Feeling Connected


The aim with the testing was to see how children from different ages reacts to vibrations and if the vibrations can be located by using hands and/or by sitting on the blanket. To make it more pedagogical, toys and animals were placed out by the different Micro Vibrator Motors(marked red) so to make it easier to communicate which one of the toy or animal were vibrating.

non-verbal communication for infants born with Deafblindness


The purpose of this design project was to propose qualities in communication as design recommendations for developing assistive communication devices for infants with Deafblindness in order for the infant to feel connected to the context and for the caregiver to feel connected to the infant, without the need for physical contact. The design process resulted in six qualities: Direct, Spatially informative, Fluent, Individual, Turn-taking, Feedback and a final concept supporting these qualities.

The concept consists of a blanket that can connect to the microphone of a mobile phone. The mobile phone provides the blanket with the caregiver’s location (direction and distance) making it spatially informative and transfers speech directly into vibrations. The concept strives to support fluency in a conversation by using the individual prosodic qualities of rhythm and tempo in a person’s voice as input, which transfers into vibrations in the blanket as an output. As it is not a software that translates a language but transfers voice to vibrations, there are possibilities to develop interpersonal communication. Furthermore, the concept of the blanket takes the qualities of turn-taking and feedback into account to structure a frame of communication, which is needed to confirm if the information has been received and understood.


Sketches should be inexpensice, quick,  disposable, plentiful, ambiguous and lastly suggest and explore rather than confirm. This is one of many quick, inexpensive sketches that led to the final concept.


In this project, human-centered design methods have emanated accordingly to the structures of the four phases in a Double diamond process.

In the first phase of discovery, methods such as Ethnographic research were used to help understand the individual and the situation to not base anything on assumptions.

An assistive communication device was prototyped and tested with children between 1-8 years old to analyse how communication via vibrotactile stimulations was received and understood. The process and findings were recorded in written form together with suggested improvements and are published at the ACM library.


Like sketching, embodied sketching, is a method used in the early design phase but compared to sketching, includes the experience. This method helped me explore possibilities and restrictions in design concepts by probing how we experience vibrotactile stimulations by using different materials.  In order to emulate the sensation of a blanket that transfers vibrations, glass marbles were sewn into a pillowcase with an Micro Vibrator Motor(MVM) placed in each corner.


To find patterns and forge connections from research, netnography,observations and interviews, I used a method called insight mappingto help me understand and define the individual in the situation and the user needs.

Every year, six to eight people are born with Deafblindness in Sweden and there are around eighty different syndromes that can cause this disability. In today’s situation, infants born with Deafblindness do not have access to information about who and where individuals in their surroundings are unless they have physical contact with these individuals. However, it is not always possible to obtain physical contact and it is at times like these the infant can feel alone , as the world ends at the infant’s fingertips.

Establishing a form of communication can be challenging, therefore this project aims on exploring non-verbal communication so to propose  qualities in communication as design recommendations for developing assistive communication devices that can support the fluency and social interaction when physical contact is impossible.

This project was my master thesis project and was in collaboration with Certec. Certec is a part of the Department of Design Science, Factuality of Engineering at Lund University and undertakes research and education on Rehabilitation engineering and design. Certec contributed with the project suggestion:” Haptic toys or communication device".  During the project, I got to explore the challenges and opportunities of living with the impairments by conducting qualitative and quantitative research with experts from Certec, The National Resource Center for Deafblindness in Sweden, and expert users who are living with combined vision and hearing impairments.

By using the prosodic features of rhythm and tempo in a voice, one can use IoT to transfer the communicative qualities directly and fluently into vibrations, this would supports interpersonal communication in a non-intrusive way.


Result described with a storyboard.

a) Mother sharing her location (direction and distance) with her infants who is lying on the blanket, while she puts on her shoes.

b) The father connects to the blanket as well from inside the kitchen. The infant understands who they are by what they say and how they say it and where they are by clear directions of the vibrations.

And dad is over here!


Hi, Im here!
