Below, information processing method according to a first embodiment of the present invention will be described in an instantiation of interactive system.

Fig. 4 A illustrates the side view of the interactive system according to embodiment of the present invention instantiation, and Fig. 4 B illustrates the front elevation of the interactive system according to embodiment of the present invention instantiation.

Illustrated in Fig. 4 A and 4B, in the instantiation of the embodiment of the present invention, this interactive system 300 comprises electronic equipment 200 and input equipment 100, and this electronic equipment 200 is notebooks, and this input equipment 100 is pointer.

Particularly, this electronic equipment 200 at least comprises display unit 10.This display unit 10 comprises display screen, for showing a graphic user interface to user.

Such as, this fluorescence excitation film 20 can adopt the mode of laser excitation.The laser excitation of fluorescent material is the one in various forms of optical excitation, and its utilization has the one or more laser beam being enough to make fluorescent material utilizing emitted light or luminescent energy.In other realizes, the optical excitation of this fluorescence excitation film 20 also can be produced by non-laser light source, and this non-laser light source has the energy being enough to excite the fluorescent material used in display unit 10.The embodiment of non-laser exciting light source comprises various light emitting diode (LED), light modulation and other such light source, that is, its wavelength sent or frequency spectrum can excite the fluorescent material that the light of higher-energy can be converted into more low-energy light.

Particularly, in exemplary configurations, following layer material can be comprised successively from outside to inside in display unit 10: cover glass, these fluorescence excitation film, color filter and display element etc.Like this, fluorescence excitation film 20 can be made can be subject to the protection of cover glass and to avoid wearing and tearing, and the light that the transparency of fluorescence excitation film 20 also can make display element send can not be stopped.

Pointer 100 at least comprises a body main body 40, image acquisition unit 50 and excitation source 60.

This body main body 40 is for playing support and fixation to other unit in pointer 100.

This image acquisition unit 50 can be such as camera or optical sensor etc., is embedded in one end or other positions of pointer 100, and for obtaining the response light that this fluorescence excitation film 20 is launched in response to the excitation of excitation source 60.

This excitation source 60 is for launching exciting light to fluorescence excitation film 20.It can be the single light source or the multiple light courcess that send a kind of wavelength light, or also can be send the single light source (that is, this single light source can launch the light had compared with wide spectral) of multiple different wavelengths of light or send the multiple light courcess (namely each light source launches a kind of light of wavelength respectively) of different wavelengths of light respectively.

In this instantiation, user can use and grip the display unit surface execution touch-control action of this pointer 100 at notebook 200, to form interaction gesture, makes this notebook carry out the first operation according to this interaction gesture.

It should be noted that, the present invention is not limited thereto.But, embodiments of the invention can also be applied to other one or more input equipments (such as, laser designator) with electronic equipment (such as, personal computer, panel computer, mobile phone, multimedia player, personal digital assistant, super, intelligent television etc.) between any reciprocal process.

As illustrated in fig. 3, described information processing method comprises:

In step S310, input equipment transmits the first optical signalling to electronic equipment.

When user wishes to use input equipment (in this instantiation, pointer) 100 to carry out operating electronic equipment (in this instantiation, notebook) 200, first this user is two device power-on.

After being powered up, this notebook 200 can by display unit 10 to user's display graphics user interface.Although be integrated with fluorescence excitation film 20, because this fluorescence excitation film 20 is transparent, so it can not block user normally watch this graphic user interface in the front end (that is, near the side of user) of display unit 10.

Next, user can carry out this computing machine of Operational Note 200 by this graphic user interface and completes operation needed for oneself.Particularly, this user can grip pointer 100 and carries out touch-control action, to form interaction gesture on the surface of the display unit 10 of notebook 200.Preferably, in an embodiment of the present invention, this touch-control action can without the need to touching the surface of display unit 10.Certainly, even if pointer 100 touches the surface of display unit 10 when user performs this touch-control action, this can not affect the normal running of this method too.

