The work has been carried out as planned with significant progress made on the five research objectives (RO):
RO1: Development of a theoretical framework integrating multidisciplinary research on MBR (Mental Body Representations) and guiding the design of future BTE (Body Transformation Experiences) technologies: We are conducting studies investigating the effects of different sensory combinations and top-down influences on body perception, to contribute to the theoretical framework. Our work focuses on 1) the design and optimization of measures of MBR and 2) strategies, methods, and prototypes for BTE interventions, including the utilization of material metaphors to transform body perceptions. Key contributions include embodied design explorations that have led to critical knowledge synthesis and a pragmatic integrative approach combining design research with quantitative sensory neuroscience methods.
RO2: Identification, mapping, and validation of the most effective non-visual cue combinations and underlying top-down and bottom-up mechanisms for transforming MBR in terms of body appearance and capabilities: Using a full-body motion suit, sensors, and questionnaires, we built a data corpus (N>100) to model behavior-MBR relationships and study individual differences in sound effects. Additionally, we identified key sensory cues for anchoring sound to the body, examined their emotional impact, and explored spatial metaphors for altering perceived body capabilities.
RO3: Understanding and quantifying the within- and between-subject interdependence of MBR with behavior, emotion, and self-identity: Using our data corpus (RO2), we are analyzing interdependencies and have developed deep learning models for real-time MBR assessment. Additionally, we are working on sensory input optimization, along with innovative architectures enabling MBR inference on wearable and edge devices.
RO4: Investigation of the short- and long-term effects on MBR malleability and persistence, including longitudinal and field studies with representative populations: Our studies with individuals with anorexia nervosa and subclinical eating disorders revealed disturbances in sensory integration, altering body perceptions. Additionally, our research with physically inactive users and professional dancers which encompasses embodied design exploration sessions, controlled lab studies, and 4-week home studies, demonstrates how sensory effects evolve over time, influenced by exposure timing, metaphor types, and individual traits.
RO5: Laying the knowledge basis for new technologies supporting the “inner fashion” concept which uses smart clothing to shape body perception, as validated in real-life studies: We are designing BODYinTRANSIT interactive gear through user-centered iterative approaches. We ran various thematic workshops in the form of embodied design explorations engaging various user cohorts (physically inactive, professional dancers with body concerns, general population). Art-science residencies contributed creative solutions. We are developing a toolkit for optimizing BTE wearables for real-life use.
The results of these activities have been disseminated through publications, conference presentations, seminars, demos, a dedicated website, social media, public events, and artistic performances. Notably, we organized an international conference on Body Representation.
These activities have been made possible through the establishment of a new laboratory known as i_mBODY Lab - Interactive Multisensory Body-centred Experiences at the Intersection of Neuroscience & Technology. This innovative lab integrates a maker space for prototyping, experimental testing capabilities and resources for sensory stimulation and body tracking.
