“…Another issue is that while thermal wind enriches the VR experience [12], the devices that provide hot and cool winds tend to be large. This is because constantly changing the air temperature from room temperature to the target temperature while providing a hot or cold wind requires enormous heat exchange.…”

Numerous wind displays have been developed to provide wind sensation in virtual reality applications. However, in previous studies, wind displays required the production of physical wind using a wind source. To release cold or hot wind, previous wind displays required large equipment for making the air temperature changes. In this study, we propose to induce pseudo-wind perception, perceiving wind even in the absence of physical wind, using visuo-audio-haptic cross-modal effects. We provide audio-visual stimuli with a head-mounted display and headphones, and vibrotactile and thermal stimuli to the skin using belt-type devices, instead of physical wind. We found that vibrotactile and thermal stimuli based on the measurement of skin displacement and temperature exposed to the wind are suitable for the tactile sensation of wind. We also found that thermal and audio-visual stimuli can induce wind sensation of cold wind, and that vibro-thermal stimuli in addition to audio-visual stimuli are effective for the wind sensation and realness of the experience of hot wind. In future, inducing variable types of wind sensations will be pursued as a research direction regarding pseudo-wind perception.

“…Twirl allows for the exploration of how thermal and wind stimuli can be combined to enhance the user experience, how people experience the magnitude of hot and cold airflows or how to design effective cold and wind simulations in a variety of applications -cold airflows as a rolling breeze on the user's face while interacting with a game that simulates a snowboarding experience; hot airflows in a simulated steel factory environment for industrial training; a puff of air embodying a message such as a cue or a notification, etc. Herein, we build upon the work of Rodrigues et al [21] with new experiments and insights, and substantial details, including: (i) an extended related work section, (ii) budgeting for the system, (iii) a new assessment on temperature variations as a function of distance, (iv) an acceptance and uptake survey based on user experience, VR hardware acceptance model, temple presence inventory, and the technology's application, and (iv) an in-depth discussion of the findings and the future perspectives they have spawned.…”

In this paper, we introduce Twirl, a haptic system that allows the creation and delivery of hot and cold airflow synchronised with audiovisual content. Twirl combines vaporization of cooled water by Peltier elements for cold wind and hair dryers for warm wind steered by wind fans. To assess our system, we conducted several studies. First, we analyzed the time our devices take to deliver these effects considering different starting temperatures in the environment. Then, we annotated three videos with hot wind, cold wind, and both effects respectively to observe the feasibility of having those effects integrated with audiovisual content. Next, we assessed the temperature variation of the devices as a function of distance. Finally, we distributed questionnaires such as Virtual Reality Hardware Acceptance Model and Lombard's Temple Presence Inventory questionnaires to assess different user experience facets and attitudes towards the proposed device. Preliminary results highlighted positive user attitudes and experiences towards Twirl.

“…Although this work is not a systematic review in the sense of having a strict methodology for the selection and separation of studies, it can be classified as a overview [16] and the articles highlighted therein were identified as being relevant towards the development of a haptic device that deals with the emission of hot and cold air flows [46]. These studies were found in Google Scholar, terms for searching were: "Mulsemedia", "Human-Computer Interaction", "Quality of Experience", "Thermal Sensation", "Multisensory", "Immersive Environment", "Immersive Experience".…”

In order to create immersive experiences in virtual worlds, we need to explore different human senses (sight, hearing, smell, taste, and touch). Many different devices have been developed by both industry and academia towards this aim. In this paper, we focus our attention on the researched area of thermal and wind devices to deliver the sensations of heat and cold against people’s skin and their application to human-computer interaction (HCI). First, we present a review of devices and their features that were identified as relevant. Then, we highlight the users’ experience with thermal and wind devices, highlighting limitations either found or inferred by the authors and studies selected for this survey. Accordingly, from the current literature, we can infer that, in wind and temperature-based haptic systems (i) users experience wind effects produced by fans that move air molecules at room temperature, and (ii) there is no integration of thermal components to devices intended for the production of both cold or hot airflows. Subsequently, an analysis of why thermal wind devices have not been devised yet is undertaken, highlighting the challenges of creating such devices.
