Embodiment
Below will explain portable electric device provided by the present invention and method of operating thereof by embodiment.But embodiments of the invention not must can be implemented in any environment, application or mode as described embodiments in order to limit the present invention.Therefore, be only explaination object of the present invention about the explanation of embodiment, but not in order to direct restriction the present invention.Palpus expositor, in following examples and diagram, has omitted and has not illustrated with the non-directly related element of the present invention.
The first embodiment of the present invention is handheld electronic device 1, and its schematic diagram is depicted in Fig. 1.Portable electric device 1 comprises a sensing element 11, a processing unit 13 and an interface 15, and processing unit 13 is electrically connected to sensing element 11 and interface 15.In addition, portable electric device 1 is connected to a computer 17 by interface 15.
Sensing element 11 can be the sensing element that an optical lens, a gravity sensor or other surrounding enviroment that can detect portable electric device 1 change.Processing unit 13 can be any in various processor well-known to those skilled in the art, central processing unit (central processing unit), microprocessor or other calculation elements.Interface 15 can be Bluetooth transmission interface, infrared transmission interface, universal serial bus (Universal Serial Bus; USB) interface, Wireless Fidelity (Wireless Fidelity; Wi-Fi) transmission interface or other can make portable electric device 1 and computer 17 carry out wireline interface or the wave point of line.
For example, when portable electric device 1 is moved to a second place (: a user moves to the second place by portable electric device 1 by primary importance) by a primary importance, its sensing element 11 can produce multiple sensitive informations 106.Processing unit 13, first according to these sensitive informations 106, calculates a moving direction and a displacement.Then, processing unit 13 produces a control signal 102 that is loaded with this moving direction and this displacement, and interface 15 transmits this control signal 102 again to computer 17.
After computer 17 reception control signals 102, just according to the contained moving direction of control signal 102 and displacement, the cursor on the screen of control computer 17, makes cursor move to the second coordinate of 1 on screen by the first coordinate of 1 on screen.Must expositor, the corresponding relation between the contained displacement of the distance between the first coordinate and the second coordinate and control signal 102, can look its needs by user, is set by computer 17.
As shown in the above description, by the configuration of the first embodiment, user can control the cursor on the screen of computer 17 easily by ambulatory handheld formula electronic installation 1.
The second embodiment of the present invention is that sensing element 11 is defined as to an optical lens, and therefore the second embodiment is only the running relevant with sensing element 11 and how to process/use sense measurement information 106 with the difference of the first embodiment.Below the difference place for two embodiment is only elaborated, remaining running is identical with the first embodiment, therefore superfluous words not.
Because sensing element 11 is optical lens, therefore, user is in this portable electric device 1 of the upper operation of a working surface (not illustrating).For example, this working surface can be a finger surface or the textured surface of other tools.For example, in the time of the control device (: mouse) of user using portable electric device 1 as computer 17, user moves to the second place on working surface by portable electric device 1 by the primary importance on working surface.Palpus expositor, user also can change mobile working surface (for example: moveable finger before optical lens) into, and this kind of operator scheme also can be regarded as portable electric device 1 and moves to the second place on working surface by the primary importance on working surface.
In moving process, sensing element 11 carries out image capture to obtain multiple sensitive informations 106 to working surface; In other words, each sensitive information 106 is a pick-up image.Then, processing unit 13, just by these pick-up images of comparison, calculates moving direction and the displacement of portable electric device 1.Must expositor, how processing unit 13 judges that by multiple pick-up images moving direction and displacement are well known to those skilled in the art, therefore superfluous words not.
Implement in aspect in other, portable electric device 1 can more comprise a light source component (not illustrating).In the time that sensing element 11 carries out image capture to working surface, light source component can produce light source, to obtain comparatively bright pick-up image as sensitive information 106.Moreover, to implement in aspect in other, portable electric device 1 can more comprise an amasthenic lens (not illustrating).This amasthenic lens can be arranged at optical lens front, so that the imaging of optical lens falls within the better field depth of optical lens.Thus, the obtained pick-up image of sensing element 11 just can be comparatively clear, and processing unit 13 calculates moving direction and the displacement of gained also can be more accurate.
