I was given a chance to contribute to new generation of Leica rangefinder, a model that would combine a time-proven physical design with up-to-date demands of the market.

The challenge became apparent immediately: modern smartphone connectivity and an abundance of user-facing information could conflict with a minimalistic two-button interaction pattern and technical limitations of the display.

The goal was to evolve the product without compromising what already worked. To retain rangefinder's compact, reliable form we needed to find a clever way to prioritise the information based on common use-case scenarios while leaving the room for personalization.

Project timeline being limited as it was, I made field research, stakeholder interviews, and canvassed hunting experts to find the best approach to structuring information, designing and placing reticle, and customizing UI.

With just two buttons, the interaction pattern had to stay simple. I defined a clear language: short presses for primary actions, long presses for secondary ones.

This interaction vocabulary was enough to create a consistent pattern across various use cases: quick access, menu navigation, Bluetooth pairing, etc.

With no reliable AI prototyping tools at the time, I recreated the interaction pattern using a game controller, mapping inputs to triggers in Figma.

This let me quickly test the learning curve, identify blind spots, and iterate before the deadline.

The initial concept assigned one button to confirm and navigate back, while the second cycled through items within the current view. Early testing quickly showed this model didn’t align with user expectations.

Participants preferred directional navigation mapped to the physical orientation of the buttons—scrolling up and down—with more disruptive actions, such as going back, assigned to a long press.

We still had time to implement our findings, so by the end of project timeline we had a solid interaction design proposal for the actual device.
