Animation Software
Mobile 3D character platform Mobile platform for quickly generating chat- or interaction-based virtual humans/characters. Allows fast scripting of complex functionality such as speech, nonverbal behavior, lip syncing to speech.

Fast Avatar Capture Software is a tool for automatically capturing a 3D avatar of a human subject in less then a few minutes without a need for a separate operator. From Evan Suma, Andew Feng, Richard Wang, Ari Shapiro

Autorigger and reshaper is a tool for automatically rigging, skinning and reshaping a 3D human body scan obtained from a RGB-D sensor (such as Microsoft Kinect, Intel RealSense, Occipital Structure Sensor and the like) or a 3D scaning cage.

SmartBody is a character animation system that gives an interactive character an extensive set of cpabilities and behaviors, such as: locomotion, steering, object manipulation, speech synthesis, emotional expression, gesturing, physical simulation, gazing among others.

The DANCE software is used for physics-based animation research, including dynamic simulation of rigid bodies, motion capture and dynamic control.

At some point, deepfake videos will be pixel perfect, indistinguishable to the naked eye, and synthetic voice replication will similarly be indistinguishable from a real voice to the human ear. We publish a paper showing that an underlying behavioral signal might be detectable regardless of image quality. paper

BBC News coverage of the Pandorabots/Embody Digital Bot Battle: "Robot Bores: AI-powered awkward first date" https://www.bbc.com/news/technology-54718671




October 21st, 2020
Pandorabots and Embody Digital team up for Bot Battle: an embodied, 3D chat battle between Loebner Prize-winning chatbot Mitsuku from Pandorabots against Facebook's BlenderBot. You can watch the battle on kuki.ai or streaming on Twitch at https://www.twitch.tv/kuki_ai from October 21st, 2020 until November 3rd, 2020. Embody Digital's automatic animation technology powers the characters by converting their text answers into conversational voice, animation and emotion.




June 8th, 2020
Embody Digital reveals its patent for automatically generating movement from text or voice for digital humans and robots. The patent covers input from a conversational AI system into body lanuage and nonverbal behavior derived from those words. So if you want to power a digital human from Google DialogFlow, IBM Watson, Amazon Lex or any other AI, it's likely that this patent covers that process.

Embody Digital's patented software powers robots, avatars, and now...cyborgs... Dr. Peter Scott Morgan, like Stephen Hawking, has 'terminal' motor neuron disease (MND) and will soon be unable to speak or respond physically to others. But he had his voice cloned into a synthetic text-to-speech voice, and his face scanned to produce a 3D digital likeness of himself. And now, using the same assistive technology system that Stephen Hawking used, will be able to engage in conversation through text and power his avatar with emotion and expression through Embody Digital's automated performance system that animates the head, face and lips from simple text and emotion tags, like this:

"[happy] Hello, I am the future. [surprised] For decades to come I will keep Peter's personality [agree] alive and for all the time, I will continue to evolve. [sad] Dying as a human, [happy] living as a cyborg."

Peter describes this as part of becoming 'Peter 2.0', and is an ongoing project with numerous collaborators.

Judge Andy Kelm summarizes his take on Embody Digital, "We found that Embody Digital stood out among a very competitive group of technology-oriented entrants. Not only is the Embody technology novel and innovative, but we also found it to be extremely timely given the significant interest and investment going into AR and VR. We see a wide range of commercial options from skins & emotes in gaming platforms to B2B opportunities like Amazon Sumerian, and we look forward to seeing what the Embody Digital team does next.

Co-presented the DocOn protoype app at the USC Body Computing Conference at USC. My team created a 'digital world expert in cardiology and atrial fibrulation' from Dr. Leslie Saxon. The idea is to 'scale' the reach of a world expert in various health areas and provide information to those that do not have access to such resources. The digital doctor was built using our Rapid Avatar pipeline, the mobile app built using our mobile virtual humans.

Our paper at the ACM SIGGRAPH Conference on Motion in Games in San Francisco won the Best Presentation award! The paper asks the question: "If you could play yourself (scanned avatar) in a video game, would your behavior in the game change?" Short answer = no, but you'd feel more engaged in the game task.

