Abstract:
1. A method for controlling the functionality of control elements of a control device, comprising: measuring, in a magnetometer of the control device, an orientation of the control device with respect to a magnetic reference point; storing a set of instructions in a non-transitory storage medium of the control device; receiving, in a processing unit of the control device, data from the magnetometer; determining, in the processing unit, whether the control device is oriented in a first zone or a second zone, wherein the first and second zones are defined with respect to the magnetic reference point and oriented relative to a controlled device associated with the control device by executing the set of instructions and based on the data received from the magnetometer; enabling a first set of control elements of the control device when the control device is oriented in a first zone; and disabling the first set of control elements of the control device when the control device is oriented in a second zone.
