All the navigation buttons do not use text. They're more like controls on a video recorder than a computer. Structure Insects has a main menu which offers six activities. Each of these activities is no more than 3 layers deep. Navigation controls remain on the screen at all time and respond consistently so that it is easy to jump back to the main menu from any point in the program in one step.
Help is always available and is context sensitive.
Each of these arm were arrived at by analysing the resources we had and deciding the best way to present them. This was to be the main part of the project. We had the pick of literally thousands of insect slides taken in the field and in the studio over the past thirty years. Approximately three hundred of these were chosen based on aesthetics and interest level rather than a need to be exhaustive. We were very fortunate in getting the cooperation of Kodak Australia who scanned the slides with their Photo CD system, which, at that stage, had not been released in Australia.
