Abstract

An information reading system includes a passive-type IC tag that identifies a device installed on side of an environment, a tag reader that reads identification information of the passive-type IC tag, a sensor unit that detects a touch operation performed with respect to the passive-type IC tag, and a reading control unit that, when the sensor unit detects a touch operation, activates the tag reader and controls timing of reading the passive-type IC tag.

Claims

1. An information reading system comprising:

a passive-type IC tag that identifies a device installed on side of an environment;

a tag reader that reads identification information of the passive-type IC tag;

a sensor unit that detects a touch operation performed with respect to the passive-type IC tag; and

a reading control unit that, when the sensor unit detects a touch operation, activates the tag reader and controls timing of reading the passive-type IC tag.

2. The information reading system according to claim 1, further comprising:

a first gadget that includes an antenna extended from the tag reader and a sensor used in detection performed by the sensor unit;

a second gadget that includes the sensor unit and the reading control unit;

a handheld device that makes use of identification information read by the tag reader, and executes a computer program for controlling execution of commands related to a task support provided to the device; and

a server device that provides data, which is to be used in the computer program, to the handheld device, wherein

the first gadget makes the second gadget return from a sleep state,

the second gadget makes the handheld device return from a sleep state, and

the handheld device makes the server device return from a sleep state.

3. The information reading system according to claim 1, further comprising a notification control unit that, when the reading control unit is driving the tag reader, issues a notification about driving of the tag reader.

4. The information reading system according to claim 1, wherein the passive-type IC tag is arranged in plurality in a matrix-like manner.

5. The information reading system according to claim 1, wherein the reading control unit performs control of a plurality of antennas extended from the tag reader or performs control of reading timing of a plurality of tag readers.

6. The information reading system according to claim 1, further comprising a passive-type IC tag that is attached to body of a worker who performs a task related to the device, wherein

the tag reader or the antenna extended from the tag reader is attached to the body of the worker, and

the reading control unit further controls the timing at which the tag reader reads information from the passive-type IC tag attached to the body of the worker.

7. The information reading system according to claim 1, further comprising a wearable gadget that includes an antenna extended from the tag reader or includes the tag reader, wherein

the wearable gadget is attachable to any one of a fingertip, ball of a finger, back of a finger, palm of a hand, back of a hand, periphery of a wrist, or a finger.

8. The information reading system according to claim 1, further comprising:

a relative position memory unit that is used to store, for each set of identification information of the passive-type IC tag, a relative position which represents a destination position of a device corresponding to concerned identification information and which is expressed by comparison with a marker placed in the environment;

a detecting unit that detects a marker from an image taken by a camera which is attached to head region of a worker who performs a task related to the device; and

a display control unit that refers to the relative position memory unit and, with reference to position of a marker displayed on a transmissive display which is attached to head region of the worker, displays, in a superimposed manner, information of a device corresponding to the identification information at a relative position from the reference and corresponding to the identification information read by the tag reader.

9. The information reading system according to claim 1, further comprising a detecting unit that detects, from an image taken by a camera which is attached to head region of a worker performing a task related to the device, a light source which flashes in tandem with the touch operation during detection of the touch operation, wherein

in an image displayed on a transmissive display that is attached to head region of the worker, information of a device corresponding to identification information read by the tag reader is displayed in a superimposed manner at position of the light source detected in the image by the detecting unit.

10. The information reading system according to claim 1, further comprising:

a narrowing unit that refers to identification information read by the tag reader and narrows down on a device installed around a device corresponding to the identification information; and

a detecting unit that performs image processing and detects a device narrowed down by the narrowing unit from an image taken by a camera which is attached to head region of a worker who performs a task related to the device, wherein

when the detecting unit detects the device from the image, in an image displayed on a transmissive display that is attached to head region of the worker, information of a device corresponding to identification information read by the tag reader is displayed in a superimposed manner at position of the device detected in the image by the detecting unit.

11. The information reading system according to claim 1, further comprising a recording unit that records an image taken by a camera which is attached to head region of a worker who performs a task related to the device, wherein

the recording unit records the image for a period of time during which sensor values obtained by a sensor included in a gadget that is attached to an arm, a wrist, or a finger of the worker satisfy a predetermined condition.

12. A reading control device comprising:

a sensor unit that detects a touch operation performed with respect to a passive-type IC tag which identifies a device installed on side of an environment; and

a reading control unit that, when the sensor unit detects a touch operation, activates a tag reader, which reads identification information of the passive-type IC tag, and controls timing of reading the passive-type IC tag.

13. A reading control method comprising:

detecting a touch operation performed with respect to a passive-type IC tag which identifies a device installed on side of an environment; and

controlling that, when a touch operation is detected, includes activating a tag reader, which reads identification information of the passive-type IC tag, and controlling timing of reading the passive-type IC tag.
