The method comprises selecting immersive content for displaying to a patient who is experiencing delirium, comprising selecting said immersive content from a database based on a time of day attribute associated with the immersive content; and administering the selected immersive content to the patient, by displaying said content to the patient on a display, and simultaneously playing any audio component of said content to the patient. ## Claims ### Claim 1 A computer-implemented method, comprising: selecting immersive content, from a database, for displaying to a patient who is experiencing delirium based on a time of day attribute associated with the immersive content; administering the selected immersive content to the patient based on a dose, by displaying said immersive content to the patient on a virtual reality device, and simultaneously playing an audio component of said immersive content to the patient; administering a delirium test to the patient via the virtual reality device periodically, and analyzing results of the delirium test to quantify a level of delirium experienced by the patient in terms of a delirium score; and determining the dose for the patient based on said delirium level, wherein the dose is based on a predefined time for which the immersive content is to be shown to the patient. ### Claim 2 (depends on 1) The method of claim 1, further comprising indexing said immersive content based on a time of day associated with the immersive content. ### Claim 3 (depends on 1) The method of claim 1, further comprising indexing said immersive content with additional attributes selected from the group consisting of neighborhood location, city, tourist destination information, and landmark information. ### Claim 4 (depends on 1) The method of claim 1, wherein the immersive content is selected from the database based on a time of day at the patient's current locale. ### Claim 5 (depends on 1) The method of claim 1, wherein the immersive content is selected from the database based on additional attributes associated with the immersive content including neighborhood information, and landmark information. ### Claim 6 (depends on 1) The method of claim 1, wherein the administering of the selected immersive content comprises superimposing additional cues over a video component of the immersive content adapted to pull the patient out of delirium. ### Claim 7 (depends on 6) The method of claim 6, wherein the additional cues are selected from the group consisting of a timestamp, a date stamp, and location information. ### Claim 8 (depends on 1) The method of claim 1, further comprising using noise cancellation technology to isolate a sound environment to which the patient is exposed such that the patient is only exposed to the audio component associated with the immersive content. ### Claim 9 A system, comprising: a server and database, wherein the server is configured to: select immersive content, from the database, for displaying to a patient who is experiencing delirium based on a time of day attribute associated with the immersive content; administer the selected immersive content to the patient based on a dose, by displaying said immersive content to the patient on a virtual reality device, and simultaneously playing an audio component of said content to the patient; administer a delirium test to the patient via the virtual reality device periodically, and analyze results of the delirium test to quantify a level of delirium experienced by the patient in terms of a delirium score; and determine the dose for the patient based on said delirium level, wherein said dose is a defined time for which the immersive content is to be shown to the patient. ### Claim 10 (depends on 9) The system of claim 9, wherein the server is further configured to index said immersive content based on a time of day associated with the immersive content. ### Claim 11 (depends on 9) The system of claim 9, wherein the server is further configured to index said immersive content with additional attributes selected from the group consisting of neighborhood location, city, tourist destination information, and landmark information. ### Claim 12 (depends on 9) The system of claim 9, wherein the immersive content is selected from the database based on a time of day at a patient's locale. ### Claim 13 (depends on 9) The system of claim 9, wherein the immersive content is selected from the database based on additional attributes associated with the immersive content including neighborhood information, and landmark information. ### Claim 14 (depends on 9) The system of claim 9, wherein the selected immersive content administered comprises additional cues superimposed over a video component of the immersive content adapted to pull the patient out of delirium. ### Claim 15 (depends on 9) The system of claim 9, wherein the server is further configured to use noise cancellation technology to isolate a sound environment to which the patient is exposed such that the patient is only exposed to the audio component associated with the immersive content. ### Claim 16 A non-transitory computer readable storage medium, having stored thereon, a set of computer-executable instructions that cause a computer to perform steps comprising: selecting immersive content, from a database, for displaying to a patient who is experiencing delirium based on a time of day attribute associated with the immersive content; administering the selected immersive content to the patient based on a dose, by displaying said immersive content to the patient on a virtual reality device, and simultaneously playing an audio component of said immersive content to the patient; administering a delirium test to the patient via the virtual reality device periodically, and analyzing results of the delirium test to quantify a level of delirium experienced by the patient in terms of a delirium score; and determining the dose for the patient based on said delirium level, wherein the dose is a predefined time for which the immersive content is to be shown to the patient.
