The second gesture is for example a horizontal gesture of the hand at a distance from the screen, (a scan or touch and swipe in English), to command the sending of the selected image.

Preferably, the image is transferred to a social network (for example of the facebook or twitter type) to which the user belongs.

The image can be sent directly to another vehicle or to a server landed.

FIG. 3 shows a logic diagram illustrating a variant of the method according to the invention. In this variant, the method according to the invention further comprises steps of:

5 - Acquisition (2041) and recognition of a third gesture, by the gesture recognition module (105), and

In response to the recognition of said third gesture, a step of modifying (2042) the acquired image, said modification being a function of said third gesture.

The third recognized gesture corresponds, for example, to a delimitation of a part of the acquired image. In this case, the modification of the image is a reframing of the image to the part delimited by the gesture.

According to an advantageous characteristic, the method according to the invention further comprises a step of acquiring a comment associated with the image, via an acquisition module.

The comment can be written, it is then acquired via a touch screen. The comment can also be oral, it is then acquired via a microphone. The comment is associated with the image acquired before it is sent.

) The pointing of the image area can take different geometrical shapes according to the coding of the information that one wants to transmit to its social network, for example, with the index, it is possible to delimit an image under a triangular shape to signal danger.

The device 101 advantageously comprises a dictionary of

5 shapes (eg pictograms). The forms make it possible to specify the message that one wishes to send to its social network during the transfer of the image and in the absence of linguistic messages. For this purpose, the information sharing device further comprises a database (not shown) of forms, icons, symbols, logo types in a brand code,

) including the design of shapes, colors, textures.

The decomposition of movements is done, for example for a right-handed person: delimiting and pointing the area of an image to be transferred,

- Sweep with the flat of the hand vertically to transfer pictures, texts or pictograms from right to left. The opposite is true for a southpaw.

Advantageously, the vehicle 100 comprising a geolocation module 108, the method further comprises a step of association with the acquired image of geolocation data.

The geolocation module 108 is for example GPS type. Images acquired by the process are associated with their coordinates

) GPS automatically before transmission.

According to an advantageous embodiment, the method according to the invention further comprises a step of processing the acquired image. The image processing makes it possible to estimate a pollution index from the image. This pollution index is then emitted with the image. For example, image processing

5 may consist in comparing the acquired image with a reference image representing the same scene, for example the Eiffel Tower. The image processing determines a first index associated with the reference image and a second index associated with the acquired image. The pollution index is then a function of the difference between the first and the second index.

The invention is particularly useful for transferring information to a connected automotive community such as:

- the state of urban traffic,

- the atmospheric conditions based on the shooting of his community in different points of a city,

5 - sharing his position,

- a remarkable point of the urban environment,

- the monitoring of uncivil road behavior, to report to his community.

It is also possible to use the device to send a distress signal or report a road accident or an event in the city.
