Abstract
A computer system for designing and performing interactive training sessions for training persons to perform procedures involving manual dexterity and/or eye-hand coordination, comprising a simulator for performing procedure simulations as well as modules for designing training scenes and procedure descriptions and for, during training, switching between an animation mode based on the procedure descriptions and an interactive mode where a trainee performs the procedures. The designing of training sessions include recording the execution of a procedure performed by an expert and converting this recording to a procedure description containing positional data for instruments as well as additional information including topological stamps indicating the occurrence of topological events in the scene description. During training sessions the system tracks the performance of the trainee relative to the execution represented in the procedure description in order to display guidance information and enable toggling between interactive mode and animation mode.
