DETAILED DESCRIPTION
In the following description, reference is made to the accompanying FIGS. 1-7, which show by way of illustration exemplary embodiments of the invention. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments can include structural, logical, or electrical changes without departing from the scope of the invention. The following description of exemplary embodiments is, therefore, understood to not be limiting, with the scope of the invention being defined by the appended claims.
Functions or algorithms described herein may be implemented by software or a combination of software and human implemented procedures. The software can include computer executable instructions stored on computer readable media or computer readable storage device, such as one or more memory or other type of hardware based storage devices, either local or networked. Further, such functions can correspond to modules, which are software, hardware, firmware, or any combination thereof. In some embodiments, multiple functions can be performed in one or more modules as desired, with these embodiments being merely examples. The software can be executed on a digital signal processor, ASIC, microprocessor, or other type of processor operating on a computer system, such as a personal computer, server, mobile devices, or other computer systems.
In an embodiment shown in FIG. 1, a distributed headset 100 is a wireless enabled voice recognition device that utilizes a hands-free profile, where increased battery life is obtained by off-loading elements of the traditional headset into an external electronics module 110 (“module”). The external module 110 is coupled to a light-weight and comfortable headset 115 secured to a worker head via a headband 117. The headband 117 can be a band that is designed to be secured on a worker's head, in an ear, over an ear, or the like. In an embodiment, the headset 115 includes one or more speakers 120 and one or more microphones 125, 126. In an embodiment, microphone 125 is a conventional microphone that converts sound waves into analog signals. Microphone 126 can be one or more microphones that provide for noise cancellation continuously receiving and blocking environmental sounds to enhance voice recognition and optionally provide for noise cancellation.
The external electronics module 110 houses several components typically incorporated in a conventional headset. Thus, the distributed headset 100 reduces the weight of the headset 115 by incorporating heavier components, such as the battery, into the external module 110. In the embodiment shown in FIG. 1, the external module 110 houses one or more of a rechargeable or long life battery, keypad, Bluetooth® antenna, and printed circuit board assembly (PCBA) electronics. The module 110 can include a lapel clip or a lanyard to facilitate attachment of the module 110 to the worker's torso.
In the embodiments shown in FIGS. 1 and 2, the headset 115 attaches to the external electronics module 110 via a communication link 130, such as a small audio cable 130a shown in FIG. 1, or wireless link 130b shown in FIG. 2. The distributed headset 100 provides a flexible use case across multiple workflows in multiple markets, such as grocery retail, direct store delivery, healthcare, etc. In some embodiments, the distributed headset 100 has a low profile and is not intimidating to a customer in a retail setting. Thus, in some embodiments, the headset 115 may be minimalistic in appearance in some embodiments.
In an embodiment, the cable 130a electrically connects the battery in the module 110 to the headset 115 and provides a source of power to the headset 115.
In an embodiment, module 110 can be used with different headsets, such as Honeywell VocollectTM headsets, depending on environment.
In an embodiment, the electronics module 110 can detect a unique identifier (I.D.) of the headset 115, which may be stored in a headset electronic circuitry package 135 supported by headband 117. In an embodiment, the headset electronic circuitry package 135 includes a memory 136 that stores the unique identifier of the headset 115. The headset electronic circuitry package 135 electronically couples the memory 136, speakers 120, and microphones 125 to the electronics module 110. In an embodiment, the audio cable 130 includes multiple conductors or communication lines for signals which may include a speaker +, speaker −, ground digital, microphone, secondary microphone, microphone ground, among others. The module 110 optionally utilizes a user configurable attachment 140, such as a plastic loop, and attachment position on the worker. In embodiments comprising a wireless link between the headset 115 and module 110, such as BluetoothTM type of communication link, the headset 115 includes a small, lightweight battery, where the communication link 130 provides wireless signals suitable for exchanging voice communications.
