2017.58333333...: Slightly-Post-Mid-Year-Review

I should really have done this at the end of June, but between exhibiting Engineering the Imagination and preparing for the SUITCEYES meeting at Leeds, it all went a bit... manic.

Anyway: let's see how I'm doing:

On the Blog

I set three goals for the whole of 2018:
* At least 24 posts (pro-rata, this would be 12 to the end of June, 14 to the end of July)
* At least 2 posts per month.
* At least 1 non-review post per month.

I was on 9 posts at the end of June, and had caught up to 13 at the end of July. (EDIT: I tried to get clever by posting this on the morning the 1st of August so this would be my August non-review post, but Blogger seems to have recorded it as 31st July - it must run on US time, I guess? Anyway, I've actually just caught up at the end of July and now need a new non-review post for August). So I'm currently 1 post off my target, but I failed to post at all in June,  missed having a non-review post in April, and this will be my fifth post in as many weeks, so I've fallen into the feast/famine pattern I wanted to avoid.

That said, I think the tick-tock approach is working well, and for the most part I'm on schedule, so I'll stick with it.

Research
* Deliver the SUITCEYES and APEX projects.

I'm doing these - we've recruited staff for SUITCEYES, begun design and experimentation so things are happening. APEX is virtually finished.

* Submit at least five grant applications as either PI or Co-I.
I'm on two at the moment, with two more in the pipeline. So, I need to find project number five!

* Submit at least two *more* papers to high quality journals (resubmitting the ones under review don't count).
Ouch. I'm on zero, at the moment. There are two in draft, though, so I think I'm on target.

* Get the MagONE force sensor incorporated into FATKAT.
Done! Ish. Laidlaw Scholar Jamie Mawhinney has put the hardware and software together. There's just the small matter of calibration...

* Get BIGKAT (the new generation of PSAT that incorporates prehensile as well as postural measures) up and running.

Done! PhD student Awais Hafeez has done sterling work on getting this working and benchmarked. Field tests to begin this autumn... You'll notice that I'm taking the credit for a lot of other

* Continue to develop the grip model to address feedback and corrections: This, having no direct funding attached to it, remains the poor cousin to other work
Done, in the sense that I have continued to develop it, rather than it being finished, but we've demonstrated predictive value of the model, and I have a fancy new way of extracting features. All hush-hush til the publications come out, though...

Other
*  Make some inventions: And get back into Leeds Hackspace while I'm at it. I haven't been for about eighteen months.
* Formulate a reading list for the Engineering Imagination.
These are two that got dropped last year, and I think they're going to get dropped this year, too. It's shaping up to be a busy autumn with everything that's going on. Well, we shall see...

Month in Review: July 2018

July (like most months, now I think about it) is a funny month. A sort of liminal space: it doesn't have the teaching rush of May or June, and it isn't as full of family holidays and childcare commitments as August. Nor, however, is it a doss: especially if you don't want to be crunching come September.

I always set myself the target of having my handouts ready for the end if July. I haven't *quite* hit that target,  but I'm pretty close (I have a new lecture this year, which still needs tidying up). The rationale behind this is to keep me from fiddling, and allow me to write my exam before term strikes. I also have to double the size of my Mechanical Systems module for 2019-20 delivery, which seems a whole away, but the module proposal needs to go in in November, and if I don't want to be writing it and an exam while trying to teach, both need to be done this summer. It makes for a much smoother transition between term and "not term": it gives me more research time during term, and avoids wildly swinging between teaching and research. I prefer it this way.

The big news this month was the second SUITCEYES consortium meeting, which took place in Leeds. It was good: though we communicate frequently by email, Slack, and teleconference,  you can't beat face-to-face meetings.

One of the main aims of the meeting (other than planning - and the reason for holding it in Leeds) was to introduce consortium members to the Social Model of Disability. After all, Leeds is one of the leading Centres for Disability Studies. We had a session from Leeds Disabled People's Organisation on the Social Model itself, from Professor Anna Lawson (Director of the Centre for Disability Studies) on Human Rights and Legal Frameworks, and from Deafblind UK on working with people with Dual Sensory Loss. All valuable sessions, and very helpful for the stage of the project as we prepare to launch into user engagement and technical development.

Then we had a couple of extra days with Astrid Kappers (from VU Amsterdam), Nils-Krister Persson and Li Guo (both from Borås), to follow up on the thermal testing we did in April. This time we were looking at more conventional vibrotactile feedback, trying out different patterns. A good session, and we're going to be using this to start more formal data gathering in the autumn.

Other than that, both my Laidlaw students have finished - a 3-axis version of FATKAT based on the MagONE is now ready for calibration (barring a bit of resoldering to improve the part fit), and we've been designing some VR experiments on interaction with objects.

