User interface design for keyframe-based content browsing of digital video

摘要: With the technological advancements in computing and networking today, many interesting potentially useful applications are being developed turned into products. Digital video is one of those application areas that getting more attention as consumer market likely to be huge, including professional editing home entertainment. However, most digital systems so far have been based on technologically ideas possibilities, thus providing very little usability poorly designed user interfaces. Having no long-term base or usage context make it difficult develop a new system using user-oriented methodology where target specification made accordingly. In this research, design interface studied depth, particularly focusing keyframe-based content browsing By analysing identifying important elements designing interfaces, we construct welldefined "design space" specific can by simply selecting set available options. This analytic approach makes design, which clarify due its fuzzy nature, much systematic manageable. The usefulness constructed space demonstrated diverse devices such desktop PCs PDAs (Personal Assistants) sharing same data, also characteristics users. Specifically, browsers suitable for PDA designed, various supporting different preferences implemented space. A qualitative evaluation conducted improve their gain further insights refine underlying
