The year 2018 was interesting in relation to the rubber hand illusion subject.

I had participated in an extensive interview study regarding embodiment just a year before [link]. Then, I had been identified as a prosthesis "super user" [link] - these people wanted to investigate my type of "embodiment" through fMRI, but we quickly identified my prosthetic arm design (not my brain) as the key aspect regarding the question of why I have a prosthesis that I can actually use rather than just pose with as so many others. My own view here clearly is that if you are after embodiment, you have to go all Sherlock Holmes, you have to go all forensic, all CSI and all crime mystery: and as in "cherchez la femme" when looking for a motive in a crime, it is "cherchez le bras" when studying embodiment: for all issues that center around prosthetic use, go for the core physical aspects first. There are extremely bad things that may, can, and will happen if you do not make that your real first priority. The "rubber hand illusion" is an extreme variation of body ownership of a rubber hand that does not even touch a person and still that person thinks they are being touched if that rubber hand is touched. The illusion to make an amputee believe they embody or bodily own a prosthetic hand is quite different. But both pose risks, whereas the risk that an amputee faces when getting a prosthetic arm that is integrated into his body image has not been considered yet. My slightly experience based consideration proposes that the body image is tyrannically governed, for good and for bad, and if the prosthetic body part - already starting with bad cards, body image wise - craps out, and it always does so far too often, then it draws the hot red angry ire, the depressed disappointment, the falling apart of the cyborg body, of the amputee - and definitely not the cool "oh a neutral object just disintegrated" that one will wish for from a societal, insurance or repair view. The integration into a body image brings with it that the device becomes subject to totally tyranically governed bodies. When it is difficult enough to make any device ready for real world usage, making it ready to survive tyrannies of that nature will be even harder. I proposed an unforgiving approach to failure testing in a recent paper (link) but I cannot say that paper has been greeted with any enthusiasm by the industry that actually builds prosthetic arm components. Because they get to directly face the anger, hate, and rejection of all the users that they had not informed well of just how fragile their prosthetic arm parts really are (link), and they are in absolutely no position to technically improve these parts. So, manufacturers go into hiding. They do not want many users - they want users that buy and do not complain. The last thing they need is a hard bright unforgiving look into just how bad their engineering is. Every non-user, every rejector, should be cautiously left alone, not recruited to wear a prosthesis - because the risk is considerable (link). Researchers currently have the problem that amputees run away, everywhere (link), also because we are continously treated as mentally incompetent. So in essence, we are a group of people that increasingly realizes the extent to which we are being fooled, being had, told stories, and increasingly, we are getting critical. Potential rubber hand illusion switches, dragged to market to be soldered into prosthetic arms, if ever they are a medical treatment or a part thereof, will have negative effects as well: what are these? What do we know about deeply problematic aspects of bodily ownership? I had been invited to talk about that aspect for a group of people interested in robotic control and user interfaces, on December 7th 2018, in Mannheim (Germany). The presentation that I gave now is typed out here in more detail for further reference.

Rubber hand illusion is an idea that, by and large, was somehow transformed into multi-sensory rubber hand illusion, and they now want to put it into prosthetic arms to make users believe the prosthesis belongs to their bodies.

With that, rubber hand illusion goes to market1)As in: piggy goes to market..

This is not really that fascinating. While I am not interested in prosthetic arms because I find the field fascinating, I have been drawn into the field due to circumstances. And as much as you feel that I am locked into this constraint space of shared idiocies, dreams, hopes and failing hardware together with you, in some type of brotherhood by bad fate, you may also realize you are locked into this with me, as consequence of bad fate. Those then are also circumstances. As I deal with it, you may also have to find a way. If you think that is uncomfortable, send me a mail, so we may talk about uncomfortable a bit.

The ultimate consquence of this piece of reflection is not at all bad, however. We will see just how too much "ownership" has bad aspects as well. It risks to slip prosthetic hands into a domain where it is subject to the most vicious decision making that there is: tyrannic and wilful, impulsive and emotional decision making within one's own very personal domain of body or body image with owned body part dependent urgencies and requirements. To withstand these storms, a  prosthetic arm has to withstand not only the physical requirements of real life use (which it normally does not to a degree that will make your jaw drop), it also has to be acknowledged in that capacity by manufacturers and care-givers, emergency teams or repair units, where none of similarly urgencies are currently provided.

