INTERACTION DEVICE WITH A MICROCOMPUTER.

The invention relates to a device for interacting with a microcomputer, more particularly intended for beginner children with a view to the use of a microcomputer and to familiarization with computers.

A microcomputer is traditionally associated with a keyboard and a screen.

However, such a keyboard has about a hundred keys, so that it is unsuitable for very young children, both in terms of functions and mechanical level of the keys.

It implies in fact, in addition to a perfect knowledge of the letters, the numbers and the various signs appearing on the keys, also a certain agility at the level of the fingers, constituting a problem of ergonomics for the child.

Document FR-A-2 763 408 describes an interface adaptable to a computer keyboard, consisting of an auxiliary keyboard, capable of replacing the main keyboard of the microcomputer, and completely covering the upper surface of this last.

This superclavier includes a limited number of keys, and is provided with means for fixing to the main keyboard. The keys of this auxiliary keyboard are provided with organs for transmitting the driving movement at the level of certain keys of the main keyboard, so as to generate, obviously depending on the software loaded in the central unit of the microcomputer, determined reactions from the computer.

Undoubtedly, this interface allows young children to familiarize themselves with the fun aspect of microcomputers.

The object of the invention is to provide an interface with a computer, in particular by means of the keyboard associated with the computer, and more specifically with the generation of microcomputers compatible with PCs or other standards of the multimedia type.

The objective of the present invention is to optimize child-computer interaction, by combining this interactivity with toys located in the vicinity of the microcomputer, therefore of the child.

This interaction device with a microcomputer, adaptable to the keyboard thereof, is provided with sensors, capable of receiving a signal emitted by a toy or a user, and is capable of transferring, depending on the signal received, another signal. to the microcomputer.

In fact, the invention essentially consists in providing the interfacing keyboard or auxiliary keyboard constituting the interaction device, with sensors capable of picking up signals of any kind, capable of being emitted by toys, obviously provided with transmitters or even appropriate receivers, thus generating an action of the microcomputer.

These signals, as already mentioned, can be of different natures, and in particular light, sound or even radio frequency.

In the context of light signals, these can be formed by modulating the light level emitted by the light-emitting diodes for signaling from the keyboard associated with the microcomputer, or from a part of the screen, also associated with the microcomputer. .

In this hypothesis, the interaction device has photo-detectors, capable of picking up this light signal and transforming it into an electrical signal intelligible by the microcomputer.

According to the invention, the interaction device is provided with a microcontroller, intended to manage these different interaction phases.

It can also integrate voice analysis and recognition software, in order to transform the sound signals, and in particular constituted by the child's voice, into electrical signals, intelligible by the microcomputer, and therefore capable of optimizing again the interactive nature of the whole.

According to the invention, the interaction device comprises an electrical connection to the USB port, to the serial or parallel output of the microcomputer, the latter ensuring by this means its electrical supply.

It then integrates a device for shaping the received signals, integrated for example within the microcontroller, capable of making these signals intelligible by the microcomputer.

The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the example of embodiment which follows, given by way of indication and without limitation in support of the appended figures, in which: FIG. 1 is a representation schematic of the device according to the invention; 'Figure 2 is an illustration of child-toy interactivity via the overlay according to the invention; * Figure 3 is a schematic representation in space of the integration of the overlay according to the invention with a PC-type microcomputer.

The interaction device according to the invention has the general reference (2) in FIG. 1. It is fixed or placed on the traditional keyboard (1), associated with the microcomputer, of the PC type.

This interaction device (2) or superclavier, of substantially parallelepiped shape, comes to be wedged on the perimeter with the standard dimensions of the keyboard (1), and at least covers the alphanumeric block of said keyboard (1), as can be observe it well in FIG. 3, thus ensuring its protection, and preventing access by the user to this alphanumeric block. This setting has thus been represented by the four vertical arrows directed downwards.

This superclavier (2) comprises a limited number of keys (3), of larger dimensions than the keys of a traditional keyboard, and especially of various shapes (star, round, square, etc.), or even of colors. and of different textures, with the aim of making the keyboard more attractive, and above all more ergonomic, in relation to the age of the child. These keys are therefore intended to serve as intermediate means of interaction between the user and the microcomputer by means of the connection (8) described below in more detail.

Advantageously, these keys (3) are provided with a cover, carrying figurines or interchangeable patterns. These covers are therefore chosen according to the play described by the program loaded in the microcomputer.

The on-keyboard (2) therefore already has the function of selecting and limiting the number of keys accessible on the keyboard (1) associated with the microcomputer. It simplifies and makes intuitive its use, for a child starting to use computers, without his knowing how to read or write.

<Desc / Clms Page number 4>

As already said, the interaction device of the invention is intended to constitute an interface for remote control or remote operation of a program or software loaded in the microcomputer. To do this, the interaction device is provided with a signal interfacing and shaping circuit, managed by an integrated microcontroller, thus ensuring the management of the data exchange.

The various sensors or receivers are intended to allow interaction with the toys that the child uses in the environment of the computer, thus allowing interaction between the child at a distance and the program introduced in the microcomputer.

FIG. 1 shows a radio transceiver (6), for example of the RFID type (magnetic induction receivers, for short distance communication by modulated magnetic field), also capable of being replaced or supplemented by a speaker microphone, and an infrared receiver (5).

In an advanced version, such receivers are also capable of transmitting, in order to send signals understandable by the latter to the toy, in order to optimize the interactive nature of these toys. These toys are then provided with an appropriate sensor, for example of the inductive label type operating according to RFID technology.

