Widespread adoption of artificial intelligence (AI) technologies is substantially affecting the human condition in ways that are not yet well understood. Negative unintended consequences abound including perpetuation and exacerbation societal inequalities divisions via algorithmic decision making. We present six grand challenges for scientific community to create AI human-centered, is, ethical, fair, enhance condition. These result an international collaboration across academia, industry...
The all-pairs shortest-path problem is an intricate part in numerous practical applications. We describe a shared memory cache efficient GPU implementation to solve transitive closure and the on directed graphs for large datasets. proposed algorithmic design utilizes resources available NVIDIA G80 architecture using CUDA API. Our solution generalizes handle graph sizes that are inherently larger then DRAM GPU. Experiments demonstrate our method able significantly increase processing making...
We present the Robotic Modeling Assistant (RoMA), an interactive fabrication system providing a fast, precise, hands-on and in-situ modeling experience. As designer creates new model using RoMA AR CAD editor, features are constructed concurrently by 3D printing robotic arm sharing same design volume. The partially printed physical then serves as tangible reference for she adds elements to her design. RoMA's proxemics-inspired handshake mechanism between allows quickly interrupt access area...
There has been a recent paradigm shift in the computer animation industry with an increasing use of pre-recorded motion for animating virtual characters. A fundamental requirement to using capture data is efficient method indexing and retrieving motions. In this paper, we propose flexible, searching arbitrarily complex motions large databases. Motions are encoded keys which represent wide array structural, geometric and, dynamic features human motion. Keys provide representative search space...
The illumination and appearance of the solar/skydome is critical for many applications in computer graphics, vision, daylighting studies. Unfortunately, physically accurate measurements this rapidly changing source are difficult to achieve, but necessary development physically-based sky models comparison studies existing simulation models. To obtain baseline data time-dependent anisotropic light source, we design a novel acquisition setup simultaneously measure comprehensive properties. Our...
Optimal heuristic searches such as A* search are commonly used for low-dimensional planning 2D path finding. These algorithms however, typically do not scale well to high-dimensional problems motion robotic arms, computing trajectories non-holonomic vehicles and synthesis humanoid characters. A recently developed randomized version of search, called R* scales higher-dimensional by trading off deterministic optimality guarantees probabilistic sub-optimality guarantees. In this paper, we show...
Abstract Aging and imperfections provide important visual cues for realism. We present a novel physically‐based approach simulating the biological aging decay process in fruits. This method simulates interactions between multiple processes. Our biologically‐derived, reaction‐diffusion model generates growth patterns areas of fungal bacterial infection. Fungal colony spread propagation is affected by both nutrient depletion. changes physical properties surface fruit as well its internal...
Humans become visibly tired during physical activity. After a set of squats, jumping jacks or walking up flight stairs, individuals start to pant, sweat, loose their balance, and flush. Simulating these physiological changes due exertion exhaustion on an animated character greatly enhances motion's realism. These fatigue factors depend the mechanical, physical, biochemical function states human body. The difficulty simulating for animation is in part complex anatomy We present multi-modal...
Augmented Reality (AR) tools have shown significant potential in providing on-site visualization of Building Information Modeling (BIM) data and models for supporting construction evaluation, inspection, guidance. Retrofitting existing buildings, however, remains a challenging task requiring more innovative solutions to successfully integrate AR BIM. This study aims investigate the impact AR+BIM technology on retrofitting training process assess future usage. We conducted with 64 non-expert...
In this paper we investigate the utility of an interactive, desktop-based virtual reality (VR) system for training personnel in hazardous working environments. Employing a novel software model, CRAM (Course Resource with Active Materials), asked participants to learn specific aircraft maintenance task. The evaluation sought identify type familiarization that would be most useful prior hands on training, as well after, skill maintenance. We found develop increased awareness hazards when...
Early Islamic light sources are not simple, static, uniform points, and the fixtures themselves often combinations of glass, water, fuel flame. Various physically based renderers such as Radiance widely used for modeling ancient architectural scenes; however they rarely capture true ambiance environment due to subtle lighting effects. Specifically, these fail correctly model complex caustics produced by glass fixtures, water level, sources. While original 8th through 10th century Mosque...
Building facades are components that shape a structure's daylighting, energy use, and view factors. This paper presents an approach enables designers to understand the impact different facade designs will have over time space in built environment through BIM-enabled augmented reality system. The system permits examination of range retrofit scenarios visualizes daylighting simulations aesthetics structure while retaining function comfort. A focus our study was measure how participants make...
Increased strain on the hospitality industry following COVID-19 pandemic and ensuing labor shortages has led to calls for new technologies such as smartwatches understanding improving work conditions housekeepers, who are often from vulnerable marginalized populations. In addition concerns regarding how will be received by workers, questions remain whether metrics derived can usefully predict aspects of worker experience, feelings stress. We recruited 20 hotel housekeepers wear...
