Danger-free code: schoolchildren have created a bracelet for people with epilepsy and a gesture detector for help

High school students have created a smart bracelet for recognizing epileptic seizures, a system for detecting gestures for help with automatic recording of an incident, and a computer model for optimizing the work of an ambulance. The developments are already being tested and may find application in urban infrastructure in the future. World First Aid Day is celebrated annually on the second Saturday of September. By this date, students of the capital's schools have prepared innovative projects designed to save lives and preserve health, the press service of the Moscow Department of Education and Science reported. For more information about this year's developments, see the "Izvestia" article.

A bracelet for tracking epileptic seizures

Alexey Yemelyanov, a student of the 11th engineering class at school No. 2086, has developed a prototype smart bracelet for people with epilepsy. The device constantly monitors the movements of the wearer, automatically records changes in the motor pattern and analyzes the data using the built-in machine learning model. If the wristband detects sudden, chaotic, and high-amplitude fluctuations along several axes at once, it automatically notifies medical services and emergency contacts listed on the phone about the possible onset of a generalized seizure.

— I collected and analyzed several hundred movement samples, more than 200 of which imitated an attack. The rest were recorded during normal daily activities such as walking, gesturing, and other natural movements. These data allowed us to teach the system to distinguish a dangerous condition from normal physical activity with an accuracy of 97.8%," the author of the project told "Izvestia".

In case of a false alarm, the owner can cancel the alarm through the mobile application. If no confirmation is received, the system sends an SMS and makes a call to a pre-specified number. In addition, there is an SOS button on the bracelet: you can press it when an attack is approaching to give an alarm yourself.

The Help gesture Detector

Another device was developed by Anna Polyakova, a student of the 11th engineering class of school No. 2120. She created the "Help Gesture Detector", a system that is mounted on a wall and recognizes a special gesture in real time. After that, the device gives a loud beep at the scene and sends a photo via a messenger bot.

Initially, the project was created to counter bullying in schools. Therefore, the system now sends an alarm signal to a social educator, but it can be reconfigured for use in other public places, such as train stations, airports, subways, shopping malls, and other crowded places where safety is particularly important.

— In addition to promptly processing information and sending an alarm, the device instantly captures evidence, which makes it difficult to hide the incident or shift the blame to another person. In the future, I plan to expand the functionality of the system and introduce special cards for employees to turn off alarms, since help buttons can sometimes be triggered accidentally. Then the system will need to be tested at school to identify flaws and make a finished product out of it," said the author of the project.

An optimization model for the ambulance service

Olga Olenina, Sofya Zyatnina and Veronika Gosteva, 11th grade students of the Vernadsky Avenue IT School, won the "Engineers of the Future" conference with technology for optimizing the emergency medical system.

— Ambulance services handle a huge number of calls every day. We decided to calculate how the construction of a substation in the area where our school is located — Troparevo-Nikulino — could help doctors and people who need help," Olga Olenina explained.

The high school students studied the area, analyzed its geography, transport accessibility and demographic indicators. Based on these data, they developed an agent-based simulation model that takes into account building density, road junctions, severity of calls, and time of day.

The schoolgirls chose a location for the building, created a computer simulation of the ambulance service and conducted scenario experiments. In addition, the students calculated the number of calls received by the nearest substations during peak load, and compared it with the actual capacity. Thus, the authors were able to calculate the required number of medical teams and machines at the substation.

In the future, the development may help urbanists and city authorities assess the need for the construction of new substations, for example, in areas with active development or in areas being renovated under a renovation program. The model has already been tested in the Laboratory of computer modeling of socio-economic processes at the Central Economic and Mathematical Institute of the Russian Academy of Sciences and was highly appreciated by its director.
