Human-Computer Interaction. Neema Moraveji SAMS-CS 2003. Do these look familiar?. Are these the best ways? Maybe. Probably not. They are still improving. People keep trying to make the desktop easier to use!. Applications. Which one is better?

Are these the best ways?Maybe. Probably not.They are still improving.People keep trying to make the desktop easier to use!
Which one is better? We would have to find outby running experiments. One is not necessarily betterjust because it looks ‘cooler’.
Pretty cool and funky looking!But have you used this before?
Allow me to introduce… • User Interface (UI) • What is UI? • “CS” definition: • “visible piece of software which makes the services of the underlying system easier to utilize efficiently (and effectively)” • Neema’s definition: • “The way in which a piece of software looks, behaves, and reacts to the user.”

UI research is a cool and importantpart of computer science!
What’s HCI? • People who study UI are in the field of Human-Computer Interaction (HCI). • They figure out how to make hardware and software UI effective, efficient, and easy to use • It’s a new field that is becoming extremely important and changing quickly.
Why is HCI Important? • One might ask, “Does it really matter? As long as the software works, who cares what it looks like?” • One reason Windows won ‘the war’ was because it improved the UI. • High quality software has people working to create a fantastic user interface.
Let’s look at the mobile phone • All devices present new constraints • What are some constraints in these cases?
Let’s look at the mobile phone • All devices present new constraints • The mobile phone is very small, how do we provide information while still making it • easy to read • easy to use while in motion • usable with one or two fingers • attractive
Let’s look at the mobile phone • All devices present new constraints • The mobile phone is very small, how do we provide enough information on such a small screen while still making it • easy to read • easy to use while on the go • usable with one or two fingers • attractive • Not one pixel can be wasted!
