A method for using a slider-based capacitive sensor to implement a user interface having discrete buttons. Button locations are designated on a slider-based capacitive sensor having at least two conductive traces such that a user input at any button location results in a capacitance change in the conductive traces. Locations of inputs are distinguishable by ratios between the capacitance changes of the conductive traces, which can be correlated to a particular button location. Ratio ranges corresponding to areas covered by each button are used to identify which button has received an input.