Coverage of Dr. Leslie Saxon's initiative to virtualize doctors as a means to provide additional avenues of communication to medical experts. My team put together a prototype of the virtual doctor using our avatar technologies as an economical way to generate a virtual character of specific person. Typically, creating a photorealistic digital representation of a particular person takes a massive amount of 3D expertise and time. We were able to accomplish this in about 2 days, and today that process would take around 4 hours, making such a representation economically viable for a large number of people. You can see my researcher Andrew Feng with Dr. Leslie Saxon doing facial capture.

My summer intern, Marco Volino, put together a 100-camera photogrammetry cage based on Raspberry Pis for his summer project in my lab. The result is that we can now consruct a high-quality 3D model from a body scan in about 15 minutes. The video show some results from the system and includes many of USC ICT's summer interns (everybody loved to be scanned and see themselves in 3d...)

Here is a Gizmodo article on our Rapid Avatar Capture and Simulation project where we can capture a person using a first-generation Microsoft Kinect system and simulate them in a matter of minutes.

GIZMODO - Kinect Avatar Creation at USC from Gizmodo on Vimeo.



We believe that this kind of capability dramatically changes the economics of avatar capture (essentially, it's now free and takes very little time) and will have an impact on 3D character acquisition and use going forward.

Here's a video of the entire capture process:




March, 2013
I volunteered for a project out of ICT's Graphics Lab. My face and performance were captured by their Light Stage (I was not involved with the technical aspects). Here are the results, as shown on different technological platforms by both Nvidia:



and Activision:



In the days following the capture, I would walk by my colleagues in the Graphics Lab (my office is very close to theirs) and they would be studying me very closely as I walked by. Occassionally they would say things like "You should see what we are doing to 'Ari' today.". In didn't take long before I insisted that they call my digital doppleganger 'Ira' instead of 'Ari' to loosen some of this association between myself and this digital version of myself. You can do what you want with Ira; it gets a little personal when you are doing it to 'me'. I'm sure that as this phenomena of capturing a person and digitizing them, then putting their digital version in various situations will lead to a number of psychological studies, particularly now that the distinction between the two is getting smaller and smaller.

In case you are curious, the 'yogurt parfait' incident came when the director (Oleg Alexander from ICT) asked me to get mad about something so that they could record some kind of emotional expression. About a week before the capture session, I had stopped by McDonalds in the morning for their $1 sausage muffin (substituting sausage for egg) and the $1 fruit and yogurt parfaits, as I had done so a few times a week for the past month. Usually the strawberries are a bit too cold, and sometimes frozen, so I would typically eat the yogurt, and would sometimes not even touch the strawberries, depending on how icy and cold they were. That one day, they gave me an entire plastic cup full of frozen, hard strawberries without a bit of yogurt, which I didn't realize until I left the drive through. I came back the next day, I asked for a refund, then asked the cashier to check the parfaits and make sure that there is enough yogurt in them. This turned into an unpleasant exchange with the manager on duty, who insisted that all parfaits are exactly the same, and that it would have been impossible to get a parfait that lacked yogurt, and refused to check any of the existing parfaits for their yogurt content (I still wanted another one...) I then wrote a complaint to McDonalds via email. They sent me a coupon for a free meal, told me they took my complaint seriously, and told me they would talk to the manager at that restaurant. That was about as much effort I wanted to put into a defective $1 purchase. I went back to that McDonalds several weeks later, and noticed the manager wearing a different, what appeared to be, a more formal, uniform, and the cashier also for the first time refused to substitute sausage for egg anymore in the $1 sausage mcmuffin. So I assume that someone talked to the owner and the manager, and among other things, a decision was made to not allow substitutions anymore. Not sure what happened to the parfaits - I stopped buying them. I suspect that my complaint set in motion a number of things. All in all, I stopped frequenting there for breakfast. So it's nice that Digital Ira can carry on my message without any additional effort on my part (how long do things last on the Internet, these days? Forever?), and stand up for the little guy against the corporate multinational.

Here's a fun parody of the yogurt ordeal:
