Detailed Description

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

"Wearable article" as referred to throughout the present disclosure may refer to any form of article which may be worn by a user such as a smart watch, necklace, bracelet, or glasses. The wearable article may be a textile article. The wearable article may be a garment. The garment may refer to an item of clothing or apparel. The garment may be a top. The top may be a shirt, t-shirt, blouse, sweater, jacket/coat, or vest. The garment may be a dress, brassiere, shorts, pants, arm or leg sleeve, vest, jacket/coat, glove, armband, underwear, headband, hat/cap, collar, wristband, stocking, sock, or shoe, athletic clothing, personal protecting equipment, swimwear, wetsuit or drysuit The garment may be a tight-fitting garment. Beneficially, a tight-fitting garment helps ensure that the sensor devices of the garment are held in contact with or in the proximity of a skin surface of the user. The garment may be a compression garment. The garment may be an athletic garment such as an elastomeric athletic garment.

The wearable article may be constructed from a woven or a non-woven material. The wearable article may be constructed from natural fibres, synthetic fibres, or a natural fibre blended with one or more other materials which can be natural or synthetic. The yam may be cotton. The cotton may be blended with polyester and/or viscose and/or polyamide according to the application. Silk may also be used as the natural fibre. Cellulose, wool, hemp and jute are also natural fibres that may be used in the wearable article. Polyester, polycotton, nylon and viscose are synthetic fibres that may be used in the wearable article.

The following description refers to examples of the present disclosure where the wearable article is a garment. It will be appreciated that the present disclosure is not limited to garments and other forms of wearable article are within the scope of the present disclosure as outlined above.

Referring to Figure 1, there is shown an example system 1 according to aspects of the present disclosure. The system 1 comprises wearable assembly 10 and apparatus 300 in the form of a mobile device 300. The wearable assembly 10 comprises an electronics module 100, and a garment 200.

The electronics module 100 is arranged to wirelessly communicate data to the mobile device 300. Various protocols enable wireless communication between the electronics module 100 and the mobile device 300. Example communication protocols include Bluetooth ®, Bluetooth Low

Energy, and near-field communication (NFC).

The garment 200 has sensing components provided on an inside surface which are held near a skin surface of a user wearing the wearable assembly 10. This enables the sensing components to measure activity data such as biosignals for the user wearing the garment 200.

The sensing components may be arranged to sense one or more signals external to the user. The sensing components may comprise any or a combination of a temperature sensor, a camera, a location tracking module such as a GPS module, and a chemical sensor.

The sensing components may be arranged to measure one or more biosignals of a user wearing the wearable article. Here, "biosignal" may refer to any signal in a living being that can be measured and monitored. The term "biosignal" is not limited to electrical signals and can refer to other forms of non-electrical biosignals. The sensing components may be used for measuring one or a combination of bioelectrical, bioimpedance, biochemical, biomechanical, bioacoustics, biooptical or biothermal signals of the user. The bioelectrical measurements include electrocardiograms (ECG), electrogastrograms (EGG), electroencephalograms (EEG), and electromyography (EMG). The bioimpedance measurements include plethysmography (e.g., for respiration), body composition (e.g., hydration, fat, etc.), and electroimpedance tomography (Eli). The biomagnetic measurements include magnetoneurograms (MNG), magnetoencephalography (MEG), magnetogastrogram (MGG), magnetocardiogram (MCG). The biochemical measurements include glucose/lactose measurements which may be performed using chemical analysis of the user's sweat. The biomechanical measurements include blood pressure. The bioacoustics measurements include phonocardiograms (PCG). The biooptical measurements include orthopantomogram (OPG). The biothermal measurements include skin temperature and core body temperature measurements. The sensing components may comprise a radar unit. The wearable article may sense a combination of external signals and biosignals of the user.

The activity data may comprise any or a combination of the different example measurements described above.

