Abstract
The method and device for converting sensing information are disclosed. Each first touch related sensing information of a first sensing information is detected. At least one of the first touch related sensing information is converted. Each converted first touch related sensing information is replaced by a corresponding second touch related sensing information, whereby the first sensing information is converted into a second sensing information.
Claims16
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.
A device for converting sensing information, comprising a controller or a host for performing at least the following operations:
- 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.
