Biological feedback detection device, biological sensation expansion device, biological sensation expansion method, and computer program product

A biological sensation expansion device comprising:

• a memory that stores executable components;
• and
• a processor that executes executable components stored on a memory, the executable components comprising:
• a first stimulating unit that stimulates a tactile sensation in a first body part of a biological object;
• a second stimulating unit that stimulates a tactile sensation in a second body part of the biological object;
• a first stimulus sensation intensity measuring unit that measures a first stimulus sensation intensity indicating intensity of sensation of a stimulation felt in the first body part;
• a second stimulus sensation intensity measuring unit that measures a second stimulus sensation intensity indicating intensity of sensation of a stimulation felt in the second body part;
• a stimulation intensity ratio calculating unit that calculates a ratio regarding whether the second stimulus sensation intensity corresponds to a stimulation applied to the first body part or corresponds to a stimulation applied to the second body part;
• and
• a training unit that,
• in response to determining that, for the second stimulus sensation intensity, a rate of sensation intensity occurring due to the stimulation applied to the first body part is equal to or less than a threshold value, performs control to maintain intensity of a stimulation applied by the first stimulating unit and a stimulation applied by the second stimulating unit, and
• in response to determining that, for the second stimulus sensation intensity, the rate of the sensation intensity occurring due to the stimulation applied to the first body part exceeds the threshold value, performs control to maintain intensity of the stimulation applied by the first stimulating unit, and to reduce at least one of intensity or frequency of the stimulation applied by the second stimulating unit and to enhance stimulus sensation intensity occurring in the second body part due to a tactile stimulation applied to the first body part by the first stimulating unit.