The garment 200 has an electronics module holder 201 in the form of a pocket 201. The pocket 201 is sized to receive the electronics module 100. When disposed in the pocket 201, the electronics module 100 is arranged to integrate with the sensing components of garment 200 and receive activity data from the sensing components. The electronics module 100 is therefore removable from the garment 200.

The present disclosure is not limited to electronics module holders 201 in the form pockets 201.

Instead, other mechanism for releasably mechanically coupling the electronics module 100 to the garment 200 may be provided. The mechanical coupling of the electronic module 100 to the garment 200 may be provided by a mechanical interface such as a clip, a plug and socket arrangement, etc. The mechanical coupling or mechanical interface may be configured to maintain the electronic module 100 in a particular orientation with respect to the garment 200 when the electronic module 100 is coupled to the garment 200. This may be beneficial in ensuring that the electronic module 100 is securely held in place with respect to the garment 200 and/or that any electronic coupling of the electronic module 100 and the garment 200 (or a component of the garment 200) can be optimized. The mechanical coupling may be maintained using friction or using a positively engaging mechanism, for example.

Beneficially, the removable electronic module 100 may contain all the components required for data transmission and processing such that the garment 200 only comprises the sensing components and communication pathways. In this way, manufacture of the garment 200 may be simplified. In addition, it may be easier to clean a garment 200 which has fewer electronic components attached thereto or incorporated therein. Furthermore, the removable electronic module 100 may be easier to maintain and/or troubleshoot than embedded electronics. The electronic module 100 may comprise flexible electronics such as a flexible printed circuit (FPC). The electronic module 100 may be configured to be electrically coupled to the garment 200.

The electronics module 100 transmits the activity data to an external apparatus such as mobile device 300.

In environments such as team sports or workplace settings, there may be a number of different users wearing different wearable assemblies 10 at the same time. Each of the wearable assemblies 10 will have a different electronics module 100 transmitting data to the same external apparatus such as mobile device 300. The data transmitted by the electronics module 100 will be associated with an electronics module identifierthat uniquely identifies the electronics module 100. The electronics module identifier may be, for example, a communication address for the electronics module 100.

Generally, it is desirable that there is no fixed association between electronics module 100 and a garment. This provides greater flexibility in a sports or workplace setting. A pool of electronics modules 100 may be maintained by a central provider. This enables one electronics module 100 to be, over time, used with different garments 200 worn by different users. Because there is no fixed association between a user wearing a garment 200 and a particular electronics module 100 incorporated into the pocket 201 of the garment 200, it will be challenging and may not be possible (depending on the number of electronics modules, for example) for the mobile device 300 to confidently determine which garment, and thus which user, the received activity data relates to. This limits the utility of the received activity data as it is not possible to provide insights and analysis for a particular user.

To overcome this problem, the garment 200 of the wearable assembly 10 includes a wearable article identifier 203. The wearable article identifier 203 is a machine-readable code that is readable from the outside surface of the garment 200. The wearable article identifier identifies the garment, and thus the user. The electronics module identifier is different to the wearable article identifier and identifies the electronics module which has no fixed association with the garment.

In an example operation, the mobile device 300 communicates with the electronics module 100 to obtain the electronics module identifier for the electronics module 100. The mobile device 300 also reads the machine-readable code 203 of the garment 200 to obtain the wearable article identifier for the garment 200. The mobile device 300 then associates the electronics module identifier with the wearable article identifier. In this way, when activity data is received from the electronics module 100, the mobile device 300 is able to determine that the activity data relates to a particular garment 200 and thus a particular user.

In a preferred implementation, the association between the electronics module 100 and the garment 200 is formed once the electronics module 100 is positioned in the pocket 201 and the garment 200 is worn by a user. The mobile device 300 may be brought into proximity with the pocket 201 to obtain the electronics module identifier. A camera of the mobile device 300 may then capture image data including the machine-readable code 203. This is then used by the mobile device 300 to form an association between the electronics module 100 and the garment 200. For example, the mobile device 300 may store the electronics module identifier and the wearable article identifier together in a database 301. In other examples, the mobile device 300 may transmit the electronics module identifier and wearable article identifier to an external apparatus which maintains the database 301.

