The goal of the proposed work is to analyze the characteristics and advantages of a telerobotic system based on video transmission and stereoscopic viewing. The proposed investigation follows a systematic approach based on the identification of main factors and a usability evaluation designed according them. Two different three-dimensional (3-D) visualization facilities are considered to evaluate its performance on systems with different characteristics, cost, and application context. The aim is to gain an insight into the problem and to understand on what system, and to what extent, is the stereo viewing beneficial. In the next section, we introduce visual sensors and stereo viewing. Then, the proposed investigation strategy is presented, followed by experimental design, test setup, and result analysis. Some final remarks conclude the article.
