Description
The present invention relates to a kind of man-computer interface message exchange and control system.
After introducing mouse, people have developed figure control interface on this basis, comprise in the computer industry that snafu change has all taken place from the idea to the skill in the software development of operating system.It is practical and popular that computing machine becomes at this point.Certainly, mouse in use also has some inconvenient aspects.For the operation that makes computing machine adapts to layman's use, people have developed the technology of clipboard handwriting input on the technical foundation of computing machine coordinate identification.Under certain situation (for example the literal input is handled), people's both hands need concentrate on the keyboard, and mouse needs people's an other hand.Certainly in fact people do not have so pickpocket, so mouse makes people feel in a rush sometimes, at this moment, mouse is an outer parcel received of computing machine seemingly.98119326.9 97120301.6,97119205.7 have proposed to improve the scheme that mouse has proposed.Utility model patent 98205967.1 has proposed the thinking with the mouse of foot control system.Certainly, in the time of computed, because pin not within people's range of vision, seems that some complexity, people need to run sometimes so operate, this gives with pin operation mouse and makes troubles.Some patents are as 95195866.6 methods that also proposed with the inducing method realization graphic operation of touch screen, and but, this still can not liberate both hands.Also the someone proposes to utilize the method for sound (98114665.1) input, but voice recognition not only needs to take many system resource, and speed is slow, up to the present, goes back incompatibility figure man-machine interface.
The present invention proposes the activity of a kind of computer operator's of using head and controls moving of cursor, and the system that the air-flow that utilizes computer operator's oral area to blow out instructs to computer input operation, thereby can free computer operator's both hands, return to keyboard and other operations.This system is called the port mark system that is used for man-computer interface.
The port mark system that is used for man-computer interface comprises electromagnetic beam coordinate signal transmitting element (2b), air-flow instruction determining unit (2a) and electromagnetic beam coordinate signal receiving element (4) and (5).Wherein electromagnetic beam coordinate transmitting system be fixed on the computer operation user of service head (certainly, also can just be fixed on computer operation user of service's oral area), it is oral area with personnel that air-flow instruction determining unit is fixed on computer operation, and electromagnetic beam coordinate receiving element (4) and (5) are fixed on the edge of graphoscope (3) screen.
The electromagnetic beam coordinate signal that electromagnetic beam coordinate signal transmitting element (2) sends on vertical plane be projected as orthogonal two slices (2ba) with (2bb), act on the horizontal receiving element of orthogonal electromagnetic beam coordinate signal (4) and vertical receiving element (5) respectively.Electromagnetic beam (2ba) and position (2bb) and the position and mobile decision of moving by computer operator's head.
When horizontal receiving element of electromagnetic beam coordinate signal (4) and vertical receiving element (5) receive respectively electromagnetic wave pencil (2ba) with (2bb) after, can be according to the position of electromagnetic beam on two receiving elements, read its position coordinate value X and Y respectively, just can obtain electromagnetic wave pencil (2ba) and (2bb) indicated coordinate (X after synthetic, Y), and by suitable circuit feed computing machine (10).If (X Y), and calculates, compares the test constantly coordinate, and computing machine (10) then can obtain the electromagnetic wave pencil coordinate difference (Δ X, Δ Y) between current time and the previous moment.
The electromagnetic wave pencil (2ba) that electromagnetic beam coordinate transmitting element sends and length (2bb) should with the length coupling of electromagnetic beam coordinate receiving element (4) with (5), make receiving system (4) and (5) (2ba) with (2bb) in whole sweep interval, can receive electromagnetic position signalling.For fear of the phase mutual interference of signal, (2ba) with (2bb) signal difference to some extent.A kind of mode is to adopt the electromagnetic wave signal of different frequency (wavelength).For the electromagnetic wave signal of identical wavelength, can adopt being modulated of different frequency to it.Electromagnetic wave pencil positioning signal transmitting element is made up of electromagnetic wave wave source (2a1) and imaging system (2a2).
