Abstract
Whiteboards are very popular in educational institutions, corporate sectors and other sectors, due to its economical, easy use and the most helpful communication tool between lecturers and students. On the other hand, In traditional learning, learners are usually take notes from the board, writing and erasing consume a lot of time and effort from learners and lecturer, and sometimes distract learner's attention, in other words, learners will not completely concentrate with the explanation which reduces the level of understanding, as a result, learners will not be interactive. And if some students are writing slowly or come late to lecture or havent a good sight, they cannot retrieve the written text in any way, but with WNTES they will retrieve any written text at any time easily.Whiteboards Note TrackingErasing system (WNTES) is an integral system that is able to capture the handwriting, and clean the board semi-autonomously, The basic operational principle of Note tracking part depending on tracking the IR light source, so when the user writing by the smart pen (Stimulus), the IR light will move with the hand movements in the same manner. This light will be detected by the Pixart IR camera which converts the IR blob into (X,Y) coordinates, then the camera chip transmits these coordinates to Uno Arduino by using IC (Inter-integrated Circuit) technology. Finally, the Arduino will transmit the whole data serially to the PC and by using C# (C Sharp Programming Language) program these data will be displayed on the PC monitor. WNTES consists of two parts: Tracking part and erasing part , to build tracking part some circuits must be designed, first of all, the IR pen circuit (IR Light Source), the IR-Sensitive Camera circuit, interfacing between these parts, and finally the programming part, also To build the Erasing part many steps must be follow first of all, select the whiteboard and build its frame, build the erasing head, build the mechanism of transition and select the drive and control systems.
