Abstract
A chair based interface comprising a lower portion attachable to the base of a two part chair and an upper portion attachable to the shaft of a two part chair. A rocker arm connects the two portions and depresses an internal switch when pressure is placed on the chair. A wireless transmitter and receiver and attached interface can control a computer or other device based on the activation or deactivation of the switch. The device can be integrated into or attached to a chair during manufacturing or attached after market.
