Holoflex: holographic, flexible smartphone

06.05.2016 | Human Media Lab | www.hml.queensu.ca

Researchers at the Human Media Lab at Queen’s University have developed the world’s first holographic flexible smartphone. The device, dubbed HoloFlex, is capable of rendering 3D images with motion parallax and stereoscopy to multiple simultaneous users without head tracking or glasses.

HoloFlex features a 1920x1080 full high-definition Flexible Organic Light Emitting Diode (FOLED) touchscreen display. Images are rendered into 12-pixel wide circular blocks rendering the full view of the 3D object from a particular viewpoint. These pixel blocks project through a 3D printed flexible microlens array consisting of over 16,000 fisheye lenses. The resulting 160 x 104 resolution image allows users to inspect a 3D object from any angle simply by rotating the phone.

First holographic smartphone

HoloFlex is also equipped with a bend sensor, which allows for the user to bend the phone as a means of moving objects along the z-axis of the display. HoloFlex is powered by a 1.5 GHz Qualcomm Snapdragon 810 processor and 2 GB of memory. The board runs Android 5.1 and includes an Adreno 430 GPU supporting OpenGL 3.1.

Queen’s researchers will unveil HoloFlex in San Jose, California at the top conference in Human-Computer Interaction, ACM CHI 2016, on Monday May 9th.
