Last night to a standing room only IxDA NY audience at R/GA for Dan Saffer presented what I’m going to guess is an outline of his new book Interactive Gestures: Designing Gestural Interfaces (you can download the first chapter at the site) that is coming out soon.
At the end of his talk he mentioned that he would be putting up his slides which I’ll link to once I see them on the Kick It site. You can download the Tap is the New Click Presentation HERE. He likened the next couple of years of gestural interface experimentation to the early years of the web – both the good and bad. As a primer on this emerging field I though the talk was pretty good. I’m hesitant to do a play by play of points b/c that’s what his book and slides can do clearly. But what I want to do is point out a couple things that I found interesting from the pov of someone using an iphone, kiosks and the clapper.
There’s two types of touch screens – iceberg tips which have a small target yet there’s a larger surface surrounding that target that is live. The other is adaptive targets which is kind of like the keyboard on an iphone. As you type in letters the sensors guess what is more likely to be the next letter and create a bigger target b/c of it. On communicating interactive gestures there’s three points to consider: 1. attraction, 2. observation and 3. interaction. If you have an iPhone you know about the unlock slide to turn it on. That type of interaction is known as attraction affordance. It introduces the person to a type of gesture that the interface uses. As for a philosophy to consider, the simpler the task should equate to the simpler the gesture. The best designs dissolve into behaviour.
The q & a afterwards was surprisingly good – my experience in the past at talks in general has not been the case. Some topics covered included tech. will be abused as necessary, sensors as a green issue in bathrooms, face recognition for ads, gesture pollution, will a room be an apple or microsoft room – the implications of that, brainwaves are not gestures, will gesture be patentable or gestures plus a response system be patentable and wearable technology.
