Did we say tactile feedback for supposed future Windows mobile yesterday? Yes we did, and the same could now be applicable to the next generation iPhones. It is not confirmed as yet but, at lest, the Apple patent application which has three very interesting clauses waiting to be approved, does give us a lot of hope. The first clause wants tactile feedback to be a part of the touchscreen offered on the iPhone. This will help do away with the limitations of the current touchscreen format employed by Apple and the company does acknowledge those limitations-probably why tactile feedback or haptic response was thought of. A special grid of piezoelectronic actuators will be combined to fully form a tactile touchscreen. Different combinations of these actuators (upon vibration) will be used to facilitate different frequencies providing a variety of responses.
Apple is also keen on employing fingerprint recognition as an input method. The integration of this technology can facilitate usage without actually looking at the phone. The technology would help identify fingerprints for different fingers and a corresponding response will be ensued for each of the fingers. The third patent clause is that of RFID tag reader and since I cannot precisely comprehend the reason behind it, it is better not to discuss it here.
