Abstract

Product development of innovative new products and applications like digital television is challenging. For new and novel products in general, there is no defined product direction given to the design team at the beginning of the project and there is no clear understanding of user requirements which results in constantly evolving product features. Yet there is a need for new or not-yet-existing hardware and software technologies but no earlier product versions or comparable existing products to benchmark against. User centered design aims to actively involve the users in product development in all phases of the new product design. The limits of user centered design and user research are that the users cannot address any particular future needs without prior experience or knowledge of the subject. Research methods such as usability testing are concerned about existing devices or prototypes but they do not tell directly which new technologies could help meet the users' future needs. New design methods which welcome users' active participation in gathering and interpreting the user data help to shift the point of interest from usability testing in the late phases of usability engineering life cycle to the early phases of product development. Digital television and the new interactive applications enable a transition in the user behavior from straightforward channel surfing to active application usage. This thesis concentrates on user centered design during the early phases of interactive application design for digital television. The aim of research was to find techniques to meet users' future needs and to provide examples of future product concepts. Several techniques were used: a user study based on 'Cultural probes' method, interviews, focus groups, design sessions, usability testing, and storytelling. The work documented here originates from the pre-digital television era in Finland between the years 1998-2003. The author has published her results in seven publications.
