Embodiment
Fig. 1 schematically shows a kind of communication terminal that is used for NFC, structure of mobile device of comprising, mobile device is communicated by letter with described communication terminal provides output with the orientation control output unit according to mobile device.Shown system has comprised three communication terminal CT1, CT2 and CT3.In the example shown, output unit comprises display device OD1, projector (not shown) and two loudspeaker OD2 and OD3, display device OD1 has display screen, shows display message DI1 on display screen, and projector is projected in display message DI2 on the wall in room.Replacedly, can form display by video wall that comprises several display screens or the projector that generates big image together.For example, display message may be merchandising, advertisement, music playlist, pollbook, recreation input and museum's information etc.Mobile device MD1, MD2, MD3 carry out NFC (near fieldcommunication, near-field communication) with communication terminal CT1, CT2, CT3 respectively.First system comprises communication terminal CT1, CT2 and output unit OD1, OD2, OD3.The second communication system comprises communication terminal CT3 and projector.In two systems, the relative position of the relative position of communication terminal CT1～CT3 and output unit OD1～OD4 all is known, thereby the information D I1 of demonstration, the position of DI2 are known.
In first system, first user who holds mobile device MD1 points on the screen of display device OD1 the position by mark 30 indications with mobile device.Because mobile device MD1, MD2 are respectively adjacent to communication terminal CT1, CT2, they are known with respect to the position of display message DI1.This is enough to the orientation of mobile device MD1, MD2 is sent to communication terminal CT1, CT2 respectively.According to orientation that transmits and the assumed position of mobile device MD1, MD2, communication terminal CT1, CT2 can determine the position that mobile device MD1, MD2 are pointed.Communication terminal CT1, CT2 insert mark 30,31 in display message DI (see figure 2), the mark among the display message DI1 30,31 is presented on mobile device MD1, the MD2 position separately pointed.
Mark 30,31 is used to the place that he points to user feedback.For example, point to the same area with the time longer and can take specific action than the schedule time.For example, if be marked in the button of demonstration, will carry out the defined action of this button.Replacedly, the user can press the button on the mobile device MD1, indicates the action relevant with the indication zone to be performed.
In an identical manner, the user can indicate sound should begin to play or stop broadcast one among mobile device MD1 directional loudspeaker OD2, the OD3.
It is unnecessary that two mobile device MD1, MD2 all communicate by letter with each autocorrelative communication terminal CT1, CT2 that is positioned at diverse location.Can have a plurality of NFC communication transceivers in same communication terminal CT1, perhaps, two or more mobile device MD1, MD2 can be near single NFC transceivers, thereby and carry out NFC with single communication terminal CT1 and communicate by letter.Single communication terminal CT1 can be mutual with a plurality of output units.
Though very directly perceived, the unnecessary position that should insert mark that mobile device MD1 is pointed to.For example, can suppose, not depend on the orientation of mobile device MD1, when setting up NFC, mark must be positioned at the precalculated position on the screen.Mobile device MD1 all can be on indicated direction when setting up NFC with respect to its all change in orientation of orientation movement indicia.
In second system, projector carries out projection to the display message DI2 that shows button B1～B4.Communication terminal CT3 determines the position that mobile device MD3 points to, and if the position pointed to of mobile device MD3 when being arranged in zone that button covered of button B1～B4, this button among highlight B1～B4.Equally, though very directly perceived, mobile device MD3 should point to described button should be optional by the position of highlight.For example, can suppose that do not depend in the orientation of mobile device MD3, when setting up NFC, button B1 is by highlight.All change in orientation of mobile device MD3 can be interpreted as from the center of button B1.
Fig. 2 shows the block diagram of mobile device and host computer system.Mobile device MD1 comprises near field communication unit 20, communication unit 21, orientation sensor 22 and personal identifier storage 23.Host computer system HS comprises near field communication unit 10, communication unit 12 and controller 11.Though near field communication unit 10 shown in Figure 2, communication unit 12 and controller 11 are arranged in communication terminal CT1 physically, other framework also is feasible, that is, controller 11 and/or communication unit 12 are not arranged in communication terminal CT1 physically.As shown in Figure 1, host computer system can be supported a plurality of near field communication unit 10, and these communication units are arranged in identical communication terminal CT1, perhaps is arranged in different communication terminal CT1, CT2, CT3.Suppose, but not necessarily, single communication unit 12 and single controller 11 be enough to make host computer system can with the different mobile phone communications that is recorded on the host computer system.
