192 7. Ongoing and future work Anais do IHC’2001 - IV Workshop sobre Fatores Humanos em Sistemas Computacionais As our digital library work becomes more widely used both within our community and among external users, we are continually receiving feedback, adapting our software development plans and finding new application areas. We are currently working on a better integration of personal and group spaces. In upcoming versions of MiBiblio and MiStudio, “doors” will appear in rooms representing personal spaces for each of the available group spaces. Users will be able to exit a personal space to enter a specific group space by traversing the appropriate door. We have defined various formal tests of the prototypes, particularly in the areas of usability, robustness and scalability. We are currently in the process of applying these tests. One feature of EGA that has not been experimented with more fully is the capability of group participants to move their individual images around the group space to create user clusters that reflect positions in a discussion. We intend to encourage users to take advantage of this facility and report results in the near future. We also plan to explore the definition of implicit group spaces to supplement EGA’s current functionality. Our own previous work in a related project [Sánchez et al. 1998] can be adapted to our ongoing digital libraries initiative. In this area, we are currently exploring the use of videoconferencing as a way to widen the relatively limited communication channel provided by our text-based conversational component. Finally, we are working on the definition of an appropriate upper limit for the number of participants in group spaces, as in some cases problems have been observed as the number of users grows. From our results thus far, we believe personal and group spaces are a promising approach to the integration of highly distributed, heterogeneous information spaces. Our design and prototypical implementations show that our approach may effectively help users in coping with the size, complexity and dynamism of digital libraries.
