Lousa digital baseada em visão computacional

Abstract

The whiteboard which use is very known into all environments focused to studying and teaching, however, these frameworks have some limitations. To solve them, many digital whiteboard systems have been developed and launched on the market. Some of them have special surfaces that are able to identify the user‟s interactions and because of this, they have a very high price, preventing that some institutions acquired such tools. Trying to solve this problem, some low price whiteboards digital systems were developed. However, most of them use infrared. In this paper, we have developed a digital whiteboard using algorithms and techniques of computer vision – to indentify the user actions – together with the Windows standard API, used to perform the user‟s actions. At our project we used only the equipments already present in most of studying and teaching environments: whiteboard, projector, notebook and built- in webcam to the notebook. This allowed us discard the use of any additional equipment, as infrared.
