  • the Navigation Logic 140 can respond to a contact gesture by initiating the image analysis in an area around the pixels that were touched and if something is positively identified in the analyzed portion of the image, then the Navigation Logic 140 can display information stored for that object or person, or can search for information, and provide a brief summary as information in the overlay proximate to whatever was identified.
  • Navigation Logic 140 is optionally further configured to save the image presently displayed on the Display 125 in response to a contact gesture, the image being a screen shot but without the overlay provided by the present invention.
  • Navigation Logic 140 is optionally further configured to reorient the displayed portion of the navigable environment in response to a contact gesture, for example, a contact gesture can reorient the displayed portion of the navigable environment to show the opposite (back) view.
  • Navigation Logic 140 is further configured to control both the angle and the position of a viewpoint, that is, change the location within the environment from which the environment is presented to the Display 125 as well as change the direction of the view from that location.
  • “Position of a viewpoint” is the particular location, or point, in the environment from which the view originates.
  • Angle of a viewpoint is the direction, in a coordinate system of the environment, in which the environment is observed from the position of the viewpoint. Changing the angle and position of the viewpoint has the effect of panning and zooming, analogous to a person at the position of the viewpoint turning their head or moving within the navigable environment.
  • Navigation Logic 140 is further configured to receive from UI Logic 135 contact gestures and to recognize some as commands to change the position of the viewpoint, and to recognize other contact gestures as commands to change the viewpoint. Both types of contact gestures, in some embodiments, share in common that the gesture originates on a first part of the Display 125 and extends to another part of the Display 125 before ending. In some instances, a filter may recognize a contact gesture as initiated and pass the information to the Navigation Logic 140 before the contact gesture is completed. Accordingly, the Navigation Logic 140 can respond to a contact gesture and change the display of the environment while the contact gesture is still in progress. [0035] The first and/or second parts of the display are optionally indicated by Symbols 210, 215.
  • a touch that originates at Symbol 210 is used to control the angle of the viewpoint while a touch that originates at Symbol 215 is used to control the position of the viewpoint itself. For instance, touching at Symbol 210 and swiping up results in an upward change in the angle of the viewpoint, touching at Symbol 210 and swiping right results in a rightward change in the angle of the viewpoint, etc. Touching at Symbol 215 and swiping upward results in movement of the position of the viewpoint forward in the navigable environment, touching at Symbol 215 and swiping right results in movement of the position of the viewpoint to the right, etc.
  • Computing Device 110A is a hand-held device and held with two hands so that each thumb is used to touch the Symbols 210 and 215 respectively.
  • touching at Symbol 210 serves to select the Symbol 210 such that the Symbol 210 is dragged along with any swipe that originates therein.
  • the Symbol 210 is returned to its home location on the Display 125.
  • Display 125 is shown in FIG. 2B in the portrait mode. In some embodiments, only one of Symbols 210, 215 is provided by Navigation Logic 140 when in the portrait mode. The operations of UI Logic 135 and Navigation Logic 140 are, thus, optionally dependent on the orientation of Computing Device 110A. The functionality of different parts of Display 125 may change depending on the orientation of Display 125. In the example shown, Symbol 215 represents the part of Display 125 from which the position of the viewpoint is manipulated. A contact gesture that originates in this part of Display 125 and swipes outward therefrom is interpreted by UI Logic 135 as a command to change the position of the viewpoint within the environment.
  • a touch that originates in any other part of Display 125 and swiped is interpreted by UI Logic 135 as a command to change the angle of the viewpoint.
  • UI Logic 135 a command to change the angle of the viewpoint.
  • FIG. 2C illustrates examples of swiping motions that may occur on Display 125 in the landscape mode.
  • Swipes 220 that originate from outside of the Symbol 215 are used to change the angle of the viewpoint, and in some embodiments this includes the entire touch- sensitive surface of the Display 125 that is outside of the Symbol 215, or can be in just a portion of the Display 125 outside of the Symbol 215.
  • the length or strength of a Swipe 220 can optionally be used as a means of control, for instance, the amount of change of the angle of the viewpoint can be proportional to the length of the swipe 220.
  • Swipes 225 that originate at the part of the Display 125 indicated by Symbol 215 are used to change the position of the viewpoint.
  • swiping can be along a straight or a curved path.
  • the path of a swipe optionally is interpreted by UI Logic 135 as a contact gesture having a specific meaning.
  • the degree of curvature of a swiping gesture is optionally used to control a curvature of a path along which viewpoint position is changed for the displayed environment. For example, a gesture that originates at Symbol 215 and curves to the area indicated by Boxes 230 in FIG. 2C results in a position of the viewpoint change forward with a gradual turn (right or left).
  • Boxes 230 and 235 are not necessarily visible on Display 125 but merely represent, for the sake of illustration, regions of the Display 125. As such, boxes 230 and 235 may represent either discrete regions or a continuum in which a large number of alternative gestures may terminate.
  • a contact gesture originating from the area of Display 125 indicted by Symbol 215 can be held on the Display 125 at the end of the gesture.
  • the resulting change (rate and direction) in the position of the viewpoint will continue until the digit is lifted from Display 125.
  • the amount of viewpoint position change is dependent on the length of time the digit is in contact with Display 125.
  • the part of the Display 125 used to control the angle of the viewpoint includes a greater amount of the Display 125 in portrait mode relative to landscape mode. Specifically, a ratio of an area of the part of the display for viewpoint change to an area of the first part of the display for position change is greater in portrait mode relative to landscape mode.

Abstract

L'invention concerne des dispositifs activés par écran tactile permettant d'afficher des images soit d'environnements réels, soit d'environnements virtuels, les dispositifs ayant des interfaces utilisateur comprenant une superposition graphique posée sur les images pour naviguer dans les environnements. Le dispositif peut interpréter des gestes effectués par l'utilisateur sur l'écran tactile en tant que commandes, et la superposition graphique guide l'utilisateur quant à l'endroit où effectuer les gestes pour réaliser des manœuvres prévues telles que des translations du point de vue et des rotations du point de vue dans l'environnement affiché. La superposition graphique peut ne comprendre qu'un seul symbole, et des gestes qui proviennent dans la zone de l'affichage marquée par le symbole sont différenciés de ceux provenant de l'extérieur du symbole, les gestes différenciés commandant la translation et la rotation, respectivement. Ceci permet une navigation de l'environnement avec un seul doigt.
