Interaction Design

Interactions That Work

Technologically sound products are not enough if users get lost along the way. Unclear flows, inconsistent interactions, or missing feedback lead to frustration, drop-offs, and support requests.

Our interaction design experts bring together design, technology, strategy, and brand to create interactions that are not just usable, but meaningful. We make sure users can quickly find their way, act with confidence, and complete tasks intuitively.

What You Gain from Interaction Design

At Unic, we see interaction design at the intersection of UX, technology, strategy, and brand. It creates experiences that are functional, emotional, and measurably effective.

  • Better user experience: Interfaces that meet expectations and reduce friction increase satisfaction.

  • Higher conversions: Clear, purposeful interactions encourage purchases, sign-ups, and other desired actions.

  • Consistent brand experience: A unified, high-quality interface builds trust and strengthens brand connection.

  • Efficient usage: Well-designed flows reduce cognitive load, minimise errors, and lower support costs.

  • Scalability & flexibility: Good interaction design adapts to evolving requirements – across devices, audiences, and platforms.

Our Approach to Interaction Design

Concept & Prototyping

Based on your requirements and user research insights, we create initial interaction concepts and bring them to life through clickable prototypes. We refine these iteratively in reviews and workshops.

Usability Testing & Validation

Together with our UX researchers, we test prototypes with real users. We identify weaknesses and improve our concepts.

Visual Design & Refinement

We design user interfaces that are functional, engaging, and aesthetically pleasing. We focus on visual clarity, consistent use of typography and colour, and accessible contrast. Our design systems are rooted in your brand’s visual identity.

Technical Alignment & Handoff

With clear documentation, style guides, and specifications, we ensure a seamless transition to development. At Unic, interaction designers and frontend developers work side by side.

Our Core Principles for Interaction Design

At Unic, interaction designers are part of an expert network that includes UX architects, developers, project managers, and other specialists.

User Centricity

Successful interactions are grounded in real user goals, expectations, and usage contexts. They’re intuitive by nature and feel effortless to use.

Aesthetics Meet Function

We combine clarity with emotion to create designs that resonate.

Data-driven & Validated

We continuously validate our designs through usability testing, user feedback, and web analytics.

Innovation With Purpose

We integrate modern technologies such as micro-interactions, voice interfaces, or gesture control if they offer true added value.

Accessibility as a Standard

We design for all users and consistently apply WCAG standards as part of our baseline.

Long-term Partnerships

Our work doesn’t stop at delivery. We support you in continuously evolving and improving your interfaces.
