Title: Head-mounted device with electronic scent assembly

Description:
FIELD 
     The disclosure below relates to technically inventive, non-routine solutions that are necessarily rooted in computer technology and that produce concrete technical improvements. In particular, the disclosure below relates to head-mounted devices with electronic scent assemblies. 
     BACKGROUND 
     As recognized herein, people might sometimes endure stress and anxiety due to various circumstances. Current electronic devices are insufficient in addressing these issues, and depending on the situation the person might not be able to take other remedial measures to address their stress or anxiety either. Indeed, sometimes operation of the electronic devices themselves can be stress-inducing. As also recognized herein, a requirement to wear a mask in certain situations can be stress-inducing but leave the person with no other option but to endure the stress. There are currently no adequate solutions to the foregoing technological problem. 
     SUMMARY 
     Accordingly, in one aspect a mask device includes a facial covering, at least one processor, an electronic assembly accessible to the at least one processor, and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to identify a trigger based on a biometric of a user and, based on the identification of the trigger, release a scent from the electronic assembly into a space between the facial covering and an area where the user&#39;s nose is disposed while wearing the mask device. 
     In various example implementations, the trigger may include the user&#39;s heart rate surpassing a threshold heart rate, a body temperature of the user surpassing a threshold temperature, and/or the user&#39;s breathing rate surpassing a threshold breathing rate. 
     Additionally, in various example embodiments the electronic assembly may include one or more chambers into which respective scent cartridges are insertable. The scent cartridges may house respective substances having respective scents releasable from the electronic assembly based on identification of the trigger. In some examples the mask device may include the respective scent cartridges themselves. The chambers may provide for an interference fit and/or snap fit of the scent cartridges into the electronic assembly. Additionally, the scent cartridges may be interchangeable by an end-user via removal from and insertion into the chambers. In certain examples, the mask device may also include one or more vents through which the scent is able to travel from the electronic assembly into the space. 
     Still further, in various examples, the at least one mask device may include a mask bearing the electronic assembly and the facial covering and also may include another device that wirelessly communicates with the mask to release the scent. 
     In another aspect, a method includes identifying a trigger for releasing a scent via an electronic assembly engaged with a mask and then, based on identifying the trigger, actuating the electronic assembly engaged with the mask to release the scent into a space between a facial covering of the mask and an area where a user&#39;s nose is disposed while wearing the mask. 
     In some examples, the method may therefore include identifying the trigger based on a biometric of the user, such as a biometric related to a current heart rate of the user and/or a current body temperature of the user. However, the method may additionally or alternatively include identifying the trigger based on execution of a video game, based on presentation of an audio video (A/V) program such as a movie or a television show, and/or based on presentation of music or other audio content. 
     In still another aspect, a scent cartridge receptacle includes a housing engageable with a face mask and/or other head-mountable device, one or more chambers in the housing into which respective scent cartridges are receivable, and electronic circuitry for communicating with at least one processor to release scent from one or more of the respective scent cartridges via the mask and/or other head-mountable device. 
     In some examples, the scent cartridge receptacle may even include the at least one processor itself. 
     The details of present principles, both as to their structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     DETAILED DESCRIPTION 
     Among other things, the detailed description below relates to use of a smart mask to combat anxiety and stress by subtly releasing scents into the user&#39;s vicinity. The mask or connected device may measure the amount of stress in the body by regulation and release a soothing scent depending upon the user&#39;s choice to help them relax. Additionally or alternatively, the mask may be programmed to further immerse a user into a relaxation state by enhancing olfactory senses. Other applications may include enhancing immersion with event-based dispersions within a videogame (e.g., wood or fire scent) or the release of peppermint scents to relax users. 
     In order to monitor a user&#39;s stress level, an additional sensory wristband may be utilized in certain implementations to monitor the heartrate of an individual. When reaching specific heartrates, the wrist sensor may then send a signal to the mask via Bluetooth. The mask may then act accordingly by subtly releasing a scent to the user to help calm him/her. Scent dispersion can be autonomous based on biosignature data captured from other wearables as well (e.g., once heart or respiration rate returns to baseline, scent dispersion may taper off and/or end). 
     Additionally, different scents may be provided and programmed accordingly depending on user preference. Scents can be stored in small cartridges that can be inserted and removed from the smart mask as they run out. This can also be set in a software app that the user can download and configure. Lavender, jasmine, lemon, and other scents may thus be used to combat stress and bring a calm state of mind. 
     Additionally or alternatively, as mentioned above the smart mask may be used to enhance a user&#39;s experience with electronic entertainment such as movies, videogames, and music. Scents can be configured to release at specific times according to the app to enrich the user&#39;s experience and further immerse the user into their entertainment. 
