3D Spatial Perception with Real-Time Dense Metric-Semantic SLAM
3D Spatial Perception is the ability of an agent to perceive and understand the three-dimensional structure of its environment, including its position and orientation within that environment. This ability is essential for autonomous robots to navigate and interact with their surroundings, since it …

Hydra: A Spatial Perception Engine for Constructing and Optimizing 3D Scene Graphs in Real-time
… representation for robotics. Scene graphs encode spatial and semantic concepts at multiple levels of abstraction as nodes in a graph, and use edges to represent relationships. Such representations offer an efficient way to model diverse environments, and can be used as an aid for planning tasks …

The Influence of AR Head-Mounted Displays on Spatial Perception and Worker Response in Construction Training
… psychophysiological factors that shape workers' perceptions, attention, and decision-making. The mobility and influence of Augmented Reality Head-Mounted Displays (AR-HMDs) directly interact with these factors by altering how workers perceive their environment, process information, and manage …

Spatial perception on perspective displays as a function of field-of-view and virtual environment enhancements based on visual momentum techniques
… FOV becomes restricted, their ability to acquire spatial information is reduced resulting in a incomplete formulation and representation of the visual world. The magnitude of the resulting biases increase as task difficulty increases. It was predicted that as VM increases in the interface, the …

Effect of dynamic range compression on attending to sounds based on spatial location
… difference (ILD), which is an important cue for spatial perception and attending to sounds in an acoustic mixture. Moreover, natural sounds produce complicated interactions between different sounds in a mixture, as a compressor's gain is driven by whichever source dominates the mixture within a …

Mapping urban perception : how do we know where we are?
… thesis presents a new approach to study urban spatial perception in an efficient, automated, and scalable way. It explores the use of novel tools developed for online surveys and data visualization. Previous studies in human spatial perception have used methods such as face-to-face interviews, …

Performance Enhancements to Visual-Inertial SLAM for Robots and Autonomous Vehicles
Spatial perception is a key enabler for effective and safe operation of robots and autonomous vehicles in unstructured environments. Two key components of a complete spatial perception system are: identifying where the robot is in space, and constructing a representation of the world around the …

Summerfield kindergarten school/community center
… an environment can be developed to excite spatial perception. Through an analysis of case studies, the author will identify issues and elements that could be incorporated into the design of the kindergarten.

Common ground : a Coast Guard station in Boston Harbor
… entity, but an active operator in the act of spatial perception and space-making. Founded on this premise, the thesis seeks to develop techniques and propositions for constructing space and infrastructure in the hostile, ever-changing environment of an island shoreline. To investigate the …

Two intimations of being
… water and fire meet. The gallery is a path of spatial perception and procession. It is filled with elements of movement and the metaphor of birth. This thesis is a search for an architecture that is inseparably universal and inherently specific.

Towards Reinforcement-Learning-based Robot Navigation with 3D Scene Graphs
… to 3DSGs produced online by Hydra, a new spatial perception system that builds 3DSGs in real-time. The work also provides an initial integration of the RL policies previously trained and evaluated in simulation [1] on a Unitree A1 quadruped robot. While the results are too preliminary to …

Encontro entre as práticas Afonjá e Sergipe: o papel do espaço na estabilização do Ilé Àse Òpó Osogunlade
… this work explores alternative forms of spatial perception. In this way, we sought to consider the political implications of establishing a terreiro, investigating what territorial types the movement of establishment connects, disconnects, and which remain latent as possible allies. To …

Toward Integrating Intelligence Into Everything Around Us
… domains, we demonstrate systems that achieve spatial perception, global positioning, and environmental monitoring with orders of magnitude less power than conventional approaches. These innovations enable intelligence in previously impossible contexts: insect-scale robots that navigate complex …

Animation : 2D versus 3D and their combined effect
This thesis studies the differences in the perception of space and character movement between 2D and 3D animation. 2D animation is defined by elements constructed in a 2D environment while 3D animation by elements constructed in a 3D environment. Modern day animated films have been seen to mix the …

Automorphs
… stability. Central to this section is a note on spatial perception ( and therefore 'space' itself) as a function of automorphism, or inherent recursive perceptual thresholds. A graphic presentation of two built projects is meant as an attempt at unified synthesis and application.
