Abstract
The invention discloses an intelligent and multifunctional Chinese character visual chart and relates to the field of medicine. The intelligent and multifunctional Chinese character visual chart is mainly characterized by comprising a Chinese character 'tian' and fourteen other Chinese characters transformed from the Chinese character 'tian'. The intelligent and multifunctional Chinese character visual chart is mainly used for vision tests, a tester can use a remote controller to select to-be-displayed Chinese characters and regulate the sizes of the Chinese characters, a to-be-tested person is requested to recognize the Chinese characters, and the tester can judge the vision condition of the to-be-tested person according to correctness of answers of the to-be-tested person; the to-be-tested person can also hold the remote controller and complete a self-testing by recognizing different-sized Chinese characters randomly emerging on a screen. The intelligent and multifunctional Chinese character visual chart also has an additional function, the color vision of the to-be-tested person can be tested through the change of screen background colors and Chinese character colors, and patients with color blindness can be identified.
Description
Technical field
The present invention relates to medical domain.The present invention is specifically mainly used in the detection of vision.
Background technology
At present, extensive use E word visual acuity chart and C word visual acuity chart carry out eyesight measurement on the market, but function singleness, the opening direction of E and C word only has four kinds of directions up and down, add the probability that people answer questions by mistake, this brings inconvenience in fields such as the qualified detections of pilot, we have invented " intelligent multi-function Chinese character visual acuity chart " for this reason.The present invention's application Chinese character " field " and conversion 14 kinds of Chinese characters out thereof are expanded E word visual acuity chart, enrich the function of visual acuity chart, add the number of font in visual acuity chart, and this visual acuity chart is integrated in smart machine fiery in the market, has more enriched the function of visual acuity chart.
Summary of the invention
The object of the invention is the function in order to enrich existing visual acuity chart, making up the deficiency of existing visual acuity chart.
Composition of the present invention: display, remote controller are as Fig. 1 and Fig. 2.
All Chinese characters used in this visual acuity chart are as Fig. 3.
The application function of this visual acuity chart divides three parts.Part I, be traditional survey vision method, measured stands in five meters of distant places, and a hands covers an eye, and another eye fixation screen, by tester's auxiliary detection; Tester's hand-held remote controller, random choose chinese disply on screen, and adjusts font size, and saying Chinese character as shown on screen by measured is what, and test the vision of measured with this, workflow is as Fig. 4.Part II, for novel method of testing, measured's hands covers an eye, another hands hand-held remote controller, stand in the place far away apart from screen five meters, automatically generated the Chinese character of different size by computer, measured finds out the Chinese character on screen from remote controller, the vision of computer automatic decision measured, workflow is as Fig. 5.Part III, the font of display can have different colors, and the color of display has: red, green, blue, green grass or young crops, orange, Huang, purple.This function is mainly used in the colour vision checking testee, and when using this function, display background color and Chinese character color are all in continuous change.As, anerythrochloropsia disease patient cannot differentiate redness and green, so when display background color is red (or green), when Chinese character is green (or red), correctly cannot differentiate the Chinese character in screen.
When visual acuity chart of the present invention runs, screen display as shown in Figure 6.User selects the Chinese character that will show on a remote control, then can demonstrate corresponding Chinese character in the middle of screen.When user presses the "+" button of remote controller the top a line, font can become large; When user presses the "-" button of remote controller the top a line, font can diminish.All fonts all change size, with identical 0.1-2.0 inspection requirements by visual acuity chart unlike signs specification.
Claims (3)
1. intelligent multi-function Chinese character visual acuity chart, comprises Chinese character visual acuity chart, display and remote controller composition, it is characterized in that used visual acuity chart is made up of Chinese character " field " and 14 kinds of Chinese characters by its conversion.
