Toward Evaluating Material Design Interface Paradigms for Novice Users

摘要

Material design is the process by which artists specify the re-flectance properties of a surface, such as its diffuse color and spec-ular roughness We present a user study to evaluate the relative benefits of different material design interfaces, focusing on novice users since they stand to gain the most from intuitive interfaces Specifically, we investigate the editing of the parameters of analytic bidirectional distribution functions (BRDFs) using three interface paradigms: physical sliders by which users set the parameters of analytic BRDF models, such as diffuse albedo and specular rough-ness; perceptual sliders by which users set perceptually-inspired parameters, such as diffuse luminance and gloss contrast; and im-age navigation by which material variations are displayed in arrays of image thumbnails and users make edits by selecting them
