“…To date, designs selected for MDS analysis generally consist of a modest repertoire of features, such as only a few force values or frequency components. For example, one study working with an electroadhesive screen generated a coarse texture set consisting of only two friction levels [18]. The authors varied the overall friction difference, as well as the line width and spacing for different tessellated patterns, and found that parameters related to intensity, such as line thickness and friction levels, dominated perception.…”

Friction modulation technology enables the creation of textural effects on flat haptic displays. However, an intuitive and manageably small design space for construction of such haptic textures remains an unfulfilled goal for user interface designers. In this paper, we explore perceptually relevant features of fine texture for use in texture construction and modification. Beginning with simple sinusoidal patterns of friction force that vary in frequency and amplitude, we define irregularity as a third building block of a texture pattern and show it to be a scalable feature distinct from the others using multidimensional scaling. Additionally, subjects' verbal descriptions of this 3-dimensional design space provide insight into their intuitive interpretation of the physical parameter changes.

“…Therefore, further investigation is usually conducted by analyzing additional ratings using subjective measures [39]. The most common approach is discovering semantic information related to perception by using adjectives as descriptors [40], [41]. In contrast, some studies have applied physical properties directly as descriptors to find systematic relationships between physical and perceptual properties because the responses to construct perceptual spaces are based on the apparent physical properties in tactile stimuli [36], [42].…”

Haptics researchers often endeavor to deliver realistic vibrotactile feedback through broad-bandwidth actuators; however, these actuators typically generate only single-axis vibrations, not 3D vibrations like those that occur in natural tool-mediated interactions. Several three-to-one (321) dimensional reduction algorithms have thus been developed to combine 3D vibrations into 1D vibrations. Surprisingly, the perceptual quality of 321-converted vibrations has never been comprehensively compared to rendering of the original 3D signals. In this study, we develop a multi-dimensional vibration rendering system using a magnetic levitation haptic interface. We verify the system's ability to generate realistic 3D vibrations recorded in both tapping and dragging interactions with four surfaces. We then conduct a study with 15 participants to measure the perceived dissimilarities between five 321 algorithms (SAZ, SUM, VM, DFT, PCA) and the original recordings. The resulting perceptual space is investigated with multiple regression and Procrustes analysis to unveil the relationship between the physical and perceptual properties of 321-converted vibrations. Surprisingly, we found that participants perceptually discriminated the original 3D vibrations from all tested 1D versions. Overall, our results indicate that spectral, temporal, and directional attributes may all contribute to the perceived similarities of vibration signals.

“…For each adjective pair/semantic word, we applied multiple linear regression with the button coordinates recovered from the perceptual space as independent variables and the subjective score as a dependent variable. Then we projected each adjective pair/semantic word to a line in the perceptual space, which passes the origin and has a direction proportional to the standardized regression coeffcients [16,38]. Each projected line represents a perceptual axis along which the feeling represented by the adjective pair/semantic word varies.…”

“…The task was an adjective rating using seven bipolar adjectives with opposing meanings and three semantic words, as listed in Table 2. The adjectives were chosen from the literature on haptic texture perception and articles about switches and buttons [17,25,36,38]. In each trial, participants perceived the stimulus by pressing the designated button on a GUI as many times as they wanted.…”

“…Results are mapped into the perceptual space to obtain extrinsic geometric interpretations of the stimuli, namely, perceptual dimensions. This approach has been an exceedingly effective tool in comprehending the perceptual structure of many types of haptic stimulus, e.g., texture [16,38,40], vibration [17,18,25,44,47,57], and material [58]. In particular, the sensations of button press were analyzed using perceptual spaces for 10 real and 14 force-feedback buttons [32], 23 physical buttons [36], and 18 touchscreen virtual buttons [10].…”

Physical buttons provide clear haptic feedback when pressed and released, but their responses are unvarying. Physical buttons can be powered by force actuators to produce unlimited click sensations, but the cost is substantial. An alternative can be augmenting physical buttons with simple and inexpensive vibration actuators. When pushed, an augmented button generates a vibration overlayed on the button's original kinesthetic response, under the general framework of haptic augmented reality. We explore the design space of augmented buttons while changing vibration frequency, amplitude, duration, and envelope. We then visualize the perceptual structure of augmented buttons by estimating a perceptual space for 7 physical buttons and 40 augmented buttons. Their sensations are also assessed against adjectives, and results are mapped into the perceptual space to identify meaningful perceptual dimensions. Our results contribute to understanding the benefts and limitations of programmable vibration-augmented physical buttons with emphasis on their feels.