The wearable article identifier may be, for example, derived from a proprietary garment manufacturer identifier. The wearable article identifier may be an identifier for a user that wears the garment. That is, the wearable article identifier may be a unique identifier for a particular user. The wearable article identifier may comprise a combination of a garment manufacturer identifier and a user identifier. The wearable article identifier may comprise a username or number such as a jersey number used in athletics.

The present disclosure means that limited manual input is required to form an association between an electronics module identifier and a wearable article identifier. A user is not required to manually input or select electronics module identifiers and wearable article identifiers via an interface of the mobile device 300 and is not required to form the association manually. Instead, the user may simply tap the mobile device 300 against the wearable assembly 10 to read the electronics module identifier and the use the mobile device 300 to read the machine-readable code 203. The user may be prompted to perform these steps by an application running on the mobile device 300. Once the electronics module identifier and wearable article identifier are obtained, the mobile device 300 may automatically form the association between the electronics module identifier and the wearable article identifier without further user input.

The present disclosure is not limited to electronics modules 100 that communicate with mobile devices 300 and instead may communicate with any electronic device capable of communicating directly with the electronics module 100 or indirectly via an external apparatus over a wired or wireless communication network. The electronic device may be a wireless device or a wired device. The wireless/wired device may be a mobile phone, tablet computer, gaming system, MP3 player, point-of-sale device, or wearable device such as a smart watch. A wireless device is intended to encompass any compatible mobile technology computing device that connects to a wireless communication network, such as mobile phones, mobile equipment, mobile stations, user equipment, cellular phones, smartphones, handsets or the like, wireless dongles or other mobile computing devices. The wireless communication network is intended to encompass any type of wireless such as mobile/cellular networks used to provide mobile phone services.

Referring to Figure 2, there is shown a schematic diagram for the electronics module 100 of Figure 1.

The electronics module 100 comprises an interface 101, a controller 103, a power source 105, a communicator 107.

The interface 101 is arranged to communicatively couple with sensing components of the garment 200 (Figure 1) to receive signals from the sensing components. The controller 103 is communicatively coupled to the interface 101 and is arranged to receive the signals from the interface 101 The interface 101 may form a conductive coupling or a wireless (e.g. inductive) communication coupling with the electronics components of the wearable article The power source 105 is coupled to the controller 103 and is arranged to supply power to the controller 103. The power source 105 may comprise a plurality of power sources. The power source 105 may be a battery. The battery may be a rechargeable battery. The battery may be a rechargeable battery adapted to be charged wirelessly such as by inductive charging. The power source 105 may comprise an energy harvesting device. The energy harvesting device may be configured to generate electric power signals in response to kinetic events such as kinetic events performed by a user of the garment. The kinetic event could include walking, running, exercising or respiration of the user. The energy harvesting material may comprise a piezoelectric material which generates electricity in response to mechanical deformation of the converter. The energy harvesting device may harvest energy from body heat of a user of the garment. The energy harvesting device may be a thermoelectric energy harvesting device. The power source may be a super capacitor, or an energy cell.

The communicator 107 is arranged to communicatively couple with the mobile device 300 over a wireless communication protocol. The wireless communication protocol may be a near field communication (NFC) protocol but is not limited to any particular communication protocol. The communicator 107 may transmit activity data obtained from the sensing component to the mobile device 300. The activity data may be a processed version of the signals obtained from the sensing component/ In an example operation, the mobile device 300 is brought into proximity with the electronics module 100. In response to this, the electronics module 100 is configured to energize the communicator 107 to transmit the electronics module identifier to the mobile device 300 over a wireless communication protocol. Beneficially, this means that the act of the mobile device 300 approaching the electronics module 100 triggers the communicator 107 to transmit the electronics module identifier to the mobile device 300. This provides a simple and intuitive mechanism for transmitting the electronics module identifier to the mobile device 300 which does not require the user manually input the identifier via a user interface of the mobile device 300 for example. The electronics module 100 may listen out for a break in the near field of the communicator 107 antenna caused by the mobile device 300 approaching the communicator 107. This detection of a disruption in the near field will be used to trigger the communicator 107 to transmit the electronics module identifier to the mobile device 300.

