Embodiment
The embodiment of the invention provides a kind of input method of terminal, and this terminal comprises a keyboard and image acquisition units, and described keyboard comprises at least one button.This input method judges that whether the distance of input body (as user's finger or input pen etc.) and keyboard upper surface is less than predetermined value, and judge whether described at least one button produces push button signalling, in described distance less than described predetermined value, and when not producing described push button signalling, gather the motion track of described input body at the upper surface of described keyboard, and then, generate input command according to described motion track.
Below with reference to accompanying drawing, the present invention is further illustrated by specific embodiment.In following examples, describe as described terminal with computing machine.
Please refer to Fig. 1, the input method of the described computing machine of present embodiment may further comprise the steps:
As shown in Figure 2, be example with the portable notebook computer, present embodiment is given directions input area with keyboard upper surface (dotted portion among the figure) as keyboard, and this zone is obviously greater than the touch pad of traditional notebook computer.Input body (can be user's finger or other input block, as writing pencil etc.) has multiple with the judgment mode of the distance of keyboard upper surface:
(1) light detection mode: whether the upper surface top of detecting described keyboard is blocked with the light signal of described upper surface distance less than described predetermined value; When detecting described light signal and be blocked, the distance of upper surface of judging described input body and described keyboard is less than described predetermined value.
This judgment mode specifically can adopt light detection mode shown in Figure 3 or camera detection mode shown in Figure 4.
Wherein, in the light detection mode shown in Figure 3, by in keyboard 21 both sides light source 22 and optical receiver 23 being set respectively, the parallel top through the keyboard upper surface of the light signal that this light source 22 sends finally arrives optical receiver 23.Certainly, light signal also can not be the parallel top through the keyboard upper surface, but presents certain included angle (angle is less) with the keyboard upper surface, arrives optical receiver 23 then.Like this, the distance of supposing light signal and keyboard upper surface is described predetermined value, when the distance of input body and keyboard upper surface during less than described predetermined value, light signal will be transfused to body and block, when optical receiver 23 can not receive light signal, can judge the distance of input body and keyboard upper surface this moment less than predetermined value; Otherwise,, judge that then the distance of input body and keyboard upper surface is greater than described predetermined value if when optical receiver 23 can receive light signal.
Wherein, in the camera detection mode shown in Figure 4, a camera 24 and the shutter 241 relative with camera 24 are set respectively in the both sides of keyboard 21, this camera 24 is taken the shutter 241 on opposite through the keyboard upper surface from the keyboard side.The principle that camera 24 is taken shutter 241 also is the light signal that receives shutter 241 reflections, therefore, suppose that the light signal of certain reflection and the distance of keyboard upper surface are described predetermined values, when the distance of input body and keyboard upper surface during less than described predetermined value, the light signal of this reflection will be transfused to body and block, camera 24 will receive the light signal of input body reflection, thereby can photograph the background image that includes this input body.So, the difference of the background image that photographs by judgement (initial background image when promptly not having the input body and the background image when the input body is arranged), whether the distance of judging input body and keyboard upper surface is less than predetermined value; Otherwise when this imported body away from the keyboard upper surface, this camera 24 can not photograph this input body, can only photograph the background image that only includes shutter 241 again.Therefore, can just can judge that whether the distance of importing body and keyboard upper surface is less than described predetermined value by setting the height of shutter and camera according to the photographic images of this camera.
(2) capacitance detecting mode: the electric quantity change that detects the conductive layer that is provided with on the described keyboard; When detecting described electric quantity change and satisfy predetermined condition, the distance of upper surface of judging described input body and described keyboard is less than described predetermined value.At this moment, can adopt capacitive transducer detection mode shown in Figure 5: on keyboard 21, arrange one deck conductive layer 25, when input body (as user finger) come in contact with the keyboard upper surface or near the time, with the weak current transmission that causes between human body and the conductive layer 25, thereby cause the electric quantity change (as the electric weight minimizing) of conductive layer 25; By detecting the electric quantity change that described input body causes, and then when whether described electric quantity change satisfied predetermined condition, the distance of judging input body and keyboard upper surface was less than described predetermined value.
Here, as shown in Figure 6, present embodiment is provided with a camera on computers, and (Fig. 6 is example with the portable notebook, computing machine for other type, principle is identical), this camera (circle among Fig. 6 is represented this camera) place keyboard the top (as directly over or the front upper place), can take whole keyboard upper surface.Here, the described input body of described collection at the motion track of the upper surface of described keyboard is, when importing body (as by finger) when the keyboard upper surface moves, camera is discerned the image that collects, obtain the position coordinates of input body, and then, calculate the motion track of described input body according to described position coordinates.
