What is Project Tango? Google's AR tech explained


Project Tango

Google's Project Tango could turn out to be the biggest thing to happen to smartphone technology in years. Here's why.

When you think of Google and smartphones, you think of Android, right? But Google has its fingers in a number of smartphone technology pies, and one of the most exciting of those is Project Tango. It could transform the way you see the world – or at least, the way your smartphone sees it.

So what exactly is Project Tango all about? Let's take a look at how Google's augmented reality ambitions could revolutionise smartphones.

Announced early in 2014 and developed by Google's Advanced Technology and Projects (ATAP) team, Project Tango is Google's attempt to get mobile phones and tablets to see the way we see.

This means granting the device full spatial awareness, or the ability to understand your environment and your relation to it.

The essential aim is to get your smartphone to understand the world around it, enabling it to provide augmented reality experiences.

More recently, the likes of Intel and Qualcomm have announced reference Project Tango devices for developers to work on, which has prompted a great deal of excitement among the development community.


A Project Tango device 'sees' the environment around it through a combination of three core functions.

First up is motion tracking, which allows the device to understand its position and orientation using a range of sensors (including accelerometer and gyroscope).

Then there's depth perception, which examines the shape of the world around you. Intel provides a vital cog in this respect with its RealSense 3D camera. With this component on board, a device can gain accurate gesture control and snappy 3D object rendering among other things.

Finally, Project Tango incorporates area learning, which means that it maps out and remembers the area around it.


Well there's a bunch of obvious, but useful, stuff that Tango is capable of. And then there's the range of potential applications that people and businesses are just starting to think of.

For example you can use a Project Tango device to instantly measure a room and record an area's dimensions. This would mean that you don't have to stand around Ikea with a paper measuring tape scratching your head with an undersized pencil while you try and figure out if that sofa bed will fit in your spare room. You'll instantly have the information there on your phone.

A phone or tablet packing Project Tango and a RealSense camera makes such everyday tasks a lot simpler.

There's also potential for helping those whose eyesight may be fading. Tango recognises where a device is in relation to the environment so it can send signals by sound, or even voice, to the user. Researchers at the University of Lincoln are working on just that.

To give an idea of the potential accuracy and sophistication we're talking about here, Intel has plugged its RealSense camera (which is utilised in Project Tango devices) into drones so they can automatically avoid obstacles – even moving ones – without the need of Wi-Fi or Bluetooth connectivity.


One of the more fun applications comes in the way of gaming. More specifically, how Project Tango can use augmented reality apps to let you play games in real-world environments.

Late last year we tried out a basic robot first-person blaster using a prototype Project Tango device. Moving around a phone mounted on a Nerf gun gave us a 360-degree view of our surroundings.

This wasn't so different from using any accelerometer-packing smartphone with a VR app, but such apps don't respond to your physical movements the way they do with Project Tango. Step forward with the aforementioned app, and objects on screen start to get nearer accordingly.

Imagine sneaking your way up to a shiny little critter with perfect accuracy in Pokemon Go before throwing your Poke ball. This element alone can bring a whole new set of mechanics to mobile games.

Then there are the game environments themselves. Maps can be created using the layout of your house or garden, making level-design far more personal and familiar.

In many ways the effect of the position tracking technology is similar to using the HTC Vive VR headset except Tango doesn't require chunky lasers to understand the space around you, and it's not restrained to a specific 20'x20' area.

In many ways, then, it's closer to Microsoft's HoloLens in its focus on enhancing reality rather than creating a whole new virtual one.


It's not all fun and games. Early reports suggest that Project Tango could have some genuinely useful business applications to it.

Whether it's to map a house for an estate agent to put online or helping robots better interact with an environment, there are countless applications that can help companies do things quicker and smarter.

Collaborations with retailers like Walgreens and Target have already started in the US. Aimed at helping you part with your cash more efficiently, they're still in their infancy but give a glimpse into the shop of the future.

We've seen Project Tango likened to Google's outdoors mapping technique for its Google Maps project, but scaled down and focused on indoors environments.

That should tell you another of Google's grand plans here – to patch together the data from all Project Tango devices and map public indoor spaces, such as airports and shopping malls.

Among other things, it could open up a whole new level of location-based advertising when you walk past certain shops, or even certain aisles in the supermarket.


Of course, Google has a lot of pet projects on the go, relatively few of which actually turn in to full-blown projects. That's just the way it works.

However, Google seems to mean business with Project Tango. According to a recent Bloomberg report, the company plans to make its technology ubiquitous.

It's also said to be working on a way to easily share the 3D data that a Project Tango device gathers. In this way, other developers could benefit from the data captured by others – using another user's 3D map of a museum, for example, to build a guide app.

When will it arrive?

Google has partnered with Lenovo to make the world's first Project Tango-powered smartphone, due to launch globally in summer 2016. The handset will reportedly cost less than $500, with the two companies saying it will be less than 6.5-inches in size.

Details about what you'll be able to do with the phone are scarce at the time of writing, but the Lenovo Project Tango page names a few Tango-compatible apps which could see their way onto the forthcoming handset. Among them are Car Visualiser, which lets you take a virtual tour of a car by moving the device, MeasureIt which lets you measure objects just by pointing the phone at them, and 3D puzzle game WeR Cubed.


There's no official indication of how much Project Tango devices will cost, but really, you only need to look at the current smartphone landscape for a guide.

We can't imagine the Project Tango phone costing significantly more than a flagship Android phone or tablet – not if Google intends for it to become ubiquitous. So, anything in the £250 to £500 range, then? Sounds about right to us.

Project Tango at Google I/O 2016

There were a number of Project Tango events at Google's annual developer conference, including 'Introducing Project Tango Area learning', 'What's new with Project Tango', and a Project Tango developer panel. There was also a session on 'Gaming in Android with Project Tango'.

But perhaps most exciting was when Google's Johnny Lee (via VentureBeat) showed a video demonstrating various research projects that were underway. This included ultra-precise indoor navigation in use, complete with a waypoint overlay on the phone's display, which looks a bit like a modern first person shooter game, except those little digital breadcrumbs lead to a delicious meal or an important appointment rather than a virtual bloodbath.

Also shown off was the potential to map large buildings in 3D from the outside, while another demo showed how Project Tango could detect and remove moving objects from a captured 3D image. Google even showed off how Project Tango could help space robotics, enabling operators to accurately track the position and movements of their robots from thousands of miles away.

Market share abuse of Google, Apple and Microsoft. Intel realsense did the same thing 2 years back, there was ZERO article on it by all most all of the media. why?
