DRAWING AND PAINTING DEVICE OF RELIEF DRAWINGS FOR BLIND AND PERSONS WITH MANUAL MOTOR DIFFICULTY

SECTOR OF THE TECHNIQUE

S

The present invention is comprised within the sedor dedicated to typhotechnology in particular, as well! as to those industrial sectors that develop products for any type of disability. Intended for educational applications and especially in devices designed to improve the quality of life of people with blindness, visual impairment or manual motor difficulty.

BACKGROUND OF THE INVENTION

15 20

The state of the art includes traditional writing devices consisting of marking with a punch a sheet of paper on a semi-rigid surface following a template. The writing through these systems must be done in reverse. Once it has been written by punching and turning the paper, you can read the Braille correctly. These are extremely complex writing systems, making many mistakes by having to write in reverse, not being able to verify if the writing is correct until the time to turn the paper. In the case of making mistakes, the existing correction method consists of crushing the punched area, creating this procedure confusion in the reading since sometimes it is not clear if it is a marked or unmarked point.

25 30

Positive tracing devices are known for blind users, marketed under the name of DraftsMan of the American Printing House for the Blind, Inc. The work area is covered by a rubber plate. The special plastic sheet is placed on this base surface. Pressing lightly with a pen or pen, any drawing can be made, obtaining the positive relief strokes. They represent a good solution to the realization of continuous strokes, although these special plastic sheets are required, which makes their use more expensive. The invention recommended in this document uses conventional paper sheets for drawing, which is especially good for the use of this device in developing countries. Likewise, other devices are known in which copies of a Braille text are made, previously defined with some punches and subsequently,

with rollers pressure is created on the punches, thus stamping the

paper.

On the other hand, in 1954 the Spanish patent ES0213494 was filed in favor of Don Luis

Roca Ros with Kun apparatus title that allows the blind to obtain relief drawings

s

direct and contiguous stroke ~. This drawing device is based on the stamping of

a sheet of paper pressed between two points located on the inner faces of a

element as a clamp in "U ~ which has at one of its ends a handle for

your control This device uses this clamp to match the points of

stamping but presents difficulty in its use when the surface on which it

10

want to draw is wide, since the arms of the clamp must be at least as long

as half of the drawing surface forcing the tool from the opposite side,

this circumstance complicates the retention of the sheet by means of elements such as tweezers or

hot paper, necessary for tensioning the paper.

R. Oonovan describes a board on which templates are placed in relief with

drawings so that the blind can color them using a scented paint that

directly grabs from a container with his fingers. The board has a system that

recognizes pre made templates and a voice synthesizer that tells the blind man what

Template is about and what color you should use. Does not allow drawing and its color differs

twenty

clearly of the invention recommended.

WO 20131088204 patent entitled "System to develop drawing skills

in people with visual limitations, consisting of a drawing surface and a

writing system "of the inventor Luz Alexandra Zapata Zuluaga, is about a

25

board consisting of two surfaces, a semi-rigid one that has a panel of

foam on which to make negative embossed strokes with a pencil

rounded and another hard part in which to color the drawings. In practice, the

stamping on a padded surface on a sheet of conventional paper

It allows you to generate positive strokes, as is easy to verify, by resorting to

30

manufacturers to the use of sheets of plastic material to induce this defonnación.

In addition, do not penntte the simultaneous coloring of the strokes as well as limit your performance to

the surface of the foam zone does not have the means to offer indication to the

user modeling their learning, from which it follows that this invention differs from the

presented in this report.

35

The state of the art does not contemplate a technical solution as described in this patent, which includes different aspects that are considered appropriate to achieve compliance with the expectations of the sector. The innovation included in this patent helps facilitate drawing for people with visual and / or motor disabilities

5 manuals, while stimulating fine motor skills, so necessary in the learning process.

OBJECT OF THE INVENTION

The object of the present invention is to provide blind or visually impaired people with a device that allows them to make relief paths on a conventional paper, with positive geometries that can be interpreted with the fingertips directly. The device allows you to color the path to help people with visual disabilities interpret it. The pen or pen holder

15 colors to the body of the tracing and painting device has been conceived so that a person with motor problems in the hands, who has difficulties in grasping a pencil

or conventional marker, you can easily generate a drawing thanks to having means to locate this drawing element in addition to presenting ergonomic considerations designed for this group.

DESCRIPTION OF THE INVENTION

The present invention consists of a device for drawing and painting drawings in

relief for degas or visually impaired people as well as an instrument of

drawing for people with manual motor disabilities that allow generating a

S

stamping on conventional paper. The employment of this plotter offers the

possibility of stamping points, as well as making continuous strokes

in any direction of the work plane generating a positive relief with which

Represent any drawing. These qualities give it an application in different

areas, both in their training, professional, or as a means of expression

10

artistic, whether you have a disability or not. Versions are planned in

that this route is colored as an aid in its interpretation to people with

visual impairment, this possibility provides an integrative approach to your employment

together with people with normal vision. This circumstance is especially important

both in schools and in our homes.

