Method and apparatus for wireless remote information retrieval and pen-based data entry
First Claim
1. A system for wireless remote information retrieval and pen-based data entry, comprising:
- a) a central computer system having memory means containing a plurality of digitally stored forms and for storing data;
b) a wireless network coupled to said central computer system, said wireless network including at least one transceiver;
c) at least one portable pen-based computer having a position sensitive display, a stylus for writing on said position sensitive display, and a wireless communication means for communicating with said wireless network through said at least one transceiver;
d) interface means defining areas on said position sensitive display responsive to said stylus for selecting one of said plurality of digitally stored forms for display on said position sensitive display;
whereinupon selection of one of said plurality of digitally stored forms, said one of said plurality of digitally stored forms is transmitted by said central computer system to said pen-based computer through said wireless network and is displayed on said position sensitive display,handwriting written on said position sensitive display with said stylus is transmitted to said central computer system through said wireless network as electronic ink, andsaid central computer system associates said electronic ink with said one of said plurality of digitally stored forms by creating an association reference code and stores said electronic ink with said association reference code in said memory means for storing data without duplicating said one of said plurality of digitally stored forms so that said electronic ink and said association reference code are stored together with each other, but separate from said one of said plurality of digitally stored forms.

Abstract
A method and system for wireless remote information retrieval and pen-based data entry includes a central computer system having a relatively large storage capacity and/or access to relatively large storage devices and coupled to a wireless network having a plurality of cells. One or more portable pen-based computers are provided with wireless communication capability for connecting with the central computer system through the wireless network. The central computer system is provided with software for accessing a plurality of digitally stored forms and transmitting those forms to the pen-based computers in response to selection requests from the pen-based computers. A selected form is displayed on the screen of the pen-based computer which requested it and data is entered through the pen-based computer by handwriting on the display of the form. The central computer system receives the hand written data as electronic ink and associates the electronic ink file with the form upon which it was written. The form and its associated electronic ink file are stored in the central computer system or in a storage device to which the central computer system has access. The hand written data entered through the pen-based computer is thus associated with other data which can be recalled and/or associated with yet other data without recognizing the handwritten data as text.
