A touch input device includes a planar location sensing board, a depth sensing layer, a first interpretation unit, a second interpretation unit, and a processing unit. The planar location sensing board senses a first electrical variation of different locations in the directions parallel to the planar location sensing board due to an object approaching or touching the planar location sensing board. The depth sensing layer is disposed below the planar location sensing board and separated by a distance from the planar location sensing board. The depth sensing layer senses a second electrical variation corresponding to a degree in which the object presses the planar location sensing board. The first interpretation unit is electrically connected to the planar location sensing board. The second interpretation unit is electrically connected to the depth sensing layer. The processing unit determines a three-dimensional touch location of the object. A touch sensing method is also provided.
