Hardly a day goes by that we don't see an announcement for some new product or technology that is going to make our lives easier, solve some or all of our problems, or simply make the world a better place. However, the reality is that few of these products survive, much less deliver on their promise. But are we learning from these expensive mistakes? Rather than rethink the underlying process that brings these products to market, the more common strategy seems to be the shotgun method, that is, keep blasting away in the hope that one of the pellets will eventually hit the bull's eye. This book's goal is to help with this problem: to inspire and encourage HCI and other design professionals to try new methods, test themselves with the exercises and projects, and see an improvement in innovative interaction design that works. Some of these methods are sketching-based, taking methods that have been traditionally used for design. Others are prototyping methods that have been traditionally used for testing and evaluating design in HCI. The result is a group of methods and process that successfully work in both HCI and design. This helps to give these fields a unity as well as a uniquely innovative way to design user experience. -- Publisher description.