     Prior to delving further into the details of the instant techniques, note with respect to any computer systems discussed herein that a system may include server and client components, connected over a network such that data may be exchanged between the client and server components. The client components may include one or more computing devices including televisions (e.g., smart TVs, Internet-enabled TVs), computers such as desktops, laptops and tablet computers, so-called convertible devices (e.g., having a tablet configuration and laptop configuration), and other mobile devices including smart phones. These client devices may employ, as non-limiting examples, operating systems from Apple Inc. of Cupertino Calif., Google Inc. of Mountain View, Calif., or Microsoft Corp. of Redmond, Wash. A Unix® or similar such as Linux® operating system may be used. These operating systems can execute one or more browsers such as a browser made by Microsoft or Google or Mozilla or another browser program that can access web pages and applications hosted by Internet servers over a network such as the Internet, a local intranet, or a virtual private network. 
     As used herein, instructions refer to computer-implemented steps for processing information in the system. Instructions can be implemented in software, firmware or hardware, or combinations thereof and include any type of programmed step undertaken by components of the system; hence, illustrative components, blocks, modules, circuits, and steps are sometimes set forth in terms of their functionality. 
     A processor may be any single- or multi-chip processor that can execute logic by means of various lines such as address lines, data lines, and control lines and registers and shift registers. Moreover, any logical blocks, modules, and circuits described herein can be implemented or performed with a system processor, a digital signal processor (DSP), a field programmable gate array (FPGA) or other programmable logic device such as an application specific integrated circuit (ASIC), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A processor can also be implemented by a controller or state machine or a combination of computing devices. Thus, the methods herein may be implemented as software instructions executed by a processor, suitably configured application specific integrated circuits (ASIC) or field programmable gate array (FPGA) modules, or any other convenient manner as would be appreciated by those skilled in those art. Where employed, the software instructions may also be embodied in a non-transitory device that is being vended and/or provided that is not a transitory, propagating signal and/or a signal per se (such as a hard disk drive, CD ROM, or Flash drive). The software code instructions may also be downloaded over the Internet. Accordingly, it is to be understood that although a software application for undertaking present principles may be vended with a device such as the system  100  described below, such an application may also be downloaded from a server to a device over a network such as the Internet. 
     Software modules and/or applications described by way of flow charts and/or user interfaces herein can include various sub-routines, procedures, etc. Without limiting the disclosure, logic stated to be executed by a particular module can be redistributed to other software modules and/or combined together in a single module and/or made available in a shareable library. Also, the user interfaces (UI)/graphical UIs described herein may be consolidated and/or expanded, and UI elements may be mixed and matched between UIs. 
     Logic when implemented in software, can be written in an appropriate language such as but not limited to hypertext markup language (HTML)-5, Java/JavaScript, C # or C++, and can be stored on or transmitted from a computer-readable storage medium such as a random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), a hard disk drive or solid state drive, compact disk read-only memory (CD-ROM) or other optical disk storage such as digital versatile disc (DVD), magnetic disk storage or other magnetic storage devices including removable thumb drives, etc. 
     In an example, a processor can access information over its input lines from data storage, such as the computer readable storage medium, and/or the processor can access information wirelessly from an Internet server by activating a wireless transceiver to send and receive data. Data typically is converted from analog signals to digital by circuitry between the antenna and the registers of the processor when being received and from digital to analog when being transmitted. The processor then processes the data through its shift registers to output calculated data on output lines, for presentation of the calculated data on the device. 
     Components included in one embodiment can be used in other embodiments in any appropriate combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged, or excluded from other embodiments. 
     “A system having at least one of A, B, and C” (likewise “a system having at least one of A, B, or C” and “a system having at least one of A, B, C”) includes systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. 
     The term “circuit” or “circuitry” may be used in the summary, description, and/or claims. As is well known in the art, the term “circuitry” includes all levels of available integration, e.g., from discrete logic circuits to the highest level of circuit integration such as VLSI, and includes programmable logic components programmed to perform the functions of an embodiment as well as general-purpose or special-purpose processors programmed with instructions to perform those functions. 
     Now specifically in reference to  FIG.  1   , an example block diagram of an information handling system and/or computer system  100  is shown that is understood to have a housing for the components described below. Note that in some embodiments the system  100  may be a desktop computer system, such as one of the ThinkCentre® or ThinkPad® series of personal computers sold by Lenovo (US) Inc. of Morrisville, N.C., or a workstation computer, such as the ThinkStation®, which are sold by Lenovo (US) Inc. of Morrisville, N.C.; however, as apparent from the description herein, a client device, a server or other machine in accordance with present principles may include other features or only some of the features of the system  100 . Also, the system  100  may be, e.g., a game console such as XBOX®, and/or the system  100  may include a mobile communication device such as a mobile telephone, notebook computer, and/or other portable computerized device. 