To even reach a level of "tool", to be useful enough to be accepted as technical solution (not as embodied "owned" limb), a typical prosthetic arm may have to undergo a most serious metamorphosis, from commercial parts (link)(link) to tuned and optimized parts (link). If you are in R&D and want to do something good in support of arm amputees, it may be relevant to address actual issues such as failing devices or phantom pain (link), before going all out on a limb and drag ill-defined concepts to a domain where they may wreck more than they really help.

"With that, visitors of the Cybathlon Experience (TM) can test the role of a disabled person" (können in die Rolle einer behinderten Person schlüpfen) (Oral presentation: "CYBATHLON – bewegt Mensch und Technik", 5.15pm–6.00pm, Dr. Roland Sigrist, Cybathlon, ETH Zurich, Raum E 1.2) -- I was there, one among the 8 people that made the audience of this "sold out" Cybathlon talk; amputees are there for "entertainment" (clearly one of the requirements written on a slide in the presentation) (ist es das, was wir als behinderte Personen spielen? eine Rolle, ja?).

After defining a remarkably strange prosthetic arm race, the makers of the Cybathlon 2020 now start to openly bathe us in their pitch-black cynicism.

Why? Pressing question.

So, apparently I had been "identified" as a "super prosthesis user" by a group of researchers. And I was invited to talk about embodiment in context of the "rubber hand illusion" at a user interface or robotic control workshop [link].

So is that what I am: a "user"?

This is a blog post of one of the rare focused and well based scientific journal articles that really explains how real work, body powered and myoelectric arms relate and go together for a unilateral right below elbow amputee in a physically demanding work environment.

The prior presentation of this paper [poster at Cybathlon symposium 2016], which had been more pragmatically worded (with me thinking people would know anyway), this was now written up as article and published. During that process, the reviewers clearly made great points of all kinds of aspects I never knew were not sky clear to everyone.

So maybe, writing a ~ 30 page case study with > 210 references does clarify stuff, at least potentially and for those that actually read it. But possibly, it still requires attention to even just read it.

Knowledge does not come easy, Highlander! (Nakano, in: Highlander III The Final Dimension)

 

If you are more interested in visionary posts, read about the gadget features of the prosthetic arm in Kingsmen: The Golden Circle [link]. And technically, myoelectric control did have it coming. That technology remained uncool for four decades [link].

Ich weiss jetzt nicht, ob Sie das mitbekommen haben. Und ob Sie begreifen was da passiert ist.

Aber am Cybathlon 2016 (Cybathlon, ETH, NCCR Robotics), einer Art Behindertenschaulaufen ohne besonderen  wissenschaftlichen aber dafuer sehr publikumswirksamen Hintergrund [wieso/was:link] mit mehrheitlich durch das Patronat der ETH suggerierten "High-Tech-Hintergrund" gewann ein Mann das Armprothesenrennen, der einen "Hook" trug [siehe detaillierte Griffanalyse, link]. Arschcool, mit 67 ein Senior, dort auch klar der älteste.

Newly appointed Kenneth Pitoskin, professor of engineering, who has a background in surgery, automative design and materials sciences ("one cannot have enough knowhow under the hood"), said that it was time to put the ongoing drama regarding prosthetic arms to an end.

"We will build prosthetic arms that 90% of arm amputees will actually want to wear", he stated.

An upcoming conference seems to hit more precisely than any other contemporary "spectacle" - from body "hacking" (featuring people that quite simply wear stock item devices) over "workshops" where participants are filmed or photographed (but do not get systematic solutions to all aspects that are shown) to "bionic" limb featurettes - the subject at the very core of the current preoccupation of society with disability is not help or support but focus. Support may only be part of making things appear right.

Actual, true, and dedicated improvement or help is not rendered. It is at best shown as sugar coating, thrown in as minimal excuse, offered as pretense, but not made a didactic or technical focus. We now need to delineate real work, real support from sugar coated symbolism that has different goals and purposes.

