For Your Consideration: Tapworthy iPad Apps at SXSW
So I'd like to speak at SXSW again, and I need your help.
Specifically, I need just two minutes of your time to vote for my talk. If you're not already familiar with SXSW Interactive, it's a fabulous brain-bending shindig in Austin, TX, about technology, media, and culture. I was incredibly flattered by how well my SXSW talk about tapworthy iPhone apps was received this year. For next year, I hope to give the tapworthy treatment to the iPad, with a talk on the many design considerations and...

The Twitter Uncertainty Principle: How Tweeting Changes Us
I Tweet Therefore I Am is a lovely and thoughtful essay by Peggy Orenstein about the effects Twitter has on the way she experiences the moments of her day:
On a recent lazy Saturday morning, my daughter and I lolled on a blanket in our front yard, snacking on apricots, listening to a download of E. B. White reading "The Trumpet of the Swan." Her legs sprawled across mine; the grass tickled our ankles. It was the quintessential summer moment, and a year ago, I would have been fully...

How Big Is Big Enough?
The crew at O'Reilly Answers recently posted an excerpt from Tapworthy about the ideal size of iPhone tap targets. Forty-four is the magic number:
Just how big is big enough when it comes to iPhone tap targets? Well, what's the size of a fingertip? Apple pegs it precisely at 44 pixels and this measure appears reliably throughout the standard iPhone controls. In portrait orientation, 44 pixels is the height of buttons in the Calculator app, of the keys of the iPhone's virtual keyboard...

Develop iPhone Apps with Staying Power
This week at Mashable, I shared some ideas for extending the (alarmingly brief) lifespan of mobile apps. Here's the dilemma app developers face:
An app's shelf life lasts exactly as long as it can hold users' attention. iPhone owners chew through apps, gulping down their content, then tossing them out and moving on. that the average user never launches an app more than 20 times before abandoning it. of downloaded apps get so much as a glance over the...

Providence UX Meetup: July 20
Hey Providence peeps, on Tuesday July 20, grab a wireframe, a color palette, and a cocktail glass to mix it up with local user-experience pros. A few folks are staging a casual meetup of designers and UX nerds. If you dig liquids, interaction design, info architecture, and usability, come join us!
This is the second outing for this fandango; a few interaction designers kinda spontaneously got together for a social meetup a few weeks ago, and we...

Designing for iPhone 4's Retina Display
So, um, maybe you heard: there's a new iPhone out. For my money (and I shelled out plenty for it), the phone's best feature is the new "Retina display," the eye-popping high-resolution screen. Everything they say about it is true: at 320 ppi, the pixels are just plain invisible. The crisp bright screen really looks as good as print, absolutely gorgeous.
But what soothes the eye also adds headaches for designers. For three years, the iPhone came in just one flavor of screen resolution: the...

Graffiti Compasses, Welcome Mats, and the Art of the Generous Greeting
Love this. Seems an anonymous do-gooder is making some guerrilla usability improvements to the New York subway, spray-painting compass points outside stations to help emerging passengers get their bearings. NYC the Blog has the details along with photos.
NYC theIt's a simple solution to a common problem, how to ease the blinking confusion of disoriented straphangers arriving at a new station. Web and software designers oughtta have the same...

Dieter Rams and the Fresh Prince
I was chuckling over this Fresh Prince photo at Design Dare the other day. "Now they all look dumb," wrote Design Dare's Jon Bell of Will Smith's fresh eighties entourage. "Oh, fashion."
Got me thinking about the difficulty of truly timeless design, whether for fashion or objects or software interfaces. Designers and their creations are captive to their times, and notions of "good design" constantly shift under our feet. I tweeted that...
