Abstract
Although video has been used for many years to record data, few tools have been developed to manipulate or enhance video data. Current multimedia interfaces have severe cognitive and attentional limitations, reflecting technology-centred designs which have not profited from human factors theory and user-centred design. This results in cumbersome and expensive systems with serious usability problems. This paper describes a prototype Video ANNotation and Analysis system (VANNA), which integrates video, non-speech audio, voice, textual and graphical data, and which incorporates emerging technology, user-centred design and human factors theory.
