Research On Virtual Reality Interaction Design Based On User Experience

With the continuous development of computer simulation technology,various simulation platforms based on Virtual Reality(VR)technology have been greatly developed.At present,the hardware devices of many manufacturers emerge in an endless stream,but the devices have not formed standardized interaction modes,such as staring interaction,gesture interaction,gamepad interaction,etc.Many VR products still use the two-dimensional interface design method for their interaction interfaces,which leads to poor user experience.The interaction design method of VR environment needs further research.Firstly,based on the existing virtual reality and interaction design concepts,this paper analyzes the characteristics and application status of VR interaction interfaces different from traditional 2d interfaces,and summarizes the existing problems and deficiencies.The user experience of touch interaction mode and ray interaction mode in VR gamepad was measured and studied.Relevant experiments were designed,and the objective data and subjective scores were statistically analyzed to quantify the user experience.The experimental results show that touch interaction is more suitable for close precise interface interaction,and ray interaction is suitable for long precise interface interaction.Secondly,this paper analyzes the interaction state of users in the touch interaction mode.In order to get better user experience,two feedback modes suitable for virtual interaction are designed and proposed: visual feedback and tactile feedback of the handle.Then the visual feedback and handle user experience for the measurement of force feedback research,the experimental results show that the interfacial forward amplifier feedback and visual feedback is highlighting the handle profile feedback can prompt the user to handle the tactile feedback under the condition of strong feedback users think more touch effect,can simulate the real environment better user experience.Finally,taking the naval command analysis system as the design case,based on the Unity 3D engine and HTC Vive head-mounted device,the overall design of the system was carried out in combination with the experimental research conclusions.The usability test verifies the effectiveness of feedback in improving user experience,and provides new ideas and methods for the design of virtual command system in the future.
