As discussing in more detail below, display key limits with the form of general picture, message (literal and/or figure), action can derive from the user through scripting language or form entry, perhaps through network from the webserver or from the computer of other relevant, such as the internet with one or more mechanisms.For example, this server or other computer can with e-commerce site, broker family, other the user or one independently keyboard business operation person is relevant.This general picture comprises series of displays device key and content corresponding or message identifier.Action comprises one or more orders, and such as utility command, its response key activates and/or responds certain machinery or customer status is performed.

This key display message is formatted and be sent to the Keyboard Control software that is used to show this key, and this key function suitably changes.In addition, respond the current application program that is activated, this general picture, message and action can be upgraded at least in part.This client's current active application program is automatically differentiated, and suitably redefines function and the literal or the image of this display key, and corresponding active application program is performed.Record or history file are produced with upgrading and are write down the behavior relevant with the display key, comprise that the user utilizes the mode of this display key.

This client comprises some software modules that are stored in the customer memory, and such as hard disk drive, and this module is carried out by client computer.The client of this demonstration comprises a server interface manager, a client manager module, a customer status detector controller, a cache database/agency, and action API (application programming interfaces), client's side event recorder, a browser, and keyboard USB interface.Relevant with this client browser is selectable cookies (cookie) modules, and it stores a user designation code.This identification code is discerned each client and/or each user uniquely.One " cookies " are files, and its storage is by the message of the relevant client computer of remote server use.In one embodiment, these cookies are automatically by server access, and when making this server of visit, this user does not need to import user's identification code at every turn again.Can certainly use other User Recognition scheme, such as password or the like.

Usually, this client software management and keyboard and remote server communicates by letter.This client software sends suitable message according to this customer status and is used for showing on the display key of selecting.Customer status as use herein can be the date of being represented by client's calendar/clock circuit, this client browser at present the URL IP address, and/or other based on other the software that is activated such as general picture Microsoft's word and that be attached to this state.Especially, this client's pattern is converted into a customer status.That is, a state is set according to the active application program, and this pattern (for example, Word SaveFileMenu or ExplorerWWW.yahoo.com/spons/indx.html) in application program

In the embodiment that gives an example, the state of each definition has the general picture of a qualification, and the general picture of each qualification has a unique ID.For undefined state, enclose the general picture of an acquiescence.This acquiescence general picture can specify 12 display keys correspondingly to show F1-F12 or can be so that display key goes to show that the title of popular website or paying make its title be presented at advertiser specific on this display key.Each general picture comprises for the definition of one or more display keys, to the definition of each display key with a unique identifier (ID).Client software detects display key and is activated, and at least in part based on the key that is pressed or key and/or customer status, carries out or activate appropriate command or action group.An action is the collection of operation keys definition (0-N key) and/or carries out a group system order.Word language is used in the collection of this definition and/or the order of definition.This literal language is used for supervisory keyboard, client operating system and/or client applications.Therefore, this action is synthetic with the definition of illustrating to literal from a series of internal command.These orders comprise the Windows shortcut, such as URL, Word file, program and SDK order.With regard to its function, script file (script file) is similar to a html file, comprising the order that will carry out and definition/field value.

For instance, this action can send order to browser or to the office of Microsoft application program.This order can be corresponding to the developer's of standard Microsoft network software development person's Kit (SDK) function or control, such as transmitting or return the surveyor of Microsoft function.Other action comprises and sends keyboard commands, action of request or information updating, shortcut instruction, such as an executable file that will move or the URL that will visit.In one embodiment, use the suitable developer's of Microsoft network software development person's Kit request to go to send direct instruction to application program execution SDK control.In another embodiment, can use the simulation of macro-instruction or key, though these technology are than using SDK control still less to stablize.

One of display key definition function has following three fields for example:

Key (key ID, message id or text, action/general picture ID or invalid), here

Key ID is the identifier that is used for the key that will define;

Message id is the identifier that is used to comprise the Message Record of displaying contents on the key that will be presented at definition;

Text is a text string that will be presented on the key that will define;

Action/general picture ID is the identifier that is used for the action/general picture relevant with the key that will define.If import one 0, not having action so is with the key that will define annexation to be arranged.

Because in this embodiment, this message comprises an action/general picture ID, and existing does not often need to specify individually an action/general picture ID in this key definition.

The example of action general picture will be described now.

Be first example of an action/general picture script file below:

Key (1, fg6576dfg55gd8s, 0);

Key (2, Kjgh5ghf5fghf876,0);

Key (3, " karismatech ", rte434jfghdfhed);

Key (12, jkhk54646hjghjg, 0);

Background sound (thesong.mid);

This example literal updating key push action table is used for display key 1-12, and plays a MIDI file " thesong.mid " in background information.As will be described in more detail below, key push action table is hinted obliquely at state, message and is moved corresponding key.

