摘要

In this work we describe our preliminary research on designing 3D Multimedia Visual Discrimination tests based on an innovative item type called the 2 Alternative Forced Choice (2AFC). We evaluate how human discrimination capability varies with the representation of 3D objects in terms of the structure (mesh), surface colors (texture), size, distance, and complexity of objects. Performance results are summarized. Some implications for educational testing are also discussed.
