Real-time messaging system for an image display device
View Patent ↗A real-time messaging system for an image display device is provided. One disclosed embodiment includes an image display device including a light source and an image-generation device configured to receive light from the light source, and in response, generate an image. The image display device may further include a projection lens configured to display the image on a viewing surface. The image display device may also include memory and a processor operatively coupled with the memory to receive a command message sent to a select group of image display devices in real-time via a network, and upon recognizing the command message, display an alert image.
1. An image display device comprising:
a light source;
an image-generation device configured to receive light from the light source, and in response, generate an image;
a projection lens configured to display the image on a viewing surface;
memory; and
a processor operatively coupled with the memory to receive a command message sent to a select group of image display devices in real-time via a network, and upon recognizing the command message, display an alert image,
wherein the image display device is further configured to interrupt a presentation mode of displaying a presentation image, and to adjust one or more display settings of the presentation image.
2. The image display device of claim 1 , wherein the image display device is further configured to actuate a visual signal.
3. The image display device of claim 1 , wherein the image display device is further configured to actuate an audio signal.
4. The image display device of claim 1 , wherein recognizing the command message includes recognizing a command line interface prefix indicating a print text command.
5. The image display device of claim 1 , wherein the command message includes command line interface commands indicating one or more parameters of the alert image.
6. The image display device of claim 1 , wherein the image display device is further configured to receive a power command in real-time via the network, the power command changing the image display device from a powered-off state to a powered-on state.
7. The image display device of claim 1 , wherein the alert image comprises instant image data.
8. The image display device of claim 7 , wherein the instant image data comprises display information depicting at least one of the following: instruction messages, public announcements, weather alerts, meeting time periods, emergency warnings, facility alerts, or lockdown situation alerts.
9. The image display device of claim 1 , wherein the alert image is viewable by a viewer of the image display device without action on the part of the viewer.
10. The image display device of claim 1 , wherein the alert image is actuated by an administrative device.
11. The image display device of claim 1 , wherein the one or more display settings include text color, background color, aspect ratio, or text size.
12. An image display device comprising:
a light source;
an image-generation device configured to receive light from the light source, and in response, generate an image;
a projection lens configured to display the image on a viewing surface;
memory; and
a processor operatively coupled with the memory to receive a command message sent to a select group of image display devices in real-time via a network, and upon recognizing the command message, display an alert image,
wherein the image-generation device generates stored image data before the processor recognizes the command message.
13. The image display device of claim 12 , wherein after the processor recognizes the command message, the image-generation device generates the alert image.
14. The image display device of claim 12 , wherein the stored image data is a presentation.
15. The image display device of claim 12 , wherein the stored image data is a video.