In the embodiment shown in FIG. 2, an architecture 200 of distributed headset system 100 provides communications to a worker. The architecture 200 includes the headset 115 and external electronics module 110. Module 110 may be coupled to a server or other device, such as a terminal 210 via a wireless link 215, such as a Bluetooth® connection. The terminal 210 can be further coupled to a network 220 via a wireless or wired connection 225, such as WLAN, or other common wireless protocols, and further coupled via a wired or wireless connection 230 to a voice console 235. The voice console 235 assigns an operator to the terminal 210. Voice templates can be stored in terminal 210 to recognize worker voice interactions and convert the interaction into text based data and commands. The data and commands can interact with an application running on the terminal 210. Those of ordinary skill in the art would appreciate the functions ascribed to individual elements of the architecture 200 can be performed in one or more locations. For example, in an embodiment, the terminal 210 can perform voice recognition, or in another embodiment, the module 110 can perform voice recognition utilizing the voice templates. In an embodiment, first stages of voice recognition can be performed by the module 110, with later stages being performed on the terminal 210. In an embodiment, raw audio is transmitted from the module 110 to terminal 210 where the later stages of recognition are performed.
In an embodiment shown in FIG. 3, a method 300 of identifying a headset 115 is described as follows. The headset 115 is detected at block 310 as being attached or otherwise communicatively coupled to the module 110, such as by pluggable multi-line connector or wireless pairing. At block 315, a unique I.D. is read from a one wire electrically erasable programmable read-only memory (“EEPROM”), such as memory 136 positioned either in a headset 115 connector or the headset circuitry package 135. The wire can provide a voltage signal that provides power to read the EEPROM when plugged in. At block 320, the unique I.D. is sent over the wireless connection 215 to the terminal 210, and at block 325, from the terminal 210 to the voice console 235. At block 330, the voice console 235 uses the I.D. to assign a worker to the terminal 210. Templates corresponding to the worker are then downloaded at block 335 to the terminal 210, from the voice console 235, once the worker has been assigned to the terminal 210.
In an embodiment shown in FIG. 4, the module 110 can include a housing 111, such as plastic case, and a connector 410a to receive a complimentary mating connector 410b positioned on a terminating end of the audio cable 130. An internal path 415 communicates between multiple components within the housing 111. In an embodiment, an input speech pre-processor (ISPP) 420 converts input speech into pre-processed speech feature data. An input speech encoder (ISENC) 425 encodes input speech for transmission to a remote terminal for reconstruction and playback and/or recording. A raw input audio sample packet formatter 430 transmits the raw input audio to a remote terminal (not shown) using an application-layer protocol to facilitate communications between the voice terminal 210 and headset 115 as the transport mechanism. For the purposes of the transport mechanism, the audio formatter 430 may be abstracted to a codec type referred to as Input Audio Sample Data (IASD). An output audio decoder (OADEC) 435 decodes encoded output speech and audio for playback in the headset 115. A raw output audio sample packet reader 440 operates to receive raw audio packets from the remote terminal using the transport mechanism. For the purposes of the transport mechanism, this formatter may be abstracted to a codec type referred to as Output Audio Sample Data (OASD). A command processor 445 adjusts the headset hardware (e.g., input hardware gain level) under control of the remote terminal. A query processor 450 allows the remote terminal to retrieve information regarding headset 115 operational status and configuration. Path 415 is also coupled to network circuitry 455 to communicate via wired or wireless protocol with terminal 210. The ISPP 420, ISENC 425, and raw input audio formatter 430 are sources of communication packets used in the transport mechanism; the OADEC 435 and raw output audio reader 440 are packet sinks. The command and query processors 445, 450 are both packet sinks as well as sources, since they typically generate acknowledgement or response packets.
In an embodiment shown in FIG. 5, a computer system 500, or computing device, implements components and methods of the distributed headset 100. While the following description of the computer system 500 includes a variety of components, those of ordinary skill in the art would appreciate that embodiments of the invention can include any combination of one or more of the described components. In an embodiment the computing device 500, includes one or more of a processing unit 502, memory 503, removable storage 510, and non-removable storage 512. The computing device 500 can be a computer, a smartphone, a tablet, a headset, a smartwatch, or other computing device including the same or similar elements as illustrated and described with regard to FIG. 5. Devices such as smartphones, tablets, headsets, and smartwatches are generally collectively referred to as mobile devices. Further, although the various data storage elements are illustrated as part of the computer 500, the storage may also or alternatively include cloud-based storage accessible via a network, such as the Internet.
