1. A method of controlling a head-mountable device for transmitting and receiving information from a human user with at least one eye, said device having a virtual display, at least one eye position tracking sensor, and connectivity to at least one touchpad;

  • said device comprising a frame configured to attach to the head of a user;

    wherein said connectivity to at least one touchpad is achieved by physically connecting said at least one touchpad to said frame, thereby becoming a head mounted touchpad, said method comprising;

    using at least one processor to display a plurality of visual targets on said virtual display, said plurality of visual targets each comprising a visual element area embedded within a visual element position zone with an area that is equal to or larger than said visual element area, thus producing a plurality of visual element areas, each visual element area and visual element position zone mapping to a touch sensitive touch element on a touchpad position zone;

    wherein at least some of said plurality of visual targets further comprise a visual element embedded within an eye position zone with an area that is equal to or larger than said visual element;

    using any of said at least one touchpad or said at least one eye position tracking sensor to register that a virtual key corresponding to said at least one of said plurality of visual targets has been pressed by said user by using said at least one eye position tracking sensor to determine when said at least one eye is on average continuously gazing in a direction that is within an eye position zone of at least one of said plurality of visual elements for a time period exceeding a hovering time interval, signaling when said hovering time interval has been exceeded, and if said gaze remains within the eye position zone of said at least one of said plurality of visual elements, without looking away, for a time period exceeding a keypress time interval, also registering that an eye gaze controlled virtual key corresponding to said at least one of said plurality of visual targets has been pressed by said user; and

    using said virtual key presses to control either transmitting or receiving said information to at least one computerized device outside of said head-mountable device'"'"'s said frame.