The electronics module identifier is a unique identifier for the electronics module 100 that enables the mobile device 300 to uniquely identify the electronics module 100. The electronics module identifier may be an address for the electronics module 100 such as a MAC address or Bluetooth ® address or may be a component of an address for the electronics module identifier.

In some examples, the communicator 107 is a component of a passive tag such as a passive Radio Frequency Identification (RFID) tag or Near Field Communication (NFC) tag. These tags comprise an antenna as well as a memory which stores the information, and a radio chip. The mobile device 300 is powered to induce a magnetic field in an antenna of the mobile device 300. When the mobile device 300 is placed in the magnetic field of the antenna of the communicator 107, the mobile device 300 induces current in the antenna of the communicator 107. This induced current is used to retrieve the electronics module identifier from the memory of the tag and transmit the same back to the mobile device 300.

In other examples, the communicator 107 is not a component of a tag. In these examples, the electronics module 100 may detect a mobile device 300 being brought into proximity with electronics module 100 based on factors such as through a sensor of the electronics module 100 or a current being induced in an antenna of the communicator 107. Once the electronics module 100 determines that the mobile device 300 is in proximity with the electronics module 100, the controller 103 reads the electronics module identifier from the memory of the controller 103 or an external memory and energizes the communicator 107 to transmit the electronics module identifier Beneficially, this approach provides greater customisability and allows for different information and dynamically changing information to be transmitted by the communicator 107. That is, the information transmitted by the first antenna 107 can be dynamically changed, e.g. to dynamically change the electronics module identifier. This is because the controller 103 is able to update the content stored in the memory which is not possible in a passive NFC or RFID tag. This is particularly beneficial if it is desirable to update or modify the electronics module identifier that is transmitted to the mobile device 300.

The communicator 107 is not limited to transmitting over the wireless communication protocols described above. The communicator 107 may be a mobile/cellular communicator operable to communicate the data wirelessly via one or more base stations. The communicator 107 may provide wireless communication capabilities for the electronics module 100 and enable the electronics module 100 to communicate via one or more wireless communication protocols such as used for communication over: a wireless wide area network (VAN), a wireless metroarea network (VVMAN), a wireless local area network (VVLAN), a wireless personal area network (WPAN), Bluetooth Low Energy, Bluetooth 0 Mesh, Bluetooth 5, Thread, Zigbee, IEEE 802.15.4, ANT, ANT+, a near field communication (NFC), a Global Navigation Satellite System (GNSS), a cellular communication network, or any other electromagnetic RE communication protocol. The cellular communication network may be a fourth generation (4G) LTE, LTE Advanced (LTE-A), LTE Cat-M1, LTE Cat-M2, NB-IoT, fifth generation (5G), sixth generation (6G), and/or any other present or future developed cellular wireless network. A plurality of communicators may be provided for communicating over a combination of different communication protocols.

The electronics module 100 may comprise a Universal Integrated Circuit Card (UICC) that enables the wearable article to access services provided by a mobile network operator (MNO) or virtual mobile network operator (VMNO). The UICC may include at least a read-only memory (ROM) configured to store an MNO/VMNO profile that the electronics module 100 can utilize to register and interact with an MNONMNO. The UICC may be in the form of a Subscriber Identity Module (SIM) card. The electronics module 100 may have a receiving section arranged to receive the SIM card. In other examples, the UICC is embedded directly into the controller 103. That is, the UICC may be an electronic/embedded UICC (eUICC). A eUICC is beneficial as it removes the need to store a number of MNO profiles, i.e. electronic Subscriber Identity Modules (eSIMs). Moreover, eSIMs can be remotely provisioned to electronics module 100. The electronics module 100 may comprise a secure element that represents an embedded Universal Integrated Circuit Card (eUICC).

