Abstract

The invention relates to the technical field of court trial evidence display, and relates to a court trial virtual reality environment evidence display and switching method and device, and the method comprises the steps: 1, pressing a center button, and selecting an evidence model needing to be displayed; 2, using an index finger to press a front button of a handle grip to activate an acceleration sensor and an attitude sensor, and enabling a user to stretch a hand forwards to realize the reduction of the three-dimensional model and retract the hand to realize the amplification of the three-dimensional model; rotating the three-dimensional model around a vertical shaft by turning over the wrist up and down; rotating the model around a horizontal shaft through the internal rotation / external rotation wrist; 3, feeling the texture of the evidence model by holding a rubber sleeve with force feedback on the outer layer of the grip and a metal net; 4, shifting a left rocker to select a picture of the left part of the model, and shifting a right rocker to select a picture of the right part of the model; and 5, pressing the center button again, and exiting the current evidence model. According to the invention, court hearing participants are more focused and have stronger sense of participation.

Description

Technical field [0001] The present invention relates to the technical field of trial evidence, and in particular, there is an evidence display and switching method and device for a trial virtual reality environment. Background technique [0002] Virtual reality technology, also known as spiritual technology is a new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information, simulation technology, and its basic implementation is that computer simulates virtual environments to give people an environmental immersion. With the continuous development of social productivity and science and technology, the demand for VR technologies in all walks of life is increasingly. VR technology has also achieved great progress and gradually became a new scientific and technical field. [0003] Existing technology solutions include (1) using traditional human-computer interactive devices, including, mouse, keyboard, game handle, to resp...
