Researchers are working to revolutionize orchestras through wearable computing devices such as Google Glass:

• In the future instead of looking at a sheet of music on a stand, members of an orchestra may wear augmented glasses that scroll the notes that they should be playing across the screen.
• The notes might even be animated or shaped differently to convey more information to the musician about how the note should be played.
• The conductor’s point of view could be live-streamed so that members of the group can see where the conductor is looking and which members are currently playing.
• There are still challenges such as the issue of video lag – which can throw off the timing of the entire orchestra.
