A planar touch control is used to provide input to a computer and haptic feedback is provided thereto. A touch control includes a touch input device with a planar touch surface that inputs a position signal to a processor associated with the computer based on a location of user implemented contact on the touch surface. The computer can position or modify a cursor or image in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user via the touch surface.

There is provided an optical device, having a light transmitting substrate (20) including at least two major surfaces parallel to each other and edges; optical means (16) for coupling light into the substrate by internal reflection and at least one reflecting, surface (22) located in the substrate which is non-parallel to the major surfaces of the substrate (20) characterized in that the optical means (16) for coupling light into the substrate is a partially reflecting surface, wherein part of the light coupled into the substrate (20) passes through the partially reflecting surface (16) out of the substrate and part of the light is reflected into the substrate (20).

There is provided an optical device, including a light-transmitting substrate having two major surfaces parallel to each other and two edges, optics for coupling light into the substrate by internal reflection. One of the edges is slanted with respect to the major surfaces and a portion of the optics for coupling light into the substrate is in contact with, or located adjacent to, the slanted edge.

There is provided an optical system, including a mechanical body (110), a light-transmitting substrate (20) having two major surfaces and edges, embedded in the mechanical body, an optical element (90) for coupling light into the substrate by total internal reflection and a plurality of partially reflecting surfaces (22) carried by the substrate, wherein the partially reflecting surfaces are parallel to each other and are not parallel to any of the edges of the substrate. The system also includes an image capturing device (112), a display source (4), and an image-processing unit (114). The image-capturing device (112) is connected via the image-processing unit (114) to the display source (4).

There is provided an optical device for transferring light within a given field-of-view, comprising an input aperture; reflecting surfaces, and an output aperture located in spaced-apart relationship from the input aperture such that light waves, located within the field-of-view, that enter the optical device through the input aperture, exit the optical device through the output aperture, wherein the reflecting surfaces are at least one pair of parallel reflecting surfaces and that part of the light waves located within the field-of-view that enter the input aperture, pass directly to the output aperture without being reflected off the at least one pair of parallel reflecting surfaces, while another part of the light waves within the field-of-view that enters the input aperture, arrives at the output aperture after being twice reflected by the at least one pair of parallel reflecting surfaces.

The present invention comprises a method, apparatus, and computer program product for providing a graphical user interface (GUI) with a linear map component. A database that includes data representing transportation segments and point of interest (POI) features is employed. Once the desired location is determined, the data relating to it is extracted from the database and presented to the user in a GUI in which individual transportation segments along the predetermined route or projected path of travel are shown in a linear format. The linear formatted segments are oriented vertically in the map display or printout in order to easily accommodate the display of textual information and / or links associated with POIs along the path of travel. Further information is displayed pursuant to user selection of links or icons in the main GUI screen.

This invention relates to an improved design for the transmit and receive optical elements of a waveguide-based optical touch screen sensor, where at least one converging lens is incorporated within the body of each transmit and receive element. The optical elements of the improved design are more mechanically robust, easier to incorporate into the touch screen assembly, and are less susceptible to stray light and the ingress of foreign matter. In one embodiment the converging lens collimates the light into a plane wave. In another embodiment the converging lens focuses the light to an external point. In yet another embodiment, each transmit and receive element also includes at least one diverging lens. The transmit and receive elements and associated waveguides preferably comprise photo-patternable polymers.

An optical device including a light waves-transmitting substrate having two major surfaces and edges, has optical means for coupling light into the substrate by total internal reflection, and a plurality of partially reflecting surfaces (22a, 22b) carried by the substrate. The partially reflecting surfaces (22a, 22b) are parallel to each other and are not parallel to any of the edges of the substrate. One or more of the partially reflecting surfaces (22a, 22b) is an anisotropic surface.

There is provided a light-guide, compact collimating optical device, including a light-guide having a light-waves entrance surface, a light-waves exit surface and a plurality of external surfaces, a light-waves reflecting surface carried by the light-guide at one of the external surfaces, two retardation plates carried by light-guides on a portion of the external surfaces, a light-waves polarizing beamsplitter disposed at an angle to one of the light-waves entrance or exit surfaces, and a light-waves collimating component covering a portion of one of the retardation plates. A system including the optical device and a substrate, is also provided.
