ABSTRACT
This chapter presents two IAS development case studies based on practical experience. The intent is not to give advice on the detailed design and implementation of these IASs, but to walk through the steps that were taken while illustrating the interaction-centered design perspective that was applied in both cases. The first case study describes the development of an intelligent adaptive interface (IAI) to control multiple UAVs. The design was implemented in support of the Canadian Armed Forces (CAF) UAV operator machine interface (OMI) requirements. The second case study describes the development of an intelligent tutoring system called QuestionIT. QuestionIT was developed to help CAF personnel acquire the skills necessary to effectively question witnesses following improvised explosive device (IED) attacks. These case studies are worked examples of the IAS development road map discussed in Chapter 7. They also describe a number of practical constraints that were encountered, which shaped and influenced how the two IASs were eventually developed. These constraints were by no means unusual; similar issues and constraints are likely to be encountered by any project team tasked to develop an IAS for a real-world application.
