Abstract

We developed an inquiry technique, which we called "paratype," based on experience prototyping and event-contingent experience sampling, to survey people in real-life situations about ubiquitous computing (ubicomp) technology. We used this tool to probe the opinions of the conversation partners of users of the Personal Audio Loop, a memory aid that can have a strong impact on their privacy. We present the findings of this study and their implications, specifically the need to broaden public awareness of ubicomp applications and the unfitness of traditional data protection guidelines for tackling the privacy issues of many ubicomp applications. We also point out benefits and methodological issues of paratypes and discuss why they are particularly fit for studying certain classes of mobile and ubicomp applications.
