Establishing a communication connection between two devices based on device displacement information

1. An information processing apparatus comprising:

an interface that receives, from another information processing apparatus, first displacement information;

a displacement sensor that senses second displacement information corresponding to movement of the information processing apparatus; and

a processor that

determines whether a second pattern corresponding to the second displacement information is the reverse of a first pattern corresponding to the first displacement information; and

controls the interface to establish a connection with the another information processing apparatus when it is determined that the second pattern is the reverse of the first pattern.

2. The information processing apparatus of claim 1 , wherein the processor determines that a predetermined motion is applied to the information processing apparatus based on an amount of movement sensed by the displacement sensor, and generates the second displacement information based on the determination.

3. The information processing apparatus of claim 1 , wherein the first displacement information corresponds to movement of the another information processing apparatus.

4. The information processing apparatus of claim 3 , wherein the first displacement information is included in a signal transmitted from the another information processing apparatus that notifies a presence of the another information processing apparatus.

5. The information processing apparatus of claim 4 , wherein the signal includes identification information corresponding to the another information processing apparatus.

6. The information processing apparatus of claim 5 , wherein the processor authenticates the another information processing apparatus based on the identification information corresponding to the another information processing apparatus when it is determined that the second pattern is the reverse of the first pattern.

7. The information processing apparatus of claim 6 , wherein the processor controls the interface to transmit, to the another information processing apparatus, identification information corresponding to the information processing apparatus based on a result of the authentication.

8. The information processing apparatus of claim 5 , wherein the signal includes display information instructing an operation of a user of the information processing apparatus to move the information processing apparatus.

9. The information processing apparatus of claim 8 , wherein the displayed information instructs the user to move the information processing apparatus in a direction that is reverse from a direction of the movement of the another information processing apparatus indicated by the first displacement information.

10. The information processing apparatus of claim 9 , wherein the processor authenticates the another information processing apparatus based on the identification information corresponding to the another information processing apparatus when it is determined that the second pattern is the reverse of the first pattern.

11. The information processing apparatus of claim 10 , wherein the processor controls the interface to transmit, to the another information processing apparatus, identification information corresponding to the information processing apparatus based on a result of the authentication.

12. The information processing apparatus of claim 1 , wherein the processor controls the interface to transmit, to the another information processing apparatus, the second displacement information.

13. The information processing apparatus of claim 12 , wherein the second displacement information is included in a signal transmitted from the information processing apparatus to the another information processing apparatus that notifies a presence of the information processing apparatus.

14. The information processing apparatus of claim 13 , wherein the signal includes identification information corresponding to the information processing apparatus.

15. A method performed by an information processing apparatus, the method comprising:

receiving, at an interface of the information processing apparatus, from another information processing apparatus, first displacement information;

sensing second displacement information corresponding to movement of the information processing apparatus;

determining, by a processor of the information processing apparatus, whether a second pattern corresponding to the second displacement information is the reverse of a first pattern corresponding to the first displacement information, and

controlling, by a processor of the information processing apparatus, the interface to establish a connection with the another information processing apparatus when it is determined that the second pattern is the reverse of the first pattern.

16. A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing apparatus, cause the information processing apparatus to:

receive, from another information processing apparatus, first displacement information;

sense second displacement information corresponding to movement of the information processing apparatus;

determine whether a second pattern corresponding to the second displacement information is the reverse of a first pattern corresponding to the first displacement information; and

control an interface to establish a connection with the another information processing apparatus when it is determined that the second pattern is the reverse of the first pattern.
