“…A more distributed and body-immersive wind environment created using the Wind Cubes [20], blow displays [21], and more recently a virtual sailing environment [22] involve use of fans in proximity to the user that add wind sensation but intrude on the environment due to visible and audible fan locations. In [23], a localized VR display that uses permeable screens and a fan arrangement that is directly behind the screens is used.…”

This paper presents the Treadport Active Wind Tunnel (TPAWT)-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. The goal is to simulate the experience of realistic wind while walking in an outdoor virtual environment. A recirculating-type wind tunnel was created around the pre-existing Treadport installation by adding a large fan, ducting, and enclosure walls. Two sheets of air in a non-intrusive design flow along the side screens of the back-projection CAVE-like visual display, where they impinge and mix at the front screen to redirect towards the user in a full-body cross-section. By varying the flow conditions of the air sheets, the direction and speed of wind at the user are controlled. Design challenges to fit the wind tunnel in the pre-existing facility, and to manage turbulence to achieve stable and steerable flow, were overcome. The controller performance for wind speed and direction is demonstrated experimentally.

“…As a first illustration for how they might be used to support interfaces designed by others, leveraging some of the scaling properties of our blade-based approach, we briefly describe how the Blow Displays by Minakuchi et al [14], and Murmur by Rydarowski et al [17] could be implemented using blades and tiles. As built by Minakuchi et al, the Blow Display uses two fans driven by a Phidgets Motor Controller to divert user attention towards a PC monitor.…”

This paper presents our research toward the design and development of a library of electronic hardware modules called Blades and Tiles. Interaction hardware design with blades and tiles provides researchers with considerable flexibility in iterating their designs, decoupling between the domains of electronics, software, firmware and mechanical design. Our approach has been driven by design objectives including hardware reusability, reliability, scalability, and flexibility.We have created a library of blades and tiles, and used them to develop several interaction devices. We present both conceptual and applied aspects and discuss future directions.

“…There exist various non-contact thermal feedback [6,9]. Cold cues is less studied as fans are more generally used to simulate wind than cold [10][11][12]. Contact thermal stimulations are also expanding [5,[13][14].…”

Thanks to the digital revolution, virtual reality (VR) has getting popularity due to its capacity to immerse users into virtual environments (VEs). VEs are typically limited to visual and auditory cues; however, recent results show that multiple sensory modalities increase the user’s immersion. In this study, an experimental protocol is proposed to recreate multiple tactile, in particular thermal, sensations in VR. The aim is twofold: (1) studying the performance of different devices for creating warm and cold sensations with regards to their efficiency and acoustic disturbance; and (2) investigating the interdependency between visual and tactile stimuli in the perception of temperature. 14 participants performed two experimental studies. Our results show no acoustic disturbance of the materials used. Spot projector is more efficient than fan heater to create a warm sensation; fan + water spray is more efficient than fan alone to create cold sensation. Moreover, no significant contribution of visual cue on the thermal perception was found except for the extremely cold simulation (snow visualization and thermal stimulation performed with fan + water spray).
