The ASUS Zenfone AR is the world's thinnest smartphone that offers a 3D Time-of-Flight (ToF) camera for 3-dimensional perception of its surroundings in real-time.

AR enriches the perception of the real environment with written text as well as virtual objects that are embedded in correct scale and realistic perspective. For instance, these virtual objects may be animated animals or domino bricks in gaming applications. Projecting virtual furniture into a real home environment before ordering items at an online store is another application example. Besides consumer applications, AR can also be used in industrial manufacturing for maintenance of complex equipment and construction.

The REAL3 image sensor chip is the key component of the world's smallest 3D camera module for smartphones. It is based on the Time-of-Flight (ToF) principle and measures the time the infrared signal takes to travel from the camera to the object and back again. The elapsed time is called "time of flight". Compared to other 3D sensing principles, ToF offers advantages in performance, size and power consumption of battery-operated mobile devices.