As mentioned above, the interaction gesture that user performs on the surface of display unit 10 can be a series of input trajectory, and it comprises one or more tracing point.Below, for convenience of description, being assumed to be by this interaction gesture is a single-click operation.

Such as, when user to wish in the display unit 10 at notebook 200 one of display can operand (such as, application icon) perform single-click operation, with choose or open this can operand time, this user can grip pointer 100, and makes the part being integrated with excitation source 60 in pointer 100 aim at this can operand surface towards display unit 10 to move.

In the process of pointer 100 towards the surface movement of display unit 10, this pointer 100 can pass through excitation source 60, the position of operand can transmit the first optical signalling to the display unit 10 of notebook 200 at this.This first optical signalling has first wave length and the first energy.

Illustrated in Fig. 4 A, in pointer 100, this excitation source 60 can be two paster type light emitting types (LED), is attached to the nib of pointer 100, can aim at easily to make user.The first optical signalling that this excitation source 60 is launched can be visible ray or invisible light.Such as, the wavelength coverage of this visible ray is 400-700 nanometer (nm), and this invisible light can be wavelength coverage be the ultraviolet light of 10-400nm or wavelength coverage is the infrared light of 770-2000nm.

But, the present invention is not limited thereto.As mentioned above, this excitation source 60 can be the single light source or the multiple light courcess that send a kind of wavelength light, or also can be send the single light source of multiple different wavelengths of light or send the multiple light courcess of different wavelengths of light respectively.

In step s 320, electronic equipment generates the second optical signalling according to the first optical signalling.

Correspondingly, in notebook 200, display unit 10 receives the first optical signalling launched by excitation source 60.Particularly, display unit 10 rear end is positioned at (that is, namely in the arrival of this first optical signalling, side away from user) display element before, first optical signalling absorbs as exciting light by this fluorescence excitation film 20, then launches the second optical signalling, responsively light.This second optical signalling has second wave length and the second energy.

In one example, the exciting light that this excitation source 60 is launched can be ultraviolet light.Preferably, the wavelength of this ultraviolet light is 365nm.In the case, down conversion physical phenomenon can be there is.Such as, fluorescence excitation film 20 launches visible ray in response to this ultraviolet light, responsively light.

Particularly, compared with visible ray, ultraviolet light has shorter wavelength and higher energy.Correspondingly, when luminescent substance (that is, fluorescence excitation film 20) absorbs ultraviolet light when launching low-energy visible ray, ultraviolet light is visible ray by down conversion, this is due to when ultraviolet light is converted into visible ray, the energy level reduction of ultraviolet light.

In another example, the exciting light that this excitation source 60 is launched also can be infrared light.Preferably, the wavelength of this infrared light is 880nm.In the case, up conversion physical phenomenon can be there is.Such as, fluorescence excitation film 20 launches visible ray in response to this infrared light, responsively light.

Particularly, compared with visible ray, infrared light has longer wavelength and lower energy.Correspondingly, when luminescent substance (that is, fluorescence excitation film 20) absorbs infrared light when launching high-octane visible ray, infrared light is visible ray by up conversion, this is due to when infrared light is converted into visible ray, the energy level rising of infrared light.Because energy level rises, so in the process of up conversion, need more than one infrared light photons could launch a light photon.

Although describe the conversion of exciting light to response light by two examples above, the present invention is not limited thereto.Such as, except invisible light, the exciting light that this excitation source 60 is launched also can be visible ray, such as, without the bluish violet band of light of obvious observability.Preferably, the wavelength of this royal purple light can be 405nm.In addition, in addition to visible light, this fluorescence excitation film 20 is encouraged launched response light also can be invisible light (such as, infrared light or ultraviolet light).

In fluorescence excitation film 20 transmitting response light (the second optical signalling) period, in order to pointer 100(can be obtained namely, excitation source 60) at display unit 10(namely, fluorescence excitation film 20) middle position coordinates of giving directions, in the response light that fluorescence excitation film 20 is launched in response to this exciting light, adding the positional information of corresponding tracing point, making the positional information of tracing point that pointer 100 can be determined from being formed on display unit 10.

