A method for providing high-resolution touch sensing on 3D object

A computer-implemented method is disclosed for designing a touch sensing arrangement for a 3D ob-ject (B), the method includes (i) performing a quad meshing of the surface of the body, the quad mesh including a plurality of quadrangular areas (Q) having side dimensions matching the mutual spacing between pairs of adjacent transmit electrode lines (T) and between pairs of adjacent receive electrode lines (R) of the touch sensing arrangement, (ii) computing a quad patch layout comprising a plurality of quad patches (P), each including a plurality of adjacent quadrangular areas (Q) of the quad mesh, selectively grouping the quad patches (P) into a plurality of clusters (C) of adjacent patches (P) and packing the clusters (C) into a plurality of cluster sets, each cluster set being associated with a respective touch controller (TC), wherein the transmit electrode lines (T) and the receive electrode lines (R) of the touch sensing arrangement are designed according to a dual edge graph of the quad mesh, and interconnecting conducting paths are established between transmit and receive elec-trode lines (T, R) of each cluster set and the respective touch controller (TC) through the internal volume of the object (B).
