New submitter CanHasDIY writes "Tired of waiting for the Pip-Boy or Omni-Tool to be invented? Never fear! Nokia is developing the basic technology needed to make your dreams a reality: haptic-feedback tattoos. According to the patent application, Nokia is proposing 'a material attachable to skin, the material capable of detecting a magnetic field and transferring a perceivable stimulus to the skin, wherein the perceivable stimulus relates to the magnetic field.' Basically, the process is the same as for normal tattooing; the difference is in the ferromagnetic ink. Kind of brings new meaning to the term 'embedded device,' doesn't it?"
