Computer Vision Quiz through Hand Gestures Movements

Nowadays, computer-based multiple-choice exams are used universally in the recruitment, examination, and other processes. Making the setup for a computer-based test is very expensive because it requires a lot of equipment and software. We are working on a project that will employ computer vision to reduce the amount of hardware, like a keyboard and mouse, needed for computer-based exams. The suggested solution would use computer vision to display the question on screen after saving it to a csv file first. Second, we will search for hand movements in the air that can be used to respond to the presented questions using a webcam and computer vision. The automatic grading system in it will then display the grade. This approach made it easy to respond to questions and even made the evaluation procedure straightforward. To verify that no malpractice occurred during the exam, this technology ensures more security by counting the number of people who are in front of the webcam, if more than one person the exam automatically ends. This technique had a 95.7% success rate in accurately detecting hands. Importantly, because of very little technology is needed, the exam won’t be terminated in the middle due to a hardware failure or malfunction.
