Second Skin : motion capture with actuated feedback for motor learning
Second Skin aims to combine three-dimensional (3D) motion tracking with tactile feedback for the purpose of improving users' motor-learning ability. Such a system would track a user's body and limb movements as he or she performs an action, and then give the user automatic, real-time tactile …

Can changing running shoes immediately reduce the risk of tibial stress fractures?
… in this study. The test protocol utilized 3D motion capture, force plates, and EMG. The findings of the current study suggest that strike pattern and foot alignment rather than shoes are the determining factors in eliminating risk factors for TSF. Future works should involve fatigue studies …

The role of peripheral visual cues in planning and controlling movement :|ban investigation of which cues provided by different parts of the visual field influence the execution of movement and how they work to control upper and lower limb motion.
… several types of movement, namely overground locomotion, adaptive gait, postural stability and reaching and grasping. 3D motion capture techniques were used to collect limb and whole body kinematics during such movements. Visual peripheral cues were manipulated by visual field occlusion conditions …

The Impact of Race and Related Factors on Movement Mechanics
… After measuring self-selected walking speed, 3D motion capture and force plate data were recorded during 7 trials in the following conditions: regular walking (1.35m/s), fast walking (1.6m/s), running (3.2m/s), and drop vertical jump (31cm box height). Fundamental gait measures and running and …
