Together with 11 lower-income households, we explored how assumptions embedded in domestic energy interfaces match their needs, expectations, and everyday practices around domestic energy use and comfort. Catalyzed by cultural probes, residents (1) shared the diverse strategies and know-how involved in making themselves comfortable, (2) offered arg...

Music can have a positive effect on the quality of life of people with dementia (PwD). Unfortunately, PwD have limited access to music due to difficulties in product use and loss of initiative. Most studies on designing for PwD focus on improving the interaction design and do not consider the loss of initiative PwD experience. We propose that produ...

When practitioners are in the midst of their busy day-to-day work—such as teachers facilitating learners in the classroom or nurses caring for patients in the hospital—they face complex social or material environments and intensive, intertwined activities. Yet unprecedentedly, these practitioners also need to incorporate technologies, as increasing...

This article reports the results of an experiment (N = 10) that employs continuous auditory feedback to influence participants’ routing choices while walking between two points by sonifying their interactions with invisible obstacles. A relative distance parameter, proximity, is defined and mapped simultaneously to perceived loudness and amplitude...

Designing for people with dementia requires a tailored approach that addresses the specific complexities related to dementia. Design principles can provide guidance for designing in this complex context. Work in this field discusses recommendations, guidelines, or principles to design for dementia. However, this information is scattered and a clear...

Data-enabled design (DED) is a promising new methodology for designing with users from within their own context in an iterative and hands-on fashion. However, the agile and flexible qualities of the methodology do not directly translate to every context. In this article, we reflect on the design process of an intelligent ecosystem, called ORBIT, an...

Closing the loop of products and materials in Product Service Systems (PSS) can be approached by designers in several ways. One promising strategy is to invoke a greater sense of ownership of the products and materials that are used within a PSS. To develop and evaluate a design tool in the context of PSS, our case study focused on a bicycle sharin...

People with dementia and their caregivers aging in place have expressed the need for social, emotional, and recreational interventions at home.

The progressive nature of dementia influences a person’s physical and cognitive functioning. Research has shown that offering multisensory interactions for people with dementia can improve their beh...

Music and familiar everyday sounds can be meaningful for people with dementia by providing benefits such as evoking memories and emotions or prompting social interactions with caregivers or relatives. Motivated by this potential, researchers and designers are investigating how to leverage these beneficial effects of sound in care environments throu...

External human-machine interfaces (eHMIs) support automated vehicles (AVs) in interacting with vulnerable road users such as pedestrians. While related work investigated various eHMIs concepts, these concepts communicate their message in one go at a single point in time. There are no empirical insights yet whether distance-dependent multi-step info...

Motivated by the successes of music in dementia, researchers and designers in HCI are exploring the potential benefits of non-musical sounds from everyday life for people with dementia. Research in the field of building acoustics and psychology is suggesting that re-presenting everyday sounds as soundscapes in the care space can influence emotional...

People with dementia (PwD) risk a deterioration in quality of life (QoL) as the dementia progresses. A growing number of studies show that music can increase QoL. Unfortunately, loss of initiative and problems during product-use hinder access to music. In this paper we first depict a gap in knowledge on the needs of PwD in relation to listening to...

The representation of sounds derived from everyday life can be beneficial for people with dementia by evoking memories and emotional responses. Despite this potential, integrating sound and sound-based interventions in care facilities has not received much research attention. In this paper, we present the findings from a field study that explored t...

In the past two years, an emerging body of HCI work has been focused on classroom proxemics - how teachers divide time and attention over students in the different regions of the classroom. Tracking and visualizing this implicit yet relevant dimension of teaching can benefit both research and teacher professionalization. Prior work has proved the v...

Recently, the HCI community has seen increased interest in the design of teaching augmentation (TA): tools that extend and complement teachers' pedagogical abilities during ongoing classroom activities. Examples of TA systems are emerging across multiple disciplines, taking various forms: e.g., ambient displays, wearables, or learning analytics das...

Although empathy is an essential aspect of co-design, the design community lacks a systematic overview of the key dimensions and elements that foster empathy in design. This paper introduces an empathic formation compass, based on a comparison of existing relevant frameworks. Empathic formation is defined here as the formative process of becoming a...

Most systems that we use in everyday life are shared—because multiple people can interact or because an interaction by one person can affect other people. However, everyday Internet of Things systems are often designed for individual use. Prior research on collaboration technologies (Computer Supported Collaborative Work) has shown that to coordina...

This paper explores how we can design personalised auditory experiences for people with dementia (PwD). We introduce a new product design called the SoundscapePillow. The SoundscapePillow is a long tubular shape changing pillow that enables personalised auditory experiences for PwD by listening to (nature) soundscapes. The built-in sound system pro...

The inclusion of IoT in office lighting allows people to have personal lighting control at their workplace. To design lighting control interfaces that fit people’s everyday living, we need a better understanding of how people experience lighting interaction in the real world. Still, lighting control is often explored in controlled settings. This wo...

Reflecting on their performance during classroom-teaching is an important competence for teachers. Such reflection-in-action (RiA) enables them to optimize teaching on the spot. But RiA is also challenging, demanding extra thinking in teachers' already intensive routines. Little is known on how HCI systems can facilitate teachers' RiA during classr...

Can interactions between automated vehicles and pedestrians be evaluated in a quantifiable and standardized way? In order to answer this, we designed an input device in the form of a continuous slider that enables pedestrians to indicate their willingness to cross a road and their feeling of safety in real time in response to an approaching vehicle...

