Competitive Street Fighter is an amazing thing to behold, more so when you can see how the players watch the action on screen as they dish out damage.
In this video, we get to see where one of Japan's top Street Fighter players, Sako, is looking as he plays a match as Elena. A SteelSeries Sentry Gaming Eye Tracker was used to capture where Sako was focusing his attention and display it on the 4Gamer.net YouTube video as a grey circle.
It's an interesting way to analyze play. Just watching it once, I couldn't help but notice that most of Sako's attention was paid to the space right in front of Ken. He also seems to occasionally predict the next move, or track where he knows he or is enemy will land.
