Visualisations are a quick and powerful tool for data analysis and
information acquisition. Mobile phones are increasingly becoming an
integral tool in our society. Advances in both desktop and mobile
computing and increasing access to Internet access are making information quick to produce
and its availability easy. The result is information overload.
Mobile Visualisation Techniques for Large Datasets
While various techniques for visualising and interacting with
information on the desktop are available, the mobile platform has very
limited resources to cope with information, for example, due to the size
and computing capacity of devices used in that platform. It is therefore
necessary to explore techniques that can assist development of visualisations
in the mobile platform.
The research project aimed to investigate visualisation and interaction
techniques that exist, specifically looking at large datasets of categorical
and map-based data types. From findings on related work, it has been found
that limited resources are a major hindrance to developing effective mobile
visualisations, amongst other factors. A visualisation prototype was then
developed, influenced by the findings on related work. An evaluation of the
developed prototype was done. Results of the evaluation showed that it is
possible to develop effective and useful visualisations for mobile platforms.
The results also indicated that users were able to report a level of satisfaction
as they interacted with the prototype and attributed this to the ease of use
of the prototype and simple layout.
