Abstract

A gesture input method includes: observing a wrist; outputting state information indicating a state of the wrist; determining, by a processor, according to the state information whether the wrist is in a dorsiflexion state; and performing, by the processor, a predetermined process in accordance with whether the wrist is in the dorsiflexion state.

Claims

1. A gesture input method comprising:

observing a wrist;

outputting state information indicating a state of the wrist;

determining, by a processor, according to the state information whether the wrist is in a dorsiflexion state; and

performing, by the processor, a predetermined process only when the wrist is in the dorsiflexion state, wherein

the dorsiflexion state is a state in which the wrist is bent outward.

2. The gesture input method according to claim 1, further comprising:

receiving, by the processor, a gesture of a hand including the wrist; and

performing, by the processor, a control corresponding to the gesture when the wrist is in the dorsiflexion state.

3. The gesture input method according to claim 2, further comprising:

when the wrist is in the dorsiflexion state, making a report that the wrist is in the dorsiflexion state.

4. The gesture input method according to claim 1, further comprising:

observing a hand; and

outputting configuration information indicating a configuration of the hand, wherein

the determining determines the configuration of the hand according to the configuration information, and

the performing of the predetermined process performs the predetermined process according to the configuration of the hand and according to whether the wrist is in the dorsiflexion state.

5. The gesture input method according to claim 1, wherein

the determining determines according to the state information whether the wrist is in a palmar flexion state, and

the performing of the predetermined process performs the predetermined process according to whether the wrist is in the dorsiflexion state and whether the wrist is in the palmar flexion state.

6. The gesture input method according to claim 1, further comprising:

measuring a posture of a hand or an external force applied to the hand; and

outputting limitation information indicating the posture or the external force, wherein

the determining determines according to the limitation information whether the wrist is in the dorsiflexion state.

7. A gesture input method comprising:

observing a wrist;

outputting state information indicating a state of the wrist;

determining, by a processor, according to the state information whether the wrist is in a palmar flexion state; and

performing, by the processor, a predetermined process only when the wrist is in the palmar flexion state, wherein

the palmar flexion state is a state in which the wrist is bent inward.

8. A gesture input method comprising:

observing an ankle;

outputting state information indicating a state of the ankle;

determining, by a processor, according to the state information whether the ankle is in a plantar flexion state; and

performing, by the processor, a predetermined process only when the ankle is in the plantar flexion state, wherein

the plantar flexion state is a state in which the ankle is bent outward.

9. A gesture input method comprising:

observing lips;

outputting state information indicating a state of the lips;

determining, by a processor, according to the state information whether the lips are in a rolled inward state; and

performing, by the processor, a predetermined process only when the lips are in the rolled inward state, wherein

the rolled inward state is a state in which an upper lip and a lower lip of the lips are rolled into a mouth.
