First Claim
Patent Images
1. An apparatus for aiding transmission of intent, comprising:
- displaying means for displaying a plurality of character patterns;
determining means for determining whether a signal level based on currents of a beta-wave frequency band of a brain wave exceeds a predetermined level;
control means for controlling said displaying means such that a character pattern available for selection is displayed distinguishably from the other character patterns;
changing means for sequentially changing the character pattern available for selection from one character pattern to another on said displaying means; and
selecting means, responsive to a determination by said determining means that the signal level based on currents of the beta-wave frequency band of the brain wave exceeds the predetermined level, for selecting the character pattern distinguishably displayed by said displaying means.

Abstract
An apparatus and a method for aiding the transmission of intent enables a severely physically-handicapped person, who has lost muscular energy due to amyotrophic lateral sclerosis (ALS), muscular dystrophy or the like, to transmit his/her intent through an electroencephalogram wave. A mechanical switch and an electroencephalogram wave switch are used in combination to allow the transmission of intent over the entire period of such a disease.

7. A method for aiding transmission of intent, comprising:
-
displaying a plurality of character patterns on a display device; determining whether a signal level based on currents of a beta-wave frequency band of a brain wave exceeds a predetermined level; controlling the display device such that a character pattern available for selection is displayed distinguishably from the other character patterns; sequentially changing the character pattern available for selection from one character pattern to another on the display device; and selecting, in response to a determination that the signal level based on currents of the beta-wave frequency band of the brain wave exceeds the predetermined level, the character pattern distinguishably displayed on the display device. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer-readable medium recording computer program for aiding transmission of intent, the computer program comprising:
-
a displaying module for displaying a plurality of character patterns on a display device; a determining module for determining whether a signal level based on currents of a beta-wave frequency band of a brain wave exceeds a predetermined level; a controlling module for controlling the display device such that a character pattern available for selection is displayed distinguishably from the other character patterns; a changing module for sequentially changing the character pattern available for selection from one character pattern to another on the display device; and a selecting module for selecting, in response to a determination that the signal level based on currents of the beta-wave frequency band of the brain wave exceeds the predetermined level, the character pattern distinguishably displayed on the display device.
