Abstract
Abstract A remote control device includes a motion detection circuit operative to generate signals indicative of a direction of movement of the device. A processor receives the signals from the motion detection circuit and generates corresponding control signals suitable for transmission to a receiver. A user is thereby able to indicate entry of particular commands by moving the remote control device in a certain way. For example, movement of the remote control device in a particular direction in a first plane may correspond to an up command for a first controlled parameter, e.g., receiver volume, while movement of the remote control device in an opposite direction in the first plane corresponds to a down command for the first controlled parameter. Similarly, movement of the remote control in a particular direction in a second plane perpendicular to the first plane may correspond to an up command for a second controlled parameter, e.g., channel selection, while movement of the remote control device in an opposite direction in the second plane corresponds to a down command for the second controlled parameter.
