NPointer

Computer control with simple hand gestures near a webcam and voice commands. The freeware app provides gestural and vocal computer control and navigation by emulating the actions usually performed with a mouse or touchpad: pointer movement, clicks, double-clicks, drags and scrolls. Works on Microsoft Windows with regular and laptop webcams. Voice commands may be used with the regular pointer control with mouse, touchpad, keyboard or other accessibility options. Disabled people may also use head movements for added accessibility. Does not require installation.
