Abstract

An input system executes an input to an information processing apparatus depending on the hand motion. Plural myoelectric sensors are provided on an area between a wrist of the person and bases of a second finger to a fifth finger, and detect myoelectric signals depending on the hand motion. A setting portion outputs at least one command to make the person execute at least one particular motion in a state where the myoelectric sensors are worn on the hand, and associates the detected myoelectric signals after the output of the command with the particular motion corresponding to the command. An input portion identifies the hand motion from myoelectric signals detected based on the hand motion after the termination of the association and the association result of the setting portion, and executes the input to the information processing apparatus depending on the identified hand motion.

Claims

1. 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 an area between a wrist of the person and bases of a second finger to a fifth finger, and detect 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, and associates the myoelectric signals detected by the plurality of myoelectric sensors after the output of the command with the particular motion corresponding to the command; and

an input portion that identifies the hand motion from myoelectric signals detected by the plurality of myoelectric sensors based on the hand motion of the person after the termination of the association by the setting portion, and the association result of the setting portion, and executes the input to the information processing apparatus depending on the identified hand motion.

2. The input system as claimed in claim 1, wherein the setting portion extracts time-series characteristic master data from the myoelectric signals detected by the plurality of myoelectric sensors, and associates the extracted time-series characteristic master data with the particular motion, and

the input portion extracts time-series characteristic data from myoelectric signals detected by the plurality of myoelectric sensors based on the hand motion of the person after the termination of the association by the setting portion, and identifies the hand motion from the extracted characteristic data and the association result.

3. The input system as claimed in claim 1, further comprising a main body portion that maintains the plurality of myoelectric sensors at preset positions, and is shaped or is substantially shaped in a form of annulus.

4. The input system as claimed in claim 3, wherein the main body portion is provided with an output portion outputting the command from the setting portion.

5. The input system as claimed in claim 1, wherein the command from the setting portion includes a command recognized through the sight of the person.

6. The input system as claimed in claim 1, wherein the command from the setting portion includes a command recognized through the hearing of the person.

7. The input system as claimed in claim 1, wherein the input from the input portion to the information processing apparatus is executed by wireless communication.

8. An input apparatus executing an input to an information processing apparatus depending on the hand motion of a person, comprising:

a main body portion that is shaped or is substantially shaped in the form of annulus and is worn so as to surround the palm and the back of a hand of the person in a state where the hand of the person from a second finger to a fifth finger is inserted into the main body portion; and

a plurality of myoelectric sensors that are provided on the main body portion, and detect myoelectric signals depending on the hand motion of the person.

9. The input apparatus as claimed in claim 8, wherein the plurality of myoelectric sensors are disposed in at least palm side of the hand.
