3D Vision

3D Vision

Intro:3D vision is a kind of technology that allow computers to perceive, reconstruct and interact with the 3D world based on vision sensors. It is not only a hot academic topic in computer science, but also crucial to many applications, such as virtual reality (VR) and augmented reality (AR). For achieving high-quality effects of VR and AR, we need to recover the 6DoF camera pose, 3D structure of the scene, and even the human interaction, so that people not only can see the lifelike virtual objects/scenes, but also the seamless fusion of virtual and real contents and even interact with them. We can leverage 3D vision technology to achieve this objective. For example, the simultaneous localization and mapping (SLAM) technique allows users to walk freely in a digital world wearing a VR/AR helmet by recovering the 6DoF movement of the helmet, and is also able to see the seamless mixture of real and virtual contents, and even the effect of their interaction with each other by reconstructing the geometry, textures and materials of the real environment. In this special issue, we have selected 6 papers (3 review papers, 2 research articles and 1 case report) covering 3 most relevant 3D vision techniques for the VR/AR applications, including SLAM, 3D reconstruction, object segmentation and tracking.

Human-computer Interaction

Human-computer Interaction

Intro:Human-computer interactions constitute an important subject for the development and popularization of information technologies, as they are not only an important frontier technology in computer science but also an important auxiliary technology in virtual reality (VR). In recent years, Chinese researchers have made significant advances in human-computer interactions. To systematically display China's latest advances in human-computer interactions and thus provide an impetus for the development of VR and other related fields, we have solicited articles for this special issue from experts in this area to participate in the review process. The following articles have been selected for publication in this special issue.

Haptic Interaction

Haptic Interaction

Intro:Touch is an important channel for human beings to communicate with the external world and plays a crucial role in human interaction with nature. Information such as softness, friction, texture and warmth, or more complicated human emotional communication can only be perceived by the act of touching. Despite its importance, it is striking that haptic feeback in human-machine interaction is still in its infancy. For example, a human user can enjoy realistic visual or auditory experiences facilitated by a computer through devices such as a head-mounted display or a stereo headset. However, haptic experiences that the user can obtain is extremely limited during such interactions. Haptic interaction technology enables users to touch virtual objects and experience tactile sensations, including contact force, softness, texture, weight, vibration, and temperature. These sensations can significantly enhance users' interactive experience of virtual-reality systems. Haptic interaction technology can be applied in many fields, such as surgical simulation/ training, virtual assembly and maintenance of complex mechanical equipment such as aircraft engines, interactive entertainment experiences such as movies and computer games.
