ABSTRACT:
A hand-held illuminated presentation pointer is described. In a lighted room, the pointer has all of the advantages of a conventional pointing rod. In a darkened room, the pointer can be illuminated so that it emits light from just one side of the shaft. When used in conjunction with a projected image such as from a 35 mm slide, the pointer is held so that illuminated side of the shaft faces the audience, with the result that the pointer is clearly visible as a glowing line in front of the projected image, and yet the appearance of the image is unaffected. Smaller illuminated pointers for use at close range are also described.
