Wormholes, WebRTC and the implications of algorithmical analysis

James Batchelor is Founder and Chief Executive at Alertacall, an organisation which uses neat technology to deliver services which increase human contact with people at risk and are used to improve the lives of many thousands of vulnerable people. Prior to that he was involved in the creation several ventures in the internet service provision, internet retail, telecoms, recruitment and telecare sectors. James has been an ipcortex customer since some of our earliest days and is one of those people who, every time I have the pleasure of chatting to him, I always walk away with a valuable bundle of unique insight. I posed the question to James about the technology impact of WebRTC, and this is what he came back with…

WebRTC meets wormholes

On a long-haul flight in 2001, with the occasionally pungent aroma of reconditioned air in my nostrils and the drone of Rolls Royce engines through my headphones I was transported for a few hours not only to USA – but in to an alternative future. I had the immense pleasure of having time and little else to do but read a novel and a science fiction one too.

The story I read, “The Light of Other Days”, is centred on the discovery of wormhole technology which can be used to pass information instantaneously between points in the space-time continuum. The technology is commercialised by a global media company and used to create the “wormcam” which allows for anything anywhere to be viewed with profound implications for privacy.

As I ponder the applications and implications of WebRTC, and explore its own wormhole like qualities, I wonder whether there are similar impacts for humanity and how the absolute digitisation of our communications streams – coupled with the massive computing power now at our fingertips – could impact upon our own privacy in novel and unexpected ways.

My own company Alertacall is particularly interested in understanding how patterns in the way people communicate with us can indicate a change in their “need”. This is with the positive goal of helping our older customers get the help they need before a situation escalates and becomes materially more difficult to manage. And, as our future products and services start to use WebRTC and other similar communications technologies I wonder what additional data we’ll have at our disposal.

Real-time analysis

I’ve long hypothesised that computers should be able to detect from cameras and other input devices subtle things about human physiology that the human eye cannot, but only had clear evidence of it after stumbling across the fascinating TED talk See invisible motion hear silent sounds.

This talk demonstrates the possibility of detecting heart rate with nothing more than video, by analysing the microscopic movements in our skin caused by pulsating arteries. I wonder how long it is before a methodology to determine skin temperature is devised, or what can be inferred by knowing how quickly someone breathes, blinks or swallows?

In 2012 the mathematician Mr Max Little announced that Parkinson’s symptoms can be detected by using algorithms that analyse voice data. There is also Voice Stress Analysis, which can indicate a range of emotional states including the detection of whether someone is potentially lying. What else could be inferred from a “call”?

But what specifically has this got to do with WebRTC and similar stacks? I suggest that the incredible proximity of these communications streams to silicon provides an unprecedented opportunity to develop applications that exploit all of these methods for causes good and bad. For example: imagine if calls to emergency services were prioritised using real-time analysis of video and voice, where the person most likely to be having a heart attack is answered first.

Also, imagine a world, in which the person or organisation you are in a call with has installed one of the dozens of analysis applications that are likely to emerge – and can infer huge amounts about your physiology. “Mum, I’m absolutely fine” the daughter says to her mother, but moments later the concerned mother’s machine tells her it’s simply not true with a simple Chrome plugin.

We’re tremendously excited about the applications we can build with WebRTC to connect with our customers and to connect our customers to each other – but live in constant wonder about what opportunities will emerge.

My Bandwidth is Precious (GET OFF IT!) — or — Autoplay Angst

Bandwidth usage of streaming video from in page ads uses up data bundle for those people with low data caps on their service – such as satellite based broadband

Oh joy. I keep falling over sites that autoplay videos, and some — I’m looking at you, Facebook — do not appear to have a simple option to switch off this, er..uh, ‘option’. Ignoring some of the real basics are the spurious claims that our bandwidth is being protected with such tricks as  video ceasing to play when the screen is scrolled down, or “it only works when you are connected to wifi”.

