Around the same time Sony was working on a PSP camera accessory and GPS receiver that plugged into the USB port Sony also planned this.
Unreleased PSP Accessory From Sony Would Have Added A Touch Screen And Cell Phone Service
Itís a diagram from a patent application filed by Sony Computer Entertainment that details a touch panel accessory. Users would plug the device in the PSPís USB slot and flip the touch screen on top of the PSP. A stylus could be used to tap an onscreen keyboard to input characters or play games that worked with the hardware.
Sony also planned to release the touch panel with a cellular radio, which would turn the PSP into a portable phone. The difference between the two devices is the portable phone accessory would have numeric keys drawn on the touch screen to make the PSP feel like a regular telephone.
Plans for both accessories along with the camera and GPS receiver were drafted in 2004, according to a Japanese patent. While the touch screen was scrapped, Sony finalized the camera (released in 2006) and GPS receiver (2007).
