Potential features of a future touchscreen iPod nano were revealed this week in a new patent application published by the U.S. Patent and Trademark Office entitled "Environment Sensitive Display Tags." The document, discovered by AppleInsider, describes adding new sensors to the iPod nano, including a camera, to add new functionality.
The application concentrates on software features like screen savers, allowing information or content to be displayed on the device. Apple's proposed invention would use sensors that would display unique content, or change the manner in which it is displayed.
But even more interesting are the illustrations shown in the application that include references to a camera and games. Currently, the sixth-generation iPod nano does not feature a camera, and cannot run software outside of what is preinstalled on the device.
In addition to a camera, the application also makes mention of the inclusion of a motion sensor, temperature gauge, and a microphone. Each of these sensors could be used to dynamically alter the way a screensaver would be played on an iPod nano.
While the application itself makes no mention of the iPod nano model in its text, the images show a small device with no physical buttons with an appearance similar to the multi-touch model Apple released last September.
The mention of a camera in the patent filing comes just days after a new photo claimed to show a seventh-generation iPod nano with a rear-facing camera, and without the built-in clip featured on the sixth-generation model. Another picture, also suggesting Apple could add a camera to its tiny media player surfaced in early April.
A camera was previously featured on the iPod nano in its larger fifth-generation model, released in 2009 and featuring the classic-style click wheel for input. Previous version of the device also supported iPod Click Wheel Games, but no games are available for the touchscreen sixth-generation iPod nano.
While the iPod nano operating system is designed to look and feel like iOS, which powers the iPod touch and iPhone, it is actually a different, unique operating system. In December, hackers managed to crack the software, but have not yet released any useful hacks aside from removing icons.
Apple's patent application was first filed in November of 2009. It is credited to Duncan Kerr, Nicholas King, and Michael B. Victor.
