The exciting new technology known as mid-air haptics has been adopted by several industries including Automotive and Entertainment, however it has yet to emerge in simulated pilot training or in real-life flight decks. Full-flight simulators are expensive to manufacture, maintain and operate. Not only that, each simulator is limited to one aircraft type, which is inefficient for the majority of airlines that have several in service. With the growing trend in touchscreen instrumentation, cockpit displays require the pilot's attention to be drawn away from their view out of the window. But by using gesture recognition interfaces combined with mid-air haptic feedback, we can mitigate this shortcoming while also adding another dimension to the existing technology for pilots already familiar with using legacy cockpits, complete with traditional instrumentation. Meanwhile, simulation environments using augmented and virtual reality technology offers quality immersive training to the extent that pilots can go from hundreds of hours of simulated training to being responsible for hundreds of lives on their very first flight. The software re-programmability and dynamic richness afforded by mid-air haptic technologies combined with a basic full-motion platform could allow for an interchange of instrumentation layouts thus enhancing simulation immersiveness and environments. Finally, by borrowing and exploring concepts within the automotive sector, this concept paper presents how flight deck design could evolve by adopting this technology. If pilot testimony suggests that they can adapt to virtual objects, can this replace physical controls?
Previous studies have aimed at creating a simple hardware implementation of surface friction display. In this study, we propose a new method for presenting static frictional sensation using the pseudo-haptic effect as a first attempt, which is the simplest implementation of presenting static friction sensation. We focus on the stick-slip phenomenon while users explore surfaces with an input device, such as a stylus. During the stick phase, we present users with pseudo-haptic feedback that represents static friction on the surface. In our method, users watch a virtual contact point become stuck…

A continuous stroking sensation on the skin can convey messages or emotion cues. We seek to induce this sensation using a combination of illusory motion and lateral stroking via a haptic device. Our system provides discrete lateral skin-slip on the forearm with rotating tactors, which independently provide lateral skin-slip in a timed sequence. We vary the sensation by changing the angular velocity and delay between adjacent tactors, such that the apparent speed of the perceived stroke ranges from 2.5 to 48.2 cm/s. We investigated which actuation parameters create the most pleasant and continu…
In this research, we have developed a haptic situational awareness device that presents users with directional cues through continuous vibrotactile sensations. Using the device, we present user studies on the effectiveness of a torso-mounted haptic display in enhancing human situational awareness, when visual/auditory senses are degraded. A haptic display has been developed which generates continuous cues using tactile illusions and programmed to generate navigation commands. Participants are given navigation tasks where they may receive commands through any of the seven sensory modality combi…

A common and effective form of social touch is stroking on the forearm. We seek to replicate this stroking sensation using haptic illusions. This work compares two methods that provide sequential discrete stimulation: sequential normal indentation and sequential lateral skin-slip using discrete actuators. Our goals are to understand which form of stimulation more effectively creates a continuous stroking sensation, and how many discrete contact points are needed. We performed a study with 20 participants in which they rated sensations from the haptic devices on continuity and pleasantness. We …
In a typical mid-air haptics system, focused airborne ultrasound provides vibrotactile sensations to localized areas on a bare skin. Herein, a method for displaying thermal sensations to hands where mesh fabric gloves are worn is proposed. The gloves employed in this study are commercially available mesh fabric gloves with sound absorption characteristics, such as cotton work gloves without any additional devices such as Peltier elements. The method proposed in this study can also provide vibrotactile sensations by changing the ultrasonic irradiation pattern. In this paper, we report basic exp…
Grounded haptic devices can provide a variety of forces but have limited working volumes. Wearable haptic devices operate over a large volume but are relatively restricted in the types of stimuli they can generate. We propose the concept of docking haptics, in which different types of haptic devices are dynamically docked at run time. This creates a hybrid system, where the potential feedback depends on the user's location. We show a prototype docking haptic workspace, combining a grounded six degree-of-freedom force feedback arm with a hand exoskeleton. We are able to create the sensation of …
The simulation of tactile sensation using haptic devices is increasingly investigated in conjunction with simulation and training. In this paper we explore the most popular haptic frameworks and APIs. We provide a comprehensive review and comparison of their features and capabilities, from the perspective of the need to develop a haptic simulator for medical training purposes. In order to compare the studied frameworks and APIs, we identified and applied a set of 11 criteria and we obtained a classification of platforms, from the perspective of our project. According to this classification, we…
Touch is the first sense among human senses. Not only that, but it is also one of the most important senses that are indispensable. However, compared to sight and hearing, it is often neglected. In particular, since humans use the tactile sense of the skin to recognize and manipulate objects, without tactile sensation, it is very difficult to recognize or skillfully manipulate objects. In addition, the importance and interest of haptic technology related to touch are increasing with the development of technologies such as VR and AR in recent years. So far, the focus is only on haptic technolog…
Noninvasive brain-computer interface (BCI) is widely used to recognize users' intentions. Especially, BCI related to tactile and sensation decoding could provide various effects on many industrial fields such as manufacturing advanced touch displays, controlling robotic devices, and more immersive virtual reality or augmented reality. In this paper, we introduce haptic and sensory perception-based BCI systems called neurohaptics. It is a preliminary study for a variety of scenarios using actual touch and touch imagery paradigms. We designed a novel experimental environment and a device that co…
