Behind the Lens: A Visual Exploration of Epistemological Commitments in HCI Research on the Home

   In this pictorial, we propose an alternative approach to investigating human-computer interaction (HCI) researchers’ epistemological commitments in research on the home. While researchers’ commitments can be discussed through textual aspects of their research, in this pictorial we conduct a pattern analysis of visual elements as a productive way to further inquire into such kinds of commitments. By analyzing visual elements from 121 works in HCI research on the home, we identify seven types of observers, which can be associated with epistemological commitments in research. We also propose two new complementary observers: the absent observer and the protagonist observer

Investigating Genres and Perspectives in HCI Research on the Home

The home and domestic experiences have been studied from multiple points of view and disciplines, with an array of methodologies in the past twenty-five years in HCI. Given the attention to the home and the volume of research, what further areas of research might there be? Based on a critical analysis of 121 works on the topic, we present seven genres of domestic technology research in HCI: social routines in the home, ongoing domestic practices, the home as a testing ground, smart homes, contested values of a home, the home as a site for interpretation, and speculative visions of the home. We articulate dominant research perspectives in HCI, and we offer two complementary perspectives about how to investigate the domestic experience in future research: the material perspective and the first person perspective

Collaborative Modeling of Business Processes on Co-Located TableTop Systems

Most current Business Process Management Systems (BPMS) refer to single users, working at a desktop PC individually. But especially, during the creation of process models, domain and modeling experts work together. Therefore, a collaborative BPMS offers possibilities to work in a team environment. The advantages of collaborative process modelling are improved quality and accuracy of process models. Thus, the user’s workload is reduced and the users learn from each other. This thesis presents Process-Touch, which is a collaborative BPMS, using a tabletop and additional tablets or smartphones to create process models collaboratively. Process-Touch offers an easy to use Natural User Interface (NUI), sketch-based input and the possibility to work with tablets or smartphones as a private interaction device. Users can create and edit parts of the process model on their tablets and smartphones and merge them on the tabletop using a tap gesture to transfer the process model from the mobile device to the tabletop. This thesis contributes a system for collaborative BPMS, general concepts and requirements and a prototypical implementation. Moreover, the concept is evaluated by experimental research, using the prototypical implementation. Hence, improvements of the gesture-set, interaction design and implementation are identified and discussed