The device has two elements between which the sheet of paper is held, a body

Bottom of the paper sheet and a main body that we will place

on top of this, the retention and positioning of both elements with respect to the

Sheet of paper is made using at least one magnet in each of these elements. He

lower body has a laminar shape and has on its face contact with the blade

twenty

a hemispherical protuberance that emerges on the face of contact with the sheet of paper and

which constitutes one of the stamping elements. Said lower body comprises the

less a magnet that, in cooperation with the main body, generates the

attractive force that holds the sheet of paper.

To be able to make the strokes the subject sheet is placed, either directly on a board

25

or a table by conventional means such as the use of adhesive tape or

by attaching it to a table or folder using at least one clamp. After this I know

Place the lower body under the sheet of paper and the upper body on it.

The upper element, main body, has at least one magnet parallel to the sheet of

paper and to the lower body that can be arranged in a magnet holder element that

30

it is allowed its vertical displacement within the main body approaching

or moving the magnets away from both bodies by conventional means such as

displacement thanks to an adjustment thyme. The main body or upper element

presents, for stamping, a contact surface coinciding with the

stamping element of the lower body, the contact between both surfaces of

stamping is done by actuating a button that provides vertical displacement of the described contact surface; In this way, when the button is operated, the stamping by deformation of the paper sheet occurs.

The magnetic field generated by the pairs of magnets located in both bodies is arranged so that attractive forces are generated between them, at the same time this attractive force redirects both bodies so that their stamping points are coincident.

Versions are planned in which the layout can be colored simultaneously, this is especially useful for people with visual impairments. In order to carry out this coloring, the device has means for accommodating a coloring tool such as a conventional pen or marker in a body integral to the button that has a cylindrical cavity whose end is constituted by the stamping surface that has an opening to through which the tip of the pen or marker emerges. The coloring tool is allowed to move vertically so that with the stamping pressure its tip does not deteriorate, so when the button is pressed, the coloring will first be carried out and immediately after the stamping will be carried out, for this the path of the The button must allow the tip of the coloring tool to be emeated freely but not to touch the paper.

Versions are provided in which the coloring tool can be retained in the cavity that contains it by conventional means such as a clip or a thyme, this fixing of the tool is of interest when, for example, it is not intended to make a relief stroke if not only coloring, a fact that can be carried out using only the upper body, when used by people with manual motor disabilities, who have as it is known difficulties to properly grasp a pencil or marker; In order to facilitate the manipulation of the device by people with manual motor disabilities, versions are provided in which the device has means to ensure its best grip or grip such as the use of a strap or e-strap that seizes the device. , surrounds the user's hand or wrist.

The device has means to detect its position and displacement with respect to the sheet of paper as well as the strokes made to be interpreted in an external device such as a personal computer, Tablet or Smartphone. From these external devices you can generate tools for learning and e-inclusion as! how to facilitate the work of the trainers and expand the training resources of the students. The means to achieve the detection of the position and displacement of the

device are constituted by conventional systems of extensive use in the

electronics industry, as a triangulation system formed by the combination of

Ultrasonic and infrared sensors that determine the position of the graphic tool, this

system can be replaced by other systems of proven effectiveness such as the

s

image capture through a paper surface camera and interpretation

of its variations with the movement as it is done in an optical mouse

conventional, or others based on the use of accelerometers and gyroscopes. He

device has the sensors and means described to perform the positioning and

reading of the plot, the data coming from these is interpreted by at least one

10

microprocessor, stored in at least one memory and transmitted by means

wireless such as Wifi or Bluetooth to the external device, be it a personal computer,

a T ablet or a Smartphone. The device presents means to provide information to the

user of the movements suggested by the external device software, these

means may include independently or combined signals generated by

fifteen

actuators that can be tactile. vibratory, acoustic or luminous, in this way

Indicates to the user the direction and direction of the movement to be performed. The

actuators that provide information to the user are known in the industry, of this

way to provide the tactile signals requires at least one element that changes

position so that the blind person can detect it with touch, these means

twenty

they consist of a joystick-like actuator preferably located at the top

of the tracing and painting device; This actuator can move along the X axis

as well as the Y axis when having either micromotors or electromagnetic systems

for their movement, these actuators provide information from the external device to the

user of where to move to make a certain path, they are also

25

possible other solutions incorporating four buttons with movement capability in

the vertical axis whose activation also indicates the direction and direction to the user. At

In case of vibratory signals, the device will present a vibrating actuator

conventional as a micromotor with an eccentric load whose excitation pattern

will mark the indications for the user, this vibratory pattern is frequently used

30

by the blind in different devices such as watches. The indicators or actuators

acoustics can be materialized by means known as buzzers or the

incorporation of a speaker. To provide the user with information through a code

luminous, the device has at least one light source like a LEO diode, that is

Especially useful for people with partial visual impairment.

