This research focuses on development of a haptic system to create controlled air flow acting on a user in the Treadport virtual environment. The Treadport active wind tunnel (TPAWT) is thus created in order to produce air flow patterns that allow a variety of wind angles and speeds to be felt by the user. In order to control this system in real-time, the small gain theorem is used in conjunction with a dynamic extension to formulate an output feedback control law. Examples of controller… 
Wind display device for locomotion interface in a virtual environment
TLDR
Development of the full scale TPAWT system is described, which requires consideration of system geometry, integration, packaging, wind loads, and instrumentation.
Combined wind speed and angle control in a virtual environment using a static observer
TLDR
A static observer for estimating wind speed is developed and previously used speed and angle controllers based upon the small gain theorem with a dynamic extension and conditional angular rate-switching control are combined to simultaneously control wind speed and headwind angle.
Steady headwind display with conditional angular rate-switching control
TLDR
Key to this research is the addition of a negative pressure plenum at the rear of the treadport to improve nominal flow stability and reduce wind angle error by 75% compared to previous work.
A Full Body Steerable Wind Display for a Locomotion Interface
TLDR
A full-body immersive virtual environment for the Treadport locomotion interface designed for generating wind on a user from any frontal direction at speeds up to 20 kph to simulate the experience of realistic wind while walking in an outdoor virtual environment.
Design, Sensing, and Control of a Scaled Wind Tunnel for Atmospheric Display
Creating wind within virtual environments (e.g., wind display) is a challenging problem with a potential to develop immersive atmospheric display for virtual reality systems. This paper describes
VacuumTouch: attractive force feedback interface for haptic interactive surface using air suction
TLDR
The quantitative evaluation was conducted with the suction dial and showed that the attractive force provided by VacuumTouch improved the performance of the dial menu interface and its potential effects.
Integrating Particle Dispersion Models into Real-time Virtual Environments
TLDR
The goal is to develop a tool for interacting with, controlling, and manipulating the model parameters of fast response particle dispersion systems while immersed within the simulation environment.
WindyWall: Exploring Creative Wind Simulations
TLDR
A pilot study of wind magnitude perception using different wind activation patterns from WindyWall suggests horizontal wind activations are perceived more readily than vertical ones, and that people's perceptions of wind are highly variable-most individuals will rate airflow differently in subsequent exposures.
A novel wearable device to present localized sensation of wind
TLDR
This paper evaluated the sensation threshold of wind at different parts of the body, focusing on the head, and measured the two-point discrimination threshold of the most sensitive area on theHead, which is around the ears.
Multi-sensorial field display: Presenting spatial distribution of airflow and odor
TLDR
The preliminary sensory tests are presented to show the potential of the MSF display, which can present the airflow blowing from the front to the user without placing fans in front of the user.

TLDR
This work presents numerical results that suggest that for boundary control of the 2D heat equation, the functional gains exist and have compact support near the boundary where the control is applied and uses these results to guide the placement of discrete sensors and compare the results to full state feedback.
