This is the guest editors' foreword to the special issue on 2016 International Conference on Cyberworlds, which was held in Chongqing, China in September 28-30, 2016. The volume has 74 pages, consisting of six best full papers selected from the conference.

Many methods using gaze tracking have been proposed for realizing everyday interfaces for such devices as digital signage and HMD. This is because gaze expeditiously reflects the intention and thoughts of the veiwer. When using eye-tracking devices, we need to calibrate those devices for each viewer. We herein present a calibration-free method which allows the viewer to select the audio data through the detection of his/her gaze with a single webcam. As a result, we will be able to provide the viewer with an immersive environment where he/she can focus on the object easily. Also, we perform a preliminary experiment on the system with a motivation to apply it to audio-based guidance at a museum or an art gallery.

We propose a simple interface for novices to design 3D uid simulation through direct manipulation. In this article, we try to control fluid intuitively through direct manipulation, where parameters of fluid simulation are specified with hand motions. Recognizing specific hand motions to be captured through the use of Leap Motion as hand gesture commands allows the users to control the dynamics of 3D fluid at will, without detailed knowledge of fluid simulation.
