In the Switch 5 there is a 1.5 to 2 second delay after any pen input before touchscreen input is enabled. Also, touch input is completely disabled while the pen is being used. This is obviously an attempt at palm rejection, however it is not, it is simply disabling the touch input when the pen is being used. This is just a lazy attempt at palm rejection.
As a digital artist, and someone who takens notes on the tablet I was keen to use the ACER Switch 5 as a design tablet. Because of this delay it is frustratingly slow to navigate without having to endlessly wait for the touch input to be enabled! I won't be reccomending ACERs to anyone who needs a touch screen for drawing to writing.
This issue is not isolated to my device, nor is it isolated to the Switch 5. Here is a link
to another page on these forums asking the same question of the Spin 5. And here is a link
to a page of the HP forums where someone was having the EXACT same issue with the HP Spectre X360. Both pages have videos to demonstrate the issue and BOTH have the same delay in touch input. In the Case of the Spectre X360, HP released a firmware to shorten the time the touch is disabled. This goes half way to solve the problem as touch input is still disabled when the pen is being used (see the second link).
I have taken the following steps to fix the issue:
Disabled the "Ignore touch input when I'm using my pen" option in the settings menu
Therefore my idea to ACER is the following
- Disable the delay between pen input and touch input.
- Enable the simultaneous use of touch and pen inputs (like any competent manufacturer should, see Microsoft)
- Implement the proper palm rejection that is used by microsoft (As seen here
- Make a program that allows us to switch between these different modes of palm rejection.
