The presently disclosed technology generally pertains to systems and methods for providing alternative and augmentative (AAC) steps and features such as may be available in a speech generation device or other electronic device.
Electronic devices such as speech generation devices (SGDs) or Alternative and Augmentative Communication (AAC) devices can include a variety of features to assist with a user's communication. Such devices are becoming increasingly advantageous for use by people suffering from various debilitating physical conditions, whether resulting from disease or injuries that may prevent or inhibit an afflicted person from audibly communicating. For example, many individuals may experience speech and learning challenges as a result of pre-existing or developed conditions such as autism, ALS, cerebral palsy, stroke, brain injury and others. In addition, accidents or injuries suffered during armed combat, whether by domestic police officers or by soldiers engaged in battle zones in foreign theaters, are swelling the population of potential users. Persons lacking the ability to communicate audibly can compensate for this deficiency by the use of speech generation devices.
In general, a speech generation device may include an electronic interface with specialized software configured to permit the creation and manipulation of digital messages that can be translated into audio speech output or other outgoing communication such as a text message, phone call, e-mail or the like. Messages and other communication generated, analyzed and/or relayed via an SGD or AAC device may often include symbols and/or text alone or in some combination. In one example, messages may be composed by a user by selection of buttons, each button corresponding to a graphical user interface element composed of some combination of text and/or graphics to identify the text or language element for selection by a user.
Current advancements for speech generation devices have afforded even more integrated functionality for their users. For example, some SGDs or other AAC devices are configured not only for providing speech-based output but also for playing media files (e.g., music, video, etc.), providing access to the Internet, and/or even making telephone calls using the device.
For some of the advanced SGD functions, especially playing media files, the existing interfaces available on an SGD are fixed. Such pre-defined interfaces may typically be limited in the way they coordinate user selection and integration of the various SGD functionality. Such limitation may raise issues for users interfacing with an SGD in particular access modes, such as but not limited to eye tracking, audio scanning, or others. In addition, users do not have the option to modify such interfaces to customize various aspects thereof. This can provide potential limitations on the accessibility, efficiency, convenience and desirability of an SGD.
In light of the specialized utility of speech generation devices and related interfaces for users having various levels of potential disabilities, a need continues to exist for refinements and improvements to media player interfaces for such devices. While various implementations of speech generation devices and associated media features have been developed, no design has emerged that is known to generally encompass all of the desired characteristics hereafter presented in accordance with aspects of the subject technology.
In general, the present subject matter is directed to various exemplary speech generation devices (SGDs) or other electronic devices having improved configurations for providing selected AAC features and functions to a user. More specifically, the present subject matter provides improved features and steps for creating a customized media player interface for an electronic device.
In one exemplary embodiment, a method of providing electronic features for creating a customized media player interface for an electronic device includes a step of electronically displaying a media player interface design area to a user. A plurality of display elements are placed within the media player interface design area. In response to one or more electronic input signals from a user, selected ones of the plurality of display elements are associated with one or more electronic actions relative to the electronic initiation and control of media files accessible by the electronic device. A media player interface is then initiated on an electronic display apparatus associated with the electronic device, wherein the media player interface comprises media player features corresponding to the plurality of display elements and associated electronic actions.
In some more particular exemplary embodiments, one or more electronic input signals from a user define one or more of the number of buttons to be placed within the media player interface design area, the size of the buttons to be placed within the media player interface design area, and the relative location of the buttons within the media player interface design area. Still further, the one or more given actions relative to electronic initiation and control of media files that may be associated with selected of the plurality of display elements may comprise one or more of playing, pausing, stopping, adjusting play speed, adjusting volume, adjusting current file position, toggling modes such as repeat and shuffle, establishing a playlist, viewing a playlist, modifying a playlist, clearing a playlist. Display elements also may be associated with one or more given electronic actions relative to the communication of speech-generated message output provided by the electronic device.
In other more particular exemplary embodiments, labels also may be associated with selected ones of the plurality of display elements. Selected labels may correspond to one or more of symbols and text describing the actions associated with each display element. Selected labels may correspond to media status labels that identify certain aspects of media file action status, including one or more of a current media file label, current playlist label, media playing status, media shuffle status, and media repeat status.
In still other more particular exemplary embodiments, electronic input signals may define how to configure the electronic device for playing the audio portion of media files when other audio signals are also provided as output, how to configure the electronic device for editing existing playlist files when new files are added to an existing playlist, and/or specific levels for volume settings associated with the playback of speech signals, audio feedback signals, and media signals.
