(Operation of information processing device)
Next, the operation of the present embodiment will be described by dividing it into (1) basic operation, (2) elevator movement determination operation, and (3) current floor calculation operation.

(1) Basic operation First, the user 2 carries the information processing apparatus 1 and performs various activities. As an example of the activity, the user 2 moves horizontally such as walking or moves up and down using the elevator 30 while the information processing apparatus 1 is placed in a chest pocket of a shirt worn by the user.

  The acceleration sensor 12 of the information processing apparatus 1 detects acceleration generated in the information processing apparatus 1 as the user 2 moves.

(2) Elevator Movement Determination Operation FIG. 4 is a flowchart showing an example of the operation of the information processing apparatus 1.

  First, the sensor signal acquisition unit 100 acquires acceleration information detected by the acceleration sensor 12 (S1).

  Next, the gravitational direction acceleration calculating unit 101 determines the gravitational direction by, for example, integrating the triaxial acceleration information acquired by the sensor signal acquiring unit 100, and calculates the gravitational direction acceleration (S2).

  Next, the elevator movement determination unit 102 determines whether or not the elevator 30 has moved up and down from the acceleration in the gravity direction calculated by the gravity direction acceleration calculation unit 101 (S3). Below, the specific example of the determination method is shown.

  FIGS. 3A and 3B are graphs for explaining an example of the operation of the elevator movement determination method.

FIG. 3A is a graph with the acceleration in the gravitational direction detected by the acceleration sensor 12 as the vertical axis and time as the horizontal axis. As an example of the elevator movement, the user 2 and the information processing apparatus 1 “6F”. floor 3 ₃ corresponding from the floor 3 ₆ "3F" corresponding to "show a change in the acceleration in the direction of gravity when moving in the elevator 30.

The acceleration in the direction of gravity is 9.8 m / s ² before starting movement (50-54 seconds) and after moving (after 65 seconds), and 9.8 m / s during movement (54-65 seconds). s ² changes to the negative side and the positive side as a reference.

This changes to the negative side until the elevator 30 leaves the floor 36 and reaches the descending speed, and becomes 9.8 m / s ² while maintaining the descending speed. This is because it changes to the positive side until it decelerates and stops descending.

  That is, while moving by the elevator 30, the acceleration in the gravity direction changes in the negative and positive order when descending, and the acceleration in the gravity direction changes in the positive and negative order when rising, so the elevator moves The determination means 102 determines that there has been a descent or ascending elevator movement when detecting these acceleration changes.

  The elevator movement determination means 102 determines that the acceleration in the direction of gravity continues to deviate by a predetermined value or more based on the acceleration of gravity for a predetermined period (either 54-57 seconds or 60-65 seconds). It may be determined that the elevator has moved in the case of detecting a change in acceleration. Further, it may be determined that the elevator has moved when the change in acceleration during the predetermined period is equal to or less than a predetermined value.

(3) Current Floor Calculation Operation Next, the position information acquisition unit 103 acquires the current position information of the information processing apparatus 1 from the GPS sensor 13 (S4).

Next, the building information acquisition unit 104 acquires building information corresponding to the position information from an external building information server via the communication unit 14 based on the position information acquired by the position information acquisition unit 103 (S5). . Building information, for example, has information of difference in height of each floor 3 ₁ -3 ₇ height or each floor 3 ₁ -3 _7, the height difference is assumed to be 3m here. The building information may be acquired in advance.

  Next, the moving floor number calculating means 105 calculates the moving distance in the gravity direction, that is, the height change based on the acceleration in the gravity direction calculated by the gravity direction acceleration calculating means 101 (S6), and refers to the building information. The number of moved floors is calculated (S7). A specific example of the calculation method is shown below.

The moving floor number calculating means 105 calculates the moving distance as 9 m by double integration of the acceleration in the gravity direction (9.8 m / s ^{2 based} on zero) in FIG. Since the difference is 3 m, the number of moving floors is calculated as -3 floors. In order to calculate the movement distance more accurately, the acceleration may be double-integrated after removing noise of acceleration in the direction of gravity. Moreover, it is good also considering only the time slot | zone (54-65 second, or 54-57 and 60-65 second) determined that there was elevator movement as the time range which removes noise.

Next, the current floor calculation means 106 acquires the floor before movement from the current floor information 111 stored in advance. Here, it is assumed that has acquired the floor 3 ₆ corresponding to "6F".

Next, the current floor calculation unit 106, "3F current floor based on the floor 3 ₆ corresponding to" 6F "before transfer floor number transfer floor number calculation unit 105 is moved and the calculated" -3 floor " calculating a floor _{3 3} corresponding to "(S8), and updates the current floor information 111 (S9).

  By executing steps S6 to S9 described above at predetermined intervals, a change in height with time can be obtained as shown in FIG.

  The current floor calculation means 106 acquires from the shared schedule information the behavior details predicted by the user 2 in the time zone determined to have moved by the elevator in step S3 and the floor before the movement. The floor may be estimated. The schedule information is, for example, a meeting, going out, a break, etc., and the behavior predicted by the user 2 from the schedule information includes moving to a conference room, moving to the entrance floor, moving to a cafeteria or a store, etc. The estimated current floor is the floor where the conference room is located, the entrance floor (1F), the floor where the dining room and the shop are located.

  Next, the current floor information output unit 107 outputs the current floor information 111 to an external server or the like via the communication unit 14.

(Effect of embodiment)
According to the above-described embodiment, when the acceleration change in the gravity direction in the positive / negative direction appears in the acceleration information obtained from the acceleration sensor 12, it is determined that there has been an up-and-down movement. Movement can be determined.

  In addition, a change in height can be calculated from a change in acceleration information, and the number of moving floors can be calculated based on building information without acquiring altitude information. Furthermore, based on the floor information before moving and the number of moving floors, it is possible to sequentially update the current floor information 111 where the user 2 is located without acquiring altitude information.
