Simply by winking you could start your iPod music or by raising an eyebrow you could go to the next song. These are all a reality now thanks to a new Japanese based gadget called the Mimi Switch or Ear Switch. The Mini Switch allows you to control your iPod or other devices simply by using facial expressions such as blinking an eye, smiling or raising an eyebrow. All of this is done by using tiny infrared sensors located in the headphones of the device. When the sensor detects these micro moments within the ear canal, it perform the action via the cable connecting to your iPod or device.
