Motivation – Elicitation of preferences is crucial in negotiation support. This is a non-trivial task which could be supported by computers. Research approach – Experiment in which 32 participants have to order holidays using different preference elicitation techniques including a navigational task and affective scoring. The results were used as input for a lexicographic ordering algorithm. Findings/design – Traditional property rating approach seems most preferred by the participants and resulted in one of the best orderings of the outcomes space to match their preferences and at least when using the lexicographic algorithm. Originality/value – The elicitation process is approached from an algorithmic perspective as well as from a user-centred perspective for both navigation and affective attitude. Take away message – A multi-angle approach gives a richer understanding of the process of preference elicitation.
