recognize that a transition has occurred between the first state and the second state,
recognize a user context according to the recognized transition, and
perform a control of the information processing apparatus according to the user context,

wherein the circuitry is further configured to
recognize the first state in which the arm is raised and held in front of a body of the user and the second state in which the arm is held close to an ear of the user, and
recognize the user context which the user answers a call according to the transition between the first state and the second state in a call state.

2. The information processing apparatus according to claim 1 ,
wherein the circuitry performs the control of the information processing apparatus by controlling at least one selected from a group consisting of a display unit, an operation unit, a motion sensor, a speaker, a microphone, and an imaging unit.

3. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to determine whether the information processing apparatus is worn on a right arm or a left arm of the user.

4. The information processing apparatus according to claim 3 ,
wherein the circuitry is further configured to determine whether the information processing apparatus is worn on the left arm or the right arm, on the basis of motion detected by the motion sensor.

5. The information processing apparatus according to claim 3 ,
wherein the circuitry is further configured to determine whether the information processing apparatus is worn on the left arm or the right arm, by mechanical learning using values acquired by the motion sensor.

6. The information processing apparatus according to claim 3 ,
wherein the circuitry is further configured to determine whether the information processing apparatus is worn on the left arm or the right arm, on the basis of a user input.

7. The information processing apparatus according to claim 3 ,
wherein the circuitry is further configured to switch a setting of a parameter for recognition of the transition, based on whether the information processing apparatus is determined to be worn on the right arm or the left arm of the user.

8. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to
recognize the first state in which the arm is raised and held in front of a body of the user and a third state in which the arm is lowered, and
recognize the user context which the user does not answer a call according to the transition between the first state and the third state in a call state.

9. The information processing apparatus according to claim 8 ,
wherein the circuitry is further configured to perform a control to send a message to an information processing terminal of another side of the call and end the call, according to the user context.

10. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to perform a control to start a call, according to the user context.

11. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to
recognize the second state in which the arm is held close to an ear of the user and the first state in which the arm is raised and held in front of a body of the user, and
recognize the user context which the user checks a display and continues a call according to the transition between the second state and the first state in a call state.

12. The information processing apparatus according to claim 11 ,
wherein the circuitry is further configured to perform a control to increase an output of a speaker and switching on a touch sensor, according to the user context.

13. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to
recognize the first state in which the arm is raised and held in front of a body of the user and a fourth state in which the arm is rotated in front of the body, and
perform a control of returning the display to a previous screen or proceeding to a next screen according to the transition between the first state and the fourth state.

14. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to
recognize the first state in which the arm is raised and held in front of a body of the user and a fifth state in which a camera is held in a shooting position, and
perform a control to switch on the camera according to the transition between the first state and the fifth state.

15. The information processing apparatus according to claim 14 ,
wherein the circuitry is further configured to
recognize the fifth state in which the camera is held in the shooting position and a sixth state in which the information processing apparatus is swung, and
perform a control to switch a mode from image shooting to moving image shooting according to the transition between the fifth state and the sixth state.

16. The information processing apparatus according to claim 1 ,
wherein the circuitry is further configured to perform a control of at least one of a plurality of sensors according to the recognized transition.

17. The information processing apparatus according to claim 1 ,
wherein the circuitry performs the control to optimize the information processing apparatus by turning off at least one function of the information processing apparatus according to the user context.
