On October 23rd, the UC Learning Centers hosted the annual tech fair for students who were interested in playing with equipment relating to AR/VR. It was also a great opportunity to expose them to various use cases and to encourage them to explore different careers options within STEM. The following are some shots taken at the fair as students trickled in to connect with various booths and play with the demoes.

Along with Makerspace, UCLA Esports, Bird, and other vendors, there was a dedicated booth to showcase Augmented Reality in which Anthony Caldwell (the Manager and Resident Technologist at the Scholarly Innovation Lab in YRL) deployed using Vectorworks. Many of the students were wowed by the ease of use as we showed them how to easily upload a 3D model created through Vectoworks into the cloud where it takes anywhere from 10 – 30 seconds of construction until it appear on your IPAD through their dedicated app. 

More companies are finding it lucrative and time-saving to invest in integrated features that lower the entry level to immersive experiences. It’s important for students to learn about the ever-changing technological space. Tools like those presented allow users to spend more time creating and scoping the content rather than wrestling with the interface itself.

The Laboratory of Neuromodulation & Neuroimaging: Your Brain’s Never Looked so Good

At some point I’m going to sound like a broken record when I keep saying how amazing the experiences of each of these visits are. There are only so many superlatives that can be thrown around until they start to lose their meaning. Before that happens, however, we should reserve some for Dr Nanthia Suthana’s lab, because it was an amazing tour with a remarkably generous host and obliging postdocs, each ready to engage with visitors to discuss their work and their equipment. (To say that they were incredibly knowledgeable about everything would be to state the obvious.)

One of Dr Suthana’s research labs.

Visitors are immediately struck by the large, open space surrounded by 24 infrared base stations placed throughout the room. These sensors are integrated with all of the VR equipment in the space, and are used to not only set virtual boundaries, but are also meant to track markers. They are capable of sub-millimeter motion tracking, so don’t move. Or do move, depending on what they need.

The light grey balls on the top of the headset are the kinds of markers that the infrared base stations are tracking. These markers bounce back the infrared signals that are then picked up by the base stations to keep track of the subject’s movement. Entire motion tracking suits are in the space to allow for even greater motion capturing.

The entire space boasts an impressive amount of hardware. Some of it includes:

  • 24 OptiTrack base stations
  • A Magic Leap AR headset
  • Microsoft Hololens
  • HTV Vive complete with a Tobii eye tracking attachment
  • Samsung VR Headset with SMI eye tracking
  • Motion capture suits of various sizes
  • Eva Artec Scanner and automatic rotating platform
  • BioPac – state of the art biometric measurements
  • ANT Neuro eego sport 64 channel mobile EEG system 
They also have this eye tracking headset from Pupil Labs, made to look even goofier because the goof in the picture doesn’t know why WordPress is flipping his photo and can’t seem to figure out how to rotate the damn thing. (For the record, I’ve since figured it out but I’m leaving this as is because otherwise I wouldn’t be able to call myself a goof.)

So what do they do with all this stuff? Well, a whole hell of a lot as it turns out. For starters, the Vive headset station is a great example of cross-campus collaboration. The environments created for the Vive are for educational purposes. Yea, you guessed it, they’re teaching folks about the brain.

This particular program was design by Dr Rebecca Allen, professor of 3D media art whose work centers around creative expression in virtual and augmented reality. In this screenshot you can see that I’ve already taken apart different pieces of the brain, each part named as though scientists picked random words from a Latin dictionary.

Here I have detached yet another chunk from the brain. The model was quite large, and I was able to virtually place my head in the middle of the brain, using the controllers to highlight different sections of the brain. They claimed that by this time the person would have died from all the missing parts of their brain, but I’m not too sure.

The Magic Leap was probably my favorite experience. I’d never really done AR before, and this was probably one of the best environments in which to do it. I mean, I don’t know about you, but I don’t have 24 OptiTrack base stations at home. The 18 that I have just don’t seem to cut it.

Here I am, wearing the Magic Leap, deftly and bravely defending everyone from attacking robots while they just chit-chat in blissful ignorance of the imminent danger all around them. Let me just say that if you’re an alien robot climbing out of the walls you better watch your ass – I’m a crack shot.


In addition to various AR environments that I got to experience with the Magic Leap, the most impressive thing about the lab is the research that they are conducting.

Patients with epilepsy are sometimes given an implant that resides within the skull, on the brain, with wires that go into the brain itself. Now, I don’t know if you know this, but I’m not a neuroscientist – I don’t even know if I spelled that correctly. But from what I could gather, these wires are meant to stimulate the brain in such a way as to alleviate epileptic episodes.

That’s all well and good, but these implants were traditionally just one-way streets. Nowadays, many implants are of a new, recently-FDA-approved, variety. These implants perform the same functions as the aforementioned ones (that is, if I got that right in the first place), but are a two-way street. They can be connected to from the outside, and they can send data about what’s going on inside the brain. Again, not a neuroscientist, but basically these wires send electric signals into the brain but also can read and send out information about what’s going on deep inside the brain.

The idea is that by reading these epilepsy implants while subjects are engaging in various VR environments, Dr Suthana and her researchers can monitor brain activity when a person is up and about, engaged instead of lying in a coffin getting an MRI scan. Here’s Cory Inman, Post-Doc in the lab, wearing the AR headset to shoot robots or pet penguins.

Some of the environments developed for this implant research revolve around memory. I, of course, passed the test with flying colors but I don’t remember what my score was.

Subjects would wear special caps that could read the information being sent by the implant’s wires that were deep in the brain. The wires were in the hippocampus or hippopotamus or something to study memory as subjects engaged in an AR environment designed to test their memory.

Special thanks to Cory Inman, PostDoc researcher, Diane Villaroman the resident programmer analyst, and Sonja Hiller, research assistant and lab manager.

Definitely some interesting research going on here, and if you can think of some kind of partnership or research project, don’t email me, email Dr Suthana.
