Computer standard peripheral mouse and keyboard technology is relatively mature, but its operation is monotonous, and the technology has not made breakthroughs for many years; the technology of touch screen has recently appeared, and soon became a hot spot, this technology requires special display touch device, In addition to the input requirements; in addition, the above two input methods are limited by the principle of the input device, inevitably constraining the user around the display device and the input device. In this industry context, there is a need for a humanized smart wireless input device to meet the increasingly popular multimedia presentation, office and personal computer applications.
Under this premise, the team developed a gesture input system called Smartmouse, which allows the user to easily attach the handheld end of the device to the hand and connect the host to the PC via the USB interface. Control the PC. Gestures can be used to complete all the functions of the mouse, while also allowing smooth operation of today's popular everyday applications. The biggest difference between Smartmouse's operation and touch screen and traditional mouse is that it can get rid of the dependence on the screen and fixed input device, so that it can better adapt to today's multimedia environment. Enable computer users to break away from the limitations of traditional mouse and keyboard, and establish a more user-friendly way of communication between users and computer devices.
At present, domestic input equipment manufacturers have improved on existing input devices, such as Xingui, Shuangfeiyan and other companies, the introduction of multimedia mouse, keyboard, on the basic functions of the original keyboard or mouse, add shortcut keys to multimedia software . Although such products increase the user's ease of use, most of them are expensive, and more importantly, there is no qualitative change in their input methods.
Huazhong University of Science and Technology recently developed a human body upper limb motion input device based on spatial motion measurement technology. The input mode of the device adopts the human body bionic design and has a breakthrough. However, the system has many hardwares, complex recognition algorithms, and a promising industrialization prospect.
The same foreign products as early as 2001, Samsung and SenseBoard showed the virtual keyboard under development, Samsung's product development stage is called "Scurry". The products of the two companies differ in the way they are identified, but they all bring revolutionary changes that can abandon the traditional mouse and keyboard. The problem with this type of input device is that the user still has to mimic the action of keyboard tapping while in use.
By the end of 2004, the development of this kind of keyboard is still in the stage of wired connection. Until now, there has been no news of the official listing of "Scurry" because the equipment is expensive, expensive, and difficult to commercialize.
The Wii, produced by Nitendo, is similar to the one that uses perceptual acceleration to manipulate the game, but it can only be used as a gaming device and uses infrared transmission, which is limited by angle and distance.
In the 1970s and 1980s, a lot of research on data gloves was carried out in the world to capture the movements of the hands, but the research was stagnant soon after. At present, the popular practice of gesture recognition is to adopt a method based on visual image recognition. The camera captures the motion image and uses the image processing method to obtain the motion information. However, this gesture recognition method is expensive, and the requirements for hardware and software are also very high. It cannot be used as an input device for a normal PC at all.
With the rapid development of MEMS technology and ultra-low-power wireless communication technology, the development of ultra-small-volume, ultra-low-power MEMS accelerometers and wireless communication modules has designed us to develop a broad application prospect and more humane. Convenient and fast input devices provide protection.
1.3 The advancement of this designSmartmouse smart gesture input device is not only limited to computer input, but also can be used in many fields such as multimedia device control, and has a very wide range of applications. Moreover, there are no input devices on the market that use acceleration sensors and incorporate technologies such as wireless communication and USB plug-and-play. The emergence of Smartmouse smart gesture input devices will attract a group of high-end users who are pursuing new things.
As a product, Smartmouse intelligent gesture input device not only has the advantages of existing products, but also overcomes the shortcomings of existing products; it combines humanization, ease of use and portability, and provides users with a new operating concept. Will gain the favor of the market.
