Systems, Methods, and Graphical User Interfaces for Annotating, Measuring, and Modeling Environments

A computer system, comprising:

• a display device;
• one or more cameras;
• one or more processors;
• and
• memory storing one or more programs, wherein the one or more programs are configured to be executed by the one or more processors, the one or more programs including instructions for:
• displaying, via the display device, an annotation placement user interface, the annotation placement user interface including:
• a representation of a field of view of the one or more cameras, including a representation of a portion of a three-dimensional physical environment that is in the field of view of the one or more cameras, wherein the representation of the field of view is updated over time based on changes in the field of view of the one or more cameras;
• and
• a placement user interface element that indicates a location at which a virtual annotation would be placed in the representation of the field of view in response to receiving an annotation placement input;
• while displaying the annotation placement user interface, detecting movement of the one or more cameras relative to the physical environment;
• and
• in response to detecting the movement of the one or more cameras relative to the physical environment:
• updating the representation of the field of view based on the movement of the one or more cameras;
• in accordance with a determination that the placement user interface element is over at least a portion of a representation of a first type of feature in the physical environment:
• changing an appearance of the placement user interface element to indicate that an annotation would be placed at an anchor point corresponding to the first type of feature in response to an annotation placement input;
• and
• displaying, without receiving an annotation placement input, a first set of one or more guides corresponding to at least a portion of the representation of the first type of feature;
• and
• in accordance with a determination that the placement user interface element is over at least a portion of a representation of a second type of feature in the physical environment, wherein the second type of feature is different from the first type of feature:
• changing the appearance of the placement user interface element to indicate that an annotation would be placed at an anchor point corresponding to the second type of feature in response to an annotation placement input;
• and
• displaying, without receiving an annotation placement input, a second set of one or more guides, different from the first set of one or more guides, corresponding to at least a portion of the representation of the second type of feature.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions that, when executed by a computer system that includes a display device and one or more cameras, cause the computer system to:

• display, via the display device, an annotation placement user interface, the annotation placement user interface including:
• a representation of a field of view of the one or more cameras, including a representation of a portion of a three-dimensional physical environment that is in the field of view of the one or more cameras, wherein the representation of the field of view is updated over time based on changes in the field of view of the one or more cameras;
• and
• a placement user interface element that indicates a location at which a virtual annotation would be placed in the representation of the field of view in response to receiving an annotation placement input;
• while displaying the annotation placement user interface, detect movement of the one or more cameras relative to the physical environment;
• and
• in response to detecting the movement of the one or more cameras relative to the physical environment:
• update the representation of the field of view based on the movement of the one or more cameras;
• in accordance with a determination that the placement user interface element is over at least a portion of a representation of a first type of feature in the physical environment:
• change an appearance of the placement user interface element to indicate that an annotation would be placed at an anchor point corresponding to the first type of feature in response to an annotation placement input;
• and
• display, without receiving an annotation placement input, a first set of one or more guides corresponding to at least a portion of the representation of the first type of feature;
• and
• in accordance with a determination that the placement user interface element is over at least a portion of a representation of a second type of feature in the physical environment, wherein the second type of feature is different from the first type of feature:
• change the appearance of the placement user interface element to indicate that an annotation would be placed at an anchor point corresponding to the second type of feature in response to an annotation placement input;
• and
• display, without receiving an annotation placement input, a second set of one or more guides, different from the first set of one or more guides, corresponding to at least a portion of the representation of the second type of feature.
