The Relationship Between Virtual Reality Sickness and Change of AC/A ratio

My science project is to create a virtual reality app and do an experiment to see how it changed people’s AC/A ratio as well as how badly they experienced virtual reality sickness. Specifically, I used a gaming app called Unity that makes me create my own video games. I created a car racing game. I also measured people’s AC/A ratio before and after playing the virtual reality. Not only would I be testing people their AC/A ratio, but how badly they experience virtual reality sickness. I chose the four most common symptoms, including nausea, dizziness, headache, and tiredness. I asked these questions before the person plays VR after the person plays VR and every 15 minutes from that moment until an hour passed. I will also perform the same procedure for testing people’s AC/A ratio. I performed this experiment with 10 different people. The age of those people ranged from 9 - 40. I didn’t want to test someone over 40 because some people that are beyond that age might experience eye conditions such as presbyopia, a condition where your eyes have trouble converging. After I conducted this experiment on enough people, I tallied all the results and put on a graph to see how badly their AC/A ratio changes and how badly they have experienced virtual reality sickness.
