E3: Playstation gets augmented reality Harry Potter book

Sony has unveiled Wonderbook - an augmented reality product for its Playstation 3 games console. When users hold up specially created books to a connected camera they appear on screen with added interactive graphics, which can in turn trigger mini-games. The first book will be a new Harry Potter title partly written by the series' author J.K. Rowling. The announcement was made at the E3 video games trade show in Los Angeles.

The move is part of efforts designed to keep people interested in the Playstation 3 as Sony continues to work on its successor. The firm's share price fell below 1,000 yen ($12.77, £8.29) earlier this week for the first time since 1980. Investors are worried about competition from Samsung and Apple as well as the strength of the Japanese currency. The firm will face a fresh challenge later in the year when Nintendo releases its next-generation console the Wii U.
