Một số ứng dụng có thể không được nhập vai rất thích hợp với các phương pháp vẽ mô tả. Ví dụ, storyboarding một loại nhạc cụ với bút và giấy là mất tích xác định nguyên tố của nó âm thanh! Điều đó nói rằng, các phần khác của ứng dụng của bạn có thể hưởng lợi từ quan đại diện trực quan, như các kinh nghiệm sử dụng lần đầu, cài đặt và hướng dẫn. | FIGURE Sketches exploring gestures for a personal finance iPhone app Courtesy of Marcin Ignac FIGURE Sketches exploring an answer selection for a quiz iPhone app Courtesy of Jason de Runa Common Questions 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. Answers to these questions and others are covered in this section. WHAT IF I M WORKING ON AN APP WITH FEW VISUALS TO SKETCH Certain immersive apps may not be well suited to the sketching approaches described. For example storyboarding a musical instrument with pen and paper is missing its defining element sound That said other parts of your app may benefit from visual representations such as the first-time user experience settings and tutorials. Sketching these elements can be effective for almost any type of app. Alternatively you may find that these elements are too interwoven into the overall app experience. In this case you may want to jump right into prototyping which will be discussed in the following chapter. WHEN SHOULD I CREATE FLOWCHARTS Flows are an incredibly important part of the iPhone app design process but I recommend starting with one of the sketching approaches introduced in this chapter. Once you have explored alternative directions and narrowed down your options we ll discuss the narrowing part in the next chapter move on to flowcharts. If you begin with flowcharting software you may get into edge case resolution mode as you branch every possible outcome. Don t get me wrong solving edge cases is critical but not in the concept stage. 128 CHAPTER 6 EXPLORING APP CONCEPTS Download from HOW MUCH OF MY DESIGN TIME SHOULD BE DEVOTED TO CONCEPT DEVELOPMENT Every project is different but try to allocate at least 20 percent of your overall design time to concept explorations. Having a solid concept will help make the rest of the design process .
