Multifunctional wearable human-computer interaction input equipment based on MEMS (Micro Electro Mechanical Systems) acceleration sensor

Abstract

The invention discloses a multifunctional wearable human-computer interaction input equipment based on an MEMS (Micro Electro Mechanical Systems) acceleration sensor, and belongs to the field of a human-computer interaction input interface of a computer. The multifunctional wearable human-computer interaction input equipment has various computer peripheral functions including a mouse, a handle, a wheel and the like. The accelerated velocity of an induction palm in X-axis and Y-axis directions by an MMA7361 acceleration sensor; then, an analog signal output by the acceleration sensor is processed and converted into motion state parameters including the inclination gesture, the rotation angle speed, the rotation acceleration and the like of the user palm; according to a function mode (the mouse, the handle, the four-direction wheel and a self-defined keyboard) selected by an operator, a corresponding control algorithm is dynamically called to carry out analysis processing on gesture movement so as to realize different input equipment functions. The multifunctional wearable human-computer interaction input equipment can be designed into various boundary dimensions convenient to wear, a sleep awakening function is designed in a program, and the multifunctional wearable human-computer interaction input equipment is especially suitable for occasions including meetings, classrooms, exhibition rooms and has the advantages of wide application prospect and important research value.

Description

technical field [0001] The invention belongs to the field of computer human-computer interaction input interface, and is characterized in that it has the control functions of various PC peripherals such as mouse, handle, four-way scroll wheel and self-defined keyboard, and provides users with a brand-new interaction mode. Background technique [0002] In recent years, the popularity of tablet mobile devices, three-dimensional browsers, and digital set-top boxes has made traditional mechanical, photoelectric, and laser mice unable to meet the needs of rapidly developing electronic products. The traditional mouse must rely on a relatively flat desktop to use it normally. The disadvantage is that it limits the scope of the user, and it will cause swelling of the hand joints or even "mouse hand" after prolonged use. People are more willing to leave the desktop and use hand gestures to interact with computers, tablets, navigators or other smart devices. Human hands can freely mo...

Problems solved by technology

However, the disadvantages of this design are obvious. Firstly, the function is relatively simple and difficult to expand. Secondly, the hardware design is complex and costly. Furthermore, the obtained information is sent by the wireless module and then the cursor is driven, and the jitter is large and difficult to control.
