Description

DISPLAY DEVICE AND SYSTEM FOR IMPROVING COGNITIVE, CONDITIONAL

AND COORDINATIONAL ABILITIES

TECHNICAL FIELD

The invention relates to a display device and a system comprising the display device that are adapted for improving cognitive, conditional and coordinational abilities.

The study of physical activity and cognitive skills has recently become a popular research topic, as the state of these two parameters greatly affects quality of life and performance. Performance is affected by four major variables: coordinational, conditional, emotional, and cognitive abilities or skills, and also the factors that have an influence on them. Each of these skills has a crucial and essential role in our everyday activities and also in our behaviour under competitive conditions. Development of abilities plays a key role for example in improving the performance of athletes, while it also positively affects the quality of life. The technical solution according to the invention provides aid to athletes and trainers for the improvement, development of coordinational, conditional, and cognitive abilities.

BACKGROUND ART

Certain ability development methods are focused on improving the agility of participants of training sessions. The term “agility” can for example be described by using the following words: cleverness, alertness, vividness, quick-wittedness, liveliness, briskness, quickness, swiftness, activity, swiftness, promptness, adroitness, adeptness, etc. According to a definition agility is a quick movement of the whole body in response to a stimulus, especially by changing speed or direction. Although the terms “agility” and “change of direction ability” are often used interchangeably, the latest research clearly differentiates the two. In simpler terms, agility involves reactive abilities in unpredictable environments, while change of direction focuses on mere physical abilities, and is usually tested in a pre-designed environment. An essential part of the definition of agility is that it involves a response to a stimulus, i.e. , agility includes a reactive component. This reactive component is built of several cognitive functions, such as for example: visual processing, timing, reaction time, detection, expectation. In the case of football (i.e. , soccer), for example, the reaction of a back to a sudden movement of a forward is regarded as a movement grounded in agility, because it requires that the back can make a decision as a reaction to the impulsive movement of the forward.

US 2007/0213126 A1 discloses the necessity of agility development, for example by applying coloured light sources, and by applying such a LED matrix that is capable of displaying numeric signals, colours, letters, or other visual stimuli or shapes.

According US 2016/0271447 A1 agility training is performed by applying a display device disposed on a training cone.

The signalling device according to WO 2017/041141 A1 can show different colours, where different tasks can be associated with the different colours. As it is disclosed in the document, the signalling devices can be grouped together, with one of the devices operating in “master” mode and one or more other signalling devices can be operated in “slave” mode. According to the document, each display devices can be controlled from a mobile device.

According to the technical solution disclosed in WO 2019/058246 A1 , mobile phone- controlled display units can be applied for supporting training. The display units can also be implemented as LED units capable of showing colours and coloured shapes.

US 2019/0374843 A1 discloses a technical solution wherein the training is led not by means of display devices but by utilizing colour and light signals.

In US 2020/0108291 A1 a technical solution for assessing athletes is disclosed. The document discloses a solution for implementing 3D motion tracking, while the technology of dynamic visual stimulation also appears in the document, according to which sequential LED light signals are applied for agility training.

US 6,247,674 B1 and US 2003/0070236 A1 relate to patient monitors applicable in hospitals. US 6,247,674 B1 discloses a technical solution wherein a holder tab-like securing member can be pulled out from a recess formed at the backside of the device. US 2003/0070236 A1 also discloses a hook-type attachment that can be folded and rotated out from a recess partially formed in the backside of a device. DESCRIPTION OF THE INVENTION

Figs. 1-8 illustrate the configuration of a preferred embodiment of a display device 10 according to the invention in various views. Figs. 1 and 2 illustrate the display device 10 according to the invention in two different perspective views, while Figs. 3-8 show a front view (Fig. 3), a rear view (Fig. 4), a top view (Fig. 5), a bottom view (Fig. 6), a left side view (Fig. 7), and a right side view (Fig. 8) of the display device 10.

The display device 10 according to the invention is adapted for developing cognitive, conditional, and coordinational abilities, and comprises a display unit 19 having a display member 12. In the preferred embodiment according to Figs. 1-8, the display member 12 comprises 32x32 individual illumination units, which illumination units are preferably adapted for displaying various colours. The illumination units are preferably implemented as tri-colour (e.g., RGB) LEDs, preferably surface mounted (SMD) LEDs that are preferably arranged in a square grid pattern in the display member 12. By way of example, the illumination units have a size of 3.5 x 3.5 mm and are arranged in a 6 x 6 mm grid, i.e. , the illumination units do not form a continuous surface, but in this example the adjacent illumination units are arranged at a distance of 2.5 mm from each other. Such an exemplary preferred arrangement can be seen in Fig. 3 that shows the front view of the display device 10. The advantage of display members 12 adapted for displaying various different colours is that the display member 12 is able to display not only letters, numerals, or pictograms, but these can also be displayed in various colours, which increases the amount of information that can be conveyed to the users, for example, athletes, by the display member 12.