Referring to Figure 3, there is shown a schematic diagram of another example electronics module 100 according to aspects of the present disclosure. The electronics module 100 comprises an interface 101, a controller 103, a power source 105, a communicator 107, and an input unit 109. The interface 101, controller 103, power source 105, and communicator 107 are the same as described in reference to Figure 2.

The input unit 109 is arranged to detect the mobile device 300 being brought into proximity with the electronics module 100. The input unit 109 may comprise a button such as a mechanical push button which is actuated when a mobile device 300 is brought into proximity with the push button. The input unit 109 preferably comprises a sensor 109 such as a proximity sensor or motion sensor.

In the example of Figure 3, the sensor 109 is a motion sensor that is arranged to detect a displacement of the electronics module 100 caused by the mobile device being brought into proximity with the electronics module 100. These displacements of the electronics module 100 may be caused by the mobile device 300 being tapped against the electronics module 100. Physical contact between the mobile device 300 and the electronics module 100 is not required as the electronics module 100 may be in a holder such as a pocket of a wearable article. This means that there may be a fabric (or other material) barrier between the electronics module 100 and the mobile device 300. In any event, the electronics module 100 being brought into contact with the fabric of the pocket will cause an impulse to be applied to the electronics module 100 which will be sensed by the sensor 109.

The sensor 109 may comprise an inertial measurement unit. The inertial measurement unit may comprise an accelerometer and optionally one or both of a gyroscope and a magnetometer. A gyroscope/magnetometer is not required in all examples, and instead only an accelerometer may be provided, or a gyroscope/magnetometer may be present but put into a low power state. A processor of the sensor 109 may perform processing tasks to classify different types of detected motion. The processor of the sensor 109 may perform machine-learning functions so as to perform this classification. Performing the processing operations on the sensor 109 rather than the controller 103 is beneficial as it reduces power consumption and leaves the controller 103 free to perform other tasks. In addition, it allows for motion events to be detected even when the controller 103 is operating in a low power mode. The sensor 109 communicates with the controller 103 over a serial protocol such as the Serial Peripheral Interface (SPI), Inter-Integrated Circuit (12C), Controller Area Network (CAN), and Recommended Standard 232 (RS-232). Other serial protocols are within the scope of the present disclosure. The sensor 109 is also able to send interrupt signals to the controller 103 when required so as to transition the controller 103 from a low power mode to a normal power mode when a motion event is detected. The interrupt signals may be transmitted via one or more dedicated interrupt pins. Activity data recorded by the inertial measurement unit may be transmitted to the mobile device 300.

In an example operation, the electronics module 100 is operating in a low power mode. In this low power mode, the majority of the components of the electronics module 100 are not operating so as to save power. For example, the communicator 107 is not energized to transmit data and the controller 103 is not activated to process signal data received via the interface 101. The sensor 109 is supplied with power during the low power mode and is arranged to sense motion data. The sensor 109 may not have full functionality in the low power mode and may only have the necessary processing power to classify motion events into simple categories such as whether a tap has occurred. More computationally expensive processing operations may be disabled during the low power mode. In response to the sensor 109 detecting a tap event, the sensor 109 sends an interrupt to the controller 103. As a result, the controller 103 wakes up from the low power mode and polls the sensor 109 to determine the reason for the interrupt being sent. The sensor 109 responds with a signal indicating that a tap has been detected. The controller 103 then begins the process for controlling the communicator 107 to transmit the electronics module identifier. In particular, the controller 103 reads the electronics module identifier from a memory of the electronics module 100 and energizes the communicator 107 to transmit the information such as the unique identifier.

Referring to Figure 4, there is shown another example system 1 according to aspects of the present disclosure.

