Sensingthrough

Sensingthrough is a term used in human-computer interaction and neuroengineering to describe perceiving environmental information through non-traditional sensory channels. It encompasses techniques that translate data into perceptual cues that a user can interpret, thereby extending or substituting natural senses. The concept includes sensory substitution, sensory augmentation, and multisensory integration.

Common approaches include vibrotactile arrays mapping visual data to skin sensations, electrotactile or tongue stimulation, and auditory sonification. Some research explores direct neural interfaces. Key design considerations include latency, learning curves, perceptual interpretation, and safety.

Applications span assistive technology for visual impairment and navigation, as well as virtual and augmented reality training and undersea or hazardous-environment exploration. Sensingthrough remains primarily experimental and research-oriented, with prototypes and early deployments rather than widespread products. It functions as an umbrella for efforts to expand perception through technology rather than a single device.

Related concepts overlap with sensory substitution, sensory augmentation, and brain-computer interface research. Notable historical examples include devices such as the vOICe and BrainPort, which illustrate how environmental information can be conveyed through alternative channels. Ongoing work continues to address perceptual plasticity, user training, and practical deployment considerations.