The near field communication path CP1 that the near field communication unit 20 of mobile device MD1 (for example being mobile phone or PDA) provides the near field communication unit 10 with communication terminal CT1 to communicate.Usually, so that these two parts are when being positioned at the other side's near-field communication scope each other, near field communication path CP1 is activated automatically when mobile device MD1 is moved to the close enough communication terminal.Usually, this short relatively near field range is a centimetre magnitude, for example 20cm.Alternatively, mobile device MD1 can comprise a wider communication unit 21.The optional communication unit 12 of this communication unit 21 in communication terminal CT1 provides to have than the bigger communication range communication path of communication path CP1 CP2.Increase wider communication path CP2 and have following advantage: the place of just mobile device MD1 being taken to close enough communication terminal CT1, in case by making mobile device MD1 fully come to begin communication simply via near field communication path CP1 near communication terminal CT1, even when mobile device MD1 has moved out the scope of near-field communication, also can keep communication so by communication path CP2.For example, can provide communication path CP2 according to bluetooth or WiFi standard.But, can realize any wireless communication protocol.
Optionally the unique identifier PI of mobile device MD1 is discerned in personal identifier storage 23 storages uniquely.By via near field communication path CP1 and/or communication path CP2 this unique identifier PI being sent to host computer system, host computer system just knows that it and which mobile device MD1 communicate.
Near field communication unit 10 provides the directed information that receives OI1 to controller 11.Wider communication unit 12 provides the directed information that receives OI2 to controller 11.Usually, the directed information OI1 that receives is identical with OI2 with directed information SD.But, directed information OI1 that receives and OI2 can be the version of codes of directed information SD, and this version of code needs controlled device 11 decodings.The coding that needs directed information via the optimal communication of communication path CP1 and CP2.According to the use pattern of mobile device MD1, any activates communication unit 10 or communication unit 12, and perhaps, communication unit 10 and communication unit 12 all activate.In start-up course, when mobile device MD1 entered near-field communication with communication terminal CT1, near field communication unit 10 should keep activating always and is activated up near field communication path CP1.Then, communication unit 12 and 21 becomes to activate to take over and communicates by letter.In the time of can also only the signal intensity in detecting near field communication path CP1 is less than predetermined value or when detecting mobile device MD1 and being positioned at outside the near-field communication scope, just activate communication unit 12 and 21 owing to communication path failures.Controller 11 is controlled the switching ON/OFF of communication unit 10 and 12 respectively with control signal CS1, CS2.NFC is used to mobile device is verified, or in fact mobile device users is verified that after this, set up unique preferable secure data and connect, for example, bluetooth connects.Replacedly, NFC unit 10 can be in state of activation so that can detect any approaching mobile device MD1 always.
Mobile device MD1 has the elongation form with axle intuitively among the embodiment at one, and this is defined as the pointing direction of mobile device MD1.The position of pointing in the information D I1 that shows is this and the intersection point of the information D I1 of demonstration.
In a kind of interchangeable structure, 11 of the controllers of host computer system provide the position that mobile device MD1 points among the information D I1 that shows.For example in output unit OD1, carry out the indication CS3 of this position among the information D I1 that shows.In this structure, controller 11 does not need to provide the information that will be shown.
Can operate this system according to three following step protocol.
The first step, the user mobile device MD1 is remained on communication terminal CT1 NFC unit 10 near, start login protocol.Host computer system is verified this user by mobile subscriber's mobile device MD1 (for example, mobile phone).At Qualify Phase, the safety between communication terminal startup communication terminal CT1 and the mobile device MD1 and unique communication path CP2.In proof procedure, user interactions may be needed, for example, password or personal code work may be needed to input.In case the user logins, communication terminal can be from mobile device MD1 gathered data or be stored in the data of communication terminal or (for example) necessary information of retrieval the data retrieved from the internet, the further option with the personalization of the information D I1 that allows bill under the items for merchandising situation or demonstration.
