Definitions

  • the present invention relates to hand-held units for recording handwritten information.
  • handwritten information there are a number of ways to communicate handwritten information electronically.
  • One alternative is to write the information on a sheet of paper and thereafter to send the information via a fax machine.
  • An alternative way of sending handwritten information electronically is to scan it in and to send it electronically via, for example, electronic mail or using the mobile telephone network.
  • a disadvantage of both methods is that two steps are required to enter the handwritten text electronically. In a first step the user writes the text on a base and in a second step the handwritten text is converted into electronic format via optical reading in the scanner or the fax machine.
  • a user unit of the type described in said WO documents has a memory in which the information that has been recorded by the user unit is stored.
  • the user unit can be arranged to send information by wireless means to, for example, a mobile telephone or a personal computer, from which the information is forwarded to the correct recipient, typically via an information management unit in the form of a network server or the like.
  • An example of information that can be recorded by the user unit is a handwritten message, a signature or a handwritten address on a form. In several cases, it can be advantageous to save the information recorded by the user unit for use at a later occasion.
  • a user unit for recording handwritten information is advantageously hand-held and is a typical home electronics product. In order to keep the price of the product down, this is therefore provided with a relatively small internal memory unit.
  • An object of the present invention is to overcome the above problem at least partially.
  • the present invention aims to provide a hand-held user unit for writing down and recording handwritten information, which allows the user to send the recorded information to a recipient at any time after it was written down.
  • Another object of the invention is to describe a technology that makes it possible to keep down the pro- duction cost for such a hand-held user unit.
  • Another object is to overcome the above problem without the need to make changes to the user's behaviour or to the equipment communicating with the user unit .
  • An additional object is also to describe a techno- logy that enables the user to reduce the cost of sending the handwritten information to a recipient.
  • the user unit also contains a means that records electronically the information that is written down by means of the user unit. This recording preferably takes place at the same -time as the information is written down.
  • This can be carried out in a plurality of different ways within the scope of prior art, such as via accelero- meters and/or gyroscopes, via triangulation equipment, via mechanical movement detection (trackball or the like) , via interference analysis on the basis of laser light emitted and reflected from a base, etc.
  • the recording means to comprise an image sensor for recording, preferably optically, an absolute position code on a base. As a result, it is possible to connect the functionality to the absolute positions that are coded on the base, as described in
  • This configuration is, for example, relevant in a mobile embodiment, where the information is transferred from the internal memory to the external memory at least partially via a mobile telephone network.
  • the user unit can be configured to transfer the information only when it is in contact with the computer network, so that the information is transferred at minimal cost .
  • the user unit can be configured to transfer information when the information transmission means has access to a given bandwidth.
  • the user can also prioritise between different types of information, so that certain information is transferred as soon as possible, while other information is transferred at minimal cost. For example, the user can indicate such prioritisation at the time of writing, for example by marking a selection box on the base or by activating a switch on the user unit.
  • the transmission is configured for minimal user disturbance, for example by the transmission being carried out latently when the user unit is being switched off, when the user unit is being placed in a given position, or when a switched-on user unit has not recorded any new information for a given period of time.
  • the above examples of rules can also be combined.
  • the user unit From the point of view of the user unit, it can be advantageous to have a rule that information is transfer- red from the internal memory unit when this has attained a given level of fullness.
  • This rule is simple to implement and secures the efficaciousness of the user unit.
  • the information can be transferred in accordance with a FIFO principle (First In, First Out) , or in accordance with some other suitable algorithm.
  • the level of fullness can in this connection correspond to an amount of memory occupied in the internal memory unit .
  • dynamic compression that is when the internal memory unit is permitted to become completely full and the informa- tion stored therein is thereafter further compressed as more information is added, the level of fullness can correspond to a degree of compression.
  • the above-mentioned information transmission means can be realised in the form of a combination of software, which is executed in a processor in the user unit, and a communication unit, for example for direct connection to a computer network or mobile telephone network, or for wireless short-range communication with an external network connection unit such as a mobile telephone, a PDA or a personal computer.
  • the communication unit can alterna- tively be designed for wired communication.
  • the information transmission means is arranged to carry out exclusively one-way transmission of information from the first to the second memory unit.
  • This embodiment minimises the flow of information between the memory units, which is particularly advantageous when the communication link between the memory units is expensive and/or has low ⁇ ⁇ tsJ M l- 1 I- 1
  • the information can, for example, be time-stamped at the time of recording, in order to facilitate searching in the external memory unit .
  • the transmission of information is preferable for the transmission of information to be initiated via a "send" command from the user unit.
  • the "send” command initiates the transmission of asso- ciated information from the internal memory unit to the external memory unit, and collation of associated information in connection to the external memory unit.
  • the recorded information comprises a plurality of absolute positions that form an electronic version of the handwritten information.
  • the information can, in this case, be recorded from a base with an absolute position code, as mentioned above .
  • the hand-held user unit After recording the "send" command, the hand-held user unit is preferably arranged to obtain an address for the information management unit by a request to an external look-up unit and on the basis of the position content in the recorded information.
  • the position content in the recorded information controls where the information is to be sent for further processing, which increases the possibilities for, and simplifies, communication and management of handwritten information.
