To interact with stereoscopic images through 3D air-touch technology, the depth information for a touched 3D virtual object and the fingertip position should be aligned accurately. However, the fused 3D position is affected when the virtual object is blocked by the fingertip. Additionally, the 3D image with a large disparity decreases 3D touch accuracy. In order to improve the touch accuracy, virtual references and 3D image feedback were introduced respectively, and the touch accuracy was more than 90% based on a human interaction experiment.