First key definition is for key 1, it be be stored in the have message id message of " fg6576dfg55gd8s " in content relevant, do not have clear and definite required movement.Second key definition is for key 2, it be be stored in the have message id message of " kjgh5ghf5fghf876 " in content relevant, do not have clear and definite required movement.The 3rd key definition is for key 3, and it is with text " KARISMATECH " and to have the action/general picture of identifier " rte434jfghdfhjed " relevant.The background sound order is used to call MIDI file " thesong.mid ".

For instance, when detecting certain and comprise domain name URL, such as when detecting the domain name that Explorer_www.[selects] the .com/index.html state time, above-mentioned literal may be performed.Be second example that comprises the individual command script file below:

SetURL (the www.buy.com/ product/index.html);

This above-mentioned exemplary language changes URL in the browser of an activation, carry out on client.In this was given an example, this script file was called as " rte434jfghdfhjed ", and it is action/general picture target of distributing to display key 3 in first example.The action that this action/general picture ID may respond previous execution is provided with in key push action table, for instance, and when a relevant state, such as the Explorer_www.shop.com/index.html state detected the time.When key 3 was pressed, this script file was performed, the website www.buy.com/ product/index.html that makes this browser go to visit to be positioned at this URL.

Now this client software module will be described in more detail.Cache database/proxy module is managed some high-speed caches or database, comprise a general picture high-speed cache, a message cache and an action high-speed cache, therefrom correspondingly fetch and store the general picture message that is used to be presented on the display key, and response key low pressure and/or customer status execution action.If the client needs a general picture or corresponding message and/or action, not current not being stored in the high-speed cache, this SIM (server interface module) module is connected in server, if it is online, and fetch necessary general picture message and/or action data, it then is to be stored in suitable client's high-speed cache.If this server is an off line, this request is to be stored in " request case " database (not shown), and when this server enters online the time, it is activated.When as an agency time, this cache database/proxy module provides the native client data, empties earlier to send inquiry to server.

In one embodiment, this cache database/agency receives request from customer management module, finds correct target, and target can be general picture, message or action here, and sends them to customer management module.This cache database/proxy cache is filled by SIM, it through the internet from the server retrieves target.If do not find this target in this cache database high-speed cache, an error code is returned to customer management module.This customer management module request SIM goes to download target from server then.

This general picture high-speed cache comprises a profile database that comprises the general picture record.A general picture record example comprises a general picture id field that is used to store an identifier relevant with this general picture, wherein uses this general picture ID can fetch this general picture.In addition, this general picture record comprises one or more message ids or pointer field, here each message id field be used to store accordingly, uniquely with one of display key relevant identifier.Therefore, if for example this keyboard comprises 12 display keys, 12 message identifier will be arranged corresponding to these 12 display keys.This general picture record comprises that one stops field, is used to store the termination time and/or the date that are used for this general picture.This termination time and/or date can be imported programmable timer.In detecting by programmable timer, date of expiry and/or time that response reaches, in order to guarantee to use up-to-date general picture, by this customer management module from new general picture of server retrieves.In another embodiment, in case fetch the general picture record, this termination field is examined.If these termination data and/or time reach or exceeds, fetch a new general picture record so.In one embodiment, this general picture id field is 16 bytes, and each message id field is 16 bytes, and this termination field is 6 bytes.Certainly, also can use other field and field length.

This message cache comprises Message Record or target.The example of a Message Record comprise comprise appropriate display on corresponding display key literal or the content of graphic image, at display text and image (for example glimmer, roll, reverse and show or the like .) execution result, and an action identifier is used to fetch corresponding action.In addition, this Message Record comprises a date of expiry and a termination action.This termination field is used to store a termination time and/or a date that is used for this general picture.This termination action field is used to store the pointer to an action, reaches in case it detects this termination time, just carries out this action.For example, this termination action can replace existing message with the message of new information or acquiescence.Even this assurance is in the time of an end-of-message, display key can not stay blank.This message is fetched from cache database according to its ID.Therefore, for example, this Message Record can comprise a message id field, a content field, a result field, an action id field, a date of expiry and a termination action, as following:

Message id: 16 bytes

Content: 132 * 32 pixel images (4.125k bit map)

Result: 2 bytes

Action ID:16 byte

Date of expiry: 6 bytes

Stop action: 1 byte

If this keyboard key has color monitor, an additional byte can be used for specifying the color content that will show.If the display color to each pixel can independently be specified, nibble or one or more byte can be used to specify the colour of this given pixel so.

