Journal ArticleDOI
Somatotopical feedback versus non-somatotopical feedback for phantom digit sensation on amputees using electrotactile stimulation
TL;DR: SF was better than NF in general, but the practical issues such as the limited area of stumps could constrain the use of SF, and thus the 3C/SF modality was a good compromise.
Journal ArticleDOI
Effects of Different Tactile Feedback on Myoelectric Closed-Loop Control for Grasping Based on Electrotactile Stimulation
TL;DR: Results indicate that slip feedback is better than pressure feedback; pressure + slip feedback can improve grasping rapidity; slip feedback significantly contributes to grasping economy and stability; and pressure + Slip feedback can perform as well as vision feedback.
Journal ArticleDOI
Quantifying Different Tactile Sensations Evoked by Cutaneous Electrical Stimulation Using Electroencephalography Features.
TL;DR: The work suggests that ERP- and ERS/ERD-based EEG features may have potential to quantify tactile sensations for medical diagnosis or engineering applications.
Proceedings ArticleDOI
UltraShiver: Lateral force feedback on a bare fingertip via ultrasonic oscillation and electroadhesion
TL;DR: A new lateral force feedback device is proposed, the UltraShiver, which employs a combination of in-plane ultrasonic oscillation and out-of-plane electroadhesion and can achieve a strong active lateral force on the bare fingertip while operating silently.
Journal ArticleDOI
UltraShiver: Lateral Force Feedback on a Bare Fingertip via Ultrasonic Oscillation and Electroadhesion
TL;DR: A lumped-parameter model is developed to understand the physical underpinnings of the UltraShiver and their influence on lateral force, and the model with frequency-weighted electroadhesion forces shows good agreement with experimental results.