First, the video by playing has already consumed some of my precious bandwidth. You can’t just mine these bits at home, you know; data bits are a commodity that have to be bought and paid for. I will press the Play button if I want a video to play, otherwise autoplay is actually forcing me to (a) view something I probably don’t want to view, and (b) causing me to pay for the privilege of viewing that something I don’t want to view, which is on the whole, utter dross. And it is usually advertising dross at that, funded by “someone” to reach an unwilling and hence unresponsive audience. You, oh advertiser, may have money to chuck down the proverbial drain, but many of us out here who are paying to receive your video message do not!

Click Here, Lindsey

Second, what on earth has a wifi connection got to do with it all? Apart from moving the video dross onto a marginally cheaper option than mobile (i.e., by using my fibre, cable or landline-based broadband tariff instead), someone still needs to pay for the bits received. And for those on satellite dishes it makes no difference how video is configured to play, the consumer is going to be extremely cross to find their monthly data allowance munched through regardless of the pain this can cause to the unwillingly disconnected.

29% of USA ISP traffic is Netflix

Interesting talk from Nina Bargisen of Netflix. What surprised me was the chart she showed of the main traffic drivers on ISP networks in the USA. Netflix comes out top, representing 29% of all traffic carried by ISPs in the US. YouTube is only 15% of traffic with http coming third at 11%.

The thing to consider here is that as people move to higher quality video -3D,  Super HD, Ultra HD (4k) and ultimately 8k format the percentage of traffic that is video is clearly going to grow. Also clear is that this move to higher bandwidth video is going to seriously drive bandwidth requirements – both in operator networks and at the home broadband level.

Netflix recommend that you need 12Mbps bandwidth to carry 3D and between 5 and 7 (optimally) for Super HD. In the UK you would therefore be able to stream one 3D video or two Super HD, assuming an average download bandwidth of 14Mbps. 4k video will need 15Mbps per stream.

If for the sake of argument we assume that Netflix and YouTube represent all the video traffic in the USA then as 4k comes on stream and the bandwidth required to support it therefore doubles then video could well end up at almost 90% of all internet traffic. I realise that other applications will also grow their bandwidth needs but I don’t think I’m a million miles off the mark.

It’s coming folks. Better get your broadband speeded up. Pic below is of the chart shown by Nina at the conference.

PS no idea why people watch TV – the only good stuff on is Time Team and Storage Hunters and I’ve already seen Mary Poppins quite a few times.

Bowater on the Warwick Summer Party

There comes a time on a Friday afternoon where a man’s thoughts turn to the Bank Holiday ahead. This weekend I am off on stag weekend in London taking in the Premiership Rugby Final between Leicester & Northampton followed by the England v Barbarians match on Sunday. No doubt we will also take advantage of being in London to pursue some cultural activities the details of which have yet to be disseminated to the travelling party.

In the meantime I have been given permission to show you a video. It has nothing to do with the stag weekend although there is a fleeting bit of rugby action near the beginning.

The video has been produced by the heir to the Davies title (currently 2nd in line seeing as my dad is still going strong and I am still around obv) in between taking his final exams at Warwick University and is an advertisement for the end of term celebrations. It stars Aaron Bowater who was the joke candidate in the elections for the Warwick Students Union President. During the elections my son, Tom, produced a number of promotional videos that received over 40,000 views on YouTube. This one is well worth watching.

Fearghas nods off

Many of you will know Fearghas McKay as a solid hard working lad who is thoroughly dependable and very knowledgeable about his subject. Such is his commitment to his job that he often works through the night at home and then turns up for a full day in the office the next day.

All this hard work does eventually take its toll.  I mischievously filmed the lad sleeping like a baby at UKNOF24 held at Timico yesterday.  Poor old Fearghas completely missed Jesse Sowell of MIT’s retrospective on the WCIT meeting. Ah well. Lucky for him he wasn’t snoring when I was filming.

I gave out some wonderful Timico Megamugs at UKNOF but I do have a few left and seeing as it’s Friday afternoon I’m going to have a caption competition. Lets have some suggestions for captions to accompany this video.

Storage needs on the up

I did some backing up last night. As well as using Google+ for photos I store them on two hard drives kept at separate locations – one at home and one in the office.

The drive at home is 500GBytes and only has a few tens of gigs of space left. The one at work is a TeraByte palm drive and has plenty of room on it.

