 Touch screen question
It's been a few years since I have used touch screens or trackpads, but I know it used to be that they wouldn't work properly if your hands were not scrupulously clean and dry. If there was the slightest hint of grease or moisture on your hands, they would either fail to work, or malfunction in odd ways with each drop of moisture and greasy fingerprint registering as a continuous 'contact point' on the pad/screen. Does anybody know if the latest generation touch screens still have this problem? I'm just curious to know if this will be a headache for users of Apple's iPhone, which doesn't have a keypad, but instead has everything driven by a touch-screen. I can see some kid trying to use his phone after eating fried chicken or hot wings, or a mechanic trying to make a call while covered in engine grease. If Apple is on the ball, this should not be an issue with the iPhone, but if they aren't this could be a serious embarrassment. |