     As shown in  FIG.  1   , the system  100  may include a so-called chipset  110 . A chipset refers to a group of integrated circuits, or chips, that are designed to work together. Chipsets are usually marketed as a single product (e.g., consider chipsets marketed under the brands INTEL®, AMD®, etc.). 
     In the example of  FIG.  1   , the chipset  110  has a particular architecture, which may vary to some extent depending on brand or manufacturer. The architecture of the chipset  110  includes a core and memory control group  120  and an I/O controller hub  150  that exchange information (e.g., data, signals, commands, etc.) via, for example, a direct management interface or direct media interface (DMI)  142  or a link controller  144 . In the example of  FIG.  1   , the DMI  142  is a chip-to-chip interface (sometimes referred to as being a link between a “northbridge” and a “southbridge”). 
     The core and memory control group  120  include one or more processors  122  (e.g., single core or multi-core, etc.) and a memory controller hub  126  that exchange information via a front side bus (FSB)  124 . As described herein, various components of the core and memory control group  120  may be integrated onto a single processor die, for example, to make a chip that supplants the “northbridge” style architecture. 
     The memory controller hub  126  interfaces with memory  140 . For example, the memory controller hub  126  may provide support for DDR SDRAM memory (e.g., DDR, DDR2, DDR3, etc.). In general, the memory  140  is a type of random-access memory (RAM). It is often referred to as “system memory.” 
     The memory controller hub  126  can further include a low-voltage differential signaling interface (LVDS)  132 . The LVDS  132  may be a so-called LVDS Display Interface (LDI) for support of a display device  192  (e.g., a CRT, a flat panel, a projector, a touch-enabled light emitting diode (LED) display or other video display, etc.). A block  138  includes some examples of technologies that may be supported via the LVDS interface  132  (e.g., serial digital video, HDMI/DVI, display port). The memory controller hub  126  also includes one or more PCI-express interfaces (PCI-E)  134 , for example, for support of discrete graphics  136 . Discrete graphics using a PCI-E interface has become an alternative approach to an accelerated graphics port (AGP). For example, the memory controller hub  126  may include a 16-lane (x16) PCI-E port for an external PCI-E-based graphics card (including, e.g., one of more GPUs). An example system may include AGP or PCI-E for support of graphics. 
     In examples in which it is used, the I/O hub controller  150  can include a variety of interfaces. The example of  FIG.  1    includes a SATA interface  151 , one or more PCI-E interfaces  152  (optionally one or more legacy PCI interfaces), one or more universal serial bus (USB) interfaces  153 , a local area network (LAN) interface  154  (more generally a network interface for communication over at least one network such as the Internet, a WAN, a LAN, a Bluetooth network using Bluetooth 5.0 communication, etc. under direction of the processor(s)  122 ), a general purpose I/O interface (GPIO)  155 , a low-pin count (LPC) interface  170 , a power management interface  161 , a clock generator interface  162 , an audio interface  163  (e.g., for speakers  194  to output audio), a total cost of operation (TCO) interface  164 , a system management bus interface (e.g., a multi-master serial computer bus interface)  165 , and a serial peripheral flash memory/controller interface (SPI Flash)  166 , which, in the example of  FIG.  1   , includes basic input/output system (BIOS)  168  and boot code  190 . With respect to network connections, the I/O hub controller  150  may include integrated gigabit Ethernet controller lines multiplexed with a PCI-E interface port. Other network features may operate independent of a PCI-E interface. 
     The interfaces of the I/O hub controller  150  may provide for communication with various devices, networks, etc. For example, where used, the SATA interface  151  provides for reading, writing, or reading and writing information on one or more drives  180  such as HDDs, SDDs or a combination thereof, but in any case, the drives  180  are understood to be, e.g., tangible computer readable storage mediums that are not transitory, propagating signals. The I/O hub controller  150  may also include an advanced host controller interface (AHCI) to support one or more drives  180 . The PCI-E interface  152  allows for wireless connections  182  to devices, networks, etc. The USB interface  153  provides for input devices  184  such as keyboards (KB), mice and various other devices (e.g., cameras, phones, storage, media players, etc.). 
     In the example of  FIG.  1   , the LPC interface  170  provides for use of one or more ASICs  171 , a trusted platform module (TPM)  172 , a super I/O  173 , a firmware hub  174 , BIOS support  175  as well as various types of memory  176  such as ROM  177 , Flash  178 , and non-volatile RAM (NVRAM)  179 . With respect to the TPM  172 , this module may be in the form of a chip that can be used to authenticate software and hardware devices. For example, a TPM may be capable of performing platform authentication and may be used to verify that a system seeking access is the expected system. 
     The system  100 , upon power on, may be configured to execute boot code  190  for the BIOS  168 , as stored within the SPI Flash  166 , and thereafter processes data under the control of one or more operating systems and application software (e.g., stored in system memory  140 ). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS  168 . 
