Method and apparatus enabling archery practice
First Claim
1. A method providing archery practice simulating an animal hunt, comprising the steps of;
- providing a video disk containing a plurality of scenes of animals in a natural environment,providing a vertical screen whose size simulates an area normally viewed by an archer during an animal hunt, said screen comprising a plurality of pixel areas arranged in a plurality of horizontal rows and vertical columns,providing a video projector spaced from one side of said screen,coupling said projector to said video disk and using said projector to project at least one of said hunting scenes onto said one side of said screen,providing a continuous full screen field of light of a spectrum that is not visible to a human, said field of light being spaced from but in close proximity to said one side of said screen,providing an arrow that is capable of reflecting light of said spectrum as the arrow penetrates said field of light,providing a detector that is sensitive to light of said spectrum and is not sensitive to a projected hunting scene, said detector being positioned to receive light reflected from an arrow as said arrow penetrates said field of light, and to then generate a signal corresponding to a pixel area of said screen, certain of which pixels areas contain indicia of light reflection from an arrow,freezing said hunting scene on said screen upon said detector detecting light reflection from an arrow, andcoordinating said frozen hunting scene to the signal from said detector and thereby projecting a hit zone image on said screen to indicate a point of arrow impact thereon.

Abstract
An archery practice device simulates dynamic targets, such as in an animal hunt, on a visible screen. A video disk contains a plurality of hunting scenes which are projected via a video projector on a vertical screen whose size simulates an area normally viewed by an archer during a hunt. The screen images are comprised of pixel areas arranged in horizontal rows and vertical columns. A source of light of a spectrum outside the humanly visible range is provided adjacent the screen. Arrows penetrating this light field reflect light to a detector sensitive to light of said spectrum, but not sensitive to visible light otherwise. The detector generates a full screen signal of a plurality of pixel areas, certain of which contain indicia of light reflection from the arrow. Upon detecting such reflection, the scene frame is frozen on the screen. The frozen frame is coordinated to the signal from the light detector, whereupon a hit zone image is projected to indicate an arrow impact point relative to the frame image to show the scoring of the point of arrow impact.

6. A method providing archery practice simulating a dynamic target scene as in an animal hunt, comprising the steps of;
-
projecting target scenes in sequence on a screen for viewing as a dynamic target by an archer, detecting an arrow hit at a hit location on said screen upon the occurrence of an arrow launched by said archer at a given scene, freezing said given scene on said screen for viewing by said archer upon detection of said arrow hit at said hit location on said screen, and projecting said hit location on said screen for viewing by said archer along with said frozen scene, with said arrow hit location visually indicated to said archer on said given scene as an indication of the accuracy of said arrow hit relative to said given scene. - View Dependent Claims (7, 8)

9. Apparatus for simulating a moving hunt scene for an arrow shot by an archer comprising
a screen having a vertical imaging plane, means projecting a sequence of visual frames comprising said moving hunt scene onto said vertical imaging plane for presenting at least one hunt object visible to the archer, means responsive to arrival of an arrow shot by an archer at said vertical imaging plane for sensing the coordinate location of said arrow on said plane, means responsive to said sensing means for comparing said arrow coordinate position with said hunt object within one of said visual frames that was present on said vertical imaging plane when said arrow arrived thereat, means for determining the accuracy of the arrival of said arrow relative to said hunt object presented by said one visual frame, means responsive to said sensing means for freezing said one visual frame on said screen for viewing by the archer, and means projecting said arrow coordinate position on said screen for viewing by the archer along with said one visual frame.

18. A method for providing archery practice by an archer, comprising the steps of;
-
providing a video disk containing a plurality of visual scenes, providing a reflection screen whose size simulates an area normally viewed by an archer, providing a video projector spaced from one side of said screen, coupling said projector to said video disk and using said projector to project at least one of said scenes onto said one side of said screen, providing a full screen sensing field in proximity to said one side of said screen, providing an arrow that is capable of being sensed as said arrow penetrates said sensing field, and providing a detector that is sensitive to an arrow penetrating said sensing field, said detector being operable to generate a signal corresponding to a zone of said screen corresponding to said arrow penetrating said sensing field. - View Dependent Claims (19, 20, 21)

22. Apparatus for visually providing a moving hunt scene toward which an arrow shot by an archer is directed, comprising:
-
a screen having an imaging plane, means projecting a sequence of visual scenes onto said imaging plane, said sequence of visual scenes presenting at least one moving arrow target, means responsive to arrival of an arrow shot by an archer at said imaging plane for sensing the arrival location of said arrow on said plane, means responsive to said sensing means for comparing said arrow arrival location with the position of said arrow target within one visual scene that was present on said imaging plane at the time of arrival of said arrow on said plane, means for determining the accuracy of said arrow arrival location relative to said arrow target position that was provided by said one visual scene, means responsive to said sensing means for freezing said one visual scene onto said imaging plane for viewing by an archer, and means projecting said arrow arrival location on said imaging plane along with said one visual frame. - View Dependent Claims (23, 24, 25)
