The ASUS ZenFone AR is the world’s first commercial Tango-enabled device to be powered by the premium tier Snapdragon 821 processor.
Tango is a new technology from Google for smartphone augmented reality (AR) that aims to make smartphones smarter by giving them an understanding of the world around them. Tango is a combination of hardware (sensors/cameras) and software that is designed to let mobile devices see what we see and sense movement with greater realism.
Only Qualcomm® Snapdragon™ processors power the world’s first commercial Tango-enabled mobile devices. The Snapdragon 835, 821, 820, 653, and 652 processors all support Tango, and so will future Snapdragon 800 series and 600 series processors. Qualcomm Technologies has worked closely with the Tango team to design custom software optimizations for Tango in these premium- and high-tier Snapdragon processors.
Snapdragon 821 processor: powering the new ASUS ZenFone AR
Jan 4, 2017
Snapdragon processors are designed to support immersive, graphically rich smartphone AR experiences through cutting-edge computer vision, 3D graphics, and sensor processing technologies.
Using their built-in sensors, Tango-enabled devices are engineered to sense and capture the 3D measurements of a room, which support exciting new use cases, like real-time modeling of interior spaces and 3D visualization for shopping and interior design.
Using Tango’s motion tracking capabilities, game developers can experiment with 6DoF to create immersive 3D AR gaming experiences, transform your home into a game level, or create magic windows into virtual and augmented environments.
Tango relies on area learning to allow you to navigate precisely through a shopping mall, or even find a specific item at the store when that information is available.*
Select premium-tier and high-tier Snapdragon processors, optimized for Tango, effectively are designed to provide an all-in-one solution for Tango; there is no need for external co-processors. This is a testament to the high-performance, power-efficient, and versatile architecture of Snapdragon processors, including the Qualcomm® Hexagon™ DSP (digital signal processor) and built-in time stamping in particular.
Snapdragon processors are designed to quickly process data from five sensors simultaneously: a gyro, an accelerometer, and three camera sensors; two of the camera sensors are specific to Tango for depth and motion-tracking. These sensors combined with a built-in global clock are engineered to perform highly accurate and uniform time stamping every +/- 50 µs to deliver an optimal AR experience where 3D graphic overlays track more naturally to the physical surroundings.
With Snapdragon processors, all Tango processing is done by a single, integrated system-on-chip (SOC) that efficiently distributes the workload to the most appropriate processing component or combination of components for a given task. A Hexagon DSP is designed to handle computer vision workloads like 6 DOF positioning, which frees up the CPU and GPU to handle graphics rendering and other processes critical to an optimal smartphone AR experience.