Action record comprises this action script file and action ID or pointer.In one embodiment, except having independent general picture record and action record, two function combinations are called action/general picture record or target in a record or target type.This action/general picture target provides unique title, is called action ID, can reappear by it.This action/general picture target is used as and comprises one or more orders and message pointer or the script file record of message id and date of expiry and/or time.This action/general picture order can respond the key activation and/or respond certain customer status and apply the order that is performed.One or more orders can be irrelevant with keypad function.For example, this action/general picture target can be used for calling an audio file, goes to play in background information such as a mpeg file.Therefore, action/general picture target is for many key definitions of one or more keys and/or a group system or applies the order that will carry out.

This customer status detector controller detects client's state.For example, under the situation of explorer, this state can be the URL that activates at present.If this client uses at the Office of Microsoft, this state representation menu be activate at present application program.For example, under the situation of the Word of Microsoft, the menu of activation can be format form dialog box or other dialog box.This state also can comprise current date and time.As previously discussed, this state can be used to select general picture or the action/general picture that will use, and what will be presented on the display key thus.

When display key is activated or presses, the order that this client's side logout module identification is carried out, and the details that storage is correlated with in record or history file.For example, the date and time display key is activated, and is registered to the user's of client software user ID, machinery or customer status, display key with or the non-display key pushed, and if user-defined action/general picture be used for this display key, this action of execution also is recorded.Subsequently, on this server side, this log file is analyzed, and upgrades the user's request fileinfo in view of the above.This log file is periodically sent to this server and is used for analyzing.Time and frequency can optionally be limited by user and/or server software, are sent to server with this time and frequency record file.For example, when this user did not use client usually, this user can select once.

Except above-described process, customer management module is used for allowing different users to go to sign in to client software, makes different general pictures can be used for different users.In order to login this system into or as different user's logins, this user pushes the key of an appointment, such as Home key.In replying, this customer management module is removed to be presented on client's monitor screen or is listed on user's the display key having related account.The user can select a user who lists then, this user of highlight, and push a suitable mouse or keyboard key.

This client software comprises some layouts or connection table, comprise and hint obliquely at the user list of user to corresponding user ID, hint obliquely at the state layout of state to corresponding general picture ID, and when activating an appropriate display key, hint obliquely at state and message key push action table to the action that will carry out accordingly.

This user list be included in the client work of going up or with the user's of client software registration title or user identifier.During user's enrollment process, this user list is filled.This user list hints obliquely at user name or identifier arrives and that subscriber-related acquiescence general picture or action/general picture.When detecting a nondeterministic statement, perhaps detect a state, do not have clear and definite definition general picture or the action/general picture relevant with it, this acquiescence general picture or action/general picture work.This tabulation is optionally disposed by this user.Therefore, each user has his or herself acquiescence general picture or action/general picture, and it is carried in the login automatically.This mapping function is as follows:

User → general picture ID (that user's acquiescence general picture)

If use this action/general picture target type, so:

User → action/general picture ID (that user's default-action general picture)

State table is hinted obliquely at or is linked general picture ID or ID to specific state of action/general picture, and designated user optionally.For example,

User=John

State=Explorer www.yahoo.com/ motion/indx.html

Action/general picture ID=TgHfgFGgf453tfHY

Stop=11/11/00

Therefore, when this user is John, and (in the time of Explorer www.yahoo.com/ motion/indx.html), this general picture relevant with action/general picture ID:TgHfgFGgf453tfHY is used, and needs only date of expiry of 11/11/00 not reach to detect state.This state table is optionally to be disposed or filled by user and/or remote server.State and perspective view are to select, and make suitable display and action be activated for given state and user.For instance, if the state of the expression Word of Microsoft application program is activated, the general picture of this link is relevant with the literal that is presented on the display key with suitable being used to.For example, the text relevant with this general picture can be so that this article word " preservation " on first display key, occurring, " printing " is to being presented on second display key, and " spelling Chk " is to being presented on the 3rd display key.

Because this state table mapping also is based on the user optionally,, depend on that the user has different mappings for a given state.If use this general picture target type, this mapping function is:

If state+user → general picture ID uses this action/general picture target, this mapping function is so:

State+user → action/general picture ID

In one embodiment, this state table has two added values for the state of a regulation, an empty state and a free state.If, be appointed as free state not from such state of server requests general picture or action/general picture.This gives tacit consent in the middle of all states, carries out above-mentioned request up to.If from action/general picture of server requests or operate condition, be appointed as empty state; But this server does not have an action/general picture for that state to be limited.Optionally, if there is a relevant action/general picture, but this action/general picture stops, and can be appointed as empty state.