The system 1 comprises a plurality (three in this example) of wearable assemblies 10a, 10b, 10c each worn by a different user and a base station 300 which in this example is a mobile device 300. The wearable assemblies 10a, 10b, 10c include electronics modules provided in an inner garment layer which is not visible in Figure 4. The wearable assemblies 10a, 10b, 10c further comprise an outer garment 200a, 200b, 200c which each comprise a (potentially unique) wearable article identifier in the form of a machine-readable code 203a, 203b, 203c. These outer garments 200a, 200b, 200c may not comprise any sensing components. The sensing functionality may be provided by the electronics modules alone or by the electronics modules interfacing with sensing components such as electrodes provided in the inner garment layer.

During an initial registration stage, for each user, the mobile device 300 associates the outer garment 200a, 200b, 200c worn by the user with the electronics module provided in the inner garment layer worn by the same user. To do this, the mobile device 300 is brought into proximity with the electronics module of the wearable assembly 10a, 10b, 10c to obtain the electronics module identifier. This may be performed by tapping the mobile device 300 against the outer garment 200a, 200b, 200c in the vicinity of the electronics module. The mobile device 300 then reads the machine-readable code of the outer garment 200a, 200b, 200c to obtain the wearable article identifier. In particular, the camera of the mobile device 300 captures an image of the outer garment 200a, 200b, 200c and reads the machine-readable code from the captured image. The first mobile device 300 then forms the association between the electronics module identifier and the wearable article identifier for the wearable assembly 10a, 10b, 10c and stores this association in database 301. The present disclosure thus provides a convenient and user-friendly method by which associations are formed between individuals wearing the wearable assemblies 10a, 10b, 10c and the electronics modules of the wearable assemblies 10a, 10b, 10c.

Subsequently, the first mobile device 300 is in communication with each of the electronics modules and is able to receive activity data therefrom. Because the association between electronics module identifier and the wearable article identifier has been formed, the mobile device 300 is able to determine which garment, and thus which user, the received activity data relates to. In particular, the mobile device 300 can obtain the electronics module identifier from incoming activity data and compare this electronics module identifier to the database 301 to determine the wearable article identifier that the electronics module identifier is associated with.

In some situations, it is desirable for an operator of the mobile device 300 to quickly view activity data for a particular user 10a, 10b, 10c. For example, the operator of the mobile device 300 may be a coach of a sports team who desires to view activity data for a particular athlete. This may help the coach make an assessment of whether the athlete is fatigued and/or at risk of injury. The display of the mobile device 300 may display activity data for a number of users at the same time, but this may limit the amount and type of data that is displayed and it may be difficult for the operator to quickly determine a status of the athlete. The operator could manually enter athlete identification information such as a name or player number into an application running on the mobile device 300 to obtain the activity data, but this is user intensive and prone to error.

Beneficially, aspects of the present disclosure provide an improved and more user intuitive mechanism for obtaining activity data associated with a specific garment 200a, 200b, 200c and thus a specific user 10a, 10b, 10c. In particular, the operator of the mobile device 300 is able to use a reader of the mobile device 300 to read the machine-readable code of the garment 200a, 200b, 200c worn by the user that the operator desires to view data for. The mobile device 300 obtains the wearable article identifier from the machine-readable code and then inspects the database 301 to identify the electronics module identifier associated with the wearable article identifier. The mobile device 300 can then fetch activity data for the identified electronics module and display the activity data, such as by displaying a representation thereof, on the display 303 of the mobile device 300.

Referring to Figure 5, there is shown an example interface 400 displayed on the display 303 of the mobile device 300. The interface includes a live view image 401 that is captured by a camera of the mobile device 300. The live view image 401 includes user 3 wearing the wearable assembly 10. The user 3 is the user that the operator of the mobile device 300 desires to view activity data for, and the operator has positioned the reader of the mobile device 300 such that the reader captures an image of the wearable assembly 10. This enables the mobile device 300 to obtain the machine-readable code 203 from the image and use this to obtain the wearable article identifier.

