Time for life-sized videoconferencing?

Is everyone sick of seeing friends and co-workers compressed into a portion of an already-small monitor?

The only good video conference experience that I have had was back in 2000 in Australia. A university with two campuses used the rear wall of a lecture room as a life-size window into a room that was about 20 miles away. People in that remote room appeared life size on the rear wall. The data link speed was, I’m sure, nowhere near as good as the standard fiber-to-the-home services today. The projectors could not have been as good as today’s projectors. But it was surprisingly natural to converse with people who seemed to be just on the other side of the wall.

Multi-city law firms today often have advanced systems. A huge direct-view TV (85″?) on one wall of the room in New York can show what is going on in a similar room in D.C. It doesn’t seem as effective as the system that the Australians had back in 2000, though, because the people who appear on the screen are not as big as the people who are live in the room (or as “live” as anyone can be who is working on a patent infringement question!).

Back in 2003, I wrote up an idea for a infrastructure that would enable a person to work side-by-side with an assistant in another part of the world: “it is as if a wall in one’s office is opened up to the assistant’s office thousands of miles away”. Why not build home offices like this as standard? A window in front and video walls left and right. If the plague returns, everyone who currently works side-by-side in a Silicon Valley coding plantation can go home and still work side-by-side with at least two co-workers at a time.

I’ll cut and paste the research idea from 2003…

Americans make expensive employees. Productivity is measured as economic output per dollar of labor input. In the absence of technological advances, the only way to improve labor productivity is to move the job to a low-wage country. Pairing every American office worker with an assistant in a low-wage English-speaking country (or a low-wage part of the US) would be an excellent way of boosting productivity without exporting jobs, assuming that an effective coordination system can be constructed.

The Labus Novus coordination system will comprise the following components:

  • a life-sized two-way video conferencing system; it is as if a wall in one’s office is opened up to the assistant’s office thousands of miles away
  • an information system that records everything relevant to the high-wage worker’s job, including facts, reference material, contacts, correspondence, appointments, and relationships among these items [like a more sophisticated Microsoft Outlook]
  • robot arms and other robots within the high-wage worker’s office that can be manipulated by the low-wage worker, thus enabling the assistant to pull folders from file cabinets, position papers on a desk, etc., from the other side of the planet

Current state-of-the-art video conferencing systems require 6 Mbits of point-to-point bandwidth. Thus the requirement of extremely high quality video conferencing implies the need for research in video analysis and compression, network protocols and routing, and semiconductors and optics for very bright images.

[Ooops! This is rather unfortunate to read, 17 years later! 6 Mbits?!?]

Outlook-on-steroids might sound straightforward but doing the job right can be as challenging as all of Artificial Intelligence. We are building support for a computer-mediated assistant rather than attempting to build a fully automated personal cognitive assistant. This does not reduce the difficulty of achieving a complete solution but it does increase the utility of an incomplete solution.

A desire to give the assistant the ability to manipulate physical objects half a world away (telepresence) justifies research in broad areas of robotic actuators and sensors.

Funding Possibilities: Phone companies are logical sponsors for this research. Telcos built a tremendous amount of network capacity in the 1990s but then neglected to offer any services besides voice communication, thus resulting in falling prices and bankruptcies. Only about 10 percent of the fiber installed through the U.S. is actually being used. Continuously active high quality video conferences have the potential to consume all of currently unused bandwidth in the networks.

Note that the system could be used domestically, yoking together a worker in an expensive crowded place such as New York City with an assistant in a low-wage uncrowded place such as Iowa.

  1. An organization called Shared Studios makes what they call “Portals,” shipping containers that have systems in them for doing life-sized video conferences:


    People rave about how great the experience is.

  2. Working in 3 startups now, all relying heavily on tools for remote working, even though 2 of them required us all to be in the office staring at our screens, the tools have evolved to text based communication & most of silicon valley has already adapted.

    You situation as a teacher addressing a classroom, a witness addressing a courtroom, & a pilot flying a helicopter probably does require a more comprehensive avatar. You need appendages to grab the cyclic, change radio frequencies every 5 seconds & press foot pedals.

    • Thanks, Stephan: Why isn’t it more popular? Even the richest law firms still seem to favor the “stuff the people on the other end of the line into a smallish video window” model. And nobody has their home set up this way, as far as I have seen, though it would be nice to interact with friends and relatives (instead we see them on a phone screen!).

    • I used to work on Cisco telepresence suites. They were awesome – you sat at a conference table, in front of 3 HD screens that projected another room with an identical table in another building, with all the cameras set up so you could look someone in the eye. The suites started aat $250.000, as I remember.

    • Why isn’t this more popular? I can only offer speculation.
      1. Price, not only in terms of the equipment, but also in term of real-estate. For a good telepresence system, one needs to install sound baffling, microphone arrays, furniture that forces people to sit at the camera focus, and so forth. That means a dedicated room optimized for video conferencing and nothing else.
      2. The (initial) incompatibility between the three major vendors (Cisco/Tandberg, Polycom/Telesuite, and Sony). This has gotten worse with the growing popularity of walled garden technologies including Skype and Zoom.
      3. Video conferencing is an acyclic industry. Over the past 10 years or so the technology (and the networks) have become good enough to allow for a compelling user experience, but few were investing in this because users preferred physical travel.

  3. Phone companies? Other than building out technologies built by others they have done nothing. A related example here in Canada. Rogers, Bell, Cogeco and Shaw are all telephony, mobile, cable TV and Internet providers.

    As netflix grew to subsume all of pay TV and all the Internet bandwidth any or all of these players could have built a ‘Canadian Netflix’. They have access to all the Canadian Content and a ton of other media that have seperated Canadian distribution rights. They have access to infinity money to invest and there is ample technical capability in Canada.

    Yet.. they completely failed with a couple of lame attempts and never going as far as they could have.

    BBC is the same. A huge library of content that is popular around the world but its locked down so no one can really access it so it leaks out onto other channels. For years they had the most popular TV Show in the world, Top Gear. They entirely failed to capitalize on that …. they could have built an Internation BBC netflix. They have access to infinity money to do so and state apparatus to make it happen.

    Skype meantime, disrupted the world’s telephony businesses only to fade to the lame buggy unreliable dumpster fire it is now. They had effective video conferencing working ages ago.

    • I second Viking’s suggestion to use Jitsi. It’s free, it’s open source, and it works well. I’ve used it for groups as large as fifteen people without problem. And because it typically doesn’t use a central server to transmit video — just to connect the calls — latency is lower, which means that people don’t end up talking over each other as much.

  4. Hah this is awesome – you gave a talk at UNSW when I was a student there in early 2000s – we sometimes did that but may have been another uni.

    I remember you bright three cans of Diet Coke to fuel you threw the talk !
