Embodiment
The embodiment of the present 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 whether input body (as user's finger or input pen etc.) and the distance of keyboard upper surface are less than predetermined value, and whether described at least one button of judgement produces push button signalling, be less than described predetermined value in described distance, and while not producing described push button signalling, gather the motion track of described input body at the upper surface of described keyboard, and then according to described motion track, generate input command.
Below with reference to accompanying drawing, by specific embodiment, the present invention is further illustrated.In following examples, describe as described terminal using computing machine.
Please refer to Fig. 1, the input method of computing machine described in the present embodiment, comprises the following steps:
Step 11, judges whether the distance between input body and the upper surface of described keyboard is less than predetermined value, and whether button on described keyboard produces push button signalling.Here, the distance of input body and keyboard upper surface is less than predetermined value, refer to that input body has occurred to contact with keyboard upper surface, although but not by the button on lower keyboard or supress button, but just supress a part, do not come in contact although do not produce push button signalling or input body and keyboard upper surface, distance is between the two very little.
As shown in Figure 2, taking portable notebook computer as example, the present embodiment is given directions input area using keyboard upper surface (dotted portion in figure) as keyboard, and this region 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 that described upper surface distance is less than described predetermined value; In the time detecting that described light signal is blocked, judge that the distance of the upper surface of described input body and described keyboard is less than described predetermined value.
This judgment mode specifically can adopt the camera detection mode shown in the light detection mode shown in Fig. 3 or Fig. 4.
Wherein, in the light detection mode shown in Fig. 3, by light source 22 and optical receiver 23 being set respectively in keyboard 21 both sides, the parallel top through keyboard upper surface of light signal that this light source 22 sends, finally arrives optical receiver 23.Certainly, light signal can not be also the parallel top through keyboard upper surface, but presents certain angle (angle is less) with keyboard upper surface, then arrives optical receiver 23.Like this, the distance of supposing light signal and keyboard upper surface is described predetermined value, in the time that the distance of input body and keyboard upper surface is less than described predetermined value, light signal will be transfused to body and block, when optical receiver 23 can not receive light signal, the distance that now can judge input body and keyboard upper surface is less than predetermined value; Otherwise if when optical receiver 23 can receive light signal, the distance of judgement input body and keyboard upper surface is greater than described predetermined value.
Wherein, in the camera detection mode shown in Fig. 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 keyboard upper surface from keyboard side.The principle that camera 24 is taken shutter 241 is also to receive the light signal that shutter 241 reflects, therefore, suppose that the light signal of certain reflection and the distance of keyboard upper surface are described predetermined values, in the time that the distance of input body and keyboard upper surface is 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 photographing by judgement (the initial background image during without input body and the background image while having input body), whether the distance of judging input body and keyboard upper surface is less than predetermined value; Otherwise during away from keyboard upper surface, this camera 24 can not photograph this input body, can only photograph again the background image that only includes shutter 241 at this input body.Therefore, can be by setting the height of shutter and camera, just can be according to the photographic images of this camera, judge whether the distance of input body and keyboard upper surface is less than described predetermined value.
(2) capacitance detecting mode: the electric quantity change that detects the conductive layer arranging on described keyboard; In the time detecting that described electric quantity change meets predetermined condition, judge that the distance of the upper surface of described input body and described keyboard is less than described predetermined value.Now, can adopt the capacitive transducer detection mode shown in Fig. 5: on keyboard 21, arrange one deck conductive layer 25, in the time that input body (as user's finger) comes in contact or approaches with keyboard upper surface, by the weak current transmission causing between human body and conductive layer 25, thereby cause the electric quantity change (as electric weight minimizing) of conductive layer 25; By the electric quantity change that detects that described input body causes, and then in the time that whether described electric quantity change meets predetermined condition, the distance of judgement input body and keyboard upper surface is less than described predetermined value.
Step 12, the distance between input body and the upper surface of described keyboard is less than described predetermined value, and while not producing described push button signalling, gathers the motion track of described input body at the upper surface of described keyboard.
