1. A handwriting data generation apparatus comprising:
a memory containing processor-executable instructions; and
a processor coupled to the memory and configured to perform, when loaded with the processor-executable instructions:
determining target stroke data, which is at least part of stroke data generated according to handwriting input made by a pen, wherein the stroke data includes position data and a pen pressure value of the pen;
generating haptics data indicating tactile feedback to be associated with the target stroke data, wherein the haptics data is different from the pen pressure value;
associating the tactile feedback with the target stroke data; and
generating digital ink including the stroke data and the haptics data;
wherein the target stroke data included in the digital ink is reproduced to display the target stroke data on a screen, and the haptics data included in the digital ink is reproduced, when the digital ink is reproduced, to exhibit the tactile feedback in association with the displayed target stroke data.
