hint. human interaction design.

In the progressive technologization of the product world, we consider ourselves intermediaries between humans and technology. We consider acceptance and trust as key for successfully establishing new technologies in our everyday life. Our goal is to reach these through human-centered, intuitive, and immediate products.

Valentin Lindau

Valentin is a product & interaction designer. He has more than 5 years of experience and specializes in designing household appliances, consumer electronics and robots. In recent years he has worked for leading international brands & innovative startups. His roots are in classic industrial design, his heart beats for designing physical products with strong digital components and autonomous technology.

At hint he is responsible for physical prototyping and leads hardware and strategy projects.

Autonomous products

Autonomously moving products, pose new challenges with regards to their outer design, and require new ways of communication and interaction. A robot must not be a black box, it should communicate with its environment and its users. Designing a dialog with them is an essential part of our work – experienceable at our cobot Sweep:

Post-Screen User Experiences

We take human perception as a starting point and combine principles of interpersonal communication and interaction with interaction on graphical user interfaces. This results in intuitive interfaces and user experiences for the handling of autonomous products.


We make use of perception, empathy, and body language, so technology can be adapted to humans.


Our interactions are simple and intuitive. We learn from acquired patterns of social behavior.


The interaction with technology is direct. We try to reduce screen interactions to a minimum.

Bodylanguage for Autonomous Technology

Bridging the Gap

We are hint, a young product and interaction design team from Berlin. Our mission is to make the use of new technologies more human and intuitive. We share a common fascination for designing user interfaces and experiences for robots and autonomous products. This is where the smartphone reaches its limits as an all-round solution. It is therefore time to work on more immediate and humane ways of interaction.

In 2017, we discovered that the majority of autonomous products on the market hardly communicate with their environment. It felt strange and unnatural to use or observe them. Their behavior was mostly just a random product of engineering. This is not how we wanted to imagine the future, in which we will be surrounded by more and more robots. That’s why we founded hint in 2018, creating a place where the interaction between humans and robots is consciously designed. We rely on empathy: Because humans react empathetically to anything that moves by itself – regardless of whether it is a living being or a machine.

With this innovative approach to interaction design, we were accepted into an EU design-in-tech accelerator, where we were able to work on our studio profile and first projects. Since then we have been developing innovative user interfaces and experiences for all kinds of robots - from vacuum cleaners to professional cobots. We have already convinced leading international brands and start-ups to work with us on exciting projects.
