Design: Create Personas

◼ Easier to generalize about

fictional people
◼ What would Harry Potter do?

◼ General users have too

many conflicting goals

◼ Specific personas have

clear, well-articulated
goals.

Design: Define the Problem

Focus on the problem

- choose the appropriate framing

“bicycle cup holders”

vs
“helping cyclists to drink coffee safely”
Or, helping users track prepaid meter usage
Or, helping graphics designers place virtual objects

Tips for sketching

◼ Don’t stress about quality or if you can draw a straight line, stick figures
are totally fine!

◼ Use squiggles instead of text, boxes instead of pictures

◼ Don’t think, just draw (fast) – give yourself a time limit

◼ You don’t have to finish every picture!

Prototype

◼ Build something tangible

so you can get feedback

◼ Experiment with alternative

designs (cheaply!)

◼ Fix problems with concept and

flow before code is written

◼ Keep the design centered on

the user!

Constructing the Prototype

◼ Set a deadline
◼ Don’t think too long – build it!

◼ Draw a window frame on large paper

◼ Draw larger – but keep the same aspect ratio

◼ Put different screen regions on cards

◼ Anything that moves, changes
appears/disappears
◼ Use squiggles to indicate text if necessary Miiverse cardboard prototype
Kazuyuki Motoyama
◼ Ready response for any user action Nintendo
◼ Pull-down menus

◼ Use photocopier to make many versions

Why not just Hi-fi?

◼ Distort Perceptions of User

◼ Formal representation indicates
“finished” nature
◼ People comment on color, fonts,
alignment

◼ Discourages major changes

◼ Testers don’t want to change a “finished”
design
◼ Designers don’t want to lose effort put
into the design
