Patent ID: 8704757

Claim:
An input system executing an input to an information processing apparatus depending on the hand motion of a person, comprising: a plurality of myoelectric sensors that are provided on a hand of the person in an area between a wrist of the person and bases of a second finger to a fifth finger, and output myoelectric signals depending on the hand motion; a setting portion that outputs at least one command to make the person execute at least one particular motion using the hand in a state where the plurality of myoelectric sensors are worn on the hand; one or more processors configured to: perform a sensor calibration subroutine of detecting and storing initial output myoelectric signals for each of the myoelectric sensors for a predetermined period of time in which the hand of the person is maintained in a constant posture; and when the setting portion outputs a command including a message that represents the input, the message indicating a motion to be made by the hand of the person, perform an associative subroutine of detecting output myoelectric signals for each of the myoelectric sensors for a predetermined period of time in which the motion is made by the hand of the person, calculate first difference signals indicative of a difference between the detected output myoelectric signals and the initial output myoelectric signals, extract time-series characteristic master data of the myoelectric sensors from the first difference signals, associate the time-series characteristic master data of the myoelectric sensors with the motion, and store a result of the association; and an input portion that identifies the hand motion from second difference signals calculated depending on the myoelectric signals output by the plurality of myoelectric sensors based on the hand motion of the person after termination of the associative subroutine, and executes the input to the information processing apparatus depending on the identified hand motion.
