When people join a meeting in a room, the presenter shares his screen to the projector. Sometimes the
presenter is not just one‐person, other people also need to share their screen to the projector.
In this case, the people in the meeting have a chance to not know whose laptop connects to the
projector. It will cause someone to ask who is connecting to the projector now?
Our design is to build a “roject light”on the laptop. If the users start to “lide show”or “roject”on
their laptop, the project light will ON to tell everyone that I’ projecting my screen now.
