This chapter introduces the main trends in the design of interfaces for smart wheelchairs. It stresses the importance of taking into account their similarity with autonomous mobile robots and the restrictions posed by the special characteristics of the users (people with severe motor and speech restrictions) and the task (indoor assisted navigation). With this background, the main features of the user-wheelchair interface are discussed, justifying the need for the adoption of an adaptive approach. The TetraNauta smart wheelchair interface design is used to illustrate the design of user, context, and task models. In addition, it describes some mechanisms to enhance the communication rate when a single-switch-scanning input device is used (scanning rate dynamic adaptation and word prediction). The chapter finishes with a discussion of the influence of new navigation models, such as the behaviour-based one, in the design of the user interface.

Complex Systems Modeling by Cellular Automata
It is a description of naturally observed phenomena using analytical, numerical, and/or computational methods. Computational modelling is classically used in such fields as, e.g. physics, engineering. Its importance is increasing in other fields such as biology, medicine, sociology, and psychology.

State-of-the Art Concepts and Future Directions in Modelling Coordination
The representation of a real world object or system in a mathematical framework. In such way software tools can be used to imitate the operation of the real world system over time so that inferences can be drawn about potential future outcomes.

Use of Hydrogen and Fuel Cells for Refrigerated Transport
A computer model refers to the algorithms and equations used to capture the behaviour of the system being modelled. This enables to determine some behaviour or property of the original system avoiding the need of performing real tests. The external data requirements of simulations and models vary widely. For some, the input might be just a few numbers (for example, simulation of a waveform of AC electricity on a wire), while others might require terabytes of information (such as weather and climate models).

Vicarious Learning
In the sense used by e.g., Bandura, the way in which a person’s behaviour will tend to be modelled or patterned on behaviour that they observe. This may take a relatively individualised form, but is often seen and studied in social behaviour, where in particular vicarious learning processes may play a role in modelling.
