Your inspiration

Inspired by the real dilemmas of autistic children and their caregivers, which we have come to understand more deeply with the development of the Internet – those moments of frustration caused by communication barriers, sudden emotional outbursts, and the urgent need of caregivers to "understand" the inner world of children. The core inspiration is: Can invisible internal physiological states be transformed into visible and understandable signals?

How it works

The Emotional Interaction Brooch is specifically desigued for children with autism. By integrating PPG heart rate, GSR skin conductance, and motion sensors, it can capture emotional fluctuations in real - time with an Al algorithm accuracy rate of 89.7%. It weighs less than 20g enabling unobtrusive wear. The LED breathing light and vibration feedback indieate the emotional state (green=calm, red=anxious) and it is linked with an APP that pushes intervention uggestions. The modnlar design supports hardware upgrades, and the materials an100% reeyelable. Cthical trials have shown a 43% reduction in emotional outbursts, helping ehildren integrate into soeial seenarios.

Design process

Requirement Definition and Technical Anchoring The team delved into special education institutions and discovered that autistic children exhibit measurable physiological signals before emotional outbursts—such as sudden heart rate spikes—but these are difficult to capture with the naked eye. This led to the identification of three core needs: real-time emotional visualization, unobtrusive wear, and caregiver collaboration. Ditching face recognition solutions, the team selected a bio-signal combination of PPG heart rate, GSR skin conductance, and motion sensors to ensure privacy and accuracy. Miniaturization and Algorithmic Breakthroughs • Hardware Iteration: Through flexible PCB lamination technology, the team reduced the initial 35g prototype to 18g. A custom 4mm miniature PPG module achieved a 3mm ultra-thin body. • AI Training: In collaboration with children's hospitals, over 2,000 hours of physiological data were collected. Using motion artifact elimination algorithms and cross-scenario training, emotional recognition accuracy was boosted to 89.7%.

How it is different

Technological Integration Breakthrough Miniaturizing medical-grade physiological monitoring (PPG heart rate + GSR skin conductance + motion sensing) into a 20g brooch, an anti-motion AI algorithm achieves 89.7% emotional recognition accuracy, overcoming the precision bottleneck of wearables in dynamic childhood scenarios. Dual-Channel Pressureless Interaction An original biological signal→natural metaphor conversion system: • Breathing LED (low-saturation red/green) mimics firefly light language to avoid visual stimulation; • Low-frequency vibration simulates heart rhythm to establish a private emotional feedback channel.

Future plans

Technological Deepening • Upgraded Multimodal Sensing: Integrated environmental sensors (light/sound pressure) map emotional triggers to predict anxiety-inducing factors. • EEG Interface R&D: Exploring non-invasive EEG modules to enhance emotional recognition dimensions. Ecosystem Expansion • Educational Integration: Linked with IEP (Individualized Education Program) platforms to generate emotion-adaptive curricula. • Public Space Support Network: Inductive terminals in libraries/hospitals adjust environments (e.g., dimming lights) when triggered by the brooch.
