Abstract: A personal display device for displaying virtual images to a wearer. The personal display device includes a frame having a right temple section, a left temple section, a right rear section, a left rear section, a right eye see-through section, and a left eye see-through section; a projection display device connected to the frame for projecting an image to the wearer; at least one waveguide stack module connected to the frame for propagating image-bearing light beams along a length of the at least one waveguide stack module, the at least one waveguide stack module being configured to receive the image from the projection display device and detected touch motions of the wearer sensed by the touchpad including sensing directions of the touch motions of the wearer.

Abstract: A method of unlocking software including providing an electronic device having a processing unit and a gesture input device connected therewith. Detecting an input gesture operable to initiate password entry, wherein the electronic device is in a software locked state, and randomly assigning a predefined set of input gestures to a predefined set of password symbols. The method of unlocking software additionally includes detecting one of the assigned input gestures via the gesture input device and comparing the entered password symbols, corresponding to the detected input gestures, to a stored unlock password via the processing unit. Further, where the entered password symbols match the stored unlock password, the method enables operation of the electronic device in a software unlocked state.
