Are you still a Doubting Thomas when it comes to Apple's intentions of eventually introducing a stylus to the iPhone or future tablets? Well, perhaps you should rethink that position. It appears by this current patent that surfaced yesterday, that Apple is seriously thinking of reinventing the stylus by introducing us to an advanced Light Pen or even a Laser Light, states the patent. Just a few weeks back there was another very sophisticated touch screen patent that touched on future touchscreens for the iPhone and future MacBook Tablet. Today's patent is equally sophisticated. This patent introduces us to a futuristic light pen that has a cylindrical tubular tip that is both extendable and retractable when pressed against the touch display. It also discusses a light emitting diode that provides a beam of light that is channeled through an optical path. This capability, states the patent, is particular useful for pressure sensitive applications, such as Photoshop by Adobe. As noted in the illustration, the light pen appears to be tethered to the device in some way. The patent doesn't explain if the wire from the pen is retractable in some way or if it's simply a plug-in accessory. Time will tell. This patent report focuses on references to the light pen and not on the touch screen technology itself.