You may have noticed a bit of a theme to posts in recent weeks/months relating to the growth in storage requirements based on people taking more and more photos. As my home drive was starting to fill up I thought I’d revisit my usage pattern (if that’s the right way of putting it).

The chart below shows the amount of storage needed for photos and videos on a year by year basis. The early years are just noise. 2007 looks like a bit of an aberration – a rush of blood/new camera/special occasion maybe.

From there on there is a definite trend appearing. Remember that we are only half way through 2012 and I haven’t had my summer holiday yet. I am using the same camera technology thisyear as last with the exception that the Galaxy S3 has the burst mode which is naturally going to generate more Bytes.

Snooker, chainsaws and high voltage cattle prods & O2 4G LTE trial

In an idle moment last night whilst simultaneously watching the snooker and browsing Twitter I asked the important question of our time. Does anyone have a favourite agricultural equipment? This was totally random but it was amazing how many people responded – all blokes.

Rob immediately came back and said “David Brown tractor” as his dad used to build them. That’s cool especially as it turns out David Brown used to own Aston Martin (hence DB5) and Lagonda. I wonder how many gears that tractor has.

I thought plough had a certain earthiness to it. Note the video at the bottom of this post was taken in October 2010 just outside Lincoln (England) at the World Ploughing Championships. Check it out and note the O2 LTE upload medium.

Video games killed the art of conversation – spot the game megaprize competition #TimicoDC

Timico datacentre logoWe had a hugely successful data centre opening event at Timico yesterday – 210 customers, prospective customers and business partners came along and, if I say so myself, had a great time (and were impressed 🙂 ). More on this as soon as I’ve assembled the photos etc – I’m on the move at the moment.

In the meantime I have a little prize competition for you. At the back of the lecture theatre (conf room, call it what you will – it had more than 200 odd people in it), just for fun, we had a range of “antique” video games, consoles and computers on show.

There’s a bottle of champagne1 and a mug for the first person to correctly identify all the different systems shown in the video below (Timico staff not eligible here as they will have been able to view the kit yesterday).  Note no apologies for the title of the post. It is partly true and the internet is now doing its best to finish the job.

testing testing can you understand me at the back?

Here for your delectation and delight are some experimental video shorts. I’m looking at ways of moving the blog content on and this is one of them.  These videos are approximately 60 seconds long, that being the attention span (max) of many people using the internet these days. This is being somewhat unfair as readers of trefor.net spend on average 90 seconds on the site with some days hitting 4 minutes.

The videos are unedited – single take recordings. I don’t want to spend hours making each video but I wouldn’t mind receiving some feedback on the content and the unstructured/unedited approach. More videos banged out quickly is better in my mind.

I used used a Logitech HD Pro Webcam C910 and also wouldn’t mind hearing what you think of the audio quality.

There are six of them and you don’t actually have to listen to them all though doing so does buy you brownie points and we all know what points mean 🙂 Following some useful feedback I have also put links in for the moment as well as the embed code.

Video killed the radio star

I think I might have mentioned my appearances on BBC radio 🙂 . Well now I’m producing a video. Actually the video is being made by some final year students from Lincoln University media department and it is part of a series of shorts that the students are producing for Timico.

We are quite lucky to have a top level media facility such as Lincoln University on our doorstep. Their studios are the envy of the BBC- I kid you not.

To date any video I or anyone else at Timico has produced has been pretty much an experimental amateur affair. Now we are doing it properly. Each video has a production team of 4 people. I just need to get a Director’s chair with my name on it and turn up at the right time for makeup.  Of course I’m sure I’ll have a script to learn as well!

Timico is a sponsor of Lincoln University and I am not only looking forward to seeing the videos but presenting a prize at the end of the year. I’ll also show the vids when they are finished sometime in the spring.

Video competition

Following on from a post I made in June regarding Polycom putting over a hundred videos on YouTube I have started exploring this myself.

The video at end of this post is my first post on YouTube (timicocto) where I have uploaded details of a video competition that we are running at Timico in July. The hope is that we will get some good material to post on the company website.

Ultimately we will be looking at broadcasting live and this is a step towards that goal.

I’ll report back on how it went when it is all over and done. Sorry – the competition is open to company employees only.
