Infinitely Scrolling Carousel

[chriscm2006]

A widget that shows a collection of views scrolling across the screen for users to explore a potentially infinite set of items.

Application Examples

• Facebook's exploring new friends implementation.
• Scanning through photos of a hotel room.

How Carousels Behave for Non AT Users

A typical user interacting with an Carousel Widget comes to the widget to explore. It typically takes up a third to a half of the screen. Users can then:

• Swipe Right/Left to explore items in the carousel
• Optional: interact with an individual item
• Optional: Toggle Items on or off.

Accessibility Concerns

1. TalkBack: Communicating the size/number of elements in the carousel.
2. TalkBack: Communicating current position within the carousel.
3. TalkBack: Distinguishing between interactions on a finite and infinite carousel.
4. TalkBack (Linear Navigation Only): A potentially infinite number of elements in a carousel could trap focus.
5. Switch Control: Number 4 also effects Switch Control users.
