By Paul Sandle LONDON (Reuters) – Mike Lynch, who sold software firm Autonomy to Hewlett-Packard for $11 billion (6.73 billion pounds), is backing a start-up focused on augmented reality – the ability to overlay information on a real-world background which some see as the next big digital craze. The technology aims to help a device such as a mobile phone to recognise objects in the real world, such as a building, and overlay relevant information onto the image on its screen. The undisclosed investment is the second by Invoke Capital, a $1 billion fund set up by the British entrepreneur after he left Autonomy last year just seven months following the HP takeover that netted him about $760 million.
