- An analysis device for gliding sport is intended to be fixed on a gliding support such as a surf, or surfboard, or a ski. These two sports are given as examples but the description can be applied to any sport in which a device slides on a liquid or solid medium. Thus, and as indicated previously, the embodiments described below will focus on surfing.
- a surfboard 1 comprises an analysis device comprising a force sensor 3 in the form of a platform for capturing forces according to 6 components: the 3 forces according to Cartesian coordinates and the 3 moments around the axes of the Cartesian coordinate system.
- This mark is defined as linked to the surfboard, where x is the longitudinal axis, y is the transverse axis and z is the vertical axis.
- less sophisticated sensors limited to capturing one or two force components can also be used for cost reasons. The counterpart to the use of such sensors is that the information collected is less rich. This can be offset by preliminary studies using the 6-component platform to determine the main components to be analyzed.
- the force sensor 3 is attached to the surfboard 1 at the interface with a user.
- the sensor 3 is preferably positioned under the front foot of the surfer because it is the main foot to direct the surf.
- the sensor 3 can also be positioned under the back foot or two sensors are installed to collect the forces of each foot.
- the force sensor is, for example, positioned under the sole of the ski boot. The force sensor thus captures all the forces generated by the user on the gliding support. It captures both the vertical and horizontal forces, front and rear, as well as the rotational torque around the 3 axes, ie on 6 axes of freedom.
- the force sensor 3 is integrated in the surfboard 1 so as to limit as far as possible the difference in position of the user compared to a non-instrumented surfboard.
- the force sensor 3 must resist the environmental elements of the surfboard 1 and in particular the marine water whose corrosion power is well known. At the same time, the possible protection of the force sensor 3 must not disturb the measurement of the forces. For example, a waterproof plastic film such as the Seaguard Flex 5400, Dickson, Wasquehal, France placed on the cover of the force sensor 3 has the advantage of not disturbing the capture of forces. Another solution is to use a force sensor intrinsically resistant to marine corrosion.
- the analysis device also comprises a position and motion sensor 5.
- This position and movement sensor 5 is intended to identify the interactions between the surfboard 1 and the wave by analyzing the dynamic behavior of the board. surfacing 1 via, for example, angular velocities and longitudinal accelerations of the surfboard. It is therefore adapted to capture the position, speed and acceleration of the surfboard in space.
- a 3-axis gyroscope such as the InvensSense ITG3200, San Jose, California
- a 3-axis accelerometer such as the ADXL345 from Analog Devices, Norwood, USA
- a magnetometer but may also consist of components that may be less performance but also less expensive such as a GPS receiver or use fewer components and, for example, be limited to a GPS receiver and a 3D accelerometer of the type used by consumer smart phones.
- a processing unit 7 is connected to the force sensor 3 and the position and motion sensor 5.
- This processing unit 7 synchronizes the data from the sensors.
- it may consist of a Mega 2560 card from Engineering, Torino, Italy which also includes an analog-to-digital converter.
- This analysis device can be divided into several locations of the glide support.
- the position and movement sensor may be composed of several elements offset from the force sensor 3 and the data processing unit 7, and this being logically connected with them, and vice versa for the others. elements of the analysis device.
- a network may be installed to retrieve and synchronize information from these two sensors and also to collect and synchronize information from other sensors.
- a camera 9 attached to the surfboard 1 is connected to the processing unit 7 by this network.
- the camera 9 is positioned to capture the image of the user, in particular his foot placed on the force sensor to advantageously allow correlations to be made between the sensed forces and the position of the user.
- the analysis device also comprises a storage memory 1 1 synchronized data and / or a transmitter 13 for transmitting the synchronized and / or processed data in real time to an analysis and visualization computer (not shown) via a wireless link. This allows the data to be used at the end of the year and / or during the exercise.
- step 21 of the electrical measurements from the sensors into numerical values representing the different physical values: forces (N), moments (Nm), velocities (ms "1 ) and accelerations (ms " 2 ) in the Cartesian coordinate system x , y, z;
- step 25 Storage and / or transmission, step 25, of all the synchronized data.
- Figure 3 thus shows the evolution of the force Fz as a function of time according to different situations.
- zone 35 the actual surfing phase starts and begins with a peak of Fz corresponding to the support of the surfer standing up. Then there is a series of support / withdrawal corresponding to the evolutions of surfing. This typically corresponds to a bending / extension taking up phase.
