Inclusive design is a concept intended to promote the development of products and environments equally usable by all users, irrespective of their age or ability. This research focuses on developing a method to derive heuristics for inclusive design. The research applies the actionfunction diagram to model the interaction between a user and a product, design difference classification to compare a typical product with its inclusive counterpart, graph theory to mathematically represent the comparison relations, and graph data mining to extract the design heuristics. The goal of this research is to formalize and automate the inclusive-design heuristics generation process. The rule generation allows statistical mining of the design guidelines from existing inclusive products. Formalization results show that, the rate of rule generation decreases as more products are added to the dataset. The automated method is particularly helpful in the developmental stages of graph mining applications for product design. The graph mining technique has capability for graph grammar induction, which is extended here to automate the generation of engineering grammars. In general, graph mining can be applied to extract design heuristics from any discrete and relational design data that can be represented as graphs. Concept generation studies are conducted to validate the heuristics derived in this research for inclusive product design. In addition, an inclusivity rating is created and verified to evaluate the inclusiveness of the conceptual ideas. Finally, appreciation and awareness about inclusive design is important in an engineering design course, hence, a module is compiled to teach inclusive design methods in a capstone design course. The results of the exploratory study and validation show that there is problem dependency in the application of the representation scheme. It cannot be stated with certainty at this point if the representation scheme is helpful for designing consumer products, where only the activities related to the upper body are involved. However, self-reported feedback indicates that the teaching module is effective in increasing the awareness and confidence about inclusive design.

This thesis explores how Natural User Interface (NUI) interaction and Multiple Display Technology (MDT) can be applied to an existing Freight Management System (FMS), to improve the command and control interface of the dispatch operators. Situational Awareness (SA) and Task Efficiency (TE) are identified as being the main requirements for dispatchers. Based on studies that have been performed on SA and TE in other time critical occupations such as Emergency Medical Dispatch (EMD) and Air Traffic Control (ATC), a substitute dispatch display system was designed with focus on courier driver and freight management systems and monitoring. This system aims to alleviate cognitive overheads without disrupting the flow of the existing CFMS by providing extended screen area matched with a natural input mechanism for command and control functionality. This Master’s thesis investigates which of commercial state-of-the-art interface tools is best to use in a wide Field-of-View (FOV) multiple screen display and to dicern if there is any practical impact that a proposed NUI system will have to courier dispatching. To assess the efficacy of such a hypothetical system the author has developed an experimental prototype that combines a set of three monitors in a Multi-Monitor System to create the overall display system, accompanied with two traditional and two advanced NUI direct and indirect interaction techniques (mouse, trackpad, touch screen and gesture controller). Experiments using the prototype were conducted to determine the optimum configuration for control/display interface based upon task effectiveness, bandwidth and overall user desirability of these methods in supporting behavioural requirements of dispatch workstation task handling. The author use the well-studied and robust Fitts' Law for measuring and analysing user behaviour with NUIs. Evaluation of the prototype system finds that the multi-touch system paired with the multi-monitor system was the most responsive of the interaction techniques, direct or indirect. Based on these findings, employing such an interaction system is a viable option for deployment in FMS's. However for optimal efficiency, the firmware that supports the interactivity dynamics should be re-designed so it is optimized to touch interaction. This will allow the multi-touch system to be used effectively as an affordance technology. Although the gesture interaction approach has a lot of potential as an alternative NUI device, the performance of gesture input in this experimental setting had the worst performance of all conditions. This finding was largely a result of the interface device limitation within the wide FOV display range of the multi-monitor system. Further design improvements and experimentation are proposed to alleviate this problem for the gesture tracking and for the touchscreen modalities of interaction.
