Spatial Orientation References in 3D Anatomy Apps
Abstract
In this research work the perception of 3D anatomy applications was evaluated in relation to a teaching strategy based on cognitive foundations of digital image manipulation. Two groups of students entering the medical career received training in the use of 3D anatomy software applications, only one of the groups received additional information on memory limitations in the retention of three-dimensional images and strategies for appropriate use of rotation controls that avoid cognitive overload. Perception was evaluated with a technology acceptance model (TAM) and a significant difference was found between both groups in favor of the trained group. We interpret We infer that the incorporation of 3D anatomy applications in traditional 2D screen devices will have greater acceptance (that is, probability of future use) when it is accompanied by a self-regulation strategy to avoid the disorientation effects produced by the characteristic uncontrolled rotations in self-taught use.
