Definitions

  • the present invention relates to a method and apparatus for selecting an audio item.
  • it relates to a method and apparatus for selecting a song from a music library to generate a playlist for playback.
  • the playlists may be organised according to various attributes associated with each music item, for example, playlists may be generated by arranging the music items according to artists, genre or most frequently played etc. The music items are then grouped according to the value of an attribute and are listed. However, the lists may become cumbersome making browsing and retrieval time consuming and difficult.
  • MP3 players have become increasingly small in size making displaying and hence browsing content more difficult. Therefore, there is a demand for a user interface device which is simple, intuitive, and attractive whilst providing effective browsing and retrieval of music items.
  • the present invention seeks to provide a user interface device which is simple, intuitive, and attractive whilst providing effective browsing and retrieval of music items. This is achieved, according to one aspect of the present invention, by a method of selecting an audio item from a plurality of audio items, each audio item having a plurality of attributes associated therewith, each attribute having a corresponding attribute value, the method comprising the steps of: displaying at least a portion of a plurality of audio items along a linear path according to similarity of at least one attribute of the plurality of audio items; moving a display marker along the displayed linear path of the plurality of audio items via user input; and selecting an audio item at a closest distance to the current location of the marker.
  • apparatus for selecting an audio item from a plurality of audio items, each audio item having a plurality of attributes associated therewith, each attribute having a corresponding attribute value
  • the apparatus comprising: a display for displaying at least a portion of a plurality of audio items along a linear path according to similarity of at least one attribute of the plurality of audio items; a user interface device for moving a display marker along the displayed linear path; a processor for selecting an audio item at a closest distance to the current location of the marker.
  • the audio item may be song which is selected from a playlist which may comprise a list of related songs.
  • a plurality of items can be arranged according to their similarities to each other according to at least one attribute making browsing and retrieval of music tracks more effective.
  • the display marker is moved along the displayed linear path by a rotary user input action.
  • the rotary user interface may be a knob and turning the knob in one direction causes the marker to move in one direction and turning the knob in the reverse direction causes the marker to move in the opposite direction along the linear path.
  • the rotary interface device may be a circular path defined on a touch-sensitive screen such that tracing a finger along the circular path in one direction causes the marker to move in one direction and tracing a finger in the reverse direction causes the marker to move in the opposite direction along the linear path. Since the user interface is rotary and requires minimal space, it is particularly suited for use in small devices.
  • the linear path may represent at least one attribute of the plurality of audio items. It may comprise a first end and a second end, each end representing each extreme value of said at least one attribute.
  • the plurality of audio items may be located along the linear path such that audio items most similar to the attribute value of the first end of the linear path are located closest to the first end of the linear path and audio items most similar to the attribute value of the second end of the linear path are located closest to the second end of the linear path. This form of the linear path best applies to certain attributes such as year, tempo, location, for example.
  • the linear path may be arranged such that very different attributes may be next to each other, for example, for the attribute, genre, "pop" can be located next to "rock".
  • other methods may be used, for example, distributing a certain amount of pop songs around the pop marker (e.g. 205_2 of Fig. 2), where close to the marker are the pop-songs with certain secondary values (e.g. most played), the others are distributed in the available area according to the same specific secondary values
  • the audio items can be arranged in an intuitive manner along the linear path making locating a particular item or range of items easier. Further, due to the arrangement of the items, individual labelling of the items is not necessary as the range, i.e. an attribute value is labelled enabling the display to be reduced and reducing clutter on the display making it easier and quicker to read. Furthermore, it allows searching and playing in a general direction rather than focusing on a specific track.
  • the currently selected audio item may be highlighted so that the user is provided with a clear indication of which of the items is currently selected.
  • the method further comprises the steps of: as the marker is moved along the linear path and the currently played, selected audio item is no longer closest to said marker, select the audio item now closest to the new location of the marker, stop playing said currently played, selected audio item, and start playing said newly selected audio item.
  • a tuning-type of interaction is achieved providing the user with an immersive music experience having music played continuously which also provides the user with feedback by playing the music item which is closest to the marker as it is moved and hence the item that would be selected by the marker in that position.
  • the at least one attribute to be represented by the displayed linear path may be selected and changed by the user and the display may be changed to the linear path of the selected at least one attribute and consequently changing the display of at least a portion of said plurality of audio items according to similarity of the plurality of audio items to the selected at least one attribute.
  • playing the currently selected audio item will comprise playing the audio item now closest to the marker on the new displayed linear path.
  • the current playing audio item continues to play, while the linear path around it changes.
  • the location of the current playing audio item can change.
  • the next audio item will be in relation to the new attribute (for example, the user is currently playing a "pop" song in Genre path, the next song could be a similar "pop” song. However the user changes the linear path (attribute) to "year”.
  • the current "pop" song is from "1992".
  • the next song could be a song of any genre, e.g. "jazz” but from the "year” of "1992"
