“…This technology can contribute in improving the efficiency and communication of governments, facilitate economic development and reduce cost. It also contributes to meet citizens' expectations for service delivery by facilitating administrative procedures (Alsaghier, Ford, Nguyen, & Hexel, 2009;Rigas, Memery, & Yu, 2001).…”

Interfaces for e-government applications are becoming essential for the modern life. E-government uses web-based interfaces to deliver effective, efficient and convenient services to citizens, business and government. However, one of the main obstacles (or barriers) of using such applications is the lack of the user trust and usability. These issues are often neglected in the interfaces of e-government application. This paper describes an empirical comparative study that investigated the use of multimodal metaphors to enhance the usability and increase the user trust. Specific designs of multimodal metaphors were investigated to communicate information using a specially developed e-government interface platform. These designs involved facially animated expressive avatars and auditory stimuli in addition to the typical visual metaphors often used. An experiment was carried out with 30 users to explore and compare the usability and user performance. These results provided a set of empirically derived innovative guidelines for the design and use of these metaphors to generate more usable e-government interfaces. For example, when designing avatars as animated virtual messages or live mail in e-government interfaces, specific facial expression should be incorporated due to its positive influence in enhancing users‘ attitude towards the communication process.

“…Many studies recommend using earcons [31,32,37] and auditory icons [17][18][19]42] as auditory solutions to enhance usability of graphical metaphors. However, in order for these interaction metaphors to be properly perceived and correctly mapped to the meanings they are designed to convey, the user is required to maintain a high level of concentration and try to develop a correct perceptual context [35,36].…”

Developers of visual Interface Design Environments (IDEs), like Microsoft Visual Studio and Java NetBeans, are competing in producing pretty crowded graphical interfaces in order to facilitate completion of interface-design tasks. Previous studies have shown that such interfaces cause the user to experience information overload as well as they create a fertile environment for usability problems. In this paper, we empirically investigate speech as an input and output means for solving usability problems with GUI interaction metaphors and enhancing usability of visual IDEs. The empirical investigation aimed at measuring usability of two experimental ID toolkits: typical visual-only (TVOID) and multimodal (MMID) in terms of efficiency, effectiveness and satisfaction. Usability of these two environments was tested twice, over two experimental phases, by four independent groups of users. The first experimental phase was for measuring usability by novel users in order to explore how learnable each of the two experimental toolkits would be. The second phase aimed at measuring usability by well-trained users to study experienced user performance when using a speech recognition ID.
