Abstract

A virtual display with motion synchronization (“VDMS”) device using one or more arrays of light sources for displaying messages. The VDMS device may include a motion sensor to detect and measure movement of the VDMS device, and synchronization circuitry configured to synchronize the light emission of the individual light sources in the arrays with the movement of the VDMS device. The VDMS device may also include a self-contained power source and a control unit and interface that allow the user to program the messages that are displayed by the VDMS device, as well as memory that stores user messages.

Claims

1. A virtual display with motion synchronization (“

VDMS”

) device for displaying messages, the VDMS device comprising;

at least one motion sensor;

synchronization circuitry in signal communication with the at least one motion sensor; and

an array of light sources in signal communication with the synchronization circuitry that are configured to display messages, wherein the array of light sources emits light that forms a message responsive to signals received from the synchronization circuitry.

2. The VDMS device of claim 1, wherein the array of light sources includes at least one line array of light emitting diodes (“

LEDs”

).

3. The VDMS device of claim 2, wherein the at least one motion sensor is a low-g accelerometer.

4. The VDMS device of claim 3, wherein the low-g accelerometer further includes a standard peripheral interface (“

SPI”

).

5. The VDMS device of claim 2, wherein the at least one motion sensor is a rate gyroscope.

6. The VDMS device of claim 2, wherein the synchronization circuitry is configured to receive input signals from the at least one motion sensor, and in response produce signals that are transmitted to the array of light sources to generate a message that is displayed by the VDMS device.

7. The VDMS device of claim 6, wherein the synchronization circuitry is configured to receive control information and data from a wireless connection to the VDMS device, wherein the control information and the data are utilized in forming the message.

8. The VDMS device of claim 7, wherein the VDMS device further includes memory in signal communication with the synchronization circuitry.

9. The VDMS device of claim 6, wherein the synchronization circuitry is configured to receive control information and data from a wired data upload connection to the VDMS device, wherein the control information and the data are utilized in forming the message.

10. The VDMS device of claim 9, wherein the VDMS device further includes memory in signal communication with the synchronization circuitry.

11. The VDMS device of claim 2, further including a handgrip attached to the VDMS device that allows a user to impart motion to the VDMS device.

12. The VDMS device of claim 2, further including a self-contained power source.

13. A method for producing messages using an array of light sources positioned in a virtual display with motion synchronization (“

VDMS”

) device, the method comprising;

imparting motion to the VDMS device to define a display area in which the message will be displayed;

producing signals with a motion sensor responsive to the motion imparted to the VDMS device;

transmitting the signals generated by the motion sensor to synchronization circuitry connected to the light sources; and

generating signals with the synchronization circuitry that are transmitted to the light sources,

wherein the signals transmitted to the light sources cause the light sources to flash and generate a message in the display area.

14. The method of claim 13, wherein the motion sensor is a low-g accelerometer.

15. The method of claim 14, wherein the array of light sources includes at least one line array of light emitting diodes (“

LEDs”

).

16. The method of claim 15, wherein imparting motion to the VDMS device includes moving the VDMS device at a velocity such that the VDMS device is not visible to the human eye.

17. The method of claim 16, wherein the message generated by the flashing LEDs in the display area appears to the human eye as a steady image.

18. The method of claim 17, wherein the message generated in the display area is predetermined by a user of the VDMS device.

19. The method of claim 18, further including receiving control information and data from a wireless connection to the VDMS device, wherein the control information and the data are utilized in forming the message.

20. The method of claim 18, further including receiving control information and data from a wired data upload connection to the VDMS device, wherein the control information and the data are utilized in forming the message.
