[0043] FIG. 5 is a processing flow chart illustrating an example embodiment of a method 500 as described herein. The method 500 of the example embodiment includes the following process operations: [0044] The control unit 100 determines the first movement and prompts the user via the multi-sensory output devices of the output unit 130 (process operation 502). [0045] The trackers and sensors of the input unit 110 capture the user's physical muscle movement and biomedical signals (process operation 504). [0046] The raw data signals received from the input unit 110 are provided to the control unit 100 (process operation 506). [0047] The control unit 100 analyzes the raw data signals and converts the data into indicators for scoring and performance tracking (process operation 508). [0048] Based on the indicators generated by the control unit 100, the control unit 100 causes the output unit 130 to generate user feedback via the multi-sensory output devices to simulate the effect or outcome of the user's physical movement (e.g., simulating breathed air coming in or out from the user's nose as shown in the virtual environment) (process operation 510). [0049] Based on the indicators generated by the control unit 100, the control unit 100 can determine the next user movement of a training program for which the user should be prompted (process operation 512). [0050] The control unit 100 causes the output unit 130 to generate a user prompt for the next user movement via the multi-sensory output devices (process operation 514). [0051] The user continues the physical movement cycles of the training program (repeat process starting at operation 502) until an ending condition occurs (e.g., user exit, time, certain score, etc.).

[0052] FIGS. 6 and 7 illustrate an example embodiment of a user wearable system 300 wherein sensor inputs are used to estimate and control a user's breathing status and performance. As described above, the headset 310 can include audio and visual output devices of the output unit 130. The headset 310 can also include the breathing sensor of the input unit 110. Various other sensors of the input unit 110, such as position/orientation sensors, heart rate sensors, breathing sensors, and chest size/movement sensors can be installed in a chest mounted device 320. Various other sensors of the input unit 110, such as position/orientation sensors, heart rate sensors, and oxygen sensors can be installed in a wrist-mounted device 330. Vibration or haptic devices of the output unit 130 can be installed in a hand-held device 340. Various other sensors of the input unit 110, such as position/orientation sensors and gesture detection sensors can also be installed in the hand-held device 340. Using the sensor inputs and user outputs of the user wearable system 300 as described above, the user's movements and condition can be monitored and directed. Moreover, the user outputs can be used to direct or control the user's movements to achieve a desired result. In this manner, the example embodiment can be used to monitor the user and to implement a training program to direct or prompt the user to move in a desired manner. For example, as described in more detail below, the user can be trained to breathe or move in a specific and controlled manner by use of the user wearable system 300. Using the various sensor devices of the input unit 110 as described above, the user wearable system 300 can interpret the sensor data from the user and generate various indicators or prompts that define particular user physical movements or conditions. These user movements or conditions can include: a user inhaling event, a user exhaling event, a breath holding event and duration, a user movement and average speed of movement, a level of user movement stability, user heart rate, user oxygen saturation level, stress level, and the like. These user movement and condition indicators can inform and direct the user's progress in accomplishing various portions or milestones of a training program. As a result, the embodiments disclosed herein can implement user breathing and muscle movement training by prompting the user to perform certain actions or movements and then collect the sensor data related to the user actions to determine the user's performance relative to the prompted action. The example embodiments disclosed herein can be used to implement a variety of training programs including: Breath monitoring with a breath sensor, Breath monitoring with posture tracking, Full body muscle training with gesture tracking, and Muscle training with head gaze tracking. Each of these training programs implemented with the user wearable system 300 of an example embodiment are described in more detail below.

Breath Tracking with a Breath Sensor

[0053] FIGS. 6 and 7 illustrate an example embodiment of a user wearable system 300 wherein sensor inputs are used to estimate and control a user's breathing process. If the user wearable system 300 of a particular embodiment is equipped with a breath sensor 312, the user wearable system 300 can use the sensor data directly from the breath sensor 312 to determine the user's current breathing status, such as: inhaling, exhaling, or holding breath. Secondly, the user wearable system 300 can use the sensor data directly from the breath sensor to determine the volume of air being inhaled or exhaled and the duration of each breathing cycle.

