Feedback for command buttons
(double post since the crossposter is down and I did not get any reply on my mail)
As I have a SE850i with touch sensitive buttons at the bottom of the
screen it is nice to have some feedback when the command buttons are
pressed. The phone itself indicates a touch by changing the state for
a short time (color / image overlay). This is also useful for normal
phones when the painting might be a bit slow or when an action takes a
bit to long to avoid users pressing the button multiple times...
Any ideas on how to implement this?
