How to Design User Interface for iPad Applications
Matt Legend Gemmell held a 6-hour workshop at NSConference in both the UK and USA recently, focusing on software design and user experience.
Predictably, an extremely popular topic was the iPad, and how to approach the design of iPad applications. He gave a 90-minute presentation on the subject to start each workshop, and he is very kind to share some of his observations of iPad Application Design.
This article is about the user interface conventions and considerations which apply to creating software for the iPad platform and touch-screen tablet devices in general. It is not a technical discussion of iPad-related APIs. This is an excellent article for designers and application developers. I am sure you will find it useful too.
