Sony bolsters Vita's functions with PS3

Sony Corp. is trying to breathe new life into its PS Vita handheld.

It unveiled plans to bolster the Vita's use with PlayStation 3 consoles by making use of its front and back touch screens and giving different players different perspectives in the same game.

The use of a second screen with a controller mimics plans by Nintendo Co. Ltd. to sell a tablet-like touchscreen controller with its Wii U.

It also resembles Microsoft Corp.'s SmartGlass feature, unveiled earlier Monday, which makes use of smartphones to control video content.
