  • the thickness of the trajectory will e.g. depend on the pressure with which the input is performed. This case is schematically shown for the trajectory C3 in Fig. 2.
  • the first and last sections of the trajectory are performed with lower pressure, while the intermediate section is performed with increased pressure (schematically indicated by the differing thickness of the trajectory C3).
  • the dynamic effects can be chosen such that the more pressure the user exerts during input the more dynamics are selected, while with less pressure exerted less dynamics are selected.
  • trajectory can be additionally or alternatively exploited.
  • One further example is the speed with which the trajectory is drawn by the user. For example, a high speed can be used to select more dynamics and a lower speed to select less dynamics. The speed can e.g. be detected with suitable run-time algorithms.
  • the at least one further feature is determined and exploited for determining a further property of the second media object
  • the at least one further feature can e.g. also be used for selecting a further property of the first media object (such as e.g. the volume in the case of audio files being the first media objects).
  • audio files have been described as specific first media objects and light effects have been described as specific second media objects, the invention is not limited to this combination and other combinations of first and second media objects as defined in the introductory portion shall also be encompassed.
  • first and second media objects to be presented simultaneously has been described with respect to the embodiments, a combination of more (different) media objects to be presented simultaneously is possible.
  • tactile effects can be added as third media objects to be presented together with the first and second media objects.
  • these further media objects are also added to the playlist by exploiting further features of the trajectory input by the user.

Abstract

L'invention concerne un procédé pour créer une liste de lecture comprenant des premiers objets multimédia, et des seconds objets multimédia destinés à être présentés simultanément. Le procédé comprend les étapes suivantes: chargement d'une pluralité de premiers objets multimédia à partir d'une base de données (S1); attribution de coordonnées aux premiers objets multimédia (S2); attribution de coordonnées aux seconds objets multimédias (S3), création d''une représentation au moins bidimensionnelle représentant les premiers objets multimédias et les seconds objets multimédias correspondants (S4); réception d'une entrée utilisateur sous forme d'une trajectoire (C1, C2, C3, C4) dans la représentation au moins bidimensionnelle (S5); et création d'une liste de lecture contenant des ensembles consécutifs de combinaisons de premiers objets multimédias et de seconds objets multimédias destinés à être présentés simultanément sur la base de la trajectoire (S6).
