Objectives: Badminton performance analysis and profiling are essential steps in badminton coaching in order to identify the strengths and weaknesses of an athlete. Methods: In this paper, we investigated and identified the key potential and limitations of the Microsoft Kinect sensor for badminton performance analysis, particularly on novice badminton player. A survey was conducted during badminton event of SUKMA in order to determine which strokes are important to novice level player, where participants include coaches from different states of Malaysia. The essential strokes were then analyzed by Microsoft Kinect sensor. Findings: The survey results indicated that there are four main strokes to be mastered by novice level player, such as clear, net, lift and smash. Moreover, the key selected badminton strokes as identified by expert coaches such as forehand crosscourt lift, backhand touch net, backhand lift, forehand lift, forehand push net, backhand clear, backhand push net, forehand touch net and forehand clear can be measured and analyzed accurately and consistently with Microsoft Kinect sensor. However, the sensor measurements are limited for badminton strokes such as static smash, jump smash and overhead forehand clear. The major reason for such limitation is mainly due to occlusions and loss of acquisition data due to fast moving motion. Improvement: Therefore, the current performance analysis algorithm using skeleton information will be incorporated with color information in future to resolve the occlusion issue.
