Subject:Disasters, driving, disruption, and distributed work.
Security:Public

I went to this morning's panel on real-world HCI hoping to hear about the design of computer systems for helping in disasters. It was more of a grab bag, though.

Here are some tidbits:

In experiments simulating the use of robots to find disaster victims, teams of two operators running a single robot were 9 times more likely to find a
victim than a single operator.

According to analysis of data from the WTC disaster, robots provided information to only the operators. Operators had to send information up the chain; sometimes it took up to 12 hours for information to reach the right authority.

Computer models of participants in group work can help you find interesting things to look for in your experimental data, which might save you from having to run an unfeasibly large number of experiments.

About 85% of people have used mobile phones while driving at some point. At any given moment, about 8% of drivers are using their phones. Monitoring the driver's cognitive state (based on sensing eye gaze and other behaviour) and using that to adjust the trigger threshold for early collision warning systems can help prevent accidents.

When people get distracted using their laptops in meetings, there is about a ten-second threshold that both the speaker and the laptop user can tolerate. Beyond ten seconds of laptop use, the laptop user becomes completely disengaged from the meeting and has difficulty re-engaging.

Subject:How realism and gender affect persuasiveness.
Security:Public

Suppose a group of test subjects all see the same argument presented by six different speakers: a real man and a real woman, a male and female animated virtual human, and a male and female animated animal-like character. They all hear the same audio (as spoken by the real man and real woman) but see different video.

Poll #718037 How realism and gender affect persuasiveness.

Do you think people are more persuaded by real humans or virtual humans?

much more persuaded by virtual humans
2(5.9%)
a bit more persuaded by virtual humans
11(32.4%)
about the same
2(5.9%)
a bit more persuaded by real humans
9(26.5%)
much more persuaded by real humans
10(29.4%)

Do you think people are more persuaded by real humans or virtual non-human characters?

much more persuaded by virtual characters
1(2.8%)
a bit more persuaded by virtual characters
8(22.2%)
about the same
4(11.1%)
a bit more persuaded by real humans
10(27.8%)
much more persuaded by real humans
13(36.1%)

Do you think females are more persuaded by females or males?

much more persuaded by females
4(11.1%)
a bit more persuaded by females
8(22.2%)
about the same
4(11.1%)
a bit more persuaded by males
12(33.3%)

8(22.2%)

Do you think males are more persuaded by females or males?

much more persuaded by females
2(5.6%)
a bit more persuaded by females
9(25.0%)
about the same
4(11.1%)
a bit more persuaded by males
9(25.0%)
much more persuaded by males

I'm in a talk presented by Catherine Zanbaka about a study of how realism and gender affected persuasiveness.

Check out the results of their experiment behind this cut, after you've filled in the poll.Collapse )

Subject:Progress bars.
Security:Public

I just saw another talk today with a progress bar in it. This one had a bright green block on a thin track just below the main heading, starting at the left on the first slide and arriving at the right on the last slide.

I used to try to put progress bars in my presentations. These days i often don't feel like i have the time and patience to do it, but it's nice to see more and more talks that seem to be doing it these days. I really ought to get comfortable with Slithy to create things like this programmatically. Slithy is awesome.

Scott McCloud is going to be our closing plenary speaker!! I can't wait.
