“…Ilkhani et al [20] propose a texture rendering algorithm to reproduce the acceleration signal on the haptic display, and a comparison is conducted between simulated feeling and real objects. Zhao et al [21] combines the acceleration signals and friction properties to improve the realism of the haptic rendering.…”

“…Then we reproduced such recorded sounds and vibrations, either separately or together, respectively through headphones and on a hard glass plate actuated by a vibrotactile transducer. The tactile display avoided surface texture rendering technologies [11,60]. For its simplicity and low cost [10], this setup is ideal for testing the audio-tactile feedback of virtual buttons on touchscreens specific for operating large catering appliances, goal of this research.…”

Two experiments studied the role of impact sounds and vibrations in classification of materials. The task consisted of feeling on an actuated surface and listening through headphones to the recorded feedback of a ping-pong ball hitting three flat objects respectively made of wood, plastic, and metal, and then identifying their material. In Experiment 1, sounds and vibrations were recorded by keeping the objects in mechanical isolation. In Experiment 2, recordings were taken while the same objects stood on a table, causing their resonances to fade faster due to mechanical coupling with the support. A control experiment, where participants listened to and touched the real objects in mechanical isolation, showed high accuracy of classification from either sounds (90% correct) or vibrations (67% correct). Classification of reproduced bounces in Experiments 1 and 2 was less precise. In both experiments, the main effect of material was statistically significant; conversely, the main effect of modality (auditory or tactile) was significant only in the control. Identification of plastic and especially metal was less accurate in Experiment 2, suggesting that participants, when possible, classified materials by longer resonance tails. Audio-tactile summation of classification accuracy was found, suggesting that multisensory integration influences the perception of materials. Such results have prospective application to the nonvisual design of virtual buttons, which is the object of our current research.

Haptic feedback, a natural component of our everyday interactions in the physical world, requires careful design in virtual environments. However, feedback location can vary from the fingertip to the finger, hand, and arm due to heterogeneous input/output technology used for virtual environments, from joysticks to controllers, gloves, armbands, and vests. In this work, we report on the user experience of touch interaction with virtual displays when vibrotactile feedback is delivered on the finger, wrist, and forearm. In a first controlled experiment with fourteen participants and virtual displays rendered through a head-mounted device, we report a user experience characterized by high perceived enjoyment, confidence, efficiency, and integration as well as low perceived distraction, difficulty, and confusion. Moreover, we highlight participants’ preferences for vibrotactile feedback on the finger compared to other locations on the arm or through the VR controller, respectively. In a follow-up experiment with fourteen new participants and physical touchscreens, we report a similar preference for the finger, but also specific nuances of the self-reported experience, not observed in the first experiment with virtual displays. Overall, our results depict an enhanced user experience when distal vibrotactile feedback is available over no vibrations at all during interactions with virtual and physical displays, for which we propose future work opportunities for augmented interactions in virtual worlds.
