Utilizing topological maps for augmented or virtual reality

Abstract

An augmented reality display system comprises a passable world model data comprises a set of map points corresponding to one or more objects of the real world. The augmented reality system also comprises a processor to communicate with one or more individual augmented reality display systems to pass a portion of the passable world model data to the one or more individual augmented reality display systems, wherein the piece of the passable world model data is passed based at least in part on respective locations corresponding to the one or more individual augmented reality display systems.

1 . A method of displaying augmented reality, comprising:
 detecting a characteristic of a physical environment of a user of a head-mounted augmented reality display system;   receiving a command to display a virtual object;   modifying the virtual object based on the detected characteristic of the physical environment to generate a modified virtual object; and   displaying the modified virtual object in an augmented reality scene including the physical environment to the user.   
     
     
         2 . The method of  claim 1 , wherein the characteristic of the physical environment is a light color of a surface. 
     
     
         3 . The method of  claim 2 , wherein modifying the virtual content comprises changing a color of the virtual content to a dark color. 
     
     
         4 . The method of  claim 1 , further comprising detecting a light of the physical environment,
 wherein the characteristic of the physical environment is the detected light of the physical environment.   
     
     
         5 . The method of  claim 4 , wherein modifying the virtual content comprises dynamically altering a color of the virtual content. 
     
     
         6 . The method of  claim 5 , wherein dynamically altering the color of the virtual content comprises darkening or lightening the color. 
     
     
         7 . The method of  claim 1 , wherein the characteristic of the physical environment is a white color of a surface. 
     
     
         8 . The method of  claim 7 , wherein modifying the virtual content comprises rendering a color halo around the virtual content. 
     
     
         9 . The method of  claim 1 , wherein the characteristic of the physical environment is a light color of a surface. 
     
     
         10 . The method of  claim 9 , wherein modifying the virtual content comprises changing a color of the virtual content to a light color. 
     
     
         11 . A head-mounted augmented reality display system, comprising:
 a sensor to detect a characteristic of a physical environment of a user of the head-mounted augmented reality display system;   a processor to:
 receiving a command to display a virtual object, and 
 modifying the virtual object based on the detected characteristic of the physical environment to generate a modified virtual object, and 
   a display system to display the modified virtual object in an augmented reality scene including the physical environment to the user   
     
     
         12 . The system of  claim 11 , wherein the characteristic of the physical environment is a light color of a surface. 
     
     
         13 . The system of  claim 12 , wherein modifying the virtual content comprises changing a color of the virtual content to a dark color. 
     
     
         14 . The system of  claim 11 , wherein the sensor is also configured to detect a light of the physical environment, and
 wherein the characteristic of the physical environment is the detected light of the physical environment.   
     
     
         15 . The system of  claim 14 , wherein modifying the virtual content comprises dynamically altering a color of the virtual content. 
     
     
         16 . The system of  claim 15 , wherein dynamically altering the color of the virtual content comprises darkening or lightening the color. 
     
     
         17 . The system of  claim 11 , wherein the characteristic of the physical environment is a white color of a surface. 
     
     
         18 . The system of  claim 17 , wherein modifying the virtual content comprises rendering a color halo around the virtual content. 
     
     
         19 . The system of  claim 11 , wherein the characteristic of the physical environment is a light color of a surface. 
     
     
         20 . The system of  claim 19 , wherein modifying the virtual content comprises changing a color of the virtual content to a light color.
