Tactile Textile
The study is focused on the roles and principles of textiles, textile manipulation and its potential relationship with landscape architecture. Tactility bonds the two worlds of fashion and landscape together. It changes in scale, intimacy and movement. The study explores how textiles perform in …

TEXterity: Tactile Extrinsic deXterity
This thesis introduces the concept of TEXterity (Tactile Extrinsic deXterity) to address challenges in robotic manipulation. Focusing on tactile sensing, TEXterity aims to enhance dexterity by enabling robots to perceive and act upon extrinsic contact between the grasped object and the environment. …

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 …

Visual-tactile stop signal inhibition
… upon infrequent presentation of visual or tactile stop signals. Participants were to perform fast saccadic or manual responses to a visual or tactile target, but to cancel the response on the 25% of trials in which a stop signal of the other sensory modality was additionally presented. …

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 …

Soft, Compliant Tactile Robotic Manipulators
… we also want to incorporate high-resolution tactile sensors, which will allow soft robots to perform more tasks. One such system is the GelSight sensor, which is low-cost, effective, and high-resolution. However, the integration of these camera-based sensors into compliant manipulators is …

Tactile sensing using elastomeric sensors
GelSight, namely, elastomeric sensor, is a novel tactile sensor to get the 3D information of contacting surfaces. Using GelSight, some tactile properties, such as softness and roughness, could be gained through image processing techniques. In this thesis, I implemented GelSight principle to …

Effect of Tactile Feedback on Performance
… with the absence of feedback from the tactile channel. The majority of computer operation is completed visually because currently, the primary feedback humans receive from computers is through the eyes. This strong dependence on the visual modality can cause visual fatigue and fixation …

A tactile communication system for navigation
A vibrotactile display for use in navigation has been designed and evaluated. The arm and the torso, which offer relatively large and flat surface areas, were chosen as locations for the displays. The ability of subjects to identify patterns of vibrotactile stimulation on the arm and torso was …

Tactile measurement with a GelSight sensor
… with GelSight. GelSight is an optical-based tactile sensor that uses a piece of coated elastomer as the contact medium. A camera records the distortion of the elastomer during contact. This sensor can obtain a high-resolution view of the contact surface geometry, which is a breakthrough for …

Tactile sensors based on soft polymers
Piezoresistive carbon black/polydimethysiloxane (CB/PDMS) is a widely used material in the field of artificial skin development because of its high gauge factor to all forms of stress, including tension, compression and shear. While its durability, inexpensive-ness and customizability make CB/PDMS …

Tactile Vision: The Work of Giuseppe Penone
<p>This dissertation considers the early works of the Italian artist Giuseppe Penone. I argue that his works from the 1960s and 1970s are especially distinct from everything else he has made in the years since. The following chapters will show how descriptions and interpretations of Penone's art …
