Just for the record. In our company we manufacture control systems for <br>
automatic machines, and we provide a touch-screen industrial computer, <br>
for easy operator interaction.<br>
<br>
In the operating instructions we write:<br>
<br>
"If you have difficulties with touch screen, please touch anywhere on <br>
the screen and watch the cursor position, If it happens not to be <br>
exactly at the location you touched, please perform the touch screen <br>
calibration procedure explained below"<br>
<br>
Of course we're not using Windows, but rather Linux for a lot of <br>
reasons, the main one being that we need real-time responsiveness. <br>
However this one adds one more reason to the list.<br>
<br>
To be honest I must admit that industrial grade touch screens have <br>
dramatically improved during the years, and nowadays the recalibration <br>
is seldom required, nonetheless...<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I take it those are resistive touch screens? For those calibration is sometimes necessary (especially older ones as you said). For capacitive touch panels (be it smartphone or tablet) I haven't found the need for that. </div><div dir="auto"><br></div><div dir="auto">Regards, </div><div dir="auto">Sven </div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
