Just a few short updates:

  • We now have a full 25 cameras in the front half of the Visitor’s Center, which gives us pretty great coverage of these areas. Both wide establishment shots and close-up interaction angles cover the touch tanks, wave tanks (still not quite fully open to the public) and a few freshwater creatures tanks that are more traditional tanks where visitors simply observe the animals.
  • Laura got a spiffy new EcoSmart pen that syncs audio with written notes taken on special (now printable from your printer) paper. She showed us how it translates into several languages, lets you play a piano after you’ve drawn the right pattern on the paper, and displays what you’ve written on its digital screen, performing pretty slick handwriting analysis in the process.
  • Katie ran the lab’s first two eyetracking experimental subjects yesterday, one expert and one novice pilot (not quite from the exact study population, but approximately). Not only did the system work (whew!), we’ve even got some interesting qualitative patterns that are different between the two. This is very promising, though of course we’ll have to dig into the quantitative statistics and determine what, if any, differences in dwell times are significant.

Sometimes, it’s a lot of small steps, but altogether they make forward progress!

 

 

The pace of research often strikes me as wonky. This, I suppose, is true of a lot of fields: some days, you make a lot of progress, and some days very little. A series of very small steps eventually (you hope) lead to a conclusion worthy of sharing with your peers and advancing the field. That means a lot of days of working in the trees without being able to see the forest.

Conferences, with their presentation application deadlines, have a funny way of driving research. I applied for the International Conference on Science Communication back in March and outlined all this data I figured I’d have for my thesis by the time the conference rolls around in the first week of September. Amazingly, I’m on track to have a fairly good amount of data, despite delays due to subject recruitment and IRB approval that I’ve talked about before.

However, now I have another twist in the process. Usually, one can work on the conference presentation almost up until the very moment of the presentation, especially if you get to host the presentation slides on your own laptop. This conference, though, requires me to have my final presentation almost 7 weeks before the actual presentation date. I can only assume this is because the conference, to be held in Nancy, France, is going to be held concurrently in both French and English, and thus, the organizers need this time to be able to translate my slides into French (of which I speak not a word).

In any case, this throws a major wrench into my planned schedule! I am doing fine with the pace, and have about half of my needed faculty interviews arranged (with 25% actually completed!). This deadline this week throws me into a strange dilemma of how to present something interesting, especially the visual data from eyetracking experiments, without actually being able to show them at the conference, as far as I can tell. I figure I will have some results from my actual subjects by the time of the conference, but I don’t know which subjects I will want to choose for that part until all of the interviews have been completed. So my solution will be to run a couple of pilot subjects on just the eyetracking part, without the interview. I’ve recruited one of the folks that works closely with us to be more of an “expert” user, and a member of the science and math teacher licensure master’s program to serve as a “novice.” I’m really excited by what the interviews have revealed so far and am hopeful that the eyetracking pilots will go as well. Crossing my fingers that this will be interesting to the conference attendees, too, with whatever verbal updates I can provide to accompany my slides in September.

Mark located an ultra-cheap compact USB video camera and microphone online. By ultra-cheap, I mean $10. Laura clipped it to her shirt and gave it a quick trial run in the Visitor Center.

It had remarkably good resolution, but muffled audio quality beyond about two feet. Also, we found that a lapel-mounted camera moves a lot, making it hard to discern what the wearer is attending to.  This new gadget may have some use if affixed to an exhibit, but it doesn’t compete with the Looxcie as a visitor-mounted camera.

My favorite aspect of the product, however, is the instruction manual.  This document stands as a heroic failed attempt to translate coherent thoughts into the awkward and confusing linguistic soup we call “English.”

Here are some highlights:
-When you charge it, blue light and red light will bright simultaneously, of which states are stillness.
-Notice: when battery power is not enough, D001 will enter into protection mode, so it cannot be turn on.  Now, please charge for it.
-If you need to continue to video, please press Record/Stop button slightly once more.

Our other projects are moving along quickly.  The wave tanks should arrive next week.  The data collection cameras should in within two weeks.  If you haven’t seen Katie’s test run of the SMI eye-tracking system, you can watch a quick video of it here.

