What do the Wii and the iPhone have in common, besides being two of the hottest gadgets of the year? You can communicate with each of them via gesture. We will probably see more such devices, and so there is a need for standardization of gestures.
Not owning either of the above-mentioned devices, I didn’t realize the need for standardization until Read/Write Richard posted about it. I don’t think I’ll listen to the podcast he recommends; podcasting about gestural interaction seems like one of those “dancing about architecture” things.
I did follow the link to Dan Saffer’s call to arms (or, I guess, fingers), and read it with interest. Perhaps gestures for “spread to enlarge” and “pinch to shrink” will become as familiar as cutting and pasting.
