DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

[0030] In the annexed figures, same or functionally equivalent parts are designated with the same reference numerals. In the annexed figures, the apparatus according to the invention has been indicated as a whole with reference numeral 11. This is an apparatus for detecting, diagnosing and exercising functionalities of an individual, who is illustrated and identified in the figures with the reference numeral 13.

[0031] The apparatus 11 comprises a plurality of emitters 15 emitting optical stimuli perceivable by an individual. The emitters 15 comprise light emitters such as lamps or LEDs and may comprise also sound emitters. The emitters 15 are preferably distributed in a matrix form on a flat board 17 made of a suitable material, for instance wood or plastics. The emitters 15 can be evenly distributed at the intersections between the rows and the columns of the matrix, or they can be distributed according to other arrangements. The emitters 15 can also be located on different planes and define as a whole a tridimensional matrix.

[0032] The apparatus 11 comprises a unit 19 controlling the activation of the emitters 15. The unit 19 is programmed for activating the emitters 15 according to a predetermined sequence Q and according to at least one parameter P.sub.1, P.sub.2, . . . , P.sub.n. Depending on the spatial arrangement of the emitters 15, the activation sequence for the emitters 15 originates a different path on the plane or in space. The path is adapted to stimulate and guide eye movement of an individual who can perceive the sensorial stimuli emitted by the emitters 15.

[0033] The apparatus 11 further comprises a memory unit 21 in which predetermined activation sequences Q.sub.1,Q.sub.2, . . . Q.sub.n for said emitters 15 as well as the parameters P are stored. Each sequence is identified by a univocal sequence reference and comprises the references of a group of emitters 15 belonging to the plurality of emitters. The references of the emitters 15 of the group of emitters may consist for instance of univocal codes identifying the emitters, for example 001, 002, . . . 00n, or of spatial coordinates of the emitters, for example x.sub.1,y.sub.1, x.sub.2,y.sub.2, . . . , x.sub.n, y.sub.n.

[0034] In addition, preferably, the sequences Q stored in the memory unit 21 are classified on the basis of a grade of difficulty in performance for an individual, for instance an athlete practicing a specific sports discipline such as tennis.

[0035] The emitters 15 belonging to each sequence are arranged along a path corresponding to the eye movement to be induced in the individual user 13. The activation of the emitters 15 along a path determined by the selected sequence may further also induce displacement in space of the individual's body or part thereof.

[0036] The apparatus 11 comprises a monocular or binocular sensor 31 “Eyetracker” adapted to detect eye movements and capable of generating an electrical signal indicative of the eye movements of an individual 13. The sensor 31 is preferably of the binocular type, i.e. capable of detecting the eye movements of both eyes. The sensor 31 can be of the wireless type or wired type. In addition, the sensor 31 may be associated to the board 17 or separated from it. In other embodiments the sensor 31 may consist of glasses of the “Eyetracker” type.

[0037] The apparatus 11 comprises a processing unit 25 operationally connected to said control unit 19. According to the invention, the processing unit 25 is programmed for processing the signal coming from the sensor 31 and for selecting, depending on the value taken by said signal, the value of said at least one parameter P and a predetermined sequence out of said sequences Q stored in the memory unit 21.

[0038] In a preferred embodiment of the invention, the control unit 19, the memory unit 21 and the processing unit 25 are part of an electronic processor or personal computer.

[0039] Still according to the invention, the value taken by the parameter P and/or the predetermined sequence to be performed in a subsequent cycle of performance of a sequence are selected depending on the individual's performances in the preceding cycle. More precisely, the parameter or parameters P and/or the sequence Q of the cycle to be performed is/are selected based on the time T.sub.C, measured in the preceding cycle and elapsed between the activation of an emitter 15 and the moment at which the individual's eyes become fixed on the activated emitter 15, for instance the first “start” emitter or the last “stop” emitter of the sequence, or become fixed on another emitter 15, activated subsequently, of the sequence, for instance one of the “progress” emitters 15. Therefore, according to the invention, there is provided to measure at least one time T.sub.C, and preferably of a plurality of times T.sub.C, during performance of a sequence Q. The moment of activation of the emitter 15 is known, being associated to each sequence Q and depending on the parameter P. The time T.sub.C corresponds to the time elapsed between the activation of the emitter 15 in the sequence Q and the end of the eye movement signaled by the motion sensor 31 corresponding to the moment when the eyes become fixed on the corresponding emitter 15. The time T.sub.C depends on the initial positions of the individual's body and eyes, such positions being dictated for instance by a rule associated to the sequence Q or being random and freely established by the individual.

