Description
From the listing uploaded by “appupdater”.
If you have a broken, damaged or defective display where appear all kinds of accidental, random, arbitrary, self, ghost ... but all the same unwanted touch.
Then this program can help you block the touch in those parts of the screen where they appear.
By blocking the touch, it means intercepting all kinds of touches and gestures in the specified zone.
There are two types of adding areas with locking of touch -
and
modes.
After the automatic screen analysis running, all touches are intercepted for the established time interval to identify the lock zones.
When analysis ended, the intercepted clicks are analyzed, minimized and combined into zones with blocked touches.
In manual mode, you need to add the necessary lock area yourself. Choose
and place the area of the desired size on to the screen.
It is also possible in the touch detector to track those parts of the screen where spontaneous touches occur.
At the top of the screen, there are first two state switches for the two types of blocking. Enable both if you use zones added by automatic and manual mode.
In the area manager you can: select active / inactive areas, change the color, size and position of the area, delete the unnecessary ones.
