  Charisma is considered as one's ability to attract and potentially also
influence others. Clearly, there can be considerable interest from an
artificial intelligence's (AI) perspective to provide it with such skill.
Beyond, a plethora of use cases opens up for computational measurement of human
charisma, such as for tutoring humans in the acquisition of charisma, mediating
human-to-human conversation, or identifying charismatic individuals in big
social data. A number of models exist that base charisma on various dimensions,
often following the idea that charisma is given if someone could and would help
others. Examples include influence (could help) and affability (would help) in
scientific studies or power (could help), presence, and warmth (both would
help) as a popular concept. Modelling high levels in these dimensions for
humanoid robots or virtual agents, seems accomplishable. Beyond, also automatic
measurement appears quite feasible with the recent advances in the related
fields of Affective Computing and Social Signal Processing. Here, we,
thereforem present a blueprint for building machines that can appear
charismatic, but also analyse the charisma of others. To this end, we first
provide the psychological perspective including different models of charisma
and behavioural cues of it. We then switch to conversational charisma in spoken
language as an exemplary modality that is essential for human-human and
human-computer conversations. The computational perspective then deals with the
recognition and generation of charismatic behaviour by AI. This includes an
overview of the state of play in the field and the aforementioned blueprint. We
then name exemplary use cases of computational charismatic skills before
switching to ethical aspects and concluding this overview and perspective on
building charisma-enabled AI.
