Air Presenter is a versatile Human Interface Device (HID) specifically designed to give lecturers greater mobility and control during presentations.
Lecturers often struggle with limited mobility during presentations due to the need to stay near their computers to control and annotate slides. This restriction reduces audience engagement and disrupts the natural flow of teaching. Traditional presentation controlling remotes provide limited features, further constraining presentation effectiveness.
The idea is to design a wearable presentation controller called Air Presenter that allows lecturers to control their presentations wirelessly, annotate slides, and interact with the audience.
The solution is the development of the Air Presenter, using an ESP32 WROOM 32U Board and a MPU 6050 sensor to track arm movements and translate them into precise cursor control. The device also features tactile push buttons for quick access Software Laser Pointer in Microsoft PowerPoint, Annotation Pen, Erase All Annotations and Drawing.
The development of Air Presenter involved designing a gesture-based wireless controller using an ESP32 WROOM 32U as the processing & communication unit and MPU6050 sensor as the gyroscopic data collector. Custom Bluetooth HID library specifically designed for this enabled seamless cursor and button controls. Through multiple prototypes and C/C++ code optimizations, the device was refined for enhanced mobility, precise motion tracking, and improved presentation interaction.
