“…The delivery of tactile feedback in telepresence operations is fundamental to augment users' immersivity; examples can be found in minimally invasive surgery [6] and in industrial operations [3,[20][21][22] and manufacturing [23]. In this context, where robots are mainly involved in object manipulation tasks, tactile feedback can help in performing high-precision activities keeping the human operator in the loop.…”

Research on bidirectional human-machine interfaces will enable the smooth interaction with robotic platforms in contexts ranging from industry to tele-medicine and rescue. This paper introduces a bidirectional communication system to achieve multisensory telepresence during the gestural control of an industrial robotic arm. We complement the gesture-based control by means of a tactile-feedback strategy grounding on a spiking artificial neuron model. Force and motion from the robot are converted in neuromorphic haptic stimuli delivered on the user’s hand through a vibro-tactile glove. Untrained personnel participated in an experimental task benchmarking a pick-and-place operation. The robot end-effector was used to sequentially press six buttons, illuminated according to a random sequence, and comparing the tasks executed without and with tactile feedback. The results demonstrated the reliability of the hand tracking strategy developed for controlling the robotic arm, and the effectiveness of a neuronal spiking model for encoding hand displacement and exerted forces in order to promote a fluid embodiment of the haptic interface and control strategy. The main contribution of this paper is in presenting a robotic arm under gesture-based remote control with multisensory telepresence, demonstrating for the first time that a spiking haptic interface can be used to effectively deliver on the skin surface a sequence of stimuli emulating the neural code of the mechanoreceptors beneath.

“…• Meissner's corpuscles: high spatial resolution, fast adaption rate, located in the glabrous skin (fingers, lips) [10]. The information gathered by the receptors is transferred to the brain via the fastest communication channel in the human body: the dorsal lateral column way, where the information travels at the speed of 100 m/s.…”

Abstract-This paper investigates intuitiveness in human robot interactions with focus on remote operation and assistance. The increasing number of robot applications in small volume production requires new techniques to ease the use of these sophisticated systems. A vibrotactile device was used for experiments. Vibration patterns are developed to represent a cognitive information channel for the remote operator. Most of the patterns are based on natural sensations, e.g. the feedback of gripping an object is slight vibration on the index finger and the thumb. Usability test results are presented. Intuitiveness of the vibrotactile feedback is confirmed in remote operation but the solution can be used in shop floor situations as well.

“…Meanwhile, the sound stream was analysed and encoded into vibrotactile stimuli. More and more reports on vibrotactile display systems have shown their potential application in various domains, including information display, rehabilitation applications, gaming and entertainment in virtual environments [10][11][12][13][14].…”

A vibrotactile array is a promising human computer interface which could display graphical information to users in a tactile form. This paper presents the design and testing of an image contour display system with a vibrotactile array. The tactile image display system is attached to the back of the user. It converts visual graphics into 2D tactile images and allows subjects to feel the contours of objects through vibration stimulus. The system consists of a USB camera, 48 (6×8) vibrating motors and an embedded control system. The image is captured by the camera and the 2D contour is extracted and transformed into vibrotactile stimuli using a temporalspatial dynamic coding method. Preliminary experiments were carried out and the optimal parameters of the vibrating time and duration were explored. To evaluate the feasibility and robustness of this vibration mode, letters were also tactilely displayed and the recognition rate about the alphabet letter display was investigated. It was shown that under the condition of no pre-training for the subjects, the recognition rate was 82%. Such a recognition rate is higher than that of the scanning mode (47.5%) and the improved handwriting mode (76.8%). The results indicated that the proposed method was efficient in conveying the contour information to the visually impaired by means of vibrations.
