Sparse-view Pose Estimation and Reconstruction via Analysis by Generative Synthesis

3305 Newell-Simon Hall

Abstract:  This talk will present our approach for reconstructing objects from sparse-view images captured in unconstrained environments. In the absence of ground-truth camera poses, we will demonstrate how to utilize estimates from off-the-shelf systems and address two key challenges: refining noisy camera poses in sparse views and effectively handling outlier poses.   Bio:  Qitao is a second-year [...]

EgoTouch: On-Body Touch Input Using AR/VR Headset Cameras

3305 Newell-Simon Hall

Abstract:  In augmented and virtual reality (AR/VR) experiences, a user’s arms and hands can provide a convenient and tactile surface for touch input. Prior work has shown on-body input to have significant speed, accuracy, and ergonomic benefits over in-air interfaces, which are common today. In this work, we demonstrate high accuracy, bare hands (i.e., no special [...]

Auptimize: Optimal Placement of Spatial Audio Cues for Extended Reality

3305 Newell-Simon Hall

Abstract:  Spatial audio in Extended Reality (XR) provides users with better awareness of where virtual elements are placed, and efficiently guides them to events such as notifications, system alerts from different windows, or approaching avatars. Humans, however, are inaccurate in localizing sound cues, especially with multiple sources due to limitations in human auditory perception such as [...]

Abstraction Barriers for Embodied Algorithms

1403 Tepper School Building

Abstract: Designing robotic systems to reliably modify their environment typically requires expert engineers and several design iterations. This talk will cover abstraction barriers that can be used to make the process of building such systems easier and the results more predictable. By focusing on approximate mathematical representations that model the process dynamics, these representations can [...]

Autonomous Robotic Surgery: Science Fiction or Reality?

1403 Tepper School Building

Abstract:  Robotic assisted surgery (RAS) systems incorporate highly dexterous tools, hand tremor filtering, and motion scaling to enable a minimally invasive surgical approach, reducing collateral damage and patient recovery times. However, current state-of-the-art telerobotic surgery requires a surgeon operating every motion of the robot, resulting in long procedure times and inconsistent results. The advantages of [...]

Generative Modelling for 3D Multimodal Understanding of Human Physical Interactions

3305 Newell-Simon Hall

Abstract: Generative modelling has been extremely successful in synthesizing text, images, and videos. Can the same machinery also help us better understand how to physically interact with the multimodal 3D world? In this talk, I will introduce some of my group's work in answering this question. I will first discuss how we can enable 2D [...]

A retrospective, 40 Years of Field Robotics

CIC CIC Buuilding Conference Room 1, LL Level

Abstract: Chuck has been building and deploying robots in the field for the past 40 years.  In this retrospective he will touch on the robots, people and experiences that have been part of the journey.  From the early days in the 1980s with the Three Mile Island nuclear robots and the first outdoor autonomy robots [...]

High-resolution cloth simulation in milliseconds: Efficient GPU Cloth Simulation with Non-distance Barriers and Subspace Reuse Interactions

3305 Newell-Simon Hall

Abstract: We show how to push the performance of high-resolution cloth simulation, making the simulation interactive (in milliseconds) for models with one million degrees of freedom (DOFs) while keeping every triangle untangled. The guarantee of being penetration-free is inspired by the interior-point method, which converts the inequality constraints to barrier potentials. Nevertheless, we propose a [...]
