A social interactive whiteboard system using finger-tracking for mobile devices

Mobile devices have become a commodity in nowadays allowing people to get connected and perform several tasks for work. The usefulness of mobile is mobility leading people to solve their problems remotely, facilitating an everyday life. Based on these premises we propose a social interactive whiteboard system using finger-tracking for mobile devices. The application is a drawing tool, allowing users to create a virtual whiteboard and draw different kinds of lines, erase lines, zoom etc. from mobile devices that are featured with built-in projectors. Beyond the end-user application, this study investigates the problematic of tracking a finger using the build-in camera and how images are properly projected as a whiteboard from a mobile device. We present a thorough analysis of the various techniques that can be used to track a finger and depict our proposal to build the mobile-based interactive whiteboard application. The experimental evaluation analysed the performance, reliability and usability of the application taking into account valuable feedback for endusers.
