  • Method and apparatus for calculation with display data
    Patent number: 5390296
    Abstract: A method and apparatus for facilitating analysis of data in a data base. The data base data is displayed on a touch sensitive screen. A calculator icon is overlayed on the data. A user selects a function, such as "TOTAL," by touching a corresponding function button displayed as part of the calculator icon. The user then selects the data to be totaled by touching a row header or column header for the data rows or columns he wishes to include in the calculation. Once the data for the calculation is selected, a "=" icon is touched, and a new row or column holding the results of the calculation is inserted into the displayed data. The calculation is displayed in a window of the calculator icon as the calculation is built by the user.
