Abstract

Realistic actuation of social touch remains a pressing challenge. This study evaluated a shape-memory alloy (SMA) based arm-sleeve, which actuated touch patterns in the range of C-tactile optimal velocity (3 to 4.5 cm/s) that is known to evoke pleasant affect. We manipulated the intensity (238, 289 & 340 mA) and overlap (0, 187 & 375 ms) of the actuation. Twenty-one participants rated the perceived continuity and intensity of the resulting stroking and tapping patterns. Their psychophysiological reactions of pleasantness derived from activities of the zygomaticus major muscle were also measured by facial electromyography (EMG). At the highest actuation intensity (340 mA), greater differences in perceived continuity between conditions of actuation overlaps were observed (p < .001), with the highest continuity rating for an overlap of 375 ms. Relative to other conditions, this parameter combination elicited higher facial muscle activities of positive affect (p < .001). Crucially, individual differences in perceived continuity and psychophysiological reactions of positive affect correlated positively. These findings (i) extend evidence of pleasant responses elicited by human touch and touch by haptic actuators and (ii) establish a psychophysiologically based perceptual benchmark for designing haptic devices to render affective touch.

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