     As also shown in  FIG.  1   , the system  100  may include one or more biometric sensors  191  for sensing biometrics of a user consistent with present principles. Thus, the sensors  191  may include, for example, a pulse/heart rate sensor, a blood pressure sensor, a perspiration sensor (e.g., liquid sensor, capacitance sensor, etc.), a body or skin temperature sensor, a lung input/output sensor or other breath sensor (such as a microphone picking up on audible breaths or an atmospheric pressure sensor, motion sensor, or piezoresistive breath sensor), etc. Other examples of biometric sensors include a blood oxygen sensor, a glucose and/or blood sugar sensor, a brain activity sensor, and a retina and/or iris sensor. 
     Still further, the system  100  may include a Bluetooth transceiver and/or other short-range wireless communication interface  193  for use to communicate with paired wearable devices, smart phones, etc. consistent with present principles. For example, one or more publicly-available Bluetooth specifications may be used for Bluetooth communication using the transceiver  193 . Thus, the Bluetooth transceiver  193  may be a classic Bluetooth transceiver and/or a Bluetooth low energy (BLE) transceiver (e.g., Bluetooth 5.0 transceiver) for communicating with other devices using Bluetooth communication protocols. Additionally, as alluded to above the transceiver  193  may also be configured for communicating using other wireless protocols and may therefore establish a Zigbee transceiver, Z-wave transceiver, near field communication (NFC) transceiver, infrared transceiver, a Wi-Fi direct transceiver, and/or wireless universal serial bus (USB) transceiver, for example. 
     Additionally, though not shown for simplicity, in some embodiments the system  100  may include a gyroscope that senses and/or measures the orientation of the system  100  and provides related input to the processor  122 , as well as an accelerometer that senses acceleration and/or movement of the system  100  and provides related input to the processor  122 . Still further, the system  100  may include an audio receiver/microphone that provides input from the microphone to the processor  122  based on audio that is detected, such as via a user providing audible input to the microphone. The system  100  may also include a camera that gathers one or more images and provides the images and related input to the processor  122 . The camera may be a thermal imaging camera, an infrared (IR) camera, a digital camera such as a webcam, a three-dimensional (3D) camera, and/or a camera otherwise integrated into the system  100  and controllable by the processor  122  to gather still images and/or video. Also, the system  100  may include a global positioning system (GPS) transceiver that is configured to communicate with at least one satellite to receive/identify geographic position information and provide the geographic position information to the processor  122 . However, it is to be understood that another suitable position receiver other than a GPS receiver may be used in accordance with present principles to determine the location of the system  100 . 
     It is to be understood that an example client device or other machine/computer may include fewer or more features than shown on the system  100  of  FIG.  1   . In any case, it is to be understood at least based on the foregoing that the system  100  is configured to undertake present principles. 
     Turning now to  FIG.  2   , example devices are shown communicating over a network  200  such as the Internet or a Bluetooth network in accordance with present principles. It is to be understood that each of the devices described in reference to  FIG.  2    may include at least some of the features, components, and/or elements of the system  100  described above. Indeed, any of the devices disclosed herein may include at least some of the features, components, and/or elements of the system  100  described above. 
       FIG.  2    shows a notebook computer and/or convertible computer  202 , a desktop computer  204 , a wearable device  206  such as a smart watch, a smart television (TV)  208 , a smart phone  210 , a tablet computer  212 , an aroma therapy or smart mask  216 , and a server  214  such as an Internet server that may provide cloud storage accessible to the devices  202 - 212 ,  216 . It is to be understood that the devices  202 - 216  may be configured to communicate with each other over the network  200  to undertake present principles. 
     Continuing the detailed description in cross-reference to  FIGS.  3 - 5   , they show the example smart mask  216  in more detail.  FIG.  3    shows a front perspective view of the mask  216 ,  FIG.  4    shows a rear perspective view of the mask  216 , and  FIG.  5    shows a front perspective view of the mask  216  while being worn by an end-user/wearer  301 . 
     As shown in these figures, the mask  216  may include a rigid or non-rigid facial covering  300  that may be made of cloth, mesh, and/or other suitable material. The facial covering  300  may cover all exterior portions of the wearer&#39;s mouth when worn correctly and may, in some examples, include a discrete a nose piece  302  to cover the wearer&#39;s nose from the bottom of the nostrils all the way up to the top of the bridge. Additionally, the mask  216  may include ear straps  304  at respective mask side portions to extend over the wearer&#39;s ears to hold the mask  216  in place on the person&#39;s face. 