It should be appreciated that still further exemplary embodiments of the subject technology concern hardware and software features of an electronic device configured to perform various steps as outlined above. For example, one exemplary embodiment concerns a computer readable medium embodying computer readable and executable instructions configured to control a processing device to implement the various steps described above or other combinations of steps as described herein.

Thus, it is intended that the presently disclosed technology cover such modifications and variations as may be practiced by one of ordinary skill in the art after evaluating the present disclosure. The same numerals are assigned to the same or similar components throughout the drawings and description.
The technology discussed herein makes reference to processors, servers, memories, databases, software applications, and/or other computer-based systems, as well as actions taken and information sent to and from such systems. The various computer systems discussed herein are not limited to any particular hardware architecture or configuration. Embodiments of the methods and systems set forth herein may be implemented by one or more general-purpose or customized computing devices adapted in any suitable manner to provide desired functionality. The device(s) may be adapted to provide additional functionality, either complementary or unrelated to the present subject matter. For instance, one or more computing devices may be adapted to provide desired functionality by accessing software instructions rendered in a computer-readable form. When software is used, any suitable programming, scripting, or other type of language or combinations of languages may be used to implement the teachings contained herein. However, software need not be used exclusively, or at all. For example, as will be understood by those of ordinary skill in the art without required additional detailed discussion, some embodiments of the methods and systems set forth and disclosed herein also may be implemented by hard-wired logic or other circuitry, including, but not limited to application-specific circuits.

Referring now to the drawings, various aspects of a system and method of providing electronic features for creating a customized media player interface for an electronic device are disclosed. In general, the subject technology provides features by which a user can create a media player interface (e.g., an MP3 player or interface to play other music, video, picture or other media files). Instead of being limited to a pre-defined media player interface as available in known devices, features for providing a custom interface allow users to incorporate whatever buttons, symbols, sizes, colors, language, labels, related actions or other functionality or features desired for initiating and controlling media files accessible by an electronic device. By delivering complete control of a media player interface design, electronic devices such as speech generation devices can become more functionally adaptable for users implementing a variety of different access methods (e.g., touch screen, joystick, mouse pause, eye tracking, and the like).
The ability to accommodate customized designs for media playing functionality in user interfaces for an electronic device provides a variety of advantages. For example, interfaces can be created having arbitrarily sized buttons and collections of functions to accommodate user preferences and access abilities. Media playing buttons and associated functionality can also be integrated with other basic functionality of a speech generation device, such as buttons for generating, relaying and/or otherwise coordinating the communication of speech-generated message outputs provided by a device. In addition, a variety of media action functions can be integrated in custom arrangements. Examples of actions that may be linked to various display elements in a custom interface include playing, pausing, stopping, adjusting play speed, adjusting volume, adjusting current file position, toggling modes such as repeat and shuffle, establishing a playlist, viewing a playlist, modifying a playlist, clearing a playlist, etc.
The steps shown in
A first exemplary step 102 is to electronically display to a user of an electronic device a graphical user interface design area having a plurality of display elements placed therein. The graphical user interface design area (i.e., the media player interface design area) is the basic framework in which a user can design and customize a media player interface. As such, at least some of the display elements within such interface design area are customizable by a user by selecting various actions and labels to accompany such display elements. The basic framework of the graphical user interface design area (e.g., the size and shape of the interface, the number of display elements, the size and shape of the display elements and placement location within the interface) may be either pre-defined or customized by a user. When one or more of such aspects are pre-defined, they may be part of an existing interface having open room for customizable buttons or other display elements. Alternatively, it is possible in one embodiment for a user to create from scratch every aspect of a custom media interface, including the basic framework associated with the interface design area and display elements.
Referring again to
A variety of different actions may be associated with the display elements as defined by a user in step 104. For example, at least one of the display elements in accordance with aspects of the presently disclosed technology is configured to initiate and/or control media files (e.g., music, video, graphics or the like) accessible by the electronic device. Media initiation and control actions include but are not limited to playing, pausing, stopping, adjusting play speed, adjusting volume, adjusting current file position, toggling modes such as repeat and shuffle, establishing a playlist, viewing a playlist, modifying a playlist, clearing a playlist. Specific details regarding the above actions and others that may be associated with display elements for a media player interface are presented in Table 1 below.
