Introduction

Interface Design defines how the system will interact with external entities (e.g., customers, users, other systems) * User interfaces- part of the system with which users interact. * Based on our layers based design approach, the user interface of the human- computer interaction layer is independent of the data management layer. * But it is dependent on both the problem and domain and physical architecture layers. * System interfaces- exchange information with other systems. * Typically designed as a part of a systems integration effort. * Physical architecture and data management layers. * Defines the way in which the users interact with the system and the nature of the inputs and outputs that the system accepts and produces. * Depending on the type of device that the human-computer interaction layer is deployed on will set both opportunities and constraints as to what user interface features can be included. * Ex. Deploying the human computer interaction layer on both a smartphone and a desktop computer will cause two different

6 principles-summarized
““design priniples are”

what are the steps of the user interface
-what is the process
“step 1?”
1st -scenario development
2nd -navigation structure design “whats the purpose” -shows the screens reports, etc
3rd -interface standard design -decided things like interface metaphors, templates, objects, actions, and icons *Know what these mean* and main areas
4th - prototying * The ways its used??
*which one takes the least expertise?
*select the appropriate technique How? - Interface evaluation -What are those four things? (Heuristic, walkthrough, interactive, and formal usability.) * we do three of these things, which one is optional? Class notes *What is Heuristic
