Will the future be augmented reality glasses?
The Osterhout Design Group (ODG) has shown off a pair of augmented reality glasses costing more than £1,800.
The glasses contain lenses that project images or graphics in front of the wearer's vision.
BBC Click's Marc Cieslak tried out the glasses at this year CES show in Las Vegas.
