Abstract
A low-cost miniature joystick pointing device with improved performance, which may be mass produced from a small number of component parts, and which lends itself to production by automated machinery. An inner conductive contact is disposed inside of and surrounded by one or more outer contacts where deflection of the inner or outer contact results in a measurable resistance which may be interpreted by analog to digital or RC timing circuitry to produce speed and directional output.
