Abstract

A mobile electronic apparatus includes a memory that stores a search range of an object and a processor that executes a process. The process includes acquiring a moving speed of the mobile electronic apparatus, determining the search range of the object on a basis of the moving speed, detecting the object existing within the search range, detecting whether a display unit of the mobile electronic apparatus is in an active state, and notifying that the object is detected when the display unit is detected to be in the active state and the object existing within the search range is detected.

Claims

1. A mobile electronic apparatus comprising:

a memory that stores a search range of an object; and

a processor that executes a process including

acquiring a moving speed of the mobile electronic apparatus;

determining the search range of the object on a basis of the moving speed;

detecting the object existing within the search range;

detecting whether a display unit of the mobile electronic apparatus is in an active state; and

notifying that the object is detected when the display unit is detected to be in the active state and the object existing within the search range is detected.

2. The mobile electronic apparatus according to claim 1, wherein

the acquiring a moving speed includes:

acquiring an activity intensity of a user of the mobile electronic apparatus on a basis of a value which is metered by an acceleration meter in the mobile electronic apparatus, and

converting the activity intensity into the moving speed on a basis of predetermined relation between the activity intensity and the moving speed.

3. The mobile electronic apparatus according to claim 1, wherein

the determining the search range determines a distance corresponding to the moving speed acquired in the acquiring on a basis of predetermined relation between the moving speed and the distance for specifying the search range, and

the detecting the object existing within the search range compares a value which is metered by a distance meter in the mobile electronic apparatus, to the distance determined in the determining the search range.

4. The mobile electronic apparatus according to claim 1, the process further comprising:

determining whether a user of the mobile electronic apparatus is walking,

wherein the notifying notifies that the object is detected when the user is determined to be walking

5. The mobile electronic apparatus according to claim 1, the process further comprising:

determining whether a user of the mobile electronic apparatus is walking,

wherein the acquiring a moving speed acquires the moving speed when the user is determined to be walking

6. The mobile electronic apparatus according to claim 1, wherein

the acquiring a moving speed acquires the moving speed when the display unit is detected to be in the active state.

7. The mobile electronic apparatus according to claim 1, wherein

the determining the search range determines the search range when the display unit is detected to be in the active state.

8. A danger notifying method which is used in a mobile electronic apparatus, the method comprising:

acquiring a moving speed of the mobile electric apparatus;

determining a search range of an object on a basis of the moving speed;

detecting the object existing within the search range;

detecting, using a processor, that a display unit of the mobile electronic apparatus is in an active state; and

notifying that the object is detected when the display unit is detected to be in the active state and the object existing within the search range is detected.

9. A computer readable recording medium for storing a program causing a mobile electronic apparatus to execute a process, the process comprising:

acquiring a moving speed of the mobile electric apparatus;

determining a search range of an object on a basis of the moving speed;

detecting the object existing within the search range;

detecting, using a processor, that a display unit of the mobile electronic apparatus is in an active state; and

notifying that the object is detected when the display unit is detected to be in the active state and the object existing within the search range is detected.
