Patent Application
20160066297
The present disclosure relates generally to mobile communication and more particularly to vibratory alerting in response to reception of a message in environments where a user's hearing and/or tactile sense may be degraded due to hearing protection, loud ambient noise levels, or both.
Mobile communication devices are in widespread usage, particularly in the form of “smart” cellular telephone devices. It is common for such devices to have a “silent” ring mode where, upon receiving a message, or an indication of an incoming phone call, a vibration motor is activated to cause the device to vibrate. Typically in such cases no audible alert (i.e. ringing) is used, although both can be used together if selected by the user of the device.
A common design goal with such devices is, generally, to reduce their size and weight, subject to other design choices such as, for example, display size. This tends to limit the efficacy of vibration devices, leading to people not noticing when the device is vibrating under many conditions. For example, a smartphone carried in a user's pocket while operating a motor vehicle in traffic can result in insufficient vibration and distraction such that the user may not notice the smartphone vibrating in response to an incoming phone call. In louder environments, such as construction sites, where communication can be crucial at times, the vibrations of machinery and construction activities can mask the vibration of a typical smartphone vibration motor completely so that the user does not get alerted to incoming communications.
Accordingly, there is a need for a method and apparatus for providing vibratory alerts in a way that overcomes the masking effects of ambient conditions without interfering with the generally desirable design goals of mobile communication devices.
In the accompanying figures like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, and are incorporated in and form part of the specification to further illustrate embodiments of concepts that include the claimed invention and explain various principles and advantages of those embodiments.
Those skilled in the field of the present disclosure will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
The apparatus and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. The details of well-known elements, structure, or processes that would be necessary to practice the embodiments, and that would be well known to those of skill in the art, are not necessarily shown and should be assumed to be present unless otherwise indicated.
Embodiments as disclosed herein solve the problems associated with the prior art by use of a vibration accessory that can be coupled to a communication device that includes a vibration alert application. The vibration accessory, being separate from the communication device and not subject to size constraints used in the design of the communication device by the manufacturer of the communication device uses a much stronger vibration motor that that used in communication devices to generate vibrations having substantially more amplitude than is possible with conventional vibration motor used in communication devices. Some embodiments include a vibration alert system that comprises a vibration accessory having a local wireless interface circuit, a controller coupled to the local wireless interface circuit, a memory coupled to the controller, and a vibration motor controlled by the controller. The system further includes a communication device having a local wireless interface circuit that establishes a local wireless link with the local wireless interface circuit of the vibration accessory, and a wide area radio communication transceiver. The communication device receives messages over the wide area radio communication transceiver and transmits alert messages to the vibration accessory via the local wireless link. The vibration accessory, in response, controls the vibration motor according to a vibration pattern selected from a plurality of vibration patterns where the vibration pattern is selected based on a category of the alert message transmitted to the vibration accessory by the communication device.
The communication device 102 contains a vibration alert application 112, which is a program that can be instantiated and executed by the communication device 102, and causes the communication device 102 to perform functions, operations, and behaviors in accordance with the teachings herein. The communication device 102 and the vibration alert accessory 104 are communicatively linked. In some embodiments the link 108 can be a wired link, such as through an audio jack or port of the communication device 102, a serial connection such as a Universal Serial Bus (USB), or other similar wired connections. Using an audio port wired connection, the communication device 102 can generate audio signals of certain frequencies as control signals that can be decoded by the vibration alert accessory 104.
In some embodiments the link 108 can be achieved using a local wireless radio protocol, such as, for example, a wireless link in accordance with the Institute of Electrical and Electronic Engineers (IEEE) specification no. 802.11 (known in industry as “WiFi”), or 802.15 (e.g. the protocol commonly known by the tradename “BlueTooth”), or other similar low power, low range radio communication protocols. The vibration alert accessory 104 can have an identifier that is shared with the communication device 102 so that the communication device 102 and vibration alert accessory 104 can identify each other in wireless communications. The identifier can be, for example, the media access control (MAC) address of each device's respective network interface circuit, as is known.
