The Hans Christian Andersen (HCA) system is an example of a new generation of embodied conversational characters which are aimed to faithfully represent a familiar historical individual and carry out human-style conversation as that individual would have done had he or she lived today. A first prototype of fairytale author HCA was tested with representative users in January 2004. This paper reports on the user test of the second prototype which was done in February 2005, focusing on the structured user interview results. 1.

in resurrecting a familiar historical character and make this individual carry out human-style natural interactive conversation. We tested the first research prototype of fairytale author HCA with representative users in January 2004 and nearreplicated the test setup when testing the second prototype in February 2005. This paper compares the results of the structured user interviews made right after each of the two tests. 1.

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. Index Terms — experienced user performance, novel user performance, speech recognition, usability. I.
