Advances in information technology have provided educators with the tools needed to present abstract concepts in a clear and concise manner. These tools can be particularly effective in the field of computer science where the dynamic processes of algorithms must be conveyed to students at all course levels. This paper presents a case study in the development of web-based tools for students learning about sensor systems. More specifically! an educational web site to supplement a textbook on sensor fusion is presented. The site uses Java visualization software and analogy based multimedia to reinforce concepts related to the text. The site places particular emphasis on image registration, which is the process offending the optimal mapping between two or more overlapping images. Image registration source code included with the text Multi-Sensor Fusion was rewritten in Java 2, numerous improvements were made, and a new registration technique known as TRUST was added.
