The system comprising: a fire panel (180); one or more fire detectors (114) configured to detect a fire in each of the one or more rooms; a fire panel (180) in electronic communication with each of the one or more fire detectors (114), the fire panel (180) being configured to determine evacuation information in response to whether a fire is detected in each of the one or more rooms; and one or more hologram systems (120) in electronic communication with the fire panel (180), wherein each of the one or more hologram systems (120) is configured to generate a hologram in the one or more rooms to convey evacuation information. ## Claims ### Claim 1 A system for directing an emergency evacuation within a building composed of one or more rooms, the system comprising: a fire panel; one or more fire detectors configured to detect a fire in each of the one or more rooms; a fire panel in electronic communication with each of the one or more fire detectors, the fire panel being configured to determine evacuation information in response to whether a fire is detected in each of the one or more rooms; and one or more hologram systems in electronic communication with the fire panel, wherein each of the one or more hologram systems is configured to generate a hologram in the one or more rooms to convey evacuation information, wherein the hologram is a dynamic image of a human being presenting the evacuation information by stating audibly where the nearest exit is located, wherein audible instructions are provided by a speaker and the hologram is synced with the speaker to make it appear that the dynamic image of the human being is talking when the evacuation information is presented. ### Claim 2 (depends on 1) The system of claim 1, wherein: the hologram system is configured to adjust at least one of an intensity and a color of the hologram in response to attributes of the smoke detected. ### Claim 3 (depends on 1) The system of claim 1, further comprising: one or more human presence detectors in in electronic communication with the fire panel, wherein each of the one or more human presence detectors are configured to detect a location of a person in the one or more rooms. ### Claim 4 (depends on 3) The system of claim 3, wherein: the one or more human presence detectors are configured to detect a location of a person through a wireless communication with a user device configured to be carried by the person. ### Claim 5 (depends on 4) The system of claim 4, wherein: the user device is a card, wherein the card is configured to receive an alert from the one or more fire detectors and activate an alarm based on the alert to notify a person in possession of the card whether the person is on a safe path or an unsafe path. ### Claim 6 (depends on 4) The system of claim 4, wherein: the wireless communication is Bluetooth. ### Claim 7 (depends on 4) The system of claim 4, wherein: each of the one or more human presence detectors is configured to transmit the location of the person to the fire panel. ### Claim 8 (depends on 7) The system of claim 7, wherein: the fire panel is configured to transmit the location of the person to a first responder device. ### Claim 9 A system for directing an emergency evacuation within a building composed of one or more rooms, the system comprising: a fire panel; one or more fire detectors configured to detect a fire in each of the one or more rooms; a fire panel in electronic communication with each of the one or more fire detectors, the fire panel being configured to determine evacuation information in response to whether a fire is detected in each of the one or more rooms; and one or more human presence detectors in in electronic communication with the fire panel, wherein each of the one or more human presence detectors are configured to detect a location of a person in the one or more rooms, wherein the one or more human presence detectors are configured to detect a location of a person through a wireless communication with a user device configured to be carried by the person, wherein the user device is configured to receive an alert from the one or more fire detectors and activate an alarm based on the alert to notify a person in possession of the user device whether the person is on a safe path or an unsafe path, wherein the user device is a card. ### Claim 10 (depends on 9) The system of claim 9, wherein: the wireless communication is Bluetooth. ### Claim 11 (depends on 9) The system of claim 9, wherein: each of the one or more human presence detectors is configured to transmit the location of the person to the fire panel. ### Claim 12 (depends on 11) The system of claim 11, wherein: the fire panel is configured to transmit the location of the person to a first responder device. ### Claim 13 (depends on 9) The system of claim 9, further comprising: one or more hologram systems in electronic communication with the fire panel, wherein each of the one or more hologram systems is configured to generate a hologram in the one or more rooms to convey evacuation information, and wherein the hologram is a dynamic image of a human being presenting the evacuation information by stating audibly where the nearest exit is located, wherein audible instructions are provided by a speaker and the hologram is synced with the speaker to make it appear that the dynamic image of the human being is talking when the evacuation information is presented. ### Claim 14 (depends on 13) The system of claim 13, wherein: the hologram system is configured to adjust at least one of an intensity and a color of the hologram in response to attributes of the smoke detected. ### Claim 15 A method of directing an emergency evacuation, the method comprising: detecting a fire in one or more rooms using one or more fire detectors; activating one or more holograms within at least one of the one or more rooms; determining evacuation information in response to whether a fire is detected in each of the one or more rooms; and conveying evacuation information using the one or more holograms, wherein each of the one or more the holograms is a dynamic image of a human being presenting the evacuation information by stating audibly where the nearest exit is located, wherein audible instructions are provided by a speaker and the hologram is synced with the speaker to make it appear that the dynamic image of the human being is talking when the evacuation information is presented. ### Claim 16 (depends on 15) The method of claim 15, further comprising: detecting attributes of smoke in at least one of the one or more rooms; and adjusting at least one of an intensity and a color of the hologram in response to attributes of the smoke detected. ### Claim 17 (depends on 15) The method of claim 15, further comprising: detecting a person within one of the one or more rooms using a human presence detector; and determining a location of the person within the one of the one or more rooms. ### Claim 18 (depends on 5) The system of claim 5, wherein: the card comprising at least one of a buzzer or an LED light, wherein the buzzer is configured to vibrate to indicate whether the person in possession of the card is on a safe path, and wherein the LED light is configured to illuminate to indicate whether the person in possession of the card is on a safe path. ### Claim 19 (depends on 9) The system of claim 9, wherein: the card comprising at least one of a buzzer or an LED light, wherein the buzzer is configured to vibrate to indicate whether the person in possession of the card is on a safe path, and wherein the LED light is configured to illuminate to indicate whether the person in possession of the card is on a safe path.
