Smartphone with spatial awareness – Getting started with the first Tango phone




We are constantly aware of our surroundings. Once we enter a room, we take them into us. We know where the door is, where the windows are and we are aware that we are sitting on a chair at a desk with a screen for us. Smartphones have no idea of ​​all that. They know where they are, at most, if they manage to get a good GPS fix.

Google worked under the name Project Tango for several years on a technology that smartphones just as aware of their surroundings when people have to make. It works with cameras and sensors that are able to follow movements and to measure distances. With those characteristics, the environment and objects can be mapped, and can exactly determine the device position at which it is located.

Tango technique is especially useful for augmented reality, but also in virtual reality and makes accurate navigation inside buildings as possible. With the depth camera, it is also possible to create a 3D model of entire objects or environments. Google has the technology has long been in development, but it takes two to tango and at CES was announced early this year that Google has found a partner in Lenovo. The company promised in the summer to release the first smartphone with Tango hardware. That promise is now fulfilled with the announcement of Lenovo Phab 2 Pro.

Simultaneously with the introduction of the first Tango smartphone, Google has the technology given an official name and a logo. Many changes are not what Project Tango was first, now called simply Tango .

Not only does the 6.4 “screen of the Phab Pro 2 is large, the metal body is a bit larger than what would be required for this screen size: the smartphone is almost 18cm long, together with the Phab 2 Pro Lenovo has. two phablets announced . This Phab 2 and Phab 2 Plus also has a 6.4 “screen, but are slightly smaller than the Phab 2 Pro. Incidentally, the other two Phab Tango’s no hardware on board. Thus, it can be seen that there are larger dimensions are needed to provide the required camera and hardware for eliminating Tango.

Lenovo defends the choice for large format to be that people barely call their smartphone and device use more common use where a large screen is just nice. While it is absolutely true, we still fear that the dimensions of the Phab 2 Pro for many potential buyers will be a deal breaker.

This is also used in Tango-applications, to display the image on the screen. Under the camera down the depth sensor, motion sensor and a infraroodled. The depth sensor operates to send out in combination with the latter, by a light signal, and to absorb again, the sensor can measure the distance to objects.

The large round camera above the fingerprint scanner is a wide-angle camera that can capture the entire area and also can keep moving subjects or in the holes. At the front of the unit is a regular 8-megapixel camera with an aperture of f / 2.2.

To eliminate Tango cameras, Lenovo had to make a hole in the PCB of the smartphone. The motherboard is the true to Tango module built around.
