Abstract

A user can know the level of his/her own binocular vision. When an input instruction is input by the user via an input part, an information management part outputs a test request to a testing device, and a determination processing part obtains test results output from the testing device. The determination processing part determines a total level based on the test results and on information stored in a storage part. The determination processing part outputs the obtained total level to an output processing part. The output processing part generates a display screen in which the obtained total level and indices associated with the total level are written. The output processing part outputs the generated display screen to a display part. This causes the display part to display the display screen, and the user can know the concrete level of his/her own binocular vision.

First claim

The invention claimed is:

1. An information presenting device, comprising:
an obtaining part adapted to obtain results of tests related to a user's binocular vision;
a classifying part adapted to classify based on the obtained test results, the user's binocular vision into one of a plurality of classes; and
an output part adapted to output total level information suited to the user's binocular vision, based on the class into which the user's binocular vision is classified, to display part,
wherein:
(i) the test results obtained by the obtaining part comprise results of at least two test items selected from a stereo test, an accommodation time measuring test, a flicker test, a duration measuring test, a break strength measuring test, a left/right eye rotation angle measuring test, and a visual depth activity measuring test,
(ii) the classifying part calculates a temporary score point for each of the at least two test items, calculates a systematical score based on the calculated temporary score points, and classifies the user's binocular vision into one of the plurality of classes based on the calculated systematical score, and
(iii) the classifying part calculates the systematical score by multiplying the temporary score points by weighting coefficients that are associated with the test items, and adding up the weighted score points.

2. An information presenting device according to claim 1 , wherein the output part outputs, as the information suited to the user's binocular vision, information that indicates the class into which the user's binocular vision is classified.

3. An information presenting device according to claim 1 , further comprising:
a storage part adapted to store information related to a product in association with an appropriate one of the plurality of classes; and
a product determining part adapted to determine a product suitable for the user based on the class into which the user's binocular vision is classified and the information stored in the storage part,
wherein the output part outputs information related to the determined product as the information suited to the user's binocular vision.

4. An information presenting device according to claim 3 , wherein the information related to a product comprises at least one of a product name, a product type, and information introducing the product.

5. An information presenting device according to claim 3 , further comprising:
a Web server for providing a Web page;
an input part adapted to input a request to view detailed information of the determined product; and
a Web page obtaining part adapted to obtain when the viewing request is input by the input part, a Web page that contains a description about the determined product from the Web server,
wherein the output part outputs the obtained Web page to the display part.

6. An information presenting device according to claim 1 , further comprising:
a two dimensional image obtaining part adapted to obtain two-dimensional images; and
a three-dimensional image generating part adapted to generate based on the class into which the user's binocular vision is classified, from the obtained two-dimensional images, a three-dimensional image suitable for the class of binocular vision into which the user's binocular vision is classified,
wherein the output part outputs the generated three-dimensional image as the information suited to the user's binocular vision.

7. An information presenting device according to claim 6 , wherein the three-dimensional image generating part generates a three-dimensional image so that a parallactic angle associated with the class into which the user's binocular vision is classified by the classifying part is reached.

8. An information presenting system, comprising:
a terminal device; and
a server connected to the terminal device,
the server comprising:
an obtaining part adapted to obtain results of tests related to a user's binocular vision;
a classifying part adapted to classify, based on the obtained test results, the user's binocular vision into one of a plurality of classes; and
an output part adapted to output total level information suited to the user's binocular vision, based on the class into which the user's binocular vision is classified, to the terminal device,

wherein:
(i) the test results obtained by the obtaining part comprise results of at least two test items selected from a stereo test, an accommodation time measuring test, a flicker test, a duration measuring test, a break strength measuring test, a left/right eye rotation angle measuring test, and a visual depth activity measuring test,
(ii) the classifying part calculates a temporary score point for each of the at least two test items, calculates a systematical score based on the calculated temporary score points, and classifies the user's binocular vision into one of the plurality of classes based on the calculated systematical score, and
(iii) the classifying part calculates the systematical score by multiplying the temporary score points by weighting coefficients that are associated with the test items, and adding up the weighted score points.

9. An information presenting system according to claim 8 , further comprising a Web server for providing a Web page,
wherein the server further comprises:
a storage part adapted to store information related to a product in association with an appropriate one of the plurality of classes;
a product determining part adapted to determine a product suitable for the user based on a class into which the user's binocular vision is classified and the information stored in the storage part; and
a Web page obtaining part adapted to obtain a Web page that contains a description about the determined product from the Web server,

wherein the output part outputs the obtained Web page to the terminal device total level information suited to the user's binocular vision,
wherein:
(i) the test results obtained by the obtaining part comprise results of at least two test items selected from a stereo test, an accommodation time measuring test, a flicker test, a duration measuring test, a break strength measuring test, a left/right eye rotation angle measuring test, and a visual depth activity measuring test,
(ii) the classifying part calculates a temporary score point for each of the at least two test items, calculates a systematical score based on the calculated temporary score points, and classifies the user's binocular vision into one of the plurality of classes based on the calculated systematical score, and
(iii) the classifying part calculates the systematical score by multiplying the temporary score points by weighting coefficients that are associated with the test items, and adding up the weighted score points.

10. A server, which is a constituent of the information presenting system according to claim 8 .
