Definitions
- the present invention relates to a method in a mobile telephone system and methods m a mobile station.
- the invention also relates to an arrangement in a mobile telephone system and arrangements m a mobile station.
- the invention also relates to a method for processing an information object which contains a graphical representation of a handwritten message and a storage medium for digital information.
- SMS Short Message Service
- An SMS message can also be sent from a perso- nal computer via an SMS server to a mobile station or m the opposite direction m the form of an e-mail message.
- a receiving mobile station does not need to be switched on when the message is sent, the message can be stored m the mobile telephone system until the mobile station is connected.
- GSM Global System for Mobile communications
- the transfer of handwritten messages produced by digital means is also made possible.
- the text messages can thus be made more individual.
- characters which are known by the sender and the receiver, can be transmitted even if the mobile stations and the intermediate system/systems are not adapted for such characters. For example, Japanese characters can be sent by mobile stations adapted for the Latin alphabet.
- a difficulty associated with the transfer of such a message is that the displays of the mobile stations are often relatively small. This usually makes it impossible to show a complete file, for example in GIF format.
- a message which contains a digital graphical representation of a handwritten message of some length and recorded with some resolution, will normally be many times larger than the display of the receiving mobile station. It can also be assumed that a handwritten message will be written sparsely with respect to the surface area, compared with a message of the SMS type. A conceivable possibility of showing the message is to reduce it in size until it can fit into the display of the mobile station.
- One problem with such a method is that the resolution in the display of most mobile sta- tions is so low that most of the messages would be unreadable, especially if the sender has a dense handwriting.
- Another conceivable method is to show only a small part of the image file and allow the receiver to step on, up/down/to the right/to the left through the image with the keys of the mobile station.
- this is difficult and cumbersome.
- the message is oriented horizontally in the image, it may well be written diagonally m the image file. If this is so, the displaying of the message will be even more complicated. If the receiver steps through the image, there is also a risk that some of the message will be bypassed, for example if it is positioned down m one corner.
- This object is achieved by means of a method m a mobile telephone system according to claim 1 and a corresponding arrangement according to claim 8; a method m a receiving mobile station according to claim 6 and a corresponding arrangement according to claim 9; and a method m a transmitting mobile station according to claim 7 and a corresponding arrangement according to claim 10.
- the object is also achieved by means of a method for processing a primary information object according to claim 11 and a digital storage medium contain- ing a computer program according to claim 12.
- a method is provided in a mobile telephone system where a node, connected to the system, is adapted to forward incoming primary information objects, such as files, to a mobile station which is wirelessly connected to the system.
- primary information object which contains a graphical representation of a handwritten message
- the mobile telephone system identifies display characteristics of the receiving mobile station. After that, image areas m the primary information object are identified, with a size based on the identified display characteristics, the areas containing parts of the message These image areas are then placed m one or more secondary information objects, such as files, after which the secondary information object/objects is/are transferred to the mobile station.
- the mobile station can now show parts of the transmitted message, which is just the right size.
- the result is that the message can be shown with good resolution and with only a small number of, or perhaps no, button depressions.
- a diagonally written message can be shown with an orientation, which is correct for the mobile station.
- the identification of display characteristics preferably comprises the following steps: transmitting of a request for display characteristics to the mobile station, and receiving information about display characteristics from the mobile station. This enables the method to be carried out even if the hardware identity of the receiving station is unknown to the system.
- the identification of display characteristics comprises the following steps: obtaining a hardware-identif ing identity number relating to the mobile station, and utilizing a lookup table for obtaining, with the identity number as input data, mfor- mation about the display characteristics. This enables the method to be carried out without previous communication with the mobile station.
- the content of the primary information object is preferably produced by displacing an optical sensor in relation to a position-coding pattern, the sensor being adapted to detect absolute positions m the pattern. This enables utilization of a very large input area.
- a method in a mobile station communicating with a mobile telephone system, the mobile station receiving information from the telephone system.
- the method is then characterized by the following steps, when the first incoming primary information object contains a graphical representation of a handwritten message; identifying image areas, with a size based on display characteristics of the mobile station, m the first incoming primary information object, the image areas containing parts of the message, and showing at least one of the image areas m a display of the mobile station.
- a method is provided m the first mobile station communi- eating with a mobile telephone system, the first mobile station sending information via the mobile telephone system.
- a first primary information object is intended to be transmitted to a second mobile station via the mobile telephone system.
- the method is characterized, when the first primary information object contains a graphical representation of a handwritten message, by the following steps: requesting display characteristics of the second mobile station; identifying image areas, with a size based on the display characteristics, m the first mfor- mation object, the image areas containing parts of the message; creating at least one secondary information object containing at least one of the image areas; and con- veymg the secondary information object to the second mobile station.
- This aspect of the invention also corresponds to an arrangement and can be varied to a large extent like the first aspect.
- a method for processing a primary information object comprises the following steps, when the primary information object contains a graphical represen- tation of a handwritten message: identifying image areas in the primary information object, the size of the image areas being based on display characteristics of a display on which the message is intended to be shown, and the image areas containing parts of the message; creating at least one secondary image object containing at least one of the image areas.
- This method can be utilized, for example, m a personal computer, which intends to send a handwritten message to a mobile station and has then advantages as described above.
- a storage medium for digital information is provided which is readable by a computer system.
- the storage medium contains a program for processing a primary information object, which defines the following steps, the primary m- formation object containing a graphical representation of a handwritten message: identifying image areas m the primary information object, with a size based on display characteristics of a display on which the message is m- tended to be shown, and the image areas containing parts of the message; creating at least one secondary information object containing at least one of the image areas.
- This software can be utilized, for example, in a personal computer, which intends to send a handwritten message to a mobile station and has then advantages as described above . Brief Description of the Drawings
