Designs for the Better World

Trou – Hologram Projecting Flexible Mobile Phone Concept

This is the second idea I submitted for a future mobile design competition held last month. The theme was “Design the mobile phone of 2020″.



The technology of holography is progressing day by day. In 10 years, I hope it will have already been developed for mass production and will of course used in our mobile phones. The area conventionally used for a display in a mobile phone will no longer need to be a screen with 3D projecters. Instead, it could be a hole, which allows another useful purposes.


At the same time, the materials used for the outer body of a mobile phone will become softer and softer. By successfully combine those attributes, there could be a mobile phone with a flexible vacant frame, which projects hologram in the vacant area.

When you have it in your hand, you can use it just as a conventional mobile phone except for the fact that what you see is 3D holography!

Because its frame area is flexible enough to let your wrist go through the hole, you can wear it around your wrist. A quick phone answering can be done while you are wearing it.


3D projectors are located inside the flexible frame, which project dramatic holography.

    This is a really cool concept! I like how you took flexible, bendable materials into account because a lot of research is being done in this area right now.

    Good job!