Because the vibration alert accessory 104 is not subject to the design constraints (e.g. low weight, thin or small volume) of the communication device 102, it uses a more robust vibration system than can be placed in communication devices, which obviates the need for a larger communication device 102 that does incorporate such a vibration system. Accordingly, the vibration alert accessory 104 can produce vibrations having amplitude on the order of 5-10 times or more than that of a typical vibration motor used in communication devices. The vibration alert accessory 104 can include a clip 105 on an external portion of a housing of the vibration alert accessory 104 so that it can be clipped onto a user's clothing in a place that will help ensure the user/wearer feels vibrations produced by the vibration alert accessory 104. Other form factors can be employed as well, where, for example, the vibration alert accessory can be formed into a helmet or as a bracelet or anklet, for example.
Briefly, the communication device 102, upon receiving a message (i.e. call alert, voice communication, short message system or “text” message, etc.), transmits an alert message to the vibration alert accessory 104 over link 108 (either wired or wireless). In some embodiments the communication device 102 analyzes the received message to determine a category or other classification of the message and selects or indicates a corresponding alert pattern to be used by the vibration alert accessory 104, and indicates the category in the alert message sent via link 108. The vibration alert accessory 104, upon receiving the vibration alert message, carries out the vibration alert in accordance with the indicated category or classification, using the corresponding vibration pattern. The different vibration patterns allow the user to determine the general nature of the incoming message received by the communication device 102 without having to look at the communication device 102. In some embodiments the vibration alert message can indicate an immediate emergency, prompting the user to take action. In some embodiments the vibration alert accessory 104 can include a user input means, such as a button 107, to indicate that the user has detected the alert. The vibration alert accessory 104 can, upon receiving such user input, can transmit an indication of the input to the communication device 102 so that the vibration alert application can make note that the user has acknowledged the alert. The communication device 102 can, in response, transmit an indication of the user's acknowledgement of the alert to an administrator server 114 or other similar entity to record the user's acknowledgment of the alert. The administrative server 114 can be a backend server operated by an entity with which the user of the communication device 102 is associated, and can be connected to the wide are radio communications network 106 via a wide area data network 116 such as, for example, the Internet. In another embodiment, the vibration pattern is preselected by the user according to its level of priority and per contact name or groups of contacts.
The battery 206 can be a rechargeable battery that can be removed and charged in a separate charger, or charged by connecting the vibration alert accessory 202 to a charger, either by wire or by wireless coupling (e.g. inductive charging). In some embodiments, the battery can consist of multiple non-rechargeable alkaline cells. The controller 208 can periodically send battery status messages to the vibration alert application 203 to be displayed on the communication device 204 so that the user can see the charge remaining in the battery 206.
In some embodiments the vibratory system can include a mass that is linearly oscillated back and forth along an axis. For example, a toroidal permanent magnet can be mounted on a rod with biasing springs on either side to urge the toroidal magnet into a center of the rod. Windings of opposing polarities can be wound around respective halves of the rod, allowing the toroidal magnet to move inside the windings. By passing current through one of the windings a magnetic field is created that causes the toroidal magnet to move. Thus, by varying the magnitude of the current, that magnitude of the magnetic force acting on the toroidal magnet can be varied, allowing different magnitude (i.e. force) of the vibration of the toroidal magnet. By alternating the energizing of the coils, the toroidal magnet can be thus caused to oscillate back and forth on the rod in a way that allows independent control of magnitude and frequency of the oscillations.
