Abstract
This workshop study explores My Daily Badge (MDB), a wearable system that subtly translates biosignals (e.g., heart rate) into abstract patterns to represent emotions, aiding those with social cue challenges. A workshop with 12 participants (aged 16-27 years) revealed design principles: smooth shapes for positive valence, jagged edges for negativity, and complex patterns f or high arousal. The identified use cases included the enhancement of non-verbal communication, although it was noted that participants avoided displaying negative emotions in order to maintain social harmony. Younger users indicated a preference f or casual interactions, while older participants proposed applications for therapeutic and educational purposes. The study's findings underscore the potential of MDB for the subtle expression of emotion, but also highlight the challenges associated with priva cy, authenticity, and the ethical disclosure of emotion. This work contributes to the design of wearable technology for affective computing, emphasizing context-aware, socially harmonious solutions.
