With increasing use of computer applications and robotic devices in our everyday life, and with the advent of metaverse, there is an urgent need of developing new types of interfaces that facilitate a more intuitive interaction in physical and virtual space. In this work, we investigate the influence of the location of haptic feedback devices on embodiment of virtual hands and user load during an interactive pick-and-place task. To do this, we conducted a user study with a 3x2 repeated measure experiment design: feedback position is varied between the distal phalanx of the index finger and the thumb, the proximal phalanx of the index finger and the thumb, and the wrist. These conditions of feedback are tested with the stimuli applied synchronously to the participant in one case, and with an additional delay of 350 ms in the second case. The results show that the location of the haptic feedback device does not affect embodiment, whereas the delay, i.e., whether the feedback is applied synchronously or asynchronously, affects embodiment. This suggests that for pick-and-place tasks, haptic feedback devices can be placed on the user's wrist without compromising performance making the hands to remain free, allowing unobstructed hand visibility for precise motion tracking, thereby improving accuracy.

In this brief, we present the preliminary design of a wearable system able to detect and haptically display head motions of conversation participants. The aim of the system is to allow for remote communication to not have to rely on visual social cues. To demonstrate the design principles of the system, we recorded data from a single participant during a remote walking conversation using Zoom.

This workshop aims to generate an interdisciplinary research agenda for digital touch communication that effectively integrates technological progress with robust investigations of the social nature and significance of digital touch. State-of-the-art touch-based technologies have the potential to supplement, extend or reconfigure how people communicate through reshaping existing touch practices and generating new capacities. Their possible impact on interpersonal intimacy, wellbeing, cultural norms, ways of knowing and power relations is far-reaching and under-researched. Few emerging devices and applications are embedded into everyday touch practices, limiting empirical exploration of the implications of digital touch technologies in everyday communication. There is, thus, a real need for methodological innovation and interdisciplinary collaboration to critically examine digital touch communication across social contexts and technological domains, to better understand the social consequences of how touch is digitally remediated. This agenda-setting workshop will bring together HCI researchers and designers with colleagues from sociology, media & communications, arts & design to address key research challenges and build the foundations for future collaborations.
