데스크탑 어플리케이션이나 웹페이지 서비스를 모바일로 옮겨야 하는 경우 어떤 점들을 고려해야 할까요?
요새 참 고민이 많은 부분이랍니다.
애플 아이폰 휴먼인터페이스 가이드라인에 보니 Bringing a Desktop Application to iPhone OS라는 부제의 좋은 내용이 있어 소개를 해볼까 합니다.
To help you visualize ways you can create an iPhone OS version of a desktop computer application, this section describes some of the design differences between familiar Mac OS X applications and their iPhone OS counterparts.
As you learn about which features and functions in each application were adapted for its iPhone OS version, you will gain insight into the types of design decisions you need to make for your own iPhone application.
Mail is one of the most highly visible, well-used, and appreciated applications in Mac OS X. It is also
a very powerful program, one that allows users to create, receive, prioritize, and store email, track
action items and events, and create notes and invitations. Mail provides most of this functionality in
a single multipane window. This is convenient for people using a desktop computer, because they
can leave a Mail window on the display screen (or minimized to the Dock) all the time and switch to
it whenever they choose. Figure 1-6 illustrates many of the features available in the Mail
message-viewing and compose windows on the desktop.

But when people are mobile, their needs for an email application are simpler, and they want access to core functionality quickly. For this reason, Mail on iPhone OS–based devices focuses on the most important things people do with their email: receive, create, send, and organize messages.
To do this, it displays a pared-down user interface that makes the organization of the user’s accounts and mailboxes clear and centers the user’s attention on the messages.
Mail in iPhone OS is a perfect example of a productivity style application: To ease navigation through the content, Mail in iPhone OS takes advantage of the naturally hierarchical organization of people’s email and displays on successive pages accounts, mailboxes, message lists, and individual messages.
Users drill down from the general (the list of accounts) to the specific (a message) by selecting an item in a list and viewing the things associated with that item. To learn more about the productivity style of iPhone applications, see “Productivity Applications” (page 19).
In addition, Mail in iPhone OS enables actions, such as create and send, by displaying a handful of
familiar controls that are easy to tap. Figure 1-7 shows how Mail makes it simple to view and send
email in iPhone OS. Note how elements at the top of each screen make it easy for users to know both their current and previous location in the application.

iPhoto
Another instructive example of a Mac OS X application that was reimagined for iPhone OS is iPhoto.
On the desktop, iPhoto supports comprehensive searching and organization, powerful editing
capabilities, and creative printing options.
When people use iPhoto on their desktop or laptop computers, they appreciate being able to see and organize their entire collection, make adjustments to photos, and manipulate them in various ways.
Although the main focus of iPhoto is on the user’s content, the application also offers extensive functionality in its window. Figure 1-8 shows the iPhoto user interface on the desktop.

But when they’re mobile, people don’t have time to edit their photos (and they don’t expect to print them); instead, they want to be able to quickly see and share their photos.
To meet this need on iPhone OS–based devices, Apple has provided the Photos application, which
focuses on viewing photos and sharing them with others.
The Photos user interface revolves around photos; so much so, in fact, that even parts of the device user interface can be hidden.
When users choose to view a slideshow of their photos, the Photos application hides the navigation bar, toolbar, and even status bar, and displays translucent versions of these elements when users need to see them.
Photos makes it easy for users to organize and find their photos by using a hierarchical arrangement: Users select an album, which contains a collection of photos, and then they select a single photo from the collection.
In this way, Photos is an example of an application that combines features of the
productivity style and the immersive style (to learn more about these styles, see “Three Application
Styles” (page 19)). Figure 1-9 shows how users can view photos in the Photos application.

In addition, Photos uses a transient view, called an action sheet (described in “Alerts, Action Sheets, and Modal Views” (page 63)), to give users additional functionality without taking them out of the photo-viewing experience. Figure 1-10 shows how Photos provides options for using an individual photo.

Mail의 경우, create, receive, prioritize, store, track action items and events, create notes and invitations 등의 기능들은 receive, create, send, organize로.
iPhoto의 경우, searching and organization, powerful editing capabilities, and creative printing options. 등의 기능들은 viewing, sharing 으로 mobile에 특화된 점을 보실 수 있습니다.
역시 cross-platform에서의 UI성공여부는 해당 Context에 대한 명확한 이해 없이는 성공할 수 없는 것 같습니다.