Because sky or free state also are not attached on an action or message, this user can set up his action and message, and add they to a sky or free state.In addition, this user can receive the control of some display key, allows him dynamically to be defined for the action of these keys.In preset time, for example after two months, this user definition can optionally be set to automatically stop.Optionally, this server can be by the control of winning user-defined key again for user-defined key given content and action.

When a display key was pressed or activates, this key push action watch chain connect this state and message (image and result) and gives action with " RUN ".When a display key is pressed, a form takes place consult.This key push action table is dynamically updated, and as the result of previous action, it is stored in this record.This mapping function is:

If the key that general picture ID+ pushes → action ID uses this action/general picture target, this mapping function is so:

Key → action/general picture the ID that pushes

This client moves API and sends and solicited message from this server, given server IP address and from this server restoration result.

In addition, this client software comprises a message editor procedure, and corresponding to the demonstration with the display key, the literal that its conversion is write is a graphical format.For example, this pixel display has the 132x32 bit map here, and this message editor procedure converting text message is to be applicable to 132 * 32 pixel formats that are presented on the display key.This allows the user to go to limit themselves key and corresponding message.

Referring now to Figure 1B this keyboard hardware structure is discussed.As illustrational, keypad function is handled by CPU (CPU) 132, it can be one and derive from the fixedly EZ-USB AN2131Q CPU of chip, the microcontroller of integrated Intel 8051 compatibilities, and comprise that hardware supports and support USB for low level USB signaling calculate.In another embodiment, this CPU132 can be a general microprocessor, microcontroller or the like.This CPU132 is connected to the keyboard keypad 126 that comprises display key through a multiplexer 128.This multiplexer 128 is used to scan this keyboard matrix, makes CFU to send to client computer by CPU132 through USB jack 142 then in case this key bounces and produces a scan code.As the home computer of routine, this client computer comprises a keyboard controller, and such as one of Simulation with I ntel 8042, its reception scan code and use are exclusively used in the hardware interrupts of keyboard (IRQ1) and signal the client computer processor.This client computer processor is deciphered this key of pushing then, and takes suitable action.In addition, which key is this client's manipulation module monitor is pressed, and makes it can carry out previously described operation.

This CPU132 also is connected to display key backlight 130.Wherein this CPU132 can connect or close display key backlight 130.For instance, this backlight can use the Densitron backlight to realize, part number SY-BLA6006.In one embodiment, each display key has one and separates controllable backlight.This allows backlight 132 just during use or consider special effects, is switched on when by spells the display key of selecting being flashed this backlight with the frequency of a selection.

The working storage that is reserved as CPU132 with the volatile memory 138 of the form of static RAM (SRAM) provides.In one embodiment, connect in case finish USB with client computer, the program package code that comprises acquiescence USB descriptor is by automatically from client computer is downloaded into this SRAM138.In addition, as the part of initialization procedure, CPU registration LCD register, and variable is initialised.These address decoder 136 decoding CPU132 addresses, and remove suitably to start this SRAM138.Nonvolatile memory 140 with the form of flash memory 140 or the like is used to store this CPU program code and acquiescence general picture, message and/or action.

In addition, this flash memory 140 can be used for storing unique keyboard ID, thinks that this keyboard 10 also can be by hard wire on the keyboard pcb or in a chip.Optionally, when for the first time the user operates his keyboard, this user designated one unique will with the related user ID of the ID of this keyboard.For example, this user ID can be to use keyboard ID as referring to the output of randomizer.This prevents that the people from measuring user's true identity from keyboard ID, so protects user's privacy.But keyboard ID can be as the part of swindle safeguard measure, with measure this keyboard whether be a forgery or a uncommitted keyboard.This enrollment process will begin the client, but at server record.

This flash memory 140 can optionally comprise a series read-out/write inbound port.In another embodiment, this keyboard ID can hard wire on the keyboard pcb or in a semiconductor circuit.

Fig. 1 C illustrates a software configuration that is used for keyboard.This module is carried out by keyboard CPU132.Major loop module 150 operation backstage keyboard tasks.Foreground task is carried out by the module that another one is operated on the drives interrupts basis.Therefore, this module is event driven, and is by external interrupt, outside input of CPU or timer interrupt enable.Middle task communication is carried out through one or more state machines.

Counting and configuration module 154 are carried out counting and configuration feature according to USB standard v1.1, and are used to set up the usb communication process.This counting and configuration module 154 send and receive the control transaction to USB module 152.As previously discussed, connect in case set up USB, program package is downloaded from client computer.This bag that downloads is supported this counting and configuration mode.Counting and configuration module 154 responses are from the standard USB request of client computer, and the standard of transmission USB device descriptor is to client computer.In addition, module 154 is set up packet type and is limited, and handles the usb signal exchange, comprises affirmation, non-affirmation and halted state, and sends the USB situation.

