Description

[Technical field]

[0001] The present invention relates to a method and a wearable device for comparing personal biometric data of two users. [Background technology]

[0002] Semiconductor nanotechnology and optical technology have greatly contributed to people's lifestyles, especially by facilitating hardware miniaturization. Its application in genetic engineering and genotyping industries has enabled so-called "lab-on-a-chip" systems. Depending on the biological question / gene of interest, primer(s) / probe(s)--more commonly called "biomarkers"--are designed accordingly. Biomarkers can be oligonucleotides, such as DNA molecules, that target specific gene(s) / mutation(s). Alternatively, biomarkers can be, for example, antibiotics or antigens. By applying / selecting different types of biomarkers on such systems, customers can test their biological specimens, DNA, RNA, proteins, etc. (e.g., extracted locally or remotely by a third party from saliva, blood, urine, tissue, stool, hair, etc.) for specific traits, possibly as required by a particular lifestyle concern or interest.

[0003] Such "personalized" genetic or bioinformation allows medical decisions to be made more effectively, for example, by selecting treatments or drug dosages that are more likely to be effective for a particular patient. Identifying individual differences at the molecular level also allows lifestyle and dietary advice to be tailored according to the needs of an individual or a class of individuals. For example, personal care products such as cosmetics and nutraceuticals may be selected based on how effective these products are for individuals who have particular single nucleotide polymorphisms in their DNA. Many private companies have sprung up to serve the growing consumer genetics market, and new genetic traits are described daily, generating an ever-expanding catalog of biomarkers that have the potential to add insight into the health, wellness, and in the case of genetic variation, phenotype, of a great many people.

[0004] This kind of "liberation" of personal genetic data as described above could benefit individuals in many different ways, but the abstract nature of the data may make it difficult for individuals to recognize its value. For example, individuals may not think that they have "ownership" of their data, or may feel unable to use it themselves because of the complexity or inaccessibility of their data. Privacy concerns may also deter individuals from using their own data.

[0005] US Patent No. 5,399,663 describes a wearable device for providing product recommendations based on biometric information, such as genetic data, of a user. The wearable device incorporates a laser scanner or barcode reader that is used by the wearer of the device to identify products that the wearer is interested in purchasing or consuming. The device then provides an indication of whether the product is recommended to the wearer based on the wearer's biometric information. For example, if a DNA analysis of the user reveals that the user metabolizes caffeine slower than most other people, the wearable device can recommend that the user avoid coffee. However, it is not easily possible for users of the wearable device described in US Patent No. 5,399,663 to compare product recommendations or biometric information with each other. Although two users can, for example, scan the same product and compare whether the indications provided by their respective wearable devices are the same, this process can be cumbersome and does not necessarily enable the users to identify which aspects of their biological or genetic identity are different or have in common. Of course, the users can discuss their biometric information while simultaneously viewing the information on their smartphones. Nonetheless, a quick, almost instantaneous way to compare information is desirable. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] US Patent Application Publication No. 2017 / 0323057 Summary of the Invention [Means for solving the problem]

[0007] According to a first aspect of the present invention, there is provided a wearable device including a memory storing data associated with a user's personal biology, a short-range wireless transceiver for receiving data associated with a fellow user's personal biology from a fellow wearable device, and a processor for comparing the received data with the data stored in the memory to determine whether they match, the device further including an indicator for generating a visual, audio, or other sensory indication of the match when the data is determined to match.

[0008] The device may be operable to receive data from a companion wearable device in response to detecting the companion wearable device within a predefined distance or in contact. Detecting the presence of the other wearable device within a predefined distance of the wearable device may comprise detecting a strength or quality of a signal transmitted from the companion wearable device that exceeds a predefined value. The transceiver may operate using a Bluetooth protocol, preferably a BLE (Bluetooth Low Energy) profile or a short-range wireless communication protocol. The predefined distance may be less than 10 cm, preferably less than 5 cm, or possibly less than 0.5 cm.

[0009] The indicator may be configured to generate a visual, audio, or other sensory indication of the non-match when the data does not match.

[0010] The data associated with a user's personal biology may include one or more scores, each score indicating whether the user is predisposed to or has an associated personal behavior or condition. By way of example, the data may indicate the user's ability to metabolize caffeine, sensitivity to calories and carbohydrates, etc., all of which characteristics are derivable from an analysis of certain portions of the user's genetic makeup.

[0011] A wearable device is a device worn on the wrist and includes, for example, a wrist band or wrist strap.

[0012] The transceiver may be configured to transmit data associated with the user's personal biology stored in the memory to a companion device in response to the companion device being detected to be within a predefined distance or in contact.

[0013] The wearable device may include a sensor, such as an accelerometer, to detect a user input or gesture, and the device is configured to switch, upon detection of such input or gesture, from a first mode in which no data is exchanged with a companion device to a second mode in which data is exchanged.