In optional second step, communication path fades to wider communication path CP2 from NFC CP1 path.The mode of user transparent is seamlessly carried out the conversion of NFC to (for example) Bluetooth communication.The user does not need to involve on one's own initiative in this transition of communications.
In the 3rd step, activate direction-pointing function.Electronic compass can comprise a 2D sensor, and must be held horizontally to obtain correct sensing or azimuth information, perhaps can comprise the 3D sensor of a slope compensation, and this sensor provides position angle and elevation information.Position according to the position of the known location of the communication terminal CT1 in system supposition mobile device MD1 and communication terminal CT1 is identical.Mobile device comprises that also the GPS receiver determines its position.For example, if the position of communication terminal CT1 is unknown in system, if perhaps mobile device MD1 to have been moved apart the high precision of actual position of communication terminal CT1 and mobile device MD1 suitable, then this is suitable especially.In order to improve the correct location of mobile device MD1, can give extra indication of user (for example, by the marked region on the floor) and understand fully where he may remain on mobile device MD1 (for example) close communication terminal CT1.Replacedly, point to basically in the process of same position, zone or output unit simultaneously at mobile this mobile device MD1, by monitoring average pointing direction, system can estimate the position of mobile device MD1.But, if the user wishes to change between output unit, for example, be transformed into second output unit from first output unit, system should detect this conversion, otherwise the variation on the orientation of mobile device MD1 still can be interpreted as the variation of directed position in first output unit.If the user sets up the NFC link near its mobile device MD1 is remained on communication terminal CT1, CT2, CT3, can obtain this automatic detection.Replacedly, by activating specific user's input (for example button), the user can indicate this incident.For all output units of no space connection on limited solid angle, monitor that (moving) average pointing direction is only effective to single output unit, perhaps effective under loose condition.In this case, host computer system provides deixis for a plurality of output units.An example is the combination of display on the wall, thereby the user can seamlessly roam on different displays when the mobile phone with him points to, comprises the notion that monitors average pointing direction.
The user carries out with it by the output unit OD1 in the pointing system alternately.Be shown information D I1 if this output unit provides, the position of sensing is visible.The button of mobile device MD1 can be used as click function.Replacedly, the sensing axle around mobile device MD1 tilts or rotates to be used as the analog or digital input.Direction-pointing function does not need to be restricted to single output unit OD1, covers but can have the space that comprises a plurality of output unit OD1, OD2, OD3.
The position component of system must be known.All positional informations can be predefined in the controller 11, perhaps are transfused in system calibration step in the controller 11.Preferably, positional information is stored in the controller 11 with database format.The combination of the orientation of the positional information of employing system element, the supposition of mobile device MD1 or actual position and mobile device MD1, the directed zone that can calculate directed output unit or output unit.
Replacedly, can adopt from the special-purpose indicator device of at least one reference position and carry out calibration process, to allow to fill or upgrade as initial point the database of the calibrated pointing direction of output unit OD1～OD3 with the position of indicator device.The combination of the pointing direction of the correspondence of at least two reference point and indicator device makes system calculate the 3D position of output unit OD1～OD3 with respect to indicator device by adopting triangulation principle or repeatedly triangulation principle.Owing to user's original position impliedly is provided by the position of NFC terminal CT1 when the user logins, therefore in login process, has not needed the user to carry out other calibration.
The mobile device MD1 that employing has direction-pointing function has the following advantages: single NFC terminal CT1 allows the user to select being shown between a plurality of projects of information D I1.This pointing method uses easily than the input of numbering.The input of numbering but, can for example be provided for the mobile device MD1 that does not have direction-pointing function simultaneously.Because mobile device MD1 does not need just can point to the regional close contact that the information OD1 that shows is shown the information OD1 of demonstration, so direction-pointing function allows more system design flexibility.In addition, owing to the distance between zone that the information OD1 that shows is shown and the user increases, therefore have only communication terminal CT1 need prevent intentional destruction.
