in this project i use gesture sensor to read and interpret hand movements as commands to control an MP3 Player.

Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand.
Users can use simple gestures to control or interact with devices without physically touching them.

gesture controlled devices are so helpful for times like pandemic because they don't need physical touching.
