Item type:Publication, Experiencing the World through Imperfect Lenses: An Autoethnography of Living in Mixed RealityMixed reality (MR) technologies are evolving to become more portable, incorporating video see-through capabilities, which enable a shift from stationary to mobile use. This development allows MR headsets to be used in various everyday contexts, including eating, travelling, and exercising. Before MR technologies reshape how we live and seamlessly integrate into our daily activities, we must understand the lived experiences of using MR in our personal lives and their influences and implications on our day-to-day activities. This paper presents an autoethnographic study that adopts an exploratory first-person perspective to uncover challenges and opportunities within this intimate context. We present the experiences and challenges of living in mixed reality, including on-the-go scenarios and social interactions. Our findings reveal issues such as social and ethical concerns and offer lessons learned to inform the design of future interactive systems for mobile mixed reality.Type:conference paperScopus© Citations 8 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, MRTranslate: Bridging Language Barriers in the Physical World Using a Mixed Reality Point-and-Translate SystemLanguage barriers pose significant challenges in our increasingly globalized world, hindering effective communication and access to information. Existing translation tools often disrupt the current activity flow and fail to provide seamless user experiences. In this paper, we contribute the design, implementation, and evaluation of \MRTranslate, an assistive Mixed Reality (MR) prototype that enables seamless translations of real-world text. We instructed 12 participants to translate items on a food menu using MRTranslate, which we compared to state-of-the-art translation apps, including Google Translate and Google Lens. Findings from our user study reveal that when utilising a fully functional implementation of MRTranslate, participants achieve success in up to 91.67% of their translations whilst also enjoying the visual translation of the unfamiliar text. Although the current translation apps were well perceived, participants particularly appreciated the convenience of not having to grab a smartphone and manually input the text for translation when using MRTranslate. We believe that MRTranslate, along with the empirical insights we have gained, presents a valuable step towards a future where MR transforms language translation and holds the potential to assist individuals in various day-to-day experiences.Type:conference paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Designing Grocery Shopping Experiences for Virtual RealityOnline grocery shopping offers time-saving efficiency and convenience, yet many people still prefer physical shopping for trust in food freshness and other sensory experiences. While online stores are evolving to offer new user experiences, such as supporting eco-friendly or ethical shopping, the desktop and mobile platforms limit the engagement of such experiences. Virtual Reality (VR) presents an opportunity to create immersive and rich grocery shopping experiences, closing the gap between the convenience of online shopping and the sensory experience of physical shopping. Yet, designing VR grocery stores remains relatively unexplored. In this paper, we investigate the long-term potential of VR grocery stores, focusing on meeting individual needs. Through a co-design workshop, participants brainstormed the design of product displays, in-shop navigation, shopping carts, social shopping, among others. Based on our findings, we provide design recommendations for future VR grocery shopping to develop meaningful alternatives to existing shopping experiences for groceries.Type:conference paperScopus© Citations 8 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Exploring User Perceptions on Visual CO2 Representations as Eco-Feedback in Virtual Reality(2025-04-26); ; ; Eco-feedback interventions primarily focus on lowering energy consumption behaviours instead of considering the impact of CO2 emissions resulting from the overall energy mix of renewable and non-renewable energy sources. Although labelling products with CO2 emission is an effective way for green nudging, consumers often perceive the information as intangible and incomprehensible. In this paper, we study the impact of the visual representation of CO2 equivalences (VisualRepCO2) on customers’ perceptions when choosing an energy supplier in virtual reality (VR) compared to a paper baseline and desktop setup. Our findings indicate that a VisualRepCO2 supports customers of electricity supplies in understanding their impact more comprehensibly and touches them more emotionally than a text label. We conclude by demonstrating lessons learned for future research and offering recommendations to support practitioners in enhancing customers’ understanding of CO2 emissions.Type:conference posterJournal:Extended Abstracts of the CHI Conference on Human Factors in Computing Systems (CHI EA ’25)Scopus© Citations 2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Being in the Zone: Investigating the Effectiveness of In-Vehicle Multi-Sensory Affective DisplaysPrevious research highlights the benefits of affective interfaces in improving drivers’ emotional state and performance. This poster investigates the impact of a multisensory affective display, encompassing visual, auditory, and olfactory stimuli. A preliminary evaluation with eight participants in easy driving conditions informed scent intensity and placement adjustments. In a subsequent study under more challenging driving scenarios, the majority of participants (14 out of 20) reported minimal awareness of the system, while self-reported less skilled drivers perceived the system, experienced distractions and cognitive overload. Our findings suggest that the effects of multisensory affective displays on drivers vary and are influenced by driving difficulty, driver skill, and mental state, such as the state of flow. Future research is encouraged to explore novel interface designs that consider drivers' skills and cognitive states to adapt accordingly.Type:conference poster - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Gaze into Fintech: Assessing the Influence of Financial Literacy on Interaction Behaviour Using EyetrackingFinancial technology (fintech) has become more accessible to diverse users, including finance practitioners and non-experts. We conducted a usability test with six participants, evaluating a fintech app using eye-tracking technology for finance practitioners and non-finance experts. Our analysis revealed that participants with limited financial knowledge had difficulty understanding financial information and navigating the software, indicated by a higher revisitation rate on financial labels. We also observed higher cognitive overload or uncertainty among non-practitioners, evidenced by gaze-click discrepancies. These insights aim to inform the design of more accessible fintech applications.Type:conference poster - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Sails up on a Sustainable Ocean: Informing Design through Autoethnography of a Seven-Day Sailing Expedition(2025-07-05)In this workshop opinion paper, I share a first-person account of my lived experience during a seven-day sailing expedition around Mallorca, with a focus on water sustainability. The paper highlights critical incidents from the journey that inspired reflection and informed design recommendations — opening up discussions on how to foster more symbiotic, respectful engagements with water across all forms of water sports.Type:discussion paper - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Sharing and Exchanging Realities through Video See-Through MR Headsets(2024-06)Humans often have a natural inclination towards exploring and sharing and the intricacies of daily life. This paper explores concept ideas of using video see-through capable mixed reality (MR) headsets to enable individuals to share and receive content diverging from traditional media forms. We propose four ways of sharing personal realities, considering reciprocity levels and temporal factors, encompassing unidirectional, bidirectional, synchronous, and asynchronous sharing. We further elaborate on some use cases for each way. The paper also addresses ethical concerns arising from MR sharing, such as privacy issues, the allure of experiencing life through others, and the potential effects on one's sense of personal reality.Type:discussion paper
