FIGURE 2.16 Google Search activates voice search using the proximity sensor.. The accelerometer can detect the iPhone’s orientation and adjust the display accordingly. Perhaps the most practical accelerometer feature is the ability to change the display from portrait to landscape when the iPhone is rotated. FIGURE 2.17 Marble Maze uses the motion sensor to move the silver ball through the...

User Research. USER RESEARCH CAN HELP you acquire a deep understanding of your users’ needs and how these needs are being met. This chapter will review a variety of user research methods such as. After reading this chapter, you should be able to develop and execute a user research plan for your own app. “Analyzing User Research,” will subsequently explain...

If you go with this approach, instruct the note taker to focus on the interview dialogue. This photo can be added to the “participant profile,” which will be discussed in the next chapter. As mentioned earlier, audio is an effective backup, especially if you have hand- written notes. You may also want to use audio to reinforce a particular finding...

58 CHAPTER 3 ● INTRODUCTION TO USER RESEARCH. In addition to stating the high-level purpose and objective of the study, it’s help- ful to list the questions you want to explore when you meet with participants.. Early-stage user research questions typically focus on user needs, but the questions can also be specific to your iPhone app. Consider the purpose and...

68 CHAPTER 3 ● INTRODUCTION TO USER RESEARCH. The user research strategy depends on the type of app and its stage in the devel- opment cycle. In most cases, apps in the very early stages will benefit from observational methods, whereas apps in later stages will benefit from observa- tional methods combined with app prototypes. Some user research is better...

Example of User Research Findings. When documenting specific user research findings, start with a brief summary such as the one that follows, “Setting Up an iPhone App Can Be Challenging.”. If you have relevant imagery or video, it can also be embedded in the document, as shown in FIGURE 4.4. Setting Up an iPhone App Can Be Challenging Related quotes:....

Location of the evaluation (laboratory versus field). The heuristics you choose can be based on established lists, such as Jakob Nielsen’s heuristics or Bruce Tognazzini’s “First Principles of Interaction Design.” 6 How- ever, in most cases you’ll want to adapt and expand these more generic classics to include specific areas of interest for your app. At a minimum you’ll want...

If you have remote team members, you can send them photos when significant changes are made and follow up with electronic versions to keep everyone on the same page.. If you’re not up for experimentation, you might want to use Leah Buley’s list 1 as a starting point. If you want to get even more creative, I suggest you read...

Nearly all of the popular sketching software programs have iPhone design tem- plates. In most cases, however, your app will contain both standard and custom controls. If you’re working with hand-drawn sketches, you can quickly add the custom items. Balsamiq, www.balsamiq.com/.. For example, if you approach a colleague with a notebook sketch, it will be obvious that the design is...

As you consider which sketching approach is right for your app, you may have some questions about the level of effort and the relationship of the sketches to other design deliverables. In this case you may want to jump right into prototyping, which will be discussed in the following chapter.. Flows are an incredibly important part of the iPhone app...

Prototypes can be an efficient way to work through design problems before getting deep into coding. For example, imagine that you’re creating a messaging app that will display a transition when users move messages from one folder to another: What is the optimal speed of the transition? What is the best form for the visual feedback? How do these two...

ptg FIGURE 7.11 Segmented control example. Here are some additional elements you may need to include:. Users generally understand how the keyboard works, so you can say things like “Imagine that the keyboard would display the text you entered.”. Similarly, if you are preparing a prototype for a study, don’t worry if you haven’t created every single interface element users...

First, we see prototyping as a natural part of the design process, allowing us to capture, communicate, and manipulate our ideas—quickly and fluently. We factor in the usual constraints—time, budget, and scope—but also how the wider development team works and how the prototypes could be reused. A video of the prototype and “how-to”. One of the useful things about Keynote...

Ideally, the RITE user researcher will have experience in the domain and in the problems typically experienced in this domain. For example, when testing one app, we discovered a line of text that prevented participants from moving beyond the welcome screen. Category 2 issues can be difficult to address within the study timeline (e.g., the solution may not be clear)...

178 CHAPTER 8 ● USABILITY-TESTING APP CONCEPTS. As mentioned earlier, it’s critical to run a pilot session to uncover any issues with the prototype or discussion guide. In addition to recruiting a participant based on your user profile, you may want to do a test run with a team member unfamiliar with the app design. The discussion guide will be...

see page 256 Branding the user experience. Now that you have formulated your app concept, the next step is to look at a variety of ways to refine your design.. Chapter 9, “User Interface Design,” includes guidelines for a range of UI issues (navigation, personalization, feedback) as well as best practices for the iPhone UI controls outlined in Apple’s iPhone...
