Most 3D modelling software have been developed for conventional 2D displays, and as such, lack support for true depth perception. This contributes to making polygonal 3D modelling tasks challenging, particularly when models are complex and consist of a large number of overlapping components (e.g. vertices, edges) and objects (i.e. parts). Research has shown that users of 3D modelling software often...
Visualisation and structuring of tasks in a schedule, from relatively simple activities such as meeting scheduling to more complex ones such as project planning, has been traditionally supported by timeline representations similar to Gantt charts. Despite their popularity, Gantt charts suffer from a number of shortcomings, including poor representation of detail and inefficient use of screen real-estate,...
Since April 2008, a "digital inclusion" research cluster gathering researchers and professional practitioners from British universities and industry has focused on discussing and developing methodologies to increase the accessibility of digital systems to "digitally disenfranchised groups", including special needs and elderly users. We here report on the Ontologies and Interactive...
Despite its popularity and widespread use, timeline visualisation suffers from shortcomings which limit its use for displaying multiple data streams when the number of streams increases to more than a handful. This paper presents the Temporal Mosaic technique for visualisation of parallel time-based streams which addresses some of these shortcomings. Temporal mosaics provide a compact way of representing...
Accessing specific or salient parts of multimedia recordings remains a challenge as there is no obvious way of structuring and representing a mix of space-based and time-based media. A number of approaches have been proposed which usually involve translating the continuous component of the multimedia recording into a space-based representation, such as text from audio through automatic speech recognition...
Although digital recording of speech is widespread, and an increasing range of applications allow recording and inclusion of speech data in documents, editing and retrieval of speech audio remains generally a challenging task. We have previously developed a speech audio editing and browsing application which utilizes imperfect transcripts of speech as a mechanism for text-based editing and retrieval...
