“No powers, man!”: A student perspective on designing university smart building interactions

Smart buildings offer an opportunity for better performance and enhanced experience by contextualising services and interactions to the needs and practices of occupants. Yet, this vision is limited by established approaches to building management, delivered top-down through professional facilities management teams, opening up an interaction-gap between occupants and the spaces they inhabit. To address the challenge of how smart buildings might be more inclusively managed, we present the results of a qualitative study with student occupants of a smart building, with design workshops including building walks and speculative futuring. We develop new understandings of how student occupants conceptualise and evaluate spaces as they experience them, and of how building management practices might evolve with new sociotechnical systems that better leverage occupant agency. Our findings point to important directions for HCI research in this nascent area, including the need for HBI (Human-Building Interaction) design to challenge entrenched roles in building management

People and a virtual doctor’s visit: learning about multiple facets of acceptance in a telemedical scenario

In this paper we report on a study exploring multiple aspects of a virtual doctor’s visit as a commonly used example for telemedical services. We compare the conventional doctor’s visit with the virtual visit to identify user requirements and needs for the acceptance of such a scenario. In our survey we retrieved data from a total of 93 users between 16 and 67 years. The results of this study describe differences (and similarities) of criteria for choosing a doctor, basic requirements to accept a virtual doctor’s visit, and people’s opinions on common pro and contra arguments on this scenario. We analyzed the data for potential influences from various user characteristics, such as age, gender, social behavior, or technical competence. Interestingly, most of the reported concerns are not influenced by gender or age, while participants’ technical self-confidence is related with various acceptance aspects

Integrating the Smart Home into the Digital Calendar

With the growing adoption of smart home technologies, inhabitants are faced with the challenge of making sense of the data that their homes can collect to configure automated behaviors that benefit their routines. Current commercial smart home interfaces usually provide information on individual devices instead of a more comprehensive overview of a home’s behavior. To reduce the complexity of smart home data and integrate it better into inhabitants’ lives, we turned to the familiar metaphor of a calendar and developed our smart home interface Casalendar. In order to investigate the concept and evaluate our goals to facilitate the understanding of smart home data, we created a prototype that we installed in two commercial smart homes for a month. The results we present in this paper are based on our analysis of user data from questionnaires, semi-structured interviews, participant-driven audio and screenshot feedback as well as logged interactions with our system. Our findings exposed advantages and disadvantages of this metaphor, emerging usage patterns, privacy concerns and challenges for information visualization. We further report on implications for design and open challenges we revealed through this work

From Today's Augmented Houses to Tomorrow's Smart Homes: New Directions for Home Automation Research

A considerable amount of research has been carried out towards making long-standing smart home visions technically feasible. The technologically augmented homes made possible by this work are starting to become reality, but thus far living in and interacting with such homes has introduced significant complexity while offering limited benefit. As these technologies are increasingly adopted, the knowledge we gain from their use suggests a need to revisit the opportunities and challenges they pose. Synthesizing a broad body of research on smart homes with observations of industry and experiences from our own empirical work, we provide a discussion of ongoing and emerging challenges, namely challenges for meaningful technologies, complex domestic spaces, and human-home collaboration. Within each of these three challenges we discuss our visions for future smart homes and identify promising directions for the field
