                 HoloFlex: he will be the future of the smartphone and flexible holographic?

                          

Developed by Canadian researchers, HoloFlex is an Android smartphone which the interface responds to bending of the screen and can, as a bonus, view 3D images. The technical demonstration is impressive, but what may be its practical utility?

Just a few months ago, a team from the Human Media Lab at Queen's University (Canada) had a surprise with its concept of flexible screen smartphone dubbed ReFlex. Equipped with a bending sensor, the device can partially control the interface by folding the screen, for example to turn the pages of an eBook or play some games.

Canadian researchers went even further by integrating a display in 3D. HoloFlex is the name of this new prototype, would be the first "holographic flexible smartphone." According to its designers, it is capable of reproducing 3D images with parallax and stereoscopic multiple users simultaneously. The advantage is that there is no need for special glasses or device to keep the audience's gaze.

The touch screen is used to operate the interface in 2D (x and y axes) while flexing movement to move objects on a third axis in depth. In a demonstration video posted on YouTube, you can see how the system can manipulate 3D objects or play Angry Birds, folding screen to stretch the elastic of the catapult. When the bird is projected, the holographic effect is literally emerge from the screen.

                                  

More over, thanks to a front camera capable of measuring the depth of field, this HoloFlex also allows for holographic video calls. The fact of folding the screen brings out the 3D face of the speaker, which can look from different angles.

Technically, the device uses a flexible OLED touchscreen or FOLED a definition of 1,920 x 1,080 pixels on which is printed a plated coating 3D traveled a network of 16,640 microlenses. Each lens projects blocks of 12 pixels, circular; each of which captures the entire scene in 3D, from a slightly different perspective. This is what allows to observe objects from any angle by moving the screen.

                             

                             

Beyond the undeniable technical performance, the question arises practical applications that can offer this technology. Besides games and holographic video calls, Queen's University team suggests manipulating objects in 3D, facilitated by the flexible screen and the ability to observe from different angles. This, they say, could be useful in particular for manufacturing through 3D printing.

However, as can be seen in the images, the definition of only 160 x 104 pixels is pretty poor and fluidity of the display is far from that of current smartphones. Defects that will probably be corrected as the material 3D printing techniques and electronic components progresses.
