Description
Technical field
The present invention relates to man-machine interaction input technology, more particularly to a kind of hand to touch interactive system.
Background technology
Touch screen technology is a kind of new man-machine interaction input mode, with traditional keyboard and mouse input mode phase
Than touch-screen input is more directly perceived.Perfect with touch screen technology, due to the convenience of manipulation, touch-screen is gradually in many
Occasion instead of mouse and keyboard.Touch-screen is mainly made up of touch detection part and touch screen controller, touch detection part
Before indicator screen, for detecting touch location, relevant information is then sent to touch screen controller.Touch-screen control
The main function of device processed is to receive touch information from touch point detection device, and is converted into contact coordinate and sends CPU to, together
When receive the instructions sent of CPU and performed.Coordinate identification software, the functions such as handwriting input can also be realized by touch-screen,
Touch-screen develops into multipoint touch screen by initial single-point touch screen at present.
Although touch-screen has more advantages than keyboard and mouse, because three characteristics of touch-screen cause it
With it is following the shortcomings that：
It is first, transparent.As the first characteristic of touch-screen, transparency directly affects the visual effect of touch-screen.It is many to touch
Touch screen for multilayer laminated film, only with this transparent feature come summarize its visual effect be it is inadequate, at least should include four
Individual characteristic：Transparency, color distortion degree, reflective and definition.Due to the presence of translucency and wavelength curve figure, pass through touch
Shield the image seen and color distortion is inevitably produced compared with original image.When being observed through touch-screen, static image
Feel to be color distortion, dynamic multi-media image can then produce certain obscure.Reflective is referred mainly to due to mirror-reflection
Cause it is overlapping on image after shadow, such as shadow, window, light.The strong touch-screen use environment of reflective receives greatly
Limitation.The touch-screen reflective handled by frosted is decreased obviously, but its transparency and definition are also greatly lowered.Install additional
The definition brought after touch-screen declines the fatigue for easily causing eyes, and long-term use easily causes the injury of eyes.
Second, absolute coordinate system.Touch-screen uses absolute coordinate system, to select where just point where.It is this kind of with mouse
The essential distinction of relative coordinate system is that the elements of a fix and the last elements of a fix are not related each time for absolute coordinate system.This
No matter when requiring touch-screen, the output data of same point should be consistent and stablize.If unstable, that
Touch-screen cannot ensure that absolute coordinate positions, i.e., contact drifts about.With the development of technology, large-sized FPD is increasingly
Prevalence, it will become apparent from using the touch-screen problem encountered of absolute coordinate system, screen has much, to be touched needed for it faces
Product just have it is much, in order to touch relevant position, it is also necessary to human hand carry out more at a distance motion, when screen area increases to one
After determining degree, then touch-screen caused convenience in itself is lost.
Third, detection is touched and positioned.Various touch screen technologies are all to carry out work by respective sensor, or even are touched
Touch the inherently a set of sensor of screen.Respective positioning principle and sensor used determine touch-screen reaction speed, can
By property, stability and life-span.
It is relatively low using the touch-screen price of infrared technique from current touch-screen present situation, but its housing rapid wear, easily production
The third contact of a total solar or lunar eclipse disturbs, easy distortion in the case of curved surface；Using the touch screen design reasonable idea of capacitance technology, but scheme after using composite membrane
Image distortion problem hardly results in basic solution；Using the touch-screen accurate positioning of resistive technologies, but it is on the high side, and be afraid of to scrape easily
Damage；And use the touch-screen definition of surface acoustic wave technique good, but screen surface can then cause if water droplet and dust etc.
Touch blunt or even touch failure.With the prevalence of large-sized FPD screen, touch-screen can technically face bigger choose
War.
And use the man-machine interaction input technology of other technologies.Such as：
1）The Kinnect of Microsoft, it is integrated with the functions such as dynamic immediately is caught, image identifies, change makes in the past
Function is supported with the single mode of operation such as keyboard, mouse, handle, and with hard recognition and gesture, but Kinnect is as trip
Play peripheral hardware, its accuracy of identification is relatively low, response speed is slower, is caught based on dynamic, the hand interactive mode of image recognition technology is held
Easily influenceed by external environment, poor reliability, the application scenario high to real-time, reliability requirement can not be adapted to.
2）The Leap Motion hand interactive controlling technologies of Leap companies, compared to Kinnect technologies, having can be quick
And the characteristics of identifying hand position and the motion of user exactly, but because Leap Motion use infrared LED+bis- shootings
The technology of head, the hand of user necessarily be in identification field, blocked beyond identification critical zone or Toe Transplantation for Segmental Finger by other fingers
In the case of, system then None- identified.Cog region is too small to limit its application, and cog region it is excessive then it is difficult to ensure that precision and
Anti-interference, it can not equally be applied to the high occasion of reliability requirement.
3）The MYO wristband arts of Thalmic Labs companies, belong to a control terminal device, its general principle is profit
The biological Electrical change caused by the inductor seizure user arm muscles motion on arm bag, judge the intention of wearer, then will
The result of computer processing is sent to controlled plant by bluetooth.MYO uses internal detection, and advantage is not limited by use occasion
System, interaction more naturally, but its accuracy of identification and gesture enrich the limitation that degree is similarly subjected to use condition.
At present, domestic hand interactive system is still in the development stage, is transported mostly using with camera similar Kinnect
Dynamic capturing technology.Because the difficulty of hand interaction technique is high, it is difficult to ensure reliable precision and response speed, in the market there is no can
The hand interactive system product leaned on.