     As also shown in  FIGS.  3 - 5   , the mask  216  may include an electronic assembly  306  that may have and/or at least be accessible to a processor and/or electronic storage (not shown). The assembly  306  may also include other electronic circuitry for use consistent with present principles. For example, the assembly  306  may include a scent cartridge receptacle  308  that may include a housing engageable with the mask  216  (and/or other head-mountable device). The housing may be made of plastic, wood, composite materials, one or more metals, and/or other suitable materials. The housing may establish one or more hollow chambers into which respective scent cartridges  310  can be received as inserted by an end-user. For example, the chambers may provide for an interference fit and/or snap fit of the scent cartridges  310  into respective chambers in the housing of the receptacle  308  so that they may interchangeable via an end-user sliding them in and/or snapping/locking them into place and later easily removing them from the chambers by pressing a spring-loaded depressable release button(s) or actuating one or more release tab(s). Thus, the user need not use a specialized tool or any other object for that matter to engage and disengage the cartridges  310  from the receptacle  308  (e.g., other than the user&#39;s fingers). 
     As for the cartridges  310  themselves, they may be cylindrically-shaped tubes if desired, or may be cylindrically-shaped disks in particular to have a low profile/height to remain unobtrusive to the user&#39;s touch and sight while disposed within the receptable  308 . However, the cartridges  310  may be in other shapes as well depending on desired implementation. For example, the cartridges may be cube-shaped or tetrahedron-shaped. But regardless, further note that each cartridge  310  and hence each corresponding chamber in the receptacle  308  need not be the same size so that, for example, a larger cartridge for a more-frequently used scent may be placed into a corresponding larger chamber for closely-receiving that respective cartridge via a snap or interference fit, while a smaller cartridge for a less-frequently used scent may be placed into a smaller corresponding chamber. 
     Note that the electronic circuitry of the assembly  306  may further include other components not shown for simplicity, such as a Bluetooth transceiver for communicating with at least one processor on one or more other devices to release scent from one or more of the respective scent cartridges  310  via the mask as described herein. The electronic circuitry may also include motors, linkage, gears, etc. for the processor on the mask  216  or other device to electronically control the assembly  306  and scent cartridge receptacle  308  in particular to release scent from one or more of the cartridges  310  in the receptacle  308 . RAM, rechargeable batteries, and other system components such as any of those described above in reference to the system  100  may also be included as part of the circuitry of the mask  216 . 
     Additionally, as best shown in  FIG.  4   , the facial covering may have not just an outer vertical sheet for covering the person&#39;s face but in some examples may also have an inner vertical sheet. The inner sheet may include one or more vents  312  through which scent from one or more of the cartridges  310  is able to travel from the electronic assembly  306  (which may be sown, glued, or otherwise integrated into the outer sheet) into a space between the facial covering  300  and an area inside the mask  216  where the user&#39;s nose is disposed while wearing the mask so that the user can smell the scent upon the scent traveling from the assembly, between the two sheets of the facial covering  300 , and ultimately to the user&#39;s nostrils. However, further note that while the two sheets may be sown together or otherwise attached to each other, they may form a single unitary structure of molded rigid or non-rigid material or other material with hollow areas inside for the scent to travel from the assembly  306  to the user&#39;s nose. Other configurations are also possible. 
     As for the scent itself, note that it may be a gas or other airborne substance such as a mist having liquid droplets, for example. While housed in a respective cartridge  310 , the scent may be reduced to or embodied in a solid (e.g., gel) or liquid that emits smell when exposed to the air through a duct or other component on the cartridge that mechanically/electrically opens and closes under control of the linkage in the assembly  306 /receptable  308 . However, the scent may also be embodied as a compressed gas within the cartridge  310  with the pressure forcing exertion of the gas out of the duct when the duct is opened. A compressed liquid may also be used to provide the aforementioned mist, for example. But regardless, note that the duct on each cartridge  310  may be in fluid communication with the vents  312  when engaged with the mask  216  to deliver the scent to the nostrils of the user  301 . 
     Further note that the receptacle  308  itself may be integral with the rest of the assembly  306 , or may be discrete and separate but snap into the assembly  306  via an appropriately-shaped (e.g., circular-shaped) and electrically-connected grommet forming part of the assembly  306 . 
     Now in reference to  FIG.  6   , an example cylindrical scent cartridge  310  is shown in greater detail. As shown, the cartridge  310  may house a substance  600  such as solid, liquid, or pressurized gas as described above and may also include a duct  602  as described above. Though not shown for simplicity, a mechanically and/or electrically-slidable door may cover and uncover the duct  602  under control of a processor to selectively release scent consistent with present principles, though a plug or door on the receptacle  308  itself may also be used to cover and uncover the duct  602  while the cartridge  310  is engaged with the receptacle  308 , if desired. The cartridge  310  may also include one or more tabs  604  that can be pinched together while the cartridge  310  is snapped or otherwise locked into place within the receptacle  308  to release the cartridge  310  and pull it out from the receptacle  308 . However, a spring-loaded button may also be used to release the cartridge  310  from the receptacle  308 , as may other suitable mechanisms. 
