| The three characteristics of virtual reality technology,Immersion,Interaction,and Imagination,are reflected in the interior decoration and real estate sales.By investigating the advantages and disadvantages of the relevant software in the market and obtaining feedback from comprehensive market research,the paper proposes a design scheme for a virtual home improvement system,and presents a low-cost,embeddable sensory interaction method that enhances the experience.Firstly,the dissertation designs a hardware-based hardware control part based on the MPU6050 gyroscope to realize the sensor interaction in virtual reality interaction at low cost.The hardware control part can be embedded in the real object to perform real-time angular attitude control with the virtual 3D object.The MPU6050 communicates with the Arduino main control board serial port to pack the data,and uploads the data to the Unreal Engine4(Unreal Engine)independent thread processing control via UDP protocol.The 3D furniture model display module combines traditional interactions to make the system more diverse in interaction,and it also adds interest and experience.Second,in order to enhance the sense of authenticity and experience,the sensor interaction hardware control module uses the quaternion method to represent and solve the attitude.The paper gives the conversion process of quaternion and Euler angles and the flow of Kalman filtering algorithm.The background of the paper constructs a linear equation,corrects the error caused by angular velocity integration,obtains the optimal value of the attitude data,and improves the accuracy of the tracking of the 3D model and the embedded hardware device.Furthermore,the paper uses Unreal Engine4 as a virtual home improvement system development platform and BluePrints and C++as programming languages to implement the key interactive technology application of virtual reality in the virtual home improvement system.The paper improves and optimizes the traditional interactive functional design such as viewing angles,switching model materials,switching lights/TVs,users can re-design home improvement style according to their preferences,choose furniture style color to resize and reposition their positions,add particles Special effects such as flame and water flow further enhance the authenticity of the system.Finally,the dissertation tests and analyzes the system as a whole and the functions of each unit.The test results show that the system not only accomplishes the above functions,but also saves the time cost of the home improvement company’s communication with the user on the traditional interaction function.The realization of the implementation of low-cost investment to enhance the sense of immersive system and experience,there is a better user experience and market prospects. |
