I’m proud to present LightLock to you — a concept I helped design for FitPhone, a project by Fontys Eindhoven focused on healthier smartphone use.

Together with my team, we developed LightLock to gently guide university students toward more mindful screen habits. The idea is simple: by linking smartphone use to ambient light levels, we nudge students to reduce usage in study environments. It’s a subtle social intervention, but one rooted in smart behavioural design.

You can watch an explanatory video by clicking here. Not enough for you? Or do you want to see all the results from our design activities, survey, and user test? Read the full report just below!

As a bonus? I personally later wrote a follow-up report focused on improving LightLock’s social and environmental impact. That process led to a radical rethinking of the lighting system—one that made it both more sustainable and socially sustainable. If you’re interested, have a look at the report below!
