Research On Product Interaction Based On Virtual Reality

This project is devoted to the development of virtual reality shooting training system based on Unity 3D engine and HTC vive virtual reality solution.The design and design points of virtual reality interaction design are discussed through the development of shooting training system.The main purpose of the system is to improve the shooting training effect of the soldier's new firearms,reduce the safety hazards and training costs of the shooting training,and break the traditional shooting training has high requirements for the site,complex approval,and large amount of firearms maintenance work.The main content of this topic includes system requirements function design,virtual reality scene design,virtual reality interaction interface design,virtual reality gripper interaction design,shooting performance prompt analysis method,etc.,to establish a security-free,complex maintenance-free maintenance.Virtual reality shooting training system with low environmental conditions and high feedback.This topic analyzes the current situation of shooting training system and virtual reality related technology,expounds the shortcomings of traditional shooting training and the advantages brought by virtual reality training system.Secondly,it uses 3Ds MAX and Unity 3D engine development platform to construct virtual reality scene.Simulate real shooting range,training hall and actual training environment;use HTC VIVE virtual reality solution to connect user and virtual reality training environment;use PLAYMAKER for visual programming,form logical judgment,reserve data input interface;use PHOTOSHOP and Unity engine The graphic interactive interface design is carried out;the Arduino is used to test the prototype function of the gripper,and finally the reasonable interaction between the trainee and the virtual reality shooting training system is completed.The content of this topic has the following aspects:1.3D restoration of real scenes.The virtual reality environment is modeled by using 3Ds Max and output to the Unity3D engine to create a texture texture to form a virtual reality interactive simulation environment.2.The writing of interactive control logic programs.Through the analysis of the use process of the shooting training system,the HTC VIVE and HID protocol modules are used for data acquisition and input,and the PLAYMAKER performs logical judgment execution to realize scene switching;the shooting effect is realized and the results are visually displayed and graphically analyzed;Implementation and switching.3.Human-computer interaction interface design in virtual reality environment.Through the test in the virtual reality envirorunent,the distance between the human-computer interaction interface and the operator,the size of the human-computer interaction interface,the size of the human-computer interaction interface,the dense arrangement of the buttons,the interface design richness and the recognition degree are tested and designed.And implementation.4.Design and implementation of the gripper.Through the design of the rifle model,the rifle model has the same weight and center of gravity as the real rifle;the function buttons are added without violating the holding posture,so that the user operates smoothly and is easy to remember.Use sensors to reduce user operations,achieve intelligent control,and optimize user experience.5.Interaction design of virtual reality systems.Through the analysis and design of the prototype operation experiment,the user can quickly grasp the software and hardware of the virtual reality environment and the virtual reality shooting training system in a short time and less steps,so as to start training;use the virtual reality platform to build a high immersive shot.The training environment completes the simulated shooting action through virtual reality software and hardware.Finally,the virtual reality shooting training system is established through Unity3D engine and HTC VIVE to optimize the training effect of recruits.The training system attempts to explore issues such as solving training site limitations,difficulty in maintaining firearms,high safety hazards in training,strong dependence on training venues,and high risk of shooting training.Trainees can be free from time and place restrictions,and can achieve self-correction and error operations during training,and realize the system's intuitive evaluation of training results.The whole paper strives to combine theory with practice.It is hoped that this design can meet the training of trainees and has certain reference significance for the future virtual reality interaction design.
