Description

Learning and exercise aid to improve the human movement process

Description :

The invention relates to a learning and exercise aid for learning and / or improving the human movement sequence, in particular sport movement sequences using a video camera and at least one monitor or projector with a screen.

For learning and / or improving the human movement sequence, in particular sport movement sequences, e.g. B. when playing tennis or golf, the technical disciplines of athletics, such as discus throwing or shot put, but also during ballet dancing and theater, there are various learning aids in the literature. Especially in golf, a lot of money is spent on this, e.g. B. for golf lessons with a golf instructor or for other technical aids, a large number of which are available on the market. The golf swing is not a natural movement, it only works naturally for people who have worked on their swing for years and who do it as a matter of course. To achieve this, a complicated sequence of movements of the physical limbs, especially the legs, arms and hands is required. All phases of the movement must be for fit an optimal swing path of the club head. The same applies to other sports. In order to learn to play golf consistently well, it is important to have all movements run correctly from the response to the end position. To do this, you have to know the successive phases, ie the sequence of movements, exactly, i.e. have a picture of them in your head. However, the beginner never executes the movements as he believes to do and therefore needs constant corrections. For this reason, it is known to record the movement sequence when swinging a golf club with a video camera on a tape. The teacher can then use the recordings in the form of a video analysis to show the student any errors in his movement.

It is also known to use a video camera to perform the ideal movement, e.g. B. of a teacher to record on a tape. The movements of the student are then recorded on another tape. The recorded movements can then be viewed on two screens and compared. With the help of sensors, the two movement sequences can be synchronized and superimposed on the screens, so that the slightest deviations between the two movement sequences can be seen (WO 88/07735).

A learning aid for the movement sequence when swinging a golf club is known from US Pat. No. 3,353,282. In this known device, an image of the golf instructor is projected onto a coated mirror when a golf club is swinging. The student stands in front of the mirror and can use a reference point take the same position as the teacher. He can now either memorize the teacher's swing or follow the teacher's swing movements simultaneously.

All known learning and exercise aids have the disadvantage that the user cannot watch these aids while exercising their sporting movement sequence. To avoid this disadvantage, it is e.g. B. in ballet dancing or theater, known to perform the movements in front of a play gel. But this is with a sporty movement sequence, e.g. B. when hitting a golf ball or when hitting a tennis ball, this is only possible with difficulty, since on the one hand the operator sees himself only in mirror image and on the other hand the head has to move away from the ball and towards the mirror so that a stroke corresponding to reality is not carried out can.

Devices are also known with which distant images can be viewed on miniature monitors. In order to bring the monitors as close as possible to the eyes, they are arranged in a housing that can be attached to the viewer's head by means of a holder. The monitors can be viewed through eyepiece lenses, which can be adjusted using adjustment devices and adapted to the eye relief of the user (DE-OS 36 28 458 and DE-OS 38 29 011). These known devices are for viewing stereoscopically displayed objects and movements as three-dimensional television pictures on miniature monitors. Also known is a device with which images recorded by a camera are projected onto a screen. The screen and the projector are in a helmet sitting on the viewer's head (US Pat. No. 3,916,094). With this device, the user can simultaneously view a control desk and the surrounding images recorded by a camera. These known devices are mainly used in defense technology. These devices are not suitable as learning and exercise aids for learning and / or improving the human movement sequence, in particular sport movement sequences.

It is the object of this invention to provide a learning and exercise aid for improving the human movement sequence, in particular sport movement sequences, whereby the user can view his own movement sequence during execution and, if necessary, improve it in order to achieve an optimal result.

This object is solved by the features of claim 1.

In this way it is achieved that the person carrying out a physical movement can watch himself at the same time and not mirror-inverted at the time of the exercise. In addition, he has the opportunity to observe himself from different perspectives by changing the camera position. Although he has a precise idea of how the physical movement sequence has to be carried out, the actual movement sequence can deviate considerably from the optimal sequence because he cannot view the execution itself at the moment of exercise. In particular when learning and practicing sporting movements, such as B. when swinging a golf club, the subject matter of the invention is very advantageous since the user can see himself while swinging the golf club. He can therefore follow the instructions of the teacher directly to his swing movement. So he sees whether the theory of the movement sequence corresponds to practice. If not, he can improve his movements accordingly. By means of the holder, the housing with the monitor arranged therein is held on the head in such a way that, in the working position, the adjustable eyepiece lenses which are connected to the monitor via reflex mirrors are located directly in front of the user's eyes. The holder can have the shape of a temple or be designed like a helmet. An eyepiece lens is advantageously provided for each eye. The eyepiece lenses can be adjusted to the eye relief of the user by means of an adjusting device. The focus of the eyepiece lenses is carried out via an eyepiece adjustment. The monitor image is perceived enlarged by the viewer due to the reflex mirrors arranged in the housing. The monitor image is advantageously visible as a partial area in the field of vision of the eyepiece lenses, so that the user sees his movement sequence in the monitor and his immediate surroundings during exercise. This advantage also exists when the video image is projected on a transparent screen, since the viewer sees the surroundings and himself on the screen at the same time. The image transmission from the video camera to the monitor or projector can take place by cable or wirelessly, with wireless transmission being preferred, since the freedom of movement is not restricted. In the case of transmission by means of a cable, the video camera takes over the power supply for the device according to the invention. If necessary, an amplifier of the video signal can be used. In the case of wireless transmission, the device according to the invention is equipped with its own power supply. In front of the eyepiece lenses, eyecups are provided on the housing, so that the image on the Monitor is not affected by incident light. With the help of a computer and a corresponding program, the ideal sequence of movements for the student can advantageously be shown on the monitor. The images created by the computer are synchronized with the images from the video camera. This has the advantage that the student or practitioner can also follow the instructions given by the teacher at home.

Exemplary embodiments are shown in the drawings and are described in more detail below.

In the illustration according to FIG. 2, the transmission from the video camera 4 to the monitor 2 takes place wirelessly via a transmitter 6 and a receiver 7. A transmission cable 15 is provided between the receiver 7 and the monitor 2. Figures 3 and 4 show the housing 1 with the bracket 3 attached to it, which can be home-like or temple-like. The monitor 2, reflecting mirror 8 and the electronics 9 are arranged within the housing 1. Eyepiece lenses 10 are provided on the housing 1, the focusing of which takes place via eyepiece adjustments 11. In the area of the eyepiece lenses 10, eyecups 12 are arranged which protect the viewer's eyes from incident light. The eyepiece lenses 10 can be adjusted to the distance between the eyes of the viewer by means of an adjusting device 13. It is conceivable here that an eyepiece lens can be displaced horizontally by a known mechanism or that both lenses - as is known with binoculars - can be adjusted via a joint. A cable connection 14 is provided on the housing 1 for the transmission cable 5. FIG. 5 shows a further embodiment, a projector 16 and a transparent screen 17 being arranged in the housing 1. The images transmitted by the video camera are projected onto the transparent screen by the projector.
