When 200 trials are completed, there is an option to mail the data to our laboratory and to the user's email address. The data will be mailed in the form of a data sheet that contains information about the data collected (e.g. reaction times and correct responses for individual trials) and information about the variables selected for the test. The variables can be set before the test begins (e.g. size of noise, size of targets, ratio of black and white area, number of trials). After the data is mailed, the app provides a score of performance based on the speed and accuracy of the count. The score ranges from 0 to 100 (100 being best performance).
This visual test was inspired by published work from the laboratories of Drs. Jose Manuel Alonso and Qasim Zaidi (Komban et al., 2011, 2014; Wool et al, 2015). The app was written by Vandad Davoodnia as part of a collaboration between the laboratories of Dr. Reza Lashgari and Dr. Jose Manuel Alonso. The purpose of this app is to provide eye doctors with a tool for vision research. Collecting data with this app could also help to improve current visual tests and/or develop new tests that can be used to monitor the progression of a visual disease.
