We present an interactive aerial-3D-touch user interface enabled by a holographic light-field display consisting of a holographic screen and a projector. 3D images are reproduced midair between the screen and a user, and the user can interact with the aerial 3D image. A technique to automatically align the 3D image and gesture sensing is developed to achieve direct-3D-touch interaction. It can be combined with a conventional 2D display thanks to the see-through capability of the volume holographic optical element. Some examples of 3D-touch interactions are demonstrated, such as 3D swipe, grabbing, object moving, and free-drawing. The experimental result of the usability evaluation is also reported.