What is *featured* here - in that conference - is the "spectacle" aspect. What is featured in some odd "bionic" arm workshop is exactly that: they call it "help" - but they invite television to show how good they are and the focus is not on actual function but on "how it looks and appears to the public". They call it "support", but its main feature is a live stream of discussions on media channels all the while the hook remains the best prosthetic ever.

A recent literature review  [1] lists apparent priorities and requirements for prosthetic arms. It mentions the fact that a prior literature review, dated 20 years earlier, already contained some of these requirements.

The necessary conclusions however are not presented; they really boil down to two reasons why that could be:

  • it should be evaluated whether the reasons given 20 years ago and again now just present excuses and not actual requirements;
  • it should be evaluated exactly who focused on practically resolving these issues through research or components, and why, possibly, they failed.
  • it should be evaluated inasmuch academic research now follows its own self-made "requirements" that, really, have absolutely no relevance in everyday life

Let us look at the research assumptions and these apparent requirements, point by point.

Was ist dieses Cybathlon denn?

(Updates zum Thema: hier)

Der Cybathlon 2016 (link) ist ein Versuch, durch Aktivismus der Oeffentlichkeit unter anderem das für die Oeffentlichkeit weitgehend irrelevante (link) Problem der aus Anwendersicht eher leidigen (Problemzyklus - link) Armprothesen näherzubringen - ohne dabei aber jegliche effektive Forschung zur ingenieurtechnischen oder auch sozialen Verbesserung der Stellung Armamputierter auch nur irgendwie ins Auge zu fassen.

Dies verwundert insofern nicht, als die Organisatoren zwar anscheinend die ETH Zürich repräsentieren, aber auf ihrer Publikationsliste keinerlei erkennbare nennenswerte (Sie befinden sich hier auf was für einer Webseite? Was wird hier als "nennenswert" angesehen?) Errungenschaften auf dem Gebiet der Armprothetik vorzuweisen haben und auch im persönlichen Umgang eher wenig aktives freundliches Interesse an der Kernthematik an den Tag legen. Es wäre damit denkbar, dass man sie zu diesem Anlass "verknurrt" oder "verbrummt" hat. Es geht dann allerdings nicht ohne Kritik.

"Man ist da heute ja, äh, sehr weit". (Anonymer Akademiker) 

Der Cybathlon ist finanziert vom NCCR Robotics und stellt damit einen Werbefeldzug für teure - aber nicht "brauchbare" - "Hightech"-Prothesen dar, insbesondere dabei für Forschung auf dem Gebiet der teuren, schweren, aber weitgehend für reale bimanuelle einigermassen schwere - also sog. Echte - Arbeitstätigkeit nutzlosen sogenannten "bionischen" myoelektrischen Prothesen (für beispielhafte Anwendungen und Vertiefung siehe hier).

Dies kontrastiert damit, dass die universitären Forschungseinrichtungen der Schweiz auf dem Gebiet der Armprothetik - darunter verstehe ich diejenige Produktesorte, welche zur Berufs- und Alltagsrehabilitation Armamputierter verwendet wird, welche von Unfall-, Kranken- oder Invalidätsversicherungen übernommen werden und somit den gesetzlichen Anforderungen genügen - nichts (also: nichts) vorzuweisen haben.

From (link):

Thorstein Veblen (1857-1929) is known in sociology for his famous work on conspicuous consumption. He also shares with the classical theorists of his day a focal interest in issues relating to production, especially the contradiction between the potential of industrial production to fulfill society's needs and the interests of businessmen to earn a profit.

The field of prosthetic arms draws up a massive tension field spanning both workmanship and highest leisure class aspirations. To demonstrate credibly that one could be manually able (without having to prove it) currently is the largest leap of faith that companies that sell "bionic" arms require. In return they offer not much.

Fables and fairy tales carry narratives whose symbolism swaps over into apparently secular perceptions [1]. In other words, even societies that claim to be educated, enlightened and secular typically risk to follow myths - unless they take very specific care to not get trapped there.
