Adapting gameplay to eye movements – An exploration with Tetris

Gameplay experience is shaped by players’ expectations towards the game and how game features are presented to them. We created two modified versions of the classic TETRIS game: one that adapts game difficulty based on players’ performance and one that additionally adapts to players’ eye movements. An initial analysis of exploratory study results indicates that eye-movement-based adaptive difficulty in TETRIS might not affect player performance and that framing the use of adaptive difficulty might only have a limited influence on both players’ game experience and perceived competence.