[0040] In the processing unit 25, the signal coming from the eye motion sensor 31 is processed for calculating the time T.sub.C. The time T.sub.Cis used by the processing unit 25 for selecting the value of the parameter P and/or the sequence Q to be used in the subsequent working cycle of the apparatus 11.

[0041] According to the invention, the processing unit 25 is programmed for selecting the parameter P and/or the sequence Q so as to detect, diagnose and exercise the functionalities of an individual 13 using the apparatus. The processing unit 25 is preferably programmed for selecting the parameter or parameters P and/or the sequence Q so as to promote progressive improvement in the visual and motion performances of the individual user. In the latter case the processing unit 25 is preferably programmed for selecting the value of the parameter P and/or the predetermined sequence Q so as to minimize the time T.sub.C.

[0042] In a preferred embodiment of the invention, the processing unit 25 is programmed for operating according to one of the following three modes. In the first mode only the parameter P is varied, whereas the sequence Q remains the same as in the preceding cycle, in the second mode only the sequence Q is varied and the parameter P remains the same as in the preceding cycle, and in the third mode both the parameter P and the sequence Q are varied. In the first mode, when T.sub.C exceeds a predetermined threshold S.sub.1 (T.sub.C>S.sub.1) the at least one parameter P determining the performing time for the sequence is varied so as to reduce the sequence performing speed and the same sequence is preferably performed as long as T.sub.C=S.sub.1. This situation corresponds to the case in which the eyes of the individual user have moved more slowly with respect to the time with which the emitters of the sequence are activated and therefore the eyes need to be trained starting from a performing speed closer to their performances. Instead, when the time T.sub.C is lower than the predetermined threshold (T.sub.C<S.sub.1), the parameter P determining the sequence performing speed is varied so as to increase the sequence performing speed and the same sequence is preferably performed until T.sub.C=S.sub.1 is reached. This case corresponds to the situation in which the individual's eyes have moved more rapidly with respect the sequence performing time. In the second mode, when T.sub.C exceeds a predetermined threshold S1, the sequence Q selected for the subsequent cycle will have a difficulty grade lower than that of the performed sequence, i.e. a difficulty more appropriate to the user's performances. Instead, when T.sub.C is lower than the predetermined threshold S1, a sequence of higher difficulty than that of the formerly performed sequence is selected. In the third mode, the functionalities of the first and second modes are combined, and preferably the parameter P and the sequence Q are selected so as to induce, in the individual 13 using the apparatus, a progressive improvement of the visual performances and possibly of the motion performances, so that T.sub.C=S.sub.1 is reached.

[0043] The apparatus 11 may further be equipped with a body motion sensor 23 capable of generating an electrical signal indicative of the variation of the position of a body movable in space and therefore of providing a signal indicative of the beginning and end of a body movement. The motion sensor 23 can be of various types and capable of providing a continuously variable signal, depending on the position taken in space, or a signal indicative of an occurred displacement of the movable body 13. The motion sensor 23 may comprise for instance an infrared sensor, an ultrasonic sensor, a pressure sensor, a gyroscope or an accelerometer or even a simple push-button or touch sensor. The sensor 23 can by of the wireless type or of the wired type. The sensor 23 may further be associated to the moving body or be separated from it. In the first instance, the sensor 23 can comprise for instance a strap for being fixed to an individual's wrist or ankle In the second instance, the sensor 23 can be fixed to a vertical wall or a horizontal surface or also be incorporated in a mat or in a cushion. The motion sensor 23 provides a signal indicative of the variation of the position of a body movable in space. The motion sensor 23 can be of various types and capable of providing a continuously variable signal, depending on the position taken in space, or a signal indicative of an occurred displacement of the movable body 13.

