Those who are paralyzed must rely on a caretaker to complete day-to-day tasks and remain mobile. To combat this issue, research has been conducted to leverage visually evoked potentials using electroencephalography (EEG) to control wheelchairs. However, most of the resulting products from this research have been expensive and inaccessible to patients.

To address this issue, DiscoverSTEM students have developed an inexpensive attachment for wheelchairs such that any power wheelchair can be easily converted to an EEG-controlled wheelchair. After extensive research on both the P300 and the steady-state visually evoked potential (SSVEP) paradigms, DiscoverSTEM students found that SSVEP is the more practical paradigm for applications related to real-time selections, such as when the user is driving the wheelchair.

DiscoverSTEM students have designed a prototype EEG-controlled wheelchair that consists of an EEG headset, a laptop, a Raspberry Pi circuit, a servo motor, a 3D printed fork to guide a joystick, and a joystick-controlled electric wheelchair. Our innovation can easily be attached to any electric wheelchair with a joystick without damaging or permanently modifying the wheelchair. The system is also portable since the connection between the headset and the laptop is via Bluetooth and the connection between the laptop and the Raspberry Pi is via the user datagram protocol (UDP).

I am a 14-year-old freshman attending Brighter Horizons Academy in Garland, Texas. I have extensive experience with marketing, as I have been a part of various companies and mentorships. I graduated from the DiscoverStem program, allowing new doors to open up for me, and change the way I see things. The DiscoverStem program has also given me more experience with concepts such as patents, invention, and innovation, as well as inspiration to use these skills to help the world around us.

DiscoverSTEM founders Mirza Rizwan and Mirza Faizan have made history by becoming the first Indian to win the coveted George Washington Honor Medal from the Freedoms Foundation – USA.

Started in 1949 by former US President Dwight D. Eisenhower, Freedoms Foundation honors exceptional contributions of Americans towards communities in the USA. Generally reserved for the US citizens, the awarding organization made an exception to recognize the stellar research work and its impact of India’s Mr. Rizwan in designing and implementing a unique STEM & Innovation program for American children, thereby revolutionizing the education system in the USA.

Few of the other notable non-US citizens who have received George Washington Honor Medal include Ms. Margaret Thatcher (Former Prime Minister of United Kingdom), Lech Walesa (Former President of Poland and Noble Prize winner) and world-renowned Russian writer Aleksandr Solzhenitsyn. As the latest recipients of this prestigious honor, Mirza brothers join historically acclaimed group of citizens whose work and dedication advance the American ideals, the award letter says.

Some of the distinguished US citizens who have received this award for their stellar contributions in their field are Walt Disney, Astronauts Sally Ride and John Glenn, Capt. Sully Sullenberger, Athletes like Arthur Ashe, George Foreman and Tiger Woods and famous US educator Jaime Escalante.
