“…However, reinforcing user’s senses is challenging. Jeong et al developed a thermal stimulation device using Peltier elements worn on the wrist and on the back of the neck as a messaging tool [ 23 ]. Yamazaki et al proposed a neck-worn haptic device that can dynamically modulate the amplitude, phase, and frequency of vibration, and they conducted experiments using only haptic information to reach an invisible image [ 24 ].…”

Recently, remote meetings and work-from-home have become more common, reducing the opportunities for face-to-face communication. To facilitate communication among remote workers, researchers have focused on virtual space technology and spatial augmented reality technology. Although these technologies can enhance immersiveness in collaborative work, they face the challenge of fostering a sense of physical contact. In this work, we aimed to foster a sense of presence through haptic stimulation using pneumatic actuators. Specifically, we developed a choker-type wearable device that presents various pressure patterns around the neck; the pattern presented depends on the message the device must convey. Various combinations of haptic presentation are achieved by pumping air to the multiple pneumatic actuators attached to the choker. In addition, we conducted experiments involving actuators of different shapes to optimize the haptic presentation. When linked with a smartphone, the proposed device can present pressure patterns to indicate incoming calls and notifications, to give warning about an obstacle that one who is texting might miss while walking, and to provide direction to a pedestrian. Furthermore, the device can be used in a wide range of applications, from those necessary in daily living to those that enhance one’s experience in the realm of entertainment. For example, haptic feedback that synchronizes with the presence of a singer or with the rhythm of a song one listens to or with a performer’s movements during a stage performance will immerse users in an enjoyable experience.

“…Similarly, Peng et al [27] explored the sensation of "passing through" with different thermal stimuli with two modules placed on the top and the bottom of the wrist. Following this trend while Jeong et al [18] explored thermal haptic cues with four modules around the wrist, ThermalBracelet [26] explored thermal haptic feedback around the users' wrist mainly to deliver notifications as an alternative to the vibrotactile based methods.…”

This paper presents THED, a wearable thermal display to perceive spatial thermal sensations within a virtual reality (VR) environment. THED consists of a wrist-worn thermal stimulation module and a control module utilizing Bluetooth TM communication to connect with the VR environment. To demonstrate THED, we have developed a VR environment showing a virtual campfire in a snowy climate where participants were able to experience the virtual campfire in different predetermined distances. We have conducted a user experiment to 1) determine the distance based perception of spatial thermal sensations in a VR setting (VR only), 2) determine the differences of thermal stimuli on participants' wrists (thermal only), and 3) evaluate the effects of combined thermal stimuli towards their expected spatial thermal stimuli (VR + thermal). Our primary aim of this study is to learn how humans spatially perceive thermal sensations on their hands (utilizing only one hand vs. both hands) when given a wrist-worn thermal source coupled with a virtual reality scenario. Our findings show that different thermal stimuli utilized by THED were able to provide thermal sensations in virtual reality that closely mirrored participants' expected thermal sensations in respective real world scenarios.
