Title:
CONVENIENT RAPID CONTRAST SENSITIVITY TEST SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/202255
Kind Code:
A1
Abstract:
A convenient rapid contrast sensitivity test system, comprising a test end and a computation end. The test end is connected to the computation end. The test end is used for generating and presenting an optotype to a subject, collecting a "visible-or-not" feedback and physical information of the subject to adjust an optotype generation parameter, and finally obtaining a next optotype parameter by means of a feedback result. The computation end provides requirements such as a hashrate, storage, an algorithm, and parallel computing control required for optotype recommendation. The interaction mode is improved, the test accuracy is guaranteed, a higher test speed is achieved by redesigning the interaction mode, and the test can be completed within one or two minutes. The intervention of medical personnel is not needed, the subject can independently complete interaction, and the result is objective. The system may also be used in cooperation with a mobile device such as a tablet for portable testing, thereby facilitating out-of-hospital test for a doctor.