     Continuing the detailed description in reference to  FIG.  7   , it illustrates that the user  301  may don a wearable device  700  that may have one or more biometric sensors  702  on an inside surface to contact the user&#39;s skin while the wearable device  700  is worn. For example, the biometric sensor  702  may be a temperature sensor, optical heart rate sensor, electrode hear rate sensor, or other biometric sensor consistent with present principles. The device  700  is illustrated in  FIG.  7    as an electronic bracelet, but note that in other examples the device may be a smart watch, electronic skin patch, or any other suitable wearable device that can measure user biometrics consistent with present principles. The device might also be an implantable device, as another example. But regardless of device type, further note that the device may have system components as described above in reference to  FIG.  1   , including a processor for receiving input from the biometric sensor  702  itself as well as a Bluetooth or other wireless transceiver for communicating with other devices including the mask  216  and a smart phone  800  as shown in  FIG.  8   . 
       FIG.  9    further illustrates. The smart phone  800  is shown while presenting a connection status graphical user interface (GUI)  900  on its display. The GUI  900  includes images and text as shown that indicate that both the wearable device  700  and mask  216  are paired with or otherwise currently connected to the phone  800  via wireless communication consistent with present principles. Thus, in one example implementation the smart phone  800  may receive biometric input from one or more biometric sensors on the wearable device  700  via Bluetooth communication, determine whether to release scent via the mask  216 , and then communicate via Bluetooth with the mask  216  itself to control the mask  216  to release the scent. 
       FIG.  10    illustrates even further via example logic that may be executed by a device such as the smart phone  800  consistent with present principles. However, the logic may also be executed by another type of device such as laptop computer, tablet computer, or any other suitable device being used. The logic might also be executed by the wearable device  700  itself in conjunction with the smart phone  800  or even a remotely-located server in any appropriate combination, or the wearable device  700  may even execute the logic by itself in a two-device implementation where functions otherwise executed by the smart phone  800  are executed by the wearable device  700  as communicating directly with the mask  216  to release scent (e.g., no smart phone is present and instead bi-directional communication is used rather than the three-way communication shown in  FIG.  8   ). As yet another example implementation, the mask  216  or other head-mounted device that is being worn may include its own biometric sensors and perform one or all steps of the logic of  FIG.  10    without communicating with a wearable device, smart phone, etc. In any case, further note that while the logic of  FIG.  10    is shown in flow chart format, other suitable logic may also be used. 
     Now describing the logic itself in more detail, it may begin at block  1000  where the device may monitor one or more biometrics of a user based on input from one or more biometric sensors as described herein. For example, at block  1000  the device may monitor the user&#39;s heart rate, body temperature, and/or breathing rate. Additionally or alternatively, at block  1000  the device may monitor the presentation of content as presented at the device undertaking the logic of  FIG.  10    or another connected/paired device such as a television, video game console, and/or smartphone to eventually release scent at a designated time within presentation of the content. The content may be established by a video game, an audio video (A/V) program such as a movie or television show or streaming Internet video, audio-only music, or other audio content (such as a podcast or other voice recording), or other type of content. 
     From block  1000  the logic may then proceed to decision diamond  1002  where the device may identify whether a trigger exists for scent release. The trigger may be identified based on a biometric of a user passing a threshold for the respective biometric. For example, the trigger may be the user&#39;s current heart rate surpassing a threshold heart rate as sensed via a heart rate sensor, a current body temperature of the user surpassing a threshold temperature as sensed via a temperature sensor, and/or the user&#39;s current breathing rate surpassing a threshold breathing rate as sensed by a breath sensor, any, or all of which might indicate the user undergoing stress that electronic scent release might help alleviate. 
     In addition to or in lieu of the foregoing but also at diamond  1002 , the logic may monitor for other triggers such as a designated time within presentation of any of the content described above being reached. The designated time may be indicated in and/or preprogrammed into the digital file for the content itself so that the device may recognize the time point within the content&#39;s playtime or recognize a predefined occurrence within the content as being reached and then release a designated scent indicated in the digital file. For example, a lemon scent may be programmed for release at the 1:25:02 hour/minute/second mark for a movie, or a smoke/wood scent may be programmed for release whenever a user comes across a virtual fireplace as part of playing a video game. 
     A negative determination may cause the logic to revert back to block  1000  and proceed again therefrom. However, responsive to an affirmative determination at diamond  1002  that a trigger has been identified, the logic may proceed to block  1004 . At block  1004  the device may identify a particular scent to release (e.g., based on user preference, based on device or application programming, based on a scent specified in the digital file of the content, etc.). The logic may then proceed to block  1006  where the device may actuate an electronic assembly on the mask (e.g., the assembly  306 ) to release the identified scent via the electronic assembly consistent with the disclosure above. For example, if the device executing the logic of  FIG.  10    is a smart phone, the smart phone may issue a command over Bluetooth to the mask to release the scent. Or if the device executing the logic of  FIG.  10    is the mask itself, the mask may itself control the circuitry of its electronic assembly to release the scent. 
