Having read chapter 1, you’ve got a solid understanding of the underlying physics involved in capacitive touch sensing. Now, it’s time to move towards concepts involving touch detection!
First, you’ll see a high level overview of how touches in capacitive touch sensors are translated to the ultimate goal of capacitive sensing: intuitive user experience (UX).
Then, you’ll get acquainted with the two basic capacitive sensing mechanisms: self and mutual capacitive sensing.
Finally, you’ll learn how the industry classifies touch sensor applications as one, two or three dimensional, and the detection capabilities that each category has.
