In order to allow consumers to have a more intuitive experience, the human-machine interface technology has been continuously improved in recent years. It has rapidly progressed from the traditional mouse control to diversified methods such as touch, gestures, somatosensory, and voice control. However, the progress of interface technology is never-ending.
New applications for eye tracking and brainwave control have emerged on the market. The industry is trying to extend these medical technologies in the past to larger consumer markets. As the technology matures, it is expected to bring more innovations in the future. application. In the past, there have been examples of using eye tracking technology to control computer operations, but most of them are special devices designed for deaf patients, and there is no large number of commercial applications. Driven by the dual factors of technology maturity and price decline, the industry has been optimistic about expanding eye tracking technology to consumer applications such as computers, mobile phones, automobiles, and game consoles. The basic principle of eye tracking technology is to irradiate the user's eye with a low-power infrared beam. The sensor then captures the light reflected from the pupil, iris, and other parts of the eye. After a complex algorithm analysis, the eyeball can be determined. The goal of attention.
This technology has a long history of development. With the advancement of electronic technology, the expensive eye-tracking headset has dropped from 30,000 US dollars a decade ago to less than 15,000 US dollars. At the same time, fixed-eye control devices for computer control have already reached less than 5,000 US dollars, and Swedish company Tobii Technology expects such devices to drop below 3,000 US dollars in the near future, and related applications will also rise. Take Tobii, who has emerged in the past two years as an example. The company has released several products in succession. It can use eye tracking technology for the human-machine interface of computers and game consoles. Users can select, scroll, zoom, and navigate with their eyes. operating. In fact, optimistic about the prospects of eye tracking technology, Intel has invested 21 million US dollars last year to buy 10% of Tobii shares. Tobii also announced the latest Tobii REX and Tobii Gaze Partner projects that support Windows 8 earlier this year in an attempt to build an ecosystem partner to allow eye tracking applications to take off quickly in the short term.
Not only that, but Lenovo and Haier have all started developing laptops and smart TVs that use eye tracking technology. In addition, Samsung has recently launched a new mobile phone, the Galaxy S4, which can be used to eye-roll mobile phone pages. It can be expected that more and more consumer products will adopt this new human-machine interface technology in the future. Another Eye Tribe, who was independent from a university research institute in Copenhagen in 2011, is also actively developing a commercial eye-tracking software development kit for use by game developers. It has also received attention from toy makers LEGO and the Danish National Fund.
The brain-computer interface is another emerging human-machine interface. It has developed a biosensor that can detect brain waves and is used for various applications such as manipulating machines, training the brain, and educating and learning. As with eye tracking technology, the field of brainwave sensing has been confined to medical applications in the past. The main reason is that various noises in the external environment will affect the capture of brainwaves. Patients usually need to be on the head in a non-interference environment. Apply wet gel to detect brain waves. This situation was followed by a breakthrough in NeuroSky's development of the first dry brainwave sensor and patented noise filtering technology in 2008 and its use in toys that promote the ball's ability to promote the ball. NeuroSky, founded by Chinese ethnic group Yang Shichao, has received extensive attention from mainstream media in the past two years.
