This hands-on course introduces participants to the design and development of the "Protect Me" Device—a wearable alert system that helps prevent unconscious hand-to-face contact. Ideal for those interested in health-focused technology, embedded systems, and behavior-modification tools, the course guides learners through building a smart wearable using sensors and microcontrollers.

Participants will learn to use proximity detection (e.g., ultrasonic, infrared, or IMU sensors) to detect when a user’s hand approaches their face. The device triggers a warning alert (such as vibration, light, or sound) to help reduce the risk of spreading germs or developing bad habits like face touching.

Key Topics Covered:

• Health & Behavioral Context:Understand the importance of minimizing face-touching for personal health and public safety, especially during outbreaks of illnesses like COVID-19 or the flu.
• Sensor Technology:Learn to work with motion sensors (like accelerometers) and proximity sensors (such as IR or ultrasonic sensors) to detect hand movement and distance.
• Embedded Systems & Microcontrollers:Gain hands-on experience programming microcontrollers like Arduino or ESP32 to collect sensor data and trigger alerts.
• Signal Processing & Alert Mechanisms:Learn how to filter and interpret data to accurately detect risky behaviors and design appropriate feedback mechanisms using vibration, sound, or lights.
• Design Thinking & Wearability:Explore ergonomic design and user-friendly features to make the device practical for everyday use. Consider power sources, form factor, and comfort.
• Prototyping & Iteration:Build, test, and improve your prototype through iterative design, debugging, and user testing sessions.

By the end of the course, learners will have built a fully functional prototype and gained skills in:

• Basic electronics and sensor integration
• Microcontroller programming (e.g., Arduino or similar platforms)
• Prototyping wearable technology
• User-centered design and iterative testing
