The following specification particularly describes the nature of this invention and the manner in which it is performed:
FIELD OF INVENTION:

The present invention relates to the field of interactive workout devices. The present invention provides an improved visual target assisted workout device. Moreover, the present invention also provides an improved visual target assisted workout device that projects an image as visual targets and is used either indoors or outdoors.

The present invention claims the priority to the parent application 202221001096. The present invention is an improvement of the invention disclosed and claimed in the complete specification of the patent application number: 202221001096 (main application).

BACKGROUND OF INVENTION:

During the present era of busy and stressful lifestyle, many people turn towards aerobic exercises to maintain their physical and mental fitness. Exercise is one of the important parts of lifestyle modification. Exercise is known to reduce weight gain, obesity, muscle mass maintenance, reduce fatigue, boosts cardiovascular system, improves lung health, improve energy levels, and helps prevent or reduce certain chronic health conditions. Exercise also improves mental health by reducing anxiety, depression, and negative mood and by improving self-esteem and cognitive function. Moreover, exercise provide antioxidant protection, delay the sign of aging, helps brain health and boosts memory.

Daily physical workout is also important for the athletes and sportsperson to practice their daily drills and improve themselves. Many a times, users prefer to own certain equipment or register themselves for the online classes for their daily workouts. Multiple Gymnasium facilities are also available where the laymen/ athletes get proper equipment and train with the help of professional trainers. However, these methods get tedious or boring after a while and reduce the consistency of the users. They always face a constant need to stimulate their mind and body through creative and innovative forms of exercise. Therefore, it is easier to make exercise a regular part of lifestyle if you enjoy/have fun doing it. Moreover, the athletes cannot get the detailed report and analysis (SWOT analysis) of their skills such as agility, reflexes and stamina while working out on their own or in the gymnasium.

Although different types of interactive machines are available in the market, most of them fail to specifically interact with the users in real-time in the manner of providing visual targets and making the machine user-friendly. Many of conventionally available machines prefer physical targets like cones and pods which decreases the flexibility of target positions and number of drills. Some of the conventionally available interactive exercise machines also use additional lenses and wall projectors to project the targets which ultimately makes them more expensive.

Therefore, there is a need to provide an interactive exercise machine that interacts with the user in real-time in the manner of providing visual targets, is used by a layman or an athlete for a target assisted workout wherein the targets are the image projected by a light source instead of the physical targets, without the need of a lens or wall projector and thereby, making it affordable and compact.

PRIOR ART AND ITS DISADVANTAGES:

A US patent application US6430997B110 discloses a system and method for tracking and assessing movement skills in multidimensional space. The invention provides an accurate stimulation of sports to quantify and train performance constructs by employing sensing electronics for determining, in essentially real time, the player's three-dimensional positional changes in three or more degrees of freedom (three dimensions); and computer-controlled sport specific cuing that evokes or prompts sport specific responses from the player that are measured to provide meaningful indicia of performance. The sport specific cuing is characterized as a virtual opponent that is responsive to, and interactive with, the player in real time. The virtual opponent continually delivers and/or responds to stimuli to create realistic movement challenges for the player.

However, the invention does not provide a machine that provides visual targets to the user and determines the position of the user and track their movements. This invention also fails to eliminate the need of a projecting screen or a wall to project the laser target. In addition, this invention fails to capture the form of the user while performing the workout. Moreover, this invention fails to detect taps based on distance feedback from the laser point. This invention also fails to enable independent self-rotation property of the laser’s orientation. Furthermore, this invention fails to allow multiple players to engage in drills simultaneously. Besides, this invention fails to provide repositioning of LiDAR / sensor as LiDAR is no longer aligned with laser beam. Additionally, this invention fails to enhance alignment flexibility feature.

Another such US patent application US2022074716A1 provides a target system that detects the location of a projectile disposed within a target and subsequently alter an image being displayed on the target in response to the location of the detected projectile. The target system includes a sensor, an image source, a portable electronic device, and a computing device. The sensor is positioned on the target to detect the location of the projectile on a face of the target. The image source project an image onto the face of the target. The portable electronic device receive input from a user to dictate the image(s) displayed on the target. The computing device is communicatively coupled to the sensor, the image source, and the portable electronic device and cause the target system to detect the location of the projectile and subsequently alter the image displayed on the target in response to the location.

Although the invention described here mentions the image being displayed as a target, it fails to provide a visual target to the user without the need of a projecting screen or a wall. This invention also fails to provide an interactive exercise machine that determines and track the position of the user. In addition, this invention also fails to provide an interactive exercise machine that analyzes the agility and reflexes of the athletes and provide them with their detailed skill analysis report. Moreover, this invention fails to detects taps based on distance feedback from the laser point. This invention also fails to enable independent self-rotation property of the laser’s orientation. Furthermore, this invention fails to allow multiple players to engage in drills simultaneously. Besides, this invention fails to provide repositioning of LiDAR / sensor as LiDAR is no longer aligned with laser beam. Additionally, this invention fails to enhance alignment flexibility feature.

