The Tactile Internet is an emerging communication model that enables people and machines to interact across distances with near-instant response. It goes beyond video and audio communication by transmitting touch and control signals in real time. This makes it possible to perform actions remotely and receive feedback as if the user were physically present.
How It Works
The Tactile Internet relies on ultra-low latency networks and edge computing. Data must travel and return in less than a millisecond, allowing haptic feedback and control commands to stay perfectly synchronised. Using high-speed 6G networks and local processing at the edge it creates an almost delay-free link between users, machines, and digital systems.
A practical example is remote surgery, where doctors use robotic instruments that respond instantly to their movements. Similar principles apply in manufacturing, logistics, and even training environments where precision and timing are critical.
Business and Industry Applications
The Tactile Internet has wide potential in sectors where real-time responsiveness matters:
-
Healthcare: Enables remote operations and physical therapy through connected robotics.
-
Manufacturing and automation: Supports the control of industrial robots and processes from anywhere.
-
Education and training: Provides realistic, hands-on simulations for learners and professionals.
-
Entertainment and gaming: Adds touch feedback to virtual and augmented reality experiences.
-
Transport and logistics: Enables remote handling of vehicles, drones, and complex machinery.
Global and Indian Context
Worldwide, research on the Tactile Internet is advancing through 6G development projects in Europe, Japan, and South Korea. In India, the Bharat 6G Vision includes pilot work on tactile applications for healthcare, agriculture, and smart industry, supported by local innovation in edge computing and robotics.
Considerations
Real-world deployment depends on stable, low-latency networks, strong cybersecurity, and efficient energy use. Standardisation and clear governance frameworks will also be essential as the technology evolves from research to daily use.
