Instructable: One-Touch Keypad Masher

One-Touch Keypad Masher

It’s been a long time since I last wrote an Instructable, but as I’ve resolved that 2009’s going to be a year where I start making things again (2008 involved a lot of sitting, reading and annotating, and in 2007 most of what I made was for clients, and thus confidential), I thought I’d write up a brief (10 minute) fun little bodgey project which has, very marginally, boosted everyday productivity: the One-Touch Keypad Masher.

Wasting valuable seconds typing in a code every time you need to open the door?

This little ‘device’ streamlines the process by pressing the right keys for you, and can be hidden in your palm so you simply mash your hand against the keypad and – apparently miraculously to anyone watching – unlock the door in one go.

Time to make: Less than 10 minutes
Time saved: About 30 seconds per day in my case; your mileage may vary.
Payback time: 20 days, in this case

(There’s a (weak) correlation with some of the Design with Intent topics, since it could be seen as a device which allows a user to interact with a “What you know” security measure using a “What you have” method. At some point in the near future I’ll be covering these on the blog as design patterns for influencing behaviour.

It’s also a kind of errorproofing device, a poka-yoke employing specialised affordances. If used, it prevents the user mistyping the code.)

The Instructable is also embedded below (Flash), but for whatever reason there are a few formatting oddities (including hyperlinks being ignored) so it’s easier to read in the original.

The Hacker’s Amendment


Congress shall pass no law limiting the rights of persons to manipulate, operate, or otherwise utilize as they see fit any of their possessions or effects, nor the sale or trade of tools to be used for such purposes.

From Artraze commenting on this Slashdot story about the levels of DRM in Windows 7.

I think it maybe needs some qualification about not using your things to cause harm to other people, but it’s an interesting idea. See also Mister Jalopy’s Maker’s Bill of Rights from Make magazine a couple of years ago.

Springer delivery note
Springer delivery note

This delivery note from Springer informs me that the book I’ve bought “must not be resold”. Good luck with that. So have I bought it or not? Or have I bought a licence to read it? What if I give it away?

Many companies would love to be able to control what users can do with things they buy, or with information after someone’s learned it. We know that, and we know that, fundamentally, it’s not going to work. You can try and shape behaviour, to guide users into helping themselves, but nonsense such “end-user licence agreements” for books has no mechanism of enforcement, and offers no benefit to the reader if he/she obeys it anyway.

How valid, legally, are any of these “post-purchase conditions”, anyway? Surely the first-sale doctrine or its equivalents allow users to re-sell items they buy with impunity?

Sarah Burwood: Tumble Sums

Tumble Sums by Sarah BurwoodWe’ve covered teaching machines and programmed learning textbooks a few times on the blog, and I’ll admit to a general fascination with analogue computing and similar ideas, ever since reading John Crank‘s Mathematics and Industry as a teenager, after finding it in a skip (dumpster) along with a lot of other very interesting books*. It was the idea that you could build an analogue electrical circuit, with resistors, capacitors and inductors, to model many physical phenomena (gravitational fields, etc), which really intrigued me, brought up in a world where computation was presented as entirely digital.

But I digress. A lot of the fascination comes from seeing a different way to explain a concept to someone else: a structured, alternative form of learning or understanding a problem, which is, somehow, immensely satisfying. There’s always the glint of a possibility that if we could find different ways to explain difficult or complex subjects, more people might be able to understand and appreciate them.

Sarah Burwood, a graduating Industrial Design student showing her work at Made in Brunel this week, has created Tumble Sums, a ‘Child’s Mechanical Visual Calculator’:

Tumble Sums by Sarah Burwood

Helping children understand fundamental mathematical principles, Tumble Sums is a calculating tool which visually shows a child how an answer is being reached. Calculations are solved in a physical way, based solely on mechanical operations. Tumble Sums focuses on an understanding of the way children think, their mathematical understanding and the psychology behind these aspects.

It looks to be beautifully machined from acrylic sections, and that height alone makes it extremely imposing. Imagine one of these at the back of every primary-school classroom!

This concept of making hidden processes visible in order to aid the construction of the user’s mental models is something that will, I think, be an important component of lots of more advanced interfaces in the years ahead, particularly in areas where, fundamentally, we’re bad at understanding the consequences of our actions (environment, health, finances). It’s maybe allied to constructionism, though by no means the same idea.

*Incidentally, the morning I first turned up at Brunel again as a PhD student, I sat in the wonderful garden John Crank had created, reading Vance Packard’s The Waste Makers, waiting for the doors to the building to be unlocked.

Smile, you’re on Countermanded Camera

We’ve looked before at a number of technologies and products aimed at ‘preventing’ photography and image recording in some way, from censoring photographs of ‘copyrighted content’ and banknotes, to Georgia Tech’s CCD-flooding system.

Usually these systems are about locking out the public, or removing freedoms in some way (a lot of organisations seem to fear photography), but a few ‘fightback’ devices have been produced, aiming to empower the individual against others (e.g. Hewlett-Packard’s ‘paparazzi-proof’ camera) or against authority (e.g. the Backflash system intended to render a car number plate unreadable when photographed by a speed camera). The field of sousveillance – lots of interesting articles by Régine Debatty here – is also a ‘fightback’ in a parallel vein.

