MinWin
Turning invisible efforts into visible wins.
What is it?
MinWin is a 3D printed small, discreet smart keychain that helps children with social anxiety recognize and reinforce their daily efforts. Based on Cognitive Behavioral Therapy (CBT), it encourages children to focus on small acts of courage, such as making eye contact, speaking in class, or approaching classmates. Throughout the day, children independently record each effort on a scale of 1 to 5, receiving immediate feedback through light and vibration. At the end of the week, the device is placed on a docking station that visualizes the collected data, enabling the child and therapist to reflect on progress together. By making small achievements visible, MinWin helps build confidence and resilience over time.

How does it work?
MinWin combines a physical push button, an interactive LED scale, and a docking station. Built on an ESP32-C3 microcontroller running custom C++ firmware, the device accompanies the child throughout the day. Whenever the child overcomes a social challenge or makes a meaningful effort, they press the button and rate the effort on a scale from 1 to 5. The device immediately responds with gentle haptic feedback via an ERM coin vibration and a color-changing LED animation, reinforcing the connection between effort and achievement.
