DDP(discovery-driven prototyping) is a user-centered prototyping approach originally proposed by Youn-kyung Lim and her co-workers. The core idea of DDP is to provide clear functionality without pre-defined purpose-of-use and use contexts so that users by themselves could discover unexpected value of the given functions in their own lives. This research program develops and examines DDP particularly in the domain of domestic ubiquitous computing and personal life care.
It has always been challenging for designers and developers to readily pinpoint potentially viable opportunities for emerging technologies in people's daily lives. In ubiquitous computing in particular, the uncontrollable dynamics of a user's context makes this issue even more prominent. In this article, the authors assume they can't hypothesize what users of new technologies will desire. To address this challenge, they developed discovery-driven prototyping, which lets users control what they will do with new technologies. Here, the authors describe DDP and its effectiveness through a series of in- situ user studies.
