Title
(EN) METHOD AND DEVICE FOR USING AUGMENTED REALITY IN TRANSPORTATION
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT D'UTILISER LA RÉALITÉ AUGMENTÉE DANS LE TRANSPORT
Abstract
(EN)
Augmented reality may be used to help navigate a user to a desired location. A first location and a device orientation of a user device may be obtained. A second location may be obtained. A path from the first location to the second location may be determined. A camera feed may be displayed on the user device. An indicator of the path may be displayed over the camera feed based on the device orientation. A marker may be displayed over the camera feed in response to determining that the device orientation aligns with the second location, and the marker may indicate the second location.
(FR)
Selon la présente invention, la réalité augmentée peut être utilisée pour aider un utilisateur à naviguer vers un emplacement souhaité. Un premier emplacement et une orientation de dispositif d'un dispositif utilisateur peuvent être obtenus. Un second emplacement peut être obtenu. Un trajet allant du premier emplacement au second emplacement peut être déterminé. Une alimentation de caméra peut être affichée sur le dispositif d'utilisateur. Un indicateur du trajet peut être affiché sur l'alimentation de caméra sur la base de l'orientation du dispositif. Un marqueur peut être affiché sur l'alimentation de caméra en réponse à la détermination que l'orientation du dispositif s'aligne sur le second emplacement, et le marqueur peut indiquer le second emplacement.
