Eyeglasses nose piece switch
Eyewear or other head-worn apparatus are fitted with an activation accessory that includes one or more switch elements integrated with or attached to a nose piece of the eyewear. The switch elements are communicably coupled to a processor-based controller so as to provide input signals to the controller responsive to wearer-initiated activations of the switch elements through interaction with a frame or temple piece of the eyewear. Upon receipt, the controller evaluates the input signals to determine whether or not they represent a command for the controlled device by assessing the input signals for a signal pattern indicative of such a command, and then, if the evaluation determines that the input signals do represent the command, issues the command to the controlled device. Otherwise the controller proceeds to receive and evaluate further input signals from the switch elements in a like manner as the first input signals.

An activation accessory for eyewear, comprising one or more switch elements integrated with or attached to a nose piece of the eyewear, the one or more switch elements each communicably coupled to a controller configured to receive first input signals comprising a temporal or patterned sequence of inputs from the one or more switch elements responsive to wearer-initiated activations of the one or more switch elements, said one or more switch elements activated by a wearer pressing on a portion of a frame or temple piece of the eyewear while the eyewear is being worn by the wearer, evaluate the temporal or patterned sequence of inputs of the first input signals to determine whether or not they represent a command for a controlled device by assessing the first input signals to determine whether the temporal or patterned sequence of inputs are a signal pattern representative of said command, and to issue said command to the controlled device when said evaluation determines that the temporal or patterned sequence of inputs of the first input signals do represent said command, or otherwise to receive and evaluate further input signals from the one or more switch elements by assessing the further input signals for the temporal or patterned sequence of inputs representative of said command when said evaluation determines that the temporal or patterned sequence of inputs of the first input signals do not represent said command.
