Evaluation of the Effort to Mental Reconstruct the Objects from Technical Drawings
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2011, Vol 4, Issue 3
Abstract
In this paper is presented an experiment aimed to estimate the cognitive complexity of 2D technical drawings by measuring the reaction time and the accuracy of mentally reconstructed 3D images from 2D planar projections. From the performed experiment we can emphasize that the increased reaction time and reduced accuracy of 3D reconstructed brain images show the complexity the engineer is facing in the product development process. The precision and reaction time was not considerably improved by using 3D stereoscopic viewing. As a general conclusion, we can declare that improvement of actual 2D technical drawings by co-location of three dimensional models could be a viable alternative.