According to an advanced version of the invention, the superclavier (2) is provided with a photodetector (9), intended to pick up a light signal emanating for example from the diodes (7), traditionally present above the numerical block of the keyboard (1 ), and signaling the locking of the numeric block, the locking of the alphanumeric keyboard in upper case mode, etc. These diodes are controlled by a program called routine of the operating system of the computer, that a game software loaded in the computer can control, in order to transmit the useful signals to an interactive animation with the keyboard (2). The photoelectric sensors (5) pick up the sequential binary signals, and these are interpreted by the microcontroller integrated in the overlay (2), which governs the emission of sound effects, for example.

Such a photo-detector can also be positioned, for example on a rod integral with said overshield (2) orientable in the direction of the screen associated with the computer, or in the center of a suction cup stuck on said screen, so as to capture part of the screen. The signals received are in the form of an intensity modulation of

la zone considérée de l'écran sous forme séquentielle, et gérée par un logiciel chargé dans l'ordinateur. Ils induisent l'émission de signaux par ledit surclavier (2) en emi direction des jouets l'environnant Comme déjà précisé, le surclavier (2) est également susceptible de réagir à la voix de l'enfant pendant le déroulement du jeu, et à distance. Il interprète et transmet les ordres énoncés par l'enfant à l'ordinateur, en utilisant la liaison USB (8). Ainsi, à proximité de l'ordinateur, l'enfant interagit avec l'ordinateur, en énonçant des commandes contextuelles en fonction du jeu. Cette fonction est optimisée par l'intégration au surclavier d'un microphone optimisé pour sa qualité de réception. Un tel microphone (6) est par exemple connecté sur le port d'entrée de l'ordinateur, par l'intermédiaire du surclavier.

the considered area of the screen in sequential form, and managed by software loaded into the computer. They induce the emission of signals by said keyboard (2) in the direction of the surrounding toys. As already specified, the keyboard (2) is also capable of reacting to the child's voice during the course of the game, and to distance. It interprets and transmits the orders given by the child to the computer, using the USB link (8). Thus, near the computer, the child interacts with the computer, by issuing contextual commands depending on the game. This function is optimized by the integration on the keyboard of a microphone optimized for its quality of reception. Such a microphone (6) is for example connected to the input port of the computer, by means of the superclavier.

According to another implementation of this advanced variant of the invention, the microphone (6) is associated with an amplification and digitization system within the superclavier (2). The sound is then transmitted in digitized form to the computer, via the USB port.

In this case, the microphone does not require a specific connection. The fidelity of the sound conversion is then guaranteed, it allows an improved recognition rate. The computer, equipped with voice recognition software, then interacts remotely with the child.

According to the invention, the interaction device or keyboard (2) is connected to the microcomputer by a removable electrical connection (8), in particular to the USB port, but such a connection is also possible at the serial or parallel output of the unit Central.

Given this connection, the interaction device (2) does not require an electrical power source since it is supplied with electricity via this electrical connection.

All the signals received or emitted by the interaction device pass through the cord (8). A signal received and identified at the level of the interaction device (2), is managed by the aforementioned microcontroller, and is converted into a digital signal, and transferred to the computer via the USB cord.

An example of application of the device according to the invention will be described below.

. volant tourné à droite ; 'avertisseur ; * vitesse N (neutre : arrêt) ; * vitesse-1 : marche arrière ; w vitesse 1 : marche avant ; 'appui sur accélérateur. In this case, it is an interactive carrier. The carrier, typically a children's tractor, is fitted with contacts (all or nothing) connected to a transmitter. They correspond to the following functions: * steering wheel turned to the left;

. steering wheel turned right; 'horn; * speed N (neutral: stop); * speed-1: reverse; w speed 1: forward; '' press on accelerator.

Depending on the degree of improvement, some of these contacts can be replaced by analog sensors, for example for controlling the steering wheel or the accelerator, optimizing the interactive nature.

les informations en relation avec leur fonction : * rotation du volant ; * utilisation de l'avertisseur ; * sélection d'une vitesse ; 'appui sur l'accélérateur. These various sensors transmit directly to the device according to the invention

information related to their function: * rotation of the steering wheel; * use of the horn; * speed selection; on the accelerator.

Thus, these interactions are characterized in the following way: The child being seated on its carrier, is able to visualize on the screen of the microcomputer its different actions: thus, by turning the steering wheel to the left, it visualizes the scrolling of the landscape towards the left on the screen. When he selects reverse, the impression of backing up materializes on the screen.

In an advanced version, three-dimensional printing can be rendered on the screen. As a corollary, the computer can emit sound effects corresponding to the different situations, and in particular the acceleration and deceleration phases, but can also emit instructions according to the actions of the child.

A racing type simulation can also be envisaged, with one or more carriers interacting with the computer.

<Desc / Clms Page number 7>

In the version where only one carrier is interacting, the child drives his carrier, which he visualizes on the screen. He races with other virtual carriers, also shown on the screen.

In the version where several carriers are interacting with the computer, each player is represented by a vehicle on the screen. The connection between the carriers and the computer is made either locally, as already described, or by internet connection.

In addition, interaction can be optimized by positioning a child on the keyboard.

When certain keys are pressed, new events are generated, such as the appearance of obstacles on the track, etc.

We therefore understand the value of the device according to the invention, in the context of optimizing the interactive nature of the assembly thus produced, quite naturally inducing the child to become familiar with computers in a fun way.
