Gestures are one of the ways to interact non-verbally in HCI. Gesture recognition is used to convey information to a system or to control it; therefore it can replace some of the hardware devices used to control computer activities. Recognizing gestures in real-time became more feasible due to the advancements in the fields of pattern recognition and Image Processing. This is a documentation of a project that implements an algorithm that can be used to track and recognize hand gestures for drawing on a board. This algorithm depends on three steps: hand tracking, hand detection, and fingertip detection. For hand tracking the Mean- Shift algorithm is used, which is used to track non-rigid objects based on their histogram. For the hand segmentation, a simple background subtraction and threshold is used and it is also used to detect the fingertip of the pointer finger.enOctober university for modern sciences and artsuniversity of modern sciences and artsجامعة اكتوبر للعلوم الحديثة و الادابMSA universityUsing Pointer FingerInteractive Board WritingInteractive Board Writing On Board Using Pointer FingerOther
