What we wear (our clothes and wearable accessories) can represent our mood at the moment. We developed Emolleia to explore how to make aesthetic wears more expressive to become a novel form of non-verbal communication to express our emotional feelings. Emolleia is an open wearable kinetic display in form of three 3D printed flowers that can dynamically open and close at different speeds. With our open-source platform, users can define their own animated motions. In this paper, we described the prototype design, hardware considerations, and user surveys (n=50) to evaluate the expressiveness of 8 pre-defined animated motions of Emolleia. Our initial results showed animated motions are feasible to communicate different emotional feelings especially at the valence and arousal dimensions. Based on the findings, we mapped eight pre-defined animated motions to the reported, user-perceived valence, arousal and dominance and discussed possible directions for future work.

Robotic avatars can help disabled people extend their reach in interacting with the world. Technological advances make it possible for individuals to embody multiple avatars simultaneously. However, existing studies have been limited to laboratory conditions and did not involve disabled participants. In this paper, we present a real-world implementation of a parallel control system allowing disabled workers in a café to embody multiple robotic avatars at the same time to carry out different tasks. Our data corpus comprises semi-structured interviews with workers, customer surveys, and videos of café operations. Results indicate that the system increases workers’ agency, enabling them to better manage customer journeys. Parallel embodiment and transitions between avatars create multiple interaction loops where the links between disabled workers and customers remain consistent, but the intermediary avatar changes. Based on our observations, we theorize that disabled individuals possess specific competencies that increase their ability to manage multiple avatar bodies.
