Tactile perception of cognitive robots
Compared to other modalities like vision, tactile sensing has been so far neglected by robotic researchers. At the time of writing, tactile sensing devices that can just approach the performance of the human sense of touch seem out of reach. Despite this fact the use and exploitation of available …

Visuo-Tactile Perception for Dexterous Robotic Manipulation
In this thesis, we develop visuo-tactile perception to enable general and precise robotic manipulation. In particular, we want to study how to effectively process visual and tactile information to allow robots to expand their capabilities while remaining accurate and reliable. We begin our work by …

An extensible software library for developing tactile perception experiments
… researchers spend programming while developing tactile perception experiments. The system allows students to program in Matlab, a high-level, interpreted language, and captures functionality common to most experiments in an easily extensible library. To further aid the student, an experiment …

Tactile perception of spatially distributed vibratory stimuli on the fingerpad
Using a pin-array type tactile display as a stimulator of the finger pad, a psychophysical study was conducted on the vibrotactile perception. The passive touch with vibratory stimuli in the low frequency could be an alternative of the active touch for the presented stimuli: polygons, round shapes …

The Relationship of Tactile-Perception Ability to Intelligence and Reading Achievement in Younger Children
… of this study was to examine the relationship of tactile-perception ability to intelligence and reaching achievement in first and third grade children and to assess the usefulness of a tactile-perception measure to predict later reading achievement. Ninety-seven first graders and ninety third …

Incorporating High-Resolution Tactile Perception for Performative and Generalized Robotic Manipulation Through Compliance Estimation and Hardware Design
… teleoperated demonstrations. Humans rely on our tactile perception to perform contact-rich and dynamic manipulation tasks. By more seamlessly incorporating high-resolution tactile sensing and haptic feedback into teleoperation interfaces, we can work to create stronger demonstration data to …

Factors Influencing how Electrotactile Stimuli are Consciously Perceived
Tactile, or touch-related, perception is critical to successfully perform activities of daily living, such as holding a cup, hugging a loved one, or learning a new skill. However, approximately 30% of individuals in the United States experience tactile perceptual impairments, or …

Tactile tribology- investigation of tactile graphics and perception characterization using event-related potentials
<p>Tactile graphics are often used to present visual information to the blind and visually impaired (BVI). However, limitations in the skin’s perceptive resolution and inefficiencies in representing tactile information within a modest amount of page space pose challenges in representing scientific …

Design and control of an anthropomorphic robot finger with multi-point tactile sensation
… this research is to develop the prototype of a tactile sensing platform for anthropomorphic manipulation research. We investigate this problem through the fabrication and simple control of a planar 2-DOF robotic finger inspired by anatomic consistency, self-containment, and adaptability. The …

Dynamic Tactile Information is Sufficient for Precise Curvature Discrimination
<p>Our tactile perceptual experiences occur when we interact, actively and passively, with environmental objects and surfaces. Previous research has demonstrated that active manual exploration enhances the tactile perception of object shape. Nevertheless, the factors that contribute to this …

Tactile sensing of shape : biomechanics of contact investigated using imaging and modeling
… the biomechanics of skin as it pertains to human tactile sense. During touch, mechanoreceptors beneath the skin surface are mechanically loaded due to physical contact of the skin with an object and respond with a series of neural impulses. This neural population response is decoded by the central …

EBBINGHAUS ILLUSION IN TOUCH AS EVIDENCE FOR THE TWO STREAM PERCEPTION-ACTION HYPOTHESIS
… the existence of the Ebbinghaus illusion in the tactile modality. Participants underwent various tactile-tactile and tactile-visual conditions to actively explore Ebbinghaus illusion sets. Our results show that participants are more likely to be deceived when the illusory stimulus (the Ebbinghaus …

Validation and Comparison of Two Sensory Perceptual Examinations
… The comparison revealed that in the area of tactile perception and fingertip number writing perception, the discriminative validity of these tests was increased by procedural standardization. Conclusions. There are indications which suggest that procedural standardization could increase the …

Local Shape Estimation Using Mechanochromic Structurally-Colored Tactile Sensors
Tactile perception is increasingly used in robotics to augment the robot’s sense of its environment and the objects that it manipulates, particularly in cases where visual systems alone prove inadequate. Existing tactile sensors feel their surroundings by sensing many different types of tactile …

Reading Skins: A Braille Learning Facility in Old Town Alexandria
… it is readable. Our skin can gather data through tactile perception and read our spatial surroundings. Architecture is an expressive act and the only discipline that stimulates all of our senses. An architect designs spaces that foresee and celebrate the bodily interaction of the inhabitant. The …

Biomimetic Biomechanical Sensors for Intelligent Wearable Interfaces
… arterial pulses, respiratory rhythms, and tactile manipulation. Capturing these subtle signals with high fidelity can unlock transformative applications in silent communication, healthcare monitoring, and immersive human-machine interaction. However, current biomechanical sensors remain …

Deformable Object Manipulation with a Tactile Reactive Gripper
… To address these challenges, we propose a perception-driven framework that combines global visual understanding with local tactile feedback. Rather than modeling the full configuration of the object, we leverage local constraints, grounded in modular visual and tactile representations, to …

Tactility and modernity: the sense of touch in D. H. Lawrence, Alfred Stieglitz, Walter Benjamin, and Maurice Merleau-Ponty
… is to examine the unique importance of tactile perception in Western Modernism, focusing on three individuals and an artistic group, namely, D. H. Lawrence, Walter Benjamin, Maurice Merleau-Ponty, and an artistic circle centering around Alfred Stieglitz. In the tradition of Western …
