Claim One:
1. A method, comprising: detecting a presence of a conductive object in a first area of a sensing device using a first scan of the sensing device, wherein the first area is less than an entire area of the sensing device, wherein the sensing device comprises a plurality of first scan groups, wherein each of the plurality of first scan groups comprises two or more sensor elements coupled together during the first scan; and detecting the presence of the conductive object to determine a position of the conductive object within the first area using a second scan of the first area of the sensing device, wherein detecting the presence of the conductive object within the first area using the second scan comprises: selecting a second scan group that includes the first area in which the presence of the conductive object is detected during the first scan, wherein the second scan group includes two or more sensor elements that are not coupled together during the second scan; and scanning the two or more sensor elements of the selected second scan group that includes the first area during the second scan, wherein each sensor element of the two or more sensor elements is separately scanned during the second scan.
