Human-Computer Interface: The Simplicity of Asking and Telling

Simplicity in user interface combined with the power of the what is returned equals uncommon success.

Google User Interface

The Google interface allows complex queries with the most basic interaction.

 

Twitter User Interface

The Twitter interface allows publication into the social conversation stream with a user interaction that looks very similar.

One interaction is asking, the other is telling.

The Precise Ambiguity of @megfowler ‘s definition of Twitter

Ludwig Wittgenstein

Meg Fowler threw up her hands and finally said, “This is what I do.” She was trying to explain how Twitter goes to some new users. It’s a question that surfaces naturally with the uninitiated. They examine the “rules” and the capabilities, and then answer the question “What are you doing?” But somehow that doesn’t seem to adequately represent the buzz of talk surrounding Twitter.

The first thing new users observe, once they start following veteran users is that the question about what one is doing is only occasionally answered. What are the rules they ask, what are the rules about what to put in to those 140 characters, if you’re not answering the question?

This is where words begin to fail us. How to explain all that is not answering a question? How to explain who hears and who doesn’t? How to explain the river of talk that one follows? To explain one’s experience of Twitter, is to explain one’s self. Everyone’s experience is slightly different.

Meg Fowler’s description brought to mind Ludwig Wittgenstein’s discussion of how we learn and use language in his book Philosophical Investigations. Certainly we can talk about rules when we speak of language. But that’s not how we learn and eventually use language. Rather than learning a set of rules, it’s more a case of “this is what I do,” and you must do what you do.

Asking what one should fill the 140 characters with is like asking what words one should fill one’s voice with. Many social network sites attempt to provide context and set the rules of engagement. Following rules is what machines do, not what people do. I’ve often thought of human-computer interaction as the encounter between a world purged of ambiguity with a world filled with ambiguity. Twitter thrives on the ambiguity of its purpose, it’s a machine that leaves room for the human.

And Meg Fowler, why look to her as an authoritative voice? In a medium where most of use are finding our way and learning the landscape, Ms. Fowler has filled in those 140 characters more than 11,646 times.

The 2-Way Web by Starting Small: 6 Word Bios, Twitter & @newsgang

Bertolt Brecht

I’d seen it before, but I was reminded again today driving and listening to the radio. It was a show about the 6 word biographies collected by the folks over at Smith Magazine. The 6 word biography is based on a six word novel by Hemingway:

For sale, baby shoes, never used

The interesting thing about the limitation of six words is its liberating effect. Professional writers become addicted, and “everyday writers” are enabled to create great work. This brings to mind the two-way web and the ability of users to write, take photographs, make music, make movies, create complex hypertext documents. But what users have really embraced are things like the structured life narrations via social or interest groups, and short creative forms like Twitter.

With Twitter it’s the simplicity combined with the constraints that produces the outpouring of writing. It’s biography in 140 characters; it’s a novel in 140 characters; it’s a dialog among citizens of a democracy in 140 characters; it’s the conversation about what’s going on right now in 140 characters. Twitter is one of the most successful forms of the two-way web because it stays out of the way and lets the voices come through.

Sometimes it takes a long time for an idea to reach fruition. The names that come to mind are Vannevar Bush (As We May Think), Ted Nelson (Hypertext), and Doug Englebart (GUI HCI), among others. One that you might not think of is Bertolt Brecht. After listening to the Friday, March 14th NewsGang and Gang podcasts, I think Brecht would be smiling. Here’s something that he wrote in 1932:

…radio is one-sided when it should be two It is purely an apparatus for distribution, for mere sharing out. So here is a positive suggestion: change this apparatus over from distribution to communication. The radio would be the finest possible communication apparatus in public life, a vast network of pipes. That is to say, it would be if it knew how to receive as well as to transmit, how to let the listener speak as well as hear, how to bring him into a relationship instead of isolating him. On this principle the radio should step out of the supply business and organize its listeners as suppliers. Any attempt by the radio to give a truly public character to public occasions is a step in the right direction.

Radio has begun genuinely moving in two directions. We live in interesting times, and according to Brecht, we seem to be moving in the right direction.

The Things We Use The Most Have The Worst User Interfaces

One by one, Apple is taking on the lousy interfaces we have to deal with every day. The mobile telephone has had a terrible interface forever. When you’re selling the subscription to the pipe, the device is meaningless. The iPhone isn’t really a phone, and that’s the revolution in the device.

Cable television listings are impossible to search and the remote control is ill suited to the task. The economics are the same. The cable business isn’t about the user interface, it’s all about selling cable subscriptions. As long as it’s not an active negative, the method of finding, selecting and recording televisions will never improve.

There’s a revolution hidden in fixing television’s interface, because the new schema will include both hundreds of television channels, on-demand shows, music channels, and all the multiple media channels of the internet. We’ve become so used to working with terrible interfaces that we don’t even understand that something better is possible.

As with the iPhone, software will be the key. Cable television’s interface cannot iterate except in extreme circumstances. The software model is key to moving the interaction forward, and Apple seems to be the only company positioned to the HCI experiments at the edge into the mainstream.
