LENS VIEW FOR MAP

BACKGROUND

Many applications and/or websites provide information through maps. For example, a videogame may display a destination for a user on a map; a running website may display running routes through a web map interface; a mobile map app may display driving directions on a road map; a realtor app may display housing information, such as images, sale prices, home value estimates, and/or other information on a map; etc. Such applications and/or websites may facilitate various types of user interactions with maps. In an example, a user may zoom-in, zoom-out, and/or rotate a viewing angle of a map. In another example, the user may mark locations within a map using pinpoint markers (e.g., create a running route using pinpoint markers along the route). In this way, users may view various information and/or perform various tasks through maps.

SUMMARY

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

Among other things, one or more systems and/or techniques for providing a lens view associated with a map canvas are provided. A user interface (e.g., an app such as a realtor app, a website such as a driving directions website, a GPS map device, etc.) may display a map canvas at a first scale. For example, the map canvas may display a shopping district of a city. The map canvas may be populated with a lens view depicting a location, associated with the map canvas, at a second scale having a higher level of granularity than the first scale. For example, the lens view may depict imagery of a department store building within the shopping district (e.g., photos depicting the department store at a street-level view, such as a view that is normal to a horizon of the shopping district). Rotation of the map canvas may change the map canvas from a current map heading to a rotated map heading (e.g., programmatic input, such as by an application, panorama functionality, or other functionality, may rotate the map canvas; user input, such as a touch gesture, a mouse or keyboard input, and/or movement of a device captured by a gyroscope, compass, and/or other sensor may rotate the map canvas; etc.). Accordingly, a current leans heading of the lens view may be modified to a rotated lens heading corresponding to the rotated map heading. For example, responsive to a user rotating the map canvas in a clockwise direction, the lens view may be rotated in a clockwise direction (e.g., to maintain a one-to-one correspondence between a map heading and a lens heading). In an example, responsive to rotation of the lens view, the lens view and/or the map canvas may be rotated based upon the lens view rotation. In an example, a lens pitch of the lens view may be maintained (e.g., unmodified) when a map pitch of the map canvas is changed.

To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages, and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.

DETAILED DESCRIPTION

The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are illustrated in block diagram form in order to facilitate describing the claimed subject matter.

An embodiment of providing a lens view associated with a map canvas is illustrated by an exemplary method 100 of FIG. 1. At 102, the method starts. At 104, a map canvas may be displayed at a first scale. For example, the map canvas may depict a few square miles of a college campus. In an example, imagery, such as photos, may be available for one or more locations within the map canvas (e.g., a student may have shared photos of a student union building through a social network or microblog message).

At 106, the map canvas may be populated with a lens view depicting a location, associated with the map canvas, at a second scale having a higher level of granularity than the first scale. In an example, the lens view may be populated within the map canvas based upon a touch gesture associated with the map canvas (e.g., a user may ‘touch’ the location on the map, the user may select an interface element representing the location, etc.). In an example, the lens view may depict imagery of the location (e.g., a panorama view of the student union building stitched together using the photos shared by the user). In an example, the lens view may depict the location according to a street-level view, such as a view that is normal to a horizon of the location or a view having a lens pitch between about −15° and about +15°. In an example, the lens view may be displayed within the map canvas (e.g., as a user interface element within the map canvas). In another example, the map canvas may be displayed within a map interface, and the lens view may be displayed within an interface not comprised within the map interface (e.g., a side-bar interface; an interface that is adjacent to the map interface; a pop-up/floating interface; etc.).

The lens view may be anchored to the location within the map canvas utilizing a stem. For example, the stem may anchor the lens view based upon a longitude value and/or a latitude value. Responsive to a change in position of the map canvas (e.g., rotational movement, panning movement, pitch movement, etc.), the stem may be utilized to anchor the lens view to the location within the map canvas. Response to determining that the map canvas is displayed according to a nadir view (e.g., a top-down view along a plumb line), the stem may be displayed at a position relative to the lens view and the location within the map canvas (e.g., the stem may be displayed along an edge of the lens view at a position corresponding the location). In an example, responsive to determining that a lens position of the lens view corresponds to a map entity position of an entity within the map canvas (e.g., a 3D structure, such as a building), the lens view may be displayed over the entity (e.g., a z-position of the lens view (e.g., perpendicular to the plane within which the map canvas lies) may be specified such that the lens view overlays the map canvas and/or entities populated therein).