The display elements within a graphical user interface design area also may be linked to actions related to the communication of a composed message as “spoken” audio output, or relay as a text message, phone call, e-mail or other outgoing communication. Exemplary linked actions in accordance with such basic functionality of a speech generation device include one or more of speaking a message (i.e., making the button speak the message entered by a user using a synthesized computer voice, recorded voice or combination of sounds), typing a message (i.e., placing a message entered by the user into the message display), reading with highlighting (i.e., reading and highlighting the symbols and text on the face of a symbolate button), playing a recorded message (i.e., playing a message recorded by a user or a selected saved sound), changing a board to a new selected board or to a previously selected board, providing a text preview (i.e., displaying a text cue for the button's function when a pointer is placed over the button), providing a spoken preview (i.e., playing a synthesized voice cue for the button's function when a pointer is placed over the button), providing a recorded preview (i.e., playing a recorded cue for the button's function when a pointer is placed over the button), clearing the contents of the message display if a message display is present on the board, and/or providing a picture button (i.e., placing the symbol and/or graphic on the face of a button into the message display if a message display is present on the board). A user may implement such actions as making a button play a recorded message, giving a button a spoken preview, adding a preview display, editing a button's assigned actions, making a button speak, making a button play a saved sound, giving a button a recorded preview, and/or changing a button's text preview.

Another example of labels that may be associated with selected display elements in a media player interface correspond to media status labels. In general, media status labels correspond to display elements that have associated labels but not associated actions, wherein the labels are used to visually represent certain aspects of the status of current media file action in a media player. For example, exemplary media file action status options may include, but are not limited to, a current media file label (e.g., Current Song—displays the filename of the song or other media file that is currently being played or is paused), current playlist label (e.g., Current Playlist—displays the current playlist, with the song name currently playing/paused in a different color than other songs or media elements on the playlist), media playing status (e.g., Music Playing Status—displays the status of the current song—“playing,” “paused,” or “stopped” or associated symbols/icons), media shuffle status (e.g., Music Shuffle Status—displays the current state of the shuffle feature—“shuffle on” or “shuffle off” or associated symbols/icons), and media repeat status (e.g., Music Repeat Status—displays the current state of the repeat feature—“repeat one,” “repeat all,” or “repeat none.”)
Another example of media status labels corresponds to icons that may be placed in an interface (e.g., on a portion of a title bar or other designated location) that appear to provide an indication to a user of the status of the music file that is currently playing on the electronic device. For example, title bar music icons may include selected combinations of one or more of the following examples: a play icon to indicate that the song is currently playing, a pause icon to indicate that the song is currently paused, a fast forward icon to indicate that the song is advancing at a speed rate faster than the regular playing speed, a rewind icon to indicate that the song is moving backwards at a speed faster than the regular playing speed, a shuffle icon to indicate that the song(s) in the playlist will be played in random order, a repeat one song icon to indicate that the current song will be repeated, and a repeat playlist icon to indicate that the entire playlist will be repeated.

In more specific examples, electronic device 500 may correspond to a stand-alone computer terminal such as a desktop computer, a laptop computer, a netbook computer, a palmtop computer, a speech generation device (SGD) or alternative and augmentative communication (AAC) device, such as but not limited to a device such as offered for sale by DynaVox Mayer-Johnson of Pittsburgh, Pa. including but not limited to the V, Vmax, Xpress, Tango, M3 and/or DynaWrite products, a mobile computing device, a handheld computer, a tablet computer (e.g., Apple's iPad tablet), a mobile phone, a cellular phone, a VoIP phone, a smart phone, a personal digital assistant (PDA), a BLACKBERRY™ device, a TREO™, an iPhone™, an iPod Touch™, a media player, a navigation device, an e-mail device, a game console or other portable electronic device, a combination of any two or more of the above or other electronic devices, or any other suitable component adapted with the features and functionality disclosed herein.
When electronic device 500 corresponds to a speech generation device, the electronic components of device 500 enable the device to transmit and receive messages to assist a user in communicating with others. For example, electronic device 500 may correspond to a particular special-purpose electronic device that permits a user to communicate with others by producing digitized or synthesized speech based on configured messages. Such messages may be preconfigured and/or selected and/or composed by a user within a message window provided as part of the speech generation device user interface. As will be described in more detail below, a variety of physical input devices and software interface features may be provided to facilitate the capture of user input to define what information should be displayed in a message window and ultimately communicated to others as spoken output, text message, phone call, e-mail or other outgoing communication.
