The mother’s arm is moving upwards: how are we able to see in her gesture the tender sweetness leading her to caress the cheek of her sleeping child or the inner violence preparing to hit the soldier’s cheek? How can we foresee in the heavy murderer’s hand movement a slight faltering revealing his fragile uncertainty in finishing his task, how can we measure the hesitation of the woman’s arms closing to protect her crying, in resonant dialogue with the bodies moving around her?”

As my ItsMe2 experience surely proves, I like a grandiose megaproject as much as the next man. I am glad therefore to discoverEn-TIme-Ment, which is a Horizon 2020 funded project in Italy whose investigators are not at all humble:

EnTimeMent aims at a radical change in scientific research and enabling technologies for human movement qualitative analysis, entrainment and prediction, based on a novel neuro-cognitive approach of the multiple, mutually interactive time scales characterizing human behaviour. Our approach will afford the development of computational models for the automated detection, measurement, and prediction of movement qualities from behavioural signals, based on multi-layer parallel processes at non-linearly stratified temporal dimensions, and will radically transform technology for human movement analysis. EnTimeMent new innovative scientifically-grounded and time-adaptive technologies operate at multiple time scales in a multi-layered approach: motion capture and movement analysis systems will be endowed with a completely n

ovel functionality, achieving a novel generation of time-aware multisensory motion perception and prediction systems. The proposed model and technologies will be iteratively tested and refined, by designing and performing controlled and ecological experiments, ranging from action prediction in a controlled laboratory setting, to prediction in dyadic and small group interaction. EnTimeMent scenarios include health (healing and support of everyday life of persons with chronic pain and disability), performing arts (e.g. dance), sports, and entertainment group activities, with and without living architectures. EnTimeMent will create and support community-building and exploitation with concrete initiatives, including a community of users and stakeholders, innovation hubs and SME incubators, as premises for the consolidation beyond the end of the project in a broader range of market areas.

This fuller page is even more entertainingly dramatic:

How can we foresee in the heavy murderer’s hand movement a slight faltering revealing his fragile uncertainty in finishing his task, how can we measure the hesitation of the woman’s arms closing to protect her crying, in resonant dialogue with the bodies moving around her?

Of course, I am plotting a way to get on board this particular train.

Vierordt’s Law and experimenting with time

Karl von Vierordt has a relatively short Wikipedia bio (compared, for instance, to this) for someone who pioneered the measurement of blood pressure, the measurement of lung function and – the activity that would link his name with a “law” for posterity, the experimental study of the time sense. Indeed, he seems to have been one of the first experimental psychologists.


This excellent set of slides gives an overview of Vierordt’s career and a very detailed discussion of the time experiments, their methodology, context, and implications. So what is Vierordt’s Law? As stated by Wearden in the talk:

the proposition that short intervals
of time are judged as longer than they are,
whereas long intervals are judged as
shorter, with an indifference point, where
intervals are judged correctly, somewhere
between the two

In 1868, Vierordt published Der Zeitsinn nach Versuchen
– “The Time Sense According to Experiments.” This was not the first study of time perception, but by had by far the most data. Wearden describes Vierordt’s experimental methodology:

The data collected in Der Zeitsinn come from
experimental studies in which Vierordt himself,
or sometimes his pupil Höring, was the sole
experimental participant
• Höring [Vierordt’s student] not only carried out time perception
studies to qualify for a medical degree, but his
thesis work has the oddity that Höring was the
participant and not the experimenter (who was
• The data were derived from very extensive
experimentation, often involving hundreds of
experimental trials carried out over many days

Two taps (on a glass plate) define a target
time interval and the participant must
make a response so that the time between
the second tap and the response is equal
to the time between the two taps

A very full account of the Vierordt effect (perhaps a better term than “law”) is given in Wearden’s paper linked to above. Wearden has an intriguing conclusion:

A potential conclusion is that the Vierordt effects
shown in different tasks don’t actually have any
common cause, and that different processes are
responsible in the different cases

• Here, unusually, theoretical analysis seems to
suggest that things that look the same aren’t
really the same at all, a kind of theoretical
“disintegration” rather than the usual theoretical
“integration” of different phenomena within the
same theoretical framework

He ends with two points that should give pause to those who see the science of today as inherently superior to the science of the past:

You can see that this 19th. Century work, in spite
of some peculiarities, not only produced reliable
data, but also has posed some problems which
are unsolved (and, it seems, quite difficult to
solve) even today in the light of many recent
advances in our understanding of time
• More generally, Vierordt seems to be a pioneer
of experimental Psychology who is unjustly
neglected….until now

The curse of the quick fix

I’ve been reading Simon Garfield’s wonderful book Timekeepers: How The World Became Obsessed With Time. It is a fascinating set of narratives on the modern relationship with time. Towards the end, it slightly turns into a series of lists of conceptual art pieces that sound less Deeply Meaningful than Garfield makes out (oddly reminiscent of Evgeny Morozov’s To Solve Everything Click Here in this regard) and occasionally some of his more jokey passages grate, but most of the time (ho ho) it is a book that makes one see the taken-for-granted of the modern world for what it is. There are very funny passages on time management self-help books and on the world of haut horologie, and extremely thought-provoking ones on our time-poor age (or is it a perception? One of the time management gurus is actually wisest on this…)

Anyway a passage which struck me as especially germane to medicine, health care in general, and health IT in particular was the following – which is actually Garfield citing another author, but there you go:

And can any of these books really help us in these decisions? Can even the most cogently aligned bullet point and quadrant matrix transform a hard-wired mind? The notion of saving four hours every ten minutes is challenged by The Slow Fix: Why Quick Fixes Don’t Work by Carl Honoré. The book set its tone with an epigram from Othello: ‘How poor are they who have not patience! What wound did ever heal but by degrees?’6

The quick fix has its place, Honoré argues – the Heimlich manoeuvre, the duct tape and cardboard solution from Houston that gets the astronauts home in Apollo 13 – but the temporal management of one’s life is not one of them. He reasons that too much of our world runs on unrealistic ambitions and shabby behaviour: a bikini body within a fortnight, a TED talk that will change the world, the football manager sacked after two months of bad results.

He cites examples of rushed and dismal failings from manufacturing (Toyota’s failure to deal with a problem with a proper solution that might have prevented the recall of 10 million cars) and from war and diplomacy (military involvement in Iraq). And then there is medicine and healthcare, and the mistaken belief – held too often by the media and initially the Bill and Melinda Gates foundation – that a magic bullet could cure the big diseases if only we worked faster and smarter and pumped in more cash. Honoré mentions malaria, and the vague but quaint story of a phalanx of IT wizards showing up at the Geneva headquarters of the World Health Organisation with a mission to eradicate malaria and other tropical diseases. When he visited he found the offices somewhat at odds with those of Palo Alto (ceiling fans and grey filing cabinets, no one on a Segway). ‘The tech guys arrived with their laptops and said, “Give us the data and the maps and we’ll fix this for you.”’ Honoré quotes one long-term WHO researcher, Pierre Boucher, saying. ‘And I just thought, “Will you now?” Tropical diseases are an immensely complex problem . . . Eventually they left and we never heard from them again.’”

As my own practice has developed over the years, I have come to a realisation that quick fixes tend to unfix themselves over time, and the quick fix mentality carries a huge cost over time.

Here is Honoré’s TED Talk. Garfield has a very entertaining passage in the book where he talks at a rival of TED’s, which has a 17 minute limit (TED has an 18 minute one)
