CHI Academy … a Faustian bargain?

I am on a short excursion from walking Wales to CHI 2013 in Paris.

Last night I was inducted into the SIGCHI Academy. No great fanfares or anything, just a select dinner and a short ceremony. I thought Gerrit, who is current SIGCHI chair would look good with a sword dubbing each person, but instead just a plaque, a handshake and a photo or two by Ben Shniederman, amanuensis of CHI.

I feel in two minds. On the one hand there are many lovely people in CHI community, and I spent a great afternoon and evening chatting to folk including Phillipe Palanque, Mary Czerwinsky and Hiroshi Ishii over dinner. However, ACM and to some extent SIGCHI often appear like the Star Wars imperial forces, intent on global domination.

The CEO of ACM did little to dispel this at the opening ceremony this morning.  He spoke of ACM’s international aspirations and praised CHI for regularly having its conferences outside of the US.

Now ACM is the de facto international computing organisation and CHI is the de facto international conference in human–computer interaction, but by virtue of the fact that they are the US ones.  In principle, IFIP and Interact are the international computing organisation and HCI conference respectively, as IFIP is the UNESCO founded body of which ACM and other national computing bodies, such as the BCS in the UK, are members.  Interact, the HCI conference sponsored by IFIP is truly international being held in numerous countries over the years (but I think never yet the US!); in contrast having approximately two out of three conferences in the US is laudable, but hardly the sign of a truly international organisation.

So, is the ACM an originally US organisation that is in the process of slowly becoming truly international, or is it part of more general US cultural domination?  Although probably neither are completely accurate, at present there seems to be significant aspects of the latter under the guise of the former.  In a way this is, in microcosm, an image of the same difficult relationship between USA and UN in other areas of international affairs.

And by joining the SIGCI Academy am I increasing the European presence in CHI and thus part of the process to make it truly international, or selling my academic soul in a Faustian bargain?

wonder women

As I started to prepare for the Wales walk I learnt about Anne-Marie “Arry” Beresford-Webb, who in her DragonRun1027 was first to traverse the new Wales Coast Path and existing Offa’s Dyke long distance path all around Wales.  Only Arry was not content to walk around Wales, as I will do in a few weeks, but she ran it, 39 days, a marathon distance every day, all in support of Velindre Cancer Centre.  I thought Arry was Wonder Woman – just absolutely amazed, in a year of amazing Olympic successes, still my hero of the year if not the decade.

I thought this must be the summit of achievement, what could equal that.

Then Rob Styles (@mmmmmrob) shared a link on Twitter to One MIllion Lovely Letters.

Since she was eleven, Jodi Ann Bickley (@jodiannbickley) has been leaving notes “between text books, on buses, in libraries and as I got older in pubs, restaurants … anywhere I thought that maybe someone might need a little bit of cheering up, reassurance or just a reminder that actually they are pretty lovely” because “everyone deserves to know that they are thought of and they are loved. Even if it is by a complete stranger.“.  And now she is offering to write to anyone, beautiful hand written letters, full of love, to anyone, any of the seven billion strangers we all have in this world.

This would all be marvellous enough on its own, yet when she describes her lifelong project of lovely note leaving she goes on to say “… and as I got a little older in doctors surgeries and hospital beds“.  It turns out that the new turn to letter writing is because she has been recently “blessed with a lot of time“, and this blessing, not a lottery win leaving her a lady of leisure, or retirement at the end of her years, but a debilitating illness at the age of 24.

I am sure Arry’s ultra-marathon running is based on years of physical practice starting with small runs and building up to her epic achievement, gradually exercising muscles and joints so that when called upon to work in extremes they are ready.  Not that the work was not hard and painful, not that feet did not bleed and muscles ache, but a body prepared through small things for the great things demanded of it.

It sounds to me that in spirit and personalty,  Jodi has had just such exercise, creating a habit of joy-giving in small things so that when the big challenge came, while no less painful in the body and soul, she is ready, not just to endure, but to make it a blessing for others.

I am amazed and awed.

