Other potential compliance areas include airspace regulations, surveillance (electronic, physical, xR), permissions and tracking, and access tracking (i.e., who gets access to what locations, and what permissions may exist in those locations). Other examples include consumer privacy regulation (electronic, xR separate from electronic, internet privacy, tracking, physical, etc.), antitrust regulation, control over private companies, food and drug regulation, occupational safety, environmental regulation, monetary policy, fiscal policy, utility regulation and service, media regulation (i.e., regulating the electromagnetic spectrum), net neutrality regulation, free speech, telephonics, and trade regulation. Additionally, a government entity may use an xR registry to notify users of government facilities (i.e., buildings and parks) of hours of operation and rules for public spaces.
The use of an xR registry also has a number of implications for enforcement and protection of privacy related rules and regulations. The concept of xR (especially AR) may depend on the ability of the device to record and analyze the environment in real time. While constitutional law may allow for such recording in the name of public interest, the constant recording of a rendering device may make it difficult to do so without also recording outside of the public domain. People may have an expectation of privacy in certain areas or domains. An xR registry may be utilized to enable rendering devices to operate without violating people's expectation of privacy.
