If you've ever wondered how quickly your brain can process visual information, then Eye Speed is just the app for you! Eye Speed provides users with a test to measure their visual reaction times. The purpose of this app is to provide eye doctors with a tool for vision research and inspire new visual tests to monitor the progression of visual disorders. So not only will you be able to measure your reaction time, but also contribute to world-class vision research! The Pre-Trial stage is where you can configure the trial's settings to your liking. You may adjust the Noise Square Width, Target Width, and Black area to the total area ratio in order to modify the difficulty. Please note that all three settings have bounds, if you set a value outside the bounds, then you will receive a warning, and the settings will reset to the default values. The trial stage is the bulk of the application. When ready, you may start the test by pressing the tab 'Start Trial' at the bottom. After the tab is pressed, a visual stimulus will appear on the screen. The visual stimulus is composed of black and white squares embedded in a noisy background. You must count the number of Target squares as fast as you can and press the tab with the correct number: |1| |2| |3|. Once a tab is pressed, another stimulus appears. This sequence is repeated until the number of trails set is met. A minimum number of trials (5) is required to obtain reliable data and contribute to the research. However, you may finish the test at any time by pressing the tab 'End Trial'. The post-trial is the final stage of the application. Here, you can see how well you did during the test. If you completed 5 or more trials, then there is an option to mail the data to our laboratory and to the user's email address. The data is mailed in the form of a data sheet (.csv file) that contains information about the data collected (e.g., reaction times and correct responses for the individual trials) and information about the variables selected for the test (the configuration done in the Pre-Trial). Please check our privacy policy for any concerns on data collection and processing. After the data is mailed, the app provides a performance score based on the speed and accuracy of the count. The score ranges from 0 to 100 (100 being the best performance). Thank you for downloading our app and contributing to our research!

The application records slow-motion video of eye movements while a user follows a visual target displayed on the iPhone screen. After recording, users can select a corneal reflection of the screen and a facial reference point to visualize eye movement changes as graphs. The recorded data can be used to review horizontal and vertical eye position and velocity changes for research and educational purposes.
