Abstract
One embodiment in accordance with the invention includes a two-dimensional capacitive sensor apparatus. The two-dimensional capacitive sensor can include a first sensing element having varying width, a second sensing element having varying width, and a third sensing element having varying width. Additionally, the first sensing element, second sensing element, and third sensing element are substantially parallel to a first axis. Furthermore, each of the first sensing element, second sensing element, and third sensing element can be located such that they are not required to overlap each other to determine a first location along the first axis of a two-dimensional space. Moreover, the first sensing element, second sensing element, and third sensing element can have a cumulative width that is substantially constant.