     From block  1006  the logic may then proceed to decision diamond  1008 . At diamond  1008  the logic may determine if the trigger still exists. For example, at diamond  1008  the logic may determine whether a given biometric is still above the corresponding threshold or whether the point in the content&#39;s presentation at which the scent should be released or continue to be released is still ongoing. An affirmative determination at diamond  1008  may cause the logic to revert back to block  1006  to continue releasing the identified scent. 
     However, if the point in the content has passed where scent is to be released or the user&#39;s biometric goes back below the corresponding threshold, a negative determination may be made instead and the logic may therefore proceed to block  1010  where the device may control the electronic assembly on the mask to stop releasing the scent identified at block  1004  (e.g., stop releasing scent altogether or begin releasing another scent as appropriate). From block  1010  the logic may revert back to block  1000  and proceed therefrom. 
     Further describing example triggers that might trigger the device(s) of  FIG.  10    to release scent, in some examples the trigger may be established by a user command to release a particular scent. The command may be received via selection of a depressable or touch-enabled button on the mask itself (or connected wearable device) to release a designated scent where, for example, there are multiple buttons on the mask (or separate wearable) that are each associated with a different respective chamber/cartridge for the user to thus be able to choose which scent to release. For example, each cartridge on the mask may itself be depressable inward toward the user&#39;s face under spring bias to establish a button for scent release. Additionally or alternatively, the button may be presented as part of a GUI presented on the display of the wearable device or connected smartphone, as will be described later. 
     Also note that a trigger for scent release might be a biometric of the user going below a certain biometric threshold rather than above it. For example, in addition to or in lieu of releasing a lavender, jasmine, lemon, pine, or peppermint scent for relaxation if a user&#39;s heart rate goes above a first threshold heart rate, if the user&#39;s heart rate goes below a different low heart rate threshold, then another type of scent may be released such as a scent generated by smelling salts in one of the mask&#39;s cartridges. The smelling salts may be established by ammonia inhalants such as a combination of ammonium carbonate and perfume, for example. Thus, if the user&#39;s heart rate drops past the lower threshold due to the user falling asleep, fainting, or otherwise losing consciousness, the smelling salts might help wake the user up. 
     Continuing the detailed description in reference to  FIG.  11   , suppose a user inserts one or more new scent cartridges into a scent cartridge receptacle as described above. The circuitry within the mask may detect as much, e.g. using optical presence sensors or a detected electrical current change based on the cartridge(s) being inserted to contact or complete an electrical path within the circuitry. Responsive to detecting scent cartridge insertion, the GUI  1100  may be presented on a display such as the display of the wearable device or smart phone in communication with the mask. 
     As shown in  FIG.  11   , the GUI  1100  allows a user to indicate to the device(s) which scent cartridges have which scents for the device to then control scent release from the corresponding chamber into which the cartridge has been inserted. The chambers themselves may be visually numbered on the mask itself, for example, so that the user would know which scent cartridge is being inserted into which chamber. The user may then select a corresponding selector  1102 - 1106  for each respective chamber which in turn may cause a drop-down menu or other GUI element to be presented from which the user can select a particular scent to be associated with that respective chamber. However, notwithstanding  FIG.  11   , further note that in some examples the smart mask or connected device may auto-detect scents as well based on various configurations of the cartridges themselves if desired (e.g., passive RFID communication using a passive RFID tag on the cartridge and active RFID transceiver on the mask&#39;s electronic assembly). 
       FIG.  12    then shows that a GUI  1200  may be presented on the display for a user to provide a command to release a particular scent at a time of the user&#39;s choosing after the user has indicated which scent cartridges are engaged with which chambers, or after the device auto-detects as much. For example, the GUI  1200  (and the other GUIs described herein for that matter) may be presented as part of an application (“app”) executing at the user&#39;s smart phone to control the electronic assembly of the mask. Thus, the GUI  1200  may be invoked at the user&#39;s choosing by launching the app, and either having the GUI  1200  automatically presented or navigating to it within the app itself. 
     As shown in  FIG.  12   , the GUI  1200  may establish a scent cartridge control panel where the user may provide a command to release a designated scent associated with a respective selector/button  1202 - 1206  by selecting the associated button via touch or cursor input for example. In the example shown, the scents are lavender, pine, and jasmine. The selected scent may continue to be released until the respective selector  1202 - 1206  is selected again, and/or the scent may be released for a threshold time responsive to the initial selection of the selector  1202 - 1206  and the mask may then stop releasing the scent after expiration of the threshold time. The threshold time might be five seconds, for example. 