Breath Monitoring with Posture Tracking

[0054] Referring again to FIGS. 6 and 7, the user wearable system 300 of a particular embodiment may not be equipped with a breath sensor. In other implementations, the breath sensor may not be supplying accurate or reliable data. In this case, the user wearable system 300 can monitor and track the user's movements or posture to infer or estimate a breathing status and performance. For most people, core muscles always move in certain ways naturally while performing life supporting tasks, such as breathing. For example, during a deep inhaling cycle, most people naturally: (1) raise their head, (2) inflate their chest, (3) straighten their spine, and (4) open up their shoulders. These actions, which are measurable with the sensors of the user wearable system 300 of an example embodiment, are shown in FIG. 6. During a deep exhaling cycle, most people naturally: (1) lower their head, (2) deflate their chest, (3) bow their spine, and (4) relax their shoulders. These actions, which are measurable with the sensors of the user wearable system 300 of an example embodiment, are shown in FIG. 7. In particular, the user's head movement and/or gaze position can be measured relative to a plane 605 corresponding to a natural/neutral gazing position (e.g., a typical line-of-sight or level head position) when the user is in a static position. As shown in FIG. 6, the user's head position typically moves upward above the level plane 605 when the user is inhaling. Conversely, as shown in FIG. 7, the user's head position typically moves downward below the level plane 605 when the user is exhaling. Again, these user actions are measurable with the sensors of the user wearable system 300 of an example embodiment.

Full Body Muscle Training with Gesture Tracking

[0055] FIGS. 8 and 9 illustrate an example embodiment of a user wearable system 300 wherein sensor inputs are used to monitor and direct user hand movements for full-body muscle training. In an example embodiment, the user wearable system 300 can use sensors of the input unit 110 (e.g., IMU sensors 112 and/or sensors or output devices in the wrist-mounted device 330 or the hand-held device 340), which can be worn or held in the hands. The user can be prompted via displayed indicators or prompts through the headset 310 to perform specific muscle movements. The sensor data received from the hand-held device 340, for example, can enable the processing unit 120 to determine if the user muscle movements were performed as prompted. In this manner, the user wearable system 300 of an example embodiment can extend the tracking coverage of user movements to the entire user's body and enable full body muscle training. For example, an example embodiment can be configured to generate and display user prompts to cause the user to perform movements or postures that are beneficial to the body (e.g., movements or postures based on Yoga, Pilates, core body workouts, etc.). As shown in FIGS. 8 and 9, the example embodiment can also be configured to generate and display user prompts to cause the user to perform particular breathing exercises or movements to improve the user's breathing and/or movement performance. In this manner, the example embodiment can track muscle status with the movement of the user's hands. In other cases, the sensors of the input unit 110 of the user wearable system 300 (e.g., IMU sensors 112 and/or sensors or output devices in the wrist-mounted device 330 or the hand-held device 340) may be installed on or with both hands of the user. The example embodiment can be configured to generate and display user prompts to cause the user to perform particular movements with both hands (e.g., pointing with the hands). This enables the example embodiment to estimate the user's core muscle status and performance with hand position and orientation. Different target positions can be configured to improve the user's core muscle groups. Thus, the example embodiment can guide the user to move their head and hands to complete movements that are beneficial to body.

Muscle Training with Head Gaze Tracking

[0056] In a basic form according to an example embodiment, user muscle training can be monitored and directed by the user wearable system 300 wherein sensor inputs are used to monitor and direct user hand movements. Initially, the user wearable system 300 can estimate the user's core muscle status (e.g., breathing status) using the sensors of the input unit 110 of the user wearable system 300. In many cases, most of the sensors are installed in the headset 310. For implementations where most of the sensors are installed in the headset 310, a process for estimating the user's core muscle status can be based on the user's head orientation (e.g., how the user's head is oriented for gazing).

[0057] FIG. 10 illustrates an example embodiment of a method for training a user in optimal breathing performance by displaying two pointing targets to focus the user's gaze during inhaling and exhaling breathing cycles. In an implementation of this process using the user wearable system 300 as described herein, the user wearable system 300 can be configured to display two pointing targets via the multi-sensory display device of the output unit 130. The two pointing targets can be used to prompt the user to point (with head or hands) in various directions, one after another. When the user successfully gazes at the first target, the user wearable system 300 can be configured to highlight the next target and so forth. In various training programs, the user wearable system 300 can be configured to position the target above a level plane or a natural/neutral gazing position 605 during deep inhaling cycles and then position the target below the level plane or the natural/neutral gazing position 605 during deep exhaling cycles. By positioning the displayed targets in this manner, the user wearable system 300 can prompt and train the user to move their core muscle group to an ideal posture for optimal breathing performance. Further, the user wearable system 300 can be configured to demonstrate for the user the duration and consistency of their breathing cycles and thus show the user the effectiveness of their breathing performance.

