A comparative study of monoscopic and stereoscopic display for a probe-positioning task.
We conducted a comparative study of task performance under both monoscopic and stereoscopic display conditions, in order to assess the role of stereoscopy in supporting an understanding of three-dimensional content, and ease of interaction with the data. As our application context is that of neurosurgical visualization, the experimental goal we chose was to define a straight, vessel-free path from the cortical surface to a targeted tumor. The scene consists of a volumetric representation of the brain vasculature and a simulated tumor, as well as a separately controlled pen-like virtual probe. Under both viewing conditions, participants were able to manipulate the volume and probe using a tangible user interface, thus obtaining hand-coupled motion cues. Results indicate that on average, participants were able to perform the task in the stereographic mode in only 75% of the time and with half the error as in the monoscopic condition.
