With the growing involuntary saturation of advertising in society, it becomes evident that filters will be designed to restore peace where desired. AdBlock first brought us virtual content aware filters of advertising material in 2006.
I propose Reverse Augmented Reality - non-virtual content aware
filters (technology that shuts out information from the outside world). Such technology needn't be restricted to advertising material, but could be used to target any content the user desires. For example, it could be used as a mature content filter for children.
[UPDATE] Augmented Reality applications could also be designed to overlay offensive material, for example with that which is (less provocative and) more beautiful. "More pirates".
