The research team of Queen’s University’s Human Media Lab developed the worlds first flexible, bendable smartphone called Reflex. This smartphone has a new way of physical interaction which is gained by bending it in different ways. If the smartphone is bent on right side, pages can be flipped through fingers as we do with real book pages. It is equipped with a LG Flexible OLED HD touch screen display, Android 4.4 KitKat OS. Behind the display, there are bend sensors which can detect the amount of force from bending to benefit from different input interaction.
Watch this video, how interaction is done by bending using certain amount force.
