Peering into the future of displays: Holographic glasses, 3D screens abound at CEATEC

Konica Minolta thinks it has something unique to add to the emerging smart glasses field—holographic know-how.

The photocopier maker is showing prototypes of glasses that project holographic images at the Ceatec 2014 tech expo outside Tokyo this week.

The glasses feature what the company calls a holographic optical element (HOE), a transparent film that sits on the right lens of the glasses while a bulky, cylindrical electronics module lies on top of it.

A relatively large battery unit is connected to the prototype glasses by a wire. The device also houses Wi-Fi and Bluetooth modules for smartphone connectivity.

During a demonstration with a stand-alone HOE mounted on a rack, various full-color images could be seen through it overlaid on a background video of a busy city street.
