The Research And Realization Of Three-dimensional Space Mouse Based On STM32

With the rapid development of the Internet and electronic products,computers,smart TVs and other electronic products have entered every household.The mouse—as a computer input device,plays an important role in the computer operations.The appearance of the three-dimensional mouse,even it can replace the use of the traditional two-dimensional mouse,owing to the use of traditional mouse bringing a lot of inconvenience.On the one hand,the using of the traditional two-dimensional mouse will be limited to the distance and must touching the flat.In some cases,for example,when teachers use the computer for classes,or the company's staffs use the computer to present technology or product to the client,the speaker is not far away from the computer,and the mouse must be placed on a flat surface,it is not inconvenient for the two-dimensional mouse when operating a computer obviously.Although people can play the power point with the PPT pointing pen,it can't replace the mouse to operate the computer operating system completely.On the other hand,with the virtual three-dimensional space and the development of three-dimensional display devices,more and more people manipulate three-dimensional space equipment.It is not convenient to manipulate the objects in three-dimensional space by using a two-dimensional mouse.For example,now a lot of games are three-dimensional,the roles of the games are in the virtual threedimensional spaces for movement.Although the stereo sense is very strong,if you use the equipment operations manipulate the traditional two-dimensional space in threedimensional space characters or objects,it will bring people great inconvenience.The output device of the computer,the three-dimensional display can appear and gradually get a wide range of applications.The computer's content will be presented in a new three-dimensional form,It is forcing the input device of the computer—mouse that also shown in a new three-dimensional attitude,the three-dimensional mouse is bound to appear.This paper studies the space mouse and its application in virtual space.The space mouse uses STM32 as its MCU,The six-axis sensor MPU6050 collects the position information of the mouse and monitors the movement state of the mouse,The wireless module nRF24L01 sends the location information of the mouse in the space to the receiving terminal,The wireless module at the receiving terminal sends the data again to the STM32,the STM32 send the data to the computer via the USB interface,so the computer receives the position information and movement state of the mouse.The paper first carries on the feasibility analysis and the whole design to the space mouse,and then it analyzed the spatial mouse data processing,then the hardware and software of the space mouse were designed in detail,finally,it is the physical debugging.With the development of information technology,the computer is becoming more and more significant,In summary,it is necessary for us to research the three-dimensional mouse,it is great convenient to people's learning,working and daily life.
