Definitions

• This invention concerns an arrangement for providing an electronic information service and a corresponding method.
• a large number of interactive information services are offered to users wno are connected to the Internet . These web services give users the ability to read mfor- mation which is written into the service by other users and also to enter information themselves, for example as a contribution on a matter or as a comment on a previous contribution submitted by another user.
• BBSs so-called "chat" web pages.
• chat web pages.
• messages are continuously contributed by users if the service is frequently visited. The most recently contributed message is added at the bottom of the service ' s page and earlier messages are scrolled upwards on the screen.
• users can have a written conversation m real time.
• Web pages of the "cnat" type, below called chat pages have become very popular, even though they have a number of limitations. If new contributions come m at a fast rate, the earlier contributions scroll quickly out of sight. This can make it difficult to follow a conversation on the chat page. It can also be difficult to tell which of the earlier contributions a later contribution is commenting on, even tnough a note to this effect can be made at the start of the later contribution. This is because there can be several other contributions between a contribution making a comment and the contribution to which the comment is referring. If a chat page is very busy a conversation on it can be very difficult to follow. Certain web sites therefore now offer a number of so-called “cnatrooms", that is cnat pages for users with particular interests or within par- ticular age groups. This reduces the load on each individual chat page, as the users can be spread out.
• chat pages are based on written text and are therefore principally a verbal means for expression.
• non-verbal symbol comDinations for example ":-)" or “:-(" to indicate moods and the like.
• This invention aims to eliminate the apove-mentioned limitations either completely or partly.
• Th s aim is achieved by an arrangement for providing an information service m a computer system according to claims 1 and 12, and by the corresponding method according to claims 11 and 14.
• the arrangement aims to provide an electronic information service m a computer system, which is connected to a network.
• a plu- ralicy of users can enter information into and read information from the electronic information service m the computer system via the network.
• the arrangement is characterized by means for creating a first information object comprising a partial area of a virtual pixel area.
• the pixel area contains information entered by users from among the above-mentioned plurality of users.
• means for transmitting the first information object via the network to a first of the above-mentioned number of users means for receiving a second information object from the first user corresponding to at least part of the above-mentioned partial area of the virtual pixel area, and means for updating the virtual pixel area utilizing the received information object.
• a user can tnus download a certain part of the pixel area, read the messages on this partial area and add his own message to it. Then the user can resubmit cms modified partial area, after which the pixel area is updated by the added messages .
• messages can ne inserted m selectable positions on the pixel area.
• the messages are not moved, but can remain m the same place on the area. It is therefore easier for a user to relate his message to an earlier message, by placing the message next to it. It is also much easier to follow a conversation, as messages not connected with the conversation can be placed elsewhere on the pixel area.
• the information service can, if required, be released from text format, which means that more expressive messages can be submitted.
• figures of various types can be included.
• the virtual pixel area contains a position-coding pattern.
• the means for creating the first information object can also add a position-coding pattern to this. This allows the user after printing out the selected partial area to write a message using a drawing device, which uses a position-coded base, that is a base, provided witn a position-coding pattern.
• a position-coding pattern can be designed m the way described m the Applicant's Patent Applications WO 00/73983 and PCT/SE00/01667 , which are hereby incorporated by reference.
• a drawing device can thus comprise a pen which deposits ink on the base while at the same time an optical sensor detects positions on the base.
• the means for creating the first information object preferably also comprises means for receiving a request from the first user concerning the transmission of a particular partial area of the virtual area. This partial area is inserted into the information object. This allows the user to read and write messages anywhere on the area.
• the virtual pixel area contains a background image.
• t ⁇ e means for creating the first information object can also add a background image to this. This makes it easier for the user to orientate himself on the area.
• the virtual pixel area can consist of a graphical file. However, the area consists preferably of a number of graphical files, which allows very large total pixel areas to be used m an effective way.
• the means for creating a first information object preferably also adds an information image to this information object. This makes it possible for the system to transmit, for example, advertisements to the user, which can be used as a source of income.
• the information image is preferably selected based on user parameters, specific to the first user and available to the computer system.
• cne computer system also comprises means for notifying a second user when a partial area of the pixel area has been updated. This makes it possible for a user to be kept _.p to date with what is written within a particular partial area without any effort on his part .
• an arrangement and a corresponding method m a computer system, which is connected to a network where the system comprises an electronic information service. Users can enter messages into and read messages from the electronic information service via the network.
• the arrangement is characterized m that the service comprises a virtual area consisting of a matrix of pixels which is at least two-dimensional, and means for receiving a message from a user, means for receiving a position indication associated with the message from the user and means for placing the message m a position on the area, which position is determined by the position indication.