Module 156 is used for sending the keyboard scan code to USB module 152 from CPU132, is used to be transferred to client computer.When existing scan code to transmit, module 156 produces an interruption and gives the USB module.Module 158 operative norm keyboard scans and anti-jump function.Module 158 is periodically checked keypad, is used to change and the reading to eliminate wrong reading of this keypad of debounce.Module 160 is used for using whole outwards transaction to obtain the keyboard display position through USB module 152 from client computer hinting obliquely at.This position is hinted obliquely at and is temporarily stored among the FIFO, and in the buffer that is copied after a while into.

Module 162 fill order mode capabilities.In this embodiment, module 162 is application level protocols that an enforcement is used for the command mode operation of LCD control.This order is implemented by control output transaction.For example, module 162 customer in response computer instructions can be carried out following function:

Current LCD is set

The LCD address ram is set

The LCD rolling mode is set

Obtain the LCD show state

Preset module 166 is carried out aforesaid function of initializing, comprises register and initialization of variable.LCD writes/and 168 pairs of LCD display of read module write and read.In this embodiment, this LCD display is the equipment of memory map formula, and thereby by LCD write/read module 168 writes and therefrom reads.Bit map rolling module 170 is carried out the LCD display rolling function.Flashing of serial write/and read module 172 carries out writing and reading from the serial of the non-volatile flash memory of keyboard.

One of backlight driver module 174 control or be used to have keyboard display backlight illumination in limit perhaps has the cycle signal with the backlight of given repetition rate flicker.In one embodiment, in order constantly to have the backlight illumination, this backlight driver module 174 produces one and is used for the 50 Hz signals that backlight drives.Clock interrupt handler module 164 is handled the interruption that is used for LCD backlight and keypad scanning.

To be described in the server system of Fig. 3 illustrated now.The server system of this demonstration comprises the multiple software module that is stored in the server memory and is carried out by this server.This server uses the communication protocol that is discussed below to receive client requests or customer information by TCP in the port of a regulation via the internet usually, such as the user logging file.When receiving a client requests, for example general picture, message, action and/or other target, this server is analyzed this request, and responds with a suitable answer.If this server receives a user logging file, analyze this record by outcome record device and analyzer module.This server uses and is stored in configurable correlation table association requests and target in the independent SQL/Oracle server.This server also can be removed the computer received content that links from the mechanism with other by networking.In addition, this server tracks user account produces and stores general picture, action and the message that comprises advertisement.Be used to store this SQL database this sql server can or home server, perhaps can be for by one or more Local Area Network or the addressable server of wide area network (WAN).

The server of this demonstration comprises a customer interface administration module, server management module, SQL client manager, event recorder and analyzer module, a server action API module, a configuration manager, and this sql server comprises one or more SQL database.In addition, this server can comprise the IIS software of Microsoft.This database is used for memory address and other media contents and user account information.This database also can be stored the account balance relevant with the address, during the address that is shown lasting, and the information relevant with the audience of wanting.In addition, also store the information that the user relates to, comprise user identifier, user's income, user's interest, user's buying habit and the ad identifier that is used for the address on the current user's of being presented at keyboard.Use SQL (SQL) code can realize this database, be used to limit, upgrade and inquire about relevant database.For example, this database can be realized with many business data libraries, comprise relational database product of Microsoft's sql server, Oracle or the like.

In one embodiment, the request of customer in response, this address or other content are provided by server.This " according to needing " system that is known as.The server interface administration module that is arranged in client is connected to server by network, and produce a request, such as an advertisement or message request, a general picture request, and/or an action request, it is received by the customer interface administration module on server side.The request that server response provides by information requested is such as the displayable medium on suitable client's keyboard display key of being presented at of one or more addresses or other.Use ASCII, HTML, other scripting language, bit map data and/or use other data formatting technology that this message or advertisement can be provided.Each message can optionally have a specific contiguous identifier relevant with it, makes that the address that exists can be by server tracks.

Especially, in one embodiment, by inquiring about this sql server, this server response that is positioned at the target of request receives the target request from the client.This request comprises the type and the Target id of user identifier and target request, and more details ground is described below.Set up this SQL query from user identifier or group identifier and target request type (general picture, message or action) and Target id.This group identifier is used to assemble one group of user and links them with the characteristic action of sharing.For example, this action/general picture and/or message that allows to share goes to distribute to all users in a group.For example, this group can limit from geography, such as the user all in the Manhattan.When there is sale in the Manhattan storage, can automatically be sent for the message that this sale is identical, be used to be presented at all group members' display key.

