Selective input system based on tracking of motion parameters of an input device
First Claim
1. A process for selectable input based on motion of a pointing device in relation to a region, the process comprising the steps of:
- tracking the motion of the pointing device in relation to the region;
determine a device path of the pointing device, comprising a plurality of positions and corresponding times, based upon the tracked motion;
for subsequent positions and corresponding times, compare to path data;
detecting subsequent positions which meet at least one threshold of a selected position within the region; and
entering each of the selected positions which correspond to a selection.

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.