Input command described in the present embodiment specifically can be the cursor control command, in order to control cursor moving on the displaying contents of computing machine.The cursor control of this moment is similar with the input control of common notebook touch pad (touchpad): by importing the motion track of body at surface of keyboard, be mapped to the movement locus of cursor on computing machine demonstration desktop of mouse.For example, according to moving direction, speed and the distance of input body, correspondingly control cursor in the moving direction, speed and the distance that show on the desktop, and then realize giving directions operation by keyboard at surface of keyboard, to computing machine input cursor control command, in order to control the purpose that cursor moves.
Input command described in the present embodiment can also be a gesture command, for example, when the motion track of described input body on keyboard is the circle of a sealing, then generates a gesture command that is used for lock-screen; When the motion track of described input body on keyboard is " * " shape, then generate a gesture command that is used to close current window.
Present embodiment is in above-mentioned flow process, terminal has the keyboard input pattern simultaneously and keyboard is given directions input pattern, distance between the upper surface that satisfies input body and described keyboard is less than described predetermined value, and when not producing the condition of described push button signalling, terminal is given directions input pattern work according to keyboard, according to described motion track, generate input command.If in above-mentioned flow process, the input body is by any button on the lower keyboard and produced the corresponding key signal, and then terminal will receive and handle above-mentioned push button signalling according to normal keyboard input pattern work.
In the present embodiment, when terminal is given directions input, just open image acquisition units (as camera); And when computing machine carries out the button input, close the detection system of camera and touch keyboard, to save power consumption of terminal.Certainly, if do not consider the problem of power consumption, image acquisition units also can be worked always, and only terminal is not carried out the conversion of motion track and input command when not giving directions input.
Present embodiment can also pass through the physical switch mode, comes control terminal to switch between keyboard input pattern and keyboard indication input pattern, makes terminal only be operated under wherein a kind of pattern at synchronization.At this moment, present embodiment also comprised before above-mentioned steps 11:
Step 10 receives one and is used to indicate the control signal that enters described keyboard indication input pattern; According to described control signal, control described terminal and enter described keyboard indication input pattern.
Here, above-mentioned control signal is imported by physical switch.Physical switch can be manual extra toggle switch or keyswitch, by stir or press to different directions/by going out switch, control terminal enters different keyboard input patterns.Physical switch can also adopt and be similar in the above-mentioned steps 11 the light detection mode that distance adopted or the capacitance detecting mode that detect input body and keyboard upper surface and realize: please refer to Figure 10 and shown in Figure 11, two palmrest zones 31 that set in advance on the terminal, 32 (the keyboard belows that these two palmrest zones are arranged on, being about to two palmrest zones is arranged on the main frame between keyboard and the user), judge the distance in first contact 33 and the first palmrest zone 31, and whether the distance in second contact 34 and the second palmrest zone 32 is all less than predetermined threshold value (two contacts can be two palm/wrists of user); Less than the distance in predetermined threshold value and second contact 34 and the second palmrest zone 32 during also less than predetermined threshold value, automatic switchover keyboard input pattern is the keyboard input pattern in the distance in first contact 33 and the first palmrest zone 31; During less than predetermined threshold value, automatic switchover keyboard input pattern is that keyboard is given directions input pattern in the distance of having only a contact (contact 33 or contact 34) and a palmrest zone.Like this, when user's two hands are placed on two palmrests zone on the keyboard respectively, terminal will enter the keyboard input pattern; As user when only hand is placed on palmrest zone on the keyboard, terminal will enter keyboard and give directions input pattern.The contact here is different with aforesaid input body, contact by with whether the contacting of palmrest zone, supervisory keyboard button input pattern, this contact can be a user's wrist in the practical application; Whether aforesaid input body contacts with the keyboard upper surface, is the controlled condition that track is gathered, and the input body is generally user's finger or input pen etc. in the practical application.
In the present embodiment, after computing machine enters keyboard indication input pattern, open image acquisition units (as camera); After computing machine withdraws from keyboard indication input pattern, close the detection system (perhaps only closing one of them) of camera and touch keyboard, to save equipment power dissipation.Certainly, if do not consider the problem of power consumption, image acquisition units also can be worked always, and only terminal is not carried out the conversion of motion track and input command when not giving directions input.
By physical switch, control terminal enters keyboard give directions input pattern after, present embodiment can also receive button on the keyboard push button signalling that the back produces that is pressed, and according to described push button signalling, carries out corresponding operation.
