Projection on a vehicle window
A system includes a camera aimed externally to a vehicle, a window of the vehicle, a projector positioned to project on the window, and a computer communicatively coupled to the camera and the projector. The computer is programmed to, upon receiving data from the camera indicating a first person outside the vehicle, instruct the projector to project an image on the window depicting a second person inside the vehicle.
1. A system comprising:
a camera aimed externally to a vehicle;
a window of the vehicle;
a projector positioned to project on the window; and
a computer communicatively coupled to the camera and the projector;
the computer being programmed to, upon receiving data from the camera indicating a first person outside the vehicle, instruct the projector to project an image on the window depicting a second person inside the vehicle.
2. The system of claim 1 , further comprising a speaker directed externally to the vehicle and communicatively coupled to the computer.
3. The system of claim 2 , further comprising a microphone inside the vehicle and communicatively coupled to the computer, wherein the computer is programmed to, upon receiving the data from the camera indicating the first person outside the vehicle, apply a modification to a voice sound detected by the microphone, and instruct the speaker to play the modified voice sound.
4. The system of claim 3 , wherein the modification includes deepening the voice sound.
5. The system of claim 3 , wherein the computer is programmed to, upon receiving the data from the camera indicating the first person outside the vehicle, instruct the speaker to play a stored audio recording while playing the modified voice sound.
6. The system of claim 2 , wherein the computer is programmed to, upon receiving the data from the camera indicating the first person outside the vehicle, instruct the speaker to play a stored audio recording.
7. The system of claim 1 , wherein the window is tinted.
8. The system of claim 7 , wherein the image depicts the second person as a silhouette.
9. The system of claim 1 , wherein the computer is programmed to, upon receiving the data from the camera indicating the first person outside the vehicle, instruct locks of the vehicle to lock.
10. The system of claim 1 , further comprising a light on an exterior of the vehicle and communicatively coupled to the computer, wherein the computer is programmed to, upon receiving the data from the camera indicating the first person outside the vehicle, instruct the light to illuminate.
11. The system of claim 1 , wherein the computer is programmed to, upon receiving the data from the camera indicating the first person outside the vehicle, store image data of the first person of the data from the camera.
12. The system of claim 1 , wherein the computer is programmed to, upon determining that the first person is a recognized person, refrain from instructing the projector to project.
13. The system of claim 1 , wherein the image depicts the second person as a different person than occupants of the vehicle.
14. The system of claim 1 , wherein the computer is programmed to, in response to a risk score being less than a risk threshold, refrain from instructing the projector to project.
15. The system of claim 14 , wherein the computer is programmed to determine the risk score based on a location of the vehicle.
16. The system of claim 14 , wherein the computer is programmed to determine the risk score based on a current time of day.
17. The system of claim 14 , wherein the computer is programmed to determine the risk score based on a number of mobile devices proximate to the vehicle.
18. The system of claim 14 , wherein the computer is programmed to determine the risk threshold based on occupants of the vehicle.
19. The system of claim 18 , wherein the computer is programmed to determine the risk threshold based on a number of the occupants of the vehicle.
20. The system of claim 18 , wherein the computer is programmed to determine the risk threshold based on personal attributes of the occupants of the vehicle.
