  • Abstract: The research presented below examines how novel pervasive technology can support intra-family communication, supporting existing practices and complimenting them by addressing communication needs currently unmet by current communication media, like mobile phones, social networking systems, etc. Specifically the investigation focused on busy families, understood here to be families with two working parents and at least one child sharing the same roof. The class of technologies we considered are awareness systems, defined as communication systems that support individuals to maintain, with low effort, a peripheral awareness of each other’s activities and whereabouts. This research combined a variety of research methods including interviews, web surveys, experience sampling, field testing of functional prototypes of mobile awareness systems. It also involved the development of several applications, which were either seen as research tools in support of the methods applied or as prototypes of awareness systems that embody some of the envisioned characteristics of this emerging class of technologies. The contribution of this research is along two main dimensions. First in identifying intra-family communication needs that would drive the adoption of awareness systems and second in providing directions for the design of such systems.

    Abstract: The Experience Sampling and Reconstruction (ESRM) method is a research method suitable for user studies conducted in situ that are needed for the design and evaluation of ambient intelligence technologies. ESRM is a diary method supported by a distributed application, Reconexp, which runs on a mobile device and a website, enabling us to survey user attitudes, experiences, and requirements in field studies. ESRM combines aspects of the Experience Sampling Method and the Day Reconstruction Method aiming to reduce data loss, improve data quality and reduce burden put upon participants. We present a case study of using this method in the context of a study of communication needs of working parents with young children. Requirements for future developments of the tool and the method are discussed.

    Abstract: Does pervasive technology have a role to play in supporting the communication of busy couples? Especially when they are already living together and already have a high degree of awareness of each other’s rhythms of daily life, their whereabouts and needs? A two weeks long field study of an awareness system allowed eight working couples to automatically exchange place, activity and calendar information as well as messages and photos. Data analysis provides both qualitative and quantitative evidence which suggest strongly that such a system can provide support for availability, coordination, reassurance and affection for this group. Findings which inform the design of such systems are: the need of transitions in places instead of location information to support coordination, the two tracks of daily communication of busy parents (reassurance and emergency) and usability barriers in current mobile applications which prevent this group in engaging in photo sharing. The contexts and unexpected uses which participants found in the system are described in detail.

    Abstract: This work examines how Awareness Systems, a class of technologies that support sustained and effortless communication between individuals and groups, can support family communication. Going beyond the evaluation of specific design concepts, this paper reports on three studies that aimed to answer the following research questions: (a) Do families want to be aware of each other through the day? Or, would they perhaps rather not know more about each other’s activities and whereabouts than they already do? (b) If they do wish to have some awareness, what should they be aware of? The research involved in-depth interviews with 20 participants, a field trial of an awareness system connecting five “busy” parents with their children and a survey of 69 participants conducted over the web. Triangulation of the results of the three studies leads to the following conclusions: (a) Some busy parents want to automatically exchange awareness information during the day while others do not. (b) Availability of partner for coordinating family activities, daily activities in new family situations, activity, and location information of dependent children are salient awareness information needs for this group. (c) Awareness information needs to vary with contexts, suggesting the need for flexible mechanisms to manage the sharing of such information.
