Inexpensive semiconductors are produced by depositing a single crystal or large grained silicon on an inexpensive substrate. Each heat strip comprises a plurality of triangular-shaped assemblies having a heat cable inserted from under the assemblies and positioned adjacent to a notched front panel. An electrode in contact with a user’s skin receives the electrical muscle stimulation current, causing a haptic effect by contraction and relaxation of muscles near the electrode. The parameter is stored by the video game and changes an attribute of the video game. A drive mechanism may be provided is for selectively displacing the grippers from the first position to the second position to adjust the spacing between the grippers.