I myself have been blessed to know many wonderful women, not least my wife and lovely daughters.  And I can only thank God that in days of cynicism and depression, hardship and crisis, there are those who in different ways rise as heroes to inspire us all.

get fit on Tiree

Today is the winter 10K run on Tiree.  It has been organised by Craig Watson, one of the airport firefighters on Tiree, in aid of the “Michelle Henderson Cervical Cancer Trust”.  It is looking a lovely day for it, although there will be a chill in the air under the clear blue winter skies.  I saw the plane land earlier and I know there are folks coming over both on the plane and the ferry to take part.  Personally I have trained with my usual level of foresight doing my first run for 6 months last Tuesday :-/

Of course this is not the only event of its kind on Tiree there is the annual 10k, which I sadly missed this year as I pulled my Achilles tendon :-( , a round island sponsored cycle in March this year, and ‘Team Tiree‘ get off island for various events through the year.

Although this winter 10K is organised by Craig, many of the island fitness activities are due to Will, runner of ironman races and organiser of the Costa del Muscle training week I took part in in August and other regular island fitness activities (from 9 to 90s!).

Next year Will is branching out and organising residential training camps, one in Majorca (for the warm weather wimps) and one in Tiree next March. The latter starts the week after the next Tiree Tech Wave, so you could come for a weekend of sitting around hacking technology followed by another of shedding flab and toning muscle!

The war in the west

Just got back from the book launch for “Tiree: War among the Barley and Brine“.  Organised by An Iodhlann and the Islands Book Trust.

Mike Hughes, one of the authors, gave a talk and there were ex-service men connected with Tiree and their families present.  One man was the son of the pilot of one of the two Halifaxes which crashed into each other over the airfield on a cloudy day – a father he had never met as his mother was only 4 months pregnant at the time.

I hadn’t realised that it was from Tiree that the weather reports came in that set the timetable for D-Day.  The meteorological squadrons are unsung heroes of the war, flying far out into the Atlantic, in conditions where all other planes were grounded, to get the long-range weather data that is so easy to gather now-a-days from satellites.  Sadly the airman who had made the crucial weather observations for D-Day did not survive the war dying in that same Halifax accident over Tiree.

Neither had I known that Tiree was to be the staging post for the withdrawal of Winston Churchill and the Royal Family had the worst happened and the the German’s invaded Britain.  So, before it withdrew to a government in exile in Saskatchewan, the last outpost of British sovereignty would have been … Tiree.

First version of Tiree Mobile Archive app goes live at Wave Classic

The first release version of the Tiree Mobile Archive app (see “Tiree Going Mobile“) is seeing real use this coming week at the Tiree Wave Classic. As well as historical information, and parts customised for the wind-surfers, it already embodies some interesting design features including the use of a local map  There’s a lot of work to do before the full launch next March, but it is an important step.

The mini-site for this Wave Classic version has a simulator, so you can see what it is like online, or download to your mobile … although GPS tracking only works when you are on Tiree ;-)

Currently it still has only a small proportion of the archive material from An Iodhlann so still to come are some of the issues of volume that will surely emerge as more of the data comes into the app.

Of course those coming for the Wave Classic will be more interested in the sea than local history, so we have deliberately included features relevant to them, Twitter and news feeds from the Wave Classic site and also pertinent tourist info (beaches, campsites and places to eat … and drink!).  This will still be true for the final version of the app when it is released in the sprint — visitors come for a variety of reasons, so we need to offer a broad experience, without overlapping too much with a more tourism focused app that is due to be created for the island in another project.

One crucial feature of the app is the use of local maps.  The booklet for the wave classic (below left) uses the Discover Tiree tourist map, designed by Colin Woodcock and used on the island community website and various island information leaflets.  The online map (below right) uses the same base layer.  The map deliberately uses this rather than the OS or Google maps (although final version will swop to OS for most detailed views) as this wll be familiar as they move between paper leaflets and the interactive map.

   

In “from place to PLACE“, a collection developed as part of Common Ground‘s ‘Parish Maps‘ project in the 1990s, Barbara Bender writes about the way:

“Post-Renaissance maps cover the surface of the world with an homogeneous Cartesian grip”

Local maps have their own logic not driven by satellite imagery, or military cartography1; they emphasise certain features, de-emphasise others, and are driven spatially less by the compass and ruler and more by the way things feel ‘on the ground’.  These issues of space and mapping have been an interest for many years2, so both here and in my walk around Wales next year I will be aiming to ‘reclaim the local map within technological space’.

