Is a tactile vision substitution device for reading?
One form of noninvasive tactile vision substitution is a tongue display unit (TDU), which is a form of portable sensory substitution that uses tactile sensation to substitute for the absence visual sensation.
What is a sensory substitution device?
Sensory substitution (SS) devices (e.g., vOICe) can assist the blind by encoding a video stream into a sound pattern, recruiting visual brain areas for auditory analysis via crossmodal interactions and plasticity. SS devices often require extensive training to attain limited functionality.
Which of the following is example of sensory substitute device?
The first sensory substitution device was the white cane which is still widely used by the blind community. Braille is another example of tactile sensory substitution, and software programs such as JAWS substitute are auditory based.
Can tactile senses be influenced by vision?
In sum, the results of these studies indicate that vision generally enhances the speed of tactile target detection and tactile resolution at the visually attended location on the body surface.
What is sensory augmentation?
Sensory augmentation: integration of an auditory compass signal into human perception of space.
What is sensory addition?
This process is called sensory addition. In Eagleman’s project, it involves sending real-time data from the internet into the brain via the VEST device. His team is already training individuals to make informed decisions on the buying and selling of stocks by feeding stock market data into the VEST.
What are the tactile senses?
Tactile (touch) Tactile receptors identify the sensation of touch and are all over our bodies in our skin. Some areas of our skin have more tactile receptors than other areas e.g. mouth and hands. The tactile senses are important for identifying touch, pressure, pain, temperature and texture.
What are the sensory devices?
6 Different Types of Sensory Imagery
- Visual imagery engages the sense of sight.
- Gustatory imagery engages the sense of taste.
- Tactile imagery engages the sense of touch.
- Auditory imagery engages the sense of hearing.
- Olfactory imagery engages the sense of smell.
What is sense substitution?
the perception of a stimulus normally analyzed by one sense through the activity of another sense. Tactile sensations can substitute for visual input, for example, when the visual world is transcribed into tactile sensations for an individual who is blind.
How are vision and touch related?
In both vision and touch, the brain perceives objects in motion as they move across a sheet of sensor receptors. For touch, this is the set of receptors laid out in a grid across the skin; in vision, these receptors are in the retina. As we run our fingertip across a surface, nearby receptors are excited sequentially.
What is cross modality?
Cross-modal matching refers to the ability to recognize objects presented in two different sensory modalities. For example, an object presented visually could be discriminated using touch, or a photograph of a familiar person could be identified from a recording of their voice.
Are there any sensory substitution devices for blindness?
There are two major classes of sensory substitution devices for blindness, based upon either tactile or auditory input. These are referred to as respectively tactile-to-vision sensory substitution (TVSS) and auditory-to-vision sensory substitution (AVSS) devices.
How is sensory substitution used in sensory substitution systems?
Auditory sensory substitution systems like the tactile sensory substitution systems aim to use one sensory modality to compensate for the lack of another in order to gain a perception of one that is lacking.
How are visual prostheses different from sensory substitution systems?
In contrast to sensory substitution systems, the visual prostheses do not take advantage of the natural reorganization of the cortex of the blind since such invasive approaches attempt to stimulate the deficient sensory system directly.
How is sensory data transformed into tactile stimuli?
The visual or auditory data collected from the sensors is transformed into tactile stimuli that are then relayed to the brain for visual and auditory perception. Crucially, this transformation sustains the sensorimotor contingency inherent to the respective sensory modality.
