Systems and methods for enabling low-vision users to interact with a touch-sensitive secondary display

A non-transitory computer-readable storage medium storing executable instructions that, when executed by a computing system with one or more processors, a first housing that includes a primary display, and a second housing at least partially containing a touch-sensitive secondary display that is distinct from the primary display, cause the computing system to:

• display, on the primary display, a first user interface for an application;
• display, on the touch-sensitive secondary display, a second user interface that includes a plurality of application-specific affordances that control functions available within the application, wherein each of the plurality of application-specific affordances is displayed with a first display size;
• detect, via the touch-sensitive secondary display, an input that contacts at least one application-specific affordance of the plurality of application-specific affordances;
• and
• in response to detecting the input and while the input remains in contact with the touch-sensitive secondary display:
• continue to display, on the primary display, the first user interface for the application;
• and
• display, on the primary display, a zoomed-in representation of the at least one application-specific affordance, wherein the zoomed-in representation of the at least one application-specific affordance is displayed with a second display size that is larger than the first display size.

A computing system, comprising:

• one or more processors;
• a first housing that includes a primary display;
• a second housing at least partially containing a touch-sensitive secondary display that is distinct from the primary display;
• and
• memory storing one or more programs that are configured for execution by the one or more processors, the one or more programs including instructions for:
• displaying, on the primary display, a first user interface for an application;
• displaying, on the touch-sensitive secondary display, a second user interface that includes a plurality of application-specific affordances that control functions available within the application, wherein each of the plurality of application-specific affordances is displayed with a first display size;
• detecting, via the touch-sensitive secondary display, an input that contacts at least one application-specific affordance of the plurality of application-specific affordances;
• and
• in response to detecting the input and while the input remains in contact with the touch-sensitive secondary display:
• continuing to display, on the primary display, the first user interface for the application;
• and
• displaying, on the primary display, a zoomed-in representation of the at least one application-specific affordance, wherein the zoomed-in representation of the at least one application-specific affordance is displayed with a second display size that is larger than the first display size.
