Mixed reality system with ultrasonic virtual haptics

Abstract

The invention discloses a mixed reality system with ultrasonic virtual haptics, including a head-mounted optical device, an ultrasonic virtual haptic device and a portable data processing terminal. Ahead-mounted optical device is provided with an installation interface and can be integrated with the ultrasonic virtual haptic device. The head-mounted optical device includes a transparent diffraction flat display, a virtual image generation unit, a real scene acquisition unit, and auxiliary units such as a communication interface and power management. The ultrasonic virtual haptic device includes an all-transparent ultrasonic phased array, a driving unit, a power amplifying unit and an impedance matching unit. The portable data processing terminal is of a discrete structure, is connected with the head-mounted optical device and the ultrasonic virtual haptic device through a wireless network, and achieves functions such as two-way communication of information, physical environment reconstruction, space position extraction, virtual image generation and fusion and sound field parameter calculation. A highly flexible and contactless virtual haptic implementation method is provided for the mixed reality system, and the synchronization of the visual and haptic perception of the human body to a reconstructed environment is realized.

Description

technical field [0001] The invention belongs to the related technical field of mixed reality, and in particular relates to a mixed reality system with ultrasonic virtual touch. Background technique [0002] Mixed reality technology (Mixed reality, MR) is a further development after the fusion of virtual reality (VR) technology and augmented reality (Augmented Reality, AR) technology. Realize the coexistence of physical and digital objects, real-time interaction, and provide users with an interactive feedback information loop in the new visual environment, thereby enhancing the user's real experience. [0003] At present, most of this technology uses head-mounted optical devices (such as hololens, magic leap, etc.) to add graphics with specific functions to the visual information perceived by users (including the real physical world seen by human eyes and the virtual world constructed by computers). After the virtual functional graphics are generated, users can operate and i...