[0058] FIG. 11 illustrates an example embodiment of a method for training a user in optimal breathing performance by displaying more than two pointing targets to focus the user's gaze during a square breathing exercise. In an implementation of this process using the user wearable system 300 as described herein, the user wearable system 300 can be configured to display more than two pointing targets via the multi-sensory display device of the output unit 130. The multiple pointing targets can be used to prompt the user to gaze at each of the targets, one after another, while breathing. When the user successfully gazes at the first target while inhaling, the user wearable system 300 can be configured to highlight the next target and so forth. At the second target, the user can be prompted to hold their breath. The user wearable system 300 can be configured to highlight the next target and prompt the user to exhale. The user wearable system 300 can then be configured to highlight the next target and prompt the user to hold their breath again. The process can be repeated to train the user in a square breathing technique. In various training programs, the user wearable system 300 can be configured to position the target above a level plane or a natural/neutral gazing position 605 during deep inhaling and hold cycles and then position the target below the level plane or the natural/neutral gazing position 605 during deep exhaling and hold cycles. By positioning the displayed targets in this manner, the user wearable system 300 can prompt and train the user to move their core muscle group to an ideal posture for optimal square breathing performance. Further, the user wearable system 300 can be configured to demonstrate for the user the duration and consistency of their breathing cycles and thus show the user the effectiveness of their breathing performance.

[0059] FIG. 12 illustrates an example embodiment of a method for training a user in optimal breathing performance by providing two height planes 1205 to focus the user's gaze at a desired height during inhale and exhale breathing cycles. One issue with breath training using a gazing target is that the user has less freedom to look around. To solve this, an example embodiment can be configured to display two height planes 1205 instead of prompting the user to gaze at certain point targets. In an implementation of this process using the user wearable system 300 as described herein, the user wearable system 300 can be configured to display the two height planes 1205 via the multi-sensory display device of the output unit 130. Typically, one of the two height planes 1205 is displayed above a neutral gaze point 605 (the upper height plane 1205) and the other one of the two height planes 1205 is displayed below the neutral gaze point 605 (the lower height plane 1205). The two height planes 1205 can be used to prompt the user to raise their head above the upper height plane 1205 during an inhale cycle. Similarly, the two height planes 1205 can be used to prompt the user to lower their head below the lower height plane 1205 during an exhale cycle. The user is allowed to move their head laterally as long as their head is above the upper height plane 1205 during an inhale cycle and below the lower height plane 1205 during an exhale cycle. The user wearable system 300 can be configured to highlight the appropriate height plane 1205 for each cycle to prompt the corresponding breathing cycles. By positioning the displayed height planes 1205 in this manner, the user wearable system 300 can prompt and train the user to move their core muscle group to an ideal posture for optimal breathing performance. Further, the user wearable system 300 can be configured to demonstrate for the user the duration and consistency of their breathing cycles and thus show the user the effectiveness of their breathing performance.

[0060] FIG. 13 illustrates an example embodiment of a method for training a user in optimal breathing performance by monitoring the height of a user's gaze over time to determine corresponding inhale and exhale breathing cycles. For example, if a current gaze point is higher than a gaze point at a previous point in time, the user wearable system 300 can determine that the user is likely performing an inhalation cycle. Similarly, if a current gaze point is lower than a gaze point at a previous point in time, the user wearable system 300 can determine that the user is likely performing an exhalation cycle. The length of time between a current and previous point in time is configurable. In this manner, the user wearable system 300 can monitor and track a user's breathing patterns. The user wearable system 300 can be configured to demonstrate for the user the duration and consistency of their breathing cycles and thus show the user the effectiveness of their breathing performance.

[0061] In another example embodiment, the user wearable system 300 can monitor and track a user's breathing patterns by enabling the user to press a button or activate an input device to mark the beginning and/or ending of each inhale and exhale breathing cycle. In this manner, the user can provide explicit input used to identify and track a user's breathing patterns.

[0062] In each of the training methods described herein, multi-sensory feedback is provided for the user to guide the user through each of the movements of the training program. The example embodiment can generate various displayed images, audio prompts, and other signals from the multi-sensory output devices of output unit 130 to create a positive feedback loop to guide the user's muscle movements. For example, the user wearable system 300 of an example embodiment can: [0063] Use the multi-sensory output devices of output unit 130 to present a visual simulated image and corresponding audio of air being inhaled and exhaled from a user's avatar in the virtual environment; [0064] Use the multi-sensory output device of output unit 130 to present the user's influence or effect on the virtual environment. For example, the simulated tree leaves in the virtual environment can be moved when the user inhales and exhales; [0065] Use the multi-sensory output device of output unit 130 to present positive energy or messages when the user performs the prompted movements correctly and vice versa; and [0066] Use the multi-sensory output device of output unit 130 to present stronger influences as the user progresses in performance (e.g., longer duration, more consistent movements, more accurate movements, etc.).

