Vibrotactile adaptation fails to enhance spatial localization in adults with autism [PDF]
Brain Research, 2007 A recent study (Tannan et al., 2006) showed that pre-exposure of a skin region to a 5 sec 25 Hz flutter stimulus (“adaptation”) results in an approximately 2-fold improvement in the ability of neurologically healthy human adults to localize mechanical stimulation delivered to the same skin region that received the adapting stimulation.

Object Localization Assistive System Based on CV and Vibrotactile Encoding
CoRR, 2022 Intelligent assistive systems can navigate blind people, but most of them could only give non-intuitive cues or inefficient guidance. Based on computer vision and vibrotactile encoding, this paper presents an interactive system that provides blind people with intuitive spatial cognition.

A Large-Area Broadband Multimodal Dual-Resonant Haptic Device for Bidirectional Telerobotic and Augmented Interactions. [PDF]
Adv Sci (Weinh)We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned

Vibrotactile localization on the arm: Effects of place, space, and age [PDF]
Perception & Psychophysics, 2003 Although tactile acuity has been explored for touch stimuli, vibrotactile resolution on the skin has not. In the present experiments, we explored the ability to localize vibrotactile stimuli on a linear array of tactors on the forearm. We examined the influence of a number of stimulus parameters, including the frequency of the vibratory stimulus, the ...

Somatosensory cross-modal activation and changes in cortical somatosensory evoked potential responses in single-sided deafness: an EEG study [PDF]
Frontiers in NeuroscienceBackgroundThe neural mechanisms underlying somatosensory processing in individuals with acquired single-sided deafness (SSD) and potential central neuronal cross-modal reorganization remain largely unexplored. This study investigates the impact of SSD on

Effects of Using Vibrotactile Feedback on Sound Localization by Deaf and Hard-of-Hearing People in Virtual Environments [PDF]
Electronics (Switzerland), 2021 Sound source localization is important for spatial awareness and immersive Virtual Reality (VR) experiences. Deaf and Hard-of-Hearing (DHH) persons have limitations in completing sound-related VR tasks efficiently because they perceive audio information differently.

The intensity order illusion: temporal order of different vibrotactile intensity causes systematic localization errors [PDF]
Journal of Neurophysiology, 2019 Haptic illusions serve as important tools for studying neurocognitive processing of touch and can be utilized in practical contexts. We report a new spatiotemporal haptic illusion that involves mislocalization when the order of vibrotactile intensity is manipulated.

Humans Use a Temporally Local Code for Vibrotactile Perception [PDF]
eneuro, 2021 AbstractSensory environments are commonly characterized by specific physical features, which sensory systems might exploit using dedicated processing mechanisms. In the tactile sense, one such characteristic feature is frictional movement, which gives rise to short-lasting (<10 ms), information-carrying integument vibrations.

Modeling and Experimental Evaluation of Haptic Localization Using Electrostatic Vibration Actuators
IEEE Access, 2023 Touch screen devices have become ubiquitous in modern day-to-day lives. While smaller touchscreen devices provide enough user engagement with meaningful haptic feedback, large touch devices still lack meaningful haptic stimulation.
