Innovative Application Development for Ubiquitous and Wearable Computing

3.5. Towards a New Form of Developer-User Cooperation 47 developer, not the user, should be driving the cooperation; ideally, with prototypes that stimulate users such that they can better articulate what they really could accomplish through radical innovations. Chapter 4 presents X’treme Prototyping which proposes that the developer starts with the creation of an X’treme Prototype without the user but consults the user in several iterations. The idea behind this approach is that the user gets stimulated by the X’treme Prototype and then can provide much more constructive feedback that goes beyond his daily routines.
