II. Exemplary record unit controls and data recording process

As mentioned above, the present invention can implement in the record cell that comprises digitizing tablet, coordinate pen and relevant microcontroller and memory storage.Control and data recording process that the present invention also can be included on the record cell to be realized.Control and data recording process can be realized under appropriate software control by microcontroller.Attainable concrete control reaches in the relevant explanation at Fig. 8-12 with data recording process and reveals according to the present invention.

Data recording is that the detection by stroke and " incident " realizes.For the present invention's purpose, " incident " is a kind of situation of giving prospective significance, can define the variety of event of being convenient to write down or represent data stream.

Incident generally can or as automatically taking place by record cell or causing and be classified as the user.Automatically event is not from the incident that takes place and detect and be recorded under the situation of the special input of user.For example, can define the pen-up event that pen down event that the denotation coordination pen contacted with writing surface and denotation coordination pen have been mentioned from writing surface.Like this stroke can be defined as one start to write and one lift a series of coordinates that write down between the incident.Also can so that definition " press close to lift pen " incident, but this representations of events is mentioned near the zone that remains on the digitizing tablet from writing surface.This incident can arrive by monitoring a coordinate radio transmission and the input of starting to write, and can be recorded automatically.Similarly, can define " do not press close to lift pen " incident, this representations of events coordinate pen moves away to the position that suitable distance is arranged with digitizing tablet from writing surface.In addition, can also define such as " soft key " or switch and additional events such as lift, make to have specific meaning discussed in more detail below.

Fig. 8 provides an example of the process that is used for taking place automatically incident.As shown in Figure 8, at the duration of work of this device, the input of system can be monitored (800).When detecting foregone conclusion spare, for example press close to lift incident time (810), then the unique data string (820) of this incident of record identification.The time and date mark (830) of the time and date that takes place of system log (SYSLOG) presentation of events then.As described below, the time and date mark that record is associated with each incident is for the ease of the processing of stroke and event data afterwards.

Fig. 8 a represents the automatic detection of " soft key " incident.As the illustrated mistake of reference Fig. 1, soft key is a predetermined zone in the effective coverage of digitizing tablet.When having stroke data to take place in the presumptive area that detects at soft key, the soft key incident is taken place automatically by system.More particularly, as shown in Figure 8, monitor that in input system may detect the stroke data (812) that occurs in the soft key appointed area during (800).As response, call and the relevant program (822) of soft key startup this.

As mentioned above, some incident may be that the user causes.Fig. 9 shows the generation and the record of " new page " incident that the user causes.The new page incident is used for identifying the specific webpage of writing medium that will form follow-up stroke on it.Be associated with the identifier of specific webpage by the stroke data that makes record, make the user change the page by purpose.For example, the user can return the page and the new text of typing of before having write text on it.By the new page incident took place before writing once more on this page, the text of follow-up typing will be associated with suitable page identifier.This to write down stroke data after read to handle and can comprise that the various stroke datas that are used in different time record during the handwritten form text entry reconfigure full page.

Specifically, during surveillance input (900), may detect new page incident 910 referring to Fig. 9.The new page incident may be caused by operating switch or soft key or some other device by the user.When detecting the new page incident, from the further input of digitizing tablet be under an embargo (920).Then, the prompting user imports new page identifier (such as new page number) (930).Then, the identifier data of system log (SYSLOG) new page (940).At this moment, can make from the input of digitizing tablet effective 950.In addition, system also can further point out the user to import new page type (960).For example, the user may wish to point out that new page specifically is the address book page.When the input (970) of receiving from the user, system will determine to import and whether indicate specific page type or do not had page type (980).The data of sign specific webpage type will be recorded in (990) in the storer.Then, make input effective (950) and system return supervision input and record stroke data mode from digitizing tablet.