[0044] The sensor 23 provides a signal indicative of the variation of the position of a body movable in space to the processing unit 25 and therefore allows to calculate the time T.sub.S elapsed between the activation of an emitter 15, for instance the first “start” emitter or the last “stop” emitter of the sequence or also one of the “progress” emitters, and the moment at which the individual's movement begins or a specific movement established by the exercise which is being performed, for instance a step forward, a side jump, a hit with a tennis racket, is detected. The individual's movement is signaled by the motion sensor 23. It is clear that the time T.sub.S depends on the individual's initial position and on whether the individual is in motion or is standing still. The processing unit 25 measures the time T.sub.S and compares it with a threshold S.sub.2. The result of the comparison is used by the processing unit 25 for selecting the parameter P and the sequence Q to be used in the subsequent working cycle of the apparatus 11. The selection preferably takes place in the same ways as those described with reference to times T.sub.C . According to the invention, it is possible to provide for measuring a plurality of times T.sub.S during performance of a sequence Q.

[0045] Still according to the invention, it is also possible to provide that the selection of the parameter P and of the sequence Q to be used in the subsequent working cycle of the apparatus 11 takes place depending on the difference between the times T.sub.S and T.sub.C. This difference is indicative of the speed at which the individual makes a movement with his/her body when such movement is induced by the seeing of an optical stimulus.

[0046] Referring now to FIG. 1, there is illustrated an apparatus 11 according to a preferred embodiment of the invention. The apparatus 11 comprises a board 17 on which a plurality of emitters 15 of the light-emitting type, for instance LED emitters, are provided. The emitters 15 are distributed in a matrix form and, in the shown example, comprise four rows and eight columns. FIG. 1 refers to the starting configuration of the apparatus 11 in which all the emitters are in a deactivated condition. The individual 13 using the apparatus 11 stands in front of the board 17, in a starting position, and wears a motion sensor 23 associated to his/her right wrist. At the beginning of the working cycle of the apparatus 11, the control unit 19 performs a first predetermined sequence. The first sequence performed by the apparatus 11 when switched on may correspond to a randomly selected sequence, out of the sequences stored in the memory nit 21, or to a specific predetermined starting sequence, or to the last sequence performed by the apparatus before being switched off. Referring to FIG. 2, there is illustrated the configuration corresponding to the activation of a first emitter 15a in the sequence performed by the control unit 19. In the shown example, said first emitter 15a is the fifth emitter from the left in the first row from the bottom of the board 17. Referring to FIG. 3, there is illustrated the configuration corresponding to the activation of a second emitter 15b in the sequence. The second emitter 15b is the fifth emitter from the left in the second row from the bottom of the board 17.

[0047] Referring to FIG. 4, there is illustrated the configuration corresponding to the activation of all the emitters 15a, 15b, 15c, 15d, 15e, 15f, 15g of the sequence. In the shown example, the sequence comprises in total seven emitters and represents, on the plane of the board 17, two segments of straight line arranged at 90° to form a path having a shape like an L turned upside down. The emitters 15 are activated progressively and are maintained activated until the end of the sequence performance. In addition, the time interval elapsing between the activation of an emitter 15 and the activation of the subsequent emitter and being determined by a corresponding parameter P corresponds to a sub-multiple of the total performing time of the sequence. In other embodiments it will be possible to provide that the time intervals between the activation of an emitter 15 and the activation of the subsequent emitter are determined by corresponding mutually different parameters P and that consequently the sequence progression speed is not constant.

[0048] Referring to FIG. 5, there is illustrated a first alternative of the apparatus 11 in which the motion sensor 23 comprises a pressure sensor 23a located in a platform 27. When the platform 27 is treaded by the user's foot, the signal transmitted by the sensor 23a to the processing unit 25 is processed and the time T.sub.S elapsed between the activation of an emitter 15, for instance the first emitter 15a in the sequence Q, and the arrival of the signal at the processing unit 25 is measured and used for selecting the sequence Q and the parameter P of the subsequent working cycle of the apparatus 11.

[0049] Referring to FIG. 6, there is illustrated a second alternative of the apparatus 11 in which the motion sensor 23 comprises a pressure sensor 23b located in a push-button 29. When the push-button 29 is pressed by the hand of the user 13, the signal transmitted by the sensor 23b to the processing unit 25 is processed and the time T.sub.S elapsed between the activation of an emitter, for instance, the first emitter 15a in the sequence and the arrival of the signal at the processing unit 25 is measured and used for selecting the sequence Q and the parameter P of the subsequent working cycle of the apparatus 11.

