Definitions

  • a user who has to select one of a number of prestored (canned) messages in response to a received message has a limited number of responses because the selective call receiver can store only a limited number of messages. Additionally, providing the option for a user entered response via a key pad on a selective call receiver is awkward and cumbersome because selective call receivers are miniature devices that can have only a limited number of small keys or buttons that proves to be difficult to manipulate because of their small sizes.
  • FIG. 9 is a flow diagram of the writing recognition process of the embodiment of FIG. 8.
  • the selective call receiver 100 comprises a digitizer 404 similar to the digitizers 304 of FIG. 3, except that the digitizer 404 is positioned, located or formed into a part of the display or screen 402 as shown in FIG. 2.
  • the selective call system 500 comprises a base site 530 which has a terminal/controller 532 coupled to an antenna tower 534 for receiving messages and transmitting selective call messages.
  • the base site 530 transmits selective call messages to a selective call receiver 100 which comprises an antenna 502 for intercepting transmitted radio frequency (RF) signals which is coupled to the input of a receiver 504.
  • the receiver 504 provides for reception of transmissions on a single reception frequency or reception on multiple reception frequencies in a manner well known to one of ordinary skill in the art.
  • the selective call receiver has a transmitter which comprises an acoustic transmitter 526 or an Infra Red (IR) transmitter 526 for downloading a message (handwritting characters) associated with the readable characters to a communicating device, such as telephone or computer, that has a corresponding acoustic or IR receiver to receive the downloaded message.
  • a communicating device such as telephone or computer
  • the user selects one of the stored response to be transmitted in response to the received selective call message or generate a response by selectively pressing the keys of the selector switches 520 to generate a message response.
  • the user preferably uses the stylus 108 to write handwritten characters on the digitizer 104.
  • the battery saver operation is controlled by the CPU 610.
  • the battery saving signals are directed over the data bus 608 to the I/O port 612 which couples to the power switch 510 (FIG. 5).
  • Power is periodically supplied to the receiver to enable decoding of the received selective call receiver address signals and the selective call messages which are directed to the selective call receiver 100.
  • a recognition engine 622 that has a comparator 624 and a memory, a decoder 626 and a corrector 628 are used to generate readable characters from the handwritten characters entered on the digitizer 104 and a encoder 630 is used to encode the handwritten message in a paging message or response to be transmitted to the base site 530.
  • the selective call receiver 100 uses the encoder 630 to encode the stored message with an address to compose an ack-back response or paging signal, step 726 which is transmitted in response to the receipt of a page (selective call message), step 728.
  • the message can also be stored as profile information to associate with other subscriber information of the paging system.
  • the handwritten message can include a paging subscriber's address and name which can be stored.

Abstract

Récepteur d'appels sélectif (100) qui reçoit, décode et met en mémoire des messages d'appel sélectifs et comporte un numériseur (104) acceptant les caractères manuscrits et un moteur de reconnaissance (622), couplé au numériseur (104), qui génère des caractères lisibles à partir de caractères manuscrits. Une mémoire (604) couplée au moteur de reconnaissance (622) stocke les caractères lisibles. Un décodeur (626) couplé à la mémoire (604) associe les caractères lisibles aux messages d'appels sélectifs et un afficheur (102) couplé à la mémoire (604) et au décodeur (626) affiche un message avec des caractères lisibles associés audit message.
