Playful E-textile Sonic Interaction for Socially Engaged and Open-Ended Play Between Autistic Children

Research on the potential benefits of technology for autistic children is an emergent field in Human-Computer Interaction (HCI), especially within the Child-Computer Interaction Community. This thesis contributes a design approach grounded in theories of play, cognitive development, and autism to expand the discourse on methodological guidelines for performing empirical studies with non-verbal autistic children and to extend the design space to cater to the socio-emotional and sensory needs of this population. The thesis reveals how sonic e-textile Tangible User Interfaces (TUIs) can be used effectively to mediate children’s social participation in playful activities. This is demonstrated through developing three explorative field-studies conducted at a specialist school based in North-East London where two sonic e-textile playful TUIs, namely Mazi and Olly, have been created and tested with three groups of autistic children aged between 5-10. The three studies ran over the period of three years and were designed to investigate the potentials of TUIs as shareable toys during leisure and recreational activities to a) support social and playful interactions among peers and b) provide opportunities for self-regulation. The key contributions of this thesis are the designs of two tangible user interfaces, which offer a set of design approaches to guide researchers through creating shareable and playful tangibles for non-verbal autistic children; a framework for analysis and a thorough evaluation process that other researchers could use to assess the efficacy of playful TUI designs for nonverbal autistic children; and an in-depth discussion about the research process, which offers a new perspective about holistic designs and evaluation of technologies that aim to scaffold play in groups non-verbal autistic children

Real-time 3D Graphic Augmentation of Therapeutic Music Sessions for People on the Autism Spectrum

This thesis looks at the requirements analysis, design, development and evaluation of an application, CymaSense, as a means of improving the communicative behaviours of autistic participants through therapeutic music sessions, via the addition of a visual modality. Autism spectrum condition (ASC) is a lifelong neurodevelopmental disorder that can affect people in a number of ways, commonly through difficulties in communication. Interactive audio-visual feedback can be an effective way to enhance music therapy for people on the autism spectrum. A multi-sensory approach encourages musical engagement within clients, increasing levels of communication and social interaction beyond the sessions.Cymatics describes a resultant visualised geometry of vibration through a variety of mediums, typically through salt on a brass plate or via water. The research reported in this thesis focuses on how an interactive audio-visual application, based on Cymatics, might improve communication for people on the autism spectrum.A requirements analysis was conducted through interviews with four therapeutic music practitioners, aimed at identifying working practices with autistic clients. CymaSense was designed for autistic users in exploring effective audio-visual feedback, and to develop meaningful cross-modal mappings of musical practitioner-client communication. CymaSense mappings were tested by 17 high functioning autistic participants, and by 30 neurotypical participants. The application was then trialled as a multimodal intervention for eight participants with autism, over a 12-week series of therapeutic music sessions. The study captured the experiences of the users and identified behavioural changes as a result, including information on how CymaSense could be developed further. This dissertation contributes evidence that multimodal applications can be used within therapeutic music sessions as a tool to increase communicative behaviours for autistic participants

Exploring expressive and functional capacities of knitted textiles exposed to wind influence

This study explores the design possibilities with knitted architectural textiles subjected to wind. The purpose is to investigate how such textiles could be applied to alter the usual static expression of exterior architectural and urban elements, such as\ua0facades\ua0and windbreaks. The design investigations were made on a manual knitting machine and on a CNC (computer numerically controlled)\ua0flat knitting machine. Four knitting techniques -\ua0tuck stitch, hanging stitches, false lace, and drop stitch - were explored based on their ability to create a three-dimensional effect on the surface level as well as on an architectural scale. Physical textile samples produced using those four techniques were subjected to controlled action of airflow. Digital experiments were also conducted, to probe the possibilities of digitally simulating textile behaviours in wind. The results indicate that especially the drop stitch technique exhibits interesting potentials. The variations in the drop stitch pattern generate both an aesthetic effect of volumetric expression of the textile architectural surface and seem beneficial in terms of wind speed reduction. Thus, these types of knitted textiles could be applied to design architecture that are efficient in terms of improving the aesthetic user experience and comfort in windy urban areas

A Designer’s Approach: Exploring how Autistic Adults with Additional Learning Disabilities Experience their Home Environment

Autistic adults with limited speech and additional learning disabilities are people whose perceptions and interactions with their environment are unique, but whose experiences are under-explored in design research. This PhD by Practice investigates how people with autism experience their home environment through a collaboration with the autism charity Kingwood Trust, which gave the designer extensive access to a community of autistic adults that it supports. The PhD reflects upon a neurotypical designer’s approach to working with autistic adults to investigate their relationship with the environment. It identifies and develops collaborative design tools for autistic adults, their support staff and family members to be involved. The PhD presents three design studies that explore a person’s interaction with three environmental contexts of the home i.e. garden, everyday objects and interiors. A strengths-based rather than a deficit-based approach is adopted which draws upon an autistic person’s sensory preferences, special interests and action capabilities, to unravel what discomfort and delight might mean for an autistic person; this approach is translated into three design solutions to enhance their experience at home. By working beyond the boundaries of a neurotypical culture, the PhD bridges the autistic and neurotypical worlds of experience and draws upon what the mainstream design field can learn from designing with autistic people with additional learning disabilities. It also provides insights into the subjective experiences of people who have very different ways of seeing, doing and being in the environmen

E-textiles for Self-Expression: Participatory Making with Blind and Visually Impaired People

This research explores how blind and visually impaired (VI) people can engage with e-textiles in creative and tactile ways, by making interactive e-textile art pieces to tell their own stories. Touch, gestures used to interact with textiles and e-textiles, and association of meaning with objects are central concerns of the work, in the context of how different materials can evoke and be used in self-expression. The research focuses on how VI participants can design and make their own e-textile objects, bringing in ideas of empowerment and agency, and drawing attention to what characterises an effective ‘participatory making’ environment. Three studies are reported. The first study observed practices at two schools for blind and VI children/young people to establish how ‘objects of reference’ are used within the classroom environment, and what other sensory stimulation is important. The second study involved two series of hands-on e- textile making workshops, at a charity for VI people, and at a contemporary art gallery, to explore how visually impaired participants can design and make personal e-textile objects. The third, a laboratory study, investigated what associations and gestures visually impaired participants used with e-textile sensors that had different textures and functioned in different ways. The research explored the potential of participatory making of e-textiles in terms of touch, personal association, accessibility, and creativity. The research identifies some effective practices for participatory making of e-textiles with visually impaired people, including a modular approach to circuit-making. It highlights the importance of ownership of the process for the participants. It demonstrates that, although there is ‘no common language of gesture’ for touch-based interaction with e-textiles, conventions can be established through example or consistent use. It outlines the ‘lessons learned’ in working with blind and visually impaired people, which can inform other researchers, designers, or artists interested in participatory making
