App Design Sketches -- Multiple people controlling one Bluetooth Speaker

     I could not for the life of me focus on math homework, so I decided to tackle a major UI problem: interface between a Bluetooth speaker and multiple phones. A portable speaker has to  be laboriously paired and unpaired for the speaker to switch users. Though this problem is mainly hardware, there are ways that Bluetooth incompatibilities can be worked around. This UI sketch shows how this might be done, following Jawbone's app design language.
