Redirecting View Rotation in Immersive Movies with Washout Filters

2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR), 2019
Immersive movies take advantage of virtual reality (VR) to bring new opportunities for storytelling that allow users to naturally turn their heads and bodies to view a 3D virtual world and follow the story in a surrounding space. However, while many designers often assume scenarios where viewers stand and are free to physically turn without constraints,

PROTEST - An expert system for tuning simulator washout filters

Flight Simulation Technologies Conference, 1995
Current motion-drive algorithms have a number of coefficients that are selected to tune the motion of the simulator. Little attention has been given to the process of selecting the most appropriate coefficient values. Final tuning is best accomplished using experienced evaluation pilots to provide feedback to a washout filter expert who adjusts the ...

Latency on a Stewart platform using washout filter

The Aeronautical Journal, 2018
ABSTRACTThe aim of this work is to investigate and quantify the latency on a Stewart Platform caused exclusively by a Classic washout filter. This washout filter is intended to recreate the sensations of motion caused by changes of translational and rotational acceleration that an aircraft can provide, due to changes in attitudes caused by external ...

Motion Washout Filter Tuning: Rules and Requirements

Journal of Aircraft, 1997
Current motion-drive algorithms have a number of coefficients that are selected to tune the motion of the simulator. Little attention has been given to the process of selecting the most appropriate coefficient values. Final tuning is best accomplished using experienced evaluation pilots to provide feedback to a washout filter expert who adjusts the ...

Anti-control of Hopf bifurcations through washout filters

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
Bifurcation control generally means to design a controller that can modify the bifurcation characteristics of a bifurcating nonlinear system, thereby achieving some desirable dynamical behaviors. A typical objective is delay and/or stabilization of a given bifurcation.

Washout of Grains from Filtered Sand and Gravel Materials

Journal of Geotechnical Engineering, 1993
Some presently used filter criteria are illogical. Besides satisfying D15/d85≤5 and D15/d15≥4, both the base and filter materials must possess grading stability when exposed to seepage. There are two reasons for grading instability; scantiness of intermediate grain sizes, which interrupts an internal filter formation process; and loose grains, which ...

Hopf bifurcation control of lu system via washout filter

2011 Chinese Control and Decision Conference (CCDC), 2011
This paper is concerned with the hopf bifurcation control of Lu system. Firstly, the stability of the equilibriums of the system is studied, and the critical value of the system parameter at which hopf bifurcation occurs is investigated. Secondly, washout filter aided feedback controllers are designed for ensuring the stability of the bifurcated limit ...

An Optimal Washout Filter Design with Fuzzy Compensation for a Motion Platform

IFAC Proceedings Volumes, 2011
Abstract The realistic motion of the vehicular simulator is produced by the motion cueing algorithm. An optimal washout filter, taking into account the limitation of the simulator's workspace, is applied here to minimize human's perception error in order to provide realistic behavior.

Washout-filter based bifurcation control of longitudinal flight dynamics

2002 IEEE Region 10 Conference on Computers, Communications, Control and Power Engineering. TENCOM '02. Proceedings., 2003
This paper presents the bifurcation control of longitudinal flight dynamic, via washout filter based design. Based on the mathematical model proposed by Garrard and Jordial (1977). a rich variety of bifurcation phenomena, such as saddle-node bifurcation, Hopf bifurcation, and cycle fold bifurcations are observed in the numerical simulations of ...

Human Perception-Based Washout Filtering Using Genetic Algorithm

2015
The Motion Cueing Algorithm MCA transforms longitudinal and rotational motions into simulator movement, aiming to regenerate high fidelity motion within the simulators physical limitations. Classical washout filters are widely used in commercial simulators because of their relative simplicity and reasonable performance.