Four exemplary vibration patterns, 306, 308, 310, 312, 313 are shown. Many other such patterns can be formed in accordance with the teachings herein. The patterns can be periodic, and repeated one or more times by the vibration alert accessory. In exemplary pattern 306 during a first portion 314 a series of pulses 318 occur where, in each pulse, the vibration motor is turned from an off state to an on state at a selected amplitude. Then during a second portion 316 no pulses occur and the vibration motor remains off. The pattern can repeat portions 314 and 316. In some embodiments the vibration pattern can be repeated for a preselected period of time or until a user input is received indicating acknowledgement of the vibration alert. The number of pulses can be varied for other patterns to be used for other alerts. For example, a user can give priority to various contacts in an address book on the user's communication device. Contacts can be given a priority from 1 to 4, which can correspond to vibration patterns using 1 to 4 pulses in portion 314. Pattern 308 shows an example of a pattern similar to that of pattern 306, but with more pulses having shorter duration per pulse, and possibly at a different amplitude. Pattern 310 shows an example of one long pulse followed by an off period. Pattern 312 utilizes ramp up 322 and ramp down 324 segments, and a constant amplitude portion 325. During the ramp up and ramp down segments 322, 324 the vibration amplitude increases over time and decreases over time, respectively. In pattern 313 the vibration is continuous, but the magnitude is periodically varied from times of relatively high magnitude 326 and times of relatively lower magnitude 328. Other patterns can exist that change over time. For example, a vibration alert can start with a relatively low magnitude and ramp up in magnitude until receiving an acknowledgement input from the user. Likewise, patterns can be mixed; for example, a ramp can be followed by a series of pulses.
As mentioned various combinations of pulse length, ramp length, amplitude, and pattern period can be used to create unique vibration patterns, which can be assigned to different categories of incoming messages. Both the duty cycle and vibration magnitude can be modulated in various ways to create unique patterns that can be discerned though tactile sensation by a user wearing the vibration alert accessory. In some embodiments the vibration alert application on the communication device can allow a user to select vibration patterns for various categories (a particular contact in the user's address book can be considered to be a category). In some embodiments the vibration alert application on the communication device can allow a user to create vibration patterns which can be stored and assigned to a category by the user.
In some embodiments the communication devices 502, 514 can include a message analyzer function that analyzes the content of the message to determine if there is an indication of a special condition that requires a special alert. For example, if the received message is a speech message, as in a PTT voice signal, the message analyzer can include a voice analyzer that determines whether the speaker's voice indicates stress or commands. For example, the user of the first communication device 502 can see a condition which presents an imminent threat to the user of the second communication device 514, and using the PTT function can yell “LOOK OUT!” The emphatic nature of the speech can be detected by the message analyzer of the second communication device 514 and in response, the second communication device 514 can send an alert message 518 to the vibration alert accessory that corresponds to an imminent danger so that the user of the second communication device 514 can survey the situation and take appropriate action. In some embodiments the message analyzer can examine the contents of a received text message for code words or commands that require special alerts, and indicate such in the alert message sent to the vibration alert accessory.
A voice message 708 is analyzed by a voice analyzer function 712, which can look for voice characteristics that indicate, for example, stress in the speaker's voice, an indication of imminent danger, or other conditions that can dictate that special alerting is used. Once analyzed, an appropriate alert (i.e. vibration pattern) is selected by alert selection function 714. The alert selected can correspond to a category of the received message, such as who it is from, whether it is work related or personal related, or a special alert type, and so on. The alert selection function 714, upon selecting an appropriate alert, forms an alert message that is provided to the transceiver 720 for transmission to the vibration alert accessory, which implements a vibration pattern in correspondence with that selected by the alert selection function 714.
Likewise, a text message 710 can be analyzed by a text analyzer 716, which can look at the source of the text message, as well as the content of the text message. Generally the source of the text message will dictate the category of the alert unless some special words or a code appear in the text massage that dictate a special alert be used. Once the text message is analyzed, an alert selection function 718 selects the appropriate vibration pattern to be used in alerting the user and forms an alert message which is provided to the transceiver 720 for transmission to the vibration alert accessory.
