Multitouch represents a fundamental shift in the way we interact with computers and digital exhibits. Interaction on multitouch devices is more physical, intuitive and social than the traditional mouse and keyboard. These advantages also present new design challenges. This tutorial highlights the main differences between the multitouch and point-and-click paradigms. It presents the range of interaction styles and interface elements available to designers of multitouch applications and suggests ways these can be combined to create a user-friendly exhibit. Especially if you have not worked with multitouch or multiuser applications before, this is the place to start.
