This paper presents a case study of the replacement of a textbook with free to use materials in a class on Human Factors and Ergonomics. Data on exam grades, course grades, and student opinions over a total of five semesters are reported, before and after the implementation. The results show that class performance remained similar before and…

User input is an important component to help guide designers in producing a more usable product. Evaluation of prototypes is one method of obtaining this input, but methods for evaluating assistive technology prototypes during design have not been adequately described or evaluated. This project aimed to compare different methods of evaluating…

Many different sources of input are available to assistive technology innovators during the course of designing products. However, there is little information on which ones may be most effective or how they may be efficiently utilized within the design process. The aim of this project was to compare how three types of input--from simulation tools,…