The administration entity 1108 can maintain a record 1122 of all alerts and individual acknowledgements received. For example, a column 1124 can correspond to the first user 1102, and a second column 1126 can correspond to the second user 1104. In each column a record can be kept of, for example, an alert being sent 1128, along with a time stamp 1130 indicating when the alert was sent. Similarly an acknowledgment entry 1134 can indicate that the user acknowledged the alert (with or without a timestamp and with or without the acknowledging user's location). In the event that user does not acknowledge an alert, the administrative entity 1108 can send a message to user's nearby the non-acknowledging user to interact with the non-acknowledging user, which can prompt the non-acknowledging user to then acknowledge the alert, or prompt those checking on the non-acknowledging user to seek assistance if, for example, the non-acknowledging user is in need of assistance.
The records 1122 can be used, in some embodiments, to reduce insurance costs. Since the organization can show alerting and acknowledgement compliance, the organization may be entitled to a discount on liability insurance. The record 1122 can also be used to show compliance with regulations, such as when the vibration alert device is disposed in a safety article (e.g. high visibility vest, hard hat/helmet, etc.), indicating, by the acknowledgements, that the users are using their safety gear in which the vibration alert accessory is disposed.
Embodiments such as those disclosed herein provide the benefit of providing tactile alerting that is more likely to be sensed by a user when, for example, wearing heaving work clothing, or in locations where there is substantial acoustic noise that would tend to mask the vibration alert of conventional communication devices. For example, heavy equipment on construction sites generate vibrations that can propagate acoustically and through the ground so as to be felt by persons in proximity to such equipment and machines. A communication device carried, for example, in a pocket, and set on “silent mode” to vibrate in response to incoming messages and calls can go undetected due to the ambient conditions masking the vibration of the communication device. A vibration alert accessory, however, can use a stronger vibration means than is found in communication devices, and can be paired with a communication device to provide high magnitude vibrations that are more likely to be sensed by the user. As such, the design goals of mobile communication devices such as small overall volume/size, and weight can be accommodated while still accomplishing alerting and notification in conditions that tend to mask the vibration/notification built into the mobile communication device. Furthermore, by analyzing incoming messages by source and content, special alerting can be used when necessary to draw users' attention dangers or other messages that require urgent attention.
In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings.
The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. The term “coupled” as used herein is defined as connected, although not necessarily directly and not necessarily mechanically. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors and field programmable gate arrays (FPGAs) and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and/or apparatus described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used.
The use of “software,” and other references to code herein, are to be construed as referring to the physical configuration of a physical media, such as, for example, electronic media (both active and passive), optical media, magnetic media, and so on, which can be read (i.e. transferred) to electronic media in a processor or other computational structure for logic operations to produce output that is also used to configure physical media and/or drive other circuitry connected to the processor, accordingly. The physical configuration of the media is specified by design to cause the processor to provide an output according to its physical design as a collection of circuitry and circuit components. As such, any reference to software or other code is not to be construed as referring to any abstract idea which generally merely describes the intended function of the actual software. It will be appreciated by those skilled in the art, however, that software can be designed in a wide variety of alternative implementations to achieve the same general functions.
An embodiment can be implemented as a computer-readable storage medium having computer readable code stored thereon for programming a computer (e.g., comprising a processor) to perform a method as described and claimed herein. Examples of such computer-readable storage mediums include, but are not limited to, a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory) and a Flash memory. Further, it is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions and programs and ICs with minimal experimentation.
The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description as part of the original disclosure, and remain so even if cancelled from the claims during prosecution of the application, with each claim standing on its own as a separately claimed subject matter. Furthermore, subject matter not shown should not be assumed to be necessarily present, and that in some instances it may become necessary to define the claims by use of negative limitations, which are supported herein by merely not showing the subject matter disclaimed in such negative limitations.
This application claims the benefit of prior U.S. provisional patent application No. 62/042,364 filed Aug. 27, 2014, the entirety of which is hereby incorporated by reference.