Electromagnetic beam coordinate signal transmitting element (2b) should be fixed on computer operation user of service's head, both can instruct determining unit (2a) to integrate with air-flow, also can be arranged in other places of head, for example is arranged in the crown as miner's lamp.But, air-flow instruction determining unit (2a) must be arranged in computer operation user of service's oral area, with the stream operated computing machine that utilizes its oral area to blow out.
Air-flow command reception unit (2a) should be divided into several independently pneumatic sensors.Generally speaking, air-flow command reception unit (2a) is divided into several (for example three) standalone sensors (2a1), (2a2) with (2a3).Middle one be air-flow master reference (2a2), both sides be respectively secondary air sensor (2a1) and (2a3).
The pneumatic sensor unit can be divided into two classes, and a kind of is the speed mode sensor, and another kind is a pressure type sensor.
In the speed mode pneumatic sensor, impeller shaft (2c) connects impeller (1c), damping fin (1d) and measurement sheet (1e), and be installed on two impeller shaft bearings (3c).One side of impeller (1c) is by air flue (4c), and when air communication was crossed air flue (4c), impeller (1c) will rotate, and impeller shaft (2c) drives damping fin (1d) with measuring sheet (1e) rotation.
When measuring sheet (1e) rotation, by measuring-signal source (2e), measuring-signal receiver (3e) and measuring-signal receive line (4e) can measure the rotating speed of impeller (1c) with measuring-signal power lead (5e), thereby calculates the speed of air-flow in the air flue (4c).The signal that measuring-signal receiver (3e) collects can directly be sent into computing machine (10), distribute certain system resource that the signal of gathering is handled by computing machine, also can design the signal that an independent operational order recognition subsystem collects measuring-signal receiver (3e) and carry out sending into computing machine (10) again as operation instruction signal after the rough handling.
Damping fin (1d) is a rosette, if feed electric current at coil (3d), then produces magnetic field and stops damping fin (1d) to rotate.
After proper circuit and software were connected, speed mode stream operated sensor unit basic operation process was as follows: when air communication was crossed air flue (4c), impeller (1c) rotated, and when its speed reaches rated speed, we are referred to as to click and start rotation speed n
1After, send the signal that starts one click to computing machine or operational order recognition subsystem, connect related circuit simultaneously, feeding electric current in damping coil (3d) is to impeller (1c) damping, when its rotating speed is reduced to a desired speed (n for example
1/ 2), we are referred to as to click and finish rotation speed n
2After, send the signal that one click is finished to computing machine, simultaneously, cut off the electric current in the damping coil (3d).System enters the readiness that reception is clicked next time.
After one click starts, continue in air flue (4c), to blow, make the rotating speed of impeller (1c) maintain click startup rotation speed n
1Finish rotation speed n with click
2Between the speed, people can arrange the screen object drag operation.In actual applications, the impeller (1c) of the velocity profile sensor of air-flow, damping fin (1d) can be integrated with measurement sheet (1e) three, and perhaps wherein both merge.
In pressure type stream operated sensor unit, after feeding air-flow in the air flue (4f), blade (1f) motion promotes moving contact (2g) motion, disconnects normally closed fixed contact (1g), connects and often opens fixed contact (3g).After gas velocity reduced, under the effect of back-moving spring (1h), moving contact (2g) recovers normally closed fixed contact (1g) to be connected, and disconnects simultaneously and often opens fixed contact (3g).
If adopt pressure type stream operated sensor unit as the main operation unit, the onscreen cursor position in the man-machine interface (x, y) should direct corresponding electromagnetic wave pencil (2ba) with (2bb) indicated coordinate (X, Y).This design advantage is easy and simple to handle directly perceived, shortcoming be people's neck movement amount more greatly scanning whole screen, and require thinner some the smaller figure buttons of alignment of showing of motion, these obviously are unfavorable for manipulating of computing machine.
