Effect of Tactile Feedback on Performance
… environmental interaction 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 …

Stable and Semantic Robotic Grasping Using Tactile Feedback
… estimates the stability of a grasp based on tactile feedback and hand kinematic data. We then show our hand adjustment algorithm which works with the grasp stability estimator and synthesizes hand adjustments to optimize a grasp towards a stable one. With these two methods, we obtain a …

Effect of Tactile Feedback on Reducing Body Sway in Elderly
… to examine the effect of 6 minutes training of tactile feedback (novel intervention) compared to visual feedback on body sway in the elderly with or without diabetes to develop a new technique for balance training. Design: A single blinded randomized controlled trial. Setting: Loma Linda …

Creating tactile feedback with intelligent electrical stimulation to compensate for sensory impairment.
… to an increased risk of falls and injuries. Biofeedback, in the form of electrocutaneous stimulation, can be used as a means to transmit information about the force and pressure applied to the feet, and this can help people determine their body position in relation to the ground and the amount …

The Effects of a Remote Control Tactile Feedback System on Conversation Skills in Children with Autism.
… have examined the effects of a remote control tactile device (RCT) as an unobtrusive prompting method used to promote skills such as verbal initiations and play behaviors in children with autism. To date, however, no published studies have investigated the effects of the RCT as a consequence to …

Second Skin : motion capture with actuated feedback for motor learning
… three-dimensional (3D) motion tracking with tactile feedback for the purpose of improving users' motor-learning ability. Such a system would track a user's body and limb movements as he or she performs an action, and then give the user automatic, real-time tactile feedback to aid in the …

Delivering Expressive And Personalized Fingertip Tactile Cues
… in recent years, but providing realistic tactile feedback is not a challenge that is soon to be solved. Daily interactions with physical objects elicit complex sensations at the fingertips. Furthermore, human fingertips exhibit a broad range of physical dimensions and perceptive abilities, …

Design of a pressure sensing laparoscopic grasper
… Current devices provide surgeons with limited tactile feedback, and the current alligator-style jaws create pinch points that can lead to torn or damaged tissue. Additionally, the angled jaws can result in excessive grasping forces, due to the uneven pressure distribution along the jaws, or …

Interactive Touch for Manipulation
… several hardware platforms equipped with tactile sensing and integrated perception and control frameworks to apply interactive touch to real-world manipulation tasks. (1) We use touch for manipulating deformable objects like cables, using real-time tactile feedback during sliding. The …

Barometer-Based Tactile Sensing: Characterization, Processing, and Applications for Dynamic Manipulation
Reliable tactile feedback is essential for robotic systems to interact effectively with their environments, especially in dynamic manipulation tasks where detecting contact onset, direction, and force is critical for control and planning. This thesis advances the development of barometer-based …

Deformable Object Manipulation with a Tactile Reactive Gripper
… 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 enable robust, reactive, and generalizable manipulation. The primary contributions …

Simulation-Based Design Strategies for Component Optimization in Steer-by-Wire Applications.
… model. This model is used to investigate the tactile feedback performance of various SBW configurations at specific driving conditions. Although peak performance is obtained with fully active components (direct-drive electric motors), comparable performance can be obtained using a combination …

Safe Object Manipulation Strategies Using Tactile Sensors
Tactile feedback is essential for object manipulation tasks for humans and robots, facilitating reactive control even without vision. This dissertation introduces several tactile-based methodologies to enhance the manipulation performance and safety of robotic systems. Before presenting these …

Development of an augmented haptic control for in-vehicle law enforcement applications
… using an Immersion rotary haptic knob and a tactile feedback indicator. The parameters of this interaction design were explored through experimentation with a group of subjects using a testing procedure. From this information a prototype controller was developed and optimized to provide …

Mechanical constraints as common ground between people and computers
… mechanical constraints that combines some of the tactile feedback and affordances of mechanical systems with the abstract computational power of modern computers. The interface is based on a tabletop interaction surface that can sense and move small objects on top of it. Computation is merged with …

Vision-based proprioception and tactile sensing for soft robots
… deployment demands accurate proprioception and tactile feedback. This thesis introduces a compact, vision-based sensing framework that delivers both modalities from a single internal camera. We instantiate the approach on PneuGelSight, a pneumatically actuated finger that uses color-coded …
