Abstract
Building on the work carried out in the context of both the master's thesis and the EUGLOH Tromso Idea Camp 2024, this paper proposes to explore somatic relationships that could help to develop a grammar of practical applicability that specifies which properties pertain to each the three dimensions of Emotional Design presented by Donald Norman. Thus, a proto-ontology affecting some of these factors is presented. The validity of this proposal was methodologically tested mainly through the use of Cultural Probes, along with other methodological tools, which were used to collect emotionally relevant artifacts owned by the participants. This data was submitted through both Content Analysis and Artifact Analysis in order to determine which properties of the artifacts made them meaningful to the users. Different preliminary data related to the three dimensions of Emotional Design emerged: in the first visceral dimension, elements of a perceptual-sensory nature; in the behavioral dimension, some preliminary factors relating to the prevalence of both feedback and image schemas stood out; lastly, the reflective aspect proved to be the one where the most properties were determined, mainly related to symbolic properties.

Abstract
This research aims to leverage digital drawing as a non-verbal language to transcend the communication barriers faced by individuals with partial to complete locked-in syndrome (LIS). It will explore the possibility of using the human body as an interface, through assistive technology, in accordance with its limitation in functionality, to facilitate social reconnection and emotional expression through drawing. This approach is grounded in the understanding that creative expression and communication are fundamental human needs and can significantly impact the well-being and quality of life of individuals with severe motor impairments. This paper will focus on the development of the drawing activities. These activities will run under a mixed reality set that can be tailored by caregivers or therapists to the end-user's needs and preferences, ensuring functionality and user satisfaction through an accessible, enriching, and emotionally rewarding experience. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Abstract
Within the context applied to Virtual Reality research, the present work focuses on a literature review within the emerging field of Transformative Experience Design: a domain in interaction design that aims to create experiences fostering self-actualization and self-transcendence and which relates directly to the ideas of the sublime or awe. The methodological Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) Statement was used to conduct the current review. The scientific multidisciplinary databases used for the search were SCOPUS and Web of Science. The initial search resulted in the collection of a total of 448 articles from the two aforementioned databases, of which 408 were included after the English language criterion had been applied. After eliminating duplicate studies, 304 articles remained. Here, the initial screening phase was based on reading the respective abstracts and titles, and from this excluding noticeably irrelevant studies based on the inclusion/exclusion criteria, resulting in a total of 71 articles. Of these, and after the full-text reading, 49 papers were considered eligible for inclusion in this research context.The work focuses on studies that have adopted a strongly empirical, phenomenological and qualitative approach to the creation and evaluation of transformative experiences in VR, with the purpose of finding out not only how these are being created, but also which are the main factors that enable a transformative dimension in this type of experiences. Indeed, VR seems to be explored through it´s particular phenomenological affordances as a means to advance the two fundamental dimensions of Transformative Experience Design: perceptual vastness, on one hand, and need for accommodation, on the other.Concerning the first dimension of perceptual vastness in VR experiences, different properties stood out. Firstly, the typology of the perceptual stimuli used was found to be mainly concealed between the representation of natural scenarios, and, most importantly, Earth´s view from outer space. It was also noted that environments that present an almost exaggeratedly extensive structure and where greater horizontality prevails are those that, according to this data, appear to have the best chance of fostering awe. Rather more interestingly, it has been revealed that the design of spaces and paths that present a dynamic and dramatic structure is where the sensations of awe are most prevalent, based, above all, on a feeling of surprise.On the other hand, the more epistemic dimension of need for accommodation appears to be based upon the exploration of paradoxical, supernatural, uncanny elements, mainly founded on the violation of the laws of reality and that beg for the accommodation within our current mental schemata. Truly, VR design allows for a complete inversion of these laws, and the use of fantastic and unreal elements thus finds fertile soil to then develop an experience that is deeply transformative.These results are then systematized and discussed, and further possibilities are then suggested within this context.

Abstract
Informal caregiving for People Living with Dementia (PLD) presents multifaceted challenges encompassing emotional, practical, and societal dimensions. This study explores the experiences of informal caregivers in Portugal and investigates the potential role of technology, particularly mHealth solutions, in addressing their needs. A mixed-methods approach incorporating questionnaire surveys and semi-structured interviews gathered insights regarding participants' caregiving experiences and technology usage. Findings reveal prevalent emotional challenges, practical limitations, and societal stigmas caregivers face, underscoring the need for enhanced support systems. Moreover, the study identifies deficiencies in mobile apps designed for caregivers and highlights the potential of Emotional Design (ED) principles to address these shortcomings. Future research should focus on validation, longitudinal studies, and co-design approaches to develop targeted interventions that support informal caregivers of PLD in Portugal and beyond. This study deepens understanding of informal caregiving and highlights the need to integrate emotional considerations into mHealth solutions to enhance caregiver wellbeing and dementia care outcomes. © 2025 The Author(s).

Abstract
The use of gamified crowdsourcing mechanisms through serious games and games with a purpose (GWAPs) has emerged as an effective motivational strategy for enhancing performance in human intelligence tasks (HITs). In this systematic literature review, we examine the underlying characteristics of competitive and cooperative player-oriented GWAPs and how they can be leveraged to optimize crowdsourcing performance in completing batches of HITs. By exploring gamified crowdsourcing elements in GWAPs, we can evaluate the impact of these two types of player behaviors (i.e., competition and cooperation) on motivation and performance. We reviewed 27 publications and grouped them into five categories: player orientation, game elements and motivation, crowd work optimization, gamified knowledge collection, and comparative studies and best practices. Our research pinpoints the significance of intuitive task instructions, alignment of game elements with player motivations, and the role of competitive and cooperative dynamics in enhancing engagement and performance.

Abstract
As competitive and cooperative dynamics gain prominence in games, they present unique opportunities to study player behavior. This paper explores the orientations of different player types, as categorized by Bartle’s Taxonomy, through the lens of a Game With A Purpose (GWAP) called BartleZ. Bartle’s Taxonomy identifies four distinct player types–Achievers, Explorers, Socializers, and Killers. This study delves into how these different types approach competitive and cooperative gameplay, through structured dilemmas in BartleZ. Results with 45 participants, reveal that player orientations significantly influence engagement and decision-making. Achievers balanced both strategies; Explorers favored cooperation; Socializers consistently chose cooperation; and Killers preferred competition but adapted in some contexts. Overall, players leaned toward cooperation early on, with a shift toward competition as complexity increased. Our findings pinpoint the importance of tailoring GWAP mechanics with diverse player motivations, enhancing both engagement and problem-solving effectiveness. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.
