An emitting device may emit a human imperceptible signal. The signal may be received by a receiving device. The receiving device may analyze the signal to obtain digital information contained therein. The receiving device may then initiate a response action based at least in part on the digital information. Further, the emitting device may dynamically modify the human imperceptible signal based on a change to a characteristic in an environment into which the human imperceptible signal is emitted. ## Claims ### Claim 1 A computer-implemented method for utilizing a human imperceptible signal, the method comprising: detecting the human imperceptible signal, wherein the human imperceptible signal includes a hologram and a position of the hologram is dynamically modified based at least in part on a change to at least one characteristic in an environment into which the imperceptible signal is emitted, the at least one characteristic comprising a location of an object in the environment; analyzing the human imperceptible signal to obtain digital information contained in the human imperceptible signal; and initiating a response action based at least in part on the digital information. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the digital information is route guidance information specifying a path between a starting location and a destination location, and wherein initiating the response action comprises controlling navigation of an autonomous vehicle along the path. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein the digital information comprises an indication of a boundary of a parking location, and wherein initiating the response action comprises providing the indication of the boundary of the parking location as input to an autonomous vehicle parking protocol. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, wherein detecting the human imperceptible signal comprises receiving the human imperceptible signal from a mobile device. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the human imperceptible signal further includes at least one of an inaudible signal or a haptic signal. ### Claim 6 A system for utilizing a human imperceptible signal, the system comprising: at least one memory storing computer-executable instructions; and at least one processor configured to access the at least one memory and execute the computer-executable instructions to: detect the human imperceptible signal, wherein the human imperceptible signal includes a hologram and a position of the hologram is dynamically modified based at least in part on a change to at least one characteristic in an environment into which the imperceptible signal is emitted, the at least one characteristic comprising a location of an object in the environment; analyze the human imperceptible signal to obtain digital information contained in the human imperceptible signal; and initiate a response action based at least in part on the digital information. ### Claim 7 (depends on 6) The system of claim 6, wherein the digital information is route guidance information specifying a path between a starting location and a destination location, and wherein the at least one processor is configured to initiate the response action by executing the computer-executable instructions to control navigation of an autonomous vehicle along the path. ### Claim 8 (depends on 6) The system of claim 6, wherein the digital information comprises an indication of a boundary of a parking location, and wherein the at least one processor is configured to initiate the response action by executing the computer-executable instructions to provide the indication of the boundary of the parking location as input to an autonomous vehicle parking protocol. ### Claim 9 (depends on 6) The system of claim 6, wherein the at least one processor is configured to detect the human imperceptible signal by executing the computer-executable instructions to receive the human imperceptible signal from a mobile device. ### Claim 10 (depends on 6) The system of claim 6, wherein the human imperceptible signal further includes at least one of an inaudible signal or a haptic signal. ### Claim 11 A computer program product for utilizing a human imperceptible signal, the computer program product comprising a non-transitory storage medium readable by a processing circuit, the storage medium storing instructions executable by the processing circuit to cause a method to be performed, the method comprising: detecting the human imperceptible signal, wherein the human imperceptible signal includes a hologram and a position of the hologram is dynamically modified based at least in part on a change to at least one characteristic in an environment into which the imperceptible signal is emitted, the at least one characteristic comprising a location of an object in the environment; analyzing the human imperceptible signal to obtain digital information contained in the human imperceptible signal; and initiating a response action based at least in part on the digital information. ### Claim 12 (depends on 11) The computer program product of claim 11, wherein the digital information is route guidance information specifying a path between a starting location and a destination location, and wherein initiating the response action comprises controlling navigation of an autonomous vehicle along the path. ### Claim 13 (depends on 11) The computer program product of claim 11, wherein the digital information comprises an indication of a boundary of a parking location, and wherein initiating the response action comprises providing the indication of the boundary of the parking location as input to an autonomous vehicle parking protocol. ### Claim 14 (depends on 11) The computer program product of claim 11, wherein detecting the human imperceptible signal comprises receiving the human imperceptible signal from a mobile device.