Here, as shown in Figure 6, the present embodiment arranges a camera on computers, and (Fig. 6 is taking portable notebook as example, for the computing machine of other type, principle is identical), this camera (circle in Fig. 6 represents this camera) be placed in keyboard top (as directly over or 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 input body (as by finger) is in the time that keyboard upper surface moves, camera is identified the image collecting, obtain the position coordinates of input body, and then according to described position coordinates, calculate the motion track of described input body.
Step 13, according to described motion track, generates input command.
Input command described in the present embodiment can be specifically cursor control command, in order to control the movement of cursor on the displaying contents of computing machine.The input control of cursor control now and common notebook computer touchpad (touchpad) is similar: by will input body at the motion track of surface of keyboard, the movement locus of the cursor that is mapped to mouse on Computer display desktop.For example, moving direction, speed and distance according to input body at surface of keyboard, correspondingly control cursor in the moving direction, speed and the distance that show on desktop, and then realize and give directions operation by keyboard, to computer input cursor control command, in order to control the object of cursor movement.
Input command described in the present embodiment can also be gesture command, for example, when the motion track of described input body on keyboard is the circle of a sealing, generates a gesture command for lock-screen; When the motion track of described input body on keyboard is a "×" shape, generate one for closing the gesture command of current window.
The present embodiment is in above-mentioned flow process, terminal has keyboard input pattern simultaneously and keyboard is given directions input pattern, be less than described predetermined value in the distance meeting between input body and the upper surface of described keyboard, and while 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, input body is by any button on lower keyboard and produced corresponding push button signalling, and terminal will, according to normal keyboard input pattern work, receive and process above-mentioned push button signalling.
In the present embodiment, in the time that terminal is given directions input, just open image acquisition units (as camera); And in the time that computing machine carries out key-press 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 in the time not giving directions input.
The present embodiment can also pass through physical switch mode, carrys out control terminal and gives directions between input pattern and switch at keyboard input pattern and keyboard, makes terminal under synchronization is only operated in wherein a kind of pattern.Now, the present embodiment, before above-mentioned steps 11, also comprises:
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 inputted by physical switch.Physical switch can be manual extra toggle switch or keyswitch, and by stir or press/press out switch to different directions, control terminal enters different keyboard input patterns.Physical switch can also adopt to be similar in above-mentioned steps 11 and detect light detection mode or the capacitance detecting mode that the distance of input body and keyboard upper surface adopts and realize: please refer to shown in Figure 10 and Figure 11, two palmrest regions 31 that set in advance in terminal, 32 (these two palmrest region divisions keyboard below, be about to two palmrest region divisions on the main frame between keyboard and user), judge the distance in the first contact 33 and the first palmrest region 31, and whether the distance in second contact 34 and the second palmrest region 32 is all less than predetermined threshold value (two contacts can be two palm/wrists of user), when the distance that is less than predetermined threshold value and the second contact 34 and the second palmrest region 32 in the distance in the first contact 33 and the first palmrest region 31 is also less than predetermined threshold value, automatic switchover keyboard input pattern is keyboard input pattern, in the time only having a contact (contact 33 or contact 34) to be less than predetermined threshold value with the distance in a palmrest region, automatic switchover keyboard input pattern is that keyboard is given directions input pattern.Like this, in the time that user's two hands are placed on respectively two palmrest regions on keyboard, terminal will enter keyboard key-press input pattern; When user is when only a hand is placed on a palmrest region on keyboard, terminal will enter keyboard and give directions input pattern.The contact is here different with aforesaid input body, contact by with whether the contacting of palmrest region, supervisory keyboard key-press input pattern, in practical application, this contact can be user's wrist; Whether aforesaid input body contacts with keyboard upper surface, is the controlled condition that track gathers, and inputs body and be generally user's finger or input pen etc. in practical application.
In the present embodiment, enter keyboard at computing machine and give directions after input pattern, open image acquisition units (as camera); Exit keyboard at computing machine and give directions after input pattern, close the detection system (or 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 in the time not giving directions input.
By physical switch, control terminal enters keyboard and gives directions after input pattern, and the present embodiment can also receive the push button signalling producing after button on keyboard is pressed, and according to described push button signalling, carries out corresponding operation.
