Some ideas we had to further develop the project if we had more time would be to do a more in depth study on how heart rate correlates with mood. We would also try to use word associations rather than explicit feeling words for the user input (for example maybe umbrella would correspond to sad). We would need to do more research into words that have actually been shown to be associated with various moods. Another idea we had was to somehow let heart rate control the beats per minute of the music or adding lights to the space that flashed in a pattern determined by the beat of the song.
