Abstract: A hand held data entry controller includes a chassis having a handle portion which is shaped to fit in the user's hand, and a cursor controller, such as a track ball, attached to the chassis for providing a signal representative of a desired cursor position on a display screen. In another embodiment, the data entry device further includes at least one command button for providing a command signal representative of a desired command. The data entry device may also include a microphone attached to the chassis for providing an acoustic speech signal representative of a user's speech. In this embodiment, the device may also include a voice command button, attached to the chassis, for providing, in response to a user's input, a command signal indicating whether the acoustic speech signal represents a spoken command.
