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 ...

Surface waves and spatial localization in vibrotactile displays [PDF]
2010 IEEE Haptics Symposium, 2010 The locus of vibrotactile stimulation is often used as an encoding cue in tactile displays developed for spatial orientation and navigation. However, the ability to localize the site of stimulation varies as a function of the number and configuration of the vibrating motors (tactors) in the display.

Crossmodal spatial location: initial experiments [PDF]
, 2006 This paper describes an alternative form of interaction for mobile devices using crossmodal output. The aim of our work is to investigate the equivalence of audio and tactile displays so that the same messages can be presented in one form or another ...

Evidence of Top-Down Sensory Prediction in Neonates Within 2 Days of Birth. [PDF]
Dev SciABSTRACT Recent studies have demonstrated top‐down modulation in perceptual cortices in infants as young as 6 months. However, it is unclear when and how this ability emerges given conflicting evidence available. This study investigates top‐down perceptual modulation by focusing on a neural signature referred to as top‐down sensory prediction, where ...

Independent component approach to the analysis of EEG and MEG recordings [PDF]
, 2000 Multichannel recordings of the electromagnetic fields emerging from neural currents in the brain generate large amounts of data. Suitable feature extraction methods are, therefore, useful to facilitate the representation and interpretation of the data ...

Multidimensional tactons for non-visual information presentation in mobile devices [PDF]
, 2006 Tactons are structured vibrotactile messages which can be used for non-visual information presentation when visual displays are limited, unavailable or inappropriate, such as in mobile phones and other mobile devices.

Relative vibrotactile spatial acuity of the torso [PDF]
, 2017 While tactile acuity for pressure has been extensively investigated, far less is known about acuity for vibrotactile stimulation. Vibrotactile acuity is important however, as such stimulation is used in many applications, including sensory substitution ...

Absolute localization of vibrotactile stimuli on the torso [PDF]
Perception & Psychophysics, 2008 Vibrotactile mobility systems present spatial information such as the direction of a waypoint through a localized vibration on the torso. Using these systems requires the ability to determine the absolute location of the stimulus. Because data are available only on the ability to determine the relative location of stimuli on the torso, we developed a ...

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.
