Smoke and mirrors: gathering user requirements for emerging affective systems

Emerging technologies, such as affective computing, have potential to enhance human-computer interaction (HCI). They are still at a prototype stage and effective working systems are still some years off. The problem is that much development is driven by what is technically possible at this time, rather than by what users require. By using Wizard-of-Oz (WOZ) methods to simulate a working affective system, it is possible to examine some user behaviours and preferences with such a system
