ABSTRACT:
A device to determine which target a participant has selected during simued weapon training is disclosed. The device uses a second projector in addition to the computer generated image projector to project a non-visible light onto a screen. The computer generated imagery projector and the non-visible light projector are adjusted to create a composite image, visible and non-visible, projected on the screen such that the non-visible image is overlaid on the visible image at all times. The non-visible image contains information related only to certain pre-defined targets. The participant is able to sense the visible portion of the image on the screen but not the non-visible image, which is reflected from the screen to an electronic sensor that senses only the non-visible image. A computer processes the information obtained from the sensor to determine which target the participant has selected.
