Abstract
This paper proposes a fingertip handwriting alphanumeric character recognition system based on hidden conditional random field HCRF model to provide an alternative for human–computer interaction Traditional handwriting recognition systems are limited because they require a specific or expensive input device such as pen tablet or touch panel Recently cameras have gradually become standard components in many computerbased products Therefore a fingertip and camera combination provides a flexible and convenient input device This proposed system combines fingertip detection trajectory feature extraction and character recognition First fingertip moving trajectories are tracked and recoded Then the stroke features are extracted from the trajectories as features Finally the proposed system adopts the HCRF model to recognize handwritten characters Experimental results show that the proposed novel input system is feasible and effective This study also presents possible applications for camera input devices
