Forum Theatre as a requirements gathering methodology in the design of a home telecommunication system for older adults

The ability to elicit requirements in the design of new technology has proved to be particularly problematic with older generations of users who have not grown up with the same level of familiarity and understanding of present day user interfaces as younger generations have. It is also widely acknowledged that older people are poorly represented in the development process of mainstream technology. In this paper, we critically examine how 'Forum Theatre' can be used as a requirements gathering methodology in the development of a novel digital television (DTV) based communication system. We demonstrate how live theatre established a 'common ground' between audience participants and actors in the facilitation of new ideas, and discuss how live theatre can be used to stimulate interest and understanding from designers and relevant professionals in the development of an unfamiliar and largely undefined technology for older adults.     

多维网络论坛数据的层次可视化

多维数据的可视化可以帮助人们在有限的时间内快速理解和分析海量数据集。网络论坛数据具有复杂性和大规模性,无法采用简单的图形显示出隐含的规律。针对多维海量论坛数据,首次分析了论坛数据的特点,然后提出了一种层次的数据组织方式,进而针对论坛中的主题时变分布、热门主题转换、作者回复关系等多种数据信息,采用平行坐标、曲面关系图、层次映射图等多种形式进行海量论坛数据的互动可视化。最后以实际论坛数据为例,给出可视化结果并进行分析。
