a neural network processor configured to receive a sensing signal from an input sensor and to output one of a first sensing result or a second sensing result using a prediction model;

a first input processor configured to receive the first sensing result and to determine whether a first input is present based on the first sensing result; and

a second input processor configured to receive the second sensing result and to calculate a coordinate signal for a second input based on the second sensing result, wherein the first input processor includes:

a proximity processor configured to determine whether the first input is present based on the first sensing result, wherein the first input depends on a proximity of an object relative to the sensor.