The interface 400 further includes a text box 5 that overlays the live view image and includes information for the user 3. The information includes activity data obtained from an electronics module worn by the user 3. In this example, the activity data comprises cardiac activity data and the text box display information related to the cardiac performance of the user 3 including their heart rate, the training zone they are operating in, and whether they are at risk of injury. This information enables the operator to make a rapid assessment of the performance of the user 3.

Referring to Figure 6, there is shown another example interface 400 displayed on the display 301 of the mobile device 300. The user interface displays a live view image 401 that is captured by the camera of the mobile device 300. The live view image 401 is a live video feed that currently contains the user 3 that the operator of the mobile device 300 desires to view activity data for.

The garment 200 has a machine-readable code 203 that comprises the wearable article identifier. The machine-readable code 203 in this example is in the form of a fiducial marker 203 located on an outside surface of the garment 200. Beneficially, the fiducial marker 203 not only includes the wearable article identifier but also enables motion tracking to be performed.

In this example, the mobile device 300 uses the received activity data to augment the live view image 401 displayed on the interface 400. In this example, the received activity data comprises ECG data for the user. The application running on the mobile device 300 uses the ECG data to generate an augmented reality object 403. The augmented reality object 403 is displayed at a position determined based on the location of the fiducial marker 203. The effect of this is that the augmented reality object 403 appears on the display to overlay the cardiac region of the user of the garment 200. The augmented reality object 403 provides a representation of the ECG data.

The augmented reality object 403 comprises a 3D model of the heart 405 that is animated to beat at a rate corresponding to the heart rate of the user. The 3D model of the heart 405 changes colour based on the heart rate of the user. The 3D model of the heart 405 is green when the heart rate is at a low value (e.g. less than 100 beats per minute), yellow when the heart rate is at a medium value (e.g. between 100 and 145 beats per minute) and red when the heart rate is at a high value (e.g. greater than 145 beats per minute). Of course, other colours may be used. The 3D model of the heart may additionally or separately change size, shape or texture depending on the heart rate.

The augmented reality object 403 comprises a numerical display of the heart rate 407. The augmented reality object 403 comprises a display of ECG data 409. The display of the heart rate 407 and the ECG data 409 may also change colour, size, shape or texture depending on the heart rate. Conveniently, the present invention conveys cardiac information to the observer in a way that is easy and intuitive to understand as the augmented reality object 403 is positioned to overlay the cardiac region of the user.

Referring to Figure 7, there is shown an example use case of the system 1 in accordance with the present disclosure. The system 1 comprises a number of wearable assemblies 10 worn by athletes participating in a sports event on a pitch 500. This particular example shows a five-a-side football tournament.

The system 1 further comprises an apparatus 300 such as a mobile device 300 and a base station 400. The base station 400 is in wireless communication with the wearable assemblies 10 and is able to receive activity data from the wearable assemblies 10. The mobile device 300 is operated by a coach or medic on the sidelines of the pitch 500.

Each of the wearable assemblies 10 comprises a garment with a machine-readable code comprising a wearable article identifier and an electronics module that transmits activity data to the apparatus 300. During an initial registration process, for each of the wearable assemblies 10, the electronics module identifier is associated with the wearable article identifier. To do this, the apparatus 300 reads the electronics module identifier and the wearable article identifier for a particular user and associates the electronics module identifierto the wearable article identifier.

In some examples, the base station 400 receives the activity data from the plurality of electronics modules and, for one or a plurality of the electronics modules, transmits the activity data (which may be a processed version of the originally received activity data) and the electronics module identifier to the apparatus 300.

The apparatus 300 uses the received electronics module identifier to identify the wearable article identifier associated with the electronics module identifier. In this way, the apparatus 300 identifies the user wearing the electronics module. The apparatus 300 may then display the activity data along with identifying information for the user. The identifying information may include a username, picture or other identifying information. This approach enables the apparatus 300 to determine which garment and thus which athlete incoming activity data relates to.

