TATRC Study Results

June 16th, 2010 by admin

The results are in from the Wichita State University Study funded by the US Army’s TATRC (Telemedicine and Advanced Technology Research Center).  We intuitively knew that THI was more efficient than the mouse/keyboard and a typical one-handed wand interface, but until now we had no scientific evidence to support our belief.  We were not surprised by the fact that THI was found to be superior to the mouse and wand for fundamental 3D tasks, but we were surprised by the extent of that efficiency gain–THI was found to be 4.5-4.7 times as fast as the mouse and 1.3-2.5 times as fast as the wand interface!

Also surprising was that there was no statistically significant differences in performance between stereoscopic and monoscopic displays.  In the scientific method, not finding a result does not mean that no result exists (we suspect we would find a difference with more data).  However, the large differences between interface type versus no measurable difference between display type implies that the type of interface is much more important than display type.
