Description

The present invention relates to a mobile learning observation unit for improvement in the sciences and techniques of physical and sports activities (STAPS).

He has been known to record the physical exercises of sportsmen for purposes of learning and education. Current video techniques not only allow you to film exercises, training sessions, competitions and pedagogical sessions, but also to read movies to analyze them by scrolling frame by frame. But these known means do not allow to display almost instantaneously the images or compare them to previous records to detect defects or progress in the execution of certain techniques.

The present invention aims to remedy these drawbacks and proposes to develop a device for viewing almost instantaneously shooting individual or collective sports exercises such as collective sports (football, basketball, etc .. or individual sports (athletics, gymnastics, etc ...) to put the precise analysis of gestures or combinations of games and allow the athletes to see immediately the management they have executed but especially to improve the execution of their actions to progress in the exercise of their disc cipline, possibly comparing with recordings of other sportsmen in the same discipline.

This unit is characterized by the fact that it is complete, autonomous and mobile.

To this end, the invention relates to a mobile unit for observation and learning for the improvement in the sciences and techniques of physical and sports activities (STAPS) characterized materially by a cabinet provided with a wheeled base, in the form of a column with an accessible front face and a rear face closed by a lockable door and a set of trays, - video equipment for observation, display, reading and recording including - a fast camera, - a TV-VCR set connected to the camera, - a DVD / CD Rom digital disc player, - a CD player, - a laptop microphone, - a sound column and a microphone, - a radar and a screen. display, a sound timer, means for locking and locking the equipment in the cabinet, these means being accessible only through the lockable rear door.

The mobile unit according to the invention can be installed in a sports hall or on a sports field to be close to the athletes during exercises, so as to enable them to find immediately the recording of their exercises for them. correct immediately and make new recordings. This mobile unit also makes it possible to parse the executed gestures image by image to detect defects and correct them. This analysis can also be done in a comparative way with previous recordings or recordings concerning the execution of the same gestures by other top athletes or in the case of team games to see execution of a combination not in an absurd way deals, with the only performers of a team but with performers in real game, in the clash of two teams.

This mobile unit makes it possible to treat all individual or collective physical exercises. Thanks to the sound timer, which emits an audible signal at the end of a reference period, for example every minute, it is possible not only to record the execution of exercises but also to define exercise periods. Sound column allows the monitor to easily control the execution of exercises including for a large number of individuals (several hundred) and in large spaces (90 x 50). This sound column also allows you to rhythm the exercises with a background sound. Finally, the radar and its display screen allow for the heating in particular to measure the instantaneous speed for example in addition to a video recording for all mobiles (human or material).

This instantaneous speed can be useful for the execution of certain exercises especially if the running speed is important (hedge passage or start speed for pole vault or high jump). ).

Particularly advantageously, a mobile unit is integrated in a cabinet provided with rolling means which allows to place this unit at any place of an exercise or playing field. The front facade, mobile, for example in the form of a shutter, protects the equipment when the mobile unit is stored. This component facilitates access to equipment. These devices are themselves protected and secured by locking means that secure the equipment to the cabinet and are accessible only from the rear face of the cabinet, face itself protected by a locked door.

The outer surfaces of the cabinet can be used for display or for advertising purposes. To avoid any accident it is particularly interesting to provide the edges of the cabinet padded material for example a foam.

In the stationary position of use, the camera is advantageously placed on a bracket on the top of the cabinet. The camera can be remote controlled. It is also possible to remove the camera from its bracket and to remove it. Finally, the camera is stored in a camera housing provided for example at the bottom of the cabinet and accessible only from the rear. Thus all equipment is protected not only against shocks but also against theft.

The present invention will be described below in more detail with the aid of an embodiment shown diagrammatically in the accompanying drawings in which - Figure 1 is a perspective view of the front of the mobile unit, - Figure 2 is a rear perspective view of the mobile unit according to the invention.

According to FIGS. 1 and 2, the invention relates to a mobile observation and learning unit for improvement in the sciences and techniques of physical and sports activities (STAPS). This mobile unit consists of a cabinet 1 mounted on a base 2 with wheels 3 to move this unit on the exercise site or in the sports hall and store this unit after use. This column-shaped cabinet has a front face 4, open, bordered by two rails 5 for a roller shutter placed in a box 6 in the upper part of the cabinet. This rolling shutter goes down mounts. In the lowered position, it is preferably blocked by a lock.

