Evaluating the Optimum Distance between Voice Coil Actuators Using the Relative Point Localization Method on the Forearm

Actuators, 2022
While vibrotactile stimulation shows promise for sensory substitution devices, a crucial question concerns vibrotactile spatial resolution. We examined the optimum distance between three voice coil actuators (model: lofeltL5) on the forearm.

Electro-Haptic Stimulation: A New Approach for Improving Cochlear-Implant Listening

Frontiers in Neuroscience, 2021
Cochlear implants (CIs) have been remarkably successful at restoring speech perception for severely to profoundly deaf individuals. Despite their success, several limitations remain, particularly in CI users’ ability to understand speech in noisy ...

Generative Adversarial Networks for Localized Vibrotactile Feedback in Haptic Surfaces

2021 24th International Conference on Electrical Machines and Systems (ICEMS), 2021
Touch-screens are the most relevant interface in the context of human-computer interaction. Moreover, they are widely used as interaction means for digital musical instruments, where a complex action-perception loop is involved in the user experience. This is why reestablishing a rich vibrotactile feedback is of key importance for improving the quality

A Light-Driven Vibrotactile Actuator with a Polymer Bimorph Film for Localized Haptic Rendering

ACS Applied Materials & Interfaces, 2021
A vibrotactile actuator driven by light energy is developed to produce dynamic stimulations for haptic rendering on a thin-film structure. The actuator is constructed by adopting a thermal bimorph membrane structure of poly(3,4-ethylenedioxythiophene) doped with p-toluenesulfonate (PEDOT-Tos) coated onto a polyethylene terephthalate (PET) film.

Neurosensory sequelae assessed by thermal and vibrotactile perception thresholds after local cold injury [PDF]

International Journal of Circumpolar Health, 2014
Local freezing cold injuries are common in the north and sequelae to cold injury can persist many years. Quantitative sensory testing (QST) can be used to assess neurosensory symptoms but has previously not been used on cold injury patients.To evaluate neurosensory sequelae after local freezing cold injury by thermal and vibrotactile perception ...

Localization of Vibrotactile Stimuli on the Face

CoRR
The face remains relatively unexplored as a target region for haptic feedback, despite providing a considerable surface area consisting of highly sensitive skin. There are promising applications for facial haptic feedback, especially in cases of severe upper limb loss or spinal cord injury, where the face is typically less impacted than other body ...
