Title: "Butterfly Effects" in Perceptual Development
Abstract: A young child's difficulties with face recognition led us to explore how atypicalities in early perceptual development can impact later proficiencies. In the specific context of children who have been created for congenital blindness, we and others have found some consistent deficits in post-operative face recognition performance. These deficits have typically been attributed to the pre-operative deprivation the children experienced during 'sensitive periods' of development. However, we suggest that there may be an additional factor at work: Differences in *post-operative* visual experiences of newly-sighted children relative to those of typically developing infants. These differences may skew early visual learning and lead to abnormalities in recognition processes. We call these 'butterfly effects' given that they involve potentially large consequences of small initial perturbations in visual experience. Such hypothesized butterfly effects have relevance for three goals: 1. accounting for observed deficits in newly-sighted children, 2. understanding why some aspects of normal visual development unfold in the way they do, and 3. formulating effective training regimens for computational vision systems.

Title: Using Data while Protecting Privacy in the Digital Era
Abstract: We live in a time when information about most of our movements and actions is collected and stored in real time. The availability of large-scale behavioral data dramatically increases our capacity to understand and potentially affect the behavior of individuals and collectives.
The use of this data, however, raises legitimate privacy concerns. Anonymization is meant to address these concerns: allowing data to be fully used while preserving individuals' privacy. In this talk, I will first discuss how traditional data protection mechanisms fail to protect people's privacy in the age of big data. More specifically, I will show how the mere absence of obvious identifiers such as name or phone number or the addition of noise are not enough to prevent re-identification. Second, I will describe what I see as a necessary evolution of the notion of data anonymization towards an anonymous use of data. I will then conclude by discussing some of the modern privacy engineering techniques currently developed to allow large-scale behavioral data to be used while giving individual strong privacy guarantees.

Title: Human-centric Vision in the Real World: Challenges and Opportunities
Abstract: Human-centric vision, or the ability of machines to perceive and analyze humans, is the gateway to human-computer interaction (HCI). It is foundational technology, which is an essential component of any AI system with wide-ranging applications across product categories. From our nascent successes of shipping face detection solutions in digital cameras some fifteen years ago, HCI has witnessed phenomenal growth. Today, many successful and robust HCI technologies are ubiquitous in everyday products from cell phones to cars, including those for face, gaze and body tracking, and face recognition. Much of this growth has been driven by the availability of large and diverse datasets, adequate compute power and the advent of deep learning. However, we are only just getting started and much exciting new work lays ahead. In this talk, I will describe several cutting-edge HCI technologies that we have invented at NVIDIA along with our journey of converting them into successful real-world shipped products. I will describe open challenges encountered along the way, which present rich opportunities for continued research and development in the field. Finally, I will close with thoughts on what lays ahead, both in terms of unexplored/underdeveloped fundamental HCI technologies and the exciting novel applications areas that they can enable in the future.

Title: Customer Behavior (Demand) Prediction in Brick-and-Mortar Stores from Product Recognition
Abstract: Although e-commerce accounts for more and more of total retail sales over the past decades, traditional brick-and-mortar stores still account for over 70% of total sales. Certain categories of retail businesses, such as convenience stores, still offer a unique value that online retailers cannot compete with: the ability to quickly and easily walk in and out to obtain what you want in just a few minutes.
Meanwhile, how to increase the operation efficiency of brick-and-mortar stores by leveraging digital transformation, akin to that of e-commerce, caught the attention from industry, sometimes dubbed the name “new retail.” To achieve this, the first step is to transform the real-world physical information from the brick-and-mortar stores into digital form, where computer vision plays an essential role. Then, we may build and apply mathematical models to infer key customer behaviors such as their demands of different products, which naturally leads to optimized decisions of key operation steps such as assortment planning.
In this talk, I will elaborate on and share how we may directly infer customer shopping behaviors from the product display map (combined with product sales records). Such product display maps represent how each product is presented in the shelf, which are obtained through a full digitization of the storefront, i.e., recognizing shelves and estimating their poses, recognizing products along with in-shelf positions using state-of-the-art computer vision technologies. The system built upon these technologies are running 24/7 in our storefronts at Convenience Bee, a new and fast-growing convenience store chain in mainland China. I will use real data from our stores to illustrate the technologies behind.

Title: How Does Our Body Talk, Think, and Interact in Face-to-Face Language Use?
Abstract: Most research on language has focused on spoken and written language only. However when we use language in face-to-face interactions we use not only speech but also use our bodily actions, such as gestures in meaningful ways to communicate our messages and in ways closely linked to the spoken aspects of our language. For example we can enhance or complement our speech with a drinking gesture, as we say “we stayed up late last night”. In this talk I will summarize research that investigates how such meaningful bodily actions are recruited in using language as a dynamic, adaptive and flexible system and how gestures interact with speech during production and comprehension of language and in dialogic contexts at the behavioral, cognitive, and neural levels. I will also touch upon how novel kinematic analyses techniques using OPEN POSE and KINECT help us see the “invisible” in visible communicative expressions. Overall I will claim that multimodal uses of language contribute significantly to how language can be recruited as a flexible and adaptive system for enhancing human cognition and communication and that we need more technological advances to understand the complexities of this uniquely human capacity

Title: Why Regulate Facial Recognition and Surveillance Technologies?
Abstract: Face recognition as a biometric is widely used, and provides benefits of convenience, improved accessibility, and better law enforcement. However, it is open to numerous criticisms as a surveillance technology, including problems associated with its various biases, with its potential misuses by corporations and oppressive governments, and with the psychological effects it has on the population, when people are put under constant surveillance. While there are other technologies that are potentially much more ubiquitous and powerful for surveillance (such as mobile phones, or web browsers), face recognition technology represents an observing eye, and has an uncanny symbolic power. In the last few years, we have seen an increased pressure from the public to regulate the use of face recognition in various scenarios, across the globe, in parallel with an accelerated technology push for developing systems at massive scales. In this talk, I would like to continue the discussions that started in FG'20 about the role played by the researchers and developers of technology in this debate, in the light of recent developments.