Concrete, as a kind of embodiment, in the present embodiment, can receive the push button signalling producing after any button on keyboard is pressed, and receive after described push button signalling, carry out left mouse button operation in cursor current position.Left mouse button operation comprises that left button clicks and left button double click operation, for example, receives only in the given time once described push button signalling, carries out left mouse button single-click operation; If push button signalling described in receiving twice in the given time, carries out left mouse button double click operation.Here, if continue to receive described push button signalling, can also carry out mouse drag operation according to described push button signalling, that is, when initially receiving described push button signalling described in the object at cursor position place pull.
As another kind of embodiment, the 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, receiving after the push button signalling of described one (or a class) button generation, carry out left mouse button operation in cursor current position; Receiving after the push button signalling of described another (or another kind of) button generation, carry out right mouse button operation in cursor current position.Same, left mouse button operation here also comprises that left button is clicked, double click operation, 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, the push button signalling that can also produce according to described one (or a class) button is carried out mouse drag operation.
Can find out from the above, the present embodiment has the following advantages:
1) owing to adopting keyboard upper surface to give directions the region of input as keyboard, with respect to the touch pad input of traditional portable notebook, the keyboard upper surface of the present embodiment can provide larger input area, therefore can be convenient for user input operations.
2) with respect to only adopting camera collection motion track, and then the mode of control cursor movement, the present embodiment can provide the accuracy of input, and can avoid inputting the problem of maloperation, its reason is: prior art is only inputted the motion track of body by camera collection, for example, in the time that user thinks that mouse beacon moves to right, input body can be moved right, to attempt to input a track moving right.Because user action has the feature of " back and forth " conventionally, after input body is moved right, conventionally can habitually input body be turned back to initial position again.In this case, camera cannot determine when and start gather and when stop gathering motion track, therefore camera collection to may be a reciprocal motion track, want the track moving right of input not conform to user.And in the present embodiment, user, in the time wanting that carrying out keyboard gives directions input, will input body near to or in contact with keyboard upper surface and not produce push button signalling, now the collection of motion track will be triggered; In the time that user wants to stop inputting, will input body away from keyboard upper surface, can trigger and stop motion track collection, thereby make the track collecting meet user's expection, reduce the problem of input maloperation.
Further, terminal can also comprise a display unit described in the present embodiment, and described input method can also, further by the mode of Overlapping display, be added the image of input body to show in image to.Fig. 7 shows a kind of application scenarios of above-mentioned Overlapping display processing, in the time that user operates on keyboard upper surface by hand, can see and comprise the directly image of the control to Action Target of user's hand on display unit.Now, input method described in the present embodiment, in the time gathering the motion track of described input body at the upper surface of keyboard, also comprises:
Step 21, gathers the first image that comprises described input body.
Here, can pass through image acquisition units 71, gather the image that comprises described input body (as the user's hand 72 in Fig. 7), locate the position of described input body, analyze the motion of described input body.Also can the distance between input body and the upper surface of keyboard be less than described predetermined value, and while not producing described push button signalling, just start to control image acquisition units 71 and go collection to comprise the first image of inputting body.
When image acquisition units 71 is carried out image acquisition to input body, in the image collecting, also comprise background image except described input is external, as keyboard image.The image that the present embodiment can directly collect image acquisition units 71, as described the first image; The image that also can collect image acquisition units 71 is further processed, and filtering background image wherein only retains the image of described input body, as described the first image.
Step 22, adds described the first image in the original displayed image of described display unit to.
Here, described original displayed image can be the true picture on desktop, as the shortcut icon on desktop or window, can also be the virtual content that terminal produces, and uses for user's operation and observes the picture that user operates as treated etc.
Here, when the image of described input body is added in 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, change the position of original displayed image by pulling mode, and the size of change original displayed image etc.Again for example, image acquisition units collects input body and has drawn a "×" at keyboard upper surface, now the image of this input body will synchronously be shown at display unit, and the action that this input body is drawn "×" on current window shows, and then generate corresponding current window shutdown command according to "×", current window is closed.Further, can also, by motion track Overlapping display own in original displayed image, show that "×" is in window, until user finishes input.
Finally, the input method of the terminal based on described in above embodiment, the present embodiment provides a kind of terminal, and as shown in Figure 8, this terminal comprises:
