Over the last few weeks, I've had the chance to test a few devices that utilize various forms of haptic feedback when you're touching the screen to input data.
- The BlackBerry Storm uses a "clickable" screen that acts like a button (SurePress technology). You have to press down on the screen like a large button to enter most of your data. This way, you're "sure" when you're entering data.
- Several Windows Mobile devices use a tiny buzz/vibration each time you tap on the screen. This is something that is controlled via software, so you can customize it quite a bit. This feature is currently available on the Samsung Omnia and also on several HTC phones (through custom ROMs and TouchResponse over at XDA developers).
