Individualising Surgical Training in a Virtual Haptic Environment

Since safety and patient outcome are the most important criteria in surgery, training effectivity should be of primary importance when educating surgeons. Traditional surgical training focused on motor skills has today a number of limitations. Those can be overcome by using computer based training. Using a virtual environment and haptic force feedback, the training environment can be interactive looking like reality. This MSc thesis focuses on how to optimise the learning by individualising the training. To make the training as effective as possible, the teaching strategy must be best possible. Teaching strategy can be divided into a variable amount of demonstration, instruction and feedback and how this is presented for the user. Today there are no surgical training environment at the market providing individualised adjusted demonstration, instruction and feedback. Building on arguments from literature, discussions with experts and a product survey, the thesis present how to individualise surgical training in a virtual haptic environment. The thesis suggests and presents how teaching strategies can be designed to be flexible and support individuals. The demonstration, instruction and feedback are designed from knowledge about the trainee, previous result and actual performance. The thesis uses arguments that were found in literature and led to the design of teaching strategies. Further work should have been to include users as a next steep in the process.
