Fear over-rides usability in security interfacesSymantec, quoting a June 2005 Gartner and Cyber Security Industry Alliance survey, say that “53 percent of consumers fear identity theft and 14 percent fear online banking; as a result, 30 percent have reduced their Internet use and 42 percent have modified their online shopping behaviour.” Just like selling insurance, vendors of security-related products can rely on fear to do some of their selling. Our fears of identity theft, of online fraud or a financial catastrophe, or losing all our hard-earned data, motivate us to buy security products for our computers. You would think that, once you’ve purchased a product, it would communicate comfort and reassurance – “we’re here now, everything’s going to be OK”. But no, the customer experience frequently continues to be one based on fear. And sometimes, these emotional overtones of the experience over-ride even the most fundamental principles of good interaction design – firstly, understand your users, their goals and tasks; secondly, provide well-designed interaction to help them carry out their tasks and achieve those goals. Let’s look at an example. When Norton And then – in a friendlier font – it says “Norton Internet Worm Detection has detected and blocked an intrusion attempt”. Well, that’s good news, isn’t it? Why couldn’t the headlines have been about good news instead of fear? Maybe “Worm attack prevented!” Maybe the big red circle with a cross on it should be a big green shield with a tick? Well, whatever, at least we now know it’s good news. Or do we? Because it is a "Security Alert”, and it does say “High Risk”. This suggests that I am still at risk of something. What is the high risk? What can I do about it? What am I supposed to do now? Aren’t these the obvious questions consumers will have at this point? So what can I do next? What are the affordances that might get me answers to my questions, provide closure to this interaction, and help me attain my goal of feeling secure (which is why I bought this product in the first place)? There are a few opportunities for action that this alert offers me: 1. I can click “OK” or close the window 2. I can click on “more info” 3. I can check a box that says “Don’t show an alert for this threat again 4. I can “hide details” 5. I can read a lot of text unhelpfully provided in a small scrolling window that lets me view 4 lines at a time There are many other problems with this dialogue and with other security-related user interfaces, not just those of Symantec. This example illustrates the - to us obvious - user needs that should have been supported in this one simple dialogue, so that users could get questions answered and feel a deep sense of reassurance. The customer experience issues could quickly have been identified with a simple heuristic evaluation, or a one-day usability test with a handful of users. Do neither of these things happen in Symantec? Does the company somehow prioritize usability below the need to perpetuate fear? We believe that products reflect the culture and organization of the companies that produce them. If your company thrives on fear, that will show in its products. If it thrives on understanding its customers, that will also show. We would say that the culture of fear is so deeply embedded in many security companies that it pervades their organizational structure, their software development processes, and the way managers make decisions and prioritize design - at the expense of their customer experience. On a related note, if you are thinking of installing Norton 360 or a similar security product in the next few weeks, and could record your own user experience for us (with some guidance), get in touch with us. Let’s go to Latin Square (About stupid ‘smart’ things, Artificial Intelligence, and the semantic web)
No Latin Square tool. But wait a minute; it thinks it’s an address. Cool – I guess there could really be a place called ‘Latin Square’. So could I add this address to my contacts, or see a map? Well, first let’s take a look at the driving instructions…. Oh. OK, so not only does it not really know any Latin Square, Typical of many so-called ‘smart’ things, these tags are just plain stupid. And they tell lies about what they know, until you call their bluff. Are they embarrassed when they are found out? No, like some drunken fool at a party they continue to pop up, stupid as ever. I have to tell them to stop. Any normal ‘smart’ creature would keep quiet after having been exposed this way. Calling things ‘smart’ or ‘intelligent’ and building them stupid was (and probably still is) an occupational hazard in Artificial Intelligence (AI) research and development. A team I worked with in AI came up with the principle – “If at all possible, avoid intelligence”. So what’s this got to do with the semantic web? There are two ways most people build smart things. The first is to emulate human intelligence. And as soon as you say ‘smart’ or ‘intelligent’, that’s the route researchers often take. This usually results in ‘stupid’ things. The other way is to really constrain what you do, and to build it on a flexible and powerful supporting infrastructure. For example, Google's search engine simply relies on processing huge amounts of text, encoded in simple structures with HTML, from an enormous number of web pages. Many people are already confusing the semantic web with something to do with ‘intelligence’ – after all, it’s about semantics, about meaning, so that must mean intelligence, right? Wrong. It’s about encoding semantics – and not in a big AI way – into data so that computers can share more data. This is why Amazon’s Jeff Bezos says that the semantic web is "about making the Internet useful for computers." In Tim O'Reilly's review of Danny Hillis's Metaweb venture, he points out that: “…the really powerful thing about this is that all these categories, these data types and the web of fields that define them, provide new hooks for applications that will be able to extract meaning from the data.” If you want to see another amazing example of the power of hooking together masses of data in simple ways - in this case people's photos on Flickr, take a look at Blaise Aguera y Arcas's demo of Photosynth from the recent TED conference. The semantic web is about encoding what data are about and what they relate to, so that we can follow the scent of whatever information interests us, take a look at information from our perspective and put information together in new ways that might interest other people. And while we’re doing that, we’ll be cruising and accessing hundreds – and more – of globally-connected, always-on databases without even realising it. Most of our current applications are crude, dull and stupid, because they try to be ‘smart’ but understand nothing. The semantic web simply aims to connect together lots of small pieces of meaning, to create the infrastructure where ‘smart’ turns into something useful and enabling.

Anti-Virus (this example is from the 2006 version) detects a Worm, the user can be informed. A window pops up. “Security Alert” it says, and “High Risk”. There’s a big red circle with a big cross in it. They might as well set off sirens and shout “Don’t Panic”! 
While writing up a usability test plan, describing how we would use a Latin Square technique to counter task order effects, I noticed the ‘Smart Tag’ pop up by “Latin Square”. Well, despite all my previous encounters with smart tags, I was intrigued.
smart tags really do know something about Latin Squares. Maybe it will offer me a Latin Square generator…” So I clicked on the little arrow. Sigh.
but it doesn’t even have ‘Latin Square’ entered as text in the address field (although it assumes most places I’m interested in are in New York)! 
We'd love to hear your comments on stupid 'smart' things or the semantic web
