What information underwrites visual anticipation skill in dynamic sport situations? We examined this question on the premise that the optical information used for anticipation resides in the dynamic motion structures, or modes, that are inherent in the observed kinematic patterns. In Experiment 1, we analyzed whole-body movements involved in tennis shots to different directions and distances by...

With the rise in piano teaching recent years, many people have joined ranks of learners. However, high cost traditional manual instruction and exclusive one-on-one model made learning an extravagant endeavor. Most existing approaches, based on audio modality, aim to evaluate players’ skills. Unfortunately, these methods overlook information contained videos, resulting a one-sided simplistic eva...

We investigated the acquisition of skill in balancing a stick (52 cm, 34 g) on the fingertip in nine participants using three-dimensional motion analysis. After 3.5 h of practice over 6 wk, the participants could more consistently balance the stick for longer durations with greatly reduced magnitude and speed of stick and finger movements. Irrespective of level of skill, the balanced stick beha...
