K5 Touch Prevent

[DropDeadAlex]

Hi Everyone.

I would like to know if there's a way to prevent the functions associated to touch the screen. I mean: when I am reading, is more comfortable to put my thumb in the middle of the screen to hold the my ppw1. But if I do it, the dictionary, the next page, or whatever is called.

I just wanna to hold the ppw1 with my thumb in the screen without it do something unwanted.

Someone knows something like this?

Buy a used PW1 with a broken touch screen?


Find a soft cotton glove - cut thumb off of glove, wear on the middle-of-screen thumb.
(yes, really, not a joke)
You may have to experiment with the thickness of the glove as a thumb cover.

As knc1 said.

The Kindle PW1/2 use capacitive touchscreens, you would not be the only MobileRead member to use a glove to prevent activating the touch sensor.

Thanks. Nice tip, guys


But no one thought about to put an "double click" function in the KUAL or something like this? Something like to active a function that demands you to tap a double click to press the "buttons".


Like the "prevent screen saver" in the KUAL menu. Actually the double click would be much more useful than this.

...not intending to be rude

I came up with a solution for Kindle Touch once.
Maybe someone could adjust it to work with double click on PW.

a way to implement double click could be, only register the 'even' number of touch.
so, if it's the first touch, do nothing.
if the second touch, accept it.
start the loop again.

i guess you would want to make a timeout too, so the 2nd touch has to happen within .5 seconds from the 1st.

surely there must be a way to hook in to the touch screen and do that - for the people in the know who want to do this.
good luck

i remember seeing this beore, nice idea, although i don't have a use for it personally.
it should be very possible for someone to put the ideas i wrote above, into your code, if that would be ok

-edit. i just realized, doing it so simply like i said, you could press anywhere initially, and have the 2nd press at a completely different part of the screen, and it would reigster.
it would be best to have some leeway, the 2nd click is only recognized if it is +-5px of the first.


i wrote some basic, unworking, out of context code. i started working with baf's program, although having never worked with X11, never complied anything for kindle, etc etc, i'm not in a position to test it out so it's not really worth my time to do anymore since i won't be able to see what is right and wrong.
if anyone else wants to carry on from what i did then:

Spoiler:

//////
bool IgnoreTouch = true; //will the touch be ignored or not
bool isSecondTouch = false; //is this the second touch? -- is this NOT the first touch in 0.5 seconds?

int doubleClickDuration = 500;
int previousX = 0; // xpos of first click
int previousY = 0; // ypos of first click
//////





clickTime = xev.xkey.time;
timeDiff = (long) xev.xkey.time - (long) clickTime;

//check if this could be a double click -  see if the time difference between this touch and the previous is 0.5 seconds or less
if(timeDiff <= doubleClickDuration){
	isSecondTouch = true;
} else {
	isSecondTouch = false;
}


if(isSecondTouch){
	//if 2nd touch is +- 1px away from 1st
 	if( (xev.xbutton.x >= previousX - 1)  && (xev.xbutton.x <= previousX + 1) ){

 		if( (xev.xbutton.y >= previousY - 1)  && (xev.xbutton.y <= previousY + 1) ){

 			IgnoreTouch = false;

 		}
	}
}

//if this is a first touch, save the position so that we can check against it in the second touch
//because the touches need to be in the same place
if(!isSecondTouch){
	previousX = xev.xbutton.x;
	previousY = xev.xbutton.y;
}

ow man...

What I need to do this? Are there Some Develope Kit? Some tutorial/ firsts steps in the kindle programation...
