Purpose: This stuy control the visual conditions (actual image and point-light image) to understand the location anticipation accuracy for badminton serve. Method: Purposive Sampling. At first, 12 elite badminton players were recruited as the participants (Age: 24.4±5.3 years old; Experience: 13.3±4.0 years) watching the film of how one badminton player served , which was processed to actual images and point-light images afterwards by using Motion Capture System (Qualisys Track Manager) and DV camcorder as apparatuses. These players were required to observe and to predict the location. The anticipation accuracy will become the dependent variable of this research after been calculated. By making use of one-sample t test, we will examine the effect on participants' anticipation of actual images and point-light images, and paired-sample t test to examine for participant anticipation accuracy of actual images and point-light images. Results: 1. No matter in actual image (54.7%±13.7%) or point-light image (50.5%±15.3%), there are significant anticipation effect on participants anticipation accuracy. 2. There is no significant difference between actual image and point-light image for anticipation accuracy of the serve location. Conclusions: 1. The elite badminton players are able to predict the location by using the information that the actual image and point-light image provided. 2. The results of the study provide evidence to support the invariant property of information that the point-light display of the sever movement offers sufficient information for identifying the location.
