Cross-modal (Cross-modal Correspondence, Cross-modal Perception)
The phenomenon whereby information or stimulation in one sensory modality (such as vision) systematically influences or corresponds with perception in another modality (such as hearing or touch). In a…
Electrotactile (Electrotactile Stimulation, Electrical Tactile Stimulation)
A form of tactile feedback that applies controlled electrical current to stimulate touch nerve endings in the skin, creating sensations of pressure, tingling, or texture. Electrotactile displays can a…
Electrotactile Feedback (Electrotactile, Electrical Tactile Stimulation)
A form of haptic feedback that uses controlled electrical current applied directly to the skin or through a thin insulating layer to generate tactile sensations. Unlike vibrotactile feedback (which us…
Parallax (Visual Parallax, Binocular Parallax)
Parallax is the apparent displacement or difference in position of an object when viewed from two different vantage points. In human vision, binocular parallax — the slight difference between the imag…
