Why the DSLIS from TECHTRON: Overcoming Real-Time Information Challenges

Navigating high-traffic transit hubs like railway stations, bus stands, and airports presents major daily hurdles for deaf and speech-impaired individuals. Critical updates—such as sudden platform changes, train arrivals and departures, delays, route diversions, and emergency instructions—are traditionally broadcast via fast-paced audio announcements.
Because these vital cues are purely auditory, the hard-of-hearing community frequently misses out on real-time awareness. This communication gap causes severe stress, confusion, and missed travel opportunities, often forcing passengers to rely heavily on manual staff assistance or fellow travellers. Techtron developed the Digital Sign Language Information System (DSLIS) specifically to eliminate these bottlenecks, granting travellers immediate access to critical transit information and restoring their independence in public spaces.

TECHTRON has developed DSLIS in alignment with the Government of India’s policies and initiatives concerning Divyangjan, the Harmonised Guidelines and Space Standards for Barrier-Free Built Environment for Persons with Disabilities.

How DSLIS Works

Multi-Language Audio/Text Input: System captures live public announcements or typed inputs from station control rooms.

AI-Powered Conversion: Advanced algorithms instantly translate multi-lingual text into standardized Indian Sign Language parameters.

Visual Avatar Display: High-definition digital avatars broadcast real-time instructions onto large strategic LED screens across platforms.

Techtron’s DSLIS utilizes an advanced multi-language artificial intelligence engine to automate visual translation seamlessly.

Multilingual Input Capture: The system accepts multi-language input from public address systems, digital control rooms, or typed text logs.

Real-Time Translation: The AI engine instantly processes and converts spoken or written text announcements (covering train timings, platform numbers, and safety alerts) into standardized sign language parameters.

Automated Visual Avatar Display: High-definition digital avatars broadcast the translated instructions in real-time onto large, strategically positioned LED display screens across platforms and stations.

Custom Announcement Flexibility: Station operators can also manually type urgent instructions—such as lost luggage or missing child alerts—save them as templates, and instantly render them into sign language.

Key Features & Capabilities

Live Transit Updates:

Real-time train numbers, arrival/departure timings, and platform indicators.

Multilingual Support:

Seamless conversion from various spoken and written languages into uniform sign language.

Custom Announcements:

Manual typing capability for emergencies, lost luggage, or children alerts with template saving

Real-Time Safety:

Immediate visual broadcast of emergency evacuation instructions and security alerts.

The system is designed to integrate seamlessly with existing Public Address (PA) systems, announcement platforms, and announcement logging infrastructure, enabling synchronized visual sign-language communication without disrupting or altering routine railway operations. This approach allows the existing railway communication ecosystem to be enhanced with an inclusive digital accessibility layer, ensuring that essential announcements and passenger information are made more accessible to the deaf and hard-of-hearing community.

How Beneficial It Is for the Hard of Hearing Community

The deployment of DSLIS brings profound transformation and empowerment to the Mook-Badhir (hard-of-hearing) community:

True Independence: It completely removes the need for manual assistance or human interpreters, allowing users to navigate public transport with dignity and confidence.

Real-Time Equal Access: Deaf passengers receive the exact same safety alerts, delays, and platform changes at the exact same moment as everyone else.

Massive Appreciation: Passengers from the community have deeply appreciated these efforts, recognizing them as a vital realization of the Prime Minister’s vision for universal accessibility, inclusion, and the Harmonised Guidelines for differently
