What is the iPhone?

The iPhone is an integrated cellular telephone and media player developed and marketed by Apple. The device combines the main functions of several popular electronic gadgets in a single device, with a shared interface and integration between them. In addition to its primary function as a cellular telephone, the iPhone includes a music and video player, digital camera, PDA, and an Internet communications suite. Although the iPhone runs Apple's OS-X operating system, the device is not expected to run all OS-X compatible software. Additionally, the phone lacks certain cutting-edge features expected in any new state of the art cellphone, such as 3G connectivity and a user-replaceable battery. Rumors of the iPhone have catalyzed the founding of iPhone forums, wikis, and communities long before the device was formally announced.ApplePDAInternetoperating systemsoftware3G The iPhone makes extensive use of data and hardware synchronization between its individual components. When used as a media player, the volume of the current song fades down as a phone call is received. Similarly, the music fades back to its previous volume when the call ends. The camera can be used to make video calls in addition to still and video pictures, and pictures taken with the camera can be used to identify contacts in the phone book. The bluetooth connectivity can stream either music or calls to Apple's redesigned bluetooth headset. Additionally, the iPhone's touchscreen was specifically designed to control all the device's functions without the need for a stylus.datahardwarebluetooth

Five iPhone users with a range of experience from intermediate to advance participated in the usability test for the Apple iPhone interface and default applications. In general, people found the iPhone to have an aesthetically pleasing interface with an intuitive design. Overall, satisfaction level as rated by the users averaged 4.4 out of a 5 point scale (5 being the highest level of satisfaction). The majority of issues noted about the iPhone interface by the users involved customization of the organizational structure and interface layout.

The most important observation learned through the testing is that although there are improvements that could be made to increase performance and efficiency, overall the evaluators found using the iPhone to be easy and fun. All except for one task could be completed by the users relatively quickly and with limited mistakes. Because the goal of the testing was looking for issues that hindered performance or efficiency in completing tasks within the iPhone interface and default applications, the problems found with the product are being magnified.

usability testing was focused on the 22 to 39 year old iPhone user segment. WHOM had the general goals to improve their productivity and stay socially connected. These users strive to stay connected with news and newly developing trends. Staying current and informed is of the highest value to this user segment.

Each of the testing situations was be conducted in a reserved private room inside the Richardson Library in Lincoln Park, Chicago. Both the test subject and moderator sat on the same side of a table with the observer/recorder standing/sitting behind the test subject at a listening distance

Included note taking and time reporting on each task The test monitor remained out of the test subject(s) line of sight for the duration of the usability test. The recorder simply took notes on the observation of the users interaction with the Apple iPhone. In the perspective of the test subject, the recorder was introduced and made aware of to the participant but no further interaction will took place.

The test metrics that were used to assess usability for the Apple iPhones default applications were efficiency, memorability, errors, utility, and overall satisfaction. Both qualitative and quantitative data were used to measure the usability of the iPhone. The quantitative data will measure the time on task, the accuracy of task completion, the number of clicks for task completion and any errors encountered. The qualitative data was measured by recording the users hesitations, phases of confusion, and emotional response. All measurements were recorded during the usability testing using the usability test log. The overall satisfaction of the product was measured both during the test and with the post-test questionnaire.

We would have had an computer record the click and time of each task To rule out user error of the observer Possibly a more detailed script of slow down and speed-up questions to keep the participant motivated throughout the Usability Test. Even though, the moderator, Kelly, did a great job with keeping the user involved some minor leading comments could have been omitted.
