Myoelectric and wireless technologies are used for the control of a portable electronic device, such as a cellular telephone or a personal digital assistant (PDA). That is, a portable electronic device has a wireless myoelectric user interface. An apparatus includes a material which forms a forearm or wrist band, myoelectric sensors attached to the band, a digital processor coupled to the myoelectric sensors, and a wireless transmitter coupled to the digital processor. The apparatus is operative to sense and detect particular hand and/or finger gestures, and to broadcast control signals corresponding to the gestures for operative control of the portable electronic device.
