An interactive display system including a wireless pointing device including a camera or other video capture system. The pointing device captures images displayed by the computer, including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. The location, size, and orientation of the recovered positioning target identify the aiming point of the remote pointing device relative to the display. Another embodiment uses temporal sequencing of positioning targets (either human-perceptible or human-imperceptible) to position the pointing device.

A virtual three-dimensional presentation in accordance with the present invention includes three stereoscopic layers, a stereoscopic background layer, a stereoscopic video insert layer, and a stereoscopic three-dimensional foreground layer. A surface, the Z-sphere, is defined in the virtual three-dimensional space of the three-dimensional scene with reference to the aim point, the distance between the cameras, and the distance from the camera of the video scene, of a virtual stereoscopic camera looking at the three-dimensional scene being created. The separation of the virtual stereoscopic camera lens and distance to the aim point are set based on the stereoscopic cameras that are creating the video insert layer. The stereoscopic three-dimensional foreground layer scene may include a key which defines the transparency of objects in the foreground layer. The stereoscopic video insert layer may be generated by positioning a presenter, or other object, in a chroma-key set which is captured with a stereoscopic camera. The stereoscopic video insert layer may be distorted before being composited with the background and foreground such that elements of the stereoscopic video appear to move across a three-dimensional floor of the stereoscopic three-dimensional scene.

A gunsight reticle defines a system of dimensioned indicia spaced at specific separations to improve aiming accuracy of a gun. The indicia may include perpendicularly intersecting center vertical and center horizontal hairlines, and four (or more or less) horizontal range-marker lines disposed at specific angular separations below the horizontal hairline in bisected relationship with the center vertical hairline. Spacing of the range marker lines below the center horizontal hairline is proportional to bullet drop at selected ranges, depending upon ballistic characteristics of bullet used. Relative lengths of said range-marker bars on each side of the central vertical crosshair are proportional to a specific crosswind (say 10 mph) at target range reflected by respective range marker. The method involves employing this reticle to determine distance to target, and using distance thus determined to ascertain a precise aiming point on the reticle. These indicia also have other useful characteristics that allow the shooter to easily mentally calculate corrections for crosswind, moving targets and shooting at targets that are above or below the shooter at a significant angle.

A sighting system for visually acquiring a target includes an optic device having a transmissive LCD array affixed thereon. The transmissive LCD array includes two or more LCD elements that are separately addressable to provide an aiming point. In embodiments, the sighting system receives information from an input system, such as ammunition information or environmental information, executes a ballistics program to determine ballistics information using the received information, and determines a range to the target. A controller calculates an aiming point using the ballistics information and the target range. The controller then addresses or energizes one of the LCD elements to provide the aiming point.
