As the fiery and intelligent manufacturing artificial intelligence, directly to the machine vision industry is also picking up. The current human-computer interaction technology has gradually shifted from computer-centric to user-centric, and gesture recognition technology allows users to interact with the computer or other intelligent terminal on the premise that no additional tools. In recent years, the rise of VR / AR technology, gesture recognition technology has become more important, more urgent market demand. The engineering practice to be achieved by the data acquisition computer binocular camera, a frame image based on computer vision and OpenCV preprocessing means, and further the gesture recognition system to develop a machine learning method. Preliminary simulation mouse and keyboard to achieve the purpose of interacting with a computer. The topics I will combine research and analysis software engineering practices gesture recognition area.
We experienced a "keyboard" interactive computer and to "touch screen" to "Voice gesture" of the development process. Gesture interaction means: the use of computer graphics technology to identify human body language and the like, and converted to a command to operate the device. AC gesture as a new way to interact booming, has natural advantages of convenience, it will constantly integrated into our daily lives. Microsoft, Leap Motion, Hand CV is the industry pioneer in interactive areas gesture, they rely on cameras, sensors and other hardware technology, computer vision, depth learning software technology will gesture recognition applications to the gaming device, VR equipment, automotive equipment and smart home scenarios in. The following are three gesture interaction product introduction.
1, Microsoft Kinect somatosensory equipment
Kinect is Microsoft in June 14, 2010 for XBOX360 somatosensory peripherals surrounding the official release of the name. Along with the name of the official release, Kinect also introduced a number of supporting games, including Lucasarts produced the "Star Wars", MTV launched the sports game "Kinect Sports", adventure game "Kinect Adventure", racing game "Joyride" and so on. Kinect does not require any controller, it relies on camera captures the player's movements in three-dimensional space, identification data depth and intensity data through special sensors, to bring players an unprecedented interactive experience.
2、 Leap Motion
Leap Motion is for PC and Mac somatosensory controller manufacturing company Leap on February 27, 2013 release of somatosensory controller, then on May 19 to buy exclusive sale in the US retailer Best, and on August 30, 2014 officially landing in China. Leap Motion sensor by tracing a finger, swipe your finger to browse the Web, read the article, look at photos and so on.
3、Hand CV
Hand CV is the Beijing Science and Technology Meggie British independent research and development of monocular interactive gesture recognition system. Hand CV is a monocular camera based gesture recognition systems and interactive SDK, which allows users to achieve gesture control under the premise of not to buy any peripherals. Hand CV biggest feature is based on monocular vision, so their SDK can support mobile phones and other mobile devices.
I took two of three from the aspects of this software research.
- These software developers is how to convince you (street ⽣ Face) become Using their households? Their destination time standard are profitable it? Their destination time standard is now ⾦ Use households earn it? Or something else?
I use Microsoft Kinect somatosensory equipment was done when students innovation and entrepreneurship, made a Kinect-based system of elderly care system. Other gesture recognition software is not used. These software are in addition to Hand CV appear in the form of commodities, profit target, consuming high commercial products. Hand CV is completely free of charge, at present we do not achieve universal access to VR, everyone wore head out of the scene does not appear significant. And dominates our lives is the most important smart phone technology, for mobile phone users, only a download APP can achieve this level of God operation, and then simply affordable enough. Therefore, the development inadvertently meet the needs of all. Hand CV is the world's only open single camera gesture recognition SDK, which is not only robust, there is a high recognition accuracy, which for VR / AR application development is simply the Gospel. Hand CV in traditional industries, whether medical or industrial, have its uses are the same.
- How is your software of your watch ⾥ (mail order, download, copy each other ⻉, online use ......)
Microsoft Kinect somatosensory equipment is provided by the instructor.
- The software has a Bug Why? A separate warranty is how to update the new version?
