Considering that the hype levels over the PlayStation 3 and Wii next-generation consoles, from Sony Computer Entertainment Inc. (SCEI) and Nintendo Co. Ltd. respectively, have already been cranked up to 11 it’s something of a relief to see that there’s still room for the less-pervasive handheld games consoles.

SCEI’s PlayStation Portable (PSP) in particular has had its share of bad press recently when the company projected lower sales this year, the PSP's second full year on the market. One thing that may help arrest that decline, however, is the belated arrival of two peripherals for the PSP that have been long-awaited by many handheld owners.

Both were on show Friday as the Tokyo Game Show opened in Chiba, east of Tokyo.

The first, a ¥5,000 ($43) digital camera add-on called “Chotto Shotto” (Quick Snap), is due to go on sale on November 2 in Japan. The 1.31-megapixel swiveling camera is housed in a shiny chrome case that attaches to the mini USB slot at the top of the PSP. While no games exist that make use of the camera yet, the supplied software allows users to take shots of themselves or others and add simple graphics.

The second accessory is a ¥6,000 GPS receiver that works in conjunction with four software titles initially -- a golf-course guide and shot advisor, a car-navigation package, a star-gazing application and a new version of Metal Gear Solid. The GPS unit also connects via the PSP’s USB port and will go on sale in Japan on December 7. Overseas prices and availability have yet to be announced.
