Social play is crucial for children’s well-being and development. However, many social play technologies fail to address the specific characteristics and needs of neurodiverse1 play and often overlook divergent play styles. To address this, we first conducted a co-design study with a neurodiverse group of 7 children (Age 7-8) and, based on insights from these sessions, then developed a prototype, ChromaConnect, that allowed children to express their play style to one another during play. To evaluate ChromaConnect’s ability to support neurodiverse social play in different contexts, we observed children using it in both structured and unstructured play settings. Our findings show that ChromaConnect enabled children to create a common language of play, made divergent play modes more visible, and facilitated explicit expression of social play initiation. We discuss how these findings could be used to design ‘accompanying social play things’ that are more inclusive of neurodiverse play characteristics and divergent play styles.

Social play is vital for healthy child development. Autistic and neurotypical children can often struggle to play together due to differing communication, play and interactional styles, resulting in reduced social interaction quality for both groups. Play technologies can facilitate and support social play among children. However, most play technologies to date attempt to encourage more neurotypical traits in autistic children in a bid to foster social play. This approach ignores the unique experiences of autistic children. We conducted a preliminary study combining an expanded proxy design and a technology probe observation with a group of 5-year-old children and their parents. We report on initial findings highlighting the importance of creating inclusive spaces for a cohesive and supportive play environment and reflect on using expanded proxy design when designing with young, neurodiverse groups of children.

Social play supports children to develop essential life skills and foster friendships. However, autistic and non-autistic children often do not have equal opportunities to engage in social play. Previous research to improve these opportunities tends to invoke social skill interventions solely for autistic children or is focused on designing for only one group, rather than considering the interactions or needs of all children in neurodiverse groups1. In order to understand the different experiences of children during social play, we conducted interviews with 6 professionals who support neurodiverse social play and undertook observation sessions of 36 autistic and non-autistic children during unstructured social play. Our findings move beyond the existing characterizations of autistic social play and build upon the double empathy problem to capture and consider the needs of all children in neurodiverse playgroups. We argue these findings could be used to inform future neurodiverse social play technology design in HCI.

Textural changes can be promising to give feedback on sportspeople's performance who needs less attention demanding modalities. However, previous research does not address which textural property's change would be more appropriate to give information in specific contexts, i.e. sports performance feedback. We focus on sport towels as a case to understand how to give feedback on sports performance through changes in textural properties. We address the gap by conducting experiments with 32 sportspeople to investigate (1) the textural properties (i.e. roughness) that can be perceived by sportspeople through a towel and (2) that can convey information on sportspeople's performance (i.e. smooth texture - good performance). The results indicate that hardness and bendability are appropriate to convey information about sportspeople's performance. To the best of our knowledge, this result is the first to explore that a change in the state of a textural property is able to give a specific feedback.

Flow state is a psychological state of optimal performance. To experience flow state, one needs to receive unambiguous feedback. Previous studies have described activities with internalized feedback modalities (e.g. visual). However, they do not offer any appropriate feedback modality for the activities that may benefit from external feedback, such as opponent-based sports. Addressing the issue, we adopted a research through design process and considered tennis as our case, in which players can benefit from attaining flow [1]. This pictorial reveals our approach to design 6 wearable device concepts under 3 design themes as future directions for design practitioners and researchers.
