ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
This invention relates generally to optical readers. In one aspect, it relates to a method for using an optical reader to automatically direct a computer to retrieve and display information from a remote location on a network.
BACKGROUND OF THE INVENTION
With the growing numbers of computer users connecting to the “Internet,” many companies are seeking the substantial commercial opportunities presented by such a large user base. For example, one technology which exists allows a television (“TV”) signal to trigger a computer response in which the consumer will be guided to a personalized web page. The source of the triggering signal may be a TV, video tape recorder, or radio. For example, if a viewer is watching a TV program in which an advertiser offers viewer voting, the advertiser may transmit a unique signal within the television signal which controls a program known as a “browser” on the viewer's computer to automatically display the advertiser's web page. The viewer then simply makes a selection which is then transmitted back to the advertiser.
In order to provide the viewer with the capability of responding to a wide variety of companies using this technology, a database of company information and Uniform Resource Locator (“URL”) codes is necessarily maintained in the viewer's computer, requiring continuous updates. URLs are short strings of data that identify resources on the Internet: documents, images, downloadable files, services, electronic mailboxes, and other resources. URLs make resources available under a variety of naming schemes and access methods such as HTTP, FTP, and Internet mail, addressable in the same simple way. URLs reduce the tedium of “login to this server, then issue this magic command . . . ” down to a single click. The Internet uses URLs to specify the location of files on other servers. A URL includes the type of resource being accessed (e.g., Web, gopher, FTP), the address of the server, and the location of the file. The URL can point to any file on any networked computer. Current technology requires the viewer to perform periodic updates to obtain the most current URL database. This aspect of the current technology is cumbersome since the update process requires downloading information to the viewer's computer. Moreover, the likelihood for error in performing the update, and the necessity of redoing the update in the event of a later computer crash, further complicates the process. Additionally, current technologies are limited in the number of companies which may be stored in the database. This is a significant limitation since world-wide access presented by the Internet and the increasing number of companies connecting to perform on-line E-commerce necessitates a large database.
Many types of optical readers are known, however, their cost and complexity have heretofore limited their use primarily to industrial and commercial users. Now, many new network-based technologies are being developed for home users which involve optical scanning. Thus, the need for a simple, low cost optical reader which can be attached to a personal computer has emerged.
SUMMARY OF THE INVENTION
The present invention disclosed and claimed herein comprises, in one aspect thereof, a method of accessing a remote location on a network using an optical reader. The optical reader includes an optical scanning system, a programmable memory system and an output circuit and is user-switchable between a scan mode, a record mode and a playback mode. The optical reader transmits a code to a first computer disposed on the network. When the optical reader is in the scan mode, the code is indicative of information extracted from an encoded indicia just scanned by the optical scanning system. When the optical reader is in the playback mode, the code is indicative of information retrieved from a user-selectable memory in the programmable memory system. The information in the user-selectable memory was previously stored in the user-selectable memory after being extracted from an encoded indicia scanned by the optical scanning system when the reader was in the record mode. In response to the first computer receiving the code from the optical reader, a second computer disposed on the network is accessed. A lookup operation is performed at the second computer to match the code received from the optical reader with a routing information for a remote location on the network. The routing information is returned from the second computer to the first computer. The remote location on the network is then accessed in accordance with the routing information returned from the second computer.
