Vibrotactile localization on the abdomen: Effects of place and space [PDF]
Perception & Psychophysics, 2004 In this study, we explore the conditions for accurate localization of vibrotactile stimuli presented to the abdomen. Tactile orientation systems intended to provide mobility information for people who are blind depend on accurate identification of location of stimuli on the skin, as do systems designed to indicate target positions in space or the ...

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.

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 ...

Effects of Using Vibrotactile Feedback on Sound Localization by Deaf and Hard-of-Hearing People in Virtual Environments [PDF]
Electronics, 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.

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.

Nonlinear Asymmetric Blood Oxygenation Level Dependent Responses in Somatosensory Cortex [PDF]
Hum Brain MappBOLD responses to increments and decrements in intensity of vibrotactile stimulation were asymmetric. Negative BOLD effects (decrements in signal) were smaller in amplitude and slower to peak compared with positive BOLD responses to increases of intensity. BOLD responses were nonlinear for changes in stimulus duration and intensity.

Object Localization Assistive System Based on CV and Vibrotactile Encoding
2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 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.

Sinusoidal Vibration Source Localization in Two-Dimensional Space Around the Hand
Frontiers in Psychology, 2022 There are use cases where presenting spatial information via the tactile sense is useful (e.g., situations where visual and audio senses are not available).