• The conventionally available machines fail to provide a visual target assisted workout device.
• Most of the prior arts fail to provide a visual target assisted workout device that projects visual targets for the user.

In the present invention, significant modifications have been made to the mounting and operation of the LiDAR or distance sensor. The sensor is now mounted on the Y-axis, enabling it to rotate independently in degrees (theta). The movement is in all direction as continuous motion or motion specified for the motor to move at 360 degrees. The LiDAR or distance sensor is mounted on Y-axis and independent movement of laser beam on X-axis.

Unlike the invention disclosed in parent application, where the sensor was aligned with the laser beam's direction, the updated sensor is now independent from laser point and looks directly at the laser point from the bottom. This allows the sensor to provide tap detection through distance feedback, eliminating the need for alignment and calibration with the laser. Moreover, the LiDAR's horizontal orientation enhances its performance and accuracy.

An addition in the present invention is to mount the LiDAR on the Y-axis alongside the main assembly, allowing it to self-rotate independently. This alternative mounting feature provides flexibility in the sensor placement while maintaining the LiDAR's focus on the laser point. The angle at which distance data is determined depends on the position of the Y-axis motor, which is under the control of the controller. There is no specific angle required for determination of distance since LiDAR or distance sensor mounts at any degree but most preferably LiDAR mounting is done parallel to the ground. This enables precise and dynamic tap detection based on the LiDAR's self-rotation.

Furthermore, the improved present invention enhances the alignment flexibility. As the LiDAR is mounted below the laser and aligned using the Y-axis motor and laser dot's axis, the precise alignment of the laser and the LiDAR becomes less critical. This feature contributes to the system's overall accuracy.

Moreover, the improved present invention introduces a multi-player capability in the self-rotation sensor version. Multiple players participate in drills simultaneously by using separate laser pointers, while a single LiDAR sensor captures the entire 360-degree field of view multiple times per second.

WORKING OF PRESENT INVENTION
The detailed stepwise working of the improved present invention is explicated herein. The improved present invention works simultaneously and parallelly, and thus provides a substantially efficient visual target associated workout device.
• Switching on the device: The present visual target assisted workout device has an ON/OFF switch which is used to turn on the device.
• When the device is switched on, the power supply (124) turns on the Controller (109) and the power is supplied to other component parts such as light source (103), sensor (104) and plurality of motors (106, 107).
• Connecting the input means: After turning on the device, the user connects the Input means (111) to the Controller (109) through wireless means (116). The user then provides inputs through the Input means (111). Said inputs are in the terms of providing name/s of the user/s, selecting the device and the drill which is supposed to be played. Said drills are selected on the basis of number of targets during the workout, time duration of the workout or the difficulty level of the workout.
• Selecting the parameters: The parameters to be selected are pre-fed in the Storage means (110) or it is also be selected as per the choice of user through the input means (111).
• After the selection of the drill, the projection means (102) gets signal from the Controller (109) to provide the output. The Light source or laser beam (103) and sensor or LiDAR (104) arranged in different positions gets activated as per the inputs provided through the Input means (111) to the Controller (109).
• Projecting the visual target: The Light source (103) projects the visual targets which provide directions to the users. Said visual targets serve as an indicator to the user as to where the user is supposed to reach. Said visual targets are pursued by the users performing the workout.
• The light source and sensors are arranged in different orientation where light source is only mounted on the holder and LiDAR is connected at the bottom of the device arranged above the stand/ground.
• The light source (103) and the sensor (104) are connected to plurality of motors in different orientation, wherein Motor X (106) is responsible for moving just the laser and the laser beam whereas Motor Y (107) is responsible for moving both laser and LiDAR together. Motor X and Motor Y are held by the holder (105) which defines the position of the light source. The controller (109) provides inputs to said plurality of motors, Motor X (106) to rotate between 0-270 degrees and Motor Y (107) to rotate 0-360 degrees to project at the desired position.
• Herein, LiDAR is placed in same plane as Y-axis angle in which the laser is being projected. The holder holding the laser moves the laser target to different distance in the same plane of axis. The LiDAR continuously checks the change in flux and also the distance at which the laser is being projected. Once both the distance and the flux parameter match with the required distance, an athlete is detected which moves to another position.
• Tracking user’s position: Sensor continuously scans all the direction at 360 degrees while arranged at different position from light source. This continuous movement of LiDAR mounted on the Y-axis alongside the main assembly enables self-rotation movement independent of the laser’s orientation. LiDAR is placed at an angle where the laser is projected and once the user reaches the point, the flux parameter increases. Once both distance and angle of detection matches with the distance and angle of the laser, then the projection moves towards another point with the help of motors X and Y.
• When the user reaches the target, sensor (104) only communicates with Motor Y whereas Motor X is responsible for communication with laser and the laser beam. Herein, Motor X (106) to rotate between 0-270 degrees and Motor Y (107) to rotate all direction i.e., 0-360 degrees to provide self-rotation to the holder (105) through inputs from the controller (114) to project the next visual target.
• Generating the data: The sensor (104) determines the distance travelled by user during the workout and the time taken to travel that distance. The sensor (104) also determines if the user has reached the target and send inputs to the light source (103) through the controller (109) to project the next visual target.
• Transmitting the data: The data regarding the time taken and the time taken to travel their distance is stored in the storage means (110) and is transmitted to the input means (111) through the wireless means (112).
• The input means (111) computes the acceleration and velocity of the user during the workout. The faster the user runs towards the visual target, more intense the workout.
• Accessing the data: The user access said data through the input means (111) connected to the present device (101).
• The Video capturing means (114) when turned on, captures the form of the user during the workout. It analyses the movement of the user that is moving towards the projected target. Said captured videos are then stored in Storage means (110).
• Processing means (115) is connected to the Storage means (110) to gain access to the previously captured videos by the video capturing means (114). The captured videos of the user are further compared and analyzed by either the processing means (115) or the input means (111).

