Effects of Visual-Vestibular Interactions on Navigation Tasks in Virtual Environments
(2016-09-01)Virtual environments (VEs) are increasingly used as a safe, cost-effective way to train first responders and military units to search buildings and urban environments. Trainees typically view the VE on a computer screen ... -
Eikonal+ training and simulation platform: enabling a new generation of optical systems
(2017)The year of 2016 was proclaimed by many to be the year of virtual/augmented reality [Forbes]. The public attention was captured by the idea of wearable and immersive devices that can be used for communication, training, ... -
Enhancing Training and Presence in Virtual Environments Using Passive Haptics
(2001)One of the worst virtual environment experiences is to virtually contact something and feel nothing. Visual-haptic sensory conflicts are normally dominated by visual perception. Therefore, augmenting a high-fidelity ... -
Evaluating and Training Intraoperative Analysis of the Mitral Valve
(2013)Mitral valve repair is the recommended method of treating valve incompetency. However, the procedure is quite difficult and, as a result, underperformed due to surgeon’s need to predict the closed valve shape of the ... -
Evaluating Augmented Reality for Space Telerobotics Training
(2018)Despite the extensive previous research into manual tracking, to the author’s knowledge there exists no study in the literature addressing human performance or workload changes in manual tracking tasks between traditional ... -
Haptic-based Dental Procedure Training Simulator
(2005)Since the beginning of the last century, simulators have been widely used in military and aviation. Recently, the use of simulation in medicine and dentistry has brought the attention of the research community, looking ... -
Haptics-based Cataract Surgery Simulator
(2015-09-01)Surgical training using computer-based simulators are being adopted by many medical specialties, mainly because they offer several advantages to traditional training methods involving animals or cadavers. This article ... -
A Hard-Real-Time Juggling Simulator to Shape Human Sensitivity to Cues and Coordination of Muscles
(2018)Many virtual reality tasks incorporate auditory and haptic (or touch) feedback, in addition to visual displays of spatial information. Non-visual feedback modalities such as the former increase realism; but they may have ... -
Human-Automation Interaction Testbed for Evaluating User Control Methods and Training
(2020)In a complex work environment, an operational challenge may be controlling the multitude of independent objects that are required for a manual task and/or object manipulation, such as experienced by astronauts, surgeons, ... -
Hybrid Force-Feedback Control for Virtual Environments
(1998)The scope of this project is the design and implementation of a force-feedback device that utilizes brakes as well as motors for hybrid force control.. The device is a pen-sized device for planar point force-feedback. ... -
Image-Driven Simplification and Optimization of Polygonal Models
(2000)Model simplification is often used in computer graphics to reduce the complexity of large polygonal models. For many graphics applications, the goal of this process is to produce a coarser model that is visually similar ... -
Interactive Ecosystem for Surgical Training in a Realistic Mixed-Reality
(2020)In many surgical procedures, surgeons rely on their general knowledge of anatomy and relatively crude measurements, which have inevitable uncertainties in locating internal anatomical targets. One example procedure that ... -
Interactive Training of Teleoperated Robotic System for Real-time MRIGuided Steerable Needle Intervention
(2016-09-01)Needle-based interventions, also known as percutaneous interventions, are common approaches for diagnostic and therapeutic procedures including tissue biopsy, delivery of therapeutic agents and tumor ablation. Needle ... -
Investigation of Egocentric and Exocentric Distance Perception in Virtual Environments: Application to Enhance Transfer of Training in Multi-model Ves
(2005)In this report we summarize the results for three experiments completed during the Link Fellowship period. The aim of the first and second experiments were to test the efficacy of a novel assessment procedure for determining ... -
Knowledge Structures: An End to the Redundancy And the Confusion
(1997)Situation awareness (SA) is most commonly defined as "the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the ... -
Learning Meaningful Representations of Surgical Motion Without Annotations
(2019)Superior technical skill in the operating room is associated with better patient outcomes [3,18], and at the core of surgical education is the belief that technical skill is improved through deliberate practice and appropriate ... -
Mobile in-situ visualization
(2017-09-01)In this work we present a new distributed technique to geometrically calibrate multiple projectors on a fiducial free arbitrary surface using multiple casually aligned cameras where every point of the surface is seen by ... -
Modeling Self-Organization in Human Crowds
(2020)Developing an understanding of human crowd movement is critical for optimizing crowd safety, both on the streets and in buildings. It is well understood from the study of animal collective motion that individuals are ... -
A New Object Representation For Graphics
(1999)M-reps are a multiscale approach to the modeling and rendering of 30 solid geometry. Traditional geometric models, whether b-reps or CSG, are represented at infinitesimal spatial scale and then require simplification ... -
A Nonlinear Motion Cueing Algorithm With a Human Perception Model
(2001)The objective of a motion system, when used in conjunction with a visual system, is to stimulate the pilot so that he can perceive the required motion cues necessary to fly the simulator within the same performance and ...