For this reason, according to the precision of identification, fluorescence excitation material (that is, fluorescence excitation film 20) can be divided into multiple band of position, and make the band of position of wherein being triggered can transmit feedback information to pointer 100.Because fluorescence excitation film 20 at least covers the Zone Full of display unit 10, so obtain the positional information of pointer 100 in fluorescence excitation film 20, also just obtain the coordinate information of pointer 100 in display unit 10.

In a first example, fluorescence excitation film 20 can be designed to, comprising multiple bands of position can pointer 100 launch identical exciting light excitation under, launch the response light of different wave length (that is, color).

Particularly, the identification precision of whole display unit be 4(such as, simply display unit is divided into upper left, lower-left, upper right and four, bottom right part) when, launch red light under the excitation of the ultraviolet light that the upper left of fluorescence excitation film 20 can be made to launch at excitation source 60; Sodium yellow is launched under the excitation of the ultraviolet light that the upper right portion of fluorescence excitation film 20 can be made to launch at excitation source 60; Blue light is launched under the excitation of the ultraviolet light that the bottom left section of fluorescence excitation film 20 can be made to launch at excitation source 60; And launch green light under the excitation of the ultraviolet light that the lower right-most portion of fluorescence excitation film 20 can be made to launch at excitation source 60.

Like this, such as, when the image acquisition unit 50(installed in pointer 100 such as, optical sensor) when detecting that the response light that fluorescence excitation film 20 feeds back is blue light, this pointer 100 just can judge that position that active user gives directions is the bottom left section of display unit.

Above, be 4 to be illustrated for identification precision.Obviously, when identification precision higher (such as, being N), only need fluorescence excitation film 20 to be correspondingly divided into N number of part, make this N number of fractional transmission go out the light of N kind different wave length, and ensure that image acquisition unit 50 can identify this N kind light exactly.

In the second example, fluorescence excitation film 20 can be designed to, comprising the excitation of identical exciting light that can launch in pointer 100 of multiple bands of position under, launch the response light comprising the pattern distribution of different location.Such as, this location pattern can as shown in the figure above Fig. 4 B.

Such as, in the process forming fluorescence excitation film 20, patterning (pattern) PROCESS FOR TREATMENT can be carried out to it, make each band of position can under the excitation of exciting light, launch different coded data images (such as, one-dimensional bar code, two-dimensional bar etc.) or positioning image.

Below, still with the identification precision of whole display unit for 4(such as, simply display unit is divided into upper left, lower-left, upper right and four, bottom right part) situation be described.

Particularly, when using bar code, the coded data of two bits can be used simply to identify four of fluorescence excitation film 20 parts.Such as, coded data 00 can be utilized to identify the upper left of fluorescence excitation film 20; Coded data 01 can be utilized to identify the upper right portion of fluorescence excitation film 20; Coded data 10 can be utilized to identify the bottom left section of fluorescence excitation film 20; And coded data 11 can be utilized to identify the lower right-most portion of fluorescence excitation film 20.Further, formed fluorescence excitation film 20 time, make comprising four bands of position under the excitation of exciting light, the one dimension or two-dimensional bar that comprise above-mentioned four kinds of coded datas can be launched respectively.

Like this, such as, when in pointer 100 install image acquisition unit 50(such as, optical sensor) detect that response light that fluorescence excitation film 20 feeds back is formed when comprising the bar code image of coded data 10, this pointer 100 just can judge that position that active user gives directions is the bottom left section of display unit.

In addition, particularly, when using positioning image, four kinds of different positioning images can be used simply to identify four of fluorescence excitation film 20 parts.Such as, the first positioning image can be utilized to identify the upper left of fluorescence excitation film 20; The second positioning image can be utilized to identify the upper right portion of fluorescence excitation film 20; The 3rd positioning image can be utilized to identify the bottom left section of fluorescence excitation film 20; And the 4th positioning image can be utilized to identify the lower right-most portion of fluorescence excitation film 20.Further, formed fluorescence excitation film 20 time, make comprising four bands of position under the excitation of exciting light, above-mentioned four kinds of positioning images can be launched respectively.

