Wearable display interface client

Summary of the invention

The present invention relates to a kind of during operation for short-range, carry out the display interface worn of wireless two-way communication, relevant method with server, and the system that comprises this interface and server.The embodiment that wears the basic series of interface according to the present invention comprises and drives processor (general or figure, have or do not have storer on the plate, have or do not have display and other one or more I/O drivers on the plate) power supply, this processor operationally is coupled to visual display unit and wave point, and wherein this interface further comprises and is used for thin client is connected to user's the health or the coupling arrangement of dress ornament.

In a series of embodiment, coupling arrangement is used for preferably can wearing the wrist that chain of interfaces is received the user by bangle, and in another serial embodiment, coupling arrangement is used for wearing the neck that chain of interfaces is received the user.In the first serial embodiment, the little bob of boxlike (locket) of wearing on the interface attempt imitation wrist-watch, and in second series embodiment, that interface attempt imitation is hung or neck.

The basic function that can wear interface is that (host server or master are called " server " hereinafter jointly, and arrange regardless of the communication protocol of preference " main frame " or " master " as the wireless display apparatus of host server or master; Can wear interface and be known as " client computer ", even term " appurtenant machine " may be more suitable in some cases).The video data that can wear interface can adopt following form: at least one visual image that is used for showing on visual display unit of being regulated by host server is carried out coded data, perhaps by the video data of the host server this locality that can wear the interface conversion.The benefit of last example is to have reduced the bandwidth demand that at least one visual image is carried out the wireless transmission of coded data, and under the situation of motion mimics image, because it is less to be launched or to be transformed into the visual image size of the image on the visual display unit, the refresh rate of visual display unit is increased.Yet the advantage of back one example is that host server does not need to revise its visual display unit output can be worn the local display buffer size of interface with coupling restriction; These operations are handled by this interface.

Preferably, can wear interface and be made up by the display of high pixel density (high resolving power or small pixel pitch), this display uses lcd technology or Organic Light Emitting Diode technology to make up.Alternative technology comprises screw image (gyricon) display (referring to http://www2.parc.com/hsl/projectors/gyricon/).The advantage related with merging such display is: when refresh display, just use power.Use the benefit of extremely lower powered display to be: under the prerequisite without any power requirement, image can be shown continuously.This technology makes the user of the embodiment of the invention can imitate wrist-watch, for example, when doing like this, is used for showing desired images being indifferent under the prerequisite of power utilization.The image that shows can comprise the image of table direct picture (watch face image) or any other user expectation.

Because technology or cost restriction, it may be unpractical obtaining general circular visual display.In this case, some embodiment of the present invention can further comprise the base (bezel) that square display is cut into the sub-circular display.The display geometry shape that reduces can be encoded into can be worn in the interface, makes when server emission during to the data of picture coding, considers the display sizes that reduces, and perhaps as mentioned above, the processing of the enclose pattern of wearable interface is transform data correspondingly.In addition, can expect and since non-technology or money, i.e. style reason, single visual display unit can be modified.Under situation about organizing certainly, the buckle-type base can be used to revise the aesthetic features that can wear interface.Be linked to the type of the base that can wear interface by sensing, the visual display data can suitably be regulated to be fit to be positioned at observable display.Thereby the type of each base can have the unique identifier such as contactor, the border in the observable visual field of its sign display, and allow to wear the characteristic of interface or the visual output of server modifications, to mate the observable visual field.

Feature of the present invention is at server and can wears the short relatively operating distance of the two-way communication between the interface.In history, wireless communication infrastructure has related to the scope that increases between the radio node, thereby reduces the necessary capital investment of infrastructure (for example, the LEO satellite communication is to cell tower) of setting up expectation.Alternately, can use a large amount of repeater node cheaply, but healthy and strong more signal tranmission techniques and the node link infrastructure of this solution requirement.On the contrary, the present invention attempts effective two-way communication range is reduced to short relatively distance, for example, and 10 meters or littler.Because can wear interface is individual for the user, and because it relies on the still local operation that distributes, so the server of expectation will be configured near the user necessarily and be generally permanent resource.As below describing in further detail, the present invention is optimized for local the use, and can rely on a large amount of servers, but as long as the conflict between them is minimized.

Thereby it is non-server-specific that another feature of the present invention can be worn interface.In an example, host server can comprise the Wireless Telecom Equipment such as honeycomb or pcs telephone.In this example, the user can have operationally and phone coupling () loudspeaker/microphone apparatus (" audio frequency apparatus ") preferably wirelessly, such as the headphone with Bluetooth function (headset), operate as just figure (static or moving image) display device and can wear interface.Yet, in such example, must manage and both communicate by letter as the phone of the host server of two equipment; If phone becomes and do not turn round, then visual services and audio service all are terminated.Yet, if can wear the main frame that interface also is used as audio frequency apparatus, in a single day then run into the suitable host server that another is used for wearing interface, just can recover whole Presentation Function (this is called the link transmission, wherein can wear interface and be passed to another server from a server).For example, if lose with wireless telephonic the connection, then can set up another with suitable wireless enabled personal computer is connected, therefore, (quilt that can wear in the interface is called out or received telephone number such as being stored in from the information of wireless telephone session, perhaps in addition stored I/O) can be passed to new host server, and can take suitable action (VoIP with calling party or take over party is connected such as foundation).Based on the agreement of being implemented, can carry out the translucent switching of user, make talk or exchange side between voice and/or data communication less interruption.If a plurality of feasible servers are positioned at the two-way communication range that can wear interface, then must use prioritisation scheme, it can be dynamic or static.Dynamic assignment will require user's input by the inquiry response session, and static assignment will provide priority value at a plurality of possible servers.Priorization can be considered the degree of approach, for example, user's the cell phone that enables has the priority that is higher than the farther physically call box that similarly enables, and the estimation of ID that perhaps can be by the uniqueness related with each potential server and descriptive character string is by autotelic driving.

