Designing assisted living technologies 'in the wild' : preliminary experiences with cultural probe methodology

Background There is growing interest in assisted living technologies to support independence at home. Such technologies should ideally be designed ‘in the wild’ i.e. taking account of how real people live in real homes and communities. The ATHENE (Assistive Technologies for Healthy Living in Elders: Needs Assessment by Ethnography) project seeks to illuminate the living needs of older people and facilitate the co-production with older people of technologies and services. This paper describes the development of a cultural probe tool produced as part of the ATHENE project and how it was used to support home visit interviews with elders with a range of ethnic and social backgrounds, family circumstances, health conditions and assisted living needs. Method Thirty one people aged 60 to 98 were visited in their homes on three occasions. Following an initial interview, participants were given a set of cultural probe materials, including a digital camera and the ‘Home and Life Scrapbook’ to complete in their own time for one week. Activities within the Home and Life Scrapbook included maps (indicating their relationships to people, places and objects), lists (e.g. likes, dislikes, things they were concerned about, things they were comfortable with), wishes (things they wanted to change or improve), body outline (indicating symptoms or impairments), home plan (room layouts of their homes to indicate spaces and objects used) and a diary. After one week, the researcher and participant reviewed any digital photos taken and the content of the Home and Life Scrapbook as part of the home visit interview. Findings The cultural probe facilitated collection of visual, narrative and material data by older people, and appeared to generate high levels of engagement from some participants. However, others used the probe minimally or not at all for various reasons including limited literacy, physical problems (e.g. holding a pen), lack of time or energy, limited emotional or psychological resources, life events, and acute illness. Discussions between researchers and participants about the materials collected (and sometimes about what had prevented them completing the tasks) helped elicit further information relevant to assisted living technology design. The probe materials were particularly helpful when having conversations with non-English speaking participants through an interpreter. Conclusions Cultural probe methods can help build a rich picture of the lives and experiences of older people to facilitate the co-production of assisted living technologies. But their application may be constrained by the participant’s physical, mental and emotional capacity. They are most effective when used as a tool to facilitate communication and development of a deeper understanding of older people’s needs

Human-Centred Smart Buildings: Reframing Smartness Through the Lens of Human-Building Interaction

PhD ThesisSmart buildings backed by data and algorithms promise reduced energy use and increased value for businesses and occupants. Yet, this has typically been considered from an engineering and systems perspective. Given increasing integration of sensing and ubiquitous computing technologies in modern built environments, a growing HumanComputer Interaction (HCI) and Human-Building Interaction (HBI) community has begun to advocate for the human-centred design of building technologies. This dissertation argues that there is a need for an inclusive, socially just and sustainable HBI agenda, to enable smarter buildings and facilities management. Deconstructing ‘smart’ rhetoric within HCI/HBI discourse and highlighting the values and ethics underpinning it, I argue that existing approaches to ‘smartness’ privilege automation and efficiency over the needs of human occupants. I undertake a qualitative inquiry into the roles of data and digital technologies in human-centred smart buildings through three case studies: i) How retrofitted environment sensors facilitate smarter energy auditing practices. I contribute a methodology for using sensor toolkits in auditing, technical design of the BuildAX sensing platform, and insights into sensoraugmented audits and how future standards might support these. ii) How data and digital technologies foster collective experiences of thermal comfort for office workers. I contribute a data elicitation interview method, design of the ThermoKiosk experience survey system, and considerations for integrating office tensions into workplace comfort management. iii) How HBI can support agency and participation in the everyday management and adaptation of a contemporary smart building. I contribute a ‘building walks’ method to elicit conversations on the future of building technologies, new understandings of how student occupants conceptualise and evaluate spaces, and how buildings of the future might better enable occupant agency. Through these, I contribute a re-framing of smartness to be more human-centred, including concerns for collaboration, inclusion, and human decision-making which does not consider occupants a ‘problem’ to be solved. The results of the case studies are synthesised into a set of six principles for the design of technology within human-centred smart buildings, re-grounding the field of HBI in the philosophy of environmental and social justice

From Robot-Assisted Intervention to New Generation of Autism Screening: an Engineering Implementation Beyond the Technical Approach