Adopt speed mode stream operated sensor unit as the main operation unit, be lower than and click the startup rotation speed n
1Impeller (1c) rotation speed n can be used as control cursor moving speed controlling elements.For example we can with the onscreen cursor current location in the man-machine interface (x y) is expressed as:
x＝x
1+Δx
(1)
y＝y
1+Δy
(2)
(x
1, y
1) be the previous moment position of cursor.(Δ x, Δ y) is the coordinate difference of the cursor position of current time and previous moment.By one and airstream velocity sensor function, make these differences and electromagnetic wave pencil (2ba) relevant with (2bb) indicated coordinate difference (Δ X, Δ Y):
Δx＝αf(n)ΔX
(3)
Δy＝αf(n)ΔY
(4)
F in the formula (n) is the function of an impeller (1c) rotation speed n, and α is a scale-up factor.If we get:
f(n)＝1/(β+n
2)
(5) according to above funtcional relationship, air-flow is fast more, and impeller (1c) rotation speed n is high more, and cursor moving speed is slow more, and promptly under identical electromagnetic wave pencil coordinate difference (Δ X, Δ Y), cursor difference (Δ x, Δ y) raises along with wheel speed n and reduces.
We get other funtcional relationships, just have different corresponding relations between (Δ x, Δ y) and (Δ X, Δ Y).
The left click that if the primary air sensor utilizes the positive air flow of computer operator's oral area to finish is equivalent to mouse operation, so, utilize secondary air sensor of side stream operated of computer operator's oral area promptly can finish the right click operation that is equivalent to mouse.Because people can blow out the side air-flow at several different directions up and down, can arrange a plurality of secondary air sensors, finish the necessary operation of some port mark systems, as adjust cursor coordinates (x, y) with electromagnetic beam coordinate (X, Y) operation of difference the time, can also increase some new operating functions.

With Fig. 1 is example, and electromagnetic beam coordinate receiving element (4) can be indicated position (X, light activated switch Y) separately with vertical receiving element (5) to computing machine for a series of.
Air-flow instruction sensor (2a) should be divided into 3 independently sensor units, (2a1), (2a2) with (2a3), wherein utilizing the sensor (2a2) of the air-flow that computer operator's oral area front blows out is speed mode stream operated sensor, as the primary air sensor.The tachometric survey mode of primary air sensor is to beat several holes equably at measurement sheet (1e), installation light source in measuring-signal source (2e), installation photelectric receiver in measuring-signal receiver (3e).
(2a1) with (2a3) be the pressure type pneumatic sensor.Electromagnetic beam coordinate transmitting element (2b), wherein electromagnetic wave pencil positioning signal transmitting system is fixed on computing machine behaviour with near personnel's the oral area.
Because being speed mode stream operated sensor, the primary air sensor does, so (x, y) (X Y) determines that by aforementioned (5) we get with the indicated coordinate of electromagnetic wave pencil in the onscreen cursor position
α＝(3/14)n
1 2
(6)
β＝(1/14)n
1 2
(7)
In the formula n
1Start for clicking rotating speed, we can obtain, and when gas velocity is zero, impeller (1c) rotation speed n also is zero, at this moment,
αf(0)＝3
(8)
Promptly when gas velocity was zero, cursor difference (Δ x, Δ y) was 3 times of electromagnetic wave pencil coordinate difference (Δ X, Δ Y).Be convenient to people under the little prerequisite of headwork, significantly the moving cursor position.
When reaching cursor, impeller (1c) rotation speed n clicks the startup rotation speed n
1The time,
αf(0)＝1/2
(9)
At this moment, cursor difference (Δ x, Δ y) be electromagnetic wave pencil coordinate difference (Δ X, Δ Y) (1/5) doubly, the computer operator can suitably blow and reduce the translational speed of cursor, so that alignment button and clicking.
The stream operated that pressure type pneumatic sensor (2a3) utilizes the right survey of computer operator's oral area top blast to go out is finished the operation of similar mouse right click.
