To make augmented reality work and be convincing and reliable, the generation of the augmented image and the registration of the real and virtual image has to be very fast and accurate. If it isn't fast enough, it wouldn't provide the user with a real-time like perception and smooth continuity of the virtual objects that respond to the real physical objects in the scene and it would render with visible jumps. We also need to consider the movement and pose of the camera because those changes in value measurement can lead to generating a wrong placement of the virtual image or make it appear like it is not stationary. Furthermore, if there is a significant delay in the camera position calculation or improper alignment of the virtual objects, the virtual image would look like it is lagging behind any motion happening in the real scene.
The Asus ZenFone AR time samples all of the sensor data within plus or minus 50 µs precision according to the press release, providing very fast sensor processing. This allow user to get a reliable and concurrent representation of the overlayed 3D graphics in the exact place where it should be rendered and this fast graphics overlay capability is also essential for games, where for example, you want to be able to hit a virtual game target at a specific location isn't accurate relative to the real physical world as shown in the projected video stream on the phone's screen.
Thanks to the high-frequency clock of the Qualcomm Hexagon 680 DSP, Qualcomm Spectra ISP, and the All-Ways Aware sensor core, the Asus ZenFone AR is capable of delivering the acceleration and computing power needed to support the Tango computer vision use cases. The results is a very convincing augmented reality (AR) experience for a wide range of applications, including high-quality augmented reality games, which I'm sure many of you want to experience. The Qualcomm Adreno 530 GPU can provide developers with enough power to produce high-quality 3D objects that can lead to really immersive AR games and apps.
AR feature will obviously be improved each year, but no doubt that the Asus ZenFone AR is by far the best Tango-enabled device on the market and if you have been waiting for such device and skipped the Lenovo Phab2 Pro, this is the time to pick up this phone and enjoy a very high-quality AR experience. We can just hope that more and more developers will release great apps and games to support Tango in 2017. The technology isn't great is it doesn't ignite the imagination and ambition of developers to create great content for it. I personally have no doubt that once the ZenFone AR is released, we are going to see a lot more apps for Google Tango, and maybe some of them will be announced with or slightly after the official Asus ZenFone AR announcement in CES 2017.
