<Description of notification method>
FIG. 4 shows an explanatory diagram of a notification pattern and notification setting information of an electronic device which is an embodiment of the notification method performed in the present invention.
FIG. 4A shows an example of the notification pattern.
Here, it is assumed that the user normally possesses both the information processing apparatus 1 and the electronic device 2, and shows a notification pattern regarding a state in which one of them is misplaced and a state in which both are misplaced. ing.
As shown in FIG. 4A, there are four notification patterns depending on the combination of “possession” and “missing” of both devices.
First, Pattern 1 shows a case where one user has the information processing apparatus 1 and the electronic device 2.
In this case, since both devices are owned by the user, it is considered that the distance between the two devices is quite close and there is no need for notification, and the electronic device 2 does not perform notification.

Pattern 2 shows a case where the user has the information processing apparatus 1 but the electronic device 2 has been misplaced somewhere.
In this case, if it is detected that the distance between the information processing device 1 and the electronic device 2 is greater than or equal to a predetermined distance, the electronic device 2 notifies the alarm using the first notification means. For example, the first notification means is a speaker and notifies by sound output from the speaker. However, as will be described later, the notification method varies depending on whether or not the electronic device 2 is stationary.

Pattern 3 shows a case where the user has the electronic device 2 but has left the information processing apparatus 1.
In this case, if it is detected that the distance between the information processing apparatus 1 and the electronic device 2 is greater than or equal to a predetermined distance, the electronic device 2 issues a warning using the second notification means. Here, the 2nd alerting | reporting means is a vibrator, for example.
Since the electronic device 2 is possessed by the user, for example, if the user is moving, it is detected that the electronic device 2 is not stationary, and the vibrator is activated to vibrate the electronic device body. , Alert you.

Pattern 4 shows a case where both the information processing apparatus 1 and the electronic device 2 are left behind.
In this case, the user does not have both, but if both are present nearby, no notification is performed.
However, if only one of the information processing apparatus 1 and the electronic device 2 that has been misplaced is moved by a third party, it can be in the state of the pattern 2 or the pattern 3, and therefore either one corresponding to the pattern Will be notified.
In the flowchart of FIG. 3 to be described later, notification processing in the case of pattern 2 and pattern 3 in FIG.

4B to 4D show an embodiment of the notification setting information 26 stored in the storage unit 25. FIG.
As the notification setting information 26, the distance threshold as shown in FIG. 4B, the notification pattern set by the discrimination distance and the stationary state shown in FIG. 4C, and the notification method shown in FIG. A list is preset.
However, the information is not limited to this.

As described above, the distance threshold is a distance used when the separation determination unit 27 determines whether the distance between the information processing apparatus 1 and the electronic device 2 is short or long.
Here, the distance threshold is set to 10 m, but the present invention is not limited to this.
For example, when the distance threshold is set to 10 m, if the estimated distance is 10 m or more, the distance between the two is determined to be far, and if the distance is smaller than 10 m, the distance between the two is determined to be close. The
However, when the distance is determined only by the presence / absence of a wireless signal (reception availability), the distance threshold value may not be used.

In FIG. 4C, the result of determining whether the distance between the information processing apparatus 1 and the electronic device 2 is “near” or “far” and whether the electronic device 2 is in a stationary state (stationary or moving). Based on the result, whether or not to make a notification is set.
In the pattern 1 and the pattern 2 in FIG. 4C, when it is determined that the distance between the two is “near”, the notification is set not to be notified regardless of whether or not the electronic device 2 is stationary.
This is because, in the case of these patterns, it is considered that, in principle, the user has the information processing apparatus 1 and the electronic device 2 and is not left in a misplaced state.
However, both may be left in the same place, but are not considered here.

In the pattern 3 of FIG. 4C, when it is determined that the distance between the two is “far” and the electronic device 2 is determined to be stationary, the notification unit 30 of the electronic device 2 provides the notification number “H01”. It is shown that notification is performed by the notification method.
Here, as the notification method, for example, if the one shown in FIG. 4D is set in advance, the notification method of the notification number “H01” is “voice”.
Therefore, when the condition of pattern 3 is satisfied, the electronic device 2 is notified by voice.

In the case of pattern 3, since the distance between the information processing apparatus 1 and the electronic device 2 is more than a predetermined value and the electronic device 2 is in a stationary state, it is highly likely that the electronic device 2 has been misplaced. It is.
At this time, the user can easily notice that the electronic device 2 has been misplaced by notifying the electronic device 2 that has been misplaced by voice notification with a volume as high as possible.
In addition, since the voice is output from the electronic device that has been left behind, the user can quickly return to the electronic device 2 and retrieve the electronic device 2.

In the pattern 4 of FIG. 4C, when it is determined that the distance between the two is “far” and the electronic device 2 is not in a stationary state (moving state), the notification unit 30 of the electronic device 2 This indicates that notification is performed by the notification method of the notification number “H02”.
Here, as shown in FIG. 4D, since the notification method of the notification number “H02” is “vibration”, when the condition of the pattern 4 is satisfied, the electronic device 2 performs notification by vibration. Will be.
This is because, in the case of the pattern 4, for example, it is highly likely that the user has moved only with the electronic device 2 and has left the information processing apparatus 1 somewhere.
When the electronic device 2 is possessed, the user can notice that the information processing apparatus 1 is misplaced due to vibration of the electronic device main body.
However, in addition to vibration, a notification method such as voice or LED blinking may be performed in order to make sure that it is left behind.

FIG. 4D shows four notification methods, but the present invention is not limited to this. For example, “H05” may be set so that both voice and vibration are notified.
Alternatively, in the case of notification by voice, several voice output patterns may be set, or the volume of sound to be output may be varied.

If the distance is greater than the predetermined value, the process proceeds to step S4. If not, step S3 may be looped or may be returned to step S1.
In step S4, the stationary state detector 28 checks whether or not the electronic device 2 is in a stationary state.
If it is determined in step S5 that the vehicle is stationary, the process proceeds to step S6. Otherwise, the process proceeds to step S7.

In step S6, since the electronic device 2 is in a stationary state, it is determined that the electronic device 2 is in a misplaced state, and the notification switching unit 29 switches to a notification unit corresponding to the misplacement and notifies an alarm.
Here, the condition corresponding to the pattern 2 in FIG. 4A and the pattern 3 in FIG. 4C is satisfied, and according to the pattern 3 in FIG. An audio notification is performed by the audio output unit 33.

On the other hand, in step S7, since the electronic device 2 is not in a stationary state, it is determined that the electronic device 2 is not left misplaced, and the notification switching unit 29 switches to notifying means corresponding to other than misplacement and notifies an alarm. .
Here, the state corresponding to the pattern 3 in FIG. 4A and the pattern 4 in FIG. 4C is established, and according to the pattern 4 in FIG. Notification by vibration is performed by the vibration unit 32.
