[0029] In one embodiment of the present invention, the UE 104 includes, but not limited to, a processor 202, a display unit 204, a sensor 206, and a memory 208. For the purpose of description and explanation, the description will be explained with respect to one processor 202 and should nowhere be construed as limiting the scope of the present disclosure. In alternate embodiments, the system 200 may include more than one processor 202 as per the requirement of the network.

[0030] As per the illustrated embodiment, the processor 202 is configured to fetch and execute computer-readable instructions stored in the memory 208. The memory 208 is configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed for navigating within the VR ecosystem 100. The memory 208 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as disk memory, EPROMs, FLASH memory, unalterable memory, and the like.

[0031] In order for the system 200 to navigate within the VR ecosystem 100, the processor 202 includes one or more modules. In an embodiment, the one or more modules may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 202. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways.

In other examples, the processor 202 may be implemented by electronic circuitry.

[0032] In an exemplary embodiment, the UE 104 is placed inside the HMD device 102. The HMD device 102 includes a slot that could be opened and where the UE 104 could be placed inside the slot. In such scenarios, the user 106 navigates through the VR environment using at least one of, but not limited to, actuation of physical buttons placed on the HMD device 102, navigating using head tracking, and / or eye gaze mechanism that is operated by the user’s eye movements. In another exemplary embodiment, the UE 104 will be communicatively connected to the HMD device 102 and the user 106 navigates through the VR environment using navigation controls available in the UE 104. In yet another exemplary embodiment, the HMD device 102 will be a standalone device that could perform functions that would enable the user 106 to navigate through the VR environment. In an embodiment, the UE 104 is one of, but not limited to, any electrical, electronic, electro-mechanical or an equipment and a combination of one or more of the above devices such as smartphones, virtual reality (VR) devices, augmented reality (AR) devices, laptop, a general-purpose computer, desktop, personal digital assistant, tablet computer, mainframe computer, or any other computing device.

[0033] In an embodiment of the present invention, the processor 202 includes, but not limited to, a filter unit 210. The filter unit 210, in one embodiment, is a low pass filter that attenuates the high frequency components of a spectrum while passing the low frequencies within a specific range.

[0034] In one embodiment of the present invention, the sensor 206 in the UE 104 is an accelerometer sensor and / or a gyroscope sensor that captures a translational and / or a rotational movement of the user 106 while the user 106 is wearing the HMD device 102 having the UE 104. The translational and / or the rotational movement, collectively defined as a movement, of the user 106 includes, but notlimited to, walking, running, hopping, jumping, swinging and squatting, that are performed by the user 106 while wearing the HMD device 102. In an exemplary embodiment, while the user 106 performs at least one of the movements, the UE 104 inside the HMD device 102 shakes. The shaking motion triggers the sensor 206 inside the UE 104 and causes the sensor 206 to generate electrical signals. The electrical signals generated is a movement data that is fed into the filter unit 210 for attenuating noises generated along with the movement data.

[0035] The filter unit 210 of the processor 202 is configured to receive the movement data generated by the sensor 206, when the user 106 performs the movement while wearing the HMD device 102 including the UE 104. The filter unit 210 would attenuate noises above a certain cut-off frequency to produce a filtered data. The filtering of the movement data is done to cut-off electrical signals or frequencies that are generated when the user either intentionally or abruptly shakes the UE 104. In such a scenario, there is some movement generated that the user 106 might not want to translate to the virtual environment. For example, the user 106 while wearing the HMD device 102 over the user’ s head or while holding the HMD device 102 on the user’s hand, intentionally shakes the HMD device 102 vigorously, the sensor 206 would capture the vigorous shake movement data as well that is not required to be mirrored on to the virtual environment. Hence, the need of the filter unit 210 is to cut-off noises that are generated along with the movement data that the user 106 would not want to translate onto the virtual environment.

[0036] In one embodiment of the present invention, the filtered data is analysed by the processor 202 to determine whether the filtered data falls within a predefined threshold. The predefined threshold is determined considering various factors including, but not limited to, the type of movement performed by the user 106, the age group of the user 106, the time required by each user to perform a particular type of the movement. For example, if the user 106 is an adult within the age group of twenty-five to ifty-five years, and the adult is performing a walking movement, the predefined threshold is considered to be, but not limited to, between x and y, where x and y are absolute integers and / or rational numbers. The predefined threshold for a young adult between the age group of ten to twenty-four years would be greater than the predefined threshold for the adult. Further, the predefinedthreshold for an older adult above the age of fifty-six years old would be lower than the predefined threshold for the adult.

[0037] In another embodiment of the present invention, the predefined threshold is also determined based on a time taken by the user 106 for completing a cycle of the movement. For example, if the movement is walking then the predefined threshold would take into account the time required for the user 106 to complete one step. The time taken for completing a cycle of the movement would be different for different movement. For example, the time taken to complete one step of walking is more than the time taken to complete one step of running. For clarity, it is to be understood that the time taken for completing one step would mean the duration taken to complete placing of one leg forward for movements like running and walking and for the movements like jumping and hopping, it would be the duration taken to complete one cycle of hopping or jumping.

[0038] In an embodiment, the system 200 incorporates computational methods to determine the preferred predetermined threshold from a plurality of values calculated by evaluating various movements performed by the user 106 and the time take by the user 106 to perform the respective movement. The computational methods include at least one of but not limited to, data processing algorithms, machine learning models, and regression analysis.

