We currently have a variety of white board softwares available for online instruction. Every piece of software has benefits and drawbacks. The fact that many typical whiteboard software programmes require hardware pointing devices or a touch-sensitive screen for interaction, such as a stylus, digital pens, mice, etc., is one of their key drawbacks. Therefore, we are introducing Virtual Teaching Board, which is a hand movement based writing in the air software, to avoid the use of such pointing devices and to make online learning more interesting and effective. Instead than using external hardware devices like a mouse, stylus, digital pens, etc. to write on the whiteboard, it uses a variety of hand movements with the fingertips in the air. It offers users a lighthearted setting. The Virtual Board Module, Presentation Module, and Calculation Module are the three modules that make up this project. In the Virtual Board module, we give the user interface functionalities for selecting the type of board (Normal or Blackboard), choosing the colour of writing, using an eraser, switching between presentation and calculator modes, and more. Users can write on the screen using different colours by simply waving their fingertip in the air in the Virtual Board Module's writing mode and board type, and they can entirely erase the board by waving five fingers across it. And by choosing Presentation mode, the user enters the Presentation module, where they can give a presentation by advancing and reversing slides with simple hand motions. In this project, we employed the Open-cv, Mediapipe, NumPy, and Python programming languages. By including certain other features like Physical properties and Physical Stimulations to the objects created on the virtual board in Stage-2, this programme can be upgraded even further.
