29. Personal Characteristics
◦ Locus of control
▫ "The extent to which people believe the have power over events in their lives"
Fourier
◦ Need for cognition
▫ "Tendency for an individual to engage in, and enjoy effortful cognitive activities"
Cacioppo
◦ Visualisation Literacy
▫ "The ability to interpret and to make meaning from information presented in the
form of images and graphs" Boy
◦ Visual Working memory
▫ "The part of our cognitive system that is responsible for short-term holding of
information for further processing" Corsi
◦ Musical Experience
▫ "The construct that can refer to musical skills, expertise, achievements, and
related behaviours across a range of facets" Gold-MSI
29
34. Measurements perception
◦ Recommender effectiveness
▫ The songs recommended to me match my interest
▫ The recommender helped to find good songs for my playlist
◦ Good understanding
▫ I understood why the songs were recommended to me.
▫ The information provided for the recommended songs is sufficient to make a
decision
▫ The songs recommended to me had similar attributes to my preference
◦ Trust
▫ I trust the system to suggest good songs
◦ Novelty
▫ The recommender system helped me discover new songs
◦ Use intention
▫ I will use the system again
◦ Satisfaction
▫ Overall, I am satisfied with the recommended system
◦ Confidence
▫ I am confident about the playlist I have created
34
35. Measurements interaction
◦ Nb_slider
▫ The number of times the participant used a slider
◦ precision
▫ Songs liked / songs recommended
◦ Nb_play
▫ Total number of songs played
◦ Nb_why
▫ Number of explanations clicked open
◦ Duration_why
▫ The amount of time the explanation is open
