ABSTRACT
In the previous two chapters the practice of eco-driving was investigated through the use of two distinct methodologies; an online survey of 321 respondents, and the verbal protocol analysis (Ericsson and Simon 1980, 1993) of 19 participants in an on-road setting. The first of these chapters was a general investigation of eco-driving as a concept, and of the perceptions, attitudes and knowledge the general public have of it; it was not specifically intended to inform in-vehicle information design. Chapter 4, on the other hand, was motivated by such a goal. In particular, it was hoped that revealing the cognitive strategies of those that exhibit behaviours characteristic of efficient driving would help guide the design of a system that supports such behaviours in those that do not spontaneously exhibit them. This goal was not attained; this chapter therefore moves away from looking at the cognition and behaviour of individual drivers, and returns to the design framework introduced earlier in the book, that is, Ecological Interface Design (EID).
