As I am a person who works in a home office, I am on the phone a lot and in meetings a lot. Being that I do share my home with four other family members, it is always a challenge for them to know when I am on the phone or not. One of my coworkers mentioned something called BusyLight. This is a USB device that interacts with Lync. Lync is the Online Meeting/Chat/Collaboration solution from Microsoft.
Well with the use of Lync is it not easy for my family to know if I am in a call or if I am presenting. Busylight integrates with Lync and changes as my status changes in Lync.
The solution uses a lighted wand to indicate my current situation. So when I am currently available, the BusyLight wand indicates this with a Green light outside of my office door.
Similarly if I am on a call or in a meeting it gives me the ability to let people know by indicating the wand as Red. In this case I am not likely presenting my screen.
But these two situations do not always help indicate things. For example, doing online demos or presentations require that I share my screen. Lync will automatically change my status to Do Not Disturb. In this case the light changes to a Purple.
And then lastly when I am currently away from my desk it will indicate that I am away with a yellow light.
