Tele2: How a Raspberry Pi kit helps people to live the life of a complete stranger

How a Raspberry Pi kit helps people to live the life of a complete stranger

Tele2 is one of the more intriguing projects we’ve come across. It was a custom Raspberry Pi electronics kit worn by various interesting people from around the world. Each person wore a GoPro Hero 5 and Røde Video Microphone to capture a first-person view of what they were seeing and hearing.

More intriguingly, the system collected data on each personality’s heart rate and sweat level.

All of this data was used to measure the emotional state of the person, which was relayed to the viewers using visual effects layered on top of the audio and video. Brain sensor (EEG) data was translated into warmer or cooler video filters to represent the person’s emotions.

Tele2: Making virtual worlds with a Raspberry Pi

Tele2 Wearer

We caught up with Alvin Groen, the director and designer of the Tele2 project, who dreamt of building a piece of equipment that “changes our perspective.” We were interested in learning more about how the Tele2 project was put together.

The Tele2 project is named after the Swedish telecom company that sponsored the project. “They were launching a new 100GB data plan and wanted a project that required high data bandwidth,” recalls Alvin. With funding underway, the Tele2 project was born.

“In Sweden, a lot of discussion around connectivity tends to be negative,” says Alvin, “especially when it comes to controlling our exposure to media.”

Alvin wanted to alter the outlook people had on other lives. “Each person was chosen because they have a big following online, or they have an interesting life,” explains Alvin. They included Simone Giertz, a robot maker from Stockholm, Joel Kinnaman, an actor from Vancouver (and star of the RoboCop reboot), and Noor Daoud, a female drift racer from Dubai. An impressive collection of folk.

Each of the personalities was hooked up to the Tele2 equipment. The team broadcasted nine live streams in five countries during a two-month world tour. “We measured the personalities’ heart rate, emotions, and sweat level,” using a Skin Response Sensor and Muse headband (choosemuse.com). Then, using WebGL and web audio technology, they translated the data live into audiovisual effects.

Tele2 kit and custom backpack

The team built a custom backpack using a 3D printer for each personality. The rig included a Raspberry Pi hooked up to an e-Health v2.0 board. The Raspberry Pi collected and processed all the video, audio, and sensor data.

Camera footage went to a colour grading box in the backpack. This was “fine-tuned for each location”, and the video and audio was streamed live via a Teradek VidiU wireless HDMI video encoder.

The built-in wireless features of the Raspberry Pi 3 made it a good fit for the project. “The built-in Bluetooth chipset, wireless networking, and the fact that you can use a pretty standard flavour of Linux right out of the box made it very easy to work with,” says Alvin.

“Since all the other equipment was rather bulky, size wasn’t an issue either,” he adds. “The toughest challenge was trying to figure out if we could get the Muse headband to communicate directly with the Raspberry Pi, since the official Muse SDK wasn’t released for the ARM architecture.”

The project was a huge success, with hundreds of thousands of people tuning in to see what it’s like to be somebody else. Viewers could click on cheers and give feedback to the wearers. Overall, Tele2 was a very interesting combination of health sensors and live video streaming.

    Why do you not add extra sensory perseption to be in the real world experience more of it with iR vision layer and uv layer, the ability to be in another person’s kit and make a merge with stacket rasperrys making a merge of both worlds with safe space blending gps it so it is not available outdoors too switch… Add more senses through the gpio like magnetic compass (in a studies this was described as having a completely new enhanced sense of where one was after just 1-2 weeks… Sweden wich I live In promised 1gigabit free optic internet to the citizens almost 20 years ago …we where going out to be in touch with the real possibility of future technical advance… Now we are moving to be a completely new enhanced mutant of censured homogeneous horror , in a country rated to be the hardest to find a friend there have to be something incredible to expect of entertainment for everyone and free. We are forced to pay money if we own a reseiver that’s capable of looking at 2 channels, the very same that makes it so to receive all other ones. They say this is a completely perfect country to be in, but I’m not allowed to fly a drone with a camera FPV system without getting license and otherwise​ this probably cost money. Why can’t they just build up a completely new enhanced sense of looking at reality making it more accurate warning us if a car is approaching at a completely crazy speed and so on. It’s not hard to do this it’s even fun and existing. My point is RPi is a great platform to play with the , Oboard is a better asoc right now I’d you need it to be at least smartphone fast, the last point is that the ideas here are funny and interesting for health but health might be to become exited of seeing the uv Spectra of flowers blending in and out and watching bees follow visible fermone trails… Many in a study hard work hard world environmental stimulation may be a good place to add extra life and to give lonely people a virtual augmentet reality friend , that may be a more sensible future where we evolve ourself within at least to safe standards like uv/ir-addon augvr and compass as free for all who asks for it… Ilive in a dystopia compared to what I was promised by a completely different generation who just didn’t get it and many in mine still don’t but I’m sure the next will …not by perfect standards but better than the current status we are forced to see….
