[bbc] Virtual Reality has been a mainstay of sci-fi for decades but 2010 could see a pared-down version become mainstream.
Augmented reality (AR) has had a quiet launch on mobile handsets but it set to explode next year, experts say.
AR is a technology that allows data from the web to be overlaid on a view of the physical world.
Although a relatively small sector at the moment, analyst firm Juniper Research predicts that AR will generate incomes of $732m (£653m) by 2014.
AR allows mobile operators to combine the increasing functionality of smartphones, such as GPS, video and accelerometers, with the increasingly available number of location-based apps.
Already mobile phones use location technology to help people find their way around, such as an iPhone app developed by UK firm Acrossair to help people find their nearest tube station.
