The analysis of a user’s engagement to the task is an essential component for the assessment of the interaction for design efficiency. The investigation of task engagement requires considering users’ goal orientation since performance-oriented and learning-oriented individuals exhibit motivational differences. Learning-oriented individuals focus on progress and mastery, whereas performance-oriented individuals focus on their ability. We present an experimental investigation of users’ task engagement and its interaction with modalities to study the role of goal orientation in Human Computer Interaction tasks. Twenty-five participants participated in the study. They performed the same task with three alternative interaction modalities: a mouse, an eye tracker, and a Microsoft Kinect v2 sensor. The participants also filled in a goal orientation questionnaire and user engagement questionnaire. The findings revealed that different modalities resulted in different task completion times. The completion time was then used as a factor for the analysis of the efficiency of the interaction. Further analyses showed significant interactions among the participants’ goal orientation, their engagement scores, and the interaction modalities.
