With Joan Home, you could attach a purpose-built tablet to a wall and have that tablet display upcoming meetings for a room. That tablet was e-ink only, so battery life wasn’t an issue. And imagine there was a piece of companion hardware that allowed you to, with a single tap, book or release a room or reserve a room for a specific time.

This smart gadget connects to your calendar, displaying calls and meetings. So your family, friends, roommates—anyone around—know not to bother you when you’re busy. This helpful gadget mounts magnetically outside your door or near your desk. And it makes it clear to others when you’re currently working.

In fact, the Joan Home displays your current availability as either Free or Busy, and the status changes automatically. Moreover, you can ask this office availability calendar to display your timetable for the day, so everyone around knows when you’re free for lunch, chores, or chats.

Furthermore, you can choose to display other information when you aren’t working, such as general information or photos.
