Lessons learned from a novel communication interaction in authentic use over an eight-week evaluation period by twenty participants in two work-social groups. These lessons include verification of other studies showing the lack of explicit user setting of situation data, benefits of iterative development of the interaction to incorporate context, and future directions to find the "point of mutual agreement" between caller and callee.
The authors have presented the evolution of iCAM system and a user study, but the contributions of the project deserve to be explored more deeply. The summary of the evolution of the iCam system is thorough, but does not adequately motivate the human needs nor distinguish the system from existing enhanced telephony systems, with its periodic and automatic update of location. In the user study, the presentation of questionnaire results is comprehensive and bolstered by interview data, but this structure depends upon the reader to collate the points across questionnaire responses. The experiences of this study may provide more meaning if they were grouped according to human usage, substantiating with corresponding questionnaire and interview data. This study has potential to delve into:
1. Mediation of purpose driven communication initiation
2. Gathering situation awareness of other group members
3. When human mediation of desired communication channel differs from rules
4. Adopting the interaction into existing everyday activities
5. Differing needs for location granularity
6. Evolving privacy concerns
For each of these human experiences, there was support across several responses, and when taken together yield a richer story of human use. The notion of location granularity was significant in several actions, but differed when one member of the group was remotely located and did not have a shared understanding of how spaces were utilized. The implicit meaning of location information varied within the group and across tasks. Another concern is the privacy was closely related to the depth of personal relationship, but did the number of uses of Top Page for location awareness enhance the feeling of closeness and thus affect the "changed notion of location disclosure"? The investigation of these other mutual agreement points for caller and callee will contribute to the design space of pervasive communication.
Introduction includes "Because the modes of communication have become so varied, it is difficult to make appropriate use of these various media and addresses …", but it is not clear how iCam solves the problem of situational use, through location and sometimes schedules. If a scenario where location determines the communication mode, then iCam is better situated in the human experience.
When CAMS "redirects each incoming message dynamically", it is not obvious why this is a problem. Is it that the callee desires to over-ride the redirect to email, with a conversation, but is unable?
The project overview will be clearer when the grammatical errors are edited.
Comments for EIC and AEICs only:
If accepted, this paper needs careful reviewing of its user study results and discussion for clarity of project results. The entire paper will benefit from a careful editing for grammar and spelling errors.
