Ethyl PRO has the basic principle of evaluating the user and the changes that alcohol provides the human body.The AP acts as a collaborator in the awareness campaign against drinking, catching an assessment of the changes that alcohol promotes the reaction time of a healthy person.The test is simple, after a visual stimulus the user must touch the screen to calculate your reaction time, after three attempts the application brings an average time and compares it to the database of a healthy person, and stands if you passed or failed the puzzle.Its a great interaction for testing prior to practice some motor activity that involves responsibility, and is a fun competition between friends.Face this challenge and have fun.
