Increasing engagement in a MACT game through feedback and adaptability

Abstract

This thesis investigates improving attention control for Parkinson Disease patients in the context of Musical Attention Control Training (MACT). This is done by implementing a form of performance feedback within a pre-existing serious game. By applying concepts from providing feedback in serious games and introducing higher levels of musical diversity. More specifically applying Dynamic Difficulty Adjustment (DDA) using rhythmic difficulty levels. These levels are subdivided by difficulty based upon measures of syncopation. An experiment was conducted with 14 participants testing the proposed improvements. The data being gathered consisted of game-scores and game experience using a pre-and post game survey. These results were extended using qualitative interviews with participants and a music therapist. Different approaches for providing feedback and enhancing the gaming experience are discussed. Recommendations are given for future implementations and practical limitations are acknowledged. Results indicate added value for providing feedback, although more focus can be on the personalisation of the provided messages. Further suggestions are provided on how to improve engagement within a MACT-game.