- FIG. 4B, 4C and 4D show as a function of time and synchronized respectively:
- FIGS. 4 correspond to the same surfing phase as that of FIG. 3, it can be seen that the search for speeding results in acceleration peaks along the longitudinal axis: the desired result is therefore well achieved.
- This device is advantageously usable for learning and improving a gliding sport by allowing a coach and the athlete to see and analyze precisely what happened during the exercise.
- step 51 Use, step 51, of the surfboard by a user to surf and record data from the sensors 3, 5 of the surfboard 1;
- Step 53 of data comparison can be based on data from a previous session or data from a session of a professional surfer (thus showing "the ideal") or finally, in the context of of a fun activity, the data of an "adversary".
- the display of evaluation and progression parameters is done in a graphical form highlighting the difference in position of the user against the position of a reference user or highlighting differences in position between different users.
- several users use the same board and all the evolutions are synthesized and put in parallel on this display.
- several users use each parallel an instrumented surfboard and all developments is reported on a common display, which can allow fun applications or competition.
- a computer program product downloadable from a communication network and / or recorded on a computer readable medium and / or executable by a processor, includes program code instructions for implementing the learning method.
- the simulation device comprises a sliding support and a force sensor fixed on the sliding support at the interface with a user, as described above.
- an actuator 61 is fixed on the gliding support and is adapted to move the gliding support in 6 degrees of freedom.
- This actuator is for example a hexapod positioner or a motion platform.
- the position and motion sensor is advantageously integrated with the actuator. It can even be deleted considering that the position of the surf is perfectly defined at any time by the positioner.
- a processing unit 63 is connected to the force sensor 3 and the actuator 61. It is adapted to modify the position of the gliding support according to the forces generated by the user and parameters of modeling an environment to simulate the result of the forces applied to the glide support by the user according to an environment programmed to simulate, for example, the shape of a wave, or the slope of a track of ski.
- the modeling is based on a predictive model making it possible to predict the behavior of the board according to the behavior of the surfer.
- This model is built from data acquisition sessions using the surfboard 1 equipped with the analysis device described above.
- This simulator also includes display screens 65 to allow to inform the user, in the most natural way possible, of the environment that has been programmed so that the user can react to it.
- the data processing unit 7 further comprises a computing unit for analyzing the data coming from the sensors in order to provide the user (the surfer or a person such as the coach) a real-time analysis of quantitative evaluation and progress information.
- the data processing step 53 consists in analyzing the data coming from the sensors of the surfboard 1 and comparing them with reference data.
- the first category of data concerns the interactions between the surfer and the board which can be of the type forces, pressures and / or support location.
- the second category of data concerns the interactions between the board and the wave which can be of the type positions, speeds, accelerations.
- the computing unit comprises a predictive model which makes it possible to predict the movement of the surfboard either from the measured data relating to the interactions between the surfer and the board, or to from the measured data relating to the interactions between the board and the wave.
- This quantitative information on the movement of the board is then compared to reference data that is grouped into a database. These reference data are obtained either from a previous session or from a session of a professional surfer. The comparison step thus makes it possible to determine the difference in position between the user with respect to the position of a reference user, thereby showing the points to be improved.
- the image of the user, in particular his foot resting on the force sensor obtained from the camera 9 is synchronized with the data from the force sensors.
- the sealed analysis device is formed by at least one coating provided with several attachment zones to be fixed on the gliding support 1.
- the force sensor 3, the position and motion sensor 5 and the data processing unit 7 are associated with a surface of coatings. When the coatings are fixed on the sliding support, they form a sealed zone for the sensors 3 and 5, and the processing unit 7.
- this coating is in the form of a foam plate with an outer surface having a relief and an inner surface associated with the surfboard. sensors 3 and 5, and the data processing unit 7.
- the outer surface thus forms a non-slip surface for the sliding operator. It can be of different shapes and sizes depending on the style of the surfing practitioner.
- the different coatings are arranged on the board to optimize the support of the practitioner.
- the sensors 3 and 5 and the processing unit 7 can be associated with a coating or several coatings.
- the invention also relates to a gliding support such as a surfboard or ski equipped with an analysis device that allows the practitioner of a gliding sport to learn and improve.
