Abstract
Like much of modern technology the space of possible iTV applications and designs is conditioned by rapid developments in the platform capabilities. Finding likely take-up within a single generation of this technology is difficult, and feedback may only come through live testing, in which an application is offered up in hope and judged on the response that comes from the viewing public. Projections to the next generation of technology suggest an ever-wider space of possible application and users (Close to six million people have access to digital television in Britain). This paper addresses the problem of finding or discovering requirements for new applications, both at the macro level (the nature of the application) and the micro level (the way in which the service is presented and interacted with). We assume the goal of establishing a firm theoretical footing for specifying services at both levels, and finding appropriate techniques for bringing theory to practice. We describe knowledge-spaces that can be explored by designers seeking to specify applications and support them with appropriate design practice. We argue that exposure to iTV packages, television, other technologies such as PCs and mobiles primes potential users with tacit, semi-tacit or semantically distanced information that can lead designers to design worthwhile and successful applications. Furthermore, even where an individual has little exposure to technology they possess information about lifestyle, preferences, and latent task-support wishes that may be buried and only accessible with the appropriate technique. The paper further investigates the role of metaphor and semiotic analysis in linking from the latent potential for a service or application to its realization in a user-acceptable design. The final part of the paper suggests ways in which we can expand and focus the use of knowledge elicitation tools dependent on which of the factors cited above we wish to explore. We believe that rich elicitation from users and potential users is an ongoing process that will help focus design and delivery of iTV products.
