Paresens

Paresens is a fictional concept frequently appearing in science fiction and worldbuilding. It denotes a distributed sensory augmentation system that links two or more participants, allowing them to share perceptual data in real time or to experience another person's sensory world. Although not present in current science, the term is used in speculative contexts to discuss interoperability, ethics, and identity in future technologies.

The name Paresens derives from the Latin roots par- meaning equal or paired, and sens- from sensus sense.

Typically, Paresens is depicted with wearable or implantable hardware: neural interfaces, sensor arrays, and a synchronization hub. Data streams—visual, auditory, tactile, and proprioceptive cues—are mapped into a common perceptual space so that each participant experiences a merged or alternate sensory field. The system includes consent controls, privacy safeguards, and a fallback mode to prevent overloading users.

Variants in fiction include asymmetric Paresens that allow one operator to influence the shared field, and retrospective Paresens that replay past sensations. Storytelling uses Paresens to explore themes such as collective memory, empathy, the limits of autonomy, and the ethics of shared consciousness.

Real-world technologies related to Paresens include telepresence, brain–computer interfaces, and social virtual reality, though none currently provide true shared sensation as described.
