SpatialWhiteboard: A New Wearable Air-Writing Interaction with Kinect Sensor and Vibrating Ring Interface
(The Eurographics Association, 2015) Yeom, Kiwon; Han, Hyejin; Oh, Yoonsik; Kwon, Jeunghum; You, Bum-Jae; B. Solenthaler and E. Puppo
SpatialWhiteboard is a spatial finger writing system that enables complex spatial interactions through 3D handwriting via a Kinect sensor and vibrating ring interface. By incorporating depth and skin color information, we can directly separate the hand from the cluttered background. We can also accurately differentiate the fingertip from the hand by a mixture model of distance transforming and osculating circle. Users receive physical feedback in the form of vibrations from the wearable ring interface as their finger reaches a certain 3D position. Thus, it is now conceivable that anything people can do on contemporary touch based devices, they could do in midair with a pseudocontact interface.