We've now rebranded from CAP (formerly PACLab) to ICON (Immersive Cognition), which has included some changes in the way we manage the group and seem (touch wood) to be working.

Now August beckons - always an even odder month. I'm off for half of it with annual leave, so we'll see how fitting in all the work that needs doing (that new handout, the exam, and planning that new module... Oh, and running SUITCEYES and writing publications, and at least one large grant proposal that needs doing) goes...

Engineering and the Posthuman

I'm co-writing a piece with Stuart Murray that touches at the end on posthumanism and engineering design. Writing across disciplines is always a challenge - so bound is each by its conventions and expectations - but there is nothing quite like it for really proving a collaboration! This is some way out of my comfort zone - you may recall I have some unfinished business with Rosi Braidotti's The Posthuman from 16 (!) months ago - so I thought the blog would make a good place to work through some my thoughts.

Caveat Lector
I say this often, but the warning still holds: I'm an engineer trying to describe areas way beyond my competence. What you're getting are my raw, crudely thought out reflections on encountering new material: not the carefully constructed argument of an expert. Feel to free to put me right.

Posthuman vs Transhuman
A complexity in dealing with the "posthuman" is the sheer range of ways that the term is used. One  of my main lessons from reading Braidotti is that "posthumanism" is not about being post-human or the next stage in evolution or the perfecting of the species, or moving beyond human (that being the domain of transhumanism, and there I think the relationship of such engineeres bodies to Engineering is quite clear). Rather, it us about moving beyond Humanist philosophy. That being the case, does it have any relevance to engineers?

A Note on Terminology
Given the variety of meanings for "posthuman", and the fact that while we might talk about "posthuman engineering" and "transhuman engineering", they don't really compare with "human engineering", I'm going to come up with a clunky solution and use the phrase "humanist", "posthumanist" and "transhumanist" when describing styles of engineering. You will also notice a lot of use of quotation marks. Often inconsistently. That's how much I'm struggling with the terminology here.

Beyond Human
One of the major tenets of posthumanism  seems to be the breaking down of barriers between human, animal and machine. This can be captured in the whole question of "Why should bodies end at the skin?". By this token "human" isn't an ideal to be refined and perfected (as it is in Transhumanism, I guess?), but a boundary to be questioned. Note also assumptions about who is allowed to be "fully human", whether humans are rational, 

This Deluezian style of inquiry is one I have written about before, and the notion of system boundaries as something socially negotiated in any engineering project rings true. And there are times when the skin is a useful system boundary, and times when it is not. The question that is interesting is: what happens when the system boundaries are negotiated without engaging users in that discussion? 

This is where we get into criticisms of "fixing" people. Or coming up with complex solutions to problems where simple solutions already exist. Or failing to consider the broader sociotechnical issues - who maintains the device when it goes wrong? What happens if it becomes obsolete? But recognising that a person should be considered as part of an "assemblage" (to use the Deleuzian phrase) and considering the social environment around them is hardly a radical new approach to design or Deleuzian experimentation. And I doubt it would qualify as being a "posthuman" position.

Does the Posthuman have any value in the discussion of assistive technology and prosthetics? Or does it run on a parallel track to engineering, with the two never actually intersecting? The difference between "humanist engineering" and "transhumanist engineering" seems reasonably clear: the former sees the human as a given; a constraint to be designed around, outside the scope of design; the latter sees the human as part of what is being designed, with form and structure, function and material all up for debate and redesign. What would the difference between "humanist engineering" and "posthumanist engineering" look like?

Is it an ethical position? Consideration of robot and animal rights, for example? Shifting away from viewing humans as the rightful rulers of the world who can do with it as they will to seeing us as only one part of the world, with corresponding moral obligations? Is it something else? And wouldn't that apply to almost everything, not just to medical devices? Of course, if one adopts the Social Model of Disability, then questions of access pervade every engineering decision. Who gets to use this device, and who is excluded? This brings us back to the idea of "selective enabling", and questions of what obligations the engineer has to society. But would this make inclusive design an example of "posthumanist engineering"?  That doesn't feel quite right.

Of course, one of the interesting properties of labels is that as a concept becomes more commonplace, it becomes absorbed into mainstream terminology. With time aspects of "posthumanist engineering" could just merge into the accepted definition of engineering. The notion that designers need to avoid toxic materials, or think about how products will be disposed of, or consider the security of their devices move from being unusual ideas to just part of what it is to design.

Can Engineering be Humanist?

