Alright, it's maybe not the worst situation in the world, but we just got back from two weeks in Hawaii on holiday and I experienced a distressing situation on the five hour flight back from the Big Island to San Francisco (where we overnighted): an abusive parent and her child in my row of the plane.

As is common with airlines, we booked months in advance but couldn't get our five seats together, so we had three seats in one row, one seat immediately ahead of it, and one seat two rows ahead of that. Not so good when we're traveling with the kids, needless to say, but since K-'s now two, we have to buy her a seat too.

We decided that we'd arrange it so that Linda and all three kids were squished into the three-seat row (with the baby on her lap to hopefully sleep) and I'd be in the row immediately ahead.

But when we were all trying to settle into our seats, I was joined by a heavyset native Hawaiian woman and her five year old (I'm guessing) daughter. Her daughter promptly stood on the chair to look over and meet our kids and the Mom...

I'm in the 'alt.chi' session, which is a collection of papers that are very interesting projects but for one reason or another would not compete well against traditional research papers to make it into the conference programs.

First project: incorporating digital technologies into a playground.  Their first prototype was a mat (looks sort of like two sets of train tracks, side by side) that kids could step or run on, and hitting pressure mats would activate motors. In their second iteration, they got the kids involved in making spinners to put on the motors. Then they observed how kids used it and experimented with it, including inventing their own games.  Their big goal: use technologies toaugment playground equipment without compromising the nature of unstructired play?

Second project: Tokyo Youth at Leisure, supporting the design of new meida to support leisure planning and practice. A user study of young adults aged 18-25 (the only age group that actually has free time) to see how they plan and participate in their leisure outings. Relaxation and companionship were the most important leisure qualities; finding new romance was the least. People and TV were the top resources for planning outings, mobile device was very low (though distinguish planning from coordination, where mobile and PC are used extensively).  'downtime' is essential; they often spend it alone, but hyper-connected (via email and mobile phone). For group outings, you choose the set of people you want to be with first, then decide what to do. Planning a meeting place for a specific activity is the process of minimizing the commute and maximizing opportuinities for other serendipitous activities. One interesting take-away: lots of cultural hype of mobile phones' hyperuse as distinctly Japanese, but the PC was used a lot more than was expected; people liked the large screen for viewing information and planning activities.

Third project: RoomBugs. simulating insect infestations in elementary school classrooms.  Kids use computers to run a simulation over several days of insects in the classroom, as a science experiment where they need to quantify can classify the infestation. PC's act as stations around the room and show the virtual equivalent of a 'sand trap' where they see insect tracks as virtual insects walk voer them. Kids were able to correctly count and identify 94% of over 1500 insect tracks that they were exposed to over a 2-week period. Yow!

Fourth project: Orbital Browser. How to connect up components in a ubiquitous computing environment.

Fifth project: Quill: a narrative-based interface for personal document retrieval.
