Case 7: Designing iPhone user interfaces

Think-Design-Test-Create

• Description

Your supervisor, Ms. Miller, has taken you aside and asked you to begin working on an application for the Hawk Watch organization. This application will be used by grade school and junior high students in the field to count the different types of raptors found in the central flyway that includes Montana, Idaho, Utah, and Arizona.

The interface needs to be simple and usable with minimal additional instruction.  They have decided on the iPhone as the platform that the application needs to run on.

The application will need to be able to record the raptor type, the GPS location, and the time of the observation.  You realize that the GPS and time information need not be input by the user.

Your boss informs you that you will need to present use cases and a storyboard within the week and a prototype soon after that.

• Deliverables
  1. Use cases for your proposed application
  2. A story board for the application
  3. A prototype that uses Dynamic HTML to mimic the functioning application
  4. A similar case
