ABSTRACT:
An input device and keyboard for a computer. The input device includes controls that receive commands from a user and transmit the commands to the computer via a communication link. In one embodiment, the controls include an input button which is elongated and contoured to engage a relatively large portion of the user's finger. The input button may also be curved and/or canted so as to support the user's finger in an ergonomic position. In another embodiment, the input device may be housed within an opening in the keyboard and may be detached from the keyboard by removing it from the opening. The input device may be operated when either attached to or detached from the keyboard. In still another embodiment, right and left input devices are removably attached to the keyboard and may be operated with the user's right and left hands, respectively.
