Practical Design of Information Interface

This paper deals with design examples for information interface that is defined as human user-information interactions through an information device. In the first part of the paper, we briefly review the model for the interface, and then give a design procedure based on a multiple regression (MR) model. In the second part of the paper, we explain two practical design examples. The first example deals with designing an interface for a computer generated motion picture by using an impressive quality measurement (semantic cost criterion). The second one deals with computer generated 3D city-map perception problem by using an object search time measurement (human cost criterion). Results for two design examples show the quality of interface is improved by adjusting system control parameters