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects people from birth, whose symptoms are found in the early developmental period. The ASD diagnosis is usually performed through several sessions of behavioral observation, exhaustive screening, and manual coding behavior. The early detection of ASD signs in naturalistic behavioral observation may be improved through Social Assistive Robotics (SAR) and technological-based tools for an automated behavior assessment. Robot-assisted tools using Child-Robot Interaction (CRI) theories have been of interest in intervention for children with Autism Spectrum Disorder (CwASD), elucidating faster and more significant gains from the diagnosis and therapeutic intervention when compared with classical methods. Additionally, using computer vision to analyze the childs behaviors and automated video coding to summarize the responses would help clinicians to reduce the delay of ASD diagnosis. Despite the increment of researches related to SAR, achieving a plausible Robot-Assisted Diagnosis (RAD) for CwASD remains a considerable challenge to the clinical and robotics community. The work of specialists regarding ASD diagnosis is hard and labor-intensive, as the conditions manifestations are inherently heterogeneous and make the process more difficult. In addition, the aforementioned complexity may be the main reason for the slow progress in the development of SAR with diagnostic purpose. Also, there still is a lack of guidelines on how to select the appropriate robotic features, such as appearance, morphology, autonomy level, and how to design and implement the robots role in the CRI. Thus, this Ph.D. Thesis provides a comprehensive Robot-Assisted intervention for CwASD to assess autism risk factors for an autism diagnostic purpose. More specifically, two studies were conducted to analyze and validate the system performance. Through statistical data analysis, different behavior pattern of the CwASD group were identified, which suggest that these patterns can be used to detect autism risk factors through robot-based interventions. To increase the scope of this research, a theoretical conceptualization of the pervasive version of the multimodal environment was described as well as a participatory design methodology was designed and implemented on the Colombian autism community, providing, a set of guidelines regarding the design of a social robot-device suitable to be applied for robot-assisted intervention for CwASD

Understanding wrist splint user needs and personalisation through codesign

Wrist splints are a common treatment for rheumatoid arthritis, however their effectiveness is compromised by patients not wearing splints as often as prescribed. Previous research has identified a number of reasons for non-compliance, but typically lacks insights that could lead to improved splint design.This thesis investigates the motivators for patients to wear and not wear their wrist splints and, the impact of personalisation of splint appearance on patient wear. The work is based on the premise that digital design and manufacturing processes, such as Computer-Aided Design (CAD) and 3D Printing, can produce bespoke splints on demand.The research begins with a literature review across the core areas of: splinting, additive manufacture, product appearance and personalisation. This literature review identifies gaps in knowledge from which research questions are established for the work.The research employs a qualitative, generative design research approach and, follows a codesign framework employing telling, making and enacting tools. The thesis is made up of three studies. The first study is a sensitisation study and uses design probes to prepare the participants for the research and begin exploring the problem space. The second is a comprehensive study into participants splint wear behaviour and uses context mapping and scenario picture card tools to investigate the motivators for participants to wear and not wear wrist splints, along with positive and negative outcomes or wearing/not wearing splints. The final study uses a personalisation toolkit to elicit patient needs for a future wrist splint design and investigate self-reported expectations regarding compliance of patients who used the toolkit.The research finds that patient compliance is affected by practical and aesthetic limitations of current splints. It identifies 4 motivating factors to wear a splint and 10 motivating factors to not wear a splint. Additionally, it identifies 6 positive outcomes of wearing splints, 6 negative outcomes of wearing splints, 3 positive outcomes of not wearing splints and 3 negative outcomes of not wearing splints. Requirements for an improved splint design are established and form the basis of the design for a prototype personalisation toolkit. Testing of this toolkit reveals that patients are keen to own more than one splint and personalise splints to match the scenario in which it is to be worn. Patients reported that they expected to be more compliant with a personalised splint when compared to their current splint.</div

Human Computer Interaction and Emerging Technologies

The INTERACT Conferences are an important platform for researchers and practitioners in the field of human-computer interaction (HCI) to showcase their work. They are organised biennially by the International Federation for Information Processing (IFIP) Technical Committee on Human–Computer Interaction (IFIP TC13), an international committee of 30 member national societies and nine Working Groups. INTERACT is truly international in its spirit and has attracted researchers from several countries and cultures. With an emphasis on inclusiveness, it works to lower the barriers that prevent people in developing countries from participating in conferences. As a multidisciplinary field, HCI requires interaction and discussion among diverse people with different interests and backgrounds. The 17th IFIP TC13 International Conference on Human-Computer Interaction (INTERACT 2019) took place during 2-6 September 2019 in Paphos, Cyprus. The conference was held at the Coral Beach Hotel Resort, and was co-sponsored by the Cyprus University of Technology and Tallinn University, in cooperation with ACM and ACM SIGCHI. This volume contains the Adjunct Proceedings to the 17th INTERACT Conference, comprising a series of selected papers from workshops, the Student Design Consortium and the Doctoral Consortium. The volume follows the INTERACT conference tradition of submitting adjunct papers after the main publication deadline, to be published by a University Press with a connection to the conference itself. In this case, both the Adjunct Proceedings Chair of the conference, Dr Usashi Chatterjee, and the lead Editor of this volume, Dr Fernando Loizides, work at Cardiff University which is the home of Cardiff University Press
