You know what bothers me the most about using those touch screen devices? It's when I have to glance at the screen every time I make a move to see what's coming up next.
There is no way for me to find the necessary controls without looking, like changing tracks, making a call, adjusting the volume, etc.
But now, Nokia has come up with an interesting idea to solve this problem - swipe gestures on the touch screen for your mobile phone or music player.
The concept is actually quite simple: you make a specific gesture on the screen within a certain interface, and the software responds by making a corresponding adjustment to control some applications, such as volume, track progress, etc.
