Understanding Interaction with ML through a Thematic Analysis Coding Assistant

Interactive Machine Learning (ML) enables users, including non-experts in ML, to iteratively train and improve ML models. However, limited research has been reported on how non-experts interact with these systems. Focusing on thematic analysis as a practical application, we report on a user study where 20 participants…

SolarClub: Supporting Renewable Energy Communities through an Interactive Coordination System

Energy communities are a key focus for governments around the world in support of more sustainable energy practices. However, interactive systems for supporting energy communities to coordinate around renewable energy resources are still lacking. We present SolarClub, a demand-shifting visualization system that suppor…

Chatbots as Advisers: the Effects of Response Variability and Reply Suggestion Buttons

As chatbots gain popularity across a variety of applications, from investment to health, they employ an increasing number of features that can influence the perception of the system. Since chatbots often provide advice or guidance, we ask: do these aspects affect the user’s decision to follow their advice? We focus on…

Speech-Augmented Cone-of-Vision for Exploratory Data Analysis

Mutual awareness of visual attention is crucial for successful collaboration. Previous research has explored various ways to represent visual attention, such as field-of-view visualizations and cursor visualizations based on eye-tracking, but these methods have limitations. Verbal communication is often utilized as a…

Cone of Vision as a Behavioural Cue for VR Collaboration

Mutual awareness of visual attention is essential for collaborative work. In the field of collaborative virtual environments (CVE), it has been proposed to use Field-of-View (FoV) frustum visualisations as a cue to support mutual awareness during collaboration. Recent studies on FoV frustum visualisations focus on asy…

Visions, Values, and Videos: Revisiting Envisionings in Service of UbiComp Design for the Home

UbiComp has been envisioned to bring about a future dominated by calm computing technologies making our everyday lives ever more convenient. Yet the same vision has also attracted criticism for encouraging a solitary and passive lifestyle. The aim of this paper is to explore and elaborate these tensions further by exa…

Evaluating the Effect of Feedback from Different Computer Vision Processing Stages: A Comparative Lab Study

Computer vision and pattern recognition are increasingly being employed by smartphone and tablet applications targeted at lay-users. An open design challenge is to make such systems intelligible without requiring users to become technical experts. This paper reports a lab study examining the role of visual feedback. O…

Understanding the Shared Experience of Runners and Spectators in Long-Distance Running Events

Increasingly popular, long-distance running events (LDRE) attract not just runners but an exponentially increasing number of spectators. Due to the long duration and broad geographic spread of such events, interactions between them are limited to brief moments when runners (R) pass by their supporting spectators (S).…

Tracking the Consumption of Home Essentials

Predictions of people's behaviour increasingly drive interactions with a new generation of IoT services designed to support everyday life in the home, from shopping to heating. Based on the premise that such automation is difficult due to the contingent nature of people's practices, in this work we explore the nature…

Learning from the Veg Box: Designing Unpredictability in Agency Delegation

The Internet of Things (IoT) promises to enable applications that foster a more efficient, sustainable, and healthy way of life. If end-users are to take full advantage of these developments we foresee the need for future IoT systems and services to include an element of autonomy and support the delegation of agency t…
