A high-performance accelerometer and gyroscope were added after testing several competing models in the MARS lab at the University of Minnesota.Several hundred Peanut devices were distributed to early-access partners including university researchers in computer vision and robotics, as well as application developers and technology startups.Lenovo's Phab 2 Pro is the first commercial smartphone with the Tango Technology, the device was announced at the beginning of the year 2016 and launched in as of august 2016.
Some of the Tango apps are Measure It (for measuring objects), Solar Simulator, Wayfair (for testing furniture arrangements in rooms), and Cydalion (navigation app for people with visual impairments), among many others.
Tango (formerly named Project Tango, while in-testing) is an augmented reality computing platform, developed and authored by Google.
It uses computer vision to enable mobile devices, such as smartphones and tablets, to detect their position relative to the world around them without using GPS or other external signals.
It features a 2.3 GHz quad-core Nvidia Tegra K1 processor, 128GB flash memory, 1920x1200-pixel touchscreen, 4MP color camera, fisheye-lens (motion-tracking) camera, an IR projector with RGB-IR camera for integrated depth sensing, and 4G LTE connectivity. "Peanut" was the first production Tango device, released in the first quarter of 2014.
It was a small Android phone with a Qualcomm MSM8974 quad-core processor and additional special hardware including a fisheye motion camera, "RGB-IR" camera for color image and infrared depth detection, and Movidius Vision processing units.
At CES, in January 2016, Google announced a partnership with Lenovo to release a consumer smartphone during the summer of 2016 to feature Tango technology marketed at consumers, noting a less than $500 price-point and a small form factor below 6.5 inches.
