Abstract

This output control system comprises: a specifying unit; and a first output control unit. The specifying unit specifies the position of a tablet by recognizing the code displayed on a tablet in a real space by using an imaging device. The first output control unit displays a shape representing an input area of the tablet of which the position is specified in a virtual space on the head-mounted display.

Claims (53)

1 . An output control system, comprising:

at least one memory storing instructions; and

at least one processor configured to execute the instructions to:

specify a position of a tablet by recognizing a code displayed on the tablet in a real space using an imaging device;

display a shape representing an input region of the tablet whose the position has been specified in a virtual space in a head mounted display; and

decrease a size of the code displayed on the tablet based on the code not being recognized for a predetermined period of time.

2 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

display writing on the tablet within the shape representing the input region of the tablet.

3 . The output control system according to claim 1 , wherein

the head mounted display includes the imaging device.

4 . The output control system according to claim 1 , wherein

the code is a two-dimensional code.

5 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

specify an inclination of the tablet; and

display the shape of the specified inclination.

6 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

specify a distance from the imaging device to the tablet; and

display the shape corresponding to the specified distance in the virtual space.

7 . The output control system according to claim 1 , wherein

the code is a plurality of codes displayed at different positions on the tablet.

8 . The output control system according to claim 1 , wherein

the tablet is a liquid crystal tablet,

wherein the at least one processor is further configured to execute the instructions to:

change at least one of the number of codes displayed on the liquid crystal tablet and a display position of the code is provided.

9 . The output control system according to claim 8 , wherein the at least one processor is further configured to execute the instructions to:

specify a distance from the imaging device to the tablet; and

change at least one of the number of codes displayed on the liquid crystal tablet and the size of the code displayed on the liquid crystal according to the distance.

10 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

specify a position of a pointing device capable of operating the tablet; and

display a mark indicating the specified pointing device or a contact point of the pointing device in the virtual space.

11 . The output control system according to claim 10 , wherein the at least one processor is further configured to execute the instructions to:

specify the position of the pointing device by infrared communication using the head mounted display.

12 . The output control system according to claim 11 , wherein the at least one processor is further configured to execute the instructions to:

specify the position of the pointing device by image recognition using the imaging device.

13 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

display the shape and the writing on the tablet at a position in the virtual space corresponding to a position of the tablet in the real space.

14 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

display the input region in a predetermined size in the virtual space based on an aspect ratio of the input region.

15 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

display a picture relevant to a use scene of the virtual space, wherein

a shape of the picture is the shape representing the input region of the tablet.

16 . The output control system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

acquire identification information of a head mounted display including an imaging device worn by a user;

compare predetermined identification information of the head mounted display associated with the recognized code stored in a code database with the acquired identification information of the head mounted display worn by the user, wherein the code database stores a code, identification information of a tablet, and identification information of a head mounted display in association with each other; and

display the shape representing the input region of the tablet whose position has been specified in the virtual space in the head mounted display of the user based on the predetermined identification information of the head mounted display associated with the recognized code matching the acquired identification information of the head mounted display worn by the user.

17 . An output control method, comprising:

specifying a position of a tablet by recognizing a code displayed on the tablet in a real space using an imaging device;

displaying a shape representing an input region of the tablet whose the position has been specified in a virtual space in a head mounted display; and

decreasing a size of the code displayed on the tablet based on the code not being recognized for a predetermined period of time.

18 . A non-transitory computer-readable recording medium recording a program causing a computer to execute processing for:

specifying a position of a tablet by recognizing a code displayed on the tablet in a real space using an imaging device;

displaying a shape representing an input region of the tablet whose the position has been specified in a virtual space in a head mounted display; and

decreasing a size of the code displayed on the tablet based on the code not being recognized for a predetermined period of time.
