What is it about?
CEMIT (Component Extraction & Motion Integration Test) is a novel, short, and easy visual test that uses a direction discrimination task. We hope it will help us to understand visual performance in the brain and tell us in particular how well observers can extract information about the moving patterns and how they are then perceived. This test allows us to measure individual visual performance at the neuronal level that no eye test or scanning technique could currently access. We hope to use it to help us understand visual deficits possibly associated with a number of clinical populations such as dyslexia, dementia, autism, and Alzheimer’s disease, as well as measure performance for screening purposes in occupations where visual information plays a very important role, e.g. drivers, pilots, or air traffic controllers.

Disclaimer: This CEMIT Lite app is part of a research study in visual perception and is intended for users who would like to participate in this study as experimental subjects. Please read the ethics form and instructions provided before running the test. The CEMIT test is made available to you for educational purpose only. It is not a clinically-approved diagnostic test and do not replace regular visits to your vision care specialist. The full version of CEMIT is also available on the App Store and is intended for vision & brain researchers who would like to carry out research studies in visual perception using the CEMIT test or users who would like to collect and access their own dataset.
This test was designed in laboratory by Dr. Linda Bowns (University of Cambridge, UK) and developed by Dr. William Beaudot (KyberVision, Sendai, Japan) to work on the iPhone, iPod touch and iPad devices.
