Embodiment approach 1

[0035] figure 1 is a diagram showing an information display device according to Embodiment 1 of the present invention, figure 1 (a) is a block diagram showing an electrical configuration of an information display device, figure 1 (b) is a diagram showing the concept of the structure when the information display device is applied to glasses. The information display device includes an image input unit 1 , a line-of-sight detection unit 2 , an object recognition unit 3 , a timer 4 , a display position determination unit 5 , and an information display unit 6 .

[0036] The image input unit 1 is constituted by, for example, a video camera, and inputs an image corresponding to the user's field of view obtained by imaging the field of view of the user. The image input by the image input unit 1 is sent to the object recognition unit 3 .

[0037] The line-of-sight detection unit 2 detects the line-of-sight indicating which part of the user's observation field of view is present. Th...

Embodiment approach 2

[0056] Compared with the first embodiment, the information display device according to the second embodiment of the present invention simplifies the determination of the display position of the information presented to the user. The configuration of this information display device is the same as that of figure 1 The configuration of the information display device according to Embodiment 1 shown is the same.

[0057] The display position determination unit 5 of the information display device according to the second embodiment is different from the algorithm of the first embodiment in determining which part of the area in the field of view not observed by the user is used for information display. That is, in Embodiment 1, the display position determination unit 5 determines the largest area among the up, down, left, and right areas of the object recognized by the object recognition unit 3 as the display position of information. The display position is determined so that the cen...

Embodiment approach 3

[0069] In the information display device according to Embodiment 3 of the present invention, in the information display device according to Embodiment 1, the display position (area) of information presented to the user is further delimited so as not to obstruct the field of view as much as possible. The structure of this information display device is the same as that of the object recognition unit 3 and the operation of the display position determination unit 5 figure 1 The configuration of the information display device according to Embodiment 1 shown is the same.

[0070] Similar to Embodiment 1, the object recognition unit 3 recognizes and extracts an object including the gaze point sent from the line of sight detection unit 2 from the image sent from the image input unit 1, and recognizes and extracts an object located at a location determined by the display position. The object in the display area determined by the part 5. Information indicating the object area recognize...

Abstract

In order to provide an information display device capable of displaying information to be presented to a user without obstructing what the user is looking at, the present invention is provided with: an image input unit (1) that inputs an image corresponding to the field of view of the user; a line of sight detection unit (2) that detects a point of gaze representing the position of the line of sight in the field of view of the user; an object recognition unit (3) that extracts, from the image inputted from the image input unit (1), a region in an image of an object, which includes the point of gaze detected by the line of sight detection unit (2), as a first region; a display position determination unit (5) that determines, on the basis of information regarding the first region extracted by the object recognition unit (3), a position where the line of sight of the user does not strike in the field of view as a display position; and an information display unit (6) that displays information to be presented to the user at the display position determined by the display position determination unit (5).

Description

technical field [0001] The present invention relates to an information display device that superimposes and displays information provided to a user on an image or video in the real world. Background technique [0002] In recent years, AR (Augmented Reality: Augmented Reality) technology has started to be used. This AR technology adds and / or emphasizes information to the real world perceived by people through computers to expand the real world surrounding people. As a device using this AR technology, for example, a device including a camera and a small display device such as Google Glass launched by Google (registered trademark) is known. [0003] Devices using this AR technology use computers to generate information about objects in the field of view or objects that cannot be captured by the eyes, and prompt them in the field of view directly observed by people or in the real images captured by cameras, etc., thereby Support people's cognition. [0004] As such a technique...