[0014] The device may include a memory storing a product code and a product code recommendation, and a product code reader for reading the product code from the product. The processor may be configured to obtain a product recommendation for the read product code, and the indicator may be configured to generate a visual, audio, or other sensory indication of the obtained product recommendation. The product code reader may be a bar code scanner.

[0015] The wearable device may be a smartphone.

[0016] According to a second aspect of the invention, there is provided a system for enabling a user to compare data associated with their personal biology with fellow users. The system includes a wearable device according to the first aspect of the invention above, and a computing device in wireless communication with the wearable device, the computing device enabling the user to select data to be matched from a set of data stored in a memory of the wearable device. The wearable device may be a wrist-worn device, and the computing device may be a smartphone. The wearable device may be configured to store information identifying the user and to transfer the information to an app running on the smartphone. When data of two users is determined to match, the users may be added to the app as friends.

[0017] According to a third aspect of the invention, there is provided a computer-implemented method of comparing data associated with a respective user's personal biology stored on respective wearable devices, the method including detecting, by the wearable devices, that the wearable devices are within a predefined distance of each other or in contact with each other, and in response to the detection, exchanging data between the devices over a wireless interface, the method further including comparing the user's data on one or both of the devices to determine whether the data match, and when the data are determined to match, operating an indicator on one or both of the devices to provide a visual, audio, or other sensory indication of the match.

[0018] The method may include providing control over individual selection or non-selection of categories of biometric information to be shared with others through an external computing device, such as a smartphone, in communication with the wearable device. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a schematic system diagram of the wearable device of FIG. 1. [Diagram 3] FIG. 2 is a sequence diagram further illustrating how the wearable device of FIG. 1 can be used to exchange personal biometric information. [Figure 4] FIG. 1 is an explanatory diagram illustrating a schematic user interface for displaying a user's biometric information. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The embodiments described herein aim to address the problems mentioned above by enabling users to compare their personal biometric information in a convenient and secure manner. This personal biometric data is typically data derived from an individual's biology, e.g., genetic traits. The personal biometric information is stored in a wearable device that includes a transmitter and a receiver for transferring the biometric data between the wearable devices when they are brought close to each other or in contact with each other. After the biometric data is exchanged, the wearable device compares the two sets of data to determine aspects of the data that are common to both users and / or differences between the two sets of data. A comparison performed in the wearable device helps ensure a fast and reliable process, e.g., without the need for communication involving a remote server. Of course, this does not preclude the involvement of a remote server (e.g., the "cloud"). The results of the comparison are then presented to the users. For example, a pair of friends / users may each know that they have a gluten intolerance, but without this method, they may not be aware that the other has the same intolerance. The reverse relationship can also occur, where one user has a condition that requires them to avoid eating too much red meat, while the other user is anemic and needs to consume an iron / meat rich diet. A biometric comparison of two users can thus facilitate discussions about how to best manage a particular condition, or to determine a meal they can share or a restaurant that is appropriate for both.

[0021] Enabling users to "share and compare" their biometric information with simple collaborative gestures provides a playful social aspect to what may otherwise seem to them a fairly abstract exercise. For example, when there is a "match" between two users' biometric information, a social connection between the users may be strengthened, or the comparison process may act as an "ice breaker" for further interaction and discussion between the two users. Furthermore, these social aspects can encourage the users to have a stronger awareness of their biological identity and guide or "nudge" them towards making better health and lifestyle decisions.

[0022] The personal biometric data that is compared is not limited to data related to food, but can be extended to any characteristic derived from personal biometric data. For example, the data compared may relate to skin care and cosmetics / functional cosmetics, fitness / activity, smoking, alcohol consumption, etc.

[0023] The personal biometric information of a user may include personal genetic or epigenetic or proteomic data obtained by analysis of a biological specimen (e.g., a buccal swab) provided by the user. For example, the biological specimen may be analyzed using primers, i.e., short strands of nucleic acid sequences that act as starting points for DNA synthesis. As is known in the art, such primers may be used in the detection of genetic single nucleotide polymorphisms (SNPs), and more particularly in determining the variant (or allele) of the individual being tested for a given SNP. Alternatively or in addition, the personal biometric information may include information related to the user's microbiome, such as the presence or absence of a particular gut bacteria (e.g., Helicobacter pylori). Such microbiome data may be obtained by a breath test. The personal biometric information may also include information about the user's physiology (such as the user's current heart rate, or its history), which may in some cases be obtained by a sensing device integrated into the wearable device.

