WiMi Hologram Cloud Inc., a leading global Hologram Augmented Reality (AR) Technology provider, announced the development of a computer vision-based 3D human-computer interaction system. With the help of VR technology, it builds a natural and intuitive 3D interaction environment and presents a 3D user interface. It provides a unified and human-centered interface for users and improves the naturalness and efficiency of HCI.
In a 3D HCI system, vision is the effective input modality. Computer vision is an AI technology that guides the system and interacts with the visual world, recognizing objects from the acquired inputs and providing the final result. Tasks such as acquiring, transforming, and analyzing digital images are included in computer vision to assist humans with recognition tasks and enable interactions. They are evaluated based on training data sets. The technology allows for greater and richer forms of information exchange for human-machine communication and helps to exploit the different cognitive potentials of humans and machines concerning each other.

The primary functions of WiMi’s 3D HCI system include human contour extraction, human behavior detection, and 3D HCI in a VR environment. Among them, human contour extraction is the first step of human behavior recognition, and whether the human contour can be extracted accurately directly affects the efficiency of human recognition. Human behavior detection is the key to HCI, and whether the computer can accurately understand human behavior is related to the regular operation of the system. The 3D HCI in VR uses static human action to interact with the virtual reality system.
The determined interaction information is sent to the VR system through image acquisition, image pre-processing, motion target recognition, interaction behavior detection, and other processing. The VR system provides the user with a manipulable 3D environment so that users can feel they are using motion to operate the system. Using human behavior for HCI is also the most direct and convenient way of interaction.
HCI in virtual reality has become closer to people’s lives. Its unique features of immersion, realism, and interactivity enable people to be immersed in it and form a computer application environment with interactive functions. In this case, WiMi’s computer vision-based 3D HCI system should have broad application prospects in security monitoring, entertainment games, and other fields.
