The executable data is then communicated to an event engine which executes the executable data to implement the event-based process or modifications to an event-based process corresponding to the received input. One or more aspects of the execution of the event-based process may also be visualized, and graphically modified, though an event monitoring module.

Nearly all computer viruses require an action by a computer user to infect and spread. The key is to educate users not to open e-mail attachments that might carry computer viruses. The key is behavior modification, as education is not sufficient. Effective behavior modification must have a means to reinforce the change and to measure how widespread the change is in a population. The invention is used to reinforce and measure the change in user behavior. The invention sends an e-mail with an attachment to e-mail users and creates a list of all users that open the attachment. The user is sent an e-mail with an attachment that looks similar to attachment that contain computer viruses. If the attachment is opened, an e-mail is sent to a specific e-mail address. This e-mail address collects all of the e-mail from users who have not changed behavior and need additional education or management attention.

This disclosure describes systems and methods for augmented reality (AR) content delivery in pre-captured environments. In one embodiment, an AR client gathers information about the physical environment with the help of sensors embedded within an AR headset. The client reconstructs a 3D model of the physical environment from the gathered information and sends it to an AR content server. Based on the 3D reconstruction information obtained at the AR content server, the server modifies the content. AR content server compares the AR content against the 3D reconstruction data and does a visibility analysis of the AR content. Based on the visibility analysis, the AR elements occluded by real objects are removed to reduce the data size of the AR content. Finally, the AR content server streams the modified content to the AR client and the AR client renders the content and sends it to the headset.
