Attention-based notifications

One or more non-transitory computer-readable storage media including instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:

• causing a first visual stimulus to be oscillated with a first frequency pattern, wherein the first visual stimulus comprises a first notification, and wherein the first frequency pattern comprises oscillation at a first frequency for a first period of time and oscillation at a second frequency for a second period of time subsequent to the first period of time;
• determining a second frequency pattern associated with a user characteristic;
• and
• in response to a determination that the second frequency pattern does not match the first frequency pattern, causing a second notification to be output, wherein the second notification comprises an audio notification or a haptic notification.

A system, comprising:

• a memory storing an application;
• and
• a processor that, when executing the application, is configured to:
• cause a first visual stimulus to be oscillated with a first frequency pattern, wherein the first visual stimulus comprises a first notification, and wherein the first frequency pattern comprises oscillation at a first frequency for a first period of time and oscillation at a second frequency for a second period of time subsequent to the first period of time;
• determine a second frequency pattern associated with a pupil of an eye;
• in response to a determination that the second frequency pattern does not match the first frequency pattern, determine a lack of attention on the first visual stimulus;
• and
• in response to determining the lack of attention on the first visual stimulus, cause a second notification to be output, wherein the second notification, wherein the second notification comprises an audio notification or a haptic notification.