At 108, responsive to rotation of the map canvas changing a current map heading of the map canvas to a rotated map heading (e.g., a heading corresponding to points of a compass), modifying a current lens heading of the lens view to a rotated lens heading corresponding to the rotated map heading. For example, responsive to a user rotating the map canvas in a clockwise direction (e.g., from a North heading to a Northeast heading), the lens view may be rotated in a clockwise direction (e.g., such as from a North heading to a Northeast heading in order to maintain a one-to-one correspondence between a map heading and a lens heading). In an example, responsive to identifying rotational input associated with the lens view, the lens view and the map canvas may be rotated based upon the rotational input. Rotational input for the map canvas and/or the lens view may be detected based upon touch input, application programmatic input (e.g., an animation, panorama functionality, an application, a web service, an app, a code module, an operating system, a videogame, etc.), gyroscopic input, compass input, and/or user input. In contrast to maintaining a correspondence between the map heading and the lens heading, a lens pitch of the lens view may be maintained notwithstanding a change in map pitch for the map canvas. For example, responsive to identifying a change in map pitch for the map canvas, the lens pitch of the lens view may be refrained from being modified. In an example, responsive to receiving input associated with the lens view, the map canvas may be transitioned to an interactive street-level depiction of the location (e.g., an interactive panorama view of the student union building). At 110, the method ends.

FIG. 2 illustrates an example 200 of a map canvas 202. The map canvas 202 may be provided by a website (e.g., a mapping website), a web service, a cloud service, a mobile app (e.g., a realtor app, a running app, a map app, etc.), an application, a GPS device, a videogame console (e.g., a map provided by a video game), and/or through any other computing device. Locations within the map canvas 202 may be associated with imagery depicting such locations. For example, the map canvas 202 may depict a shopping district of a city having a first location 204, a second location 206, a third location 208, a fourth location 210, and a fifth location 212 associated with imagery depicting such locations. Responsive to selection of a location, a lens view depicting the location (e.g., displaying the imagery, a panorama derived from the imagery, and/or other view of the location) may be populated within the map canvas 202 (e.g., FIG. 3A).

FIG. 3A illustrates an example of a system 300 for providing a lens view 302 associated with a map canvas 202. The system 300 may comprise a lens management component 306 associated with the map canvas 202. The map canvas 202 may depict a shopping district of a city having a first location 204, a second location 206, a third location 208, a fourth location 210, and a fifth location 212 associated with imagery depicting such locations. Responsive to selection of the first location 204, the lens management component 306 may be configured to populate the map canvas 202 with the lens view 302. The lens view 302 may be anchored to the first location 204 by a stem 304. The stem 304 may be used to anchor the lens view 302 to the first location 204 notwithstanding a change in position of the map canvas 202 (e.g., a panning movement, rotational movement, a change in pitch, zooming in or out, etc.). The lens view 302 may depict a videogame store (e.g., based upon imagery of the videogame store) at the first location 204 within the shopping district. The lens view 302 may depict the videogame store according to a street-level view that is normal to a horizon of the first location 204 (e.g., the street-level view may have a lens pitch between about −15° and about +15°). The map canvas 202 may depict the shopping district according to a first scale, and the lens view 302 may depict the videogame store according to a second scale having a higher level of granularity than the first scale. In this way, a user may view details of the videogame store at a higher level of detail through the lens view 302 without having to change a scale of the map canvas 202.

FIG. 3B illustrates an example of a system 350 for modifying a lens heading of a lens view 302 based upon a map heading of a map canvas 202. The system 350 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with the lens view 302 depicting a first location 204, such as a videogame store, within the map canvas 202 (e.g., FIG. 3A). The lens management component 306 may be configured to detect a rotation 352 of the map canvas 202 that changes a current map heading of the map canvas 202 to a rotated map heading (e.g., based upon user touch input, user mouse input, etc.). Accordingly, the lens management component 306 may be configured to modify 354 a current lens heading of the lens view 302 to a rotated lens heading corresponding to the rotated map heading. In this way, a correspondence between the lens heading and the canvas heading may be maintained.

FIG. 3C illustrates an example of a system 370 for modifying a map heading of a map canvas 202 based upon a lens heading of a lens view 302. The system 370 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with the lens view 302 depicting a first location 204, such as a videogame store, within the map canvas 202 (e.g., FIG. 3A). The lens management component 306 may be configured to detect a rotation 372 of the lens view 302 (e.g., based upon user touch input, user mouse input, etc.). The lens management component 306 may rotate the lens view 302 (e.g., modifying the lens heading of the lens view 302) and/or may rotate 374 the map canvas (e.g., modifying the map heading of the map canvas 202) based upon the rotational input 372. In this way, a correspondence between the lens heading and the canvas heading may be maintained.

