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...
