Until recently, courseware development was primarily a process that required sponsor endorsement of a design specification before implementation. (Lee, 2003) Instructional designers design and produce learning media with the assistance of skilled human resources, such as programmers, graphic designers, videographers, etc. (Stein, 2007) The major factor underlying the considerable initial costs ...

This paper discusses an iterative, engineering approach with an improved Conceptual Design Stage for the design of better hypertext. We emphasize the importance of getting design right “up front” so that many design blunders can be avoided. Task analysis and cognitive user modelling techniques are used to make design recommendations for rapid prototyping and testing of a prototype hypertext. We...

We have developed new methods for the automated assembly of prototype structures and we illustrate them with the construction of a simple one DOF 5mm surgical wrist employing polyester flexures instead of revolute joints. The first step in the structural assembly involves the construction of hollow stainless steel triangular beams that are used for the rigid elements of the structure. It includ...
