I first taught human-computer interaction (HCI) in 2001. I taught it from a viewpoint of software engineering. Then, when I taught it again, I taught it from a design point of view, which was a bit trickier, as I didn’t want to trawl through a load of general design principles which didn’t absolutely boil down to a practical set of guidelines for graphical-user interface or web design. That said, I wrote a whole generic set of design principles here: Designing Design, borrowing Herb Simon’s great title: The Science of the Artificial. Then, I revised my HCI course again and taught it from a practical set of tasks so that my students went away with a specific skill set. I blogged about it in a revised applied-just-to-web-design version blog series here: Web Design: The Science of Communication.

Last year, I attended a HCI open day Bootstrap UX. The day in itself was great and I enjoyed hearing some new research ideas until we got to one of the speakers who gave a presentation on web design, I think he did, it’s hard to say really, as all his examples came from architecture.

I have blogged about this unsatisfactory approach before. By all means use any metaphor you like, but if you cannot relate it back to practicalities then ultimately all you are giving us is a pretty talk or a bad interview question.

You have to put concise constraints around a given design problem and relate it back to the job that people do and which they have come to learn about. Waffling on about Bucky Fuller (his words – not mine) with some random quotes on nice pictures are not teaching us anything. We have a billion memes online to choose from. All you are doing is giving HCI a bad name and making it sound like marketing. Indeed, cyberpsychologist Mary Aiken, in her book The Cyber Effect, seems to think that HCI is just insidious marketing. Anyone might have been forgiven for making the same mistake listening to the web designer’s empty talk on ersatz architecture.

Cyberpsychology is a growing and interesting field but if it is populated by people like Aiken who don’t understand what HCI is, nor how artificial intelligence (AI) works then it is no surprise that The Cyber Effect reads like the Daily Mail (I will blog about the book in more detail at a later date, as there’s some useful stuff in there but too many errors). Aiken quotes Sherry Turkle’s book Alone Together, which I have blogged about here, and it makes me a little bit dubious about cyberpsychology, I am waiting for the book written by the neuroscientist with lots of brainscan pictures to tell me exactly how our brains are being changed by the Internet.

Cyberpsychology is the study of the psychological ramifications of cyborgs, AI, and virtual reality, and I was like wow, this is great, and rushed straight down to the library to get the books on it to see what was new and what I might not know. However, I was disappointed because if the people who are leading the research anthropomorphise computers and theorise about metaphors about the Internet instead of the Internet itself, then it seems that the end result will be skewed.

We are all cyberpsychologists and social psychologists, now baby. It’s what we do. We make up stories to explain how the world works. It doesn’t mean to say that the stories are accurate. We need hard facts not Daily Mail hysteria (Aiken was very proud to say she made it onto the front page of the Daily Mail with some of her comments). However, the research I have read about our behaviour online says it’s too early to say. It’s just too early to say how we are being affected and as someone who has been online since 1995 I only feel enhanced by the connections the WWW has to offer me. Don’t get me wrong, it hasn’t been all marvellous, it’s been like the rest of life, some fabulous connections, some not so.

I used to lecture psychology students alongside the software engineering students when I taught HCI in 2004 at Westminster University, and they were excited when I covered cognitive science as it was familiar to them, and actually all the cognitive science tricks make it easy to involve everyone in the lectures, and make the lectures fun, but when I made them sit in front of a computer, design and code up software as part of their assessment, they didn’t want to do it. They didn’t see the point.

This is the point: If you do not know how something works how can you possibly talk about it without resorting to confabulation and metaphor? How do you know what is and what is not possible? I may be able to drive a car but I am not a mechanic, nor would I give advice to anyone about their car nor write a book on how a car works, and if I did, I would not just think about a car as a black box, I would have to put my head under the bonnet, otherwise I would sound like I didn’t know what I was talking about. At least, I drive a car, and use a car, that is something.

[pullquote]Hey! We’re not all doctors, baby.[/pullquote]

If you don’t use social media, and you just study people using it, what is that then? Theory and practice are two different things, I am not saying that theory is not important, it is, but you need to support your theory, you need some experience to evaluate the theory. Practice is where it’s at. No one has ever said: Theory makes perfect. Yep, I’ve never seen that on a meme. You get a different perspective, like Jack Nicholson to his doctor Keanu Reeves says in Something’s Gotta Give: Hey! We’re not all doctors, baby. Reeves has seen things Nicholson hasn’t and Nicholson is savvy enough to know it.

So, if you don’t know the theory and you don’t engage in the practice, and you haven’t any empirical data yourself, you are giving us conjecture, fiction, a story. Reading the Wikipedia page on cyberpsychology, I see that it is full of suggested theories like the one about how Facebook causes depression. There are no constraints around the research. Were these people depressed before going on Facebook? I need more rigour. Aiken’s book is the same, which is weird since she has a lot of references, they just don’t add up to a whole theory. I have blogged before about how I was fascinated that some sociologists perceived software as masculine.

