Hattum, M.T. (author), Huisman, G. (author), Toet, A. (author), van Erp, J.B.F. (author)In recent years, there has been a significant increase in research on mediated communication via social touch. Previous studies indicated that mediated social touch (MST) can induce similar positive outcomes to interpersonal touch. However, studies investigating the user experience of MST technology predominantly involve brief experiments that...article 2022

(author)Effective haptic feedback in virtual reality (VR) is an essential element for creating convincing immersive experiences. To design such feedback, state-of-the-art VR setups provide APIs for programmatically generating controller vibration patterns. While tools for designing vibrotactile feedback keep evolving, they often require expert knowledge...conference paper 2021

(author)Social VR shall allow natural communication between users with high social presence, as if users are in the same room. One way to increase social presence is to add haptic interaction to allow,for example, users to give each other a "high-five" or to pass documents among them. In this paper, we present our web-based VR communication framework...conference paper 2020

Neural representations of haptic object size in the human brain revealed by multivoxel fMRI patternsPerini, F. (author), Powell, T. (author), Watt, S.J. (author), Downing, P.E. (author)The brain must interpret sensory input from diverse receptor systems to estimate object properties. Much has been learned about the brain mechanisms behind these processes in vision, but our understanding of haptic perception remains less clear. Here we examined haptic judgments of object size, which require integrating multiple cutaneous and...article 2020

Kuling, I.A. (author), Gijsbertse, K. (author), Krom, B.N. (author), van Teeffelen, K.J. (author), van Erp, J.B.F. (author)Haptic feedback is a desired feature in teleoperation as it can improve dexterous manipulation. Direct force feedback to the operator’s hand and fingers requires complex hardware and therefore substituting force by for instance vibration is a relevant topic. In this experiment, we tested performance on a Box & Blocks task in a teleoperation set...conference paper 2020

(author), Gelinck, G.H. (author)Ultrasound based mid-air haptic feedback devices can produce tactile sensations at any time and position without restricting human motion. This is useful for augmented and virtual reality, feedback buttons and virtual user interfaces. The haptic feedback mechanism is caused by acoustic radiation force and streaming. Typical solutions to induce...conference paper 2020

(author)Recently, there has been considerable interest in the development of ultrasound based mid-air haptic feedback devices. These devices allow for tactile sensations to be induced at any position and time without constraints to human motion, which is useful for virtual user interfaces, augmented/virtual reality and feedback buttons.

Catoire, M. (author), Krom, B.N. (author), van Erp, J.B.F. (author)A high level of dexterity is becoming increasingly important for teleoperated inspection, maintenance and repair robots. A standard test to benchmark system dexterity can advance the design, quantify possible improvements, and increase the effectiveness of such systems. Because of the wide variety of tasks and application domains ranging from...conference paper 2018

Fu, W. (author), Landman, H.M. (author), van Paassen, M.M. (author), Mulder, M. (author)We discuss an extension of the basic principles underlying the human haptic just noticeable difference (JND) in perceiving a manipulator's mechanical properties from force feedback. Two cases are studied: 1) the JND in perceiving the stiffness of manipulators with various masses; 2) the JND in perceiving the damping of a combined mass-spring...article 2018

Willemse, C.J.A.M. (author), Heylen, D.K.J. (author), van Erp, J.B.F. (author)Affective haptic interfaces are designed to influence one’s emotional and physiological state via the sense of touch, and may be applied as communication media to increase the sense of closeness. Recent research suggests that stimulation with physical warmth can enhance this interpersonal closeness: a physical-social warmth link. It is often...article 2018

Willemse, C.J.A.M. (author), Toet, A. (author), van Erp, J.B.F. (author)Social touch forms an important aspect of the human non-verbal communication repertoire, but is often overlooked in human–robot interaction. In this study, we investigated whether robot-initiated touches can induce physiological, emotional, and behavioral responses similar to those reported for human touches. Thirty-nine participants were...article 2017