In some examples, the base station 400 receives the activity data from the plurality of electronics modules. The operator of the apparatus 300 may desire to view activity data for one or more of the players on the pitch 500. To do this, the operator uses the apparatus 300 to read wearable article identifier for the player or players. The apparatus 300 uses the wearable article identifier to identify the electronics module identifier associated with the wearable article identifier. The apparatus 300 transmits the electronics module identifier to the base station 400 as part of a request for activity data. The base station 400 transmits the activity data (which may be a processed version of the originally received activity data) for the electronics module identified by the electronics module identifier to the apparatus 300. The apparatus 300 may then display the activity data along with identifying information for the user. The identifying information may include a username, picture or other identifying information. This approach enables the apparatus 300 to determine which garment and thus which athlete incoming activity data relates to.

Referring to Figure 8, there is shown an example use case of the system 1 in accordance with the present disclosure. The system 1 comprises a number of wearable assemblies 10 worn by athletes participating in a sports event on a pitch 500. This particular example shows a five-a-side football tournament.

The system 1 further comprises an apparatus 300 which is in wireless communication with the wearable assemblies 10 and is able to receive activity data from the wearable assemblies 10. The data processing apparatus further comprises a plurality of cameras 305 distributed around the pitch 500 which capture live view image data and provide the same to the apparatus 300.

Each of the wearable assemblies 10 comprises a garment with a machine-readable code comprising a wearable article identifier and an electronics module that transmits activity data to the apparatus 300. During an initial registration process, for each of the wearable assemblies 10, the electronics module identifier is associated with the wearable article identifier. In this way, the apparatus 300 is able to determine which garment and thus which athlete incoming activity data relates to. This association may be performed by an external apparatus such as a mobile device.

The apparatus 300 uses the live view image data received from the cameras 305 to generate a video feed for broadcast or distribution using other means. It would be desirable to supplement the generated video feed with the received activity data such as by overlaying representations of the activity data onto the video feed in a manner similar to the examples shown in Figures 5 and 6.

To achieve this effect, a human producer could inspect the incoming video feed to determine the athletes contained within the live view image and then fetch activity data for these athletes.

However, this approach is labour intensive and prone to error.

Beneficially, in accordance with the present disclosure, the apparatus 300 can identify machine readable code(s) for garment(s) present in the live view image and use this machine-readable code to obtain activity data for the athletes wearing the identified garment(s). In this way, an automatic approach for supplementing image data with activity data is provided which does not require human input.

Referring to Figure 9, there is shown an example apparatus 300 according to aspects of the present disclosure. The apparatus 300 in the example of Figure 9 comprises a database 301, display 303, reader 305, controller 307 and communicator 309. It will be appreciated that the apparatus 300 is not required to include all of these components and may comprise additional or separate components.

Further, the reader 305 arranged to read a machine-readable code comprising a wearable article identifier from an outside surface of the garment.

The controller 307 is arranged to associate the electronics module identifier with the wearable article identifier. This may involve the controller 307 storing the electronics module identifier and wearable article identifier on a local database 301. Additionally, or separately, the controller 307 may control the communicator 309 to transmit the associated electronics module identifier and the wearable article identifier to an external apparatus such as a base station.

In some example implementations, the apparatus 300 performs operations to access activity data from an electronics module of a wearable assembly according to aspects of the present disclosure In these examples, the reader 305 is arranged to read a machine-readable code comprising a wearable article identifier from an outside surface of the garment of the wearable assembly.

Further, the controller 307 is operable to use the wearable article identifier to identify an electronics module identifier associated with the wearable article identifier. The controller 307 then uses the electronics module identifier to obtain activity data from the electronics module. The activity data is associated with a user wearing the garment. This may involve the controller 307 accessing the local database 301 to determine the electronics module identifier associated with the wearable article identifier, and then accessing locally stored activity data for the identified electronics module. Alternatively, the apparatus 300 may communicate with a server to obtain the activity data.
