Development of thermal displays for haptic interfaces
This thesis studied the effect of different stimulus parameters on the thermal response of the skin. A set of thermal patterns, known as thermal icons, was presented to participants using a thermal display mounted on the hand. The thermal responses of the skin were studied to understand which …

Development and evaluation of a thermal model for haptic interfaces
The thermal interaction between the skin and an object is influenced by the thermal properties and initial temperatures of the skin and object, and by the contact force and surface roughness of the contact surfaces. This thermal interaction is modeled in this research which characterizes the …

Non-visual Access to the World Wide Web: Investigations of Design Guidelines and Haptic Interfaces.
… of Web content was investigated using a haptic device. The perception of virtual textures and objects by blind and sighted people via this device was examined. It was found that the virtual textures were perceived differently to the real textures examined in the literature, and that the …

Sensory Encounters in the Age of Computation
… in multimodal media. From the history of haptic interfaces to the data practices of social media communities across the US and China, this thesis uses historical and ethnographic methods to understand how users of quantitative information encode norms about gender, ability, and race in …

Virtual reality simulation modeling for tele-surgery and tele-haptic class of applications
The incorporation of Haptic interfaces in Collaborative Virtual Environments (CVE) suffers from setbacks due to an inherent technical problem that occurs when the users are geographically distributed. The main causes of such discrepancies are network delay, a lack of view of individual …

Digital Control Techniques for High Fidelity Haptic Simulation Systems
Haptic simulation systems allow human users to kinesthetically interact with virtual environment models through a robotic mechanism known as a haptic interface. The sampled-data nature of haptic interfaces limits the range of virtual environment dynamics that can be stably rendered in a haptic …

Controle inteligente de vibrações utilizando amortecedor magneto reológico
… biomechanics area with intelligent protheses and haptic interfaces wich simulate the tactile sensing. MR dampers feature several desirable features such as high power controllability, low power consumption, stability, wide operational temperature range, fast response time and compact size. …

Affective social quest (ASQ) : teaching emotion recognition with interactive media & wireless expressive toys
… that a system that manipulated movies and haptic interfaces was feasible and second, such a system could augment and potentially automate some of the human-intensive, repetitive aspects of existing behavioral therapy techniques. All six children responded to and attended to the system, with …

Adaptive Communication Interfaces for Human-Robot Collaboration
… can use a collection of auditory, visual, or haptic interfaces to convey information to human collaborators. The way these interfaces select signals typically depends on the task that the human is trying to complete: for instance, a haptic wristband may vibrate when the human is moving quickly …

Communication-Driven Robot Learning for Human-Robot Collaboration
… learning approach, we integrate a wrapped haptic display that explicitly communicates representations from the robot's learned behavior to the user. We show that our framework helps the human teacher improve different aspects of the robot's learning during kinesthetic teaching. We then …

Role of torque in haptic perception of virtual objects
… to determine the role of torque feedback in haptic perception of object location within virtual environments. The experimental setup consisted of two Phantom haptic interfaces connected by a common stylus and a raybased rendering technique for modeling the interactions between the …

Navigating the Unseen: A Haptic Glove for Peripersonal Navigation in Low-Visibility Scenarios
… goals centered on developing and evaluating a haptic glove that delivers vibrotactile feedback to support peripersonal navigation in low-visibility scenarios. Study 1 examines how tactor placement, hand motion, and temporal patterns influence vibrotactile perception. Twenty-two right-handed …

Design of programmable matter
… tools, rapid prototyping, and sculpture-based haptic interfaces. Programmable matter would be composed of millimeter-scale autonomous microsystem particles, without internal moving parts, bound by electromagnetic forces or an adhesive binder. Particles can dissipate 10 mW heat, and store 6 J …

Does Virtual Haptic Dissection Improve Student Learning? : A Multi-Year Comparative Study
… the cutting through anatomical layers with a haptic (tactile) interface. This study investigated the haptic ‘dissection’ of a three dimensional digital model of the hand and wrist in anatomy education at both undergraduate (UG) and postgraduate (PG) levels. The model was used as a teaching and …

Haptic Interface for Non-Visual Steering
… significant cause of traffic accidents. Existing haptic automotive interfaces typically indicate when and in which direction to steer, but they don't convey how much to steer, as a driver typically determines this using visual feedback. We present a novel haptic interface that relies on an …

Fully Aerosol-Jet Printed Trilayer Electrochemical Actuator
… robots for environmental monitoring, and haptic interfaces. Electrochemical actuators (ECAs) are a promising candidate for these applications due to their capability for large deformations at low actuation voltages (<1 V) and their potential to be scaled down to very small sizes (~μm or …