The third embodiment of the present invention is that sensing element 11 is defined as to a gravity sensor (G-sensor), and therefore the 3rd embodiment is only the running relevant with sensing element 11 and how to process/use sense measurement information 106 with the difference of the first embodiment.Below the difference place for two embodiment is only elaborated, remaining running is identical with the first embodiment, therefore superfluous words not.
Because sensing element 11 is gravity sensor, therefore, in the time that portable electric device 1 is moved to the second place by primary importance, sensing element 11 can be exported multiple output signals according to its return rate (report rate), and respectively this output signal is loaded with at least one acceleration information (for example: X-direction acceleration information, Y direction acceleration information and/or Z-direction acceleration information).
Further, if user is with larger strength ambulatory handheld formula electronic installation 1, because its translational speed is very fast, therefore the output signal of gravity sensor is loaded with larger acceleration information.Otherwise, if user is with less strength ambulatory handheld formula electronic installation 1, because its translational speed is relatively slow, therefore the output signal of gravity sensor is loaded with less acceleration information.
Then, processing unit 13, just by these output signals of comparison gravity sensor, calculates moving direction and the displacement of portable electric device 1.For example, the contained acceleration information of the visual output signal of processing unit 13 is directly proportional to displacement, and therefore, in the time that acceleration information is larger, the displacement that processing unit 13 calculates is just larger.
Follow-up, after computer 17 reception control signals 102, can, according to the contained moving direction of control signal 102 and displacement, control the cursor on its screen, make cursor move to the second coordinate by the first coordinate.
Fourth embodiment of the present invention please refer to the drawing 1.The Main Differences of the 4th embodiment and the first embodiment is that processing unit 13 more provides portable electric device 1 to stop at the treatment measures after the second place.Below the difference place for two embodiment is only elaborated, remaining running is identical with the first embodiment, therefore superfluous words not.
Particularly, the sensitive information 106 that processing unit 13 can produce according to sensing element 11, judges that portable electric device 1 stops at the second place.Afterwards, interface 15, according to the judged result of processing unit 13, transmits another control signal 104 to computer 17, makes computer 17 control cursor according to control signal 104 and moves to the three-dimensional on screen by the second coordinate on screen.
For example, portable electric device 1 can be according to the content of the custom setup control signal 104 of user's operating mouse.According to the custom of user's operating mouse, in the time that the retarded velocity of mouse becomes large, represent that user very likely carries out the movement of next round again, to make the cursor on screen approach rapidly the target that institute's wish is pointed to/controlled.Contrary, in the time that the retarded velocity of mouse diminishes, represent that the cursor on screen has approached the target that institute's wish is pointed to/controlled.
Consider the custom of aforementioned user's operating mouse, processing unit 13 can calculate the retarded velocity of portable electric device 1 according to these sensitive informations 106, then judges the size of the retarded velocity of portable electric device 1.For example, when the retarded velocity of portable electric device 1 is when large (: be greater than one first threshold value), the control signal 104 that interface 15 transmits can be loaded with a larger displacement, make computer 17 control cursor according to control signal 104 and move to distance the second coordinate three-dimensional (in other words, the distance between the second coordinate and three-dimensional is greater than one second threshold value) far away by the second coordinate on screen.
Contrary, for example, in the time of the retarded velocity less (: be less than the first threshold value) of portable electric device 1, the control signal 104 that interface 15 transmits can be loaded with a less displacement, make computer 17 control cursor according to control signal 104 and move to the nearer three-dimensional (in other words, the distance between the second coordinate and three-dimensional is less than the second threshold value) of distance the second coordinate by the second coordinate on screen.
As shown in the above description, custom when user's operating mouse has been considered in the configuration of the 4th embodiment, therefore, when user controls the cursor on the screen of computer 17 by ambulatory handheld formula electronic installation 1, can have and control more accurately effect.
The fifth embodiment of the present invention is a kind of portable electric device 2, and its schematic diagram is depicted in Fig. 2.Portable electric device 2 comprises sensing element 11,21, processing unit 13 and interface 15, and processing unit 13 is electrically connected to sensing element 11,21 and interface 15.In addition, portable electric device 1 is connected to computer 17 by interface 15.Because the portable electric device 2 of the 5th embodiment and the portable electric device of the first embodiment 1 is approximate, therefore will only describe the difference of the two below.
In the 5th embodiment, portable electric device 2 is provided with sensing element 21 compared with portable electric device more than 1.Therefore, in the time that portable electric device 2 is moved to the second place by primary importance, sensing element 11,21 all can operate, and processing unit 13 can carry out follow-up processing according to the running of sensing element 11,21.