Another feature of the present invention is to use host server to carry out healthy and strong computing function, such as speech recognition.Though what make that wearable device carries out speech recognition existingly makes great efforts to attempt to have single solution, embodiments of the invention distributed be used for intensive application (such as at host server and can wear speech recognition between the interface) computing cost.Though can wear interface need only minimize as " dumb terminal ", selected embodiment of the present invention provides and can wear interface and store specific data of user about user's acoustic pattern.When doing like this, host server only needs to have and operates general speech recognition software and use, CASSI speech recognition engine (session Computer Corp. such as Conversay, Lei Mengde, Washington, the U.S. (Conversational Computing Corporation, Redmond, WashingtonUSA)).In case suitable session begins, host server just at user's sense of hearing file of possible uniqueness to wearing the interface poll.In case accessed or preferably temporarily copied to server, the lard speech with literary allusions session of basis/action of voice will obtain especially high translation precision.In addition, comprising as safety equipment of user's sense of hearing file of the uniqueness of storage: only the sound of authorized users or characteristics of speech sounds will optimally drive the identification application.For this reason, user's sense of hearing file can be stored among the non-volatile EEPROM or can wear in the similar storer of interface, and can be by by sign indicating number (pass code) protection, to prevent the undelegated modification/remove/replace to the data file.

Another feature of the present invention relates to energy storage or generates the use of equipment, with and integrated in each embodiment of the present invention.Along with quick exploitation based on organic substitute of the energy storage equipment of metal to routine, can wear interface and can use energy storage equipment flexibly, be preferably rechargeable, such as lithium ion battery based on polymkeric substance.Alternately, can use the micro fuel cell technology, wherein the fuels sources that obtains easily such as alcohol (for example, vodka) can be used the electric current that is used for equipment with generation.Certainly, can use conventional power bunkerage such as dry cell (alkalescence or other).Described power supply can be provided with in the enclosure or in the outside of shell.

Yet, ideally, and in order to minimize the size of the shell that is used for display element and related circuit,, be considered to useful distributing power to store and management component by wearing on the zone that interface covers.Therein among the embodiment of display imitation table, power supply is preferably accommodated or is comprised and be used for wearing the coupling arrangement that chain of interfaces is received the user.In selected these embodiment, shell is for removing from coupling arrangement (such as wrist strap or bangle).By this way, the user can have two bangles, and one is used to wear, and one fixed recharge domination.When being dropped under the predetermined threshold by the available horsepower of the bangle worn, the user is notified, and this is true and can change bangle then; Backup battery or non-volatile storage parts change the maintenance interface preference and the function of manipulate at this.The advantage of these embodiment is to exist interface seldom to handle, and the operation of Switching power is very fast with simple.Yet, should provide suitable mode to prevent the accidental short circuit of power supply, such as using suitable sealing technique at (perhaps between power contact and environment) between shell and the bangle, perhaps use non-contacting power coupling scheme, such as inductive coupling and the alternate manner that will be recognized by those skilled in the art.

As to the substituting of the example of previous embodiment, other embodiment will comprise that the bangle of removable power supply and display casing are integrated.Because this is integrated, not that the power that certainly exists exposure transmits contactor between outer casing of power supply (for example, bangle) and display casing, this has just reduced accidental short risk.Yet, during replacing or recharging, requirement is replaced or recharged to removable power supply it is removed, this all is not real for all users.The example of embodiment is the same as described above, and the induction charging system can be used for keeping the suitable insulation of the relative environment of power supply, should use suitable obstacle in addition between one or more power supplys and environment.

In the shape factor (form factor) that hangs, can use similar methods, wherein a chain part is equal to the bangle part among the wrist embodiment on function.In addition, in the shape factor that hangs, other possibility is available: one or more battery can " attached " to being the item chain part of decorative pattern (consistent or with its quadrature) with the item chain part, and when the receiver that is used for one or more batteries is coupled to the shell that is used to show on electricity, in case exhaust, just can be exchanged.

Have embodiment immovable, rechargeable power supply and further require to comprise the charging source of charging inlet, it is preferably at the little shape factor of the outside of equipment to keep expecting.Charging inlet can adopt the form of the plug of docking station (docking station) or separation, and its selection is considered as design problem.Have movably, the embodiment of rechargeable power supply also requires to be used for device that power supply is recharged, device although it is so will imitate shell probably, during use, so one or more power supplys are housed in this shell.

In selected embodiment, can wear interface and further comprise the device that is used to provide and/or receive audio frequency, no matter be the device that provides and/or receive audio frequency via Radio Link, for example, wireless head-band earphone, or integrated morphology, for example loudspeaker and/or microphone, or the structure of link, for example telescopic wired loudspeaker and/or microphone.Following discussion will be imported embodiment at audio frequency then at first at audio frequency output embodiment, and last combination at I/O equipment.The intention of the disclosed embodiments is not an exclusiveness, but the combination of the disclosed technology of attempt explanation and the diversity of application.
