Wearable tracking device

1. A tracking display system comprising:

a processor that executes instructions that facilitate performance of operations, comprising:

displaying a view object in a virtual space;

detecting an image of a target in a real space, the target being for selecting the view object;

controlling at least a position of the view object, wherein

the view object is displayed such that the view object tracks a motion of the target, in a case where it is determined that the view object and the image of the target overlap with each other in a display device;

determining whether or not the target overlaps with the view object continuously for a predetermined time; and

displaying passage of the predetermined time with respect to the view object.

2. The tracking display system according to claim 1 , wherein

the target is at least any of fingers, palms, hands, and arms of a human body of a manipulator, and

the detecting is performed by at least any of a depth level sensor and an image sensor.

3. The tracking display system according to claim 1 , wherein, in a case where the target moves beyond a predetermined distance from a tracking start position of the view object, the operations further comprise ending the tracking display, and displaying the view object such that the view object returns to the tracking start position.

4. The tracking display system according to claim 1 , wherein the view object is at least any of an icon, a menu item, a text link, and a determination button.

5. A tracking display system comprising:

a view object displayed in a virtual space;

a target in a real space, for selecting the view object by a manipulator;

a processor that executes instructions to perform operations, comprising:

detecting a position of the target in the real space;

controlling at least a position of the view object in the virtual space, wherein

the view object is displayed such that the view object tracks a motion of the target, in a case where it is determined that the target exists in a predetermined space defined by a central projection from a point of view of the manipulator to the view object;

determining whether or not the target overlaps with the view object continuously for a predetermined time; and

displaying passage of the predetermined time with respect to the view object.

6. A wearable device comprising the tracking display system according to claim 1 .

7. A computer program product comprising a non-transitory computer-readable medium comprising a tracking display program that causes a processor to execute operations, comprising:

displaying a view object in a virtual space;

detecting an image of a target in a real space, the target being for selecting the view object;

controlling at least a position of the view object, wherein

the displaying of the view object is such that the view object tracks a motion of the target, in a case where it is determined that the view object and the image of the target overlap with each other;

determining whether or not the target overlaps with the view object continuously for a predetermined time; and

displaying passage of the predetermined time with respect to the view object.

8. A computer program product comprising a non-transitory computer-readable medium comprising tracking display program that causes a device coupled to a processor to execute operations, comprising:

displaying a view object in a virtual space;

selecting the view object by a manipulator using a target in a real space;

detecting a position in the real space;

controlling at least a position of the view object in the virtual space, wherein

the displaying the view object is performed such that the view object tracks a motion of the target, in a case where it is determined that the target exists in a predetermined space defined by a central projection from a point of view of the manipulator to the view object;

determining whether or not the target overlaps with the view object continuously for a predetermined time; and

displaying passage of the predetermined time with respect to the view object.

9. A tracking display program for a wearable device, comprising the tracking display program according to claim 7 .

10. A tracking display method, comprising:

displaying, by a device comprising a processor, a view object in a virtual space;

detecting, by the device, an image of a target in a real space, the target being for selecting the view object;

controlling, by the device, at least a position of the view object, wherein

the displaying of the view object is performed such that the view object tracks a motion of the target, in a case where it is determined that the view object and the image of the target overlap with each other;

determining, by the device whether or not the target overlaps with the view object continuously for a predetermined time; and

displaying, by the device, passage of the predetermined time with respect to the view object.

11. A tracking display method, comprising:

displaying, by a system comprising a processor, a view object in a virtual space;

selecting, by the system, the view object by a manipulator using a target in a real space;

detecting, by the system, a position in the real space;

controlling at least a position of the view object in the virtual space, wherein

the displaying of the view object is performed such that the view object tracks a motion of the target, in a case where it is determined that the target exists in a predetermined space defined by a central projection from a point of view of the manipulator to the view object;

determining, by the system whether or not the target overlaps with the view object continuously for a predetermined time; and

displaying, by the system, passage of the predetermined time with respect to the view object.

12. A manipulation method for a wearable device, comprising the tracking display method according to claim 10 .