[0024] Personal biometric information may also be derived from one or more of the above types of data. For example, personal biometric data may include recommendations for specific products or services, or classes of products or services, that are found to be particularly suitable for the user or that the user should avoid from an analysis of the above types of data. These recommendations may be derived from biometric filter codes that map to respective products or services or categories of products or services, but do not explicitly identify the user's genetic or biometric information. For example, there may be a biometric filter code that indicates that a user is more likely (due to their genetic traits) to be adversely affected by foods with high cholesterol. In this case, by comparing the biometric filter codes (or the biometric information used to derive the filter codes), users can see whether it is plausible that a similar product or service would be recommended to them. This may foster more interaction and discussion between the users, and may lead to a positive "synergy" where users are more likely to heed product recommendations and / or compare their biometric data.

[0025] FIG. 1 illustrates two users exchanging personal biometric information using wrist-worn wearable devices 100, 102. In the example shown, the gradually widening curved lines indicate information being sent from one device 100 and received by the other device 102. In this case, the BLE (Bluetooth Low Energy) protocol is used for the exchange of biometric information, but other protocols, such as the Near Field Communication (NFC) protocol, designed for data transmission over relatively short distances, can also be used. When the NFC protocol is used, devices are typically required to be within about 5 cm of each other to establish a communication channel between them. An ISP 1507 (NFC & ANT BLE) module based on the nRF52 chip from Nordic Semiconductor is used, which is integrated with a Cortex M4 CPU, flash, RAM memory, and an optimized antenna. The range within which the "connection" is established may be (user) configurable.

[0026] Transmitting personal biometric information over only a short range means that users need to have their devices in relatively close proximity. This reassures users that their data will not be intercepted by a third party (introducing a high degree of privacy) and adds a social element to the process of exchanging biometric information, similar to, for example, a handshake. In some instances, it may be necessary to touch the wearable devices (or "tap" one on the other) to cause or initiate the exchange of data. The biometric information may also be exchanged in encrypted form. For example, the biometric information may be encrypted using a public key associated with the intended recipient and then decrypted using a corresponding private key stored in the recipient's wearable device. Storage of the received biometric information in the recipient's wearable device may also be for only a short period of time (e.g., less than 30 seconds) or no longer than is necessary to perform the comparison.

[0027] FIG. 2 is a schematic system diagram of the wearable devices 100, 102 of FIG. 1. Each wearable device 100, 102 includes a gesture sensor for triggering a mode for exchanging data, a receiver 202 for receiving data 204 according to a wireless communication protocol as discussed above, and a transmitter 206 for transmitting data 208. The gesture sensor, receiver 202, and transmitter 206 communicate with a processor 210 connected to a memory 212 that contains personal biometric information 214 of a user associated with the wearable device 100, 102. In use, the processor 210 retrieves the personal biometric information 214 from the memory 212 and transmits it using the transmitter 206. The personal biometric information 214 received by the receiver 202 may also be stored in the memory 212, allowing the processor 210 to compare the received information 214 with the information 214 of the user.

[0028] FIG. 3 is a sequence diagram illustrating how wearable devices 100, 102 (shown in the figure as “Band 1” and “Band 2”) can be used to exchange personal biometric information. In steps 300 and 300′, the wearer of each band performs an action to put the device into “matching mode”. In this example, a “double tap” gesture is used, which is detected, for example, by an accelerometer / gyroscope in the wearable device (the MPU-6050 has a 3-axis gyroscope and a 3-axis accelerometer coupled to it), but of course other user input gestures or modes, such as buttons or touch screens, can also be used. Each device can stay in matching mode for some predefined period of time, for example 10-15 seconds, after which the matching mode is switched off.

[0029] In steps 301 and 301', each device scans for other devices while advertising itself as available for matching. In steps 302 and 302', each device waits until it finds another device in matching mode. A relative received signal strength indication (RSSI) is measured by each device (steps 303 and 303'). The measured RSSI value is an indication of the power level of the signal each device is receiving from the other. RSSI values ​​are typically provided according to a negative scale starting from -100 and ending at 0, with RSSI values ​​closer to 0 indicating a stronger received signal. Other scales for measuring received signal strength can also be used, such as decibels relative to 1 milliwatt (dBm) or the Received Channel Power Indicator (RCPI) scale that is part of the IEEE 802.11 standard. If the RSSI value exceeds a certain value (e.g., RSSI>-80 or received signal strength of -80 dBm), the devices can connect with each other to exchange vital information (steps 304 and 304'). In the illustrated example, the transfer (exchange) of vital information is unidirectional between the devices.

[0030] One of these devices (here, band 1) receives personal biometric data from band 2. Band 1 then compares the received biometric information with the biometric information stored in its memory and then transmits the result(s) of the comparison to the other device so that both bands can see the result (steps 305 and 305'). The comparison of the personal biometric information of these users can be performed in different ways depending on what type of information is exchanged. For example, if the information relates to certain genes, SNPs, or DNA sequences, the comparison may entail determining whether those genes, SNPs, or DNA sequences are common to both users. Similarly, if the personal biometric information contains a set of biometric filter codes for each user, the sets can be compared to see if there is an overlap. The comparison can also include determining the likelihood that the users have a particular characteristic in common to provide a measure of how likely or rare it is that the users share that characteristic.