Memory 503 can include volatile memory 514 and non-volatile memory 508. Computer 500 may include—or have access to a computing environment that includes—a variety of computer-readable media, such as volatile memory 514 and non-volatile memory 508, removable storage 510 and non-removable storage 512. Computer storage includes random access memory (RAM), read only memory (ROM), erasable programmable read-only memory (EPROM) & electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, compact disc read-only memory (CD ROM), Digital Versatile Disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium capable of storing computer-readable instructions known to those of ordinary skill in the art.
In another embodiment shown in FIG. 5, the computer 500 can include or have access to a computing environment that has an input 506, output 504, and a communication connection 516. Output 504 includes a display device, such as a touchscreen, that also may serve as an input device. The input 506 can include one or more of a touchscreen, touchpad, mouse, keyboard, camera, one or more device-specific buttons, one or more sensors integrated within or coupled via wired or wireless data connections to the computer 500, and other input devices. In an embodiment, the computer 500 can operate in a networked environment using a communication connection to connect to one or more remote computers (not shown), such as database servers. The remote computer can be a personal computer (PC), server, router, network PC, a peer device or other common network node, or the like commonly known to those of ordinary skill in the art. The communication connection can be a Local Area Network (LAN), a Wide Area Network (WAN), cellular, WiFi, Bluetooth, or other commonly known networks.
Computer-readable instructions stored on a computer-readable medium are executable by the processing unit 502 of the computer 500. A hard drive, CD-ROM, and RAM are examples of articles, including a non-transitory computer-readable medium like a storage device. The terms “computer-readable medium” and “storage device” generally excludes carrier waves. For example, a computer program 518 capable of providing a generic technique to perform access control check for data access and/or for doing an operation on one of the servers in a component object model (COM) based system can be included on a CD-ROM and loaded from the CD-ROM to a hard drive. The computer-readable instructions allow computer 500 to provide generic access controls in a COM based computer network system having multiple users and servers.
In the embodiments shown in FIGS. 6 and 7, the module 110 has an exemplary tag 600 positioned on a front surface. The tag 600 can be integral with the housing 111 of the module 110, or can be a separate component permanently or releaseably attached to the housing 111. The tag 600 can have information printed on an outer facing surface opposite the module 110, such as the worker's name 615, additional text 625 such as the worker's position or responsibility, and/or a company identifier 630. Other information may be included as desired, such as logos or other markings identifying the worker as an employee of the retail store. A receiving opening 635 can be positioned on an edge of the tag 600, and used to receive a clip or lanyard for wearing by the worker as a lapel or hanging name tag in various embodiments.
Those of ordinary skill in the art would appreciate that the information presented on the tag 600 can change significantly in different embodiments, and can be designed to be helpful to customers in a retail setting without being intimidating. As an example, in one embodiment, the tag 600 can be used for a retail store, and has a front surface with an area large enough to conceal the module 110, attached to a back side of the name tag 600. Such concealment helps create a less intimidating appearance and helps customers feel free to interact with a worker wearing such a tag 600.
In some embodiments, the module 110 has a wired or wireless communication link, such as a Bluetooth short range communication mechanism, to interact with the headset 115 or even an ear phone type device to interact via voice with the module 110 and further provide the worker with an approachable appearance to customers in a retail environment.
In an embodiment shown in FIG. 8, a method 800 performed by the electronic module 110 coupled to the tag 600 includes the step of covering the module 110 from view by the tag 600 at block 700. At block 710, a read signal is provided to a headset when the headset is communicatively coupled to the electronic module. At block 720, a unique identifier is received from the headset based on the read signal. The unique identifier is transmitted to a terminal at block 730 to uniquely identify a user associated with the headset and to identify corresponding voice templates. At block 740, assignment instructions are sent to the headset through the electronic module 110 from to the remote terminal following receipt of the unique identifier. At block 750, voice instructions are provided to the headset 115 by the remote terminal through the electronic module 110 after the electronic module has identified the unique identifier. At block 760, voice communication from the user is received by the remote terminal from the headset 115 via the module 110.
Although a number of exemplary embodiments have been described in detail above, those of ordinary skill in the art would appreciate that other modifications are possible. For example, the logic flows depicted in the Figures do not require the particular order shown, or sequential order, to achieve desirable results. Other steps may be provided, or steps may be eliminated, from the described flows, and other components may be added to, or removed from, the described systems. Thus, various combinations of the described embodiments can be combined to give other embodiments within the scope of the following claims.
