MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202521124610 A) filed by Siddharth Bhagwan Bhorge; Ashwinee Pravin Pulujkar; Vivek Rajendra Shejole; Shantanu Suhas Khopade; Mohit Bhatu Shinde; and Aditya Susheel Mandke, Pune, Maharashtra, on Dec. 10, 2025, for 'video call intercom system with real-time sign language recognition and tactile feedback.'
Inventor(s) include Siddharth Bhagwan Bhorge; Ashwinee Pravin Pulujkar; Vivek Rajendra Shejole; Shantanu Suhas Khopade; Mohit Bhatu Shinde; and Aditya Mandke.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The invention introduces an integrated and cost-effective video call intercom system designed to enable accessible, real-time communication between sign-language users and verbal communicators. The system incorporates a vision-based sign language recognition module that operates using standard camera input to extract hand landmarks, generate feature vectors, and convert gestures into text without requiring specialized hardware. Alongside this, a browser-native speech-to-text module provides rapid transcription of spoken communication, allowing seamless bidirectional translation between sign language and speech. A microcontroller-based tactile alert mechanism, utilizing a vibration motor and PWM-driven patterns, delivers reliable non-visual notifications for incoming calls and messages. This ensures that users with hearing impairments receive timely alerts even when visual cues are missed. The system operates entirely through a web-based architecture, enabling compatibility across common devices while reducing installation complexity and hardware dependency. By combining computer vision, speech processing, web communication capabilities, and tactile feedback within a single platform, the invention addresses limitations in current communication systems such as insufficient sign-language support, reliance on interpreters, and the absence of non-visual alert mechanisms. The modular and scalable design allows deployment across homes, healthcare settings, educational institutions, workplaces, and public service centres. The invention significantly enhances communication accessibility and inclusivity for individuals with hearing impairments."