It only makes sense to talk of "posthumanist engineering" if engineering can also be "humanist". Still, I'm not entirely sure I would recognise a "posthumanist" or "humanist" design if I saw them. Or if designs can be "humanist" or "posthumanist" for that matter. We rub up against the dual nature of technical artefacts: it is very hard - maybe impossible - to reverse engineer the intentional nature of a product from its physical nature. Since humanism and posthumanism describe philosophies, they would manifest as different approaches to design decision-making (applying different values, even if the underlying process didn't change). Different approaches to design can converge on very similar - or even identical - outcomes. The can diverge wildly, as well, and changes of intent will change the "best" design for a given circumstance. It might be the case that actually, posthumanist designs end up being very different from humanist designs. It's just that it might not. Would the design process even be different? Or just the values underpinning choices? How would you know if your design process took a posthuman approach? This, by the by, probably applies to all engineering done across disciplinary boundaries. How would you know from a product whether it had been engineered ethically? Or critically? Or with the Social, rather than medical model of Disability in mind?  

An interesting comparison (well, I think it's interesting) is whether the same difficulty would apply to recognising  "transhumanist" design. There is a difference in intent (which would be difficult to confirm from the end product), but would there also be a difference in the scope and material of designs? Would "transhumanist" engineering be visible in terms of the incorporation of the human body as part of the material being designed? But then, would we class tissue engineering or the reconfiguration of muscles in amputees to improve the reading of EMGs for prosthetics as "transhumanist"? Probably not - again, the difference lies in intent.

That said, the phrase "Humanist Engineer" is not one that I have originated. You can find several references to it: a Twitter account, an interview with Lewis Cerne of New Relic, a talk to the Royal Academy of Engineering from Janusz Kozinski of the New Model in Technology and Engineering. The thing that these have in common is a need for engineers to be "more human", take a broader view, and have a focus on the needs of humans, rather than just on developing technology.  Of course, here the term "humanist" is probably used in the sense of a non-religious person who seeks to "live a good life"  and " work together to improve the quality of life for all and make it more equitable" (see Humanists UK), which I'm not sure is quite the same thing that posthumanism critiques.

I mean, I think that telling an engineer working on prosthetics that "your users are no less human because they have had an amputation!" would probably elicit a puzzled look and the response "Why would I think they were any less human?". Though that in turn might leader to a debate about why they are designing prostheses - which is probably better taken by those who use them than by me. I guess, though, we run back to the matter of intent: if you're designing prosthetic hands (say) because anyone who doesn't have two hands is broken and needs to be restored to normality, then that's a different case from designing them because amputees find them a useful tool for picking things up.

Of course, perhaps the "posthuman" becomes more interesting in the context of artificial intelligence (AI) and robotics, where blurring the boundary between human and artefact becomes more significant. Are robots slaves, or do they have rights? And if robots have rights, then do other machines? Do we have obligations to the machines that we create? And if so, where is the line drawn? Do we have a moral obligation not to injure the pavement by walking on it? I don't think anyone would make that case. Would we only have such obligations to "strong" AI? 

The short answer is, I'm just not sure. Which is a slightly unsatisfying point at which to end this blog post, but greater minds than mine are grappling with these issues.  Perhaps a better question is: are these questions relevant to engineers while they are doing engineering?  As distinct from being relevant to engineers because they are relevant to everyone?

In Summary

So, after that long and rambling thought-piece: what (if anything) can we conclude? 

First and foremost that the effects of any philosophical intervention would have to be sought in the process, rather than the product of engineering. 

Following from this, then we might ask: what would be different about this process?  The steps involved might even be the same. It would be in the values and attitudes brought to design decisions. 

And what would be different about those values? Here the amorphous nature of the posthuman causes the detail to become blurry. Would it be more respectful of life as a whole? More reflexive, identifying and challenging biases? More open to exploring broader horizons? More focused on the needs of users rather than theoretical ideals? All of these have potential in helping to head off Colingridge's dilemma, and a countering the problem of microscopic vision - but none of these would be unique to the Posthuman.  

But maybe that doesn't matter. Maybe the value of engineers engaging with the Posthuman is that it provides an avenue for raising these issues, rather than a magic bullet to solve them.

And that feels like a positive conclusion to me, so I think I will stop there.

Month in Review: June 2018

Well, the wheels are definitely off in terms of my two posts a month target! We'll see if I can catch up an do four posts in July!

It goes without saying that June was a busy month. It's not quite as brutal as May (particularly since I'd finished my marking), but it's exam board season. We're much more efficient than we used to be (what was about 14 hours of meetings has been trimmed to 7 or so), but the deadlines are absolute. Things have to be ready for the external examiners come hell or high water (did I say that in my last post? Well, it's true!). All marks need to be finalised, students with coursework extensions' work marked , marks uploaded and coursework  samples selected.

