Abstract

There is provided systems and methods for performing actions based on light signatures. An exemplary system includes a light source, a light detector, a non-transitory memory storing a plurality of light signatures and a hardware processor. The hardware processor executes an executable code to illuminate, using the light source, a target object with a first light, collect, using the light detector, a second light being a reflection of the first light by the target object, match the second light with one of the plurality of light signatures, and perform an action in response to matching the second light with the one of the plurality of light signatures.

First claim

What is claimed is:

1. A system comprising:
a light source;
a light detector;
a non-transitory memory storing a plurality of dynamic light signatures; and
a hardware processor executing an executable code to:
illuminate a first target swath of a printed medium with a first light, wherein the illuminating is performed in response to a user shining the first light from the light source on the first target swath of the printed medium, wherein the first target swath depicts a first object;
collect, using the light detector, a reflection of the first light reflected by the first target swath;
match the reflection of the first light with one of the plurality of dynamic light signatures stored in the non-transitory memory by identifying color values of the reflection of the first light relative to the one of the plurality of dynamic light signatures;
determine, based on and in response to matching the reflection of the first light with the one of the plurality of dynamic light signatures indicative of the first target swath of the printed media, another one of the plurality of dynamic light signatures that is associated in the non-transitory memory with the one of the plurality of dynamic light signatures indicative of the first target swath of the printed media, wherein the another one of the plurality of dynamic light signatures is indicative of a second target swath depicting a second object, and wherein the second object depicts a key for the first object;
cause a playing back of at least one of an audio or a video associated with the one of the plurality of dynamic light signatures, in response to matching the reflection of the first light with the one of the plurality of dynamic light signatures, wherein the audio or the video asks the user to find, in the printed media, the key for the first object; and
illuminate the second target swath of the printed media with a second light that results in obtaining a second reflection of the second light by the second target swath that matches the another one of the plurality of dynamic light signatures, wherein the illuminating of the second target swath is performed in response to the user shining the second light from the light source on the second target swath in response to the audio or the video asking the user to find, in the printed media, the key for the first object.

2. The system of claim 1 , wherein the light source includes a red light emitting diode (LED), a green LED, and a blue LED, and the light detector includes a white light detector.

3. The system of claim 1 , wherein the first target swath includes ink and fluorescent ink, wherein the light source includes an ultraviolet light source and a white light source, wherein the light detector includes a red light detector, a green light detector, and a blue light detector, wherein the first target swath both emits and reflects light towards the light detector, and wherein the light detector is configured to detect emitted and reflected light by the first target swath.

4. The system of claim 1 , wherein the light detector includes at least one of a photo diode or a photo transistor.

5. The system of claim 1 , wherein the one of the plurality of dynamic light signatures includes a red value, a green value, and a blue value.

6. The system of claim 1 , wherein the matching of the reflection of the first light is within a visible spectrum and further comprises matching the reflection of the first light within the visible spectrum with a range of the plurality of dynamic light signatures within a variance of the reflection of the first light within the visible spectrum.

7. The system of claim 1 , wherein the illuminating of the first target swath includes sliding the light source over the first target swath.

8. The system of claim 1 , wherein the first light is within a visible spectrum and the second light is not within the visible spectrum.

9. The system of claim 1 , wherein the color values include a red value, a green value, and a blue value.

10. The system of claim 1 , wherein the light detector measures the reflection of the first light within a visible spectrum without capturing an image of the first target swath.

11. The system of claim 1 , wherein the reflection of the first light is a direct reflection of the first light reflected by the first target swath.

12. A method for use with a system including a light source, a light detector, a plurality of dynamic light signatures stored a non-transitory memory and a hardware processor, the method comprising:
illuminating a first target swath of a printed medium with a first light, wherein the illuminating is performed in response to a user shining the first light from the light source on the first target swath of the printed medium, wherein the first target swath depicts a first object;
collecting, using the light detector, a reflection of the first light reflected by the first target swath;
matching, using the hardware processor, the reflection of the first light with one of the plurality of dynamic light signatures stored in the non-transitory memory by identifying color values of the reflection of the first light relative to the one of the plurality of dynamic light signatures;
determining, based on and in response to matching the reflection of the first light with the one of the plurality of dynamic light signatures indicative of the first target swath of the printed media, another one of the plurality of dynamic light signatures that is associated in the non-transitory memory with the one of the plurality of dynamic light signatures indicative of the first target swath of the printed media, wherein the another one of the plurality of dynamic light signatures is indicative of a second target swath depicting a second object, and wherein the second object depicts a key for the first object;
causing, using the hardware processor, a playing back of at least one of an audio or a video associated with the one of the plurality of dynamic light signatures, in response to matching the reflection of the first light with the one of the plurality of dynamic light signatures, wherein the audio or the video asks the user to find, in the printed media, the key for the first object; and
illuminating the second target swath of the printed media with a second light that results in obtaining a second reflection of the second light by the second target swath that matches the another one of the plurality of dynamic light signatures, wherein the illuminating of the second target swath is performed in response to the user shining the second light from the light source on the second target swath in response to the audio or the video asking the user to find, in the printed media, the key for the first object.

13. The method of claim 12 , wherein the one of the plurality of dynamic light signatures includes a red value, a green value, and a blue value.

14. The method of claim 12 , wherein the matching of the reflection of the first light is within a visible spectrum and further comprises matching the reflection of the first light within the visible spectrum with a range of the plurality of dynamic light signatures within a variance of the reflection of the first light within the visible spectrum.

15. The method of claim 12 , wherein the illuminating of the first target swath includes sliding the light source over the first target swath.

16. The method of claim 12 , wherein the first light is within a visible spectrum and the second light is not within the visible spectrum.

17. The method of claim 12 , wherein the color values include a red val