• the arrangement also comprises means for removing messages after a particular period of time. This prevents the information service being filled up so that new messages cannot be entered.
• FIG. 1 illustrates diagrammatically an arrangement in a computer system in accordance with the invention.
• Fig. 2 shows the work of an arrangement m a computer system of the type shown in Fig. 1.
• Fig. 3 shows the work of a simplified form cf an arrangement in a computer system in accordance with the invention .
• Fig. 4 shows preferred embodiments of a virtual pixel area in accordance with the invention.
• Fig. 5 shows the function of a preferred form of the invention, where position coding is used.
• Fig. 1 illustrates diagrammatically an arrangement in a computer system 1 in accordance with the invention.
• the computer system 1 is connected via the Internet 3 to the personal computers 5 of a number of users . These users can communicate with the computer system 1 and are allowed both to read and write information in an electronic information service 7 in the computer system 1.
• the information service 7 is designed as a virtual pixel area 9, which will be described below in greater detail.
• the pixel area 9 consists in its simplest form of a two- dimensional matrix of pixels 11 which can assume at least two states, "one" / "black” or " zero" / "white” .
• the size of the pixel area 9 is preferably considerably larger than the pixel area of a normal computer monitor screen.
• the size can, for example, be 10000*10000 pixels, but can also be much larger.
• a user equipped with a normal per- sonal computer 5 can thus only see a small part of the pixel area 9 at a time m full resolution.
• the large format of the pixel area 9 allows room, however, for a large number of messages 13 of varies kinds at any particular time .
• a user who uses the service can ask to view various partial areas m various resolutions. Thus a user can, for example, start a session by viewing the whole area at very low resolution. The messages, which are entered on the area, will then probably net be legible. Instead the areas with messages will appear as darker regions m the image which the user sees.
• a pixel on the user's screen will represent perhaps an average of hundreds of pixels on the virtual area.
• the user can then mark a smaller part of the area, which he wants to look at more closely.
• a request is then sent to the computer system, which creates and retransmits a new file with the content of this area.
• the user can also jump around m the area, for example using the arrow keys on nis personal computer, until he finds a place on the area where he wants to write a message.
• the system preferably only permits writing m images shown in the highest resolution, that is when there is a one-to-one relationship between pixels m the computer system's virtual pixel area and pixels m the image which is shown on the user's personal computer.
• a background image is preferably achieved, for example m the form of a map on the pixel area, m order to make it easier for the user to orientate himself on the area. This also produces intuitive "chatrooms", for example a district, a city or a mountain range.
• Fig. 2 shows the work 21 of an arrangement m a computer system 1 of the type shown m Fig. 1 and with reference also to this Figure.
• a request is received from a user via the network 3 for tne transmission of a particular part of the virtual pixel area 9.
• the computer system 1 is provided with means for receiving this request.
• the computer system is meant m general software, which contains program steps, which cause the system to perform certain operations.
• the arrangement also comprises means for creating m a second step 25 an information object 17 in tne form of a file which contains a copy 15 ' of the requested partial area 15 of the virtual pixel area 9 of the computer system 1.
• the created file 17 can have various formats. The simplest form consists of a copy of the requested partial area of the virtual pixel area. If a partial area of the pixel area has been requested which is larger than the users monitor screen can display m full resolution, the system can handle this m various ways.
• the partial area can either be incorporated m its existing state m the created information object 17 or the resolution of the image area can be reduced so that it can be displayed m its entirety on the monitor screen of the user making the request. In the first case the user can instead choose to display different parts of the image area, for example by using the arrow keys on his personal computer 5.
• a superimpose ⁇ position-coding pattern and/or a background image can be added. Alternatively these can be incorporated m the virtual pixel area. The use of the pixel area and background image will be described m greater detail below.
• an information image 19 is added to the created information object 17. This can also be superimposed, but it is preferably combined with the copy 15' of the requested partial area 15 to form a composite image comprising two partial areas.
• the added information image 19 can preferably consist of an advertising message or other information, which the owner of the computer system 1 wants to transmit to the user.
• the information image can preferably be selected based on parameters specific to the user, for example his age, hobbies, etc. It is assumed that such parameters are available to tne computer system 1.
• a fifth step 31 the system 1 transmits tne created information object 17 to the user via the network 3.
• the user can then read the message written in the re- quested partial area and the text and diagrams m the added information image.
• the user can also add information himself using various input devices. This can either be carried out m a copy of the transmitted information object or can oe carried out directly m the same.
• the added information can consist of text or figures.
• an information object is sent back to the com- puter system. It can be the information object, which the user received, and m which he has made changes or it car- be a new information object generated based on this. It is only necessary to resend the part of the partial area 15 transmitted to the user m which the user has made changes.