In fact, the Discover Tiree map, while stylised and deliberately not including roads that are not suitable for tourists, is very close to a ‘standard map’ in shape, albeit at a slightly different angle to OS maps as it is oriented3 to true North whereas OS maps are oriented to ‘Grid North’ (the problems of representing a round earth on flat sheets!).  In the future I’d like us to be able to deal with more interpretative maps, such as the mural map found on the outside of MacLeod’s shop. Or even the map of Cardigan knitted onto a Cardigan knitted as part of the 900 year anniversary of the town.

     

Technically this is put together as an HTML5 site to be cross-platform,, but … well let’s say some tweaks needed4.  Later on we’ll look to wrapping this in PhoneGap or one of the other HTML5-to-native frameworks, but for the time being once you have bookmarked to the home page on iOS looks pretty much like an app – on Android a little less so, but still easy access … and crucially works off-line — Tiree not known for high availability of mobile signal!

Walking Wales

As some of you already know, next year I will be walking all around Wales: from May to July covering just over 1000 miles in total.

Earlier this year the Welsh Government announced the opening of the Wales Coastal Path a new long distance footpath around the whole coast of Wales. There were several existing long distance paths covering parts of the coastline, as well as numerous stretches of public footpaths at or near the coast. However, these have now been linked, mapped and waymarked creating for the first time, a continuous single route. In addition, the existing Offa’s Dyke long distance path cuts very closely along the Welsh–English border, so that it is possible to make a complete circuit of Wales on the two paths combined.

As soon as I heard the announcement, I knew it was something I had to do, and gradually, as I discussed it with more and more people, the idea has become solid.

This will not be the first complete periplus along these paths; this summer there have been at least two sponsored walkers taking on the route. However, I will be doing the walk with a technology focus, which will, I believe, be unique.

The walk has four main aspects:

personal — I am Welsh, was born and brought up in Cardiff, but have not lived in Wales for over 30 years. The walk will be a form of homecoming, reconnecting with the land and its people that I have been away from for so long. The act of encircling can symbolically ‘encompass’ a thing, as if knowing the periphery one knows the whole. Of course life is not like this, the edge is just that, not the core, not the heart. As a long term ex-pat, a foreigner in my own land, maybe all I can hope to do is scratch the surface, nibble at the edges. However, also I always feel most comfortable as an outsider, as one at the margins, so in some ways I am going to the places where I most feel at home. I will blog, audio blog, tweet and generally share this experience to the extent the tenuous mobile signal allows, but also looking forward to periods of solitude between sea and mountain.

practical — As I walk I will be looking at the IT experience of the walker and also discuss with local communities the IT needs and problems for those at the edges, at the margins. Not least will be issues due to the paucity of network access both patchy mobile signal whilst walking and low-capacity ‘broadband’ at the limits of wind-beaten copper telephone wires — none of the mega-capacity fibre optic of the cities. This will not simply be fact-finding, but actively building prototypes and solutions, both myself (in evenings and ‘days off’) and with others who are part of the project remotely or joining me for legs of the journey1. Geolocation and mobile based applications will be a core part of this, particularly for the walkers experience, but local community needs likely to be far more diverse.

philosophical — Mixed with personal reflections will be an exploration of the meanings of place, of path, of walking, of nomadicity and of locality. Aristotle’s school of philosophy was called the Peripatetic School because discussion took place while walking; over two thousand years later Wordsworth’s poetry was nearly all composed while walking; and for time immemorial routes of pilgrimage have been a focus of both spiritual service and personal enlightenment. This will build on some of my own previous writings in particular past keynotes2 on human understanding of space, and also wider literature such as Rebecca Solnit’s wonderful “Wanderlust“.  This reflection will inform the personal blogging, and after I finish I will edit this into a book or account of the journey.

research3 — the practical outcomes will intersect with various personal research interests including social empowerment, interaction design and algorithmics4.  For the walker’s experience, I will be effectively doing a form of action research!.  This will certainly include how to incorporate local maps (such as tourists town plans) effectively into more large-scale experiences, how ‘crowdsourced’ route knowledge can augment more formal digital and paper resources, data synchonisation to deal with disconnection, and data integration between diverse sources.  In addition I am offering myself as a living lab so that others can use my trip as a place to try out their own sensors and instrumentation5, information systems, content authoring, ethnographic practices, community workshops, etc.  This may involve simply asking me to use things, coming for a single meeting or day, or joining me for parts of the walk.

