Video Analysis for Includification Requirements

In extensive trials we asked participants with disabilities to play a set of computer games, demanding a variety of cognitive and physical skills. In particular we presented a Tetris variant we developed ourselves, which follows various includification guidelines. Participants were recorded on video in order to identify strengths and weaknesses in coping with the presented game challenges. In the videos we recorded the game screen, a frontal video of the participants showing emotional responses, and eye gaze. Post processing tasks are used to analyze and retrieve data from the videos. This helps to build up a video database for later analysis and answer questions raised after the recordings were taken.
