STEM-project "Head Tracker"

STEM Project "Head Tracker - an interactive microcontroller-based head movement tracker" 

Short name of the project: Head Tracker

Project author: Hanna Savitska 

Head Tracker is an innovative coordinate device based on an ESP32 microcontroller with integrated Wi‑Fi and Bluetooth controllers for controlling the cursor and sending commands to a computer using head movements, replacing a mouse while the user is working on a PC. 

The author of the "Head Tracker" device is computer science teacher Hanna Savitska. 

Idea: "Wouldn't it be cool to turn your head and have the mouse cursor follow your movements while working on a personal computer?" Style of work on the project: independent creation of your own device for communication between a person and a personal computer. 

The goal of this STEM project is barrier‑free, inclusive IT education. S

tages of work on a STEM project: 

Science. Search for information on the interaction of software environments, boards, sensors, and batteries for project implementation. Technologies. Programming the device. Engineering. All components of the device are placed in a plastic box that is easily fixed on a person's head. Mathematic. The cost of materials is about $25. 

Advantages of the project device: 1. Low cost - available components are used 2. Autonomy - battery power, independence from external sources 3. Flexibility of connection - Wi-Fi, USB, Bluetooth 4. Versatility - software is open to changes and adaptation 5. Scalability - easily integrated into educational or laboratory complexes and programs 6. Barrier-free inclusive IT education 7. Versatility of use: adults, children, people without health restrictions and with physical limitations 8. Ease of transportation

 Head Tracker offers a new approach to IT learning and virtual communication with a strong emphasis on practice and real‑life application of skills. Head Tracker can bring global opportunities to inclusive STEM education and promote equal access to education for citizens of Ukraine and the world. Students in grades 4-9 test the device during computer science lessons throughout the year.
