Abstract
In one embodiment, an electrical device may inject one or more first electrical signals into a resistive layer of a touch sensor. The device may receive one or more second electrical signals each corresponding to a first electrical signal injected by a first electrode. The device may determine, based on the one or more second electrical signals, a vector with each element of the vector corresponding to a value associated with a particular second electrical signal. Each element may depend at least on: a relative location between the first electrode injecting the first electrical signal and a second electrode receiving the second electrical signal, the signal frequency, and a user touch location on the touch sensor. The device may determine the user touch location based on the vector using at least one of a lookup table, a curve-fitting coefficient set, or a machine-learning model.