Particularly, in the time that portable electric device 2 is moved to the second place by primary importance, sensing element 11 can produce sensitive information 106, and processing unit 13 can calculate a first direction and one first distance according to sensitive information 106, and its account form is identical with the mode described in the aforementioned first to the 3rd embodiment.Similarly, sensing element 21 also can produce multiple sensitive informations 108, and processing unit 13 also can calculate a second direction and a second distance according to sensitive information 108, and its account form is identical with the mode described in the aforementioned first to the 3rd embodiment.
Then, processing unit 13 determines moving direction according to first direction and second direction, and determines displacement according to the first distance and second distance.For example, the sensing element 11,21 that user can set portable electric device 2 is respectively as main and auxiliary sensing element.Now, if sensing element 11 produces sensitive information 106, but sensing element 21 does not produce sensitive information 108, and due to main sensing element normal operation, therefore processing unit 13 carries out follow-up processing with sensitive information 106.In other words, the moving direction that processing unit 13 determines is first direction, and the displacement determining is the first distance.If sensing element 11 does not produce sensitive information 106, but sensing element 21 produces sensitive information 108, due to sensing element 21 non-staple sensing element, the moving direction that processing unit 13 determines and displacement be all 0(that is, the cursor on the screen of computer 17 will can not move).
Again for example, user can not divide into main and auxiliary sensing element by sensing element 11,21.Now, can cause the result (for example: aforementioned first direction and second direction are contrary) of contradiction if processing unit 13 judges sensitive information 106,108, moving direction and displacement that processing unit 13 determines are also all 0.If processing unit 13 judges sensitive information 106,108 and can not cause the result of contradiction, the moving direction that processing unit 13 determines can be the mean value of first direction and second direction, and displacement can be the mean value of the first distance and second distance.
As shown in the above description, the configuration using of the 5th embodiment the various sensing element in portable electric device 2, therefore,, when user controls the cursor on the screen of computer 17 by ambulatory handheld formula electronic installation 1, can have and control more accurately effect.In addition, user also can select how to utilize these sensing elements (for example: only use one of them sensing element, or a sensing element is that main all the other sensing elements are auxiliary), increases the convenience on using.
Portable electric device 1,2 described in the aforementioned first to the 5th embodiment more comprises an input element (not illustrating), and this input element can be touch control screen, button and/or other and have the element of input function.In the time that input element is triggered, can produce an input signal (not illustrating), interface 15 can transmit this input signal to computer 17, makes computer 17 choose the corresponding content of cursor on screen according to input signal.By configuration input element, portable electric device 1,2 just can provide more complete function to give user.
The sixth embodiment of the present invention is a kind of method of operating of portable electric device, and its process flow diagram is depicted in Fig. 3.This method of operating is applicable to handheld electronic device (please refer to aforesaid portable electric device 1 and portable electric device 2), and in order to control the cursor on the screen of computer.

Then,, in step S303, the sensitive information being produced according to step S301 by portable electric device, calculates a moving direction and a displacement.Afterwards, execution step S305, transmits one by portable electric device and controls signal to computer, and this control signal is loaded with moving direction and displacement, make computer according to moving direction and displacement, a cursor of controlling on screen moves to one second coordinate by one first coordinate.
Implement in aspect in other, this method of operating can, with reference to the custom of user's operating mouse, provide other steps, to control more accurately the cursor on screen.Particularly, this method of operating can be carried out a step again, to judge that according to these sensitive informations portable electric device stops at the second place.Then, this method of operating is carried out another step again, controls signal to computer to transmit another, makes computer according to this cursor be moved to a three-dimensional by the second coordinate on screen.
Implement in aspect in other, in the time that an input element of portable electric device is triggered, this method of operating can be carried out a step again, to produce an input signal.Afterwards, this method of operating is carried out another step again, to transmit this input signal to computer, makes computer choose the corresponding content of this cursor on this screen according to this input signal.
Implement in aspect in other, in the time that portable electric device comprises multiple sensing element, this method of operating can repeatedly perform step S301 and S303, the multiple moving directions that obtain according to step S303 more afterwards and multiple displacement, decision finally will be sent to moving direction and the displacement of computer 17.
