Google has launched two experimental products will change the way users search for pictures and news

A feature known as Similar Images uses a picture rather than text to find other matching images.

Timeline presents information already available in Google News but organised and displayed chronologically.

Alongside these features is a new version of Google Labs, in which users can take a peek at what its thousands of engineers are working on.

Amid past criticism that Google has wasted too much time and effort on projects that have little impact, the aim of the Labs upgrade is to make prototypes available earlier.

“The idea we are trying to build here with Labs and the culture of innovation is to close the gap at the point of which a new idea is hatched and the time it takes to get into the hands of users for feedback,” said Google director of product management R J Pittman.
