We work in an open office and there's no way to tell if someone is in focus mode. People just walk up and start talking. It’s killing productivity for those of us who need longer periods of quiet. Do status indicators actually work?

We had the same issue with people tapping shoulders during deep work. We added a few visibility cues and it changed things fast. The most effective one has been this colorblind-friendly LED availability light. It lets you choose light colors that suit your vision and indicate your status clearly. It’s respectful to everyone, super easy to use, and helped us reduce unnecessary interruptions across the board. You can even sync it with calendars or task apps.
