Mobile and wearable computers present input/output prob-lems due to limited screen space and interaction techniques. When mobile, users typically focus their visual attention on navigating their environment - making visually demanding interface designs hard to operate. This paper presents two multimodal interaction techniques designed to overcome these(More)
Desktop user interface design originates from the fact that users are stationary and can devote all of their visual resource to the application with which they are interacting. In contrast, users of mobile and wearable devices are typically in motion whilst using their device which means that they cannot devote all or any of their visual resource to(More)
Data quality is a difficult notion to define precisely, and different communities have different views and understandings of the subject. This causes confusion, a lack of harmonization of data across communities and omission of vital quality information. For some existing data infrastructures, data quality standards cannot address the problem adequately and(More)
When designing interaction techniques for mobile devices we must ensure users are able to safely navigate through their physical environment while interacting with their mobile device. Non-speech audio has proven effective at improving interaction on mobile devices by allowing users to maintain visual focus on environmental navigation while presenting(More)
abstract The phenomena a usability test in the field reveals are different from those uncovered in a classical usability test conducted in a laboratory setting. Comparison studies show that these findings are more related to the user experience and user behaviour than usability and user interaction with the device. Testing in the field is a necessary part(More)
ion of user interfaces adds flexibility when generating user interfaces. It provides a single and comprehensive description of the user interface. It is a rich layer of information that describes a user’s interaction with the computer. Such abstraction is formalized by using an abstract user interface definition language (Stottner, 2001) or task models(More)
For a very large number of adults, tasks such as reading. understanding, and using everyday items are a challenge. Although many community-based organizations offer resources and support for adults with limited literacy skills. current programs have difficulty reaching and retaining those that would benefit most. In this paper we present the findings of an(More)
