User Experience

The tab bar is better on the iPhone, iPhone users prefer applications over

websites.Read-tap asymmetry exists due to

the fat finger.

The usability of iPad applications was tested.

The participants were 7 iPhone users, one with previous iPad experience.

Popular applications tested include: ABC Player eBay IMDb Yahoo! Entertainment

The first image map was created in 1993. Any part of any picture is a user interface

element. There are standard Graphic User

Interface (GUI) guidelines. The iPad utilizes an “etched-screen

aesthetic.” Users do not know where to

click There is no visual distinction.

Each application works differently. iPads do not have an undo button

(i.e. browser’s back button).

Touching a picture Nothing happens Image is enlarged User is taken to

another page Image flips to

reveal other images

Navigation options pop up

Continuing to read Scrolling down Swiping left Swiping up

Electronic Media: Users do not have a homepage to select

from. Users must swipe to move from article to

article.

Two hypertext models exist. Card sharks: fixed canvas (iPad

applications) Holy Scrollers: infinite scrolling (the

Web)Users want scrolling.

Will the iPad attract crowds other than the entertainment-oriented?