The display unit 19 preferably comprises a frame 14 that is preferably arranged along the edge of the display member 12, and is adapted for protecting the display member 12 from potential damage. An exemplary detailed configuration of the display unit 19 and further optional structural components thereof are explained in more detail in relation to Fig. 11 .

The display device 10 comprises a housing 16 that is arranged at the backside of the display unit 19 and has a flat rear surface. The display device 10 further comprises a hanger member 20 that allows the display device 10 to be hung on an object, for example on a top edge of a board or fence of a sports ground. The hanger member 20 comprises a hanging shank 20a and a connection member 20b connected to the hanging shank 20a, wherein the hanger member 20 is attached to the housing 16 by means of the connection member 20b via a rotatable connection, and wherein the hanging shank 20a is arranged parallel to the axis of rotation of the rotatable connection.

In the display device 10 according to the invention the hanger member 20 has a first position and a second position, where the second position is reachable by rotation from said first position around the axis of rotation of the rotatable connection, and where the axis of rotation extends parallel to the rear surface of the housing 16 and spaced apart by a spacing from the hanging shank 20a. In the exemplary embodiment according to Fig. 2, the display device 10 comprises two hanger members 20 that are preferably arranged symmetrically to each other. Of the two hanger members 20 the one shown in the left of the figure is in the first position, while the hanger member 20 shown on the right is in the second position. Starting from the first position, the second position can be reached preferably by applying an approximately 90°rotation. The fundamental function of the connection member 20b is to keep the hanging shank 20a at a distance from the rear surface of the housing 16 in the second position, such that, thanks to the spacing brought about in this manner, the display device 10 can be hung on an object (for example on railings or boards of sports grounds) by applying the hanger member 20. To allow that, the axis of rotation of the rotatable connection is located at a depth, as measured from the rear surface of the housing 16, that is smaller than said spacing.

The housing 16 of the display device 10 according to the invention comprises in its rear surface a recess 22 formed for receiving a hanger member 20 that is in the first position. The axis of rotation arranged according to the invention and the housing 16 configured according to the invention enable the hanger member 20 to at least partially move behind the plane of the rear surface of the housing 16 in the first position, and this way the display device 10 can have a compact configuration.

The recess 22 preferably fully encompasses the hanger member 20 when it is in the first position, i.e. , in the first position the hanger member 20 preferably does not extend above the flat rear surface of the housing 16. Thanks to this preferable configuration, the space taken up by the display device 10 according to the invention during storage and shipping is reduced, and the display devices 10 do not bump into or entangle with each other, whereby potential damage to the display member 12 can be prevented.

To facilitate the moving of the hanger member 20, the display device 10 comprises an additional recess 24 formed in the housing 16. By reaching into the additional recess 24 it is easier to grab the hanger member 20 and to rotate it from the first position into the second position. Furthermore, the additional recess 24 also facilitates the rotation of the hanger member 20 from the second position into the first position and reduces the risk of the finger of the user of the display device 10 getting stuck or pinched between the hanger member 20 and the back portion of the housing 16.

In a preferred embodiment according to Figs. 1-8, the hanger member 20 has an L- shape, the longer stem of which is the hanging shank 20a, and the shorter leg is the connection member 20b. With an L-shaped hanger member 20, the recess 22 preferably has a rectangular configuration that corresponds to the shape of the hanger member 20.

The system according to the invention therefore preferably allows that the users of the system participate in a (training) session simultaneously in one or more groups, and that the different groups can be assigned different tasks, or identical tasks timed differently, for example with a delay relative to each other.

The system according to the invention preferably comprises more than one control centres that are adapted for controlling the same group or different groups of display devices 10. In a preferred embodiment, the system comprises two control centres that control the display devices 10, or the groups of display devices 10 of the system independent of or in cooperation with each other.

The information according to the predetermined program for example comprises colours, numbers, letters, pictograms, or a combination thereof.

In the system according to the invention, the control centre is preferably implemented in a computer, in a tablet computer, or in a smartphone.

The application of the system according to the invention in relation to football training sessions is explained below. The system comprises at least one display device 10 - preferably one to eight display devices 10 - according to the invention that can be arranged, preferably by a trainer, in an area designated for training activities. Preferably, the trainer specifies in advance the information to be displayed on the display devices 10, and also the activities that the users (for example players, participants of the training session) are expected to perform in case the given piece of information appears on the display devices. For example, the colours may represent the users, or groups of users, and the pictograms, numerals, or letters may indicate the tasks to be performed. The users’ task is to execute (based on the displayed information) the task assigned to the given piece of information displayed on the display device 10. The information displayed by the display device 10 can be made specific according to the given sport or other field of application, and, in the case of different sports, different activities to be performed can be assigned to the same displayed information.

The system according to the invention comprises, in an exemplary case, eight display devices 10 that can be arranged at arbitrary positions in or around the sports ground, at an arbitrary height, facing in arbitrary directions. The display devices 10 can for example be mounted on stands, or can be hung on the railings or boards around of the sports ground by means of the hanger member 20 of the display device 10, depending on the conditions of the location of use.

