Selective input system and process based on tracking of motion parameters of an input object
First Claim
1. A process for selectable input based on motion of an object associated with a user in relation to an input region having a plurality of selectable regions therein, the process comprising the steps of:
- tracking the motion of the object in relation to the input region;
determining an object path of the object, comprising a plurality of positions and corresponding times, based upon the tracked motion;
for subsequent positions and corresponding times, comparing to path data;
detecting positions that meet at least one threshold of a selected position along the determined object path, wherein the determined object path comprises at least two selected positions,wherein the threshold of a selected position within the region comprises any of starting the object path, changing direction of the object path, changing velocity of the object path, pausing motion in the object path, and ending the object path,determining which of the detected selected positions along the determined object path correspond to a selectable region; and
entering each of the detected selected positions that correspond to one of the selectable regions.

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.

10. A process for selectable input based on motion of an object associated with a user in relation to an input region having a plurality of selectable regions therein, the process comprising the steps of:
-
tracking the motion of the object in relation to the input region, wherein the tracked motion defines an object path comprising at least two selected positions; determining which of the selected positions along the object path correspond to at least one of the selectable regions; and detecting a characteristic motion of the object, the characteristic motion corresponding to at least one of the selected positions along the object path that correspond to at least one of the selectable regions wherein the characteristic motion comprises any of starting the object path, changing direction of the object path, changing velocity of the object path, pausing motion in the object path, and ending the object path. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for selectable input based on motion of an object associated with a user in relation to an input region having a plurality of selectable regions therein, the process comprising the steps of:
-
a mechanism for tracking the motion of the object in relation to the input region, wherein the tracked motion defines an object path comprising at least two selected positions; and at least one processor programmed for determining which of the selected positions along the object path correspond to at least one of the selectable regions, and detecting a characteristic motion of the object, the characteristic motion corresponding to at least one of the selected positions along the object path that correspond to at least one of the selectable regions wherein the characteristic motion comprises any of starting the object path, changing direction of the object path, changing velocity of the object path, pausing motion in the object path, and ending the object path. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
