  • the present invention relates to a system in which an electronic reading device, such as an electronic pen, an electronic mouse, or a hand scanner, works in cooperation with an address pattern (e.g., a specially formatted pap L I to provide for a detection of a location of the electronic reading device over the address pattern.
  • an address pattern e.g., a specially formatted pap L I to provide for a detection of a location of the electronic reading device over the address pattern.
  • a pattern of dots can be defined such that, by examining a very small portion of the pattern, a precise location in the overall pattern can be determined.
  • the pen can detect its position (e.g. , using a built m camera) by detecting a 3 mm by 3 mm portion of the pattern. By taking approximately 100 pictures per second, the pen is capable of determining its exact position to within 0.1 mm or less.
  • This system can be used to provide user input, to facilitate user interaction, or to store handwritten notes or drawings.
  • by associating portions of the overall pattern with certain applications such a system can be used to interact with wide variety of applications.
  • the electronic pen includes an ink cartridge and is capable of writing in a typical fashion.
  • the electronic pen 10 includes some type of sensor (e.g., a built-in camera or optical detector) that is used for detecting an address pattern on a specially formatted piece of paper 12.
  • the paper 12 is formatted with a small portion of a large address pattern (i.e., a portion of the address pattern is printed on the paper 12) such that when the electronic pen 10 is used to write on or otherwise make marks on the paper 12, the writings or markings can be electronically detected and stored.
  • the paper 12 might constitute a form that can be used for sending an e-mail.
  • the paper 12 might include a space for writing in the e-mail address of an intended recipient, a space for writing a subject of the e- mail, and a space for writing the body of the e-mail.
  • the position and movement of the electronic pen 10 on the paper 12 can be determined by repeatedly detecting the current x, y coordinates of the pen 10 (e.g., at rate of 100 frames per second) .
  • the markings can then be converted into ASCII text using an appropriate handwriting recognition program.
  • the e-mail can be sent, for example, by checking a send box at a predetermined location on the paper 12.
  • the coordinate information collected by the pen 10 is sent by a short range radio transmitter in the electronic pen 10 to a nearby mobile station 14 using a short range radio interface 16 such as a local wireless radio link (e.g., a local wireless radio link supported by Ericsson's BluetoothTM wireless communications technology) .
  • a local wireless radio link e.g., a local wireless radio link supported by Ericsson's BluetoothTM wireless communications technology
  • the coordinate information could also be sent to, for instance, a desktop or portable computer, a personal digital assistant (PDA), a television, or a Bluetooth terminal.
  • PDA personal digital assistant
  • a local wireless radio link other types of local wireless links, such as Global System for Mobile Communication (GSM), such as inductive coupling and infrared light; other types of radio links; or wired transmission media, such as a cable can also be used.

Abstract

L'invention concerne un procédé et un système permettant d'entrer des données électroniques à l'aide d'un dispositif de lecture électronique qui détecte au moins une position du dispositif de lecture électronique par rapport au motif d'une adresse prédéfinie d'une surface spécialement formatée. Les données concernant cette position détectée au moins sont transmises, de préférence, via une interface sans fil à l'aide d'un émetteur-récepteur radio. Les données sont reçues par un dispositif électronique séparé qui effectue une opération à l'aide des données reçues. L'opération correspond à une zone sur le motif de l'adresse qui contient au moins une position détectée. L'opération peut, par exemple, consister à initier une fonction d'hyperlien.
