1. A touch sensing device, comprising:
a mutual capacitive sensing controller having a plurality of distinct drive lines and a plurality of distinct sense lines, a source for driving a current or voltage separately though each drive line, a mutual capacitance sensing circuit that monitors the capacitance at the sensing lines; a plurality of independent and spatially distinct mutual capacitive sensing nodes set up in a non two dimensional array, each node including a drive electrode that is spatially separated from a sense electrode, the drive electrode and the sense electrode being configured to capacitively couple a drive line and a sense line, the plurality of drive lines configured to carry current from the controller to the nodes, the plurality of sense lines configured to carry current from the plurality of nodes to the controller, wherein the nodes comprise multiple node groups, at least a first of the node groups comprising multiple nodes, each node in a node group being associated with a sense line that is common to all nodes in the group and a drive line that is not common to any other node in the group, one node in each node group being associated with a drive line that is common to all node groups. |
