Abstract

A system (100) for categorizing songs on a physiological effect of the song on a user includes a storage medium (120) for storing songs, a memory (140) for storing for a predetermined physiological state of a user an associated predetermined first selection criterion, a rendering system (150) for rendering songs, and a sensor (130) for determining a biological parameter of the user representative of a physiological state of the user. A processor (110) tests a selected song for a physiological effect. The selected song is rendered a plurality of times. Each time, the sensor obtains at least one measurement, and the first criterion is used to determine a respective indicator indicating whether rendering of the song has a positive effect. Next, a second predetermined criterion is used to, based on a plurality of the determined indicators, determine a suitability of the song for bringing the user closer to the predetermined physiological state.

Claims

1-18. -18. (canceled)

19. A system (100) for categorizing songs based on a physiological effect of the song on a user;

the system including;

a storage medium (120) for storing a plurality of songs;

a memory (140) for storing an associated predetermined first selection criterion for at least one predetermined physiological state of a user, said memory also storing for each of at least one predetermined physiological state, an associated playlist of songs for bringing the user closer to a particular predetermined physiological state;

a rendering system (150) for rendering songs retrieved from the storage medium;

a sensor (130) for determining a biological parameter of the user representative of a physiological state of the user; and

a processor (110) configured for;

repeatedly causing the selected song to be rendered,

using the sensor to obtain at least one measurement during said rendering,

using the first predetermined criterion to determine, in dependence on the measurement, a respective indicator indicating whether rendering of the song has a positive effect on bringing the user closer to the predetermined physiological state; and

using a second predetermined criterion to determine, based on a plurality of the determined indicators for the song, a suitability of the song for bringing the user closer to the predetermined physiological state.

20. A system as claimed in claim 19, wherein the processor is programmed to use the sensor at least twice during the rendering of the song to obtain at least two time-sequential measurements of the biological parameter;

the first criterion being dependent on a change of the at least two measurements.

21. A system as claimed in claim 19, wherein the sensor is a brain-wave sensor for determining a frequency of brainwaves of the user.

22. A system as claimed in claim 19, wherein the sensor is of a contact-free type.

23. A system as claimed in claim 20, wherein the predetermined physiological state is asleep and the first criterion includes whether a brainwave frequency has decreased during rendering of the song.

24. A system as claimed in claim 20, wherein the predetermined physiological state is alert and the first criterion includes whether a brainwave frequency has increased during rendering of the song.

25. A system as claimed in claim 19, wherein the first criterion is dependent on an actual physiological state being measured during the rendering

26. A system as claimed in claim 20, wherein the first criterion includes whether the measured physiological state is the predetermined physiological state and whether no substantial change has been detected between the at least two measurements during the rendering.

27. A system as claimed in claim 19, wherein the second criterion includes that a predetermined successive number of times during the rendering a same song all respective indicators have indicated that rendering of the song has a positive effect on bringing the user closer to the predetermined physiological state.

28. A system a claimed in claim 19, wherein the memory is arranged to store for the predetermined physiological state an associated playlist of songs for bringing the user closer to the predetermined physiological state.

29. A system as claimed in claim 28, wherein the processor is programmed to, based on the determined suitability, determining whether the song should be added to and/or maintained on the playlist.

30. A system as claimed in claim 28, wherein the memory includes for songs on the playlist an associated suitability indicator;

and wherein the processor is programmed to determine a relative rate of rendering of a song on the playlist in dependence on the associated suitability factor.

31. A system as claimed in claim 28, wherein the memory includes a candidate playlist of songs being tested for acceptance on the playlist;

the candidate play-list including for songs on the candidate playlist associated information including at least the indicator indicating whether rendering of the song has a positive effect on relaxing the user.

32. A system as claimed in claim 21, wherein the processor is programmed to use the brain-wave sensor to determine at least one of the following physiological states:

the user is falling asleep,

the user is asleep,

the user is awakening,

the user is alert;

and, in response to determining so, stop rendering of songs or start rendering of songs.

33. A system as claimed in claim 19, wherein the system includes a user interface for enabling a user to select the song for testing.

34. A system as claimed in claim 19, wherein the rendering system includes speakers for generating spatially localized sound, such as an earphone, headphone or sound-beamer.

35. A method of categorizing songs on a physiological effect of the song on a user;

the method including;

repeatedly causing the selected song to be rendered (210) by a rendering system,

using a sensor to measure (210) at least once during the rendering of the song a biological parameter of the user representative of a physiological state of the user,

using a first predetermined criterion (220) associated with a predetermined physiological state of a user to determine, in dependence on the measurement, a respective indicator indicating whether rendering of the song has a positive effect on bringing the user closer to the predetermined physiological state; and

using a second predetermined criterion (240) to determine, based on a plurality of the determined indicators for the song, a suitability of the song for bringing the user closer to the predetermined physiological state.

36. A computer program product for causing a processor to perform the method of claim 35.
