Due to this reason, it is feasible to develop computer-vision-based human-computer interaction systems. A vision-based continuous Graffiti™-like text entry system is presented. The user sketches characters in a Griffiti™-like alphabet in a continuous manner on a flat surface using a laser pointer. The beam of the laser pointer is tracked on the image sequences captured by a camera, and the corresponding written word is recognized from the extracted trace of the laser beam. © 2004 Society of Photo-Optical Instrumentation Engineers.EnglishComputer visionGraffiti recognitionHuman-computer interactionTrackingWearable computingElectronics industryHuman computer interactionImage processingLaser beamsPattern recognitionSystems analysisTracking (position)Wearable computersComputer industryExtracted traceGraffiti recognitionImage sequencesLaser pointerComputer visionArticle10.1117/1.1645257
