Abstract

An information processing device includes a storage unit configured to store a predetermined motion of a user who uses an operating device and an attribute of the predetermined motion per role of the user in association with each other; an image capturing unit configured to capture an image of a predetermined area including a projection area on which a projecting device projects an image; an identification unit configured to identify the attribute associated with the predetermined motion corresponding to a motion of light emitted to the predetermined area from the operating device based on the motion of light and an operation signal, referring to the storage unit; a synthetic image generation unit configured to generate a synthetic image by reflecting the attribute of the predetermined motion in the image projected; and a history record unit configured to generate history data including the synthetic image, the role, the attribute.

Claims

1. An information processing device for detecting operation of a plurality of operating devices, each operating device including a light emitting unit, the information processing device comprising:

a role information storage unit configured to store therein role information in which each of the operating devices is associated with any one of roles assigned to a user who operates the each of the operating devices;

an operation information storage unit configured to store therein operation information in which motions of light to be emitted from the light emitting unit of the operating device are associated with instructions to the operating device indicated by the motions, respectively;

an image capturing unit configured to capture the motion of the light emitted by the operating device to a projection area on which a projecting device projects an image;

a role determining unit configured to determine, based on the role information, a role of a user assigned to the operating device having emitted the light captured by the image capturing unit;

an instruction determining unit configured to determine, based on the operation information, an instruction indicated by the motion of the light captured by the image capturing unit; and

a history data generating unit configured to generate history data by recording information on the instruction determined by the instruction determining unit,

wherein, when the instruction determining unit determines the instruction as an instruction to change display on a screen, the history data generating unit generates history data in minutes format in which the instruction is recorded and an image being displayed on the screen is marked based on the instruction, and a description of the instruction is associated with an image to be displayed on the screen after changing display in the history data.

2. The information processing device according to claim 1, wherein the history data includes role information of each user who operates each of the operating devices, and a start time and an end time.

3. The information processing device according to claim 1, further comprising a synthetic image generation unit configured to generate a synthetic image obtained by synthesizing an indication of the instruction determined by the instruction determining unit and the projected image when the role determining unit determines the role as a predetermined role, and record the synthetic image into the history data.

4. The information processing device according to claim 1, wherein the marked image and the description of the instruction are numbered in order.
