Abstract
A detector detects the variation of resistance between fingers of a human's hands which varies in response to his mental condition. When the mental condition is varied and the resistance between fingers is changed, the detector detects such resistance variation, which is then converted into an electric signal. This electric signal drive light emitting diodes (LEDs) or the like so that the user of this detector can realize his mental condition by watching the light. By further providing a lamp, an image film and a lens, the user can watch the image on the image film when light radiated from the lamp projects such image onto the lens. This detector is useful for meditation and mental training because the user can realize the variation of his mental condition by watching the light or image.
