07 Attitudes The autonomous machine needs to be able to express attitudes based on context. As machines taking on a more active role when interacting with humans, their capabilities of express attitudes through communications become more important. Correct attitudes can avoid miscommunications and certainly create more vivid and engaging interactions.
"Many aspects of natural language communication cannot properly be understood without taking the accompanying affect expressions into account."[13] Imagine in a scenario where an autonomous machine is trying to attend an emergency. In such case, it would want express a pressing and alerting attitude so people can make way for it to pass. In another case, if machine has made a mistake during an interaction, apologetic attitude would communicate that the machine is aware of its mistake and relief users’ frustrations.
