An interactive computer animation method for learning instrument grasp

چکیده
In this paper we present a new 3D animation method for virtual learning of manual skills. The method is an extension of the recently developed keyboard based technique (KUI) for configuration and animation of hand gestures in 3D. The main contributions of the paper are: (1) the extension of the KUI method to include the basic manipulation tasks of grasping and releasing; (2) a new grasp classification which reduces the grasp types to six, with variations; (3) the development of a new HCI (Human Computer Interface) for efficient animation of grasp and release actions; and (4) the application of the method to learning the basics of instrument grasp in periodontal instrumentation. Because of the simplicity of the interface and low bandwidth for transmission, the method is particularly suitable for teaching, via internet, dexterous skills, which are one of the main obstacles to medical and other science-technology training at distance.

Learning Control Policies for Virtual Grasping Applications
Human grasping is one of the most challenging problems in computer animation. Physically based grasp synthesis involves coordination and contact, and depends on many variables such as the shape, size, texture, and physical properties of the target object. The traditional approaches have originated in the robotics community and employ a combination of motion planning (to move within reach of a t...
متن کاملGrasp synthesis from low-dimensional probabilistic grasp models
We propose a novel data-driven animation method for the synthesis of natural looking human grasping. Motion data captured from human grasp actions is used to train a probabilistic model of the human grasp space. This model greatly reduces the high number of degrees of freedom of the human hand to a few dimensions in a continuous grasp space. The low dimensionality of the grasp space in turn all...
