Abstract
A touchpad includes a first substrate and a second substrate, at least one of which is flexible. A resistor on the first substrate has a narrow shape dividing the first substrate into two regions. A set of conductors in electrical contact with the resistor extend from the resistor into the two regions. A second resistor and at least one second substrate conductor in electrical contact with the second resistor are on the second substrate. This construction allows the touchpad to have an outer shape is not restricted by the need for rectangular coordinates.