The programmable control centre of the system according to the invention is preferably adapted for executing a predetermined program that can be designed, with a timing accuracy of around one second, to correspond to the method or training methodology required by the user. The predetermined program can be applied to control all the display devices 10 included in the system according to the invention together, individually, or in groups; accordingly, the individual display devices 10 are able to operate in a mutually synchronised manner, with a given time delay with respect to one another, or even randomly.

In a preferred embodiment, the system according to the invention comprises eight display devices 10 and two control centres. During football training sessions, each of the control centres can be operated by a respective trainer. If the trainers supervise the same training session collectively, then each control centre is in a communication connection with each display device 10, i.e. , to be able to control every single display device 10 independent of whether the display devices 10 are arranged in groups or not.

However, the system according to the invention can for example be configured such that one of the control centres is in connection with only a predetermined group of the display devices 10, while the other control centre is in connection with a predetermined other group of the display devices 10, and each control centre controls only those display devices 10 that it is in connection with. This configuration enables a trainer to simultaneously lead two separate training sessions by using the same system.

The information (colours, numbers, letters, pictograms) appearing on the display device 10 according to the predetermined program is displayed in the required manner as a function of time; the predetermined program can preferably be configured by the users or their trainer.

In case display devices 10 comprising multiple display segments are applied, the display segments are able to display different pieces of information.

The system according to the invention preferably comprises one or more cameras or display devices 10 comprising a camera, which can be used for recording the movements of the users of the system. The footage recorded by the cameras can for example be evaluated automatically, by applying image processing based on machine learning, preferably after the training session. This can involve, after identifying the users of the system (the players) a personalized detection of the differences between the planned and actually performed tasks and activities, and allows for evaluating the performance of each user.

Based on the nature of the deviations from the requirements related to the exercises assigned to the information appearing on the display devices 10 detected in the course of monitoring the activities, suggestions can be made for improving the quality of performing the exercises. The deviations can be related to specific movements and/or to timing. The system equipped with cameras is therefore able to quickly sense and detect the activities carried out during a training session as a result of information displayed by the display devices 10, based on which it becomes possible to measure an information interpretation/detection process and an information detection time of the subject (user). In addition to that, based on the predetermined program, the system is preferably able to measure the quality of the carried out set of activities and the time required for it. Also, by carrying out the same series of exercises, it is possible to measure the temporal changes of the above listed parameters, for example in a form of a learning curve.

In possession of the above-described information, sports experts can receive feedback on the quality of the work performed by the users, on the efficiency of their development, and on the effects of training frequency and quality on improving the subject’s abilities. The measured data can be used by the trainer for making suggestions to the user related to the user’s further development; these suggestions can however also be generated automatically, based on a predetermined knowledge base (for example, an ontology-based knowledge base) by applying machine learning methods.

Certain preferred embodiments of the system according to the invention therefore allow that an analysis of the measured data is generated by the control centre, which analysis can be based not only on action sequences but can also be time-based, in which latter case the development and learning curves of the participants of the training sessions can also be determined. The latter allows for adapting the predetermined program contained in the control centre to the individual abilities of the participants, so the predetermined programs can include individualized training plans and individualized exercises.

In a further preferred embodiment of the system according to the invention, the control centre also enables the quasi-real-time assessment, evaluation, and analysis of the performed activities and exercises. Assessment and analysis are preferably performed by processing and evaluating camera images (video recordings). The assessment can include, on the one hand, the differences between the planned (expected according to the predetermined program) and actually performed tasks of the user, and, on the other hand, the temporal changes in performing the tasks included in the program (e.g., development, improvement, occasional). Based on this analysis, the control centre preferably generates a suggestion facilitating the further development of the user. The display device 10 and system according to the invention can effectively serve the simultaneous, coordinated development of cognitive, psychomotor, and communication skills of the users. This is because in order to perform the tasks correctly according to the predetermined program, the users are required to understand the tasks and to detect and understand the randomly specified parameters (information and instruction conveyed through colours, numbers, pictograms), which requires cognitive skills, and carry out the actions and movement sequence without errors, which requires psychomotor skills, and also the high-level performance of communication with teammates (through voice, movements, eye contact).

The display device 10 and system according to the invention can be effectively applied for improving the above-mentioned skills and abilities, and, in the case of applying a display device 10 and/or system comprising cameras, for performing video-based performance analysis and providing feedback, which allows the objective measurement of individual development and the detection of deviations from the generic development path that enables devising individual, personalized development paths.

The manner of industrial application of the invention follows from the features of the technical solution described above. As can be seen from the description above, the invention fulfils its objectives in a very advantageous manner compared to the prior art. The invention is, of course, not limited to the preferred embodiments described in detail above, but further variants, modifications and developments are possible within the scope of protection determined by the claims, for example by combining the preferred embodiments illustrated also in the figures.
