Haptic interfaces play a crucial role in enriching human collaboration and interaction with artificial systems. The pursuit of realism and immersion has motivated researchers to develop technologies that deliver cutaneous and kinesthetic cues in a natural and effective manner. This technological advancement has been accompanied by a deepening understanding of the neurophysiological aspects of human touch, as novel haptic devices offer the dual opportunity to advance both technology and scientific knowledge. On one front, there is a demand for interfaces with improved wearability, ergonomics, and intuitiveness, driving the prototyping of new actuation and sensing systems such as pneumatic, textile, and shape-memory alloys, alongside the adoption of innovative materials and mechanical structures including soft materials and origami-inspired designs. Simultaneously, numerous high-fidelity, reliable, and accurate devices have been developed specifically to facilitate the study of human perception and discrimination of haptic stimuli within the context of human-robot interaction.
This workshop stems from the recognition that haptic technologies hold great potential for enhancing collaboration between humans and artificial systems. With the proliferation of collaborative robots and AI-based assistants, there is an opportunity to leverage haptic interfaces to establish new paradigms of human-robot (physical) communication, beyond standard audiovisual means. Drawing inspiration from human-to-human communication, this workshop aims to explore how haptic technologies can be integrated into human-robot and human-avatar interaction to foster a dual-level connection encompassing both emotional and informational aspects. Haptics, traditionally associated with mere force rendering in robotic teleoperation, now emerges as a pivotal tool for enabling robots to convey task-related information while fostering an emotional rapport with human collaborators.