[0050] According to the invention, the emitters 15 can have substantially any shapes and arrangements. In addition, the emitters 15 can be associated to corresponding symbols which are distributed in space and with which the individual 13 must interact when the emitters 15 in the board 17 are activated.

[0051] Referring to FIG. 7A, there is illustrated an example of board 17 in which the emitters 15 are distribute in a matrix form and represent a tennis ball. A pair of corresponding mats or platforms or vertical panels 33a,33b on which a corresponding tennis ball 35 is represented, are provided for guiding the eye or body movements of the individual's body 13 when a sequence Q of activation of the emitters 15 is performed on the board 17. For example it may be provided that upon each activation of an emitter 15 on the board 17, the individual 13 places himself alternately on one of the represented symbols 35. The symbols 35 are preferably associated to a pressure sensor of the kind described above and indicated with the reference numerals 23a or 23b.

[0052] Referring to FIG. 7B, the emitters 15 show two graphic symbols “IN” and “OUT” randomly distributed in a matrix form on the board 17. A pair of corresponding mats or platforms or vertical panels 33a,33b showing identical symbols 35 are provided for guiding the eye or body movements of the individual 13 when an activation sequence for the emitters 15 is performed on the board 17. For instance, it is possible to provide that upon each activation of an emitter 15 on the board 17, the individual 13 fixes his/her eyes or places himself/herself with his/her body, for instance with his/her feet, on the corresponding shown symbol 35, and in the latter case the symbols 35 will preferably be associated to a pressure sensor 23a or 23b.

[0053] In FIG. 7C, the emitters 15 show corresponding arrows and are distributed in a matrix form with the arrows oriented along different directions on the board 17. A corresponding mat or platform or vertical panel 33 showing a set of arrows 35 arranged in a sunburst manner is provided for guiding the eye or body movements of the individual 13 when an activation sequence for the emitters 15 is performed. For instance, it is possible to provide that upon each activation of an emitter 15 on the board 17, the individual moves his/her body and/or directs his/her eyes along the corresponding arrow symbol 35 shown on the mat or platform or vertical panel 33. In this case, too, the symbols 35 will preferably be associated to a pressure sensor of the 23a or 23b type.

[0054] In FIG. 7D, the emitters 15 show four graphic symbols corresponding, in the shown example, to the digits “1” to “4” and are randomly distributed in a matrix form on the board 17. A corresponding mat or platform or vertical panel 33 showing corresponding graphic symbols 35 is provided for guiding the eye or body movements of the individual 13 when an activation sequence Q for the emitters 15 is performed on the board 17. For instance it is possible to provide that upon each activation of an emitter 15 on the board 17, the individual places himself/herself with his/her feet on the corresponding symbol 35. In the shown example, the symbols 35 are arranged each at the four corners of the mat or platform or vertical panel 33. The symbols 35 are further preferably associated to a pressure sensor of the 23a or 23b type.

[0055] In FIG. 7E there is illustrated a configuration which is similar to the one of FIG. 7A, but in which the emitters 15 are arranged on a pair of boards 17a,17b. Each board 17a,17b comprises a row of emitters 15 which, when activated, show each a tennis ball.

[0056] In FIG. 7F there is represented a configuration of the emitters 15 which is similar to the one of FIG. 7E, but in which the emitters 15, when activated, show symbols identifying four different colors, each symbol being associated to a color name that does not match the color of the symbol. Each board 17a,17b comprises a row of emitters 15. A corresponding mat or platform or vertical panel 33 showing four graphic symbols 35 corresponding to the angles is provided for guiding the eye or body movements of the individual 13 when an activation sequence Q for the emitters 15 is performed on the boards 17a,17b. For instance, it is possible to provide that upon each activation of an emitter 15 on the board 17 the individual positions himself/herself with his/her feet on the symbol 35 corresponding to the color of the activated emitter 15 or to the color name appearing in the activated emitter 15.

