Hand kinematics: Application in clinical practice

Ambulatory Assesment of Hand Kinematics

Analysis of hand kinematics is important in several application areas, such as rehabilitation, sports and ergonomics. In particular, ambulatory tracking of the whole hand configuration is valuable for kinematic assessment under daily life conditions. Current instrumented glove systems primary use resistive, magnetic or optical sensing methods [1]. A common drawback of these systems is that the ...

Hand kinematics of piano playing.

Dexterous use of the hand represents a sophisticated sensorimotor function. In behaviors such as playing the piano, it can involve strong temporal and spatial constraints. The purpose of this study was to determine fundamental patterns of covariation of motion across joints and digits of the human hand. Joint motion was recorded while 5 expert pianists played 30 excerpts from musical pieces, wh...

Analysis of Hand Synergies for Inverse Kinematics Hand Tracking

We present a method for real-time bare hand tracking that utilizes natural hand synergies to reduce the complexity and improve the plausibility of the hand posture estimation. The hand pose and posture are estimated by fitting a virtual hand model to the 3D point cloud obtained from a Kinect camera using an inverse kinematics approach. We use real human hand movements captured with a Vicon moti...
