User experience and User performance of feedback in a Pose Game.

Hoeijmakers, Niek J. (2011) User experience and User performance of feedback in a Pose Game.

Abstract:The goal of the research was to provide an enjoyable experience in posing. A pose game was developed that guided players to a desired pose. When the player reached the desired pose his image was placed in a �ctional scene as a reward. The game provided feedback in the form of a hint towards the desired pose, an indication of the distance between the desired pose and the player's current pose and, a mirror image of the player on screen. The input for the game was vision based. The Kinect provided the sensor data about the player's pose to the pose game. This thesis describes the study that aimed at evaluating the feedback of the pose game. Four feedback options were implemented in this study. With each option the hint towards the desired pose was varied. 1) The minimum feedback did not provide a hint. 2) The pose chain feedback showed in succession three silhouettes of poses describing the movement to the desired pose. 3) The inkspot transition had an unde�ned shape transforming into a silhouette as the player came closer to the pose. And 4) the focus image feedback showed an image of an object indicating the context and the focus of the pose. The study questioned which of these options had the best user performance, based on the constructs e�ectiveness and e�ciency, and which provided the best user experience, based on the constructs pleasure, engagement and satisfaction. The experiments were done in a laboratory setting and 28 participants, recruited from the University of Twente, provided their experiences with each of the four options through questionnaires and an interview. The order of the feedback was varied over four groups to balance the results. The results of the survey were analyzed using a repeated measures ANOVA. The feedback options, the participants and the respective measures were within subjects factors and the group of feedback order was the between subjects factor. For the analyses where task completion was a constraint a one-way ANOVA was used with the feedback options, the (un)completed tasks and the respective measure as the factors in the analyses. The results show that the pose chain feedback option gave the best user performance and provided the best user experience. The reason why most of the participants liked this option the best is that it was the most clear on what needed to be done. The inkspot transition and focus image were favored by some of the participants, because these were more challenging and required more creativity. The minimum feedback was the least favored and in general the participants were the most negative about it.