Taking the fightback idea further, into the realms of everyware, Miquel Mora’s IDentity Protection System, shown last month at the RCA’s Great Exhibition (many thanks to Katrin Svabo Bech for the tip-off), aims to offer the individual a way to control how his or her image is recorded – again, Régine from We Make Money Not Art:

With IDPS (IDentity Protection System), interaction designer Miquel Mora is proposing a new way to protect our visual identity from the invasion of ubiquitous surveillance cameras. He had a heap of green stickers that could stick to your jacket. Or anywhere else. The sticker blurred your image on the video screen.

“With the IDPS project I wanted to sparkle [sic.] debate about all the issues related to identity privacy,” explains Miquel. “Make people think about how our society has become a complete surveillance machine. Our identities have already been stored as data in many servers ready to be tracked. And our self image is our last resort. So we really need tools to protect our privacy. We need tools that can allow us to hide or reveal our visual image. We must have the control over it.”

“For example in one scenario a girl is wearing a tooth jewellery with IDPS technology embedded. So when she smiles she reveals it and it triggers the camera to protect her. With IDPS users can always feel comfortable, knowing that with a simple gesture like smiling, they are in control. The IDPS technology could be embedded in all kind of items, from simple badges to clothes or jewellery. For the working prototype I’m using Processing to track the stickers and pixelate the image around when it founds one.”

While the use of stickers or similar tags (why not RFID?) which can be embedded in items such as jewellery is a very neat idea aesthetically, I am not sure what economic/legal incentive would drive CCTV operators or manufacturers to include something such as IDPS in their systems and respect the wishes of users. CCTV operators generally do not want anyone to be able to exclude him or herself from being monitored and recorded, whether that’s by wearing a hoodie or a smart black hat with maroon ribbon. Or indeed a veil of some kind.

Something which actively fought back against unwanted CCTV or other surveillance intrusion, such as reversing the Georgia Tech system in some way (e.g. detecting the CCD of a digital security camera, and sending a laser to blind it temporarily, or perhaps some kind of UV strobe) would perhaps be more likely to ‘succeed’, although I’m not sure how legal it would be. Still, with RCA-quality interaction designers homing in on these kinds of issues, I think we’re going to see some very interesting concepts and solutions in the years ahead…

The right to click

English Heritage, officially the Historic Buildings and Monuments Commission for England, and funded by the taxpayer and by visitors to some of its properties, does a great deal of very good work in widening public appreciation of, and engagement with, history and the country’s heritage.

But its ViewFinder image gallery website* sadly falls into the trap of trying to restrict public engagement rather than make it easy. Yes, someone specified the old ‘right click disabled‘ policy:

English Heritage Viewfinder: right-click disabled
Screenshots of this page, launched from this page.

Now, the image in question – here’s a direct link – which happens to be an engraving of the former Datchet bridge**, in 1840 according to this page (with a colour image) is, even taking English Heritage’s “1860-1922” suggested date range, surely out of copyright, so presumably there cannot be any ‘legal’ question over ‘letting’ people save a copy (which is easiest to do by right-clicking on the most common operating systems and browsers). Using Javascript to remove the browser toolbars and menus also hides the ability to print the image for most users, presumably also deliberately.

Yes, of course, many (most?) readers of this post will know how to get around the no-right-click architecture of control, but you’re reading a technology blog; think of whom the site is presumably aimed at. It is supposed to be a resource to encourage public engagement with history and heritage. Most users will be computer-literate enough to know how to search and probably familiar with right-clicking, but not to mess round with selectively disabling Javascript. Why should they have to? Incidentally, if you do disable Javascript entirely, you can’t even view an enlarged image at all:

English Heritage Viewfinder

What actual use to the public, other than for momentary on-screen interest, is a photo archive website where nothing can be ‘done’ with the images? What is a child doing a local history project supposed to do? Order a print at £18.80 for each photo and then scan it in? Does English Heritage really think that the ability for someone to save or print or e-mail a low-resolution 72 dpi image is going to devalue or compete with the organisation in some way?

It’s ridiculous: such a short-sighted, narrow-mindset policy removes a significant proportion of the usefulness of the site. I don’t know whether the site developer did this with or without English Heritage’s instruction or cognizance (and it was in 2002, so perhaps different thinking would apply today), but it seems that no-one bothered to think through what an actual user might want to get from interacting with the site.

In fact, regardless of the fact that this particular image (as with many others on the site) is in the public domain, even the images which are still under copyright (or “© English Heritage.NMR” as the site puts it, NMR being the National Monuments Record) should, of course, be freely downloadable, printable, and do-whatever-you-want-able. Their acquisition, preservation and cataloguing were paid for by the public, and they should all be available as widely, and easily, as possible. As it is, I would call the website a waste of public money, since it does not appear to offer what most intended users would expect and need.

Still, at least the site’s not one giant bundle of Flash. That would make it marginally more hassle to extract the images.
