Reducing corner tap zones

[twowheels]

After multiple failed attempts to look up words near the corner of the screen I want to reduce the size of the corner gesture tap zones, and would like to confirm my understanding prior to messing with the advanced options.

It seems that the DTAP_ZONE_[TOP/BOTTOM]_[LEFT/RIGHT] structures are the ones that I want to edit, and it also seems that the x,y,w,h variables are what I want to change, with the values being a fractional ratio of the width, so to make them half the size I’d change 1/8 to 1/16, or more specifically:

DTAP_ZONE_BOTTOM_RIGHT = { x = 7/8, y = 7/8, w = 1/8, h = 1/8}

…becomes…

DTAP_ZONE_BOTTOM_RIGHT = { x = 15/16, y = 15/16, w = 1/16, h = 1/16}

…and, looking at how they’re used, it looks like I could also use floating point percentages, such as:

DTAP_ZONE_BOTTOM_RIGHT = { x = 0.9, y = 0.9, w = 0.1, h = 0.1}

Am I reading the code correctly?

I think this is correct.

If you leave this as it is, you will also have a dead zone between 7/8 and 15/16 in each direction. Don’t know if you are OK with that. If not, you should also “stretch” the bottom/top tap zones.

In KOReader’s User Guide, page seven you can find a tapzone map. Might get handy at times like this: http://koreader.rocks/koreader-user-guide.pdf

I’m not following what you meant by this? What dead zone?

I did mean to edit all four corners, just used the one more complex corner for my example.

Did you mean if I only edit h and w, but not x and y? To leave a safe buffer?

[mergen3107]

No, I mean if you only shrink corners and do not resize bottom/top tap zone parameters, then there will be zones around corners that are not assigned to neither corners nor bottom/top tap zones. Check if you are OK with that (for text selection that might be good actually, but I haven’t tested such config yet)

Ah, OK -- I get it now. I think I'd be OK with that. I think I'll experiment a bit on a Linux build where it's easier and faster to restart over and over before committing to doing it on my Kobo.

What I usually do about the problem of corner selections is to assign a gesture to toggle the corner shortcuts on/off.

[twowheels]

That’s an interesting, and possibly easier, solution.

These are my tap zone settings to shrink the corner zones in half (or more like, a quarter of the area). Now I no longe have trouble looking up words or highlighting near corners.

* DTAP_ZONE_BOTTOM_LEFT =
* h = 0.075
* w = 0.075
* x = 0
* y = 0.925
* DTAP_ZONE_BOTTOM_RIGHT =
* h = 0.075
* w = 0.075
* x = 0.925
* y = 0.925
* DTAP_ZONE_TOP_LEFT =
* h = 0.075
* w = 0.075
* x = 0
* y = 0
* DTAP_ZONE_TOP_RIGHT =
* h = 0.075
* w = 0.075
* x = 0.925
* y = 0

Thanks. I got busy and didn’t experiment with them since I posted. I might just try your numbers.
