+# Greeting Selection: Greetings among humans
+* Greetings are the means of initiating and closing an interaction.
+* We desire that robots be able to greet people in a similar way to humans.
+* For this reason, understanding current research on greetings in sociological studies is necessary.
+* Moreover, depending on cultural background, there can be different rules of engagement in human-human interaction.
+
+# Greeting Selection: Solution for selection
+* A unified model of greetings does not seem to exist in the literature, but a few studies have attempted a classification of greetings.
+* Some more specific studies have been done on handshaking.
+
+# Greeting Selection: Classes for greetings
+* A classification of greetings was first attempted by Friedman based on intimacy and commonness.
+* The following greeting types were mentioned: smile; wave; nod; kiss on mouth; kiss on cheek; hug; handshake; pat on back; rising; bow; salute; and kiss on hand.
+*  Greenbaum et al. also performed a gender-related investigation, while [24] contained a comparative study between Germans and Japanese.
+
+# Greeting Selection: Factors on Classification
+* 'terms'  : same terms with different meanings, or different terms with the same meaning.
+* 'location' : influences intimacy and greeting words. (private or public)
+* 'intimacy' : is influenced by physical distance, eye contact, gender, location, and culture. (Social Distance)
+* 'Time' : time of the day is important for the choice of words.
+* 'Politeness', 'Power Relationship', 'culture' and more.
+
+# Greeting Selection: Factors on Classification

+* the factors to be cut are greyed out.
+
+# Model of Greetings: Assumptions (1 - 5)
+* The simplification was guided by the following ten assumptions.
+* Only two individuals (a robot and a human participant): we do not take in consideration a higher number of individuals.
+* Eye contact is taken for granted.
+* Age is considered part of 'power relationship'
+* Regionality is not considered.
+* Setting is not considered
+
+# Model of Greetings: Assumptions (6 - 10)
+* Physical distance is close enough to allow interaction
+* Gender is intended to be a same-sex dyad
+* Affect is considered together with 'social distance'
+* Time since the last interaction is partially included in 'social distance'
+* Intimacy and politeness are not necessary
