Berkeley Puppet Interview Manual Muscle

Berkeley Puppet Interview (BPI)Since the first publication of psychometric data in 1998 (Measelle, Ablow, Cowan, & Cowan, 1998, Child Development ), the Berkeley Puppet interview (BPI) has been included as a measure in over 100 published peer-reviewed studies, has been translated into 7 different languages, and has been identified as an “evidence based” assessment tool for preschoolers and children ages 4 to 8 years.Please click here to see a list of training workshops and labs that have used the BPI (list). Overview of the BPIThank you for your interest in the Berkeley Puppet Interview (BPI). The BPI, building on a rich tradition of using puppets in clinical and research applications, was developed (Ablow & Measelle, 1993) to address the absence of standardized methodologies appropriate for measuring young children's perceptions of themselves and their environments.

Using an interactive technique for interviewing children, the BPI blends structured and clinical interviewing methods. During the actual BPI interview, two identical hand puppets (tan-colored puppy dogs named 'Iggy' and 'Ziggy') make opposing statements about themselves and then ask children to describe themselves.

Andrew GodbehereNAN: You are currently working toward your Electrical Engineering PhD at the University of California, Berkeley. Can you describe any of the electronics projects you’ve worked on?ANDREW: In my final project at Cornell University, I worked with a friend of mine, Nathan Ward, to make wearable wireless accelerometers and find some way to translate a dancer’s movement into music, in a project we called CUMotive. The computational core was an Atmel ATmega644V connected to an Atmel AT86RF230 802.15.4 wireless transceiver. We designed the PCBs, including the transmission line to feed the ceramic chip antenna. Everything was hand-soldered, though I recommend using an oven instead. We used Kionix KXP74 tri-axis accelerometers, which we encased in a lot of hot glue to create easy-to-handle boards and to shield them from static.

This is the central control belt-pack to be worn by a dancer for CUMotive, the wearable accelerometer project. An Atmel ATmega644V and an AT86RF230 were used inside to interface to synthesizer. The plastic enclosure has holes for the belt to attach to a dancer. Wires connect to accelerometers, which are worn on the dancer’s limbs.The dancer had four accelerometers connected to a belt pack with an Atmel chip and transceiver. On the receiver side, a musical instrument digital interface (MIDI) communicated with a synthesizer. (Design details are available at.)I was excited about designing PCBs for 802.15.4 radios and making them work.

I was also enthusiastic about trying to figure out how to make some sort of music with the product. We programmed several possibilities, one of which was a sort of theremin; another was a sort of drum kit. I found that this was the even more difficult part—not just the making, but the making sense.When I got to Berkeley, my work switched to the theoretical.

I tried to learn everything I could about robotic systems and how to make sense of them and their movements.NAN: Describe the real-time machine vision-tracking algorithm and integrated vision system you developed for the “Are We There Yet?” installation.ANDREW: I’ve always been interested in using electronics and robotics for art. Having a designated emphasis in New Media on my degree, I was fortunate enough to be invited to help a professor on a fascinating project. This view of the Yud Gallery is from the installed camera with three visitors present. Note the specular reflections on the floor. They moved throughout the day with the sun.

This movement needed to be discerned from a visitor’s typical movement.For the “Are We There Yet?” installation, we used a PointGrey FireFlyMV camera with a wide-angle lens. The camera was situated a couple hundred feet away from the control computer, so we used a USB-to-Ethernet range extender to communicate with the camera.We installed a color camera in a gallery in the Contemporary Jewish Museum in San Francisco, CA. We used Meyer Sound speakers with a high-end controller system, which enabled us to “position” sound in the space and to sweep audio tracks around at (the computer’s programmed) will.

The Meyer Sound D-Mitri platform was controlled by the computer with Open Sound Control (OSC). This view of the Yud Gallery is from the perspective of the computer running the analysis. This is a probabilistic view, where the brightness of each pixel represents the “belief” that the pixel is part of an interesting foreground object, such as a pedestrian. Note the hot spots corresponding nicely with the locations of the visitors in the image above.The hard work was to then program the computer to discern humans from floors, furniture, shadows, sunbeams, and cloud reflections. The gallery had many skylights, which made the lighting very dynamic.

Then, I programmed the computer to keep track of people as they moved and found that this dynamic information was itself useful to determine whether detected color-perturbance was human or not.Once complete, the experience of the installation was beautiful, enchanting, and maybe a little spooky. The audio tracks were all questions (e.g., “Are we there yet?”) and they were always spoken near you, as if addressed to you. They responded to your movement in a way that felt to me like dancing with a ghost. You can watch videos about the installation at.The “Are We There Yet?” project opens itself up to possible use as an embedded system. I’ve been told that the software I wrote works on iOS devices by the start-up company Romo , which was evaluating my vision-tracking code for use in its cute iPhone rover. Further, I’d say that if someone were interested, they could create a similar pedestrian, auto, pet, or cloud-tracking system using a Raspberry Pi and a reasonable webcam.I may create an automatic cloud-tracking system to watch clouds. I think computers could be capable of this capacity for abstraction, even though we think of the leisurely pastime as the mark of a dreamer.NAN: Some of the projects you’ve contributed to focus on switched linear systems, hybrid systems, wearable interfaces, and computation and control.