If any of this interests you, do get in touch.  As well as research collaborations (living lab or supporting direct IT goals) any help in managing logistics, PR, or finding sources of funding/sponsorship for basic costs, most welcome.

I’ll get a dedicated website, Facebook page, twitter account, and charity sponsorship set up soon … watch this space!

Tiree Touchtable – the photos

At last, the photos from the week making and installing the Tiree Touchtable.  You can see all the photos on Flickr, but here is small selection:

The main components – projector, Kinect (on top of projector) and mini-Mac:

Tiree Touchtable installed

It is there!

Suspended high in the ceiling of Tiree Rural centre, a slightly Heath Robinson structure (pictures to come) that powers Tiree’s first public touchtable.

It was a long day, starting at 9:30 in the morning and not finishing until after 9pm in the evening.

The first few hours were simply getting the physical supports in place — with special thanks to Steve Nagy, who fixed the major elements, in particular the awkward tasks of suspending a two foot square (60cx x 60cm) platform that had to be positioned to lock into four steel rods, all while standing on a ladder 20 foot in the air.  Then a long task up and down ladders, huddled over computer screens, adjusting extending, puzzling over strange banding effects that we eventually concluded were artefacts of low level processing with the Konect’s image depth algorithms.

A squadron of flies constantly circled in the projector beam, their shadows suggesting maybe a virtual ‘squat the fly’ game could be developed!   There had been a sale in the cattle ring on Friday, so the flies presumably a remnant of that … but curiously, in the absence of cows or sheep, it was the Konect sensor itself that was their focus of attention, occasionally landing on one of the lenses — maybe they were attracted by the Infra-Red transmitter – a whole new area for etymological research.

The team cleaning the cattle ring, watched and chatted, and then returned with a spotlessly cleaned (it had been covered by ‘you know what’!) sheet of white wood to act as a table cover.

And now, well there is still work to do: permanent electric supply up into the rafters (to replace the temporary tangle of strung together extension cables, that hung from the ceiling during testing), improvements to the algorithms to extend the range to allow the sensors to be as high as possible (to avoid being hit by the next passing ladder), and of course applications to run in the space.

But we feel the back has been broken and a good weeks work.

Costa del Muscle – athletic spirit hits the Hebrides

It has been a great (albeit exhausting) week.

Will Wright, fresh back from Spain where he was competing in the Long Distance Triathlon World Championships1, has been working hard to make the rest of Tiree, well, if not as fit as he is, at least fitter then they were before! Continuing the Spanish theme he called it, ominously, “Costa del Muscle”.

Each day last week, twice a day at 9:30 and 5:30, on the sun-drenched mahair of Sandaig, looking out over basking sharks leaping in the seas towards Skerryvore, twenty Tirisdeach2 gathered, from 10 year olds to those in their 60s, from svelte teenagers to those, well, carrying a mite more weight.  The passing minke whale or grey seal, if they had looked towards the shore, would have seen flaying arms in sweat drenched t-shirts, and perhaps catch Will’s cheerful voice, rising over the crash of breakers and faint sound of wheezing breath, announce, “nearly finished the warm up”.

I want to pay more tax too

Some of the ‘super rich’ in the US are beginning to ask publicly why it is they pay so little tax.  For those of us less rich, but still with above average salaries, perhaps we should be asking the same.  In the UK the effective rate of tax is 32% for those on average pay and 40% for those on high pay, hardly a progressive system.  Yes government, please tax the super rich more, but tax me properly too.

I have just have read Stephen King fantastic article “Tax Me, for F@%&’s Sake!1 where he joins Warren Buffett in questioning why he, as part of the super rich, does not pay more tax.  He does give to charity, but argues that that this is not the same as paying tax, which is crucially abut citizenary.  This all falls out from statistics that show the richest in the US end up paying a far smaller percentage of their income than the average citizen.  Effectively King argues that the issue here is not about entitlement or rights, but responsibility.

King is talking about the super rich in the US and similar statistics in the UK show the richest 10% paying only marginally more taxes than the poorest 10%, and certainly less than the average tax payer.

However, the same arguments also apply to those who are not super rich, but on the better end of the income scale –  including me.

