Abstract

System for the production of inertial peripheral luminous markers, dedicated to the direction of movement or visual balance, by the peripheral visual field, in particular for a confined and mobile or apparently mobile visual environment in order to avoid disorders related to motion sickness or motion sickness and allow increased vigilance. The system consists of an inertial sensor and a lighting production system or image (s) reported or integrated into a support for the essentially peripheral visual field of one or two eyes.

Description

Inertial lighting device specific to the so-called peripheral vision designed to prevent motion sickness or motion sickness and improve alertness.

The present invention relates to a peripheral visual tracking device, reported or integrated in confined or partially confined visual environments, mobile transport cabins or simulators, screens, or other supports themselves or not mobile, to provide their users with a location Inertial visual, even of gravity, of the same nature as the inertial perceptions of internal ears in particular, but in their essentially peripheral visual fields, to bring visual information identical or close to the usual inertial perceptions (out of confinement) and to avoid or prevent thus notably any disturbance such as: anxiety, loss of alertness, stability, and motion sickness or movement in general, related in particular to divergent perceptions of the inertial balance in general with peripheral vision.

It is to enhance its efficiency by providing by the peripheral way, in the direction of movement or visual balance, one or more luminous visual marker (s) flashing real movements or conversely stability, including same type, inertial (s) as those usually provided by the fixed (terrestrial) environment, in order to reduce or avoid the various disorders induced by difference or contradiction with other inertial perceptions of the function of equilibrium, and, especially motion sickness or motion sickness.

Relative to the harm of the specific transport out of or in very low gravity usually called: the evil of the space, the absence of gravity and the weakness of the inertial information related to it is such that, for example, the fishes embedded conform their posture to the simple fixed representation of a congener. Consequently, there is every reason to propose in such a case a visual peripheral information of stability, greatly increased information or inertial substitution.

The present invention thus aims at numerous applications in the fields of virtual or augmented reality, transportation, aeronautics, nautical, automobile, railway, scientific, medical, comfort, leisure or professional, military but also zoological, zootechnical or cinematographic.

A difference in perception between sight and other essentially inertial perceptions of equilibrium arises when the individual is placed in an environment that is itself in motion, without having a real or earthly visual reference sufficient to relate existence. of his own movement. And, conversely, a difference in perception between sight and the essentially inertial perceptions of equilibrium appears when the individual is placed in an apparently moving environment, without any real or terrestrial visual reference, demonstrating the non-existence of his own movement.

Indeed, the eye perceives an environment whose apparent movement is about as immobile as it inside a mobile, for example, a moving boat cabin. At the same time, the other all inertial sensors of movement and balance starting with the inner ear, perceive different information and especially, real movements. This perception differential causes a disturbance of the equilibrium usually called equilibrium sensory conflict and notoriously: motion sickness or movement (seasickness, air, road, rail ...) also called motion sickness .

Several anti-motion sickness devices are currently commercially available, some of which are the subject of patents.

In patent application PCT / FR00 / 025698, by the same author, it is proposed in particular to combat motion sickness, on the one hand, to be provided with special glasses in that they comprise, for example, levels arranged within range. of the visual field, or, on the other hand, a device of visual wedges which translates an integrated virtual image to various supports or their periphery.

This image is produced from information obtained from gyroscope (s), accelerometer (s) or other sensor (s) and one of a logic organizing the reverse reproduction of its movement.

Difficulties of perception of this information can appear, variations of illumination of the levels in particular. The device is then slightly effective according to its insufficiently peripheral disposition, its low pregnance, the low illumination or vice versa, the glare that it can cause in night use for example ... And it finally appears too often that the possibility perception of certain fundamental parts of the image thus restored is quite inadequate and particularly in its periphery.

The present invention is essentially intended to overcome the aforementioned drawbacks of most current anti-motion sickness devices inefficient.

According to the invention, this object is achieved by a visual wedge device attached to or integrated with any support to be positioned in the essentially peripheral field of view, but remarkable in that it consists of images or scintillating or flashing lights more or less quickly and basically made available to the periphery of the eyes concerned.

In order to improve this provision of inertial horizon levels, it has therefore appeared necessary to improve the efficiency of the previous patent by an installation specifically intended for the essential attachment of strictly peripheral vision and thus, a particular organization of the device. a luminous device, more precisely designed to more strongly stall the specifically peripheral vision by the essentially unconscious visual environment rather than by the usual unsuited means, more or less dedicated to voluntary and analytical central vision.

The device according to the invention makes it possible to illuminate or produce an inertial peripheral horizon by various image means and especially lights, for example light-emitting diodes provided to the peripheral visual field. An inertial horizon is then composed of luminous elements, dots or lines for example, determining a line of visible level, maintained in permanent horizontal inertial inverse position whatever the frontal or sagittal movements of the mobile or mobiles transporting them (or simulators ) can flicker or flash for a good grip (or learning this hook).

In general, this horizon of inertia is not limited to a line, but possibly to several, to several points, or even to various forms or images that are not necessarily horizontal but whose sufficiently intermittent and thus contrasted layout allows a catch visual peripheral, inertial reference.

A preferred variation of the device according to the invention has a luminous assembly possibly remaining illuminated above this inertial, peripheral, linear, virtual horizon thus created.

This preferred arrangement of the device according to the invention makes it possible to flash or glitter these lights all together and partially, and in this case particularly those constituting the inertial horizon, peripheral, virtual.

A second preferred arrangement of the invention makes it possible to vary together or separately the light intensity of the virtual inertial horizon and possibly other lights constituting the device.

