Abstract

An electronic device includes a touch-sensitive display screen to display a graphical representation of a mathematical relationship and to enable a user to enter a one-dimensional touch gesture thereon for performing a one-dimensional adjustment function for the displayed graphical representation. A display adjustment module interprets the one-dimensional touch gesture and performs the one-dimensional adjustment function. The display adjustment module performs a one-dimensional zoom adjustment function in response to one of a one-dimensional pinch touch gesture and a one-dimensional spread touch gesture. The one-dimensional zoom adjustment function increases or reduces a displayed range of values in a first dimension while maintaining unchanged a displayed range of values in a second dimension of the displayed graphical representation.

Claims

1. An electronic device, comprising:

a touch-sensitive display screen to display a graphical representation of a mathematical relationship and to enable a user to enter a one-dimensional touch gesture thereon for performing a one-dimensional adjustment function for the displayed graphical representation; and

a display adjustment module to interpret the one-dimensional touch gesture and perform the one-dimensional adjustment function, wherein the display adjustment module performs a one-dimensional zoom adjustment function in response to one of a one-dimensional pinch touch gesture and a one-dimensional spread touch gesture, wherein the one-dimensional zoom adjustment function increases or reduces a displayed range of values in a first dimension while maintaining unchanged a displayed range of values in a second dimension of the displayed graphical representation.

2. The electronic device of claim 1, wherein the display adjustment module performs a vertical zoom-out adjustment function in response to a vertical pinch touch gesture, wherein the vertical zoom-out adjustment function increases the displayed range of values in a vertical dimension while the displayed range of values in a horizontal dimension remains unchanged.

3. The electronic device of claim 1, wherein the display adjustment module performs a vertical zoom-in adjustment function in response to a vertical spread touch gesture, wherein the vertical zoom-in adjustment function decreases the displayed range of values in a vertical dimension while the displayed range of values in a horizontal dimension remains unchanged.

4. The electronic device of claim 1, wherein the display adjustment module performs a horizontal zoom-out adjustment function in response to a horizontal pinch touch gesture, wherein the horizontal zoom-out adjustment function increases the displayed range of values in a horizontal dimension while the displayed range of values in a vertical dimension remains unchanged.

5. The electronic device of claim 1, wherein the display adjustment module performs a horizontal zoom-in adjustment function in response to a horizontal spread touch gesture, wherein the horizontal zoom-in adjustment function decreases the displayed range of values in a horizontal dimension while the displayed range of values in a vertical dimension remains unchanged.

6. The electronic device of claim 1, wherein the display adjustment module continually and dynamically adjusts the graphical representation while the touch gesture is being performed.

7. The electronic device of claim 6, wherein the display adjustment module causes the adjustment of the graphical representation to momentarily pause at a set of predetermined zoom factors.

8. The electronic device of claim 1, wherein the one-dimensional zoom adjustment function varies depending upon whether the touch gesture involves two moving digits of the user, or one moving digit and one fixed digit.

9. The electronic device of claim 8, wherein the display adjustment module performs a one-dimensional zoom about an axis of the graphical representation when the touch gesture involves two moving digits of the user, and performs a one-dimensional zoom about a point under the fixed digit when the touch gesture involves one moving digit and one fixed digit.

10. The electronic device of claim 1, wherein rotation of digits of the user performing the one-dimensional touch gesture locks a current zoom factor, and further rotation provides a fine adjustment to the zoom factor.

11. An electronic device, comprising:

a touch-sensitive display screen to display a table of values of a mathematical function and to enable a user to enter a touch gesture thereon for performing an adjustment function for the displayed table of values; and

a display adjustment module to interpret the touch gesture and perform the adjustment function, wherein the display adjustment module performs a zoom adjustment function in response to one of a pinch touch gesture and a spread touch gesture, wherein the zoom adjustment function modifies a delta value between consecutive values in a column of the table.

12. The electronic device of claim 11, wherein the table of values includes a plurality of columns, including a first column containing values for an independent variable of the mathematical function and a second column containing values for an expression defined in terms of the independent variable, wherein the values in the first column have a constant delta value, and wherein the zoom adjustment function involves multiplying the constant delta value by a scale factor.

13. The electronic device of claim 12, wherein the zoom adjustment function is performed with respect to a selected value in the first column of the table, and wherein the selected value is held fixed during the zoom adjustment function.

14. The electronic device of claim 11, wherein the touch gesture is one of a vertical pinch touch gesture and a vertical spread touch gesture, and wherein the adjustment function increases the delta value between consecutive values in a column of the table for the vertical pinch touch gesture and decreases the delta value between consecutive values in a column of the table for the vertical spread touch gesture.

15. An electronic device, comprising:

a touch-sensitive display screen to enable a user to enter a touch gesture thereon for performing an adjustment function for displayed information; and

a display adjustment module to interpret the touch gesture and perform the adjustment function, wherein the display adjustment module performs at least one of a numerical result adjustment and a symbolic expression adjustment, wherein the numerical result adjustment involves decreasing a number of digits displayed for a selected numerical result in response to a pinch touch gesture to round the selected numerical result to fewer place values, and increasing the number of digits displayed for the selected numerical result in response to a spread touch gesture, and wherein the symbolic expression adjustment involves factoring and simplifying a selected symbolic expression in response to a pinch touch gesture and expanding the selected symbolic expression in response to a spread touch gesture.