Tell us about the projects and your research process.ANDREW: I think my research is all driven by imagination. I try to imagine a world that could be, a world that I think would be nice, or better, or important. Once I have an idea that captivates my imagination in this way, I have no choice but to try to realize the idea and to seek out the knowledge necessary to do so.For the wearable wireless accelerometers, it began with the thought: Wouldn’t it be cool if dance and music were inherently connected the way we try to make it seem when we’re dancing? From that thought, the designs started. I thought: The project has to be wireless and low power, it needs accelerometers to measure movement, it needs a reasonable processor to handle the data, it needs MIDI output, and so forth.My switched linear systems research came about in a different way. As I was in class learning about theories regarding stabilization of hybrid systems, I thought: Why would we do it this complicated way, when I have this reasonably simple intuition that seems to solve the problem?

I happened to see the problem a different way as my intuition was trying to grapple with a new concept. Cambiare software autoradio cinesesc. That naive accident ended up as a publication, “Stabilization of Planar Switched Linear Systems Using Polar Coordinates,” which I presented in 2010 at Hybrid Systems: Computation and Control (HSCC) in Stockholm, Sweden.NAN: How did you become interested in electronics?ANDREW: I always thought things that moved seemingly of their own volition were cool and inherently attention-grabbing. I would think: Did it really just do that? How is that possible? Andrew worked on this project when computers still had parallel ports. A—This photo shows manually etched PCB traces for a digital EKG (the attempted EEG) with 8-bit LED optoisolation. The rainbow cable connects to a computer’s parallel port.

The interface code was written in C and ran on DOS. B—The EKG circuitry and digitizer are shown on the left. The 8-bit parallel computer interface is on the right. Connecting the two boards is an array of coupled LEDs and phototransistors, encased in heat shrink tubing to shield against outside light.Electric rally-car tracks and radio-controlled cars were a favorite of mine.

I hadn’t really thought about working with electronics or computers until middle school. Before that, I was all about paleontology. Then, I saw an episode of Scientific American Frontiers, which featured Alan Alda excitedly interviewing RoboCup contestants. Watching RoboCup a soccer game involving robotic players, I was absolutely enchanted.While my childhood electronic toys moved and somehow acted as their own entities, they were puppets to my intentions.

Watching RoboCup, I knew these robots were somehow making their own decisions on-the-fly, magically making beautiful passes and goals not as puppets, but as something more majestic. I didn’t know about the technical blood, sweat, and tears that went into it all, so I could have these romantic fantasies of what it was, but I was hooked from that moment.That spurred me to apply to a specialized science and engineering high school program.

It was there that I was fortunate enough to attend a fabulous electronics class (taught by David Peins), where I learned the basics of electronics, the joy of tinkering, and even PCB design and assembly (drilling included). I loved everything involved. Even before I became academically invested in the field, I fell in love with the manual craft of making a circuit.NAN: Tell us about your first design.ANDREW: Once I’d learned something about designing and making circuits, I jumped in whole-hog, to a comical degree. My very first project without any course direction was an electroencephalograph!I wanted to make stuff move on my computer with my brain, the obvious first step. I started with a rough design and worked on tweaking parameters and finding components.In retrospect, I think that first attempt was actually an electromyograph that read the movements of my eye muscles. And it definitely was an electrocardiograph.

Success!Someone suggested that it might not be a good idea to have a power supply hooked up in any reasonably direct path with your brain. So, in my second attempt, I tried to make something new, so I digitized the signal on the brain side and hooked it up to eight white LEDs.

On the other side, I had eight phototransistors coupled with the LEDs and covered with heat-shrink tubing to keep out outside light. That part worked, and I was excited about it, even though I was having some trouble properly tuning the op-amps in that version.NAN: Describe your “dream project.”ANDREW: Augmented reality goggles. I’m dead serious about that, too. If given enough time and money, I would start making them.I would use some emerging organic light-emitting diode (OLED) technology. I’m eyeing the start-up MicroOLED for its low-power “near-to-eye” display technologies. They aren’t available yet, but I’m hopeful they will be soon.

I’d probably hook that up to a Raspberry Pi SBC, which is small enough to be worn reasonably comfortably.Small, high-resolution cameras have proliferated with modern cell phones, which could easily be mounted into the sides of goggles, driving each OLED display independently. Then, it’s just a matter of creativity for how to use your newfound vision! The OpenCV computer vision library offers a great starting point for applications such as face detection, image segmentation, and tracking.Google Glass is starting to get some notice as a sort of “heads-up” display, but in my opinion, it doesn’t go nearly far enough. Here’s the craziest part—please bear with me—I’m willing to give up directly viewing the world with my natural eyes, I would be willing to have full field-of-vision goggles with high-resolution OLED displays with stereoscopic views from two high-resolution smartphone-style cameras.

(At least until the technology gets better, as described in Rainbows End by Vernor Vinge.) I think, for this version, all the components are just now becoming available.Augmented reality goggles would do a number of things for vision and human-computer interaction (HCI). First, 3-D overlays in the real world would be possible.Crude example: I’m really terrible with faces and names, but computers are now great with that, so why not get a little help and overlay nametags on people when I want?

Another fascinating thing for me is that this concept of vision abstracts the body from the eyes. So, you could theoretically connect to the feed from any stereoscopic cameras around (e.g., on an airplane, in the Grand Canyon, or on the back of some wild animal), or you could even switch points of view with your friend!Perhaps reality goggles are not commercially viable now, but I would unabashedly use them for myself. I dream about them, so why not make them?
