【 摘 要 】

Web 2.0 services such as Twitter or Facebook are all around us and with us every day through the introduction of smartphones and tablets alike. The ever increasing feature set, faster ways to connect to the Internet and larger screen real estate that mobile devices are equipped with, allow Web 2.0 services to flood users with more and more information. This avalanche of information becomes unmanageable in its complexity and quantity and turns into information overload.To counteract the users’ feeling of information overload a new 3D personalised augmented reality user space was designed and implemented. It employes the techniques such as augmented reality and information filtering in a 3D environment to reduce information complexity and information overload. This new application was developed for a tablet computer and focuses on the humans’ natural abilities of spatial awareness. To test the underlying assumptions a set of experiments was designed and user trials are conducted to investigate the usability and navigability as well as the perceived information load.Following the data gathering phase of the experiment, it was statistically analysed to compare two different approaches. For this purpose a 2D and a 3D version of the same application had been developed. Comparing the results of the user study, no statistically relevant difference in usability could be established. The results suggest that the users’ perception of information overload did not get better in the new 3D interface, and it did not get worse either.The results and observations analyses following the user experiment strongly suggest that information overload should be considered during the application development process of Web 2.0 applications. This research shows there is no usability loss when using the 3D interface over the 2D interface. Further research and development into the areas of spatial knowledge and awareness in 3D information systems may reduce the information load felt by users of current information rich systems.
