Project Outline
• The Echo Nest has developed a next-generation music
recommendation engine
• Extends current API capabilities to location and activity
sensing on smartphones
• A prototype has been built
• Turn that prototype into a product

UX Testing in Sprint Five
• Human-centered design process

Project Limitations
• User testing was unavailable prior to sprint five
• UX test subjects were a convenience sample
• API was not available for UX validation
![Page 5: “Zero Button” Music Player · UX Testing in Sprint Five ... • Minimum viable interface. Prototype One. Prototype One. Prototype Five. Findings • Current app playlists are](https://reader035.vdocument.in/reader035/viewer/2022062317/5f0300d47e708231d4070f45/html5/thumbnails/5.jpg)
Research Scope
• Use of current music apps
• Perceived value of recommendations
• Willingness to share data (privacy concerns)
• System image v.s. user model
• Minimum viable interface

Findings
• Current app playlists are difficult to maintain
• Competitive products leave gaps in user needs
• Users are skeptical of recommendation tools
• Skepticism leads to reluctance to share data
• Reluctance can be mitigated

Data Sharing
• Willingness to share = (perceived value / privacy
concern)
• Users need to understand the value
• System image must be framed correctly
• App name, marketing language, in-app help
• Soft-pitch of permission requirements upon install

User Interface
• Core music controls easily understood
• Playlist management screen functions clear
• Actual functionality of „venues‟ unclear
• Dimension „tuning‟ did not match to user model

Discussion
• After initial prototypes, team re-scoped
• Simplification of UI = need for highly effective AI
• And, highly developed understanding of user needs
• Better understanding of API performance needed
• More foundational research recommended
• Team de-emphasized visual/interaction design efforts

Adjacent ideas
• Use iBeacons to identify nearby users and generate
shared playlist
• Use Songkick API to seed locally performing acts in
playlist

Recommendations
• App name and collateral should strongly frame the
unique values of the app
• Personas should be developed to help clarify
motivations/barriers to use
• Ethnographic study should be performed to identify
gaps to be filled in daily music-listening routines

Recommendations
• Conceptual interface designs should be explored to lead
direction of wireframe development
• Key performance indicators should be used to create
success metrics for „sensor-enhanced‟
recommendations
• User testing should be restarted and continue
throughout the design/development process
