This paper reports experimental research aimed to provide seamlessly moving illusory tactile sensations across a large area of the body using a few vibration actuators. The human vibrotactile sensitivity differences among the body sites are calibrated using empirically-measured psychophysical magnitude functions. We present a new phantom sensation rendering method that uses the Gaussian function emphasizing the spatial continuity of perceived movement and the temporal consistency of perceived intensity. We demonstrate that our rendering method outperforms previous methods for phantom sensations via a perceptual experiment. Our method is tailored to eliciting the perception of illusory tactile sensation moving in a long distance, from the thigh to the upper back.

Both vision and touch contribute to the perception of real surfaces. Although there have been many studies on the individual contributions of each sense, it is still unclear how each modality’s information is processed and integrated. To fill this gap, we investigated the similarity of visual and haptic perceptual spaces, as well as how well they each correlate with fingertip interaction metrics. Twenty participants interacted with ten different real surfaces from the Penn Haptic Texture Toolkit by either looking at or touching them and judged their similarity in pairs. By analyzing the resulting similarity ratings using non-metric multi-dimensional scaling (NMDS), we found that surfaces are similarly organized within the three-dimensional perceptual spaces of both modalities. Also, between-participant correlations were significantly higher in the haptic condition. In a separate experiment, we obtained the contact forces and accelerations acting on one finger interacting with each surface in a controlled way. We analyzed the collected fingertip interaction data in both the time and frequency domains. Our results suggest that the three perceptual dimensions for each modality can be represented by roughness/smoothness, hardness/softness, and friction, and that these dimensions can be estimated by surface vibration power, tap spectral centroid, and kinetic friction coefficient, respectively.

Human-to-human touch conveys rich, meaningful social and emotional sentiment. At present, however, we understand neither the physical attributes that underlie such touch, nor how the attributes evoke responses in unique types of peripheral afferents. Indeed, nearly all electrophysiological studies use well-controlled but non-ecological stimuli. Here, we develop motion tracking and algorithms to quantify physical attributes – indentation depth, shear velocity, contact area, and distance to the cutaneous sensory space (receptive field) of the afferent – underlying human-to-human touch. In particular, 2-D video of the scene is combined with 3-D stereo infrared video of the toucher’s hand to measure contact interactions local to the receptive field of the receiver’s afferent. The combined and algorithmically corrected measurements improve accuracy, especially of occluded and misidentified fingers. Human subjects experiments track a toucher performing four gestures – single finger tapping, multi-finger tapping, multi-finger stroking and whole hand holding – while action potentials are recorded from a first-order afferent of the receiver. A case study with one rapidly-adapting (Pacinian) and one C-tactile afferent examines temporal ties between gestures and elicited action potentials. The results indicate this method holds promise in determining the roles of unique afferent types in encoding social and emotional touch attributes in their naturalistic delivery.

In this study we investigated the use of simple vibrotactile signals to simulate contact with a virtual object. In particular we explored the relation between properties of the signal and the perceived hardness of the object. The space of stimuli is large, and we have no plausible a priori model for the relationship of parameters to percept. Thus we made use of non-parametric Bayesian methods, in particular utilizing Gaussian process priors. We show that this method both gives insight into the phenomenon of interest and well-predicts a second, separate data set collected via the method of constant stimuli. Thus we argue that it could be a fruitful approach for attacking a variety of perceptual problems.

Four experiments used a programmable ultrasonic friction-modulation device to explore parameters that might be candidates for roughness modulation and to assess whether spatially modulated texture gradients could be discriminated by their direction of change. Candidate roughness parameters included frequency, amplitude and two implementations of local friction variation (noise). Amplitude, frequency, and noise all moderated roughness. Observed interactions between parameters could reflect peripheral or attentional effects. Directional discrimination of graded frictional changes was well above chance, but did not indicate accessible and reliable differentiation that could readily be exploited in use contexts.

We present Tactile Echoes, a wearable system for augmenting tactile interactions with any object. This system senses vibrations in the fingertip that are produced by interactions of the finger with a touched object. It processes the vibration signals in real-time via a parametric signal network and returns them to the finger as "Tactile Echoes" of the touch interaction. Just as acoustic echoes continuously respond to sound, Tactile Echoes are continuously generated in response to the sensed tactile contacts. A short finger tap produces discrete Echoes, while a slide can yield continuous feedback. We also render the signals as sound, yielding multisensory feedback. Many different effects can be designed using ten signal processing parameters. Distinct effects may be assigned to different touched objects or surface regions by sensing the hand location in a mapped environment. We investigated how Tactile Echoes are perceived in a behavioral study using semantic differential scaling and multidimensional scaling methods. This yielded low-dimensional, semantically grounded representations of the perceptual similarities between different Echoes. This system holds promise for enabling evocative haptic effects during a wide range of free-hand tactile interactions.

The measurement of perceptual sensitivity can be used for the clinical diagnosis and assessment of skin conditions. However, conventional approaches to evaluating the direct relationship between perceptual sensitivity and the skin mechanical properties have limitations. This study proposed a new approach to achieving the simultaneous measurement of skin deformation and perceptual sensitivity. We introduced suction stimulation on the skin, which is commonly used for evaluating the skin mechanical properties. However, the standard suction stimuli cannot produce sufficient stimuli to be perceived. We solved this issue by applying oscillated suction pressure in the frequency of 10 Hz. We presented the device mechanism and control method of the pressure. As a pilot study, we investigated the relationship between the deformation of the forearm skin and perceptual sensitivity in thirteen participants. Experimental results suggested that the amount of skin displacement achieves better discrimination performance than the suction pressure levels.

Augmented and virtual reality are poised to deliver the next generation of computing interfaces. To fully immerse users, it will become increasingly important to couple visual information with tactile feedback for interactions with the virtual world. Small wearable devices which approximate or substitute for sensations in the hands offer an attractive path forward. In this work, we present Tasbi, a multisensory haptic wristband capable of delivering squeeze and vibrotactile feedback. The device features a novel mechanism for generating evenly distributed and purely normal squeeze forces around the wrist. Our approach ensures that Tasbi’s six radially spaced vibrotactors maintain position and exhibit consistent skin coupling. In addition to experimental device characterization, we present early explorations into Tasbi’s utility as a sensory substitution device for hand interactions, employing squeeze, vibration, and pseudo-haptic effects to render a highly believable virtual button.

Human perception of surface stickiness is closely related to intermittent slip dynamics, or stiction. In this work, we develop a method for real-time closed-loop rendering of surface stiction on an electroadhesive surface haptic display, and test it on a custom-built tribometer. We perform a psychophysical study to determine the effectiveness of a single, user-adjustable parameter on perceived surface stickiness, and elucidate what aspect of friction shapes the percept.

We have developed a large printable electrostatic tactile display based on electrostatic tactile and paper electronics technology. In this display, it is possible to impart tactile sensation to a specific part of a symbol alone by printing a color ink for that symbol on the electrode. The use of a paper medium makes the display easy to enlarge and develop at low cost and it can be rolled up, miniaturized and carried easily. We studied the possibility of uniform tactile presentation over a large area in this display, and the effect of the color ink layer on the perceived intensity. As a result, no large voltage drop due to enlargement of the display was observed. No difference in perceived intensity due to the amount of color ink used was found. The results thus confirmed that it is possible to print vivid graphics using large amounts of ink and that the proposed display can be used as a poster.
