Method using a finger above a touchpad for controlling a computerized system
First Claim
1. A method for controlling an input from a user to a computerized system including a touchpad, the method comprising:
- obtaining data from the touchpad, the data being associated with the location and movement of arbitrarily positioned fingers and/or a hand of the user and not associated with an image of said fingers from an image sensor, when the user operates the computerized system using the touchpad;
communicating the data from the touchpad to the computerized system;
analyzing the data in accordance with a model of a human hand;
determining, using the model, that at least one identified finger of the user is positioned above but not touching a first control region of the touchpad;
determining that the at least one identified finger is subsequently touching the first control region in accordance with the data and the model after the at least one identified finger is positioned above but not touching the first control region; and
storing a record that the at least one identified finger is subsequently touching the first control region within a first period of time less than or equal to 10 seconds after the at least one identified finger is positioned above but not touching the first control region.

25. A method for controlling an input from a user to a computerized system including a touchpad, the method comprising:
-
obtaining data from the touchpad, the data being associated with the location and movement of arbitrarily positioned fingers and/or a hand of the user and not associated with an image of said fingers from an image sensor, when the user operates the computerized system using the touchpad; communicating the data from the touchpad to the computerized system; analyzing the data in accordance with a model of a human hand; determining, using the model, that at least one identified finger of the user is positioned above but not touching a first control region of the touchpad; determining that the at least one identified finger is initially touching the first control region in accordance with the data and the model before the at least one identified finger is positioned above but not touching the first control region; generating a first graphical representation on a display screen of the computerized system, the first graphical representation being associated with the first control region; displaying the first graphical representation with a first appearance when the at least one identified finger is initially touching the first control region; and displaying the first graphical representation with a second appearance different than the first appearance when the at least one identified finger is positioned above but not touching the first control region; wherein the displaying the first graphical representation with a second appearance occurs for a first period of time less than or equal to 10 seconds.

26. A method for controlling an input from a user to a computerized system including a touchpad, the method comprising:
-
obtaining data from the touchpad, the data being associated with the location and movement of arbitrarily positioned fingers and/or a hand of the user and not associated with an image of said fingers from an image sensor, when the user operates the computerized system using the touchpad; communicating the data from the touchpad to the computerized system; analyzing the data in accordance with a model of a human hand; determining, using the model, that at least one identified finger of the user is positioned above but not touching a first control region of the touchpad; determining that the at least one identified finger is subsequently touching the first control region in accordance with the data and the model after the at least one identified finger is positioned above but not touching the first control region; determining that the at least one identified finger is moving or sliding on the first control region after subsequently touching the first control region; storing a record of the moving or sliding of the at least one identified finger; and generating a first graphical representation on a display screen of the computerized system, the first graphical representation being associated with the first control region, wherein the first control region includes a length substantially greater than the longitudinal length of a surface region of the at least one identified finger when contacting the touchpad.
