ABSTRACT

Children’s online co-design has become prevalent since COVID-19. However, related research focuses on insights gained across several shorter-term projects, rather than longitudinal investigations. To explore longitudinal co-design online, we engaged in participatory design with children (ages 8 - 12) for 20 sessions in two years on a single project: an online collaboration platform with tabletop telepresence robots. We found that (1) the online technology space required children to play a role as technology managers and troubleshooters, (2) the home setting shaped online social dynamics, and (3) providing children the ability to choose their design techniques prevented gridlock from situational uncertainties. We discuss how each finding resulted from interplay between our long-term technology design and online co-design processes. We then present insights about the future of online co-design, a conceptual model for longitudinal co-design online, and describe opportunities for further longitudinal online co-design research to generate new methods, techniques, and theories.

Emerging research has demonstrated the viability of emotional communication through haptic technology inspired by interpersonal touch. However, the meaning-making of artificial touch remains ambiguous and contextual. We see this ambiguity caused by robotic touch’s "otherness" as an opportunity for exploring alternatives. To empower emotional haptic design in longitudinal out-of-lab exploration, we devise TactorBots, a design toolkit consisting of eight wearable hardware modules for rendering robotic touch gestures controlled by a web-based software application. We deployed TactorBots to thirteen designers and researchers to validate its functionality, characterize its design experience, and analyze what, how, and why alternative perceptions, practices, contexts, and metaphors would emerge in the experiment. We provide suggestions for designing future toolkits and field studies based on our experiences. Reflecting on the findings, we derive design implications for further enhancing the ambiguity and shifting the mindsets to expand the design space.

Sensory extensions enhance our awareness by transforming variations in stimuli normally undetectable by human senses into perceivable outputs. Similarly, interactive simulations for learning promote an understanding of abstract phenomena. Combining sensory extension devices with interactive simulations gives users the novel opportunity to connect their sensory experiences in the physical world to computer-simulated concepts. We explore this opportunity by designing a suite of wearable sensory extension devices that interface with a uniquely inclusive PhET Simulation, Ratio and Proportion. In this simulation, two hands can be moved on-screen to various values, representing different mathematical ratios. Users explore changing hand heights to find and maintain ratios through visual and auditory feedback. Our sensory extension devices translate force, distance, sound frequency, and magnetic field strength to quantitative values in order to control individual hands in the computer simulation. This paper describes the design of the devices and our analysis of feedback from 23 high-school aged youth who used our designs to interact with the Ratio and Proportion simulation.
