Abstract
An accessory for a computer includes two pneumatically activated flexible bulbs, hermetically connected by flexible tubing. One of the bulbs is attached to a switch on an input device for the computer, while the other bulb is remote from the input device. Compression of the remote bulb results in a flow of air to the other bulb, thus activating the switch. The resultant remote activation of the switch permits the user to operate the input device while avoiding repetitive movements causing injury to the user's hand.