Reflection-in-action (RiA) refers to teachers' reflections on their teaching performance during busy classroom routines. RiA is a demanding competence for teachers, but little has been known about how HCI systems could support teachers' RiA during their busy and intensive teaching. To bridge this gap, we design and evaluate an ambient information s...

The number of systems in commercially available vehicles that assist or automate driving tasks is rapidly increasing. At least for the next decade, using such systems remains up to the discretion of the user. In this paper, different reasons why drivers may disengage the autopilot are investigated. This was done through a simulator study in which t...

This study aims at validating the transferability of the Empathic Handover approach, which we originally developed for the co-design process of a dementia simulator. We argue that empathy in design is operationalised using five factors: emotional interest, sensitivity, self-awareness, personal experience, and mixed perspectives. This heuristic prov...

The aim of this study was to investigate the predictive value of the Multidimensional Driving Style Inventory (MDSI) for driving behaviour in a driving simulator, in terms of speeding, braking, steering, lateral positioning and maintaining distance to a preceding vehicle. Eighty-eight participants, mainly from the Netherlands and Belgium, filled in...

Interfaces are commonly designed from the perspective of individual users, even though most of the systems we use in everyday life are in fact shared. We argue that more attention is needed for system sharing, especially because interfaces are known to influence coordination of shared use. In this work, we aim to deepen the understanding of this re...

As necessary for creating a learner-centered environment, nowadays teachers are expected to be more mindful about their proximity distribution: how to spend time in different locations of the classroom with individual learners. However feedback on this is only given to teachers by experts after classroom observation. In this paper we present the de...

This dataset contains of results of a study that aimed add investigating the relationship between interface characteristics of lighting interfaces and eventual light use and the lighting experience.

Reflection in and on everyday life can provide self-insight, increase gratitude and have a positive effect on well-being. To integrate reflection in everyday life, media technologies can provide support. In this paper, we explore how both media creation & use in different modalities can support reflection. We present the ongoing work of designing a...

It is difficult to inform design with experiences from people with dementia. When it comes to involving this vulnerable user group and connecting multidisciplinary design teams, current empathic co-design methods and tools are scarce, seem fragmented and lack a coherent and structured approach. In response, we provide guidance to design teams by pr...

Cherished utilitarian objects can provide comfort and pleasure through their associations to our personal past and the time and energy we have invested in and with them. In this paper, we present a specific type of object relationship, which we call the companion. They are mundane objects that accrued meaning over time, and evoke tiny pleasures whe...

Broad adoption of intelligent systems is a condition for achieving the aims of these systems such as increasing safety and efficiency. This requires taking into consideration that each driver has his or her own needs, interests and motivations while driving. Persuasive strategies that are intended to increase the adoption of intelligent systems may...

There is an increasing interest in HCI in designing to support reflection in users. In this paper, we specifically focus on everyday life reflection, covering and connecting a broad range of topics from someone's life rather than focusing on a very specific aspect. Although many systems aim to support reflection, few are based on an overview of how...

In this work, we investigate how to design multi-user interfaces for shared environments by implementing social translucence: Visibility of socially relevant information, awareness of other people, and accountability for actions. By designing and analysing 126 multi-user lighting interface concepts, we define four strategies to implement socially r...

Interfaces of interactive systems for domestic use are usually designed for individual interactions although these interactions influence multiple users. In order to prevent conflicts and unforeseen influences on others we propose to leverage the human ability to take each other into consideration in the interaction. A promising approach for this i...

In the emerging design landscape, knowledge integration and collaboration with external partners are being valued in the design process due to the increasing scale and complexity of the design problems.

When children play games like tag or jump rope, they often combine generally accepted predefined rules with their own invented and negotiated rules. These rules also occur in play with interactive play objects. In this field, we research children’s interactions with open-ended play designs that offer interaction opportunities to which children can...

Interactive technology is becoming more strongly integrated in innovative play solutions. As play is often a social experience, understanding the dynamic social context in which such play takes place is an essential step in designing new interactive play environments. In this paper, we explore the notion of social interaction in the context of open...

New technologies enable designers to create advanced visual representations of concepts (e.g., animations, renderings) early in the design process. However, it is not clear whether and how the properties of such concept representations affect the users’ understanding of the concept and the nature of the feedback they provide. To explore this we con...

In everyday life, we are able to perceive information and perform physical actions in the background or periphery of attention. Inspired by this observation, several researchers have studied interactive systems that display digital information in the periphery of attention. To broaden the scope of this research direction, a few recent studies have...

In this paper we present the "Co-constructing Stories" method, aiming to elicit feedback from end-users on novel design concepts in the early phases of the design process. In sessions of less than an hour, participants are prompted by a storyboard depicting the current situation to recollect relevant real-life experiences for sensitization. Next, p...

Many actions in the physical world take place in the background or periphery of people's attention. However interactions with computing technologies usually require focused attention. This paper explores the concept of peripheral interaction: physical interaction with technology that takes place outside the focus of attention. A peripheral interact...

For a long time people have collected mementos; items kept as reminder of a person, place or event. Practices of memento creation are constantly changing; for instance through the accessibility of digital photography. Still, we most often create mementos of special occasions such as weddings or holidays. However, besides these milestones, we cheris...
