Abstract: A computer input device. The device is a body containing at least one tube. There is a first conductor in the tube able to move along the tube. Spaced contacts are formed within the tube and conductors extend from the spaced contacts. First interfaces receive information from the conductors as to the position of the first conductor in the tube and input information to the computer based on the position of the first conductor. Second interfaces input information to the computer.