A target can be a fixed object that does not rely on user identifier, perhaps can be the variation targets of considering user identifier, perhaps other a randomization structure.Response is used for the request of a variation targets, and server finds a group identifier relevant with user identifier, makes a target randomization in this group then.For example, for identical state, will provide the different version of an advertisement based on user or group ID.This feature based on the SQL query language provides big flexibility ratio in the self-defined action that is used for single user and/or customer group.Based on the action of previous execution, can dispose this action such as being recorded in the record those.

This server is analyzed client requests, and redirects the SQL query that suitable this type request of processing is given in this request.In one embodiment, a suitable SQL query tabulation is limited in the sql server, and its translation-protocol content is a SQL query.

One that is the SQL query tabulation below example is described.This SQL query tabulation has following field:

Target type, from ID to ID, the SQL literal

When sending a request that is used for target, will provide following parameter:

Target type and Target id.These parameters will be to be used for the input that form is consulted.

The result begins to take shape a target and SQL literal.

For example:

Type	From ID	Deliver to ID	The SQL literal
				Action	????0	????L	From ... the middle selection
Message	????0	????M	From ... the middle selection
				Message	????aaaaaaaaaaa	????zzzzzzzzzzzz	From ... the middle selection

Therefore, having action or the message of ID in a specific ID scope can be relevant with single SQL literal.

For instance, if initial request is: target type=" state ", and Target id is state ID, and this initial SQL request will be user+state → action ID.And then from sql server request action ID, at this time: action ID → action 1/ action 2/ action 3 (if this initial request is: this inquiry may directly receive, target type=action, Target id=action ID).Nearest general picture is the action of action more than ID.In this inquiry, will select at random for one of return action, and send back to the client as initial request response to him.

Be configured administration module and can dispose and fill this tabulation, it can optionally be carried out on an independent server.This Configuration Manager updates stored in this tabulation on the sql server through SQL query.In addition, use sql command can manually upgrade this tabulation.

This client's medium request can comprise multiple information.If there is one, this request can comprise a user identifier.In addition, can comprise subscriber-related data, such as URL by the current website of user capture, and/or the URL of the website of visit recently.Client's module data comprises working method or state, the identifier relevant or other the current content displayed and the position of those addresses with the address, and perhaps the content part that also can be used as log file provides.Other relevant data such as computer hardware and/or software configuration information, also optionally provides about application messages of opening in client's side or the like.

In case the server interface administration module is carried out the received content data in this client, such as an advertisement or other video data, these data are analyzed and give suitable position through one or more keyboard device driver layer route, such as a key display.Because this content is downloaded to client, even when this user does not visit this network, advertisement or other content can optionally show.Keyboard device driver allows client operating system to remove the access key display, and notifies this operating system when with which key to press.In addition, in one embodiment, this server can provide order which make and to be stored on client's side the address or other content goes to be presented on suitable client's keyboard key.Use aforesaid editing machine, the address or other the content that are stored on client's side can be optionally by user's modification, according to font type, font size, color (supporting colour if this key shows) or the like.In addition, this server can comprise a message transformer module, it from a kind of format conversion content to another kind of form.For example, if this content is at the BMP form, this conversion module changes into a kind of form that is applicable to that this key shows.For example, if this key display is 132 * 32 pel arrays, each pixel only has one and closes and on-state here, and this BMP file is converted into 132 * 32 monochrome pixels forms.Similarly, if this key display can display color, this content will suitably be converted for being presented at can the display of display color on.

This server response comprises a client requests that comprises the header and the afterbody of data.This header comprises the information relevant with additional data.This information comprises the information about data type, and these data are shown if any here, how long these data will be shown, the blink speed of these data or the like.This server response can comprise one or more orders or action.In case can comprising corresponding key, these orders activate accessed one or more URL.This order or action also can be so that one or more application program be activated such as browser.Also can comprise the information that is provided with for server.This response data can comprise media content, such as one or more advertisements that are displayed on the corresponding keyboard key.These medium can comprise text and/or graphic symbol.

Referring now to Fig. 4 A-D, 5A-D and 7 example of the communication protocol between client-server is described, though also can use other agreement.Fig. 7 illustrates a sampling communication process 700.From state 702, this cache manger receives a request that is used for target from customer management module, such as general picture, message or an action.At state 704, the target that determines whether this request is in corresponding high-speed cache.If this target is in this high-speed cache, this target is retrieved at state 706 so, and is suitably used at state 710.Otherwise if the target of this request is lost (perhaps stopping) from cache database, at state 708, this customer management module uses this agreement to send a request that is used for this target to server.This request expression this lose objects type (general picture, state, action) and unique ID.Receive this target by this client from server at state 712, and use this target at state 710.As described below, this agreement also is used for transmitting file from client to the server, such as log file.

