WhyThisClass?

“I like creativity and as much as I hate to say it, looks do matter. I believe

that a visually appealing application that is intuitive, has a short learning

curve is the most appealing to the users of the application. I hope to learn

how to make my future application this way.”

“I want to learn how to make software more user-friendly, so the older

generations will not have a problem using the software.”

“I am taking this class because interface design is an incredibly important

part of creating software and applications.”

“I believe one of the most important parts of making software, whether a

simple tool or a game, is making sure that the user can understand it and

easily use it to it's full potential.”

It looked like it might be a bit different to have a class focused on usability and interface, since most of the other classes don't really deal with that. Also, it was in a convenient time slot.

For Example…

The following example is from my Phd dissertation

But also useful as a case study to illustrate iterative design

are the most water consuming

activities in the average North

American home?

Title

How much water do people think

common activities actually use?

Water Usage Estimates (N=656)

3.5 gpm

35 gallons

2.5 gpm

25 gallons 3 gpm = 180 gal

4 gpm = 240 gal

5 gpm = 300 gal

What makes this even more surprising is that the individuals surveyed were greatly interested in water conservation!

88% interested in conserving water at home

84% try to limit their water usage

[Kempton & Layne, Energy Policy, 1994]

What if you could

get the same level

of feedback in the

home?

kitchen sink 28 gallons

refrigerator 0.3 gallons

dishwasher 6.5 gallons

Today‘s Usage

toilet 78.4 gallons

shower 62.4 gallons

bath 6.5 gallons

bathroom sink 1 4.2 gallons

bathroom sink 2 0.8 gallons

Today‘s Usage

toilet 78.4 gallons

bathroom sink 1 1.2 gallons

bathroom sink 2 0.8 gallons

shower 52.4 gallons

bathroom sink 1 3.2 gallons

Today‘s Usage: hot vs. cold

Traditional water meters measure

aggregate consumption

Requires

cutting into

pipe to install

• Single, screw-on sensor

• Identifies fixture usage

• Estimates flow

What can we do with this data?

This is an interface design problem!

MetaphorView

SpatialView

Per-Occupant View

TimeSeries Day View

We also explored more ambient

displays that were less “data-centric”

and more fun and playful

“Frank” the fish

meets his mate

Frank and his

interactive so

ProjectOverview Goal: Apply and integrate user-centered concepts learned in this class along with your

other (current and prior) computer science education.

Secondary Goal: Work on real problems! Intense end-to-end design.

Focus: Social value applications (i.e., applications that are targeted at improving a

person or persons health, welfare, and/or everyday life)

Teams: Divided up based on skills and interest. If you have a significantly good

practical reason for working with someone, let me know.

You must be committed to working with your team throughout the semester.

I would rather you spend more

time picking a good project and

leaving less time for final

implementation than the

alternative.

ProjectChallenges Time management

Teamwork and equity

Not getting wedded to an early, suboptimal idea

Coding

Too Early!

"The first 90 percent of the code accounts

for the first 90 percent of the development

time. The remaining 10 percent of the code

accounts for the other 90 percent of the

development time." -Tom Cargill, Bell Labs

UnderstandingPeople

TaskAnalysis

You’ll define three tasks specific to your problem space

You’ll create storyboards and prototypes around those tasks
