then turned green. It should not have turned green unless
someone had picked the trash”. The responses received
demonstrate the need to carefully test out the best color
combinations for the utilization of alerts within this type of
drone technology, and how existing color standards (such
as traffic lights) may enhance its effectiveness. We can also
expect culture to play a significant role in the interpretation
of color in human agent/technology interaction [20]. One
would expect similar considerations to be levied towards
the design of any auditory alerts.
