Chapter 2: Trends Towards Mobility 43 music store. The store offers background information on the artists and their albums, conveniently linked for random access. It maintains a history of the users’ purchases and manages the digital rights related to the downloaded fi les. In essence, the song that the user enjoys on the road is just an end-product of this sophisticated content manage- ment chain. The notion of a song is then, in a way, changing to repre- sent the whole chain, not just the end-product. As mobile music has transformed via various steps into today’s bit collections, users’ control over their music has increased with every 29 step. With such freedom, dealing with the music has mutated from physical manipulation into digital information management. Music can now be conveniently handled in the fully digital domain, with the artefact (the song) only residing as a series of bits in a memory device. This has caused some discomfort to people who would prefer to hold music as physical artefacts. Such people often like to burn downloaded music onto CDs (and print the covers), just for being able to touch the artefact and admire cover art without the use of computers. Other forms of media (video, books, news) are undergoing similar transformations from analogue to digital, creating ever greater needs for content management. People are becoming IT department manag- ers in their digital content warehouses. They are facing the associated digital diffi culties – but also the added digital freedom. Our goal is to design content management in such a way that enjoyment is maxi- mized but the need for management is minimized. This book hopes to uncover some ways of achieving just that. 2.8 References Bergman E. (ed.) (2000) Information Appliances and Beyond: Interaction design for Consumer Products.
