Download the Eye-Test App
Introduction
The Eye-Test App is made by Xiaoyu Wang, it first started as an small personal project aims to realize basic utility of conducting the standard logarithmic visual acuity test on a phone. After using App Inventor plateform to design the app, which simply applies basic logics of if-else statement in programming and inserting Tumble -E icons made by the author himself on Photoshop, Xiaoyu realized the app could become much more.
He did the following verification and adjustment, which pushed the app to the next level:
Conduct controled experiment, using random assignment to compare the result of phone testing with the actual visual acuity test in hospital. Ran the hospital three times, collect about 300 eyes’ result. He then use statistical method(chi-square, r-regression…) to verify the hypothesis that phone testing has good strong correlation with the standardized testing conducted in the hospital.
Adding history-keeping function
refined user-friendly interface
Psssss….The paper was accepted by The 20th Congress of Chinese Association for Pediatric Ophthalmology and Strabismus (CAPOS)
80% complete autonomous testing, with the power of deep learning(AI). The tester alone stand five meter away from the screen, and point his finger to indicate the direction of the Tumble-E sign just as usual, the computer vision(Squeeze-Net) module use the front camara to recognize the finger and thus achieves auto-testing function.
Bewear that the module’s prediction accuracy is still under 0.8, which means the user experience in this module will be under expectation!
HandBook
==The app is only for Android Users! IOS version will be here within months.==
After downloading the app, some users will experience alerts reported by the android system. The Eye-Test app only uses the camera for AI module recognition function and does not violate user’s privacy. Since the app could be used offline and there are no information being uploaded online, you can safely choose …
The App provides two type of test: the hands-on test and the automatic test. These tests are the standard logarithmic visual acuity tests. Test taker have to stand 5 meter away from the screen. Turn the screen on to the maximum light intensity and place the screen horizontal to the person’s eyes.
The hands-on test
Another personnel must assist to press the buttons to complete the test.
The automatic test
The test is automatic, with the aid of AI.
The history page
This page locally stores the test result along with date. Users can delete history, which is completed with pressing the target history record and press delete .
