Lights, Camera, Action – Some Video Conference tips to make you look better !

Over the last month we have all become regular video conference participants, of course very much par for the course for me but the rest of the family are now taking part in online quizzes, community meetups and have become experts in the use of tools such as Zoom, Houseparty, and even Microsoft teams !

In this short post I’m not going to cover the etiquette of video calling (Mute when not talking and don’t multitask it’s rude) rather offer some pointers to making you look and sound good or at least a little better on screen.

Sounds Good ?

At the very minimum you should be able to improve the way you sound to other people on the call. A common thread here will be to avoid using the inbuilt microphone/camera on your computer and instead something a littlebetter. In terms of the cheap and usually rather hidden microphone on your computer a better replacement would be the simple headphones you might use for your phone (with a 3.5mm jack plug).

Better would be dedicated headset even one with noise cancelling perhaps, the great advantage here is that the microphone ends up a consistent distance from your mouth.

I am a big fan on Plantronics devices, but there are many available at most price points, of course you do end up looking like an Apollo Flight Director at Mission Control but hey that’s not a bad thing.

Plantronics headset, perfect for that Mission Control Vibe !


Having a good microphone does make a big difference to the quality of your interaction of course even if you don’t use video so it is worth making the effort here – if you really want great results then a condenser microphone which produces the warm sound of talk radio is the ultimate upgrade. With a condenser microphone such as the Blue Snowball below make sure you put the microphone into cardioid mode which will pick up sound from directly in front of the microphone only.

Snowball condenser microphone

Most video conferencing systems can cope with the duplex problem of broadcasting what you are hearing and thus creating a nasty feedback issue, however I think it’s always best if you can and especially if you are alone to use a headset/headphones for listening to the call.

Camera – it’s all about the glass

So goes the photographers mantra, it is all about the glass, e.g. the quality of your camera lens. Once again your very expense laptop probably has a cheap inbuilt camera prone to poor low-light performance, motion blur, and noise artifacts – otherwise known as looking rubbish.

The obvious step is to use an external webcam, such as the popular Logitech 920 but these have become very hard to find recently with the unprecedented growth of home working.

The in demand Logitech 920 webcam

There are of course many other webcams from various OEM’s but there is a very good alternative already in your pocket..

Use your phone for video conferences

Your relatively expense smartphone actually has quite a high quality front facing camera for taking all those selfies and combined with computational photography techniques produces excellent results when used as a video conference camera.

Most of the popular video conference systems have a phone app for both iOS and Android and allow you to connect using the same links you would use on your computer. Indeed in most cases you can login on your phone for video/audio calls and at the same time your laptop to follow along with slides etc..

Key to success here is positioning your phone, you don’t want to be holding your phone for any extended period of time and of course want to avoid the “up the nose” camera angle if you can avoid it. The solution is to use a small desktop tripod such as the Gorillapod or Manfrotto mini tripod with phone clamp.

Tabletop tripod

Note : most consumer video conference tools don’t support true HD so it maynot be worth trying to gone beyond 720p 30fps if you have the choice !

Try to position your camera at eye level, so with my example above I would aim to put the tripod on some books perhaps to raise the camera or course a webcam on top of your monitor is perfect but remember to look into it, for other on the calls you donlt want to appear distracted looking at something more interesting (unless of course you are commenting on the quality of the proceedings so far!)

And finally lights !

If you have ever visited a Film set or TV studio you will know the importance of lighting, so even in your home office or bedroom adjusting lighting can make a huge difference to how you look on screen.

Most importantly try to avoid backlighting, your camera will try to adjust exposure as much as possible but if you are in front of a window you will always appear dark almost in silhouette as the bright light coming in from the window dominates. So if possible move the camera so the light is behind it.

If you are using artificial lights the same rules apply, move a table lamp or use the bright screen of your laptop to try and light your face. Ideally you want to have multiple lights to provide both key and fill lights to prevent shadows forming on your face. I use some LED spotlights from Ikea above my monitor to achieve this and the results are quite good.

Lights from Ikea

Here are some examples of the difference lighting makes..

No lighting, lit from window alone…
Single light on face
One Key light on face, and two fill lights removing shadows..

So now when the BBC or CNN skype you for your comments on something or another, and yes they are getting that desperate, you may look as good or better than the host !

You wait ages for a bus and then…

So the saying goes, you wait ages for a bus and then an Open Data project comes along ..

I was asked to speak at the launch event of the UK Dept. of Transport Bus Open Data Digital Services (BODDS) yesterday which aims to provide open data for England complex network of buses outside of London.

As a Londoner I recognise that I am very fortunate having up to the minute information about Transport of London (TFL) Buses available to me on my mobile phone using many popular apps including of course Google Maps. TFL after a lot of pressure developed an API to their data feeds in 2015, and I can now sit of my sofa at home and make sure the express bus to the airport is on time and leave just in time to make it to my local stop.

