I'm designing an interface based on data gathered from users. It is for a website which allows you get advice on choosing a restaurant. I'm stricly following a textbook which says you must identify the 'concepts' within the system for effective design but doesn't give clues as to how to do so- I was just wondering what types of thing would be considered a concept. Another textbook describes an ambulance dispatch service and identifies two of the concepts as being 'the incident' & 'the phone call' to the ambulance dispatch. I can't seem to effectively transpose this idea for my task. Can anyone recommend anything based on experience? Or even a definition for a 'concept' regarding systems in HCI?
Haven't read your textbook obviously, but i think it's important to think what data goes into the site and what comes out (will be displayed). For this example i'm thinking about concepts like "restaurant", "user review", "restaurant rating", "cuisine". But it all depends on how your website works ofcourse.
