METHOD OF APPLYING HAPTIC FUNCTION TO ELELCTRONIC FRINDLE AND ELECTRONIC FRINDLE ELECTRONIC DEVICE AND ELECTRONIC WRITING SYSTEM FOR PERFORMING THE SAME.

摘要

The present invention relates to a technology for applying a haptic function to an electronic writing instrument, wherein an electronic device displays at least one image and detects at least one of a material or a painted degree of an image displayed in response to the movement of the electronic writing instrument. Thus, haptic data may be determined based on at least one of a material or a painted degree of the detected image, and the determined haptic data may be transmitted to the electronic writing instrument, so that the electronic writing instrument may perform a haptic function based on the haptic data. Therefore, the user can take notes while feeling a sense of touch, strength, and motion similar to that of taking notes offline.
