Soon you maybe able to use different fingers to control your iPod to play, fast-forward, rewind, or pause… Apple had filed with the US Patent and Trademark Office it new technology invention titled “Control of electronic device by using a person’s fingerprints”. The new design describes a new user interface controlled by fingerprints.

The new technology invention embeds a fingerprint reader to a gadget such as iPod. By placing your index finger on the reader, you may be able to fast-forward the content. By placing your middle finger on the reader, you may be able to pause the device. The reader would also take into consideration of how long the finger is placed on the device, therefore triggering another behavior.

This seems to be similar to the touch pad controls Apple currently has in its MacBooks. But, it’s still unclear on what specific use Apple has planned. However, this new technology invention would allow Apple to keep the size of its iPods small. A fingerprint sensor could potentially replace all buttons and dials that’s currently employed in the iPods. Then again, the design may simply be a biometric locking mechanism built into future Apple devices.
