Physical inactivity has increased significantly over the past years, andthe advancement of technology has contributed to it. Paradoxically,domestic IoT shapes human behavior through human interaction. Aseveryday objects become a part of the Internet of Things (IoT), thisthesis aims to investigate how the IoT devices and everyday objects cancollaborate with humans to address growing physical inactivity.Using a speculative and critical design approach, design proposals in theform of physical and video prototypes are constructed and discussed in aseries of workshops. Participation in the workshops moves theparticipants from being passive consumers of technology to citizens thatactively debate and design their own future.The outcomes of the workshops are themes that critically address theimplications of domesticating technology and its future roles andfunctions. Also, a set of characteristics is outlined to illustrate desirable,undesirable, and preferred characteristics of networked technologies thatmay encourage physical activity.
