Improving user intput interface

Once we finished our initial system paper we could consider an improvement of the input interface.

So far we our input interface consists of buttons to contribute in the crowd. An improvement would be to use the microphone as input. But instead of directly sending the sound as when talking, we could have a separated microphone mode that is mutually exclusive to the regular audio mode. With this the user would be able to mute the regular voice mode, but can unmute our crowd laughter mode. Then we use the microphone to detected laughters, clapping, etc. on the client. This information can then processed with the same workflow as before when hitting the buttons.

• Buttons
• Microphone
• Camera

In our system paper we use the most simple one, namely the Buttons