[0057] Referring to FIG. 8, there is illustrated a second embodiment of the apparatus 11 according to the invention. The apparatus 11 of FIG. 8 is intended especially for training athletes practicing tennis. The apparatus of FIG. 8 is further intended especially for training service return in playing tennis. In this embodiment the apparatus comprises a plurality of light emitters 15 distributed on a vertical board 17. The emitters 15 are arranged in a cross-like pattern, the stem of the cross being defined by a single row of emitters and the arms of the cross being defined by three rows of emitters. Some of the emitters 15 have a size larger than the other ones. These larger emitters 15 are arranged for signalling to the user particular moments in the sequence. In the illustrated apparatus, the moment in which the ball is released by the rival is signaled by a first larger emitter 15′ located in the fourth position from the bottom in the sequence. The moment at which the ball is hit by the serving player is signaled by larger emitters 15′ arranged along the arms of the cross. In the shown example, each side of the arms of the cross has six larger emitters 15′ distributed in three parallel rows, two emitters 15′ for each of the three rows, alternated with emitters 15″ of smaller size with respect to the emitters 15′. Each horizontal row of emitters further comprises a central larger emitter 15′. In this embodiment, the sequences Q stored in the memory unit 21 differ in the height the ball reaches when hit, in the direction from which the ball is hit, right or left relative to the ascending trajectory along the vertical, and in the distance from the vertical. By means of the described apparatus it is possible to simulate the service in playing tennis from different heights and directions, depending on the row of emitters 15 that are activated in the arms of the cross. The heights can be for instance those typical of the strongest players in the world and the activated emitters 15 can be the left ones or the right ones with respect to the vertical ascending trajectory of the ball.

[0058] Referring to FIG. 9, there is illustrated a third embodiment of the apparatus 11 according to the invention. The apparatus 11 of FIG. 9 is intended especially for exercising individuals in driving vehicles. The vehicles can be of any kinds, terrestrial vehicles, naval vehicles or airborne vehicles. The apparatus of FIG. 9 is intended especially for training an individual's response to events that may occur when driving a vehicle. In this embodiment, the apparatus comprises a plurality of light emitters 15. In the shown example, the emitters 15 are distributed in a linear form and represent corresponding colors 43 of a traffic light device 45. In the illustrated apparatus, the event is signaled by one of the emitters 15. In this embodiment the sequences Q stored in the memory unit 21 differ in the duration of the time interval elapsing between the activation of an emitter 15 and the activation of the subsequent emitter. For instance, in the case of a traffic light device 45, the sequences Q preferably determine the duration of the green, yellow and red lights and the time intervals elapsing between the switching on of a color and the switching on of the subsequent color. Similarly to the already described embodiments, the apparatus 11 may include a monocular or binocular “Eyetracker” sensor 31 for detecting eye movements, said sensor being capable of generating an electrical signal indicative of the eye movements of an individual 13. The sensor 31 is preferably of the binocular type, i.e. capable of detecting the eye movements of both eyes. The sensor 31 can be of the wireless type or of the wired type. The sensor 31 may further be associated to the traffic light device 45 or be separated from it. In other embodiments, the sensor can consist of glasses of the “Eyetracker” type worn by the individual using the apparatus 11. The apparatus 11 is further preferably equipped with at least one motion sensor 23. For instance, motion sensors 23 are preferably associated to the wrist of the arm of a user who normally holds a steering wheel “VL” and to either of the ankles, typically the right ankle usually acting on the brake pedal “FR” and the accelerator pedal “AC”.

[0059] By means of the described apparatus it is possible to simulate different kinds of events occurring when driving a vehicle, by using emitters 15 with appropriate forms, for instance in the form of a dummy approaching the carriageway, for simulating crossing of a pedestrian, or of advancing vehicles, for simulating the presence of movable obstacles, or of any stationary objects such as buildings, plants, barriers etc., for simulating the presence of stationary obstacles.

[0060] The invention, though not being limited to this field, finds application particularly in the field of apparatuses for detecting, diagnosing and exercising the functionalities of the visual brain areas of individuals such as athletes practicing sports, especially tennis, at a competitive level.

[0061] The invention as described and illustrated may undergo several changes and modifications falling within the same inventive principle.