I did not find in the course. As for the updated version, which is not tested out or there are deficiencies in the conduct patch repair, and then release a new version, depending on the software version number to understand the extent of software updates for the previous version. Software products are generally maintained a relatively constant interface, so that the software proprietary to achieve change increased the user's operation remains unchanged will change very little. Interface is visible to the user is a public, non-public part of internal implementation software vendors for some known bug fixes, the new version will be launched before the implementation details hidden.
- Such software is when to start appearing, between ⼀ same type of software is how to compete? How trends?
Kinect was first unveiled at the 2009 E3, and officially released in the 2010 E3. 2016 British Meggie Technologies officially launched HandCV interactive gesture recognition systems, and gesture recognition SDK, open to all hardware and software application developers. Leap Motion is for PC and Mac somatosensory controller manufacturing company Leap on February 27, 2013 release of somatosensory controller, officially listed on May 13.
Between similar software rely on different features to attract users, users generally will consider whether charges function is strong, whether to facilitate the development.
Based on the judgment of the market, HandCV interactive gesture recognition system based on single camera (phone, tablet, PC, etc.), gesture recognition is achieved through software algorithms. Locating the mobile VR art, which use high robustness and good solution properties of simple user base gesture operation, such as determining, click, drag gesture and other basic interaction. So that more natural interaction, efficient and convenient. The market is different from most vendors such as LeapMotion, usens inspired by science and technology, is committed to the depth of gesture recognition problem that requires custom hardware and software adapted to meet the needs of complex interactions, HandCV other peripherals you do not need to complete between man and machine gesture interaction. Interaction is the bottleneck of content creation, while the Hand CV introduction is in order to solve these problems, this product will become the future mobile AR / VR content creation tipping point.
As a veteran of action in 2010 set up tracking technology companies, Leap Motion early in the project crowdfunding to get a lot of attention. Leap Motion can be considered a leader in the industry, gesture recognition in this area, Leap Motion binocular camera finished much attention in the industry, not only three-dimensional imaging, and for a variety of system version of the PC, you can achieve accessibility for everyday use, painting , games and more features, but the biggest problem at present is still too expensive.
Kinect creator Alex Kipman in an interview that they will still continue to have to provide support for Kinect users now, but the current development tools outlook is not clear, now Microsoft Kinect is no longer produced, while the products will also be after the sale of the retailer's stock to make a formal leave the stage. Kinect is a far-reaching impact of the product, and now it has been officially discontinued. Technology author Mark Wilson believes that although the product is dead, but the impact of Kinect remain, the core technology will continue to survive, used by other products.
- When you observe the list Using such software to "special" phenomenon, they and hardware What is the difference? These can explain some of the essential characteristics of the software it?
And compared to hardware, software is different from real life entities really exist, can touch. Software work better user experience, the structure nor the underlying hardware so complicated. Software is virtual, computer hardware is to configure some look to see, such as a keyboard, CUP, mouse, etc., but the software is invisible, but both are inseparable from each other. Software updates faster, the speed is much greater than the hardware.
- Your Face First Time Using such software is when you are at that time to get accustomed grade teacher called what? Where ⾥, what state, when the software is how to get (buy genuine, piracy, download?)
The first was a sophomore contest the use of guide members called white living treasure. Is the need to use it during the game. Teachers purchase offer.
- How you are proficient in this kind of software? It gives you any good, bad?
Is in the process of using the continuous use of it familiar, the advantage is a great experience, the downside is not portable.
- Using it you now what, or different brands of similar software, why?
Not in use, because there is no money, there is no learning opportunities related use.
- This software is another 10 or 20 years it will continue to exist, and why
There will be, human-computer interaction across the touch screen in the direction of non-contact gesture recognition march of development, the very image and have the action of gestures will be more relevant to people's lives. With the development of science and technology continues to mature, gesture recognition interaction science fiction movie realized just around the corner. Associated equipment and gesture recognition based on common monocular camera will be more fire in the future. With the warming of AR / VR market, gesture interaction experience will usher in peak demand.