Like this, such as, when in pointer 100 install image acquisition unit 50(such as, optical sensor) when detecting that the response light that fluorescence excitation film 20 feeds back forms the 3rd positioning image, this pointer 100 just can judge that position that active user gives directions is the bottom left section of display unit.

In like manner, above, be 4 to be illustrated for identification precision.Obviously, when identification precision higher (such as, being N), only need fluorescence excitation film 20 to be correspondingly divided into N number of part, make this N number of fractional transmission go out the different location pattern of N kind, and ensure that image acquisition unit 50 can identify this N kind location pattern exactly.

In addition, preferably, one's own fluorescence excitation film 20 can also be customized for each notebook 200, under the exciting of the exciting light making the fluorescence excitation film 20 of the first notebook 200 only can launch in the first pointer 100 being exclusively used in this first notebook 200, just to produce response light.Like this, fluorescence excitation film 20 can be avoided to be subject to surround lighting or to be exclusively used in the excitation source interference of other electronic equipments (such as, the second notebook 200), and making the operation confusion reigned of user in notebook 200.

In step S330, electronic equipment transmits the second optical signalling to input equipment.

After display unit 10 generates in response to the excitation of pointer 20 response light comprising tracing point positional information, this response light can be sent to pointer 20 along desired trajectory by this display unit 10.

Particularly, the transparent fluorescent posted in this display unit 10 front end excites after film 20 illuminated by the excitation source 60 of pointer 100, responsively light and inspire the specific wavelength designed in advance light or location pattern, as the positional information fed back to pointer 100.

Correspondingly, pointer 20 can receive this response light by image acquisition unit 50 from electronic equipment, to determine the positional information of the tracing point that pointer 20 is formed on display unit 10 according to this response light after a while.

Particularly, image acquisition unit 50 takes light or the location pattern of the specific wavelength be illuminated on the surface of display unit 10.

Such as, when this response light is visible ray, this image acquisition unit 50 can be visible image capturing head or visible light optical sensor.At this moment, graphic user interface normally cannot be watched in order to make user can not be subject to the interference of this response light in display unit 10, the region occupied by this response light can be made very little, like this, user is when using this pointer 100 to carry out touch-control, and the nib of this pointer 100 can block response light and incide in user's eye.In addition, in order to the response light avoiding small size causes follow-up identifying operation to occur error, preferably, high magnified glass can be added before this image acquisition unit 50.

When this response light is invisible light, this image acquisition unit 50 can be invisible light camera or invisible light optical sensor etc.

In step S340, input equipment obtains the positional information of the tracing point that input equipment is formed on the display unit according to the second optical signalling.

Response light wherein by launching different wave length is determined in the first example of positional information, and this image acquisition unit 50 can identify the wavelength of response light or color.After the wavelength identifying response light, the mapping table of wavelength and position coordinates can be obtained in the storer of pointer 100.Then, by carrying out inquiring about the position coordinates determined on the display unit 10 corresponding with this specific wavelength in this mapping table.

As mentioned above, when in pointer 100 install image acquisition unit 50(such as, optical sensor) when detecting that the response light that fluorescence excitation film 20 feeds back is red light, this pointer 100 just can judge that position that active user gives directions is the upper left of display unit 10.

Response light wherein by launching location pattern distribution is determined in the second example of positional information, and this image acquisition unit 50 can identify and extract, to obtain the positional information of tracing point location pattern distribution.

Such as, when this location pattern distribution is as coded data images (such as, bar code image) time, this image acquisition unit 50 can extract coded data from the second optical signalling of responsively light, obtain the coordinate information of described tracing point by decoding to described coded data, and described coordinate information is defined as described positional information.

Particularly, this image acquisition unit 50, after the picture photographing the bar code image formed by response light, extracts this bar code image from this picture.Then, this bar code is decoded the coded data determined indicated by it.Then, by determine the position coordinates on the display unit 10 corresponding with this coded data with the mapping table of position in inquiry coded data.
