Systems and methods for accessing a nested menu

A method for providing a virtual menu to a user of a wearable device, the method comprising:

• monitoring, based on an angle output by at least one sensor, an orientation of the wearable device relative to a horizontal plane, the angle being indicative of the orientation of the wearable device relative to the horizontal plane, wherein the at least one sensor is attached to a frame which is configured to secure the wearable device to a head of the user;
• causing the menu to appear on a display of the wearable device based on the angle output by the at least one sensor being greater than or equal to a predetermined threshold angle, wherein a location of the menu in a horizontal direction on the display is unaffected by horizontal movement of the wearable device;
• causing an indicator of a predetermined dwell time threshold representing a time duration to be shown on the display;
• determining, based on the monitored orientation, whether the user is looking in a direction of the location of the menu on the display;
• in response to a determination that the user is looking in the direction of the location of the menu, monitoring a time period that the user is looking in the direction of the location of the menu;
• determining whether the orientation of the wearable device has changed from a first orientation to a second orientation;
• in response to a determination that the orientation of the wearable device has changed from a first orientation to a second orientation, determining whether a difference between the first orientation and the second orientation is less than an orientation threshold;
• in response to a determination that the difference between the first orientation and the second orientation is less than the orientation threshold, continuing to monitor the time period that the user is looking in the direction of the location of the menu;
• in response to a determination that the difference between the first orientation and the second orientation is not less than the orientation threshold, resetting the time period that the user is looking in the direction of the location of the menu to zero;
• and
• expanding the menu if the user is determined to be looking in the direction of the location of the menu on the display and the monitored time period that the user is looking in the direction of the location of the menu exceeds the predetermined dwell time threshold.

A non-transitory computer-readable storage medium storing program instructions executable by at least one processor to perform a method for providing a virtual menu to a user of a wearable device, the method comprising:

• monitoring, based on an angle output by at least one sensor, an orientation of the wearable device relative to a horizontal plane, the angle being indicative of the orientation of the wearable device relative to the horizontal plane, wherein the at least one sensor is attached to a frame which is configured to secure the wearable device to a head of the user;
• causing the menu to appear on a display of the wearable device based on the angle output by the at least one sensor being greater than or equal to a predetermined threshold angle, wherein a location of the menu in a horizontal direction on the display is unaffected by horizontal movement of the wearable device;
• causing an indicator of a predetermined dwell time threshold representing a time duration to be shown on the display;
• determining, based on the monitored orientation, whether the user is looking in a direction of the location of the menu on the display;
• in response to a determination that the user is looking in the direction of the location of the menu, monitoring a time period that the user is looking in the direction of the location of the menu;
• determining whether the orientation of the wearable device has changed from a first orientation to a second orientation;
• in response to a determination that the orientation of the wearable device has changed from a first orientation to a second orientation, determining whether a difference between the first orientation and the second orientation is less than an orientation threshold;
• in response to a determination that the difference between the first orientation and the second orientation is less than the orientation threshold, continuing to monitor the time period that the user is looking in the direction of the location of the menu;
• in response to a determination that the difference between the first orientation and the second orientation is not less than the orientation threshold, resetting the time period that the user is looking in the direction of the location of the menu to zero;
• and
• expanding the menu if the user is determined to be looking in the direction of the location of the menu on the display and the monitored time period that the user is looking in the direction of the location of the menu exceeds the predetermined dwell time threshold.
