3 Design for Intuitivity Everyone wants to have intuitive User Interfaces No-one knows exactly what it means Everyone has them

4 Intuitive interface designed to make searching fast and easy

5 Design for Intuitivity Intuitive interface allows end users to use without help

6 Definition Intuitivity V1.0 A technical system is intuitively usable if the users unconscious application of knowledge leads to effective interaction.
