The amount of multimedia content that is available to the general population has steadily increased in recent years and this brings with it the challenge of managing large quantities of content; for both creators and consumers. The MPEG-7 standard is aimed at facilitating the management of multimedia content by providing a set of standardized tools for describing audio-visual information to support a wide range of applications. This paper describes the development of one specific application that allows consumers to access a large video database of football video footage using a mobile device. Development has followed a user-centred methodology to ensure that the application development is driven by user needs rather than by the MPEG-7 technology alone.
The process began with scenario-based design to create a broad use scenario from which initial user requirements and unctional requirements were derived. Functional requirements were grouped to correspond with particular user goals and the system was modelled according to Beyer and Holtzblatt’s ’user environment model’ which creates a system view from the user’s perspective. This model was then used as the basis for the user interface design for a mobile device. The design process is not yet complete so the paper presents the first phase of work to meet the needs of a specific group to search for sports footage using MPEG-7.
