Need summary of below case.

Case Study 2 examines the process and decisions reflected in an Apple document titled From Desktop to iOS (Apple, 2015a, 2015b). In this analysis, Apple examined products and design decisions made for Keynote (for presentations), Mail (e-mail for iPhone), and web content.

The case study reviews style guidelines from the Apple Development Guide- lines and how these were applied in bringing apps to iOS-enabled devices. For more information on related issues, see the iOS Human Interface Guidelines in the iOS Developer Library that Apple provides (Apple, 2015b). Following are a few samples of the referenced iOS Human Interface Guidelines (explanation, use, and screenshot illustrations are given for the guidelines):

There are guidelines for icons and image design, iOS technologies, user inter- face elements, and more.

Keynote has presentation development tools, graphics and toolbars for rapid generation of presentations.

Presentation (graphics) styles as well as human interaction for touchscreen devices are included in the case study, illustrating the products ease of use. iOS deviceenabled features apply direct manipulation and gesturing interaction (see Chapter 7) that are easy to use.

Next the Apple study looks at Mail for iPhones. Fig. 6.3 illustrates Apples intuitive, predictable navigation for Mail that has a user interface consistent with the Apple product line.

The case study finishes with a discussion on Safari on iOS devices, where again the mobile web-viewing user experience on iOS devices is easy to use and consistent with the product line and gives web designers valuable insight as to the portability and ease of development of web content for iOS devices. References to iOS Design Strategies consistent with the teachings in this text are includedspecify the app, determine who the users are, identify desired fea- tures (requirements collection), preliminary and detailed design, build and development, evaluation and testing.

Observations

Some general observations are worth noting with respect to this case study. The years of experience with the referenced Apple Human Interface Guidelines are brought to bear on the problem. There is a consistent style across all products

and devices that makes device operation comfortable and intuitive. Rapid device technology improvements (lighter weight, faster, more colors, more pix- els, improved throughput, etc.) result in a constant reevaluation of the user interface and improvements of the guidelines applied. Still, the principles dis- cussed in this text also hold true in this case study: universal usability, guide- lines based on principles and theory, iterative user-centered design processes, and a keen appreciation of the user experience and of style.

The following case study shows a successful collaboration in a large cor- poration utilizing user-interface development process methods to solve a data-analysis challenge.
