add sentiment indicators to skype calls
It would be awesome if Skype could tell you how the people on a call are feeling, particularly if you are not using video, or for users who may have difficulty reading the emotions of others.
You could add a simple button to the skype call window next to the screen sharing and hang up buttons. When the user clicks it, three colored circles appear: a yellow smiley face, a grey face neither smiling nor frowning, and a blue frowning face. As soon as a user clicks one of these, everyone else on the call sees the appropriate emoji appear below their name/video. You could use this data to begin training an AI algorithm to automatically identify the sentiment of people's voice and video, and eventually remove the need for the button.
