No / Advances in computer technology and developments such as the Internet provide a constant momentum to design new techniques and algorithms to support computer graphics. Modelling, animation and rendering remain principal topics in the filed of computer graphics and continue to attract researchers around the world." This volume contains the papers presented at Computer Graphics International 2002, in July, at the University of Bradford, UK. These papers represent original research in computer graphics from around the world

The purpose of this thesis was to contribute to our knowledge of what haptics can bring to the table as a human-computer interface rendering technique, which other rendering techniques cannot. An experiment was set up in which a multi-interfaced game was used to convey an information structure to interface users. Each of the game’s three user interfaces utilized one of three different rendering techniques: haptic rendering, graphic rendering, and graphic-haptic rendering. The capacity of each rendering technique to represent the information structure was assessed in terms of the effect of the corresponding interface on three aspects of the user interaction: user performance, user satisfaction and system usability. The result indicated that user performance benefitted from a graphic or graphic-haptic rendering over a haptic rendering. There were no differences between the rendering techniques with regards to the overall user satisfaction. However, there were notable differences on the user satisfaction metric subscale level. The haptic rendering required higher attentive effort than other renderings. Also, the graphic rendering better facilitated the perception of having clear goals and feedback. The results also suggested that the overall system usability benefitted from a graphic or graphic-haptic rendering over a haptic rendering.
