Abstract
A user's comprehension of computer-generated data is enhanced by providing a visual representation of the data including a multi-character string. Before allowing the user to initiate a desired computer operation, the user is required to correctly enter characters matching the characters of the represented multi-character string. In one embodiment, the string representation is altered as matching characters are entered and recognized. In another embodiment, the multi-character string is presented initially and then masked before the user begins to enter characters. A character mask is removed each time a correct matching character is entered.
Claims7
A system for enhancing a computer user's awareness of computer-generated data comprising:
- an output device for providing a multi-character string to be matched by a user, said output device comprising a computer display on which a visual representation of the multi-character string appears;
- an input device for enabling the user to enter individual characters, including characters in the phrase provided by the output device;
- display-controlling logic for altering the visual representation of the multi-character string as matching characters are being entered using the input device;
- and
- logic for providing an enabling signal only if the characters entered by the user using the input device match the characters of the multi-character string provided by the output device.
A method for enhancing a computer user's perception of computer-generated data comprising the steps of:
- providing a visible representation of the data using a computer display, said representation including a multi-character string to be matched by the computer user;
- receiving character-by-character inputs from the computer user;
- and
- modifying the visual representation in response to the input of each character in the input from the computer user that matches a character in the corresponding position of the data;
- and
- generating an enabling signal only if the character-by-character inputs provided by the computer user match the multi-character string included in the data representation.
A program product comprising a computer-readable medium having a computer-readable program embodied in said medium wherein the computer readable program when executed in a computer causes the computer to:
- provide a visual representation of predetermined data on a computer display, said representation including a multi-character string to be matched by the computer user;
- receive character-by-character inputs from the computer user;
- modify the visual representation in response to the input of each character in the input from the computer user that matches a character in the corresponding position of the data;
- and
- generate an enabling signal only if the character-by-character inputs provided by the computer user match the multi-character string included in the data representation.
