1. A system for generating a multi-touch command, comprising:
- a single-touch sensor pad;
an imaging sensor disposed adjacent to the single-touch sensor pad, the imaging sensor being configured to capture one or more images of a user'"'"'s fingers on or above the single-touch sensor pad; and
firmware configured to acquire data from the single-touch sensor pad and use it with the one or more images from the imaging sensor to generate a multi-touch command.

Abstract
A system and method for generating a multi-touch command using a single-touch sensor pad and an imaging sensor is disclosed. The imaging sensor is disposed adjacent to the single-touch sensor pad and captures images of a user'"'"'s fingers on or above the single-touch sensor pad. The system includes firmware that acquires data from the single-touch sensor pad and uses that data with the one or more images from the imaging sensor to generate a multi-touch command.

9. A method for generating a multi-touch command with a single-touch sensor pad, the method comprising:
-
acquiring data from a single-touch sensor pad, the data identifying the presence or absence of a touchpoint on the single-touch sensor pad, the data further identifying the position of the touchpoint when the data identifies the presence of a touchpoint, the touchpoint resulting from one or more fingers of a user contacting the single-touch sensor pad; acquiring one or more images of the user'"'"'s one or more fingers from an imaging sensor; identifying, using firmware, a hand gesture made by the user'"'"'s one or more fingers using the data from the single-touch sensor pad and the one or more images; and generating, using the firmware, a multi-touch command based on the identified hand gesture. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for generating a multi-touch command with a single-touch sensor pad, the method comprising:
-
acquiring data from a single-touch sensor pad, the data identifying the presence or absence of a touchpoint on the single-touch sensor pad, the data further identifying the position of the touchpoint when the data identifies the presence of a touchpoint, the touchpoint resulting from one or more fingers of a user contacting the single-touch sensor pad; acquiring one or more images of the user'"'"'s one or more fingers from an imaging sensor; identifying, using firmware, a hand gesture made by the user'"'"'s one or more fingers using the data from the single-touch sensor pad and the one or more images when the data identifies the presence of a touchpoint on the single-touch sensor pad, and identifying a hand gesture using only the one or more images when the data identifies the absence of a touchpoint on the single-touch sensor pad; and generating, using the firmware, a multi-touch command based on the identified hand gesture.
