Winner, IIC Bharat 1.0 (2023) · Indian patent No. 591733, granted June 2026

Problem: For Deaf users, the hardest part of communication often isn't the language gap, it's the moment itself, conversations that move faster than lip-reading, interpreters, or captions can keep up with.

Approach: Research into different Deaf experiences and real-life communication scenarios, leading to a haptic device that translates speech into phonetic tactile feedback, a language you learn through touch.

Outcome: The concept won IIC Bharat 1.0 (2023) and was later granted an Indian patent (No. 591733, June 2026).

02 / PROBLEM STATEMENT

When conversation moves faster than access.

Real-time communication can become inaccessible for Deaf individuals when spoken language has no immediate visual or interpretive alternative. This creates a gap not just in hearing, but in participating in the moment.

The challenge isn't simply not hearing. It's the possibility of missing information, context, or a response in the moment, while the conversation continues around you.

03 / EXISTING SOLUTIONS

When conversation moves faster than access.

Before asking what hEar should do, we first looked at what technology already makes accessible. The landscape fell into three broad categories:

01
Hearing-assistive tech (hearing aids, cochlear implants, FM/loop systems) helps people with residual hearing, but not profound deafness.
02
Communication tech: AI captioning, vibrotactile wearables, sign-to-speech gloves, video relay, creates alternative channels for language access.
03
Alerting & haptic tech turns sound into touch: vibrating wristbands for alarms/doorbells, and emerging tools like Ontenna and haptic vests that let users feel sound and music.

But mapping these solutions revealed a gap…

04 / MARKET RESEARCH

68 Million

The National Association of the Deaf estimates 18 million Indians have hearing loss, while the Indian Journal of Otology suggests it's closer to 63 million. WHO considers severe hearing impairment, yet in India, only those with 40 percent disability or above 60dB loss qualify as hearing handicapped.

31%

feel they are treated differently because of their deafness, hearing loss and tinnitus

33%

of people who are deaf avoid social situations because they find it difficult to communicate

68%

of people with hearing loss feel isolated at work as a result

99%

of hearing-impaired people are either uneducated or drop out after Class VI or VII, because they are not able to cope

How big is the gap?

Hearing loss is one of the most widespread sensory impairments worldwide. In India alone, approximately 63 million people have been estimated to live with significant auditory impairment, around 6.3% of the population.

And the scale is only growing. By 2050, nearly 2.5 billion people globally are projected to experience some degree of hearing loss, with more than 700 million requiring hearing rehabilitation.

05 / PRIMARY RESEARCH

What does the gap look like in real life?

To move beyond statistics and existing solutions, we went into the environments where communication happens every day, field visits to restaurants employing Deaf staff and a school for Deaf students, to ground design decisions in lived experiences rather than assumptions.

  • Communication barriers followed people everywhere, at work, school, and social interactions, not as isolated incidents.
  • Safety was a recurring concern. Alarms and auditory cues could easily go unnoticed.
  • Isolation extended beyond individual settings, shaping how Deaf individuals connected with the broader community.
  • Misunderstanding had tangible consequences when instructions or signs were misinterpreted.
  • In special schools, sign language was foundational to effective communication.

06 / EMPATHY MAP

Empathy map of Deaf users

The hardest part wasn't the language. It was the moment.

Mapping what users said, thought, felt, and did revealed a consistent thread: the anxiety of being misunderstood in the moment outweighed concerns around vocabulary or fluency itself.

The problem wasn't simply knowing the language. It was being able to keep up with the conversation, understand what was happening, and respond with confidence, while it was happening. This shifted our design priority toward two things: Speed. Clarity.

07 / AFFINITY MAP

Affinity map grouping research themes

Different situations. The same underlying needs.

Safety, being able to perceive warnings and important auditory cues.

Workplace inclusion, understanding instructions and participating independently.

Education access, receiving and interpreting information without communication becoming a barrier.

Social confidence, engaging without the constant fear of misunderstanding.

Across all four, one need kept resurfacing: communication had to happen in real time, and without demanding constant effort.

08 / USER PERSONAS

There isn't one Deaf experience.

Our research revealed that the Deaf and hard-of-hearing community is far from homogeneous, from first-language sign users to people newly navigating hearing loss. Different starting points. Different needs. One shared challenge: being able to participate in communication as it happens.

09 / TOWARDS THE SOLUTION

So, what if language could be felt?

Our research pointed toward a different way of approaching real-time communication: instead of trying to make sound more accessible, what if spoken language could be translated into touch?

That idea became hEar, a wrist-worn tactile communication device designed to convert spoken language into phonetic vibration patterns that can be perceived through the body.

  • Scientifically curated patterns, validated principles for effective vibration patterns.
  • User-centric, development centers on identified user requirements.
  • Ergonomic design, fits on the wrist, forearm, and neck.
  • Multi-purpose, versatility addressing various user needs.
  • Portable and stylish, blends with daily attire, function and aesthetics.

10 / WORKING EXPLAINED

Turning speech into sensation

An effective device designed to empower individuals with hearing impairments. Our device leverages cutting-edge technology to translate sound into patterns of vibration on the skin, opening a new world of sensory perception.

Voice → Text → Phonetics → Vibration → Touch

Working Explained

01
Voice to Text Conversion: The device converts spoken language into text.
04
Tactile Format: Users feel the vibrations on their wrist, resembling a watch.
02
Phonetic Conversion: It further converts the text into phonetic characters.
05
Ambient Sound Alert: The device includes a sound sensor that uses LEDs to alert the user in the presence of ambient sounds.
03
Vibration Feedback: Each phonetic character corresponds to a unique pattern and is conveyed to the user via six vibrating motors.

This comprehensive manual elucidates the process of converting phonetics into vibration patterns through meticulous numerical assignments, a valuable reference for a thorough understanding of the transformation.

12 / THE COMPANION APP

A language you can learn through touch

We've developed a specialized application for deaf children, seamlessly integrated into their tailored curriculum. This addition reduces cognitive fatigue, streamlines communication, and has the potential to enhance the learning experience while boosting their confidence and self-esteem.
