iPhone App Design: A user-centered approach
This document discusses user-centered design for iPhone apps. It describes common issues people have using their iPhone apps, such as tasks requiring too many steps or apps not syncing properly. It then provides recommendations for designing iPhone apps, including conducting upfront user research to understand user needs, brainstorming and sketching design directions, and refining and testing promising designs through usability testing. The goal is to design intuitive apps that solve users' problems in an efficient manner.

- 11. What can youdo?
- 12. #1: Conduct upfrontuser research Upfront user research will help you better understand your usersโ needs. Research will help you make informed design decisions; you may also uncover fascinating app opportunities. Methods to consider: Shadowing, Field Interviews, Diary Studies
- 13. #2: Brainstorm &sketch like mad Explore a wide variety of design directions early on. Read Appleโs Human Interface Guidelines for the iPhone, but try to see beyond the basic frameworks. Learn whatโs possible with the iPhone technology and consider ways it can benefit the user experience.
- 14. #3: Refine &Test Promising Directions Usability testing your concepts will help uncover issues related to setup, flows, terminology & more. Alternative approaches: - Paper prototypes - Screenshot based prototype on the iPhone - Interactive prototype on the iPhone
- 15. Thank you &good luck! Suzanne Ginsburg @suzanneginsburg Also thanks to Michelle Reamy for her user research work in NY: michelle@michellereamy.com
Editor's Notes
- #3ย These stories are based on user research conducted in the fall of 2009 by Ginsburg Design and Reamy Research & Design. Diary studies were combined with field interviews with 12 participants in New York and The Bay Area.
- #4ย This participant used to have a laptop (iMac) and a mobile phone. When her laptop broke she was torn between replacing the laptop and getting an iPhone. In the end she decided to get an iPhone since she has access to a desktop computer at work. In these photos, you can see a variety of ways that she uses the iPhone at workโto take pictures of framed photos to send to clients and to check if paintings are level. Other apps she likes to use at work include converter and translation apps.
- #5ย This participant is a sophmore majoring in Chemistry. While heโs very busy with school, he also holds two part-time jobs: one at a hotel, another as a private gymnastics instructor. From the minute he wakes up, he uses his iPhoneโitโs his alarm clock! Sometimes heโll lay in bed for a little while as he checks email, the weather, his calendar. On the way to school, heโll use other apps for checking the various bus and trains schedule. At school, he uses a variety of apps, e.g., the periodic table (above), graphing calculators, and a whiteboard app for collaboration.
- #6ย This participant mostly uses the built-in apps on the iPhoneโthe calendar, email, photos, camera. When she goes to the flower market, sheโll use the Notes application to run through the list of flowers she needs to buy. She often takes photos of plants and flowers to send to clients. Even though the quality isnโt the best, itโs โgood enoughโ as a communication tool. Sheโll use her SLR or hire a professional photographer if she needs something of higher quality.
- #8ย Participants often cited issues with setting up and/or registering for iPhone apps. For example, this Accuweather app takes 3 steps before you even see any weather. Having the โTerms of Useโ upfront is far from welcoming for first time users. Two participants said they really wanted to use this app, but gave up since it was too complicated to get started. They ultimately deleted the app from their phones.
- #9ย Participants also cited simple tasks taking much longer than they expected. For example, adding a to do item for the app above takes 5 steps. In contrast, the built-in Notes app takes just one step.
- #10ย Participants expected apps to behave a certain way based on their experiences with a desktop or web application. This is not to say that iPhone apps should work exactly like their desktop or web counterparts, but itโs problematic when the differences create additional work or dead ends for users. For example, the built-in calendar doesnโt synch to do items on the phone, thus the participant (first image) added the items as all day events.
