Systems and methods are described to monitor and record user context and engagement with music. In an exemplary method, a user device receives an audio input of a user's audio environment, for example through a microphone. From the audio input, a song playing in the user's audio environment is identified by a user device. This may be done by consulting a database of audio features. The user device determines the user context and/or a user's level of engagement with the song. The context may include the time and location at which the song was playing. The level of engagement may be determined by monitoring whether, for example, the user danced or otherwise moved to the song, whether the user sang along to the song, and/or whether the user turned up the volume of the song.

In-ear sound pressure level, SPL, is determined that is caused by output audio being converted into sound by a headset worn by a user. The in-ear SPL is converted into a sound sample having units that are suitable for evaluating sound noise exposure. These operations are repeated to produce a sequence of sound samples during playback. This sequence of sound samples is then written to a secure database. Access to the database is authorized by the user. Other aspects are also described and claimed.

A digital signal processing method for ambient sound acoustic dosimetry. Strength of a microphone signal generated by a watch worn by a user is determined and converted into a sound sample having units for sound noise exposure. This is repeated multiple times to produce a time sequence of sound samples that is written to a secure database access to which is authorized by the user. Other aspects are also described and claimed.

A computer-implemented method receives, from a user device, user ID information, a target emotional state value, and target time information, acquires personal physiological rhythm data of a user including a plurality of emotional state values from a data storage, acquires present time information, determines a present emotional state value from the plurality of emotional state values, calculates a difference value between the present emotional state value and the target emotional state value, estimates a spontaneous variation of an emotional state value based on the physiological rhythm data, compensates the difference value by the spontaneous variation, selects a content that is expected to cause the emotional state value of the user to change by the compensated difference value, and provides the selected content to the user device.

The present disclosure relates to a system and a processing method in association with the system for customizing audio experience. Customization of audio experience can be based on derivation of at least one customized audio response characteristic which can be applied to an audio device used by a person. The customized audio response characteristic(s) can be unique to the person.

Devices and methods to track contact between persons using acoustic voiceprint identification from stored audio signals are presented herein.

A system and method for controlling a non-tactile device including a receiving device configured to receive signals corresponding to a user's brain waves or movements, the brain waves or movements corresponding to a series of directional intentions, the intentions defining at least one line pattern, a processor configured to process the at least one line pattern, each of said at least one line patterns associated with an action of the device, and output a control signal to the non-tactile device related to the action.

Apparatuses, systems, and methods of the present disclosure may provide access security in a process control system. For example, current biometric data representative of a user may be acquired and compared to stored biometric data representative of previously identified users. Access to the process control system may be authorized when the current biometric data matches stored biometric data.

A multisensory index system and an operation method thereof are provided. The multisensory index system is configured to derive quantitative parameters and qualitative parameters associated with an auditory sense and a tactile sense, and generate a multisensory index by analyzing a correlation between the quantitative parameters and the qualitative parameters associated with the auditory sense and the tactile sense.
