Paper Abstract:	A study was performed to compare the relative performance, in terms of time to completion and accuracy, of desktop virtual reality, desktop stereo virtual reality, and a paper-based approach in presenting assembly instructions for 3D construction tasks. All presentations depicted a single step of the assembly process at a time. The results showed no significant differences in accuracy between any of the three approaches. A comparison of the two computer based presentations revealed that users rotated the model less frequently in the 3D stereo graphics than in the standard graphics, suggesting that more information was communicated by the stereo approach.