In the same series I blogged about women as objects online with the main point being, that social media reflects our society and we have a chance with technology to impact society in good ways. Aiken takes the opposite tack and says that technology encourages and propagates deviant sexual practices (her words) – some I hadn’t heard of, but for me, begs the question: If I don’t know about a specific sexual practice, deviant or otherwise, until I learn about on the Internet (Aiken’s theory), then how do I know which words to google? It is all a bit chicken and egg and doesn’t make sense. Nor does Aiken’s advice to parents which is: Do not let your girls become objects online. Women and girls have been objectified for centuries, technology does not do anything by itself, it supports people doing stuff they already do. And, like the HCI person I am, I have designed and developed technology to support people doing stuff they already do. I may sometimes inadvertently change the way people do a task when supported by technology for good or for bad, but to claim that technology is causing people to do things they do not want to do is myth making and fear mongering at its best.

The definition of HCI that I used to use in lectures at the very beginning of any course was:

HCI is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them (ACM, 1992).

For me, human-computer interaction was and still remains Gestaltian: The whole is greater than the sum of the parts, by this I mean, that the collaboration of a human and a computer is more than a human typing numbers into a computer and then waiting for the solution, or indeed typing in sexually deviant search terms into a web crawler to find a tutorial. And, with the advent of social media, HCI is more than one person connecting to another, or broadcasting online, which is why the field of cyberpsychology is so intriguing.

But the very reason why I left the field of AI and went into HCI is: AI reasons in a closed world and the limits of the computational power you have available. There are limits. With HCI, that world opens up and the human gets to direct the computer to do something useful. Human to human communication supported by technology does something else altogether which is why you might want the opinion of a sociologist or a psychologist. But, you don’t want the opinion of the sociologist on AI when they don’t understand how it works and has watched a lot of sci-fi and thinks that robots are taking over the world. Robots can do many things but it takes a lot of lines of code. And, you don’t want the opinion of a cyberpsychologist who thinks that technology teaches people deviant sexual practices and encourages us all to literally pleasure ourselves to death (Aiken’s words – see what I mean about the Daily Mail?) ‘cos she read one dodgy story and linked it to a study of rats in the 1950s.

Nowadays, everyone might consider themselves to be a bit of a HCI expert and can judge the original focus of HCI which is the concept of usability: easy to learn, easy to use. Apps are a great example of this, because they are easy to learn and easy to use, mainly though because they have limited functionality, that is they focus on one small task, like getting a date, ordering a taxi, sharing a photo, or a few words.

However, as HCI professor Alan Dix says in his reflective Thirty years of HCI and also here about the future: HCI is a vast and multifaceted community, bound by the evolving concept of usability, and the integrating commitment to value human activity and experience as the primary driver in technology.

He adds that sometimes the community can get lost and says that Apple’s good usability has been sacrificed for aesthetics and users are not supported as well as they should be. Online we can look at platforms like Facebook and Twitter and see that they do not look after their users as well as they could (I have blogged about that here). But again it is not technology, it is people who have let the users down. Somewhere along the line someone made a trade-off: economics over innovation, speed over safety, or aesthetics over usability.

HCI experts are agents of change. We are hopefully designing technology to enhance human activity and experience, which is why the field of HCI keeps getting bigger and bigger and has no apparent core discipline.

It has a culture of designer-maker which is why at any given HCI conference you might see designers, hackers, techies and artists gathering together to make things. HCI has to exist between academic rigour and exciting new tech, no wonder it seems to not be easy to define. But as we create new things, we change society and have to keep debating areas such as intimacy, privacy, ownership, visibility as well as what seems pretty basic like how to keep things usable. Dix even talks about having human–data interaction, as we put more and more things online, we need to make sense of the data being generated and interact with it. There is new research being funded into trust (which I blogged about here). And Dix suggest that we could look into designing for solitude and supporting users to not respond immediately to every text, tweet, digital flag. As an aside, I have switched off all notifications, my husband just ignores his, and it just boggles my mind a bit that people can’t bring themselves to be in charge of the technology they own. Back to the car analogy, they wouldn’t have the car telling them where they should be going.

Psychology is well represented in HCI, AI is well represented in HCI too. Hopefully we can subsume cyberpsychology too, so that the next time I pick up a book on the topic, it actually makes sense, and the writer knows what goes on under the bonnet.

Technology should be serving us, not scaring us, so if writers could stop behaving like 1950s preachers who think society is going to the dogs because they view how people embrace technology in the same way they once did rocknroll and the television, we could be more objective about how we want our technological progress to unfold.