Concrete, as a kind of embodiment, can receive any button on keyboard push button signalling that the back produces that is pressed in the present embodiment, and after receiving described push button signalling, carry out the left mouse button operation in the cursor current position.Left mouse button operation comprises that left button clicks and the left button double click operation, for example, receives only once described push button signalling in the given time, then carries out the left mouse button single-click operation; If receive described push button signalling in the given time twice, then carry out the left mouse button double click operation.Here, if continue to receive described push button signalling, then can also carry out the mouse drag operation according to described push button signalling, that is, the object at described cursor position place pulls when initially receiving described push button signalling.
As another kind of embodiment, present embodiment can set in advance (or a class) button corresponding to left mouse button, another (or another kind of) button is set corresponding to right mouse button.Like this, behind the push button signalling that receives described one (or a class) button generation, carry out the left mouse button operation in the cursor current position; Behind the push button signalling that receives described another (or another kind of) button generation, carry out the right mouse button operation in the cursor current position.Same, left mouse button operation here comprises that also left button is clicked, double click operation, the right mouse button operation also comprises right-click, double click operation.If continue to receive the push button signalling that described one (or a class) button produces, then can also carry out the mouse drag operation according to the push button signalling that described one (or a class) button produces.
From the above as can be seen, present embodiment has the following advantages:
1) owing to adopt the keyboard upper surface to give directions the zone of importing as keyboard, with respect to the touch pad input of traditional portable notebook, the keyboard upper surface of present embodiment can provide bigger input area, therefore can be convenient for user input operations.
2) with respect to only adopting the camera collection motion track, and then the mode that moves of control cursor, present embodiment can provide the accuracy of input, and can avoid importing the problem of maloperation, its reason is: prior art is only imported the motion track of body by camera collection, for example when the user thinks that mouse beacon moves to right, the input body can be moved right, to attempt to import a track that moves right.Because user action has the characteristics of " back and forth " usually, after will importing body and moving right, can habitually turn back to initial position again usually with importing body.In this case, camera can't determine when and begin to gather and when stop to gather motion track, thus camera collection to may be a reciprocal motion track, the track of wanting to import with the user that moves right does not conform to.And in the present embodiment, the user will import body near to or in contact with the keyboard upper surface and do not produce push button signalling when wanting to carry out keyboard and give directions input, will trigger the collection of motion track at this moment; When the user wants to stop to import, will import body away from the keyboard upper surface, can trigger and stop the motion track collection, thereby make the track that collects meet user's expection, reduced the problem of input maloperation.
Further, the described terminal of present embodiment can also comprise a display unit, and the mode that described input method can also further show by stack is added the image of importing body in the display image to.Fig. 7 shows a kind of application scenarios of above-mentioned stack display process, when the user operates on the keyboard upper surface by hand, can see comprising that user's hand is directly to the image of the control of Action Target on display unit.At this moment, the described input method of present embodiment when gathering the motion track of described input body at the upper surface of keyboard, also comprises:
Here, can pass through image acquisition units 71, gather the image that comprises described input body (as the user's hand 72 among Fig. 7), locate the position of described input body, analyze the motion of described input body.Also can be, and when not producing described push button signalling in the distance between the upper surface of input body and keyboard less than described predetermined value, just begin to control image acquisition units 71 and go to gather and comprise first image of importing body.
When 71 pairs of inputs of image acquisition units body carries out image acquisition, also comprise background image except described input is external in the image that collects, as keyboard image.The image that present embodiment can directly collect image acquisition units 71 is as described first image; Also can further handle the image that image acquisition units 71 collects, filtering background image wherein only keeps the image of described input body, as described first image.
Step 22 is added described first image in the original displayed image of described display unit to.
Here, described original displayed image can be the true picture on the desktop, as shortcut icon on the desktop or window, can also be the virtual content that terminal produces, and uses for user's operation and observes, as treat picture that the user operates etc.
Here, when adding to the image of described input body in the described original displayed image, can also be according to the motion of described input body, controlling described original displayed image changes accordingly, for example, according to the motion track of input body, by the position of pulling mode change original displayed image, and the size of change original displayed image etc.Again for example, image acquisition units collects the input body and has drawn one " * " at the keyboard upper surface, to synchronously show the image of this input body at display unit this moment, and this input body is drawn " * " on current window action shows, and then, current window is closed according to the current window shutdown command that " * " generates correspondence.Further, motion track stack itself can also be presented on the original displayed image, show that promptly " * " in window, finishes input up to the user.
