1. A method for converting sensing information, comprising:

  • obtaining a first sensing information;

    detecting each first touch related sensing information of the first sensing information, wherein the first touch related sensing information is partial first sensing information corresponding to touch or proximity of an external object; and

    generating a second sensing information based on the first sensing information, the second sensing information being generated by replacing only a part of the first sensing information with a second touch related sensing information, wherein the second sensing information comprises the second touch related sensing information and the first sensing information without replacement, and the part of the first sensing information comprises at least one of first touch related sensing information of the first sensing information, wherein each value of each first touch related sensing information is one of a dual difference and a difference, and each value of each second touch related sensing information is the other of the dual difference and the difference.