WORKING EXAMPLES

Table 1:
Distance travelled before stepping on visual target Flux before stepping on visual target Distance travelled after stepping on visual target Flux after stepping on visual target
Parent application 5.4 meter 130-140 5.2 meter 200-220
Present invention 8 meters 80-90 5.2 meter 300-350

From above table 1, Parent application stated that distance travelled before stepping on the visual target is 5.4 meters as projected by LiDAR with change in flux of 130-140 whereas, the present invention states that distance travelled before stepping on the visual target is 8 meters as projected by LiDAR with change in flux of 80-90.

On the other hand, parent application stated that distance travelled after stepping on the visual target is 5.2 meters as projected by Laser with change in flux of 200-220. Whereas, the present invention states that distance travelled after stepping on the visual target is 5.2 meters as projected by Laser with change in flux of 300-350.

Therefore, conclusion is drawn that detection range before stepping on the visual target on the present invention has increased to 8 meters due to mounting of LiDAR in Y-axis for detecting maximum distance as compared to parent application. Also, change in flux for the present invention is more stable and easier to filter than parent application. Here, filter out includes filter of detecting whether the user has stepped on the point or not. Therefore, the present invention enhances the accuracy, usability and versatility of the improved visual target assisted workout device.

As illustrated in Fig. 5A-5C, readings of 360-degree LiDAR are represented as dots in point coordinate axis which are grouped and denoted by red colour circle in the illustrated figure of 5A-5C Here, red circle shows the foot placement. Therefore, the path taken by the athlete as well as the stride length with the detection of foot through the LiDAR is directly traced and used further for the analysis.

NOVELTY COMPARISION BETWEEN PRESENT INVENTION AND PARENT APPLICATION THAT LEASDS TO IMPROVEMENT OF THE INVENTION:

The parent application discloses a visual target associated workout device that is used either indoors or outdoors. It discloses a light source (laser beam) and sensor (LiDAR) which are positioned in the same holder as well as booths projection is in the same parallel manner. Herein, both LiDAR and laser beam are placed together in the holder which is operated with Motor X and Motor Y while the whole holder moves with other components of invention. Whereas in present invention, laser beam is only mounted on the holder and LiDAR sensor is connected at the bottom of the device just above the stand or ground. Motor X is responsible for moving the laser and laser bean while Motor Y is responsible for both laser and LiDAR movement. Laser point and FOV (field of vision) of LiDAR looks in the same direction of the projection but not at the same point. This eliminates the need for calibration between the laser and sensor.

Moreover, the present invention offers an additional mounting option for the LiDAR which is mounted on the Y-axis alongside the main assembly, enabling independency factor of self-rotation on the laser's orientation in degrees (theta) within a polar coordinate system. This mounting feature also provides flexibility in sensor placement while maintaining the LiDAR’s focus on the laser point. Therefore, this modification enables precise accuracy as well as dynamic tap detection based on the LiDAR self-rotation. Whereas, the parent application fails to facilitate the above-mentioned features such as self- rotation property as well as enabling alignment flexibility for LiDAR sensor. Hence, present invention facilitates more precise accuracy and usability than invention involved in parent application.

Furthermore, said present invention also facilitates multiplayer capability in the self-rotation sensor version.
