“…Harrington et al [9] and Shakeri et al [10] demonstrated the use of ultrasound haptics in vehicular applications, showing significant reductions in visual demand, interaction times, and improved accuracy. Finally, Georgiou et al [11] used ultrasound haptics for a VR mid-air haptic rhythm game, and Martinez et al [12] for an immersive fantasy narrative.…”

Mid-air haptics technologies are able to convey haptic sensations without any direct contact between the user and the haptic interface. One representative example of this technology is ultrasound haptics, which uses ultrasonic phased arrays to deliver haptic sensations. Research on ultrasound haptics is only in its beginnings, and the literature still lacks principled perception studies in this domain. This paper presents a series of human subject experiments investigating important perceptual aspects related to the rendering of 2D shapes by an ultrasound haptic interface (the Ultrahaptics STRATOS platform). We carried out four user studies aiming at evaluating (i) the absolute detection threshold for a static focal point rendered via amplitude modulation, (ii) the absolute detection and identification thresholds for line patterns rendered via spatiotemporal modulation, (iii) the ability to discriminate different line orientations, and (iv) the ability to perceive virtual bumps and holes. These results shed light on the rendering capabilities and limitations of this novel technology for 2D shapes.

“…By tuning parameters, such as the location of the mid-air haptic stimulus, number of haptic points, modulating the frequency, among other factors, it is possible to generate haptic patterns that are suitable for different applications. For example, Vi et al [22] used mid-air haptic technology to enhance the experience of visual art in a museum, Martinez et al [18] generated haptic sensations that mimic supernatural experiences in VR and in [10] buttons and sliders were augmented with mid-air haptic feedback in a driving simulator, to reduce off-road glance time. Gil et al [9] explored the perception of mid-air haptic cues on the face, across different parameters and in a practical notification task.…”

Figure 1. With HaptiRead we evaluate for the first time the possibility of presenting Braille information as touchless haptic stimulation using ultrasonic mid-air haptic technology. We present three different methods of generating the haptic stimulation: Constant, Point-by-Point and Row-by-Row. (a) depicts the standard ordering of cells in a Braille character, and (b) shows how the character in (a) is displayed by the three proposed methods. HaptiRead delivers the information directly to the user, through their palm, in an unobtrusive manner. Thus the haptic display is particularly suitable for messages communicated in public, e.g. reading the departure time of the next bus at the bus stop (c).

Martinez et al [24] proposed the contactless tactile feedback that can simultaneously interacte Leap Motion's gesture recognition with laser tactile system. They improved the immersion of system by Leap Motion's precise gesture recognition interaction and touchless tactile simulation of laser array.…”

The more sensory channels are equipped in a virtual assembly system, the more real users feel in the whole system, however, most of the existing virtual assembly systems are based on the natural interaction method of one or two sensory channels. Thus, this paper proposes a novel virtual assembly system integrating multi-sensory channels, including gesture interaction, Chinese speech interaction, tactile interaction, 3D display and real-time display of real environment pictures in the virtual environment. To improve the operability of the virtual environment, we analyze the parallel virtual assembly sequence on the basis of two-hand interaction, and the assembly priority is prompted based on UI interface. For ease of operation, we present a method of viewpoint control based on gesture interaction and the coordinate threshold of spatial position. A hierarchical bounding box collision detection algorithm based on volume difference is proposed to improve the efficiency of collision feedback and collision avoidance. In addition, the power equipment models are exhibited in the virtual scene, as the exhibits of the virtual roaming process. Finally, to evaluate the training effect of this system, a comparative experiment is designed to compare the participants' experience and the effect of assembly training. The experimental results show that the virtual assembly system of natural interaction with multi-sensory channels is flexible and immersive.
