“…A solenoid inside the stylus applies a braking force to the ball for friction rendering. A similar approach using a wearable vibrotactile ring has been presented in [1,21]. Minamizawa et al [23] increased the perceived weight of tangible objects using skin stretch stimuli provided by a wearable device.…”

This paper studies the combination of tangible objects and wearable haptics for improving the display of stiffness sensations in virtual environments. Tangible objects enable to feel the general shape of objects, but they are often passive or unable to simulate several varying mechanical properties. Wearable haptic devices are portable and unobtrusive interfaces able to generate varying tactile sensations, but they often fail at providing convincing stiff contacts and distributed shape sensations. We propose to combine these two approaches in virtual and augmented reality (VR/AR), becoming able of arbitrarily augmenting the perceived stiffness of real/tangible objects by providing timely tactile stimuli at the fingers. We developed a proof-of-concept enabling to simulate varying elasticity/stiffness sensations when interacting with tangible objects by using wearable tactile modules at the fingertips. We carried out a user study showing that wearable haptic stimulation can well alter the perceived stiffness of real objects, even when the tactile stimuli is not delivered at the contact point. We illustrated our approach both in VR and AR, within several use cases and different tangible settings, such as when touching surfaces, pressing buttons and pistons, or holding an object. Taken together, our results pave the way for novel haptic sensations in VR/AR by better exploiting the multiple ways of providing simple, unobtrusive, and low-cost haptic displays.

“…This effect exploits the differential sensitivity of the skin to vibrations of different frequencies. Natural haptic experiences can also be modified by processing signals felt by the skin in real time [79,80], for modifying perceived surface properties, or potentially aiding sensory loss. By adding vibrotactile feedback to a telerobotic surgery system, tactile information of textures can be transmitted and perceived by the operator [81], which can save the manipulating force for the surgeon [82] and even improve their palpation performance [83].…”

Through my entire PhD study, I learned a lot from my colleagues in the RE Touch Lab. Discussions with Gregory Reardon about technical problems, like in physics or statistics, are always constructive and inspiring. Shantonu Biswas and Thanh Nho Do influenced me with their expertise in nanoengineering and material science. Also, I am lucky to have many supportive colleagues and friends in the lab. Anzu Kawazoe can always cheer me up with her lighthearted mood, unveiling the optimistic side of life to me. Zach Wells and Harald Schafer, beside research collaborations, brought me a lot of fun outside the lab, directing me to the ocean around Santa Barbara. I also very enjoyed the company of Yufei Hao, Taku Hachisu, Simone Fani, Jasper van der Lagemaat and Behnam Khojasteh during their visit to my lab. Starting from the time I joined the lab in Philadelphia, I have been gaining support from Marco Janko and Bin Li. I am really v grateful to have all of them as my colleagues. My friends outside the lab also helped me passing through the challenging paths toward the finish line of my PhD. I want to give special thanks to Mingwei Tang, my friend since childhood, who also obtained a PhD degree in the US. We traveled together to many sights and cities. Those trips reduced my anxiety and rebuilt my courage to march forward. I also value the friendship with Yan Kong and Zhenyu Yang, who provided me after-work entertainment in Harold Frank hall, and emotional support. I miss and appreciate the time with Pingge Jiang, Lei Song, Tao Sun, Yaou Zhou and Yanan Yang during my study in Philadelphia.I appreciate the love, care and support from my girlfriend, Huihui Zhang, during the last two years of my PhD. A delightful, sweet talk with her can always relieve my stress and hearten me, motivating me to look beyond the difficulties.Finally, I like to thank my family, especially my grandmother. I grew up bathing in her unconditional love. She was always proud of me and had the strongest belief in me, from preschool till PhD, granting me the faith to overcome any challenges. I deeply regret not being able to spend enough time with her at home.

Touch interactions are central to many human activities, but there are few technologies for computationally augmenting free-hand interactions with real environments. Here, we describe Tactile Echoes, a finger-wearable system for augmenting touch interactions with physical objects. This system captures and processes touch-elicited vibrations in real-time in order to enliven tactile experiences. We process these signals via a parametric signal processing network in order to generate responsive tactile and auditory feedback. Just as acoustic echoes are produced through the delayed replication and modification of sounds, so are Tactile Echoes produced through transformations of vibrotactile inputs in the skin. The echoes also reflect the contact interactions and touched objects involved. A transient tap produces discrete echoes, while a continuous slide yields sustained feedback. We also demonstrate computational and spatial tracking methods that allow these effects to be selectively assigned to different objects or actions. A large variety of distinct multisensory effects can be designed via ten processing parameters. We investigated how Tactile Echoes are perceived in several perceptual experiments using multidimensional scaling methods. This allowed us to deduce low-dimensional, semantically grounded perceptual descriptions. We present several virtual and augmented reality applications of Tactile Echoes. In a user study, we found that these effects made interactions more responsive and engaging. Our findings show how to endow a large variety of touch interactions with expressive multisensory effects.
