The action action frame that family is made according to eyesight detection image, then judge whether action action frame is corresponding with corresponding eyesight detection image, in turn
According to judging result, examining report is generated, report is will test and is converted to corresponding report and display signal to display driving plate 3, is shown
Show that driving plate 3 shows signal according to report, generate corresponding report picture signal, send report picture signal to display screen 1 into
Row display, allows users to check examining report from display screen 1.
For example, eyesight detection image can be the E in E word visual chart, eyesight detection image can be different with display direction
E can individually show an E word, as target E word, so that user makes movement, can also show that one whole E word is used for
Show eyesight detection image Vission detector by being highlighted to the target E word for needing user to make a response, frame choosing or
The operation such as filling allows user to learn which the target E word reacted is, passes through display different directions, the E word of size
User is tested, user can according to pointed by target E word direction accordingly, made by gesture corresponding dynamic
Make；During camera 11 will collect test, whole gestures of user obtain motion images, sending action image to core
Control panel 2, core control panel 2 then using pre-generated action recognition model, analyze motion images, utilize action diagram
The timestamp of timestamp and display signal as in, action action frame and corresponding eyesight detection image are matched, and then judges
Whether the movement of user is identical as E word direction, generates examining report.
Wherein, after showing each eyesight detection image, it can wait and show next eyesight detection image after a certain period of time,
So that user has time enough to make corresponding movement, interior during this period, the movement that user makes will be controlled by core
Plate 2 is used.
Finally, it is to be noted that, herein, relational terms such as first and second and the like be used merely to by
One entity or operation are distinguished with another entity or operation, without necessarily requiring or implying these entities or operation
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant meaning
