The Effects of Stereoscopic Technologies on Subjects’ Ability to Perform a LEGO Block Construction Task
In recent years, one of the more popular ways of presenting information is as a three-dimensional graphical model on a computer. With 3-D graphics becoming more popular, they are starting to be used for instructional purposes. Instructions presented in 3-D should make performing a task easier than a task presented with two-dimensional instructions. BGSU researchers in computer science and psychology have conducted a number of studies that involved presenting instructions with three-dimensional graphics. The current study represents a convergence of the BGSU work involving the presentation of instructions for construction tasks and the use of stereo graphics. The task itself used a true three-dimensional artifact, a LEGO block, rather than the paper artifacts of the prior BGSU studies. The purpose of this study was to determine the effects of stereoscopic technologies on participants’ ability to perform a LEGO block construction task. This was a qualitative study that consisted of six participants who were all computer science graduate students. The task for this study was to construct a 111 piece LEGO tower for a pre-built castle. The tower construction task was divided into two parts with the participants building one part with the stereo glasses on and the other part with them off. The results of the study found that two of the six participants thought that the stereo glasses were a benefit in constructing the object. Most of the participants felt that the glasses did not help in constructing the object. The stereoscopic glasses for the most part do not appear to affect the results of the study. One reason the glasses did not appear to help was because the software provided enough features that the glasses were not necessary. There was also some indication that while performing the higher complexity steps the participants were slower when wearing the glasses.