For most of the country this is not the case, the fragmented nature of bus operations in the rest of England even in large cities made the creation and access to open data about buses overly complex.

The initiative launched yesterday is very important because in providers not only a national platform to share bus information but also tools to allow operators to upload data about their operations including initially schedules but also in due course ticketing and the real time location of individual buses.

Leveling up ?

The opportunity here of course is to “level up” access to information and this is an important step, although I would perhaps have preferred the service to make use of more developer friendly formats GTFS rather than those better suited to Operators, TransXChange and NeTEx. There is a difference between data used in running a Bus network and the information you might wish to publish for journey planning and downstream use.

The role of the developer community will be vital, of course the major information platform companies will in due course consume the data and make it available to their customers but there is a opportunity for a ecosystem of smaller developers to build solutions in the form of apps that link public transport to other local services in a much more integrated way.
Imagine booking a appointment to your local hospital with the appropriate bus journey information to get you from your home to the hospital included along with a ticket delivered to your app.

There is a great deal of talk about Mobility as a Service (Maas) linking different modes of transport together to provide a seamless experience for passengers, convenience is all important and if as the Government hopes people will make fewer private car journeys , alternative solutions need to be as slick as hiring an Uber.

GPS2K? GPS Week Rollover April 6th 2019

Does not quite have the same significance as 31 December 1999, but I’m sure someone in the mainstream press will soon draw the parallels with Y2K with stories of Airliners getting lost or Trading systems failing due to timing errors, April 6th 2019 is the date when GPS systems reset !

Actually for the second time the week code broadcast as part of the GPS signal is resetting back to zero.

The GPS system uses 10 bits to store the GPS Week Numbers starting from 6th January 1980, so every 1,024 weeks (approximately every 20 years), the GPS Week Number rolls over from Week 1,023 to Week 0, this is known as a GPS Week Number Rollover. This has already occured on August 21, 1999 but that was before the explosion in the use of GPS is smartphones, drones, buses etc.

There are efforts happening across industry to make sure that disruption is minimised, but there may be issues with older GPS receivers and smartphones .

With modern connected devices firmware updates can be applied without to much effort, I remember because I’m had one Garmin and Magellan sending out RS-232 cables and CD-ROMS to update their receivers in 1999 !

In summary look out for firmware updates and “Don’t Panic !”

Blog Technology Thoughts

Never have so many people understood so little about so much…

What inspired you as a child ?

A child today hopefully seeing the exploits of Elon Musk and Space-X launching and recovering rockets with showmanship seldom demonstrated by serious rocket scientists may have their interest  sparked in science and technology?

Personally my love of technology came yes from rocket science, but also crucially from growing up during a golden age of science broadcasting in the 1970’s when well informed specialist correspondents were on our TV screens it seemed every day.
Reginald Turnill, Patrick Moore and Raymond Baxter had both huge experience and knowledge in the fields of aviation and astronautics but were also great story tellers explaining often complex issues without the dumbing down so common today.

Reg Turnhill

Raymond Baxter in the backseat of the Harrier piloted by the great John Farley.

For me however the greatest of this generations was James Burke. Watch here his truly breathtaking live commentary of the Apollo 13  re-entry – a masterclass in explaining what is happening to the viewer during an incredibility tense few minutes.

https://youtu.be/A82Ol8J1g_I

I was too young to really remember Apollo 13 however in 1978 James Burke wrote and presented his seminal series Connections to try and explain how technology had come to play such an important part in society, in the first episode of the series he paraphrased Churchill to make the point as relevant today as it was then…

Never have so many people understood so little about so much…

I loved this series, Burke does a masterful job linking technological developments over 10,000 years to explain the modern world – imagine my joy on finding that the series had be re-released last year and is available on Amazon.

Let me show you why I am so gushing in my praise of James Burke…

Watch below perhaps the greatest “piece to camera” every filmed from Episode 8 of the series, here James Burke explains the connection between the invention of the thermos flask and landing on the moon.

Make sure you watch to the very end !

Eat your heart out Brian Cox !

The Romance of Airport Codes

LHR – JFK don’t those six letters cause some excitement to even the most seasoned traveller, there is still just a little romance left in air travel.

Romance here is the “feeling of mystery, excitement and remoteness from everyday life” as opposed to love !

For me part of the romance comes from the Airport codes themselves, those three letter IATA codes are a shortcuts to destinations known and imagined and each have a personal resonance. Many of the codes also have an antecedence that  provide a fascinating window into the early days of air travel.

