A ouija board modified by the addition of a little round hollow box with a pointer protruding from it. The hollow box is a miniature cabinet that is believed to accumulate psychic force as it moves under the fingers over a polished board printed with the alphabet.
The term autoscope has been given to such devices as the ouija board, planchette, and additor, that are believed to facilitate the production of messages from an unknown intelligent source, at times the subconscious mind, at other times from discarnate spirits of the dead.
