ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates generally to data entry into a computer.
An operator of a computer typically enters data into a computer by typing the data on a keyboard attached to the computer. Some computers also include a microphone which provides the computer with an electrical representation of a user's voice. Such computers may include voice recognition software for converting the electrical representation of the user's voice to text. See for example, U.S. Pat. No. 5,036,539 entitled “Real Time Speech Processing Development System”; and U.S. Pat. No. 5,005,203 entitled “Method Of Recognizing Continuously Spoken Words”, both of which are incorporated herein by this reference.
The object of the present invention is to provide an improved data entry device.
SUMMARY OF THE INVENTION
In general, the invention relates to a handheld data entry controller. The 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.
This device allows the user to enter data and commands to a computer using a convenient hand held device. Other objects, features and advantages of the invention are apparent from the following description of preferred embodiments taken together with the drawings.