Our actual eyetracker is a bit backordered, so we’ve got a rental for the moment. It’s astoundingly unassuming looking, just (as they picture on their web site) basically a small black bar at the bottom of a 22” monitor, plus the laptop to run the programs. When I took it out of the box, it fires up the operating system and there are the icons just sitting on the desktop, with a little warning that we shouldn’t mess with any settings, install a firewall or anti-virus software for risk of messing up the primary function. They have branded the screen with a little decal from their company, but otherwise, it’s just a laptop with an attached monitor.

 

The actual getting started is a bit complicated.  I’m usually the one to pooh-pooh the need for “readme” documents, but I would have liked one here to tell me which program is which. That’s the thing – the software is powerful, but it has a bit of a steep learning curve. The “quick start” guide has several steps before you even think about calibrating a subject. We got stuck on the requirement to get Ethernet hooked up since we tried to set up in a tech closet and OSU otherwise has pretty widespread wireless coverage. Harrison had to run a 50’ cable from Mark’s office down the hallway to the closet.

 

Looks like the next step is some pretty intense work understanding how to set up an experiment in a different software program. This is where a “test” experiment just to start learning how to use the system would be good. That’s the sort of icon I need in the middle of the desktop. It reminds me of my first job as a research assistant, where I was registering brain images to a standard. The researchers had written a program to rotate the images to line up and then match certain features to the standard to stretch or compact the images as necessary, but there was no manual or quick start. My supervisor had to show me all the steps, what button did what, which order, etc. It was a fairly routine process, but it was all kept in someone’s head until I wrote it down. The pdfs here are a great start, but there still seems to be a step missing. Stay tuned!

 

Have we made the right decision? I am still getting queries from companies that I contacted over the course of the process. One company’s main guy contacted me after weeks of no contact. I told him that the guy he’d referred me to had ignored my request to set an appointment to talk to him. The main guy tried to tell me he had referred me to a different person than I told him! Some of these businesses seem very strange and disorganized. We definitely based some of our decisions on how strong the companies seemed, especially based on their web presence and their general conduct.

In any case, another wrinkle may be in store for us. We heard from Anthony Hornof at the University of Oregon that the Oregon University System (of which both our schools are a part) required him to basically decide on the specifications for a system and “put it up on the web for bid” for a month, even though he had already chosen the system and the vendor that best suited his project. Luckily, no one responded to the public bid and he was able to go with what he wanted. Maybe the fact that we’re specifying the system in our matching funds proposal will help us out, but if it doesn’t, we could be in for another delay in purchasing. As it is, once we get the go-ahead for funding, it takes about a month for delivery of the system. So we’re currently looking at March delivery.

The good news is, the staff here are eager to volunteer to test out the equipment when we get it!

Well, we’ve decided. We’re going with SMI systems. They offer both a glasses-based and a relatively portable tabletop system. Their tabletop system can be used on not only traditional computer kiosks on a table but also larger screens mounted on a wall, or even projection screens in a theater. Their glasses offer HD resolution “scene video,” that is, the recording of what the subject is looking at over the course of the trial as their field of vision (likely) changes. We got an online walk-through of their powerful software and could see instantly all the statistical methods we could use. After comparing to the systems we saw in Dr. Hornof’s lab, this was the clear winner for use.

Are they a perfect fit? Well, no. They seem to have a relatively small sales force, and that made scheduling a bit of a headache and resulted in a couple of errors in quotes. Those got resolved, but it makes us wonder a bit about how big their technical and support staff is, should we have issues with set up. That was one of our major concerns with another company with a great-looking product, and, if you recall, is one of my personal concerns with fancy new technology. SMI has been around for 20 years, however, and other signs point to them being well-established. They also don’t offer all the features we would love to have in our software in their base package, so they are a bit more expensive overall. But the other company offering a lot of software features was even more expensive and didn’t sell their own hardware. Their hardware isn’t easy to repair ourselves as are some systems that use more off-the-shelf optics. Oh, and they rely on a physical USB “dongle” for their license for the software. None of these outweighed their advantages in the long run.

Now, we have to let down all the other companies, write the grant application, and cross our fingers that the matching funds come through … which we won’t know until January.