LHR London HeathRow is both the starting point of most of my travels but also a link back to a childhood spent on the roof of the Queens Building watching British Airways Tridents, VC-10’s and 747 classics departing to destinations I never expected to visit in my lifetime.

Of those childhood destinations and even today New York’s JFK the airport named after president John F. Kennedy was always a destination that sparked my imagination, the destination of those Pan Am Clipper 747s and of course Concorde it was just such a  glamorous destination.  The name of course was the product of tragic history,  the original name of the airport, Idlewild also sounds wonderful but was named after a local Golf Course.

New York’s second international airport, New Jerseys’ Newark has the very functional code of EWR – NEWaRk.

LCY or to those who use if often Lucy

As an alternative to the giant that is Heathrow,  Londons CitY Airport, LCY provides a wonderful contrast harking back to the golden days of air travel when every flight began with that exciting trip up a set of stairs to the aircraft door, Jet-Bridges are just not the same.

LCY is loved by many  is often just called Lucy as a mark of familiarity.

London’s GatWick LGW, Paris Charles De Gaul CDG and of course HELsinki’s HEL are obvious in they derivation, but why is Chicago’s mega airport ORD and Los Angeles LAX ?

The use of Airport codes was originally introduced in the United States for Meteorological reporting  with airports making use of the existing two character city codes developed by the National Weather Service, Los Angeles was LA for example.
It was clear that this system was not going to work with the massive increase in Air Travel after the Second World War so in 1947 a three letter code system was introduced and to pad the existing codes a letter X was often introduced so Los Angeles became LAX, and PortlanD PDX .

A similar approach was taken in Canada where the two letter codes used by Canadian Railways were given a Y prefix so VancouveR’s code VR became YVR, and  QueBec’s code QB YQB.

Most interesting of course are the codes which don’t seem to make sense,  DCA Washington’s District of Columbia Airport  is perhaps not obvious but makes sense but why is the larger international airport in Washington IAD ?  Originally the Dulles International Airport DIA was too similar to DCA so it was simply reversed DIA becoming IAD !

Other codes which don’t seem to make sense are often the result of name changes as Airports have grown or cities have themselves changed name, so CMH the airport serving Columbus Ohio was once just the Columbus Municipal Hanger and of course Mumbai was a city once called BOMbay.

My personal favourite is Chicago’s ORD, very few peoples top airport, we might not feel so negative if it had retained it’s original name ORcharD Field !

The sign of the times..

You might notice a redesign of my site today, nothing major really a little less clutter hopefully, but the reason for the change is really behind the scenes. This site is now using the encrypted version of the web protocol https. Once only a requirement for sites taking payments and banking increasingly all types of websites are now making use of encryption and in the near future the chrome browser will label sites not using https as “Not Secure”.

Personally I think this might be overkill for a site such as this, but I can easily imagine people becoming concerned with such warnings.

A sign of the times…

Swimming against the tide and a tale of cookies 

This must be what a salmon feels like.. A urge to swim against them stream in my case to support Brexit when it seems all of my family and friends are very much in the remain camp.

It’s very easy to understand why, in fact with a campaign hijacked by zeonophobic, lunatic rasists supporting the brexit campaign why would anybody not support remain. Well for me immigration has never really been an issue, I see mostly positives in controlled immigration from wherever, Britian has always been a great melting pot of cultures and has historically benefed from immigration.

Really how can anyone support a position supported by Nigel Farrage, with friends like that…

For me the arguement is perhaps a little more abstract and reflects personal experience working with the European Establishment in Brussels.  I love Europe but I hate (and no that is not over using the term) the institution that is the European Union. You really need to spend a few hours walking around the “European District” of Brussels to understand the scope and aspiration of this purely political institution that is to its very core undemocratic.

To make the point clear I am voting tomorrow not against geography, the UK is and will always be part of the continent of Europe, I am voting against the institution.  Unlike parliamentary democracies new laws are introduced within the European Union by the European Commision an unelected body of beurocrates unaccountable to the electorate of any European nation.  The zeitgeist of the European Commision is clear to create a federal European Super State based on political and economic integration.

The Commision creates directives which are then largely rubber stamped by the other insisituions of the EU, the Council of ministers and the European Parliament who collectively seem to fulfill the role of the UK’s House of Lords. Crucially for the perspective of the democratic process there is no process or mechanism to repeal legislation, which brings me to cookies..

I admit this is a perhaps a trivial example, but it proves a point in May 2011 a directive developed by the European Commision was introduced (Do you remember the discussion or this anywhere.. No ?) which required website publishers to ask users permission to store limited data about their use of website in small files on their computers known as cookies. Now it seems every website you visit pops up an annoying dialogue box asking you if it’s OK with you to store a cookie on your computer. It’s open to arguement if this directive actually prospects users privacy or not, but what’s important is this..