       FIG.  13    illustrates that responsive to the mask or other device detecting that a given scent cartridge is empty (e.g., using an infrared proximity sensor or other optical sensor if the cartridge&#39;s housing is transparent), a GUI  1300  may be presented. As shown in  FIG.  13   , the GUI  1300  may include an indication  1302  that lavender scent has run out or is otherwise no longer available via the corresponding cartridge as disposed in a certain chamber (“chamber  1 ” in this example). The indication  1302  might also specify the particular scent associated with that cartridge as also shown. The user may then elect to select selector  1304  to use pine scent from another cartridge that is currently engaged with the mask in instances where the depleted lavender scent would otherwise be released. Additionally or alternatively, the user may select the selector  1306  to launch an online portal through which more lavender or other cartridges may be ordered. 
     Continuing the detailed description in reference to  FIG.  14   , it shows an example settings GUI  1400  that may be presented on a display based on a user navigating the app described above so that the user may configure one or more settings of the device/mask/app to execute consistent with present principles. Note that in the present example, each of the options to be discussed below may be selected by directing touch or cursor input to the respective check box adjacent to the respective option. 
     As shown in  FIG.  14   , the GUI  1400  may include a first option that may be selectable to set or configure the device/mask/app to undertake present principles. For example, the option  1402  may be selected to enable the mask to, for multiple instances in the future, perform the scent-release functions described above in reference to  FIGS.  3 - 9   , execute the logic of  FIG.  10   , etc. 
     The GUI  1400  may also include a setting  1404  at which a user can specify a particular scent to use for stress relief, where stress might be detected based on a certain biometric like current heart rate going above a heart rate threshold. Thus, the user may select the selector  1406  to select lavender as the associated scent or may select the selector  1408  to select pine as the associated scent. However, other available scents may be listed and presented if available. 
     The GUI  1400  may also include respective options  1410 - 1414  to select respective particular biometrics for which the device/mask/app is to monitor for scent release consistent with present principles. As shown in  FIG.  14   , the option  1410  may be selected to use heart rate as the biometric and may even be accompanied by an input box  1416  at which the end-user himself or herself can enter numerical input to establish the threshold/trigger for scent release as a user-designated number of beats per minute. Likewise, the option  1412  may be selected to use temperature as the biometric and may be accompanied by an input box  1418  at which the end-user can enter numerical input to establish the threshold/trigger for scent release as a user-designated temperature in Fahrenheit (or Celsius). The option  1414  may be selected to use breath rate as the biometric and may be accompanied by an input box  1420  at which the end-user can enter numerical input to establish the threshold/trigger for scent release as a user-designated number of breaths per minute. Additionally, note that the GUI  1400  may include another option  1422  to select a certain point or event within content presentation to use as a trigger for scent release as well. 
     If desired, the GUI  1400  may even include a setting  1424  at which the user may establish a particular amount of scent to be released responsive to a trigger. The user may do so by directing numerical input to input box  1426  for example, where the numerical input establishes a scent amount of a particular number of micrograms per meter cubed. Still further, in some examples the GUI  1400  may also include a selector  1428  to initiate a pairing process where one or more of the masks, wearable, and/or smartphone (or other device) may be paired with one another for Bluetooth or other wireless communication to operate consistent with present principles. 
     Moving on from  FIG.  14   , note that present principles may apply not just to masks but also to other head-mounted devices (HMDs) with corresponding scent-release electronic assemblies like the assembly  306 . For example, smart glasses, an augmented reality (AR) headset, mixed reality (MR) headset, virtual reality (VR) headset, or another type of HMD might include an electronic assembly like the assembly  306  to release scent in the vicinity of the user&#39;s nose (e.g., even if the nose is not covered by a facial covering). Biometric sensors for sensing biometrics as discussed above might also be disposed on those HMDs just as they might on a mask. Further note that biometric sensors on a smart phone or other coordinating device may also be used in certain situations consistent with present principles. 
     Also note consistent with present principles that in some examples, a vibrator on the mask/HMD, other wearable device, or smart phone may even be actuated responsive to each instance of scent release. This may be done to provide a haptic notification to the user that the scent is being released so that, for example, the user does not confuse the released scent with an ambient scent from elsewhere in the user&#39;s environment. 
     Further note that in some examples, scent cartridges may include various base or primary scents that can be dynamically mixed and matched with scents from other cartridges to produce a desired scent. For example, a relational database indicating various primary scent amounts to release from each cartridge at the same time to create a desired hybrid scent may be accessed to determine scent amounts to then actually release. 
     It may now be appreciated that present principles provide for an improved computer-based user interface that increases the functionality and ease of use of the devices disclosed herein. The disclosed concepts are rooted in computer technology for computers to carry out their functions. 
     It is to be understood that whilst present principals have been described with reference to some example embodiments, these are not intended to be limiting, and that various alternative arrangements may be used to implement the subject matter claimed herein. Components included in one embodiment can be used in other embodiments in any appropriate combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged, or excluded from other embodiments.