FIG. 3D illustrates an example of a system 390 for maintaining a lens pitch of a lens view 302 notwithstanding a change in map pitch for a map canvas 202. The system 390 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with the lens view 302 depicting a first location 204, such as a videogame store, within the map canvas 202 (e.g., FIG. 3A). The lens management component 306 may be configured to detect a change 392 in map pitch for the map canvas 202. Responsive to the change 392 in map pitch, the lens management component 306 may refrain from modifying the lens pitch of the lens view 302. In this way, the lens pitch of the lens view 302 is maintained notwithstanding the change in map pitch for the map canvas 202. In an example, imagery of the video game store displayed through the lens view 302 remains substantially static (e.g., such that a user may continue to view, browse, etc. video games through the lens view 302) despite a change in pitch of the map canvas 202.

FIG. 4 illustrates an example of a system 400 for displaying a lens view 302. The system 400 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with the lens view 302 depicting a first location 204, such as a videogame store, within the map canvas 202 (e.g., FIG. 3A). In an example, the map canvas 202 may be populated with one or more entities, such as a first 3D building entity 402 and a second 3D building entity 404. The lens management component 306 may be configured to display the lens view 302 over the first 3D building entity 402, the second 3D building entity 404, and/or other entities. For example, the lens management component 306 may set a z-position for the lens view 302 to a value greater than or equal to a z-position of the first 3D building entity 402, the second 3D building entity 404, and/or other entities so that the lens view 302 is not obscured by the 3D or other entities on the map canvas 202.

FIG. 5A illustrates an example of a system 500 for displaying a lens view 302. The system 500 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with the lens view 302 depicting a location 508, such as an office building in a downtown portion of a city, within the map canvas 202. In an example, the map canvas 202 may be displayed according to a nadir view (e.g., a top-down view along a plumb line that is substantially perpendicular to a plane within which the map canvas 502 lies). The lens management component 306 may anchor the lens view 302 to the location 508 using a stem 304. The stem 304 may be used for anchoring the lens view and/or may be displayed notwithstanding the map canvas 202 being displayed according to the nadir view. For example, the stem 304 may be displayed along an edge of the lens view 302 at a position between the lens view 302 and the location 508.

FIG. 5B illustrates an example of a system 550 for displaying an interactive street-level depiction 552 of a location 508 within a map canvas 202. The system 500 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with a lens view 302 depicting the location 508, such as an office building, within the map canvas 202 (e.g., FIG. 5A). The lens management component 306 may receive input associated with the lens view 302 (e.g., user input such as a selection of the lens view 302; application programmatic input used to invoke a selection method/function for the lens view 302; etc.). Accordingly, the lens management component 306 may transition the map canvas 202 to the interactive street-level depiction 552 of the location 504 based upon the input (e.g., the interactive street-level depiction 552 may be displayed within an interactive user interface within the map canvas 202). For example, a user may navigate around the location 508 by interacting with the interactive street-level depiction 552 (e.g., tilt, rotate, pan, zoom, entity selection, product purchase, endorse, like, comment, review, and/or other interaction may be facilitated through the interactive street-level depiction 552).

FIG. 5C illustrates an example of a system 570 for displaying an interactive street-level depiction 572 of a location 508 within a map canvas 202. The system 500 may comprise a lens management component 306 associated with the map canvas 202. In an example, the lens management component 306 may have populated the map canvas 202 with a lens view 302 depicting the location 508, such as an office building, within the map canvas 202 (e.g., FIG. 5A). The lens management component 306 may receive input associated with the lens view 302 (e.g., user input such as a selection of the lens view 302; application programmatic input used to invoke a selection method/function for the lens view 302; etc.). Accordingly, the lens management component 306 may transition the map canvas 202 to the interactive street-level depiction 572 of the location 508 (e.g., the interactive street-level depiction 572 may be displayed within an interactive user interface that may replace the map canvas 202). For example, a user may navigate around the location 508 by interacting with the interactive street-level depiction 572 (e.g., tilt, rotate, pan, zoom, entity selection, product purchase, endorse, like, comment, review and/or other interaction may be facilitated through the interactive street-level depiction 572).

FIG. 6 illustrates an example of a system 600 for displaying a lens view 302. The system 600 may comprise a lens management component 306 associated with a user interface 602. The user interface 602 may depict a map canvas 202 comprising a location 508. The map canvas 202 may be displayed through a map interface 610. Responsive to a selection of the location 508, the lens management component 306 may display the lens view 302 within an interface 612. In an example, the interface 612 is not comprised within the map interface 610. In an example, the interface 612 is displayed adjacent to the map interface 610, such as within a side bar interface.
