Now, it’s your turn
Name (pronunciation if non-obvious) Major, Year Interests Why UI SW

What is this class about?
Organizing principles of UI software
Practice in UI implementation

Part 1: Traditional 2-dimensional GUI
Part 2: Advanced topics

What this class is NOT about
User-centered design
That is 4750 (and Beki G’s new course).

Basic Course Info
“Prerequisite”: CS 4750
Web materials
General info (books/readings, exams, homework) Related classes syllabus (thematic organization)
Will be updated Will contain some lecture slides

6 homeworks (milestones): 6 x 10% Midterm: 20% Final exam: 20%

Homework assignments will use the .NET Framework and C#

What you turn in must compile and run.

Important note
There will be minimal C# / .NET training in class. If you are not comfortable with C# / .NET programming:
1) Learn 2) Drop course

Most systems are built for a user.
Good “user interfaces” are critical for software survival and economics. Designing for users is important and difficult, and requires iteration.

Motivation for developers
It is necessary to have tools for:
rapid prototyping (quick feedback) iterative development (rapid response)

of (semi-) functional systems.
As we move “off the desktop” the tools we need to develop change.

What is the User Interface?
Since mid-40s
Since late ’60s
Display Keyboard

Since early ’90s

pointing device WIMP/GUI

An extension of our physical environment

Programmer’s Perspective
The “UI” is typically viewed as one component of the overall system
The part that “deals with the user” Separate from the “functional core” or “application”



Software Engineering the UI
Separation of concerns
UI from app Isolate changes Leads to more modular implementation Will see other specific examples

Sometimes a conflict
Rapid feedback / performance

Basic parts of the UI

UI Core

App Interface



Understanding “traditional” GUI
Output & Input
Technology and programming models

Interaction models and architectures
Toolkits and programming environments

Advanced topics …
Multiscale input and output
“Natural” interaction types Sensing-based interfaces Paper technologies Intelligent environments Requests?
Audio, video, pen Large surfaces, handheld, wearable

Recognition, context-awareness
