction of a user with said touchscreen when said user performs one or more pointing actions by moving one or more fingers over an input area of said touchscreen;
a motion and position calculation module in communication with said touchscreen for receiving information therefrom corresponding to said user pointing actions and for identifying all of input data and device function and control commands based upon said information, said motion and position calculation module determining pointing actions embodied in specific X-Y motions of one or more of said user'"'"'s fingers comprising length of motion, change in direction, change in velocity, lack of motion, path start and end points, pointing, tapping, looping, and time-based motions and/or sequences of motions at one or more locations, simultaneously or sequentially, relative to said input area; and
a processor for receiving said input data and device function and control commands from said motion and position calculation module and form operating said portable device in accordance therewith.

Abstract
A selective input system and associated method is provided which tracks the motion of a pointing device over a region or area. The pointing device can be a touchpad, a mouse, a pen, or any device capable of providing two or three-dimensional location. The region or area is preferably augmented with a printed or actual keyboard/pad. Alternatively, a representation of the location of the pointing device over a virtual keyboard/pad can be dynamically shown on an associated display. The system identifies selections of items or characters by detecting parameters of motion of the pointing device, such as length of motion, a change in direction, a change in velocity, and or a lack of motion at locations that correspond to features on the keyboard/pad. The input system is preferably coupled to a text disambiguation system such as a T9® or Sloppytype™ system, to improve the accuracy and usability of the input system.