[0039] In one embodiment of the present invention, if the processor 202 determines that the filtered data is within the predefined threshold, the processor 202 calculates a step count. The step count determined by the processor 202 is a step count the user takes in the real-world environment. Upon calculation of the step count in the real world, the processor 202 increase a virtual step in the virtual environment to reflect the user’s movement. The increase in the virtual step by processor 202 would facilitate a real-world mirroring of the user 106 movement in the virtual environment. Hence, achieving a more natural and intuitive navigation for the user in the virtual environment.

[0040] The UE 104 includes a display unit 204 that generates and presents a visual representation to the user 106 based on the user’s interactions and navigation within the VR ecosystem 100. In one embodiment, the display unit 204 generates andrenders the virtual world. The virtual world includes, but is not limited to, 3D graphics, textures, and animations, to create an immersive visual experience for the user 106. The visual representations are adapted to the user's current perspective and actions. The display unit 204 updates the visual display in real-time as the user navigates or interacts with the system 200.

[0041] FIG. 3 is a flow chart of a method 300 of step counting for virtual reality navigation, according to one or more embodiments of the present invention. For the purpose of description, the method 300 is described with the embodiments as illustrated in FIGs 1 and 2. Further, in order to avoid repetition and for the sake of brevity, the description for the FIGs 1 and 2 should be referred and should no where be construed as limiting the scope of the present disclosure.

[0042] At step 302, the method 300 includes the step of capturing, by a sensor 206, a movement data of a user 106 wearing a head mounted display (HMD) device 102.The sensor 206 includes an accelerometer sensor and / or a gyroscope sensor that capture the movement of the user 106 along the various axes including x-axis, y-axis and z-axis to get the translational and rotational value of the movement of the user 106

[0043] At step 304, the method 300 includes the step of filtering, through one or more processors 202, the movement data captured using the sensor 206 to attenuate a noise generated along with the movement data to get a filtered data. In one embodiment of the present invention, the processor 202 includes a filter unit 210, wherein the filter unit 210 is a low pass filter to smooth out noises that are generated from a movement data that is collected by the processor 202 from the sensor 206.

[0044] At step 306, the method 300 includes the step of analysing, by the one or more processors 206, the filtered data to determine if the filtered data is within a predefined threshold. In one embodiment of the present invention, the predefined threshold is calculated by considering various movements of the users including, but not limited to, walking, running, hopping, jumping, squatting and the like and also movements that the user 106 performs abruptly with the UE 104. Such abrupt motions need to be excluded while calculating a virtual step as unnecessary movement would cause user wearing the HMD device 102 to experience nauseaand giddiness as a VR environment gives an immersive experience. Hence, the predefined threshold is calculated keeping the above factor.

[0044] In another embodiment of the present invention, the predefined threshold may be fine-tuned for including users from different age groups including kids, adults and older adults. The pace in which a person moves including walking, running, etc. would change as the person ages. Also, the time frame between each step would also change. For example, a kid who is below the age of fifteen would be taking more steps within a particular time frame as compared to an adult who is between the age category of twenty-five to fifty-five. This means the time period between each step for a kid is less than that compared to the adult. Further, an older adult, people above the age of fifty-six would be taking fewer steps within a time frame as compared to kids and adults. This means that the time duration between two steps for the older adult will be more than that of the kid and the adult. Hence, the advantage of having a varying predefined threshold would accommodate users under various age categories for providing an immersive experience to any person wearing the HMD device 102.

[0045] At step 308, the method 300 includes the step of calculating, by the one or more processors 202, a step count if the filtered data is within the predefined threshold. At step 310, the method 300 includes the step of increasing, by the one or more processor, a virtual step based on the step count calculated to mirror a real-world movement of the user 106 in a virtual environment.

[0046] In an exemplary embodiment, the present invention is implemented in an android VR application. The VR application is a gaming application that the user 106 plays while wearing the HMD device 102 with the UE 104 placed inside the HMD device 102. In one aspect of the exemplary embodiment, the senor 206 inside the UE 104 captures the walking movement of the user 106. The walking movement data is transmitted to the filter unit 210 inside the processor 202. The filter unit 210 includes a low pass filter that would attenuate noises above a cut-off frequency. As the UE 104 is inserted inside the HMD device 102, when the user 106 walks, the UE 104 would move vertically inside the HMD device 102. Hence, for obtaining a filtered data, the y-axis component of the walking movement and the gravity actingduring the walking movement are considered. The filtered data is analysed to determine if the filtered data is within a predefined threshold.

[0047] In the exemplary embodiment of the present invention, the predefined threshold is set as, but not limited to, float threshold as 0.01 float and float maxthreshold as 0.1 float for the walking movement of the user 106 in the VR application. If the filtered data is within this range of value, then a step count is detected, by the processor 202, in a real-world. Upon detecting the step count, the processor 202 increases a virtual step in the android VR application. Thus, facilitating the user 106 to experience more natural and intuitive reflection of real-world walking in the virtual environment.

[0048] The present disclosure incorporates technical advancement that facilitates the user wearing the HMD device to mirror real-world movement onto the virtual environment. The advantage of the present invention is that the user gets a more natural and intuitive VR experience while wearing the HMD device. The user will also not be experiencing disorientation or sickness that users experience while using, currently available, VR application in HMD devices. Another advantage to the present invention is that the algorithm used to calculate the step count and increase the virtual step count could be fine-tuned for various VR applications and hardware configurations.

[0049] Various embodiments disclosed herein are to be taken in the illustrative and explanatory sense and should in no way be construed as limiting of the present invention. While aspects of the present invention have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods without departing from the scope of what is disclosed. Such embodiments should be understood to fall within the scope of the present invention as determined based upon the claims and any equivalents thereof.
