EyeAR: Refocusable Augmented Reality Content through Eye Measurements

The human visual system always focuses at a distinct depth. Therefore, objects that lie at different depths appear blurred, a phenomenon known as Depth of Field (DoF); as the user's focus depth changes, different objects come in and out of focus. Augmented Reality (AR) is a technology that superimposes computer graphics (CG) images onto a user's view of the real world. A commonly used AR display device is an Optical See-Through Head-Mounted Display (OST-HMD), enabling users to observe the real-world directly, with CG added to it. A common problem in such systems is the mismatch between the DoF properties of the user's eyes and the virtual camera used to generate CG.In this demonstration, we present an improved version of the system presented in [11] as two implementations: The first as a high quality tabletop system, the second as a component which has been integrated into the Microsoft Hololens [18].
