Interactive sighting target display optimizing method

Abstract

The invention discloses an interactive sighting mark display optimizing method and relates to the field of sighting mark display. The method comprises the steps that a corresponding sighting mark is selected according to the sighting distance between a measured person and a sighting mark display screen and is displayed through the sighting mark display screen; whether the sighting mark displayed on the sighting mark display screen is changed or not is judged through input of the measured person until the sighting mark on the sighting mark display screen does not change. The method solves the problem that a measured person is likely to memorize directions of sighting marks in traditional paper sighting mark display, and also solves the problem that in the prior art, optimization selection on sighting marks according to the sighting distance between the measured person and the sighting mark display screen cannot be achieved. Besides, the sighting mark displayed on the sighting mark display screen is changed by judging whether the input of the measured person and the displayed sighting mark are same or not to replace the mode that in the prior art, sighting marks are changed through clock signal control and button pressing by relative working personnel, the sighting mark change can better conform to the practical situation of the measured person, and the recognition condition of the measured person to the current sighting mark is accurately judged.

Description

technical field [0001] The invention relates to an optotype display method, in particular to an interactive optotype display optimization method for selecting an eye chart based on the visual distance between a subject and an optotype display screen. Background technique [0002] With the continuous advancement of the information age, the implementation of vision testing methods is also constantly improving, gradually evolving from paper-based vision chart testing to today's intelligent vision testing combined with hardware and software. The main display methods of the visual mark are: [0003] 1) Display method of paper visual mark; [0004] 2) Based on the combination of the upper computer and the lower computer, the display method of displaying the visual target on a special display screen; [0005] 3) Replace the visual mark on the display screen through the clock signal in the control machine; [0006] 4) The staff can change the display of the optotype by pressing k...

Problems solved by technology

[0009] The object of the present invention is to provide an interactive optotype display optimization method, which can select a visual chart that is powerful for the subject, and can automatically replace the optotype according to the input of the subject, thereby solving the problem of traditional paper-based optotype. It shows that it is easy for the subject to remember the direction of each visual target, and it also solves the problem that the current technology cannot optimize the selection of the eye chart and visual target according to the visual distance between the test subject and the visual target display screen, and according to the input of the test subject. Adjust the display of the visual mark, etc.
