Right Round Round Round

Enjoy unsolved mysteries?

Here's one for you: why do people travel in circles when they can't see a fixed landmark?




Apparently, difference in limb lengths doesn't explain this behaviour (eg. driving the car) so this remains an unsolved question.

I wonder if you'll see the same circling movement if you make the blindfolded person lie down on a skateboard, so as to position the inner ear balance organs 90 degrees to the usual orientation.

Or if there is still circling if you give the subject a fixed auditory landmark, like a tall loudspeaker.

Beware Of Geeks Bearing Fembots

Latest development by Hiroshi Ishiguro's group: the Actroid-F.

Now attempting to bridge the uncanny valley with fast facial expressions!



The multiple eye blink demonstration from 1:26 - 1:33 is very impressive. To me, one major reason why androids today look so stiff is due to the sluggishness of the actuators.

People don't slowly move their heads and facial muscles into position; they sort of "snap" into it.

In that respect, the current Actroid-F appears to have the fastest motor response of any android so far. Older videos of the Actroid-F in April still show the slow eye blink and head movement, so something must have been enhanced since then, be it faster motors and/or software.

Also, I think there is one point in this video where the Actroid briefly slips across the uncanny valley.

It's at 1:46, when after repeating a series of mechanical-looking mouth movements, the Actroid suddenly shifts attention to the left in a snappy, human sort of way.

In that instant, the robot seemed to be alive.

Looking at the progress so far, this is merely a little taste of what is to come.

Pick Your Brain For Some Loose Change... And Your Watch

Here's an intriguing Scientific American video that uses street magic to help illustrate some concepts in neuroscience.

Or is it using neuroscience to help illustrate some concepts in street magic?



Not surprisingly the street magician steals the show, after all, it's his job to capture your attention by being in your face, enthusiastic and funny.

Whereas the scientists appear standoffish and matter-of-fact.

This distinct contrast tells us that there's some showmanship going on here, and obviously it's the magician who's doing it.

Next Up, World Domination. But First, Here's A Song For You!

You know them pop stars - celebrities who don't play instruments, can't sing and can't really dance either.

Behold the next step in prepackaged, manufactured entertainment...



Whoa, that's almost... adorable.

As YouTubber anharmyenone grimly observed: "Skynet is a Japanese idol singer."

Verily I say, beware of Those with the half-bent knees and awkward head-shake.

Heh.

Update 24 Dec 2010: Video with clearer (less buzzy) sound quality and some close-ups of the robot - from AIST Channel.

Later!

Wow, it's been months since my last post! Currently I don't have the need to blog any more, and I'm often travelling regionally, so unlikely to have regular updates.

For the long time readers of Fresh Brainz, many thanks for your support in the past four years! Cheers and so long!