[0067] Referring now to FIG. 14, a processing flow diagram illustrates an example embodiment of a method 1100 as described herein. The method 1100 of an example embodiment includes: determining a prompted movement of a training program and using an output unit to prompt the user to perform the prompted movement (processing block 1110); receiving sensor data from an input unit, the sensor data corresponding to the user's physical movements and biomedical condition (processing block 1120); configuring the output unit to render a simulation of the user's physical movements in a virtual environment (processing block 1130); scoring the user's physical movements relative to the prompted movement (processing block 1140); and determining a next prompted movement of the training program and using the output unit to prompt the user to perform the next prompted movement until the training program is complete (processing block 1150).

[0068] FIG. 15 shows a diagrammatic representation of a machine in the example form of an electronic device, such as a mobile computing and/or communication system 700 within which a set of instructions when executed and/or processing logic when activated may cause the machine to perform any one or more of the methodologies described and/or claimed herein. In alternative embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a personal computer (PC), a laptop computer, a tablet computing system, a Personal Digital Assistant (PDA), a cellular telephone, a smartphone, a web appliance, a set-top box (STB), a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) or activating processing logic that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term machine can also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions or processing logic to perform any one or more of the methodologies described and/or claimed herein.

[0069] The example mobile computing and/or communication system 700 includes a data processor 702 (e.g., a System-on-a-Chip [SoC], general processing core, graphics core, and optionally other processing logic) and a memory 704, which can communicate with each other via a bus or other data transfer system 706. The mobile computing and/or communication system 700 may further include various input/output (I/O) devices and/or interfaces 710, such as a touchscreen display, an audio jack, and optionally a network interface 712. In an example embodiment, the network interface 712 can include one or more radio transceivers configured for compatibility with any one or more standard wireless and/or cellular protocols or access technologies (e.g., 2nd (2G), 2.5, 3rd (3G), 4th (4G) generation, and future generation radio access for cellular systems, Global System for Mobile communication (GSM), General Packet Radio Services (GPRS), Enhanced Data GSM Environment (EDGE), Wideband Code Division Multiple Access (WCDMA), LTE, CDMA2000, WLAN, Wireless Router (WR) mesh, and the like). Network interface 712 may also be configured for use with various other wired and/or wireless communication protocols, including TCP/IP, UDP, SIP, SMS, RTP, WAP, CDMA, TDMA, UMTS, UWB, WiFi, WiMax, Bluetooth, IEEE 802.11x, and the like. In essence, network interface 712 may include or support virtually any wired and/or wireless communication mechanisms by which information may travel between the mobile computing and/or communication system 700 and another computing or communication system via network 714.

[0070] The memory 704 can represent a machine-readable medium on which is stored one or more sets of instructions, software, firmware, or other processing logic (e.g., logic 708) embodying any one or more of the methodologies or functions described and/or claimed herein. The logic 708, or a portion thereof, may also reside, completely or at least partially within the processor 702 during execution thereof by the mobile computing and/or communication system 700. As such, the memory 704 and the processor 702 may also constitute machine-readable media. The logic 708, or a portion thereof, may also be configured as processing logic or logic, at least a portion of which is partially implemented in hardware. The logic 708, or a portion thereof, may further be transmitted or received over a network 714 via the network interface 712. While the machine-readable medium of an example embodiment can be a single medium, the term machine-readable medium should be taken to include a single non-transitory medium or multiple non-transitory media (e.g., a centralized or distributed database, and/or associated caches and computing systems) that store the one or more sets of instructions. The term machine-readable medium can also be taken to include any non-transitory medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the various embodiments, or that is capable of storing, encoding or carrying data structures utilized by or associated with such a set of instructions. The term machine-readable medium can accordingly be taken to include, but not be limited to, solid-state memories, optical media, and magnetic media.

[0071] The methods disclosed herein may be implemented as a computer program product, i.e., a computer program tangibly embodied in a non-transitory information carrier, e.g., in a machine-readable storage device, or a tangible non-transitory computer-readable medium, for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers. A computer program may be written in any form of programming language, including compiled or interpreted languages, and it may be deployed in any form, including as a standalone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program may be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network. A portion or all of the systems disclosed herein may also be implemented by an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex programmable logic device (CPLD), a printed circuit board (PCB), a digital signal processor (DSP), a combination of programmable logic components and programmable interconnects, a single central processing unit (CPU) chip, a CPU chip combined on a motherboard, a general purpose computer, or any other combination of devices or modules capable of processing optical image data and generating actions in a virtual world based on the methods disclosed herein.
