Hand Gesture Based PPT Controller

Presentations are essential in both academic and professional environments, yet conventional slide navigation methods often limit the presenter’s movement and interaction. Gesture recognition offers a more intuitive, hands-free alternative, removing the dependence on physical remotes or keyboards. This project presents a gesture-controlled system for managing PowerPoint slides and adjusting computer volume, leveraging embedded systems and wireless communication. The setup includes an APDS-9960 gesture sensor for hand gesture detection, an Arduino Uno for processing inputs, and an HC-05 Bluetooth module for transmitting commands to a computer. A custom-built desktop application developed with ASP.NET interprets these gestures in real time, allowing users to perform actions such as slide transitions, volume adjustments, and presentation pauses. The system is designed with accessibility in mind, aiming to support users with disabilities and improve the overall efficiency of presentations. By enabling touchless interaction, this solution enhances user experience and engagement. Future developments may include AI-based gesture recognition, support for multiple commands, and potential integration with AR/VR platforms to broaden its application in human-computer interaction.
