identifying, by the computer processor, pre-defined gestures in the video signal; and generating, by the computer processor, computer commands corresponding to the pre-defined gestures in the video signal. ### Claim 2 (depends on 1) The non-transitory, tangible computer-readable medium of claim 1, wherein the method further comprises: transmitting, by the computer processor, the computer commands to an application executed by the processor. ### Claim 3 (depends on 1) The non-transitory, tangible computer-readable medium of claim 1, wherein the method further comprises: transmitting, by the computer processor, the computer commands to a remote computer. ### Claim 4 (depends on 2) The non-transitory, tangible computer-readable medium of claim 2, wherein the application is a presentation program and the computer commands are for controlling the presentation program. ### Claim 5 (depends on 3) The non-transitory, tangible computer-readable medium of claim 3, wherein the method further comprises: identifying, by the computer processor, a pre-registered user by facial recognition; and identifying, by the computer processor, the pre-defined gestures in the video signal performed by the pre-registered user. ### Claim 6 (depends on 1) The non-transitory, tangible computer-readable medium of claim 1, wherein the video signal is received from only a single camera. ### Claim 7 A computer-implemented method for gesture-based computer control, comprising the steps of: receiving, by a computer processor, a video signal; identifying, by the computer processor, pre-defined gestures in the video signal; and generating, by the computer processor, computer commands corresponding to the pre-defined gestures in the video signal. ### Claim 8 (depends on 7) The computer-implemented method of claim 7 further comprising: transmitting, by the computer processor, the computer commands to an application executed by the processor. ### Claim 9 (depends on 7) The computer-implemented method of claim 7 further comprising: transmitting, by the computer processor, the computer commands to a remote computer. ### Claim 10 (depends on 8) The computer-implemented method of claim 8, wherein the application is a presentation program and the computer commands are for controlling the presentation program. ### Claim 11 (depends on 8) The computer-implemented method of claim 8 further comprising: identifying, by the computer processor, a pre-registered user by facial recognition; and identifying, by the computer processor, the pre-defined gestures in the video signal performed by the pre-registered user. ### Claim 12 (depends on 7) The computer-implemented method of claim 7, wherein the video signal is received from only a single camera. ### Claim 13 A computer system for generating gesture-based computer commands, comprising: a processor configured to receive a video signal; identify pre-defined gestures in the video signal; and generate computer commands corresponding to the pre-defined gestures in the video signal. ### Claim 14 (depends on 13) The computer system according to claim 13 further comprising a storage device in communication with the processor, the storage device storing a gesture-recognition application comprising instructions to be executed by the processor for identifying pre-defined gestures in the video signal. ### Claim 15 (depends on 14) The computer system according to claim 14, wherein the gesture-recognition application further comprises instructions to be executed by the processor for generating computer commands corresponding to the pre-defined gestures in the video signal. ### Claim 16 (depends on 13) The computer system according to claim 13 further comprising a single camera for generating the video signal. ### Claim 17 (depends on 13) The computer system according to claim 13 further comprising a storage device in communication with the processor, the storage device storing an application. ### Claim 18 (depends on 17) The computer system according to claim 17, wherein the processor is further configured to transmit the computer commands to the application. ### Claim 19 (depends on 18) The computer system according to claim 18, wherein the application is a presentation program. ### Claim 20 (depends on 19) The computer system according to claim 19, wherein the processor is further configured to: identify a pre-registered user by facial recognition; and identify the pre-defined gestures in the video signal performed by the pre-registered user.
