Blurry (Sticky) Finger: Proprioceptive Pointing and Selection of Distant Objects for Optical See-Through Based Augmented Reality

We demonstrate “Blurry (Sticky) Finger” in which one uses the unfocused blurred finger, sense of proprioception, to aim, point and directly select a distant object in the real world with both eyes open. We showcase two demo applications. The first illustrates the accuracy and usability of the proposed method with the target objects lying at a fixed depth on a monitor. The second is an AR based object inquiry system, a more practical application. The user aims and encircles a real 3D object whose image is captured with the eye-to-camera offset compensated. The image is searched through the data base with the result augmented on an OST display.
