The New Language of Digital Touch

Virtual reality has long promised immersion, but so far, it’s mostly been visual and auditory. Touch, the most immediate of senses, has remained elusive in digital environments.

Afference, a neurotechnology company based in Boulder, Colorado, is closing that gap with a new form of neural haptic feedback. Their technology stimulates nerves directly to produce the sensation of touch, even though nothing physical is happening at the surface of the skin.

How It Works

Afference’s wearable device sends electrical signals to peripheral nerves in the arm. These signals create “referred sensations”—localized feelings of touch in parts of the hand or fingers, even though the stimulation occurs elsewhere. It’s a technique grounded in neuroscience but packaged for human-computer interaction.

Unlike traditional haptic devices that rely on mechanical actuators, Afference’s system is solid-state. With no moving parts, it’s smaller, lighter, and more energy-efficient. The device connects via Bluetooth and can integrate with VR headsets, gaming systems, and digital interfaces.

Key Features

• Referred Sensation: Triggers precise tactile perceptions remotely, adding realism to digital experiences.

• Solid-State Hardware: No motors or vibration parts—just fast, efficient nerve-level signaling.

• Bluetooth Integration: Works wirelessly with major platforms.

• Platform Compatibility: Designed to function across a range of virtual, medical, and gaming environments.

Real-World Applications

• Virtual and Augmented Reality: Enables tactile interaction in immersive simulations and environments.

• Gaming: Allows players to feel texture, pressure, and movement in-game.

• Rehabilitation and Therapy: Offers a novel interface for motor retraining and sensory feedback.

• Advanced Prosthetics: Provides real-time sensation to users of robotic or bionic limbs.

The innovation behind Afference is not just in making digital experiences feel more “real.” It’s in creating a new sensory vocabulary—one that lets machines and the human nervous system speak the language of touch.