If you wanted to repeal this directive as you believed it was a waste of time and resources, how could you do it ?

In the UK I could talk to my local MP who might begin a campaign is parliament to repeal the legislation, after all the Parliment is the elected legislative instrument of government, within the European Union there is no such mechanism.

At the most fundamental level democracy and national sovereignty is based on the principle that laws should not be made nor taxes raised except by our elected representatives – no taxation without representation. Being able to get rid of our lawmakers is a fundamental democratic right, but one not recognised by the European Union.

If you know me I hope you recognis that I am not a “little englander” and I am certainly not a racist, but I will as a matter or principle be voting to leave tomorrow as is my democratic right.

Workshop on Spatial Data on the Web 2016 at GIScience 2016

I am helping to organise a  Workshop on Spatial Data on the Web 2016 at the 9th International Conference on Geographic Information Science  Montreal, Canada – September 27-30. 2016.

Workshop Description and Scope

In their first joint collaboration, the Open Geospatial Consortium (OGC) and World Wide Web Consortium (W3C) have established the Spatial Data on the Web Working Group. The group aims at investigating and providing guidance for the following challenges (1) how can spatial information best be integrated with other data on the Web; (2) how can machines and people discover that different facts in different datasets relate to the same place or feature, especially when this place is expressed or represented in different ways and at different levels of granularity; (3) and what are existing methods and tools to publish, discover, reuse, and meaningfully integrate spatial data. The group is presently surveying the landscape of existing theories, methods, tools, and standards and is creating a set of best practices for their use.

The GIScience community has a long standing interest and expertise in many of the issues outlined above. In fact, work on geospatial semantics, geographic information retrieval, data integration, and spatial data infrastructures, has been part of the GIScience research agenda for many years. Therefore, this workshop aims at bringing researchers together to (1) discuss typical challenges in publishing spatial data on the Web,

(2) identify best practices,

(3) point out conceptual and theoretical foundations that need to be strengthened or established,

(4) identify common quality issues for existing data and lessons learned,

(5) improve and develop existing geo-ontologies for the semantic annotation of spatial data, and

(6) discuss interface and services that will further improve data linking, sharing, and retrieval across communities.
Topics of interest include (but are not limited to):

  • Semantic Enablement of Spatial Data Infrastructures
  • Quality issues in geo-ontologies and Linked Spatiotemporal Data
  • Experience reports on scalability, discoverability, and so forth
  • Coreference resolution and data linkage
  • New perspectives on semantic interoperability
  • Publishing, retrieving, and accessing sensor data
  • Modeling measurement types
  • Ontologies for space and time
  • Event conceptualization and representation
  • Long term preservation of spatial data
  • Provenance and the publication of scientific workflows
  • Trust and information credibility frameworks
  • Coverages as Linked Data
  • GeoSPARQL in the wild
  • Geo-Data in JSON-LD
  • Geo-data specific user interfaces for Linked Data and beyond
  • RESTful services and Linked Data services
  • Use Cases and Requirements for spatial data on the Web
  • Best practice for publishing spatial data on the Web

Workshop Format

The workshop will focus on intensive discussions and experience reports to identify common challenges and best practice for publishing spatial data on the Web. The workshop will accept two kinds of contributions, full research papers (6-8 pages) presenting new work, surveys, and major findings in the areas indicated above, as well as statements of interest (2-4 pages). While full papers will be selected based on the review results adhering to classical scientific quality criteria, the statements of interest should raise questions, present visions, and point to existing gaps. However, statements of interest will also be reviewed to ensure quality and clarity of the presented ideas. The presentation time per speaker will be restricted to 10 minutes for statements of interest and 15 minutes for full papers. This ensures that there is enough time for discussions, interactions, and breakout group leading to a typical workshop setting instead of a mini-conference. Papers should be formatted according to the Latex or Doc LNCS template.

Submissions shall be made through easychair at https://easychair.org/conferences/?conf=sdw16

IoT Technology Research Award Pilot

There is understandable interest in the Internet of Things fral all people involved with Geospatial Technology,  as after all location is a foundational component for many IoT applications. I still love the fact that my central heating is controlled by a Nest thermostat monitoring the location of my smartphone, making sure my home is not heated unnecessarily, while turning on the heating when I am 30 minutes from home.

Yesterday Google Research announced the Google Internet of Things (IoT) Technology Research Award Pilot,  a programme to provide Research with IoT technology to carry out short term experiments.

Technology available include;

  • OnHub Router, Chrome Boxes.
  • The Google beacon and Physical web platform.
  • Google Cloud Platform IoT Solutions

Submit your proposal by February 29th in order to be considered for a award. We are  looking for projects that offer impact and interesting ideas so priority will be given to research that can make immediate use of the todays technologies.
