Visual ability tests are essential tools for Ophthalmologists and Optometrists and vision researchers to assess the status of basic visual abilities quantitatively for diagnose of the disease and monitoring its time course. Conventional tests require a help of professional assistance and often require time to measure (~several tens of minutes). From the view point of preventive health care, an easy test set which takes shorter measurement time and can be conducted by participants without professional assistance is expected. We, in this study, made a test battery consisting of with serious games for measuring visual abilities including fundamental visual function (perimetry, contrast sensitivity) and visual cognitive abilities (multiple-object tracking, visual crowding). The test is developed as a browser-based application using JavaScript and Web-GL libraries so that it runs on a wide range of tablet devices running iOS, Android OS and windows 10. Our priority for this test battery, which supposed to be used as a screening test, lies in the short measurement time and attractive graphical designs which aiming at increasing users’ motivation, rather than in the measurement accuracy. Therefore, we adopted simplified measurement methods and/or limited range of stimulus parameters. The expected time to conduct each game is less than 3 minutes. In addition, we adopted a simple way for the measurements of contrast sensitivity functions (CSFs) by developing methods for tablet PCs proposed by Mulligan (2016). We compared the results of CSF measurements by our methods and those by conventional methods (QUEST methods with CRT display) and confirmed that the CSFs from our test have a peak at similar (~2cpd) spatial frequencies as CSFs measured by conventional methods. Those features of the test battery are suitable for preventive health care and daily assessment of visual abilities.