In this embodiment, there is 4 types communication, as follows:

1. ask-from client to the server, be used for the request of a target

2. response-, send to target of client from this server according to client requests

3. send-one file, send to server from the client such as a log file

4. confirm-confirm to be received by the file that this client sends by server

Server side action API provides response and confirms the preparatory function of a function and a given server IP address, and a selectable callback feature from client's restoration result.

As illustrational at Fig. 4 A, each communication comprises that one comprises and is used to comprise version number and communicates by letter or be used for the protocol massages head of the command field version field of memory command type (request=1, response=2 send=3, confirm=4).This version field is to be used for and version back compatible in the future.The structure of remaining field is determined in this order that enters command field.

For example, Fig. 4 B illustrates the afterbody of a request, comprises a user identifier field, a target type field and an object identifier field.The user identifier field is used to comprise the current user identifier that signs in to this system user.This target type field is used to specify the target type of being asked by client's use or American Standard Code for Information Interchange or other code (general picture=1, message=2, action=3).The distinctive identifier of target that this object identifier field is used to specify request.

Fig. 4 C illustrates the afterbody of a response.This target type field is used to specify the target type that is being sent to client's (general picture=1, message=2, action=3) by server.The distinctive identifier of target that this object identifier field is used to specify transmission.This aiming field comprises the target of transmission.

Fig. 4 D illustrates the afterbody of a transmission.This user identifier field is used to specify the user's relevant with the file that is sent to server by the client user identifier.This document type field is used to specify the file type that is sent by client (log file=1, cookies file=2 or the like).Size field is used to specify the file byte-sized, and this document field comprises the file of the reality of transmission.

In this example, do not confirm the afterbody that order is relevant with this.

In one embodiment, one or more above-mentioned protocol formats that discuss comprise an error detection and proofread and correct field that it allows to detect the transmission error and is proofreaied and correct by receiver.

A file and an example of confirming communication that Fig. 5 A-5D correspondingly illustrates the response of client requests, server, sent by the client.Particularly, Fig. 5 A illustrates one by 1.0 version client requests with user identifier 1fd5422 user, is used for a target type " message " with an object identifier Hgf32FdF.Send communication at Fig. 5 B illustrated server, in response, comprise the 1.0 version servers response of target type " message " with an object identifier Hgf32FdF, and this message.

Fig. 5 C illustrates and sends a file, in this example, send to log file of server, comprise that 1.0 version clients send order by the client, be used for a file type 1fd5422 user record, 20 K byte-sized and this log file with user identifier 1fd5422.Fig. 5 D illustrates one and confirms communication.

This agreement is used for connecting exchange message by TCP/IP.In the time of target of needs, this client is established to the connection of server (IP of server predesignates).This client sends a request or sends notice through connection, and wait-for-response or affirmation notice.At the appointed time, if having no to receive, this client will repeatedly try again for predetermined number of times.If does not also receive a response or confirm that this client disconnects, and this client manager returns an error code to this client API.

During single the connection, be possible more than a request.For example, if this request is to be used for a general picture, this customer management module will automatically be asked this message in its general picture.

As previously discussed, respond one or more incidents or machinery or customer status, can produce this client requests, comprise client's date and/or time.For example, this customer management module comprises a submodule, and calendar and clock that it periodically reads computer remove to determine date and time.This customer management module may or begin request in predetermined date and/or time then in date or time range.When of these times had existed, if this server is not in operation, when this server when being operational, this customer management module may begin content requests.Therefore, for example, this customer management module can from server per hour, every day, weekly and/or every month basis begin to ask adding advertisements or other content.This time can be by client-side software supplier, keyboard supplier, server and/or user program setting.In addition, this request can directly and/or manually be begun by the user.In one embodiment, these times can dynamically be changed by server.

In addition, in the special shopping time, during Thanksgiving Day on Christmas Day, this customer management module can be programmed and be begun request.This allows to provide effectively the advertisement time of sensitivity.For example, this customer management module can start the request to the advertisement server in the last week in Thanksgiving Day.In response, this server provides the address, comprises being used for the relevant macro-instruction of grain or the like.Therefore, for example, an advertisement that is used for " put in a suitable place to breed district turkey " can send the client to from server and be used to be presented at keyboard key.When this user pushes when showing the phrase key of " putting the district turkey in a suitable place to breed ", this user will automatically present a webpage that is used to sell the retailer who puts the district turkey in a suitable place to breed.This user can order this turkey from this website then.

In addition, the response user application program of on client computer, packing into, this client can start a request.For example, customer in response pack into a Web browser or an e-mail program can start a request that is used for the address.In addition, with the application program gang of packing into,, can start this request in case the scope of distinctive time or time occurs.

