Quantitative assessment of 2D versus 3D visualisation modalities

Despite the growth of stereoscopic technology, there has been very little research done into the quantitative benefits of 3D over 2D visualisation systems. This study seeks to quantify and compare the human brain´s response to 2D versus 3D images using EEG technology, in particular focusing on the trend in changes between the p300 response resulting from 2D and 3D stimulus sequences using the oddball paradigm. It was found that the p300 response to the 3D stimuli degraded at a faster rate than the 2D stimuli as target spotting task difficulty was raised.
