What was done

This narrative review synthesizes academic and industry literature on non-invasive haptic devices that transmit information to the nervous system via vibration patterns on the skin. The authors categorize and describe applications across sensory substitution (e.g., sound-to-touch for hearing loss), sensory expansion (e.g., detecting electromagnetic radiation outside visible light), and sensory addition (e.g., magnetoreception).

What was found

The abstract reports no numerical findings, quantitative metrics, or statistical outcomes; it provides a conceptual summary and descriptive classification of sensory manipulation using haptic interfaces.

Why it matters

The review outlines how non-invasive haptic interfaces can serve not only as assistive technologies for sensory loss but also as tools for augmenting human perception with novel sensory modalities.

Limits

This is a narrative review that presents no new empirical data, quantitative comparisons, or systematic review methodology, and the abstract does not assess device efficacy, usability, or neuroplastic adaptation limits.