The rear face of the cabinet is provided with a door 7 equipped with a locking means for example a creaton 8 with a lock 9 to block access to the rear. The door 7 may be in one piece or be completed in the lower part by a second door 10, movable as the first, possibly secured to it or capable of being detached, so as to allow access to the lower part of the cabinet without having to clear the upper part by the door 7.

This cabinet has trays 11, 12, 13, 14 for receiving video equipment and accessories. To facilitate the description of the interior of the mobile unit according to the invention, the cabinet is only illustrated by its outline and by some of its elements such as the doors 7, 10 or the shutter 6.

The mobile unit comprises video equipment comprising a camera 20 capable of being installed on a column 21 protruding from above the cabinet. The camera 20 may be oriented on a fixed lens. It can also be removed from the top of the cabinet for use as a mounted camera.

The equipment also comprises an assembly formed by a television 22 and a video recorder 23 preferably in the form of a combination combining these two devices. The television 22 and its video recorder 23 are placed in the upper position in the cabinet on the upper shelf 2 to which they are secured by locking means.

The electronic equipment also comprises a digital reader 24 and a disk drive 25. This reading equipment is placed on the tablet 12. The electronic equipment is completed by a microcomputer 26 with its screen 27, for example a microphone -laptop. This microcomputer is placed on the tablet 13 at a height facilitating access to the keyboard and control of the screen 27. Finally the equipment consists of a sound column 28 with an unrepresented wireless microphone and a radar 29 with his screen. The electrical supply of the various devices is done by pulling the terminal strip 30, connected to an extension 31 rolled. This makes it possible to connect to a relatively remote power supply.

The various cables connecting the equipment are preferably housed in a vertical chute joining the various trays 11, 12, 13, 14 at the rear of the cabinet. This chute was not represented.

The vertical edges of the cabinet, such as edge 33, are provided with a soft lining or padding, for example a foam angle, to make the vertical edges less dangerous. Finally, the various electronic devices are secured to the cabinet for example to different trays by locking means 34 represented very schematically. These locking means may be slides in which are engaged corresponding slides secured to the casings of the devices. These slides are accessible only from the rear when the door 7 is open. These slides can also be completed by locking means possibly locked by a lock equipped with a key in addition to the conviction and protection provided by the door 7.

Finally the outside, preferably on one side, the cabinet is equipped with a sound timer 36 to display a short time and signal the end of a period for example period of one minute corresponding to the execution of an exercise.

The mobile unit according to the invention is preferably installed in a gymnasium or in a gym at the disposal of teachers and students to enable them to receive real-time information on the learning, competition and training sessions. demonstrations taking place in the same place. This mobile unit makes it possible to establish an immediate communication with the outside, for example via a parabolic television antenna the images can be emitted. A connection to the Internet is also possible via the microcomputer. This equipment also allows the simultaneous reading of documents from data banks or in the form of cassettes, CD or DVD discs or software for example to model sporting behaviors of the highest level. Thus all the means necessary for a modern learning of physical activities, sports and recreation are available in a combined and interactive way.

It is also possible to connect this unit to a large screen in a viewing room or to connect it to the videoconference. Thus this unit allows to set up a pedagogy, a learning, a training and a competition assisted by multimedia.

The video camera is a semi-professional digital camera with fast shutter, preferably 1/5 to 1/11, allowing the shooting of moving objects at high speed. It allows the decomposition of the movement and the immediate restitution of images with slow motion and repetition. The combined set of TVs and VCRs not only displays the images taken by the camera, but also receives sports TV channels or plays recorded tapes or displays camcorder images in real time. The digital player 24 is equipped with a thumbwheel 241 for reading cassettes of the camcorder with an encoding of the running time of the tape in 1 / 100th of a second. One thus restores the gestures or a sport sequence image by image with stop on image and display of the time associated with each image. A simple difference of time immediately gives the duration of execution of a gesture. This, for example, is important for analyzing the passage time of a hedge for jumping at the hedge. The image-by-image display makes it possible to analyze the gesture performed by the athlete and the time associated with each image gives the execution time of the gesture possibly with upstream gestures and gestures downstream.

The portable microcomputer 26, 27 reads CD Roms and pre-established diskettes. I1 can also read live digital photos taken during the session or during the preparation phase of the teacher.

The radar 29 controls the speed of travel, for example, of the tennis service ball or volleyball. It can also measure the speed of an athlete such as the instantaneous speed of movement.

Finally, the chronometer 36 or electronic sound turntable is a giant chronometer so visible from a distance preferably of a diameter of 30 cm whose dial turn occurs in one minute. He notably times the training sessions and controls the duration of the rehearsals. It also facilitates the execution of a session with a permanent time control.
