Abstract

A system includes a first sensor configured to measure a location of a first device, a second sensor configured to measure an orientation of a second device, a display, and a processor. The processor is configured to control the first sensor to start a first measurement, calculate distances between the location of the first device and each of a plurality of installation locations associated with each of a plurality of objects, each of the plurality of objects being arranged virtually at each of a plurality of installation locations in a real space, control the second sensor to start a second measurement when a distribution of the distances indicates that any of the plurality of installation locations of the plurality of objects is included in a given range from the first device, and control the display to display an object according to results of the first measurement and the second measurement.

First claim

What is claimed is:

1. A system comprising:
a first sensor configured to measure a location of a first device;
a second sensor configured to measure an orientation of a second device;
a display; and
a processor configured to:
control the first sensor to start a first measurement of the location,
acquire first information indicating the location from the first sensor,
calculate, based on the first information, distances between the location of the first device and each of a plurality of installation locations associated with each of a plurality of objects, each of the plurality of objects being arranged virtually at each of a plurality of installation locations in a real space,
control the second sensor to start a second measurement of the orientation when the distances indicate that any of the plurality of installation locations of the plurality of objects is included in a given range from the first device,
acquire second information indicating the orientation from the second sensor,
control the display to display an object, from among the plurality of objects, according to the first information and the second information, and
control the second sensor not to execute the second measurement when the distances indicate that any of the plurality of installation locations of the plurality of objects is not included in the given range from the first device.

2. The system according to claim 1 , wherein the processor is configured not to control the second sensor to suspend the second measurement when the distances indicate that any one of the plurality of installation locations of the plurality of objects is included in the given range from the first device.

3. The system according to claim 1 , wherein
the system includes a head mounted display and a display control device,
the head mounted display is the second device, communicates with the display control device, and includes the second sensor and the display, and
the display control device is the first device, and includes the first sensor and the processor.

4. The system according to claim 3 , wherein the display is a non-transmissive head mounted display.

5. The system according to claim 4 , wherein the display displays a chart that indicates the location, the orientation, and relationship between the location of the first device and installation locations of at least one of object from among the plurality of objects.

6. The system according to claim 5 , wherein the chart is a radar chart.

7. The system according to claim 1 , wherein the first device is the second device.

8. The system according to claim 1 , wherein the plurality of objects corresponds to contents of augmented reality.

9. The system according to claim 8 , wherein the object is displayed on the display when the object corresponding to the location and the orientation exists.

10. A method executed by a processor, the method comprising:
acquiring location information indicating a location of a head mounted display;
calculating, based on the location information, distances between the location of the head mounted display and each of a plurality of installation locations associated with each of a plurality of objects, each of the plurality of objects being arranged virtually at each of a plurality of installation locations in a real space;
receiving sensor information including an orientation of the head mounted display from the head mounted display, the sensor information being measured by a sensor included in the head mounted display; and
when the distances indicate that any of the plurality of installation locations of the plurality of objects is not included in a given range from the head mounted display, transmitting, to the head mounted display, a signal for controlling the sensor not to execute a measurement of the sensor information or not to transmit the sensor information.

11. The method according to claim 10 , further comprising:
when the determination result indicates that there is no object, a signal for performing one or more out of control by which an interval of a detection operation of the sensor is lengthened and control by which an interval of transmission of the sensor information is lengthened, compared with a case in which the determination result indicates that there is an object, is transmitted to the head mounted display.

12. A method executed by a computer, the method comprising:
controlling a first sensor to start a first measurement of a location, the first sensor being configured to measure the location of a first device;
acquiring first information indicating the location from the first sensor;
calculating, based on the first information, distances between the location of the first device and each of a plurality of installation locations associated with each of a plurality of objects, each of the plurality of objects being arranged virtually at each of a plurality of installation locations in a real space;
controlling a second sensor to start a second measurement of an orientation when a the distances indicate that any of the plurality of installation locations of the plurality of objects is included in a given range from the device, the second sensor being configured to measure the orientation of a second device;
acquiring second information indicating the orientation from the second sensor;
controlling a display to display an object, from among the plurality of objects, according to the first information and the second information; and
controlling the second sensor not to execute the second measurement when the distances indicate that any of the plurality of installation locations of the plurality of objects is not included in the given range from the first device.

13. The method according to claim 12 , further comprising:
after the second sensor is controlled to start the second measurement, controlling the second sensor to suspend the second measurement when the distances indicate that any of the plurality of installation locations of the plurality of objects is not included in the given range from the first device.

14. The method according to claim 12 , further comprising:
controlling the display to display a chart that indicates the location, the orientation, and relationship between the location of the first device and installation locations of at least one of object from among the plurality of objects.

15. The method according to claim 14 , wherein the chart is a radar chart.

16. The method according to claim 12 , wherein the plurality of objects corresponds to contents of augmented reality.

17. The method according to claim 16 , wherein the object is displayed on the display when the object corresponding to the location and the orientation exists.