Of course,  it was made extra busy by the British Academy Summer Showcase preparations, and prep for New Designers and the upcoming SUITCEYES consortium meeting taking place in Leeds this month. Also our taught MSc conference, where we spend a day with every taught postgraduate presenting their dissertation. Busy and hard work, but a great way of finding out about the range of projects going on.

I have two Laidlaw Summer students, one returning to work on FATKAT (the Finger and Thumb Kinematic Assessment Tool), and another working on haptic feedback in VR and SUITCEYES. The Leeds SUITCEYES team is finally complete, with Zhenyang Ling (known as Yang), Research Fellow in Haptic Communication and Navigation starting.

There are some big changes afoot for CAP (the Cognition-Action-Planning lab I am part of), as we do our annual stocktake of where we are and where we're going. The most obvious change is our increasing focus on Immersive Cognition. It doesn't mean a lot of change in what we do, but reflects the fact that our work is increasingly oriented around Virtual, Augmented or Mixed Reality. The lab will be rebranded as ICon (for "Immersive Cognition" - ICogn seemed a bit opaque). It's exciting times with Leeds' new centre for Immersive Technologies coming online.

July promises to be another busy month! We have the aforementioned SUITCEYES consortium meeting taking place in Leeds, we are now ready to start conducting our first interviews, and with Yang getting stuck into the technology side,  we're really hitting our stride. And, of course, teaching prep. I always aim to have handouts ready by the end of July, so I can print in good time and can't make last minute changes.

Busy times - still,  it keeps me out of trouble, eh?

British Academy Summer Showcase

I nearly titled this "Too busy to blog", since it's been a fiendishly heavy duty month. That's partly due to exam boards - this is always quite a busy time of year, since marks need to be in and confirmed for the external examiners' visit come hell or high water - but this year things have been busier than usual, thanks to the upcoming SUITCEYES consortium meeting here at Leeds next month, and in particular the British Academy's first summer showcase, where Stuart Murray, Sattaporn Barnes (of Eatfish Design) and I were showing off our "Engineering the Imagination" project, and the resulting artificial hands that we developed.

It was a great time - if very busy (we spent about thirteen hours each over three days on our exhibition stand). Lots of good conversations! But let me back up a little: what is Engineering the Imagination? After all, you might have spotted a certain similarity to the title of this blog...
Engineering the Imagination is a year long project funded by the APEX scheme, intended to bring together sciences and the humanities. This particular project focuses on the design of artificial hands, and in particular the consideration of non- functional hands: which is hard for me, as an engineer, to get my head around. I suspect that Stuart and I have very different takes on the project.  For Stuart, I think it's all about hands as metaphor, ideas of deficit and difference: what makes a hand 'disabled'? Why do we design artificial hands to be like 'normal' hands - and what makes a hand 'normal'? What do hands signify, and how does this change if the hand is artificial? Stuart would be better placed to explain his views.

For me,  it's about exploring ideas about what we can do with artificial hands. Why not have a sixth finger? Lights? If we can't replicate the human hand,  are there other ways an artificial hand could emote? Or function?

The designs we were showing off reflected this. There was the Empathy Hand: a powered hand that could adopt a range of poses; the three-fingered "Mudd Hand", based the hand of our collaborator Andy Mudd (who was also there to show the original that inspired it!) and the six-digit "Lunate Hand" which had a second thumb, inspired by the work of Clifford Tabin, and his comments about extra thumbs.

You can see images of all three, and the stand (for context!) below! Also, though we didn't have it ready in time for the Showcase,  the Empathy Hand now has a light-up palm which, when pressed, causes the hand to light up and close in response. It was a great three days, but I'm aware that I'm already five days late with this update, so I think I'll call it a day there, and let you enjoy the pics!



The Stand as a Whole!
A three-fingered artificial hand, shown with fingers closed.
The Mudd Hand: A three-fingered hand designed to mimic that of our collaborator, Andy Mudd

A six-digit hand: it has the normal five digits, plus an additional thumb extending from the palm to oppose the middle finger.
The Lunate Hand: A six-digit hand adding an extra thumb from the palm. Named Lunate because we reckon that the thumb is attached roughly where the lunate bone is in the interest, and it sounded swish.


An artificial hand shown in an open pose, with fingers splayed.
The Empathy Hand: An artificial hand that can open and close in response to trigger signals. It is designed to be modular so that parts can be interchanged. Adding a light-up palm for example! At the moment it just has a range of poses triggered by button presses.


An artificial hand shown in a closed pose, grasping another hand from the exhibition.
The Empathy Hand getting to grips with the competition!
