Hi Jerry, See my comments below: 1. For single finger, should they add the algorithm? 2. For two finger, should they add the algorithm? Comment: Basically, TSC2013-Q1 is not able to provide you with direct 2-finger coordinates. Some algorithms are required to detect 2-finger gestures, such as 2-finger zoom in/out and 2-finger rotate. As for single touch, you can get very precise x&y coordinates directly from TSC2013-Q1 . If you want 1-finger scroll or flick, extra algorithms are needed as well. 3. Any recommend resistor vrange for the panel? Comment : No, there are no requirements on the sheet resistance. However, we do recommend 4-wire resistive touch screens with low activation force (from center area down to 0.1 to 0.3 N) to enable smooth dual-touch operation.
