Information retrieval and presentation systems with direct access to retrievable items of information
First Claim
Patent Images
1. An information retrieval and display system which can be employed in a learn-then-perform mode of operation, said system comprising a module which has:
- (a) a data reader for reading data from an encoded data storage device, and (b) a screen for displaying information generated from data read from said data storage device;
said data storage device having means for storing in digital form data corresponding to;
(a) a multiple choice menu, and (b) an item of information which can be retrieved from the data storage device by making a choice from said menu; and
said system further comprising;
a directory means for providing direct access to said item of information, said directory means being separate from and physically independent of said module and including an identifying code and a descriptor for each menu choice corresponding to an item of retrievable information; and
control means having means for so controlling the operation of the data reader as to cause data representing a selected item of information to be retrieved from said data storage means and the item of information generated from said data presented on said screen when said data reader is activated by the identifying code for the menu choice to which the selected item of information corresponds, said control means also having control elements which are activatable by a system user to generate said identifier code.

Abstract
Systems (or appliances) which have a learn-then-perform mode of operation. Information is stored in digital form by a data storage device and is retrieved for presentation by: (a) navigating through a hierarchial array of multiple choice menus, or (b) directly and in one fast step by employing identifier codes associated on a one-to-one basis with retrievable items of information. Identifying codes may be obtained as needed from a directory in which each code is associated with a descriptor of the corresponding item of information.

10. An information retrieval and display system which can be employed in a learn-then-perform mode of operation, said system comprising a module which has:
- (a) a data reader for an encoded data storage device, and (b) a screen for displaying information generated from data retrieved from said data storage device;
said data storage device having means for storing in digital form data corresponding to;
(a) a multiple choice menu; and
(b) an item of information which can be retrieved from the data storage device by a system user making a choice from said menu, said system further comprising;(a) a directory means which is separate from and physically independent of said module, and (b) control means having means which, upon said choice being made;
(c) causes said data reader to read data identified by said choice from the storage device, and (d) causes said item of information to be generated from said data and presented on said screen;said directory means including a different, multi-digit numerical identifying code and descriptor for each menu choice corresponding to an item of retrievable information; and said control means comprising;
(a) control elements which are activatable by said system user to generate signals representing the distinct identifier code for the user selected item of information, (b) buffer means for storing said signals in the order in which they are generated, and (c) means for identifying the last in the series of those signals representing the identifier code and then retrieving the signals from said buffer in the order in which they were stored in said buffer and activating said data reader to retrieve from said storage device the data from which the selected item of information can be generated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 19, 20)

18. An information retrieval and display system which can be employed in a learn-then-perform mode of operation, said system comprising a module which has:
- (a) a data reader for an encoded data storage device, and (b) a screen for displaying information generated from data retrieved from said data storage device;
said data storage device having means for storing in digital form data corresponding to;
(a) a multiple choice menu means; and
(b) first and second items of information which can be retrieved from the data storage device by a system user making choices from said menu means; andsaid system further comprising;
(a) a directory means which is separate from and physically independent of said module; and
(b) control means having means which, upon a choice being made from said menu means;
(c) causes said data reader to read data identified by said choice from the storage device; and
(d) causes said item of information to be generated from said data and presented on said screen; andsaid control means including a different identifying code and a descriptor for each menu choice corresponding to an item of retrievable information; and said directory means comprising a single dedicated control element which can be employed by a system user during or following the presentation of said first item of information to reset said control means for the acceptance of the identifier code corresponding to the second item of information. - View Dependent Claims (21)
