A wearable handwriting system for time-warping collocation

Abstract

This paper presents our new wearable handwriting input system that tracks user's index finger in the air and the finger loci are stored to the user location as handwriting and the handwritings can be shared by users as virtual scribbles and/or messages in the air. Our proposed method detects the finger locus to the location by descending the user's head motion from finger tracking reading. Their head posture is calculated in semi real time by integrating the image processing from the head-worn camera images into acceleration/gyro sensor readings equipped with the head-mounted display.
