Abstract

A display system includes a portable display device; a distance detection section that detects a distance between a work object and the portable display device; and a display control section that displays object-related information, which indicates content relevant to the work object, on the portable display device. The display control section changes an object-related information display mode in the portable display device according to a result which is acquired in such a way that the distance detection section detects the distance.

Claims

1. A display system comprising:

a portable display device;

a distance detection section that detects a distance between the portable display device and a work object which communicates with the portable display device; and

a display control section that displays work object-related information, which indicates content relevant to the work object, on the portable display device,

wherein the display control section changes a work object-related information display mode in the portable display device according to a result which is acquired in such a way that the distance detection section detects the distance,

wherein, when the distance which is detected by the distance detection section changes in order of a first distance, a second distance which is shorter than the first distance, and a third distance which is longer than the second distance, the display control section causes the display mode in which the work object-related information is displayed according to the detection of the first distance and the display mode in which the work object-related information is displayed according to the detection of the third distance to be different from each other.

2. The display system according to claim 1,

wherein the display control section changes a shape of a display area, in which the work object-related information is displayed, according to the distance which is detected by the distance detection section.

3. The display system according to claim 1,

wherein the display control section changes the display mode according to a size relation between the distance, which is detected by the distance detection section, and a threshold.

4. The display system according to claim 1,

wherein, the display control section causes the display mode in which the work object-related information is displayed according to the detection of the first distance, the display mode in which the work object-related information is displayed according to the detection of the first distance, the display mode in which the work object-related information is displayed according to the detection of the second distance, and the display mode in which the work object-related information is displayed according to the detection of the third distance to be different from each other.

5. The display system according to claim 1,

wherein the display control section is configured to handle a plurality of work objects, displays the work object-related information for a work object which is selected from among the plurality of work objects, and does not display the work object-related information for the work objects which are not selected.

6. A display system comprising:

a portable display device;

a distance detection section that detects a distance between the portable display device and a work object which communicates with the portable display device; and

a display control section that displays work object-related information, which indicates content relevant to the work object, on the portable display device,

wherein the display control section changes a work object-related information display mode in the portable display device according to a result which is acquired in such a way that the distance detection section detects the distance,

wherein the display control section changes the work object-related information display mode in the portable display device according to a history of a change in the distance detected.

7. A portable display device comprising:

a display for displaying information related to an object whose image is viewable on the display,

wherein the portable display device communicates with the object for displaying the information on the display, and

the information is displayed upon occurrence of an event in the object,

wherein, if a distance between the portable display device and the object is less than a threshold distance, the display displays an icon which, when selected, is configured to execute a display mode of the information.

8. The portable display device according to claim 7,

wherein a display mode of the information is changed based on a distance between the portable display device and the object.

9. The portable display device according to claim 7,

wherein the icon is configured to stop being displayed after it is selected.

10. The portable display device according to claim 7,

wherein the icon, when selected, is configured to fix the display mode of the information, regardless of the distance between the portable display device and the object.
