User Feedback
90% of users liked the image-centered tutorial, but some suggested smaller text and a more intuitive animated guide.
Too much text makes
it difficult to focus
Having lively animations
would make it easier to
understand

[Key Screen Evaluation Results]
Home Screen: Music-Centric Mode
User Feedback
It would be nice to have additional buttons, such as shuffle play and repeat,
commonly provided in music apps and the size doesn't need to be larger
than the main control buttons.
Since the album covers are visible, it feels intuitive to
understand
I'd like bigger music
control buttons

News Alerts During Stops
User Feedback
Being able to quickly switch news categories or browse and select articles from a list could be useful.
I'd like a button to change the news category.
The speed of the
moving text seems
a bit slow.

App Editing on the Home Screen
User Feedback
Initial app setup and editing on the home screen might not be intuitive.
Clear guidance on app installation, registration, and editing during the initial setup would be helpful.
Registering apps on the home screen during initial use might be difficult.
Clear instructions on
how to register apps on the
home screen would be good.
