Abstract

A touchpad pointing device utilized as a pattern input device for a pattern recognition system. The input pattern received from the touchpad pointing device is translated into a start application command. The recognition system forms part of a computer having an operating system and includes a touchpad pointing device, a recognition module and a signal capturer. In addition, a unit for launching an application to run on a computer having an operating system and a pointing device which produces an input pattern in response to movement upon it, is described. The unit includes a recognition module and a launcher. The recognition module attempts to recognize the input pattern as a previously trained launching pattern. The launcher launches the application by providing a launching command which is associated with the launching pattern to the operating device. A security application enables access to the computer upon receipt of an input signature from a user with access privileges.

Claims

1. An application launching system comprising:

a computer;

a touchpad pointing device in operative communication with said computer;

a launching manager operative to receive an activation signal and thereafter operate said touchpad pointing device in a pattern input mode and receive a pattern input via said touchpad pointing device; and

pattern matching means operative to;

receive said pattern from said launching unit while said touchpad pointing device is in said pattern input mode;

compare said pattern to at least one preprogrammed pattern; and

provide an identifier associated with said pattern to said launching manager where said input matches said preprogrammed pattern,

wherein said launching manager is operative to identify an application on said computer that is in predefined association with said identifier and launch said application.

2. A system according to claim 1 wherein:

said touchpad pointing device is operative in a pointing device mode prior to said launching manager receiving said activation signal; and

said launching manager is additionally operative to return said touchpad pointing device to said pointing device mode upon launching said application.

3. A system according to claim 1 and further comprising training means operative to create a plurality of said predefined association between a plurality of said application and a plurality of said identifier.

4. A system according to claim 1 wherein said launching manager is operative to receive a deactivation signal and thereafter operate said touchpad pointing device in a pointing device input mode.

5. A system according to claim 4 wherein said deactivation signal is any of a hot-key entry, a menu selection, and a termination directive to said recognition apparatus.

6. A system according to claim 1 wherein said activation signal is any of a hot-key entry, a menu selection, a voice command, and a hand-written pattern.

7. A system according to claim 1 wherein said pattern is any of a word, gesture, a character, and a signature.

8. A system according to claim 1 wherein said pattern is handwritten.

9. A system according to claim 1 wherein said application is a security application enabling further access to said computer.

10. A system according to claim 1 wherein said touchpad pointing device is either of a touchpad and a mouse.