[0031] The results of the comparison may be presented to each user (steps 306 and 306'), for example by illumination of a light emitting diode (LED), e.g., a green LED indicates that there is a match between the biometric information of the two users and red indicates no match. Other means for presenting the results of the comparison to the user may also be used, such as a display, a tactile device that applies force or vibration to the wearer of the band, or an audible alarm or voice synthesizer. In one embodiment, each band temporarily stores the results in its RAM memory while it displays the results. After some short period of time, e.g., 10 seconds, the display is turned off and the results are deleted from the memory of both bands.

[0032] Wearable devices tend to have limited means for accepting user input. Thus, the device may be capable of communicating with an external computing device, such as a smartphone, using, for example, a Bluetooth interface. The smartphone may be configured with an app that allows the user to control the settings of the wearable device. FIG. 4 illustrates a graphical user interface 400 for displaying information associated with a user's personal biometric information provided on a smartphone display via an installed app. In this example, the personal biometric information includes a numerical score for a category, such as "calorie sensitivity" or "fat sensitivity." The numerical score is mapped to a user-friendly textual description for presentation in the user interface, such as "very high," "high," "medium," "low," or "slow." The various categories are presented as graphical user elements 401. In some implementations, a user may individually select or deselect these graphical user elements to control whether the biometric information associated with that category shall be shared with other users and / or used in comparing biometric information between users. For example, in FIG. 4, a user has selected four panels for sharing: Caffeine Metabolism, Calorie Sensitivity, Carbohydrate Sensitivity, and Fat Sensitivity (indicated with a "select" in the figure). This type of control can be useful in avoiding the exposure, either directly or indirectly, of information that a user would rather keep private. Comparison of two users' biometric information can involve a comparison of numerical scores in each of the categories to determine whether any of their scores match or are roughly the same, i.e., differ by only a small relative or absolute amount. Alternatively, a weighted difference in scores can be used to define a similarity metric that indicates how "similar" the users are.

[0033] In the event that two peer users select different categories for matching, this may be indicated by illumination of a third color of the LED, for example white, to indicate that the users have no possible match and should consider selecting another category.

[0034] The wearable device can also report the results of the comparison back to the user's smartphone. In cases where the identities of the fellow users are known, this can allow the results to be logged in the smartphone / app. Based on the results of the comparison, users could then plausibly share information about purchased products, fitness, etc. via their smartphone. In other words, the ability to compare bio-related information could form the basis of many different social networking opportunities.

[0035] For example, when two wearable devices match with each other, information identifying a user (e.g., a user identifier) ​​may be transferred from one wearable device to the other. The user identifier may be stored locally within the wearable device and transferred to a mobile app running on a smartphone when the wearable device is synchronized with the application. The two users may, for example, be added as friends in the mobile app when it is determined that their data matches. In a further example, the users may further communicate with each other (e.g., through messaging or networking services that may form part of the mobile app).

[0036] More generally, a user may be added as a member of a social network or invited to join in response to bringing his or her wearable device into close proximity with the wearable device of another user who is already a member of the social network. In some cases, a user may only join or be invited to join a social network if it matches (or perhaps merely attempts to match) with a user who is already a member of the social network. In other cases, both users may be added to the social network even if neither user is already a member. The social network may be configured to add the user as a friend in response to a match being obtained, i.e., a link or "edge" is created in the network that the user joins. The social network may be configured to allow users to compare data with users who are friends of friends without requiring matching using a wearable device, i.e., users may match with other users twice as far away in the social network. This matching may require a user to invite another user to match and for the other user to accept the invitation.

[0037] Although not described in detail herein, the band may be equipped with a product code reader to enable the band to read product codes from products being considered for purchase or consumption. Such a reader may be a bar code scanner and may enable a user to obtain product recommendations based on product data stored within the band.

[0038] As those skilled in the art will recognize, various modifications may be made to the above described embodiment without departing from the scope of the present invention. Of course, it may be the case that only one of two peer users has a band and the other only has a smartphone. In this case, there may be an option in the smartphone app to display a code, such as a barcode, on the smartphone GUI that identifies the user's personal biometric data. The peer user with the band can scan the code using the band's product code reader and perform the comparison described above. Of course, in this case, the result may only be displayed on the band, but this may be sufficient for both users to be able to see the result.

[0039] It will be further appreciated that the present invention may be implemented using a pair of smartphones without the need for a band, provided both smartphones are equipped with suitable short-range wireless transceivers.

[0040] As will also be appreciated, various means may be implemented to place the band into a read-to-match state, for example the band may switch into this mode when a double tap on the other band is detected. [Explanation of symbols]