A third preferred embodiment of the invention makes it possible to vary the average height in order to adapt it to the height of the eyes of the users standing, sitting, ..., even adapted to the height of the eyes of the children in a seated position. For example, a train, bus, tram, automobile, boat, or passenger cabin equipped with seated passengers may receive such equipment providing lateral visual fields, for example at least four columns of light-emitting diodes (with for example 1 watt each and each independently controlled or dedicated) on each side inside the cars per group of seats, two or three for example, for buses or trains, that is to say in each front row, one or two columns preferably, on each side, window and corridor, a total possible for example, two, or four, per front row of four seats.

Only the contrast being taken into account in this approach, the color of the diodes does not matter: we will therefore opt for a soft white (ie a white without blue or slightly yellow, around 2700k, often referred to in the industrial language). "Warm").

The columns may optionally be held vertical simply in bars which will, for example, notched for this purpose, to accommodate and protect strings of lights, or reported or integrated into the glazing.

The lights will gladly be directed to the eyes of users and possibly obscured elsewhere so as not to interfere with other passengers.

These columns, possibly of small thickness will be arranged as necessary relative to the development, including before or in any glazed openings for example or unwound in a total or partial obscuration of such curtains. By way of example, the probable height of the columns of lights arranged at less than one meter and fifty will be approximately one and a half meters.

In such a case, 60 cm from the top, will be located, the average reference level of stability (when the mobile is stationary and flat), at the average height of the eyes of adult passengers.

In trains, (Figure 1) car equipment should not necessarily occupy all rows of seats in each direction per car.

The sensor (or sensors composed for example of one or more accelerometers) will preferably be disposed at a rather central level relative to the head of the passenger (s), perhaps simply above the middle row of a front group of passengers. four seats for example, and preferably at the greatest height, near the intermediate floor for the lower cabins mobile floor (s), or even preferably still integrated in the upper part of one of the central bars for maintaining said garlands of lights.

The logic responsible for managing the system can likewise be integrated into it.

An intermittent mobile reference light level is thus shown, roughly at the height of the eyes of the seated passengers, in the immobilized mobile and flat, and the lights located above this reference level remain willingly, more dimly lit, but not necessarily and will be able to flash or flicker alike.

Various controls can then improve the comfort and increase the effectiveness of the device. These commands, too, can be reported or integrated into one of these bars located at the edge of the access corridor.

Four controls should usefully improve the efficiency of the system: 1) Priority can be given to passengers who wish to use it, but it can still be comfortable to switch it off with a switch. 2) The most vulnerable passengers will be able to opt for an increased brightness of all the columns concerning them, and possibly even accentuated with the lowest lights. 3) The flickering glitter of the lights, especially the lower ones of all the columns concerning them will be able to be activated and variously modulated by the passengers. 4) Another important control will adjust the height of the average stability reference level (lowest light when the mobile is immobilized) up to 20 cm lower for children under 10 years. Priority before, in fact be given to the lowest eyes, especially those children (more likely), especially since the lowest option remains a minimum still satisfactory for others.

Similarly, the general principle of this device can usefully be installed in boat cabins (Figure 2), with the same possibilities to vary the intensity of light, flickering flashing etc. In the case of the columns of lights, possibly lengthened according to the distance of the passengers, their integration can be carried out on their surface or by simple indentations by folds of shallow depth in the partitions, without necessarily reaching to their fundamental integrity of security (for example sandwiches made of folded steel - mineral wool - steel), so without crossing any electrical equipment or not, or more wire. In this respect, the control of the lights can be done wirelessly.

Increasing the distance from the eyes of the passengers, or according to the variations of intensity of the ambient light, the columns will be gladly doubled or tripled or further increased, and their intensity with, for outdoor use, for example sets of columns of lights number eight in their standard version to equip a square.

Similarly, the general principle of this device can usefully be installed in lounges, cabins or cockpits of boats (Figure 2) or aircraft (Figure 1) or gliders (Figure 1), in bridges with or without external view, for example , anti-aircraft combat platforms, tank cabins, and others, with the same possibilities of varying light intensity, flickering flashing etc. The device of lights or peripheral images has the advantage of the independence relative to the information of navigation instruments, work and others, dedicated to the voluntary central vision that surrounds.

Similarly, the general principle of this device can usefully be installed in passenger cars, especially available to rear passengers (Figure 3), and other motorcycle helmets, with the same possibilities to vary the light intensity, the scintillating flashing etc ....

In addition, the general principle of this device can usefully be reported to all the level applications of the previous invention. In particular the possibility of illuminating these devices with lights whose intensity can be varied, and, by the illumination of all or part of the levels, and allow them a flickering flashing etc.

Finally, the integration of such a light system in or around screens or books with the same possibilities to vary the light intensity, flickering etc., but also in transported screens such as e-books, tablets , telephone, electronic glasses and other masks, can limit or avoid susceptibility to motion sickness precisely usually increased by reading such screens.

In the particular case of the transported screens, the background image dedicated to the peripheral vision will willingly consist of a geometrical structure of the type "parallelepiped grating (s)" possibly taking into consideration the arrangement of a horizontal ground virtual at the relative height of said screen above the ground. On the one hand the frame surrounding all or part of book or screen, claimed in the previous patent will be improved by the same possibilities to vary the light intensity, flickering flashing etc, but on the other hand, the software of Working wallpaper will likewise be improved by the same possibilities of varying in addition to the size of the frame of the various elements of the background, their luminous intensity and the glittering flashing of all or part of their different aspects etc.

The objects, features and advantages of the invention will become more apparent from their description by the claims of the present invention and its three non restrictive drawings here appended as examples.
