The largest eye-controlled videogames tournament featured 341 participants and was achieved by SpecialEffect at the Eurogamer Expo in London, UK, from 22-25 September 2011. Featured in Guinness World Records Gamers Edition 2012 The tournament used a proprietary camera system developed by SpecialEffect called 'gaze control' that tracks the line of sight of the participant's eyes using a camera. This data is then used to control a cursor on-screen that can be interpreted for videogame control.