In another embodiment, also can use a content by pressing system, this startup of server content of being used on keyboard, transmitting here, for example, the address.Therefore, optionally need not clear and definite client requests data and can be pressed into client's keyboard display.This client can be notified online remote server client's existence, has or do not have distinctive registration process, and perhaps this remote server can detect the online existence of client through inquiry.In the embodiment of a demonstration, this client access internet and open a connection to server.This client " keeps tuning " up to separating from the internet.When this connection was unlocked, this server sent message to the client.In one embodiment, as previously described, this message comprises the header and the afterbody that comprise data.In addition, this technology provides the real-time messages of data from the server to client keyboard, and these data can derive from the third party here.For example, when certain stock price reached certain price, this user can inquire that his or his brokerage house goes to provide notice.When above-mentioned a kind of appearance, this investment broker can transmit a corresponding message and give server, and it was being pushed in 5 second time on the display key of appointment or flowing out data and result successively, and such as a flashing light, these data are provided by the investment broker.

Respond one or more conditions, this server is pushed content such as address and is used to be presented at keyboard key to the client.For example, this server can be monitored the website by client access, and based on this monitoring, selects which address to go to send to the client.Use is stored in the advertiser of the information response standard or the request of database wherein, and this server also can be pushed the address on distinctive client or customer type.This standard can comprise geographical position, user's sex, age marital status, education, income level or the like.For example, this server can be pushed an advertisement that is used for the Hollywood bowl and be had income Da Yu $40 in Los Angeles area, 000 all client.By another example, this server can be pushed an advertisement that is used for clothes and give and stay in all women within 3 miles of the retail shops relevant with this advertiser.In another example, an advertisement that is used for the date business can be pressed into user's keyboard, and this user is unmarried and on 30 years old.

Therefore, above-mentioned system can be used for renting or hire out the key display space at the basis that the time limit is arranged.Advertiser or other content provider can rely on advertiser's needs and budget to have long-term " renting ", perhaps short-term lease on this key display.This advertiser can utilize the server operator to set up an account, and has suitable amount deducted from this account.Therefore, be used to change the time during quantity when this keyboard is powered, this advertisement can show such as second, minute, hour, date, week, month or time, perhaps for good and all.In addition, this advertiser also can be at every turn to activating user's charge of the keyboard key display media relevant with this advertiser.In addition, this advertiser can collect the expense of different ratios for different users.For example, between 18 and 35, can collect the expense of higher rate to the male sex, secondly for the male sex between 40 and 60.

This advertiser can set up an account with the server operator, and has suitable amount deducted posted at different user's keyboards from this account as the address.The quantity that counts the account can be based on user's number, at the keyboard of the advertisement that shows, and the quantity of the time spot of demonstration, and/or insert display, the number of times of this advertiser's of user capture website by activating corresponding keyboard key.

The promoter that advertiser's company or name of product can be used as permanent or semi-permanent user's keyboard occurs.The said firm can provide or make this keyboard to go freely to provide or reduction or subsidized price replace the media content with the said firm and be presented on one or more key displays.

In one embodiment, this address or other media content can glimmer on one or more directions, flash, roll or the like, feasible attentiveness of catching the user better.Under the situation that the backlight type key shows, open and close and to carry out this and flash by changing backlight apace.For LED or FED based on display, pixel itself can be switched on and close.

Contest, complimentary ticket, perhaps given leaving can show on one or more key displays and optionally flash or glimmer, and help to keep the user to watch this key display and relevant advertisement attentively.For example, when this user activated the key of a demonstration contest, this user can automatically enter this contest.Similarly, if show a complimentary ticket advertisement, this user can obtain this complimentary ticket by hitting this key.This complimentary ticket can be an electronic coupons, a kind of Downloadable complimentary ticket, perhaps a kind of complimentary ticket of mailing the user to.Except that advertisement, this key can show URL, link, inlet, startup ecommerce behavior or the like.

Therefore, as mentioned above, the invention provides and promote function and use easily.All or some keyboard key with display can be devoted to advertise.The key that is not exclusively used in advertisement can use this user's or other programmable macro-instruction of deactivation to go the function of implementing to want by the user.Therefore, except quilt be can be used for the display ads, this keyboard also can be used as conventional equipment.

In addition, in one embodiment, this client's side form piece can automatically be discerned those and be arranged on application program on the user's computer and the corresponding Presentation Function of application program and the order that mutual key are adapted to and use.Similarly, this keyboard key can imitate this interface of internet site, such as menu.Therefore greatly by showing different menu functions and the easily addressable and outstanding mutual button of order within it, the performance of surfing program and task is simplified widely such as online shopping, enhancement operating efficiency and rise in value for this user.