In recent years I have cut my income substantially by choosing to work part-time in order to (try to!) do more personal research, still some of my income falls into ‘higher rate’ tax — so by that measure I am well off2.

You might think that being in the higher tax threshold means you pay a lot more tax; after all the basic rate tax in the UK is 20% and the higher rate is 40%.  You might think that, but think again!  Even without tax avoidance measures used by the very rich or the fact that the poor tend to end up paying more indirect taxes such as VAT (purchase tax) and duty (on alcohol and fuel), still my marginal rate is only slightly higher than that of basic income.  I pay an effective marginal rate of 40%, but those on lower income in reality pay 32%, not the 20% that it says ‘on the tin’.

The reason for this is National Insurance.  For those not on the UK, this is an additional tax, started in 1911 and expanded in the 1940s to pay for health, pension and other welfare provision — just as you might take out a private health insurance, or pension, national insurance was intended to be a sort of pooled insurance arranged by government.  However unlike private insurance, it has always been redistributive — the rich pay more, but do not get proportionally higher benefits.

In the UK since the Thatcher years, but continued by subsequent Labour governments, there has been a gradual shift from ‘in your face’ income tax, to less visible taxes, notably National Insurance and VAT.  In 1978 National Insurance was at 6.75% (on income over a lower threshold) and the standard rate of VAT, paid on most basic goods and services you bought in shops, was 8%3.  Currently the equivalent figures are 12% for National Insurance and 20% for VAT.  That is the combined effect of these less visible taxes has more than doubled from 14.75% in 1978 to 32% today4.  Because these are flat rate taxes, they hit the poor as much as the rich.

However, it is worse than this first appears.  National Insurance has a maximum cut off point.  Above a certain point, you pay no more National Insurance … and crucially this point cuts in just before higher rate tax starts.  This means that in one’s pay cheque if you are earning an average wage you pay 32% of every additional pound in tax, whereas if your income is higher, over £40,000 or so, you pay 40%.

I’ll say this again, as it always seems unbelievable — in the UK, without any additional measures to reduce tax liability, the real difference between basic rate and higher tax is just 8%.

If then the person earning £15,000 buys a basketful of ordinary VAT goods, out of the 68p they have left they pay over 13p VAT, whereas the person with £50,000 income out the 60p in the pound they have left pay an additional 12p.  Adding the effect of VAT that makes the effective total rates of tax on an ordinary shopping basket at 45.6% for basic rate tax payers vs 52% for those on higher income.  In fact, even this is a little of a simplification, as some goods are zero rated (principally food) and some have additional duties (principally alcohol and fuel), but in fact this tends to make things worse as typically richer households have spending patterns that have a lower proportion of VAT and duty.

Like the US, the UK system is not progressive; so with Stephen King I say, “I want to pay more tax5.

In particular, take the lid of National Insurance, make me pay full National insurance on all my income.  At a conservative estimate this would be equivalent to the revenue of 5% VAT6 — if we all paid full NI, then either spending cuts could be less draconian, or the VAT rate could be cut by 5%, either of which would have a dramatic effect on those at the bottom of society for whom the pressing problem is not getting the best offshore tax break, but finding the next meal.


  1. Which he wrote in April, so I am a bit behind! [back]
  2. Although you do have to be careful in using higher rate threshold as meaning ‘well off’, as the UK system is incredibly family-unfriendly.  Because tax is on an individual not household basis, if a couple earn £20,000 each they pay very little tax, but if one is not working — in particular if engaged in full-time child care — and one is earning £40,000, then that is heavily taxed.  This anomaly became apparent recently when the government proposed removing child-benefit, one of the few universal benefits, from those where one of the parents is paying higher rate tax. Strangely, when it comes to welfare benefits households become the unit! [back]
  3. See UK Tax History for historical rates of National Insurance and VAT. [back]
  4. See HM Revenue & Customs site for current NI and VAT rates. [back]
  5. And yes, I know that I can give to charity and indeed do tithe through Charities Aid Foundation and make other payments, but, as King argues, that is NOT the same as paying taxes. [back]
  6. I recall doing the calculations for this when the new government put up VAT some years ago, it was hard to get detailed figures for higher rate tax earnings, but made this estimate based on lower bounds of various brackets. [back]
