Abstract: Methods and systems are disclosed relating to variable user tactile input device with display feedback to guide the user to the keys that the user may want to depress. The display feedback may highlight the keys that are being hovered over but not yet selected for writing to the application window so that the user may ensure that the correct keys are selected to be written to the application window. The variable user tactile input device with display feedback may be a keyboard system with tactile feedback and a virtual keyboard display system that may provide a view of the user tactile input device to the user while using a heads up display (HUD). The invention may provide a user with an input system that may be programmable to be a virtual pad such as a virtual keyboard, a virtual game controller, a virtual number pad and any other user tactile input device that the user may intend to use.

Abstract: Methods and systems are disclosed for controlling the focus depth of a 2D projected image on a pixel by pixel basis or on a region by region basis to create a 3D projected image that may be used for a heads up display (HUD) for augmented reality applications. The 3D projected image may be overlaid or combined with a 3D real world view using multiple reflective LCD arrays. The multiple reflective LCD arrays may receive a 2D projected image and may generate different length optical paths that may add depth to the 2D projected image to create a 3D projected image. The 3D projected image may be combined with the real world 3D image to create a 3D image encompassing a real world image and a 3D projection image that looks real and contains depth within the image.

Abstract: Methods and systems are disclosed for using a head-mounted display that may consist of an image projector mounted to the head that projects one or more images onto a screen in front of one or both of the user's eyes. Moreover, head-mounted displays may also include electronics to track the position of the user's head. This tracking information can then be used as an input to change the display projected to the user—creating a Virtual Realty environment. Head tracking may be combined with transparent or semi-transparent display screens, to enable a user to see both a projected image and the physical world beyond the display screen. In certain embodiments, tracking information may be used to adjust the location of a projected image to compensate for the detected head movement.

Abstract: Methods and systems are disclosed for integrating LC circuits into a user's jewelry for controlling systems such as computer games. The resonant frequency of the circuit at each of multiple rings worn by the user may be adjustable. A secondary coil within each ring may be moved in relation to the magnetic field generated by a primary coil that may be part of another piece of jewelry, such as a watch or a bracelet, to generate control signals. The magnetic field may inductively couple and power the rings, which may each contain an LC tank circuit. If powered, each of these circuits may oscillate at its resonant frequency. A receiver system may comprise an antenna and a tuning circuit to detect a resonant frequency as an input to control moves of a character within a game, for example for use with heads-up displays (HUDs) for augmented reality applications.

Abstract: Methods and systems relating to providing a mechanism that allows for providing a camera image picture, either still or video, to have the same line of sight as the eye without adding compensation circuitry, or substantial weight, size or power to a heads up display (HUD) for augmented reality applications. The camera may view the same image picture perspective as the eye sees by generating a second image picture view that may have the same line of sight as the eye using a beam splitter to split the incoming view before the image picture is viewed by the eye and the camera. In certain embodiments, after the image picture is split by the beam splitter, the image picture travels towards the eye and towards a camera that is operatively connected to a waveguide so that the image picture may propagate to the camera.
