Abstract:
1. A portable display device comprising: an optically transparent sheet comprising an electrically conductive layer; an electrode element; electro-vibration circuitry connected to the electrically conductive layer and the electrode element, where the electro-vibration circuitry is configured to provide a time-varying voltage signal across the electrically conductive layer, a body of a user, and the electrode element so as to cause a user to experience electro-vibration in a first body part of the user when the first body part is moved across an exterior surface of the optically transparent sheet while a second body part of the user is in contact with the electrode element; and a display panel having a display surface, the display panel being configured to display images to a user via the display surface, wherein the optically transparent sheet is arranged to overlie at least a portion of the display surface.