Second type of the incident that the user causes can be called " stroke sign " incident.Stroke sign incident is used to refer to the total common sign of certain stroke.For example, the user may wish that the concrete stroke group of indication should occur with certain font such as underscore, heavy body, highlight or italic in the digitized record of its handwritten form text.In addition, the user also may wish to specify the expression data of one group of stroke as special predefined type.The example of predetermined data types comprises address book entry, list items, calendar item, notebook item, check, expenditure account item, database items, reaches secret word.In addition, the user also may wish to indicate the stroke group for example to be input to specific application program, fax or Email handling with ad hoc fashion after a while.

Above-mentioned stroke characterizes incident and can take place by several means.The first kind of mode that relates to " linear model " of stroke sign is shown among Figure 10.As shown in Figure 10, during surveillance input (1000), microcontroller may detect the input (1010) that the indication stroke characterizes incident.This incident may comprise that the user that (for example) indication text should underlined soft key starts.Index line sexual norm data type is stipulated the data recording (1020) in data stream of incident then.The use that the linear model stroke characterizes will require the user all will excite the sign incident before writing the text of sign with after the text of writing sign.So the stroke data between two identical sign incidents will be handled by the stroke that system carries out being characterized by the sign incident.During this sign, LCD display can be used to provide linear model to characterize the prompting that incident has been excited to the user.

Other pattern also can provide stroke to characterize.The data of record should be labeled as specific type before in some cases, the user can determine.For example, the user may determine the notes of being done in the past should be input in the tabulation of " waiting to finish the work " project.In order only to finish this point with existing linearity specifications pattern, the user will be required or when it is write at first the specified data type, perhaps write this again, and will remember at this moment by linear model designation data type.Therefore, there is also a desire for other patterns of type standard.

An example of " circle-back " pattern of stroke sign has been shown among Figure 11.In general, the circle that stroke characterizes-back pattern allows the user for example by lifting soft key indication stroke type, and then by forming " the border stroke " of edges of regions that one or more indications surround the stroke of sign in it, indication is as the stroke that is pre-existing in of the type.Other shape at the edge in the form of the desirable circle of border stroke, " x " or any zone that can be used to draw.Like this, as pressing the border stroke that circle-back pattern forms, system can determine the stroke that has been carried out sign by the user as predefined type that those are pre-existing in by reference example.

More particularly, as shown in figure 11, when surveillance with circle-after pattern when input (1100), system may detect the user and cause stroke and characterize incident (1110).Then, system can write down circle-back pattern stroke and characterize incident (1120), and the prompting user provides the border stroke (1130) of the stroke of indication sign.Then, system is removing the stroke (1140) that prompting (1150) before can recording scheduled number.So, will comprise circle-back pattern stroke by system's recorded data stream and characterize incident, the border stroke that indication limits the predetermined number in the stroke zone that characterizes is followed in this incident back.

In addition, can also provide similar " circle-elder generation " stroke of one to characterize pattern.Circle-first pattern and circle-back mode class is that like part the stroke of sign is by the border stroke representation of predetermined number.Yet in circle-first pattern, the border stroke is led over circle-first pattern stroke and is characterized exciting of incident.Like this, in circle-first pattern, the data stream of record will comprise the border stroke of predetermined number, and the circle that heel one user is taken place-first stroke characterizes incident.

This system and then the delete function that can also provide the user to excite.The similar part that it and circle-elder generation and circle-back stroke characterizes incident is that stroke to be deleted is by the border stroke indication of predetermined number.An example of the process of the deletion event that system of the present invention can provide has been shown among Figure 12.As shown in figure 12, during the surveillance input (1200), deletion event may be detected (1210).Deletion event is recorded (1220) then, and the prompting user provides the border stroke (1230) in indication zone to be deleted.Then, the stroke that this system can recording scheduled number, this prompting is eliminated (1250) then.

So stroke that reflection takes place by the user can take place and write down and by the data stream of the automatic event of system in system of the present invention.Preferably use in many compression algorithms of knowing one or more that data stream is compressed to reduce the required storage space of data stream.The stroke that all right recording user of system causes characterizes incident, and these incidents can be provided with linearity, circle-back or circle-first pattern by the user.But this system is the deletion event that excites of recording user also.System will reflect the data stream that stroke and incident take place by the sequence of event that they take place.

III. Be used to handle the exemplary embodiment of record data
