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, memory, 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:
• (i) a plurality of application-specific affordances that control functions available within the application and (ii) at least one system-level affordance that controls a system-level function;
• detect, via the touch-sensitive secondary display, a first input over a first application-specific affordance of the plurality of application-specific affordances;
• and
• while the first input remains in contact with the first application-specific affordance:
• detect, via the touch-sensitive secondary display, a second input that is not over the first application-specific affordance;
• and
• in response to detecting the second input, activate the first application-specific affordance.

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:
• (i) a plurality of application-specific affordances that control functions available within the application and (ii) at least one system-level affordance that controls a system-level function;
• detecting, via the touch-sensitive secondary display, a first input over a first application-specific affordance of the plurality of application-specific affordances;
• and
• while the first input remains in contact with the first application-specific affordance:
• detecting, via the touch-sensitive secondary display, a second input that is not over the first application-specific affordance;
• and
• in response to detecting the second input, activating the first application-specific affordance.