35

The fact that the device presents these interactive actuators, helps a blind person to draw an object that he does not know yet, guided by the software that sends information to the actuator of where the user should draw, thereby expanding the current resources of Special education centers as well as allowing users to practice in their homes in a guided and comfortable way.

DESCRIPTION OF A PREFERRED EMBODIMENT

A preferred embodiment is cited by way of example, being independent of the object of the invention the materials used in the manufacture of the device for drawing and painting relief drawings for the blind, the methods of application and all the accessory details that may arise, as long as they do not affect their essentiality. A preferred embodiment of the device for drawing and painting embossed drawings for the blind, visually impaired and / or people with some manual motor difficulty is proposed.

The tracing and painting device allows positive stamping of continuous dots or strokes on a conventional paper as well as the coloring of these strokes, for this purpose it has a lower body (5) of laminar form comprising at least one magnet (9 ) embedded inside, as well as a stamping element (8) formed by a small protrusion of a substantially spherical shape that emerges from the lower body itself. Figures 2 and 3.

It also has a main body (2) comprising on the one hand a magnet holder (10) that houses at least one magnet (9), Figure 4, the magnets are arranged in a plane parallel to the sheet of paper (6) on the one that we want to make the stamping and the lower body, this can be clearly seen in Figure 6. Both the magnets located in the main body and those found in the lower body will generate an attractive force that will imprison the paper located between both bodies subsequently allowing printing, since these are arranged by guiding their polarity to generate the attraction between upper and lower body, as will be explained below.

The device has means to regulate the attraction between the upper and lower set of magnets by means of conventional systems that allow the relative displacement of some magnets against others, such as the use of an adjustment thyme (16) with its corresponding nut (17) which moves vertically, thanks to the displacement guides (11), to a magnet holder element (10) inside the main body (2) of the device, varying this distance will therefore vary the electromagnetic field and can adjust it to different paper thicknesses or facilitate the separation of the device from the sheet of paper (6) without damaging it.

To be able to carry out the stamping, cooperation with the stamping element (8) of a contact surface (18) on the other side of the paper sheet is necessary. This contact surface is located on the button (1) available to the device. This push-button (1) is allowed to move with respect to the vertical axis of the tracing and painting device and is operated at will by the user, who by pressing it will bring the printing surface (18) into contact with the printing element (8) located in the lower body, since these contact points are aligned. As a result, permanent deformation will be generated on the sheet of paper, which in the case that the device is accompanied by a translational movement in the drawing area will generate a continuous stroke as long as the button (1) remains activated. Conventional means such as the placement of an elastic spring (15) have been provided for the recovery of the button after its activation.

The device allows the coloring of the strokes (23), for this it has means to house a painting element (4), such as a colored pencil or conventional marker. These means consist of a recess in a body integral to the Pusher or in this case of a cylindrical nature that has an opening (14) for the introduction of the coloring element, the end of the pencil or marker with which to paint the strokes emerges through an outlet opening (12) located on the stamping face and preferably aligned and concentric to the stamping point. The painting element is allowed to move on the vertical axis within the expected cavity, in this way when we press the button, the point is first colored and stamping is performed without suffering the tip of the pen or marker, since it rises slightly with the contact with the sheet of paper. Versions are provided in which the coloring element is fixed to the cavity that contains it by conventional means such as a clip or squeeze (13) by means of a thyme.

When it is intended to make colored strokes without these having relief, it is sufficient to remove the lower body (5) to draw freely without having to overcome the frictional force exerted by the magnets. Versions are planned in which the pushbutton is interlocked and it is not necessary to put pressure on it to draw. This mode of use is especially useful for people who have manual motor deficiency and have, as is known, great difficulties in grasping an element of drawing.

The tracing and painting device object of this preferred embodiment has means to detect its positioning with respect to the sheet of paper (6) as well as the strokes made to be interpreted in an external device such as a computer

Personal, Tablet or Smartphone. This pennite generate learning tools and

On the other hand, improve the e-inclusion of people with these disabilities.

For this, the tracing and painting device has a conventional optical system

which records, through variations of image captures using a camera

(22) of the surface of the paper sheet, the position and displacement of the device.

This optical system of proven efficiency is the one used by optical mice

conventional. The information from the positioning system is

interpreted by at least one microprocessor and transmitted by wireless means

such as Wifi or Bluetooth to the external device, be it a personal computer, a Tablet or

10

a smartphone The device presents means to provide information to the user of the

movements suggested by the external device software, these means can

include tactile, acoustic or vibratory signals, thus indicating to the user the

direction and direction of movement, these means in this preferred embodiment

consist of an oscillating actuator (19) as a joystick located at the top

of the tracing and painting device. Figure 7. This actuator can move along

of the X axis as well as the Y axis when having either micromotors or systems

electromagnetic for its movement, as mirrors do for example

electric cars, these actuators are known in the electronics industry,

providing information from the external device to the user of where it should go
