Real-time pen input system for writing utilizing stereo vision


Raid, Fadi Imad Osman Abu and Syed Ahmad, Sharifah Mumtazah and Hashim, Shaiful Jahari and Samsudin, Khairulmizam and Ali, Marwan (2018) Real-time pen input system for writing utilizing stereo vision. Journal of Computers, 13 (9). 1000 - 1009. ISSN 1796-203X


A system that captures handwritten words on a piece of paper utilizing two cameras which observe and track a pen’s tip lateral movement is presented. The system tracks the pen’s tip in real-time based on the two images vision using colored markers. The stereo camera is calibrated for accurate threedimensional (3D) positioning of the pen’s tip. Pen’s tip 3D coordinates are then being used to re-construct the handwritten input into computer image. Experimental results show that the system can detect and track handwriting within 1mm accuracy on the y-axis and 7 mm accuracy on the x-axis (depth).
