Emotion-aware music, designed for human understanding.

Facial expression is an uncertain signal. I designed the experience that turns it into a clear, supportive listening choice: synthesizing research into a four-stage journey, designing feedback and explanation states, and helping integrate them into a working research prototype documented in a co-authored IEEE paper.

Problem

Music recommendations rarely reflect a listener's immediate context, and an expression signal alone can be wrong.

My role

UX research synthesis, journey architecture, feedback states and prototype integration support.

Deliverable · 2022

One working research prototype and a co-authored 2022 IEEE MysuruCon paper.

Design challenge

An uncertain signal.
A clear listening choice.

How might we turn an uncertain expression signal into a clear, supportive and understandable listening decision?

A facial expression is not a feeling. The experience had to present the system's reading as an interpretation, keep each step legible, and leave the listener with a choice, without implying clinical value or that emotions were definitively inferred.

My contribution

My focus within the team:

  • Research-to-UX synthesis: translated emotion and music-therapy literature into listener needs and design principles.

  • Mapped the capture → recognize → curate → recommend journey and its system states.

  • Designed feedback and explanation states so a prediction reads as an interpretation, not a verdict.

  • Supported integration of recognition output into the interactive prototype.

  • Documented design decisions in the jointly published paper.

Listening journey

From emotion cues to an intuitive listening experience.

  1. 01Capture

    Expression input

    Input: facial expression

    Webcam expression input, requiring clear user expectations.

  2. 02Recognize

    Interpret the input

    Output: expression prediction

    An expression prediction provides the input for playlist curation.

  3. 03Curate

    Playlist mapping

    Mapping: emotion to playlist

    Research-informed playlists connect detected expressions with listening options.

  4. 04Recommend

    Music recommendation

    Result: listening option

    Present a clear music recommendation and understandable next action.

Design decisions & engineering handoff

Three design decisions

Feedback clarity, intentional curation and a focused interaction path shaped the experience.

01

Make feedback and system states clear.

Connect expression prediction to playlist mapping so the listener can understand why a recommendation appears.

Trade-off

Keep explanations concise and frame the detected expression as an interpretation.

02

Curate with a listening intention.

Music-therapy literature informed playlist choices beyond simply matching music to a detected mood.

Trade-off

The curation rationale is literature-informed; listening benefit would need a separate user study.

03

Guide one interaction at a time.

Separate capture, interpretation, curation and recommendation into a focused path toward a listening option.

Trade-off

Prioritize the core journey in the research prototype, with consent controls and manual choice as next design priorities.

Prototype implementation

From research to functioning prototype.

Research & definition

Emotion-recognition and music-therapy literature helped frame the problem: translate a technical prediction into a useful listening experience.

Flow, UI & prototyping

The four-stage journey connected expression capture, system feedback and playlist delivery in an interactive flow.

Integration, evaluation & publication

Recognition output was connected to recommendations in a working prototype. The team evaluated the recognition system and documented the work in a co-authored IEEE paper.

Limits & what I'd improve

Keep the listener in control.

The 2022 evaluation measured recognition-model performance only. Usability, trust and listening benefit were not tested, so the priorities on the right are what I would design and validate next​—⁠not features of the original prototype.

Next steps · if redesigned today

Priorities for a future iteration.

  • Consent and privacy: explicit opt-in before webcam capture, with visible capture state.
  • User control: a manual override when the prediction doesn't match how the listener feels.
  • Trust feedback and usability research with diverse listeners, measured separately from model accuracy.
