Sound-to-Touch Sensory Substitution and Beyond
… affordable, non-surgical, and works in adults. "Sensory substitution"--the concept that information can be effectively mapped from one sense to another--has the potential to overcome all of these issues: it is non-invasive (and therefore inexpensive and less regulated) and leverages a developed …

Vibrotactile sensory substitution for post-stroke rehabilitation
… and loss of sensation in one side of their body. Sensory feedback in the hand is used to assess if the individual is using appropriate grip force to hold and use objects; lack of sensory feedback can lead to dropped or damaged objects, and possible hand injury. Existing force biofeedback devices …

Sensory substitution for force feedback in space teleoperation
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 1992.

THE NECK AS A POTENTIAL SITE FOR VESTIBULAR TACTILE SENSORY SUBSTITUTION
… could be used a site for vestibular-to-tactile sensory substitution, two experiments were performed to take an in-depth look of the tactile sensitivity of the neck and how it responds to vibrotactile stimuli. Experiment 1 explored how participants respond to a vibrotactile neck device, the …

Digital Synesthesia : using mobile technology and sensory substitution to interact with our world
… perception of information that is outside of our sensory spectrum. Modern technology already offers the ability to detect this information, but what has not been achieved is a way for our brains and body to incorporate this new information as a part of our sensory tool-belt. Then we can truly …

FingerEye: An Electrotactile-mechanism Enabled Adaptive Sensory-substitution Aid for the Blind and Visually Impaired
The objective of this research is to investigate, design and validate a wearable electro-Braille device and associated fingertip skin stimulation mechanisms for the blind or visually impaired (BVI). The final goal is to develop a novel electrotactile-based Braille (E-Braille) technology that helps …

Development of a low-cost high-impact resistant compliant myoelectric prosthetic hand
… failure due to accidental impact and lack of sensory feedback are one of the main reasons why people with upper-limb amputations abandon commercially-available prosthetic hands. To address this problem, this thesis presents the design and evaluation of a compliant four-bar linkage mechanism …

Champagne for the Blind : Paul Bach-y-Rita, neuroscience's forgotten genius
… theory of neuroplasticity. He is the father of sensory substitution, a field which explores how one sensory modality can be transferred to another. This work culminated in the invention of the Brainport, a device that transmits information through electrodes on the tongue. Bach-y- Rita's …

Perception of patterned vibratory stimulation: An evaluation of the tactile vision substitution system
<p>Sensory substitution--The replacing of an impaired sensory channel by a properly functioning one--is possibly best manifested today in attempts to provide visual aids for the blind. The tactile vision substitution system (T.V.S.S.) is an example of one such visual aid. The system presents …

Perturbation-based detection and prosthetic correction of vestibulopathic gait
… the use of a novel wearable vibrotactile sensory substitution device for enhanced postural and locomotor stability. The balance prosthesis is composed of an inertial motion-sensing system mounted on the lower back, a vibrotactile display worn around the torso, and a computer controller.

Performance and Usability of Force Feedback and Auditory Substitutions in a Virtual Environment Manipulation Task
… understanding of whether or not haptics or sound substitutions improved manipulation performance or usability in VE applications. Twenty-four volunteers (12 males and 12 females) participated in a 2 (haptics) x 2 (sound) x 2 (gender) mixed factorial experiment in which they completed a VE …

Perceptual and comparative analyses of a passive, linear, multiple degree-of-freedom skin stretch device for proprioceptive substitution
This thesis presents a passive linear skin stretch device and shows that this device can provide multiple degree-of-freedom proprioceptive information about a myoelectric prosthetic hand during grasping. The device consists of three plastic contact pads that are adhered to the skin on the glabrous …

MusiKeys: Exploring Auditory-Physical Feedback Replacement for Mid-Air Text-Entry
Extended reality (XR) technology is positioned to become more ubiquitous in life and the workplace in the coming decades, but the problem of how to best perform precision text-entry in XR remains unsolved. Physical QWERTY keyboards are the current standard for these kind of tasks, but if they are …

Increasing Functional Task Performance in Adults with Low Vision
… adults with low vision utilizing tactile vision substitution systems, specifically tongue display units (TDUs). TDUs are a novel assistive device that functions to provide artificial vision to those with low vision. TDUs pixelate images captured on a camera the person wears and the images are …

Mechanisms for enabling closed-loop upper limb sensorimotor prosthetic control
… are limited in their ability to provide sensory feedback to a user. The lack of sensory feedback forces prosthesis users to rely on visual feedback alone in manipulating objects, and often leads to abandonment of the prosthesis in favor of the user's unimpaired arm. Consequently, there is …

Affordances In The Design Of Virtual Environments
… realized in the natural world and how lack of sensory stimuli may lead to realization failures in virtual environments. Implications of the model were empirically investigated by examining three affordances: passability, catchability, and flyability. The experimental design involved four …
