Advertising impression determination

1. A method for rendering content within an environment, the method comprising:

defining one or more content areas each at a respective location within an environment associated with a user;

storing information in memory that associates each of the defined content areas with a respective digital content file; and

executing instructions stored in memory, wherein execution of the instructions by a processor:

identifies a location of a user perspective within the environment;

monitors controls by the user of the identified user perspective to identify at least one line-of-sight path;

identifies at least one of the content areas along the line-of-sight path, wherein the line-of-sight path is at least partially unobstructed;

renders the digital content file associated with the identified content area;

tracks user interaction with the rendered digital content file; and

updates a display of the rendered digital content file based on the tracked user interaction.

2. The method of claim 1 , wherein the digital content file is rendered at a location of the defined content area.

3. The method of claim 1 , further comprising updating the stored information to replace the digital content file associated with the identified content area with a different digital content file.

4. The method of claim 3 , wherein replacing the associated digital content file is based on the monitored controls.

5. The method of claim 3 , wherein replacing the associated digital content file is based on the tracked user interaction.

6. The method of claim 1 , further comprising receiving input selecting one of a plurality of different available content channels via an interface, wherein the rendered digital content file is associated with the identified content area based on the content channel selected by the input.

7. The method of claim 1 , wherein the digital content file is rendered relative to a surface within the environment.

8. The method of claim 1 , wherein tracking the user interactions is further based on speech input detected via a microphone associated with the user.

9. The method of claim 1 , wherein the tracked user interactions includes an index of a state of the digital content file, and wherein updating the display of the rendered digital content file is based on the state of the digital content file indicated by the index.

10. A system for rendering content within an environment, the system comprising:

memory that stores:

definitions of one or more content areas each at a respective location within an environment associated with a user;

information associating each of the defined content areas with a respective digital content file;

a processor that executes instructions stored in the memory, wherein execution of the instructions by the processor:

identifies a location of a user perspective within the environment,

monitors controls by the user of the identified user perspective to identify at least one line-of-sight path,

identifies at least one of the content areas along the line-of-sight path, wherein the line-of-sight path is at least partially unobstructed,

renders the digital content file associated with the identified content area, and

tracks user interaction with the rendered digital content file; and

a screen that displays the rendered digital content file, wherein the display of the rendered digital content file is subsequently updated by the processor based on the tracked user interaction.

11. The system of claim 10 , wherein the digital content is rendered at a location of the defined content area.

12. The system of claim 10 , wherein the processor updates the stored information to replace the digital content file associated with the identified content area with a different digital content file.

13. The system of claim 12 , wherein the processor replaces the associated digital content file based on the monitored controls.

14. The system of claim 12 , wherein the processor replaces the associated digital content file based on the tracked user interaction.

15. The system of claim 10 , further comprising a user interface that receives input selecting one of a plurality of different available content channels via an interface, wherein the rendered digital content is associated with the identified content area based on the content channel selected by the input.

16. The system of claim 10 , wherein the digital content file is rendered relative to a surface within the environment.

17. The system of claim 10 , further comprising a microphone associated with the user, wherein the processor tracks the user interactions is further based on speech input detected via the microphone.

18. The system of claim 10 , wherein the tracked user interactions includes an index of a state of the digital content file, and wherein the processor updates the display of the rendered digital content file based on the state of the digital content file indicated by the index.

19. A non-transitory computer-readable storage medium, having embodied thereon a program executable by a processor to perform a method for rendering content within an environment, the method comprising:

defining one or more content areas each at a respective location within an environment associated with a user;

storing information in memory that associates each of the defined content areas with a respective digital content file;

identifying a location of a user perspective within the environment;

monitoring controls by the user of the identified user perspective to identify at least one line-of-sight path;

identifying at least one of the content areas along the line-of-sight path, wherein the line-of-sight path is at least partially unobstructed;

rendering the digital content file associated with the identified content area;

tracking user interaction with the rendered digital content file; and

updating a display of the rendered digital content file based on the tracked user interaction.
