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.

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.

We present HaptiGlow, a technique that combines ultrasound haptics with peripheral visual feedback to help users find where to place their hand for improved mid-air interaction. Hand position is important. If a user’s hand is poorly placed, input sensors may have difficulty recognising their gestures. Mid-air haptic feedback is also hard to perceive when the hand is in a poor position. Our novel feedback addresses this important usability problem. Our results show the combination of ultrasound haptics and peripheral visuals is effective, with the strengths of each leading to accurate (23mm) and fast (4.6s) guidance in a 3D targeting task. Our technique improves midair interaction by easily helping users find a good hand position.

Tactile stimulation of the skin excites cutaneous waves that travel tens of centimeters, but the implications for haptic engineering and perception are not well understood. We present evidence from optical vibrometry that tactile motion cues delivered via air-coupled ultrasound excite complex spatiotemporal wave fields in the hand. We distinguished two physical regimes based on the ratio of the motion speed to the cutaneous wave speed. At low speeds (1-4 m/s), waves generated by a moving stimulus propagated to similar distances in all directions. At high speeds (4-15 m/s), waves in the direction of motion were compressed. We also studied tactile motion perception at these speeds, which were faster than those used in prior studies. Motion sensitivity was impaired when waves were inhibited in front of the moving stimulus. This occurred for motion at high speeds and across disconnected skin areas. Together, our findings suggest that tactile motion perception is aided by waves propagating in the skin. This paper presents the first time-resolved observations of cutaneous responses to focused ultrasound, and contributes practical knowledge for the use of tactile motion and mid-air haptic feedback.

The deployment of visual spatial attention can be significantly influenced in an exogenous, presumably bottom-up manner. Traditionally, spatial cueing paradigms have been utilized to come to such conclusions. Although these paradigms have primarily made use of visual cues, spatially correspondent tactile cues have also been successfully employed. However, one property of tactile cues not thoroughly explored in this context is the influence of their specific directionality on the subsequent deployment of visual attention. Thus, the current study sought to evaluate the potential utility of small, directional tactile cues as a means to exogenously direct visual spatial attention. Tactile cues were employed by a small shearing of the fingertip’s skin in either the leftward of rightward direction. A modified spatial cueing paradigm was used to compare reaction time performance across both traditional-visual and directionaltactile cues at cue-target onset asynchronies of 100, 200, 400 and 800 ms. The results indicated that both visual and tactile cues mediated the deployment of exogenous visual spatial attention. However, differences between the two modalities were observed in terms of both the magnitude and the pattern of the associated cueing effects. Further, there appeared to be a general rightward bias in performance irrespective of cue modality. Overall, the current work offers preliminary evidence that small, directional tactile stimulation may influence the allocation of attention across space in a manner at least partially distinct to traditional visual cueing tasks. Yet, further research will be required to explicitly determine the underlying mechanisms.

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.
