| Popis: | During endoscopic surgery, communication between the operator and the assistant is an important problem to solve to prevent medical errors and to make the operation more efficient and precise. We have been developing an AR-based application for communication support in endoscopic surgery. This application has a function to enable line and shape drawings on the endoscopic images under the AR environment. The application enables the drawing of these images by head motions. To verify the effectiveness of this application, it was necessary to evaluate how much performance the drawing function by the head motion can provide the operator. In this paper, we investigated whether the drawing function by head motion offers effective performance for communication during endoscopic surgery by comparing the operation accuracy of the linear and circular drawings by direct hand motion and indirect mouse motion and modeled using the steering law. Results of the experiment demonstrated that the relationship between indices of difficulty and movement time was well modeled using steering law with more than 97% of coefficient of determination for all three input methods. In conclusion, the precision of drawing by head motion cannot exceed that of by hand and mouse when it is necessary to draw a circular object. It was suggested that the effectiveness of head motion drawing existed when the drawing lines were not precise, possibly for communication between typical practitioners and assistants, drawing straight lines or relatively rough shapes. |
