Abstract

According to one aspect, the invention relates to a device for the surface diffusion of illuminated images to human scale, said device comprising a set of sensors (3) which can detect a body or other object close to the device, and a set of point light sources (2) which allow illuminated images to be diffused in response to the signals detected by the sensors. The device is characterised in that it comprises: a first set of plates or strips (1) on which point light sources and integrated circuits (4) for addressing the point light sources, either individually or in groups, are arranged in one or more lines, said integrated circuits being electrically connected in order to operate in a cascade manner in each line; and a second set of plates or strips (7) on which sensors (3) and integrated circuits (5) for addressing the sensors, either individually or in groups, are arranged in one or more lines, said integrated circuits being electrically connected in order to operate in a cascade manner in each line.

Claims

1. A device for the surface diffusion of illuminated images to human scale comprising:

a set of sensors suitable for detecting a body or other object close to the device;

a set of dot light sources enabling the diffusion of the illuminated images in response to the signals detected by the sensors;

a first set of plates or strips on which the dot light sources and integrated circuits are arranged according to one or more rows for addressing the dot light sources individually or in groups, the integrated circuits being electrically connected to operate in cascade mode on each row; and

a second set of plates or strips on which the sensors and integrated circuits are arranged according to one or more rows for addressing the sensors individually or in groups, the integrated circuits being electrically connected to operate in cascade mode on each row.

2. The device as claimed in claim 1, wherein the integrated circuits comprise shift registers.

3. The device as claimed in claim 1, wherein the sensors are visible radiation or infrared sensors, capacitive or inductive sensors.

4. The device as claimed in claim 1, wherein the sensors are pressure sensors.

5. The device as claimed in claim 4, wherein the sensors comprise first and second electrical contacts arranged on parallel, opposite surfaces which are intended to be placed in contact through the pressing of a body or other object on the device.

6. The device as claimed in claim 5, wherein, the first and second sets of plates or strips being separate and arranged in more or less parallel planes, the first contacts are arranged on a surface of the first strips or plates and the second contacts are arranged on a surface opposite the second strips or plates.

7. The device as claimed in claim 1, wherein the dot light sources, the sensors and the set of integrated circuits are arranged according to one or more rows on the same plates or strips.

8. The device as claimed in claim 1, further comprising a deformable, generally flat base, made from a rigid or semi-rigid material, intended to integrate the first and second sets of plates or strips and comprising a set of supports more or less perpendicular to the plane of the base and a set of flexible segments allowing the base to be deformed according to two directions of said plane.

9. The device as claimed in claim 8, further comprising a support grid intended to rest on the supports of the base and openings intended to allow the passage of the light emitted by the dot light sources.

10.
