The augmented reality display device can provide the user with virtual information of related objects in a real environment, such as a computer rendered text description or image. However, due to the limitation of the viewing angle of the device, the user cannot obtain the information related to the object outside the visual field (such as the back of the user), resulting in the user may miss the opportunity to interact with it.
A few days ago, a Microsoft patent (patent number) passed by the U.S. Patent Office provided a solution to this problem. The patent discloses that an augmented reality device can provide users with information indications of related objects outside the field of view in a real environment, and these indications can be of any type, including but not limited to audio indications or visual indications.
The following is an example diagram of an augmented reality device (104) that includes one or more lenses, a speaker, one or more microphones (acquiring a user's voice instructions), one or more externally-facing image sensors (obtaining the user viewing Or the physical space image on the back of the user may include one or more depth sensors/two-dimensional image sensors), one or more motion sensors. According to Xiaobian, augmented reality devices (104) also have functions such as eye tracking, GPS positioning, and head tracking.
The lower diagrams (1A and 1B) are examples of the user (106) using the augmented reality display device (104) in the use environment (100), while the use environment (100) includes a plurality of cross streets and various restaurants, banks and the like ( Including buildings 120, 122, 124, 126, and 128) also includes virtual objects or visual identities displayed in association with these real objects. FIG. 1A shows a perspective of the use environment (100) of the user (106) field of view, and FIG. 1B shows a top view of the use environment (100 ). The view angle area (102) is an environment that the user can partially view through the augmented reality display device (104).
For a specific application scenario, when the user (106) requests to display information of all nearby restaurants in the use environment (100), the augmented reality display device (104) may mark the virtual identification of the restaurant in the corresponding building, as shown in FIG. The plurality of angle markers (153) in 1A are loaded on the building (120), and other information of the building (120) such as restaurant name, telephone number, menu can be further displayed or obtained by clicking the identifier (153). , diners, etc. Although the buildings (122, 124, 126, and 128) also contain restaurants, because these restaurants are not within the field of view (102), the user (106) cannot fully acquire all restaurant information within the use environment (100). Therefore, the augmented reality device (104) can display various instructions to the user, such as audio or visual information for the user outside the field of view, and this indication provides a persistent or non-persistent response according to user needs. .