• the computer system thus receives a second information object from the user m a sixth step 33.
• the received object also contains an indication of which partial area of the virtual pixel area the received object con- cerns, that is tne location of the received partial area m the pixel area.
• the computer system updates the virtual pixel area 9 m a seventh step 35 using the received information object, so that the user's added message can be read by other users of the system.
• the computer system notifies another user that a partial area, which this user wanted to monitor, has been updated.
• Fig. 3 shows the work 41 of a simplified form of an arrangement in a computer system according to the invention. Also here the invention comprises a virtual pixel area.
• a message is received from a user.
• an indication is received m the form of a position indication of wnere on the virtual pixel area the user wants the received message to be placed. The order of these two steps can be reversed.
• the message is placed m the location on the virtual pixel area indicated by tne position indication.
• Fig. 4 shows preferred embodiments of a virtual pixel area 51 according to the invention.
• the area consists preferably of a number of files 53, 53', 53", etc, stored on a digital storage medium m the computer system.
• Each file consists of a preferacly two-dimensional matrix of pixels 55.
• each pixel can assume the value "one" and the value "zero", corresponding to black and white when a partial area of the pixel area is displayed.
• the pixels can, however, preferably assume more values and can thereby oe made to represent colors and gray scales .
• Each pixel can also be given a time value, that is the time when tne value of the pixel was last changed by writing a message.
• the virtual pixel area can also consist of a matrix m more than two dimensions, whereby several layers can be achieved.
• One layer can then contain a background image, which is dis- played to the users who, however, are not able to write information m this layer. Instead tne users can write information m a drawing layer which is superimposed en the background layer when Cms is displayed.
• the advantage of letting the virtual area 51 consist of a number of graphical files 53, 53', 53", is that only a set of small files need to oe updated when a user adds information, instead of a very large file having to be updated.
• For updating a partial area 57 of the virtual area normally only one to four files (53', 53") are updated, even though the pixel area perhaps consists of hundreds of files. In this way very large pixel areas can Joe used without an updating cf the area taking a very long time.
• a transmitted partial area is normally much smaller than the virtual pixel area.
• the file format of the pixel area can be a compress- ed graphical format, for example of the type .jpg or
• m a non-compressed format, for example of the type .bmp or .tiff.
• the advantage of this is that non-compressed files are quicker to open for editing when updating the pixel area.
• m compressing these files as they are not transmitted over narrow-oand channels.
• the information objects (17, Fig. 1) wnich are created at the request of the user out of a partial area of the virtual area can, on the other hand, preferably consist of com- pressed files as these are transmitted over the computer network (3, Fig. 1) .
• Fig. 5 shows the function of a preferred form of the invention where position coding is used.
• the pixel area 61 contains a position-coding pattern 63, preferably m a separate layer.
• this pattern can be superimposed on the partial area 65 of the system' s pixel area 61 which a user selects, when the information object is created which is intended to be transmitted to the user.
• this pattern can be added by an application m the personal computer 67 used by the user.
• the position-coding pattern 63 can advantageously be of such a type as shown m the Applicant's Patent Applications WO 00/73983 and
• PCT/SE00/01667 where each position is encoded by a number of symbols and where one symbol is used to encode a number of positions.
• the position-coding pattern 63 shown is constructed as shown m WO 00/73983, where a large dot represents a "one" and a small dot represents a "zero". It is, however, also possible to design the position-coding pattern 7 as described m PCT/3 ⁇ 00/01667 , where different displacements of a dot m relation to a raster point encode different symbol values.
• a drawing device 71 is arranged to detect positions on the p ⁇ nted-out area 69 utilizing the position-coding pattern 63.
• the drawing device 71 When the drawing device 71 is move ⁇ relative to the area 69 and m contact with this, the drawing device 71 records a series of positions on the area 69, which series is transmitted to the user's personal computer 67.
• the transmission of the position information can be carried out using various types of cable or by means of an infrared link. However, a short-range radio link is preferably used, for example in accordance with the BLUETOOTH standard.
• the position information can be transmitted as a set of pairs of co-ordinates, but preferably the drawing device first converts the series of pairs of co-ordinates into a polygon tram whicn is then transmitted. When the user draws on the pr ted-out area 71, what was drawn can therefore be recorded by an application m the user's personal computer 67.
• the records 73 which are made, can then be used to update the virtual pixel area 61 m the information service as shown above .
• the user can map a position-coded base he already has his possession against a partial area that he has downloaded. Thereafter mes- sages can be added to a partial area, which has been downloaded by writing on the base with a drawing device such as that described above.