Referring more particularly to the exemplary hardware shown in
At least one memory/media device (e.g., device 504a in
The various memory/media devices of
In one particular embodiment of the present subject matter, memory/media device 504b is configured to store input data received from a user, such as but not limited to data defining a media player interface design area (e.g., size of interface and number, size and/or shape of display elements therein), data defining the one or more actions associated with selected display elements, data defining the one or more action identification labels or media status labels associated with selected display elements, etc. Such input data may be received from one or more integrated or peripheral input devices 510 associated with electronic device 500, including but not limited to a keyboard, joystick, switch, touch screen, microphone, eye tracker, camera, or other device. Memory device 504a includes computer-executable software instructions that can be read and executed by processor(s) 502 to act on the data stored in memory/media device 504b to create new output data (e.g., audio signals, display signals, RF communication signals and the like) for temporary or permanent storage in memory, e.g., in memory/media device 504c. Such output data may be communicated to integrated and/or peripheral output devices, such as a monitor or other display device, or as control signals to still further components.
Referring still to
Various input devices may be part of electronic device 500 and thus coupled to the computing device 501. For example, a touch screen 506 may be provided to capture user inputs directed to a display location by a user hand or stylus. A microphone 508, for example a surface mount CMOS/MEMS silicon-based microphone or others, may be provided to capture user audio inputs. Other exemplary input devices (e.g., peripheral device 510) may include but are not limited to a peripheral keyboard, peripheral touch-screen monitor, peripheral microphone, mouse and the like. A camera 519, such as but not limited to an optical sensor, e.g., a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, or other device can be utilized to facilitate camera functions, such as recording photographs and video clips, and as such may function as another input device. Hardware components of SGD 500 also may include one or more integrated output devices, such as but not limited to display 512 and/or speakers 514.
Display device 512 may correspond to one or more substrates outfitted for providing images to a user. Display device 512 may employ one or more of liquid crystal display (LCD) technology, light emitting polymer display (LPD) technology, light emitting diode (LED), organic light emitting diode (OLED) and/or transparent organic light emitting diode (TOLED) or some other display technology. Additional details regarding OLED and/or TOLED displays for use in SGD 500 are disclosed in U.S. Provisional Patent Application No. 61/250,274 filed Oct. 9, 2009 and entitled “Speech Generation Device with OLED Display,” which is hereby incorporated herein by reference in its entirety for all purposes.
In one exemplary embodiment, a display device 512 and touch screen 506 are integrated together as a touch-sensitive display that implements one or more of the above-referenced display technologies (e.g., LCD, LPD, LED, OLED, TOLED, etc.) or others. The touch sensitive display can be sensitive to haptic and/or tactile contact with a user. A touch sensitive display that is a capacitive touch screen may provide such advantages as overall thinness and light weight. In addition, a capacitive touch panel requires no activation force but only a slight contact, which is an advantage for a user who may have motor control limitations. Capacitive touch screens also accommodate multi-touch applications (i.e., a set of interaction techniques which allow a user to control graphical applications with several fingers) as well as scrolling. In some implementations, a touch-sensitive display can comprise a multi-touch-sensitive display. A multi-touch-sensitive display can, for example, process multiple simultaneous touch points, including processing data related to the pressure, degree, and/or position of each touch point. Such processing facilitates gestures and interactions with multiple fingers, chording, and other interactions. Other touch-sensitive display technologies also can be used, e.g., a display in which contact is made using a stylus or other pointing device. Some examples of multi-touch-sensitive display technology are described in U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), U.S. Pat. No. 6,677,932 (Westerman), and U.S. Pat. No. 6,888,536 (Westerman et al.), each of which is incorporated by reference herein in its entirety for all purposes.
Speakers 514 may generally correspond to any compact high power audio output device. Speakers 514 may function as an audible interface for the speech generation device when computer processor(s) 502 utilize text-to-speech functionality. Speakers can be used to speak the messages composed in a message window as described herein as well as to provide audio output for telephone calls, speaking e-mails, reading e-books, and other functions. Speech output may be generated in accordance with one or more preconfigured text-to-speech generation tools in male or female and adult or child voices, such as but not limited to such products as offered for sale by Cepstral, HQ Voices offered by Acapela, Flexvoice offered by Mindmaker, DECtalk offered by Fonix, Loquendo products, VoiceText offered by NeoSpeech, products by AT&T's Natural Voices offered by Wizzard, Microsoft Voices, digitized voice (digitally recorded voice clips) or others. A volume control module 522 may be controlled by one or more scrolling switches or touch-screen buttons.
The various input, output and/or peripheral devices incorporated with SGD 500 may work together to provide one or more access modes or methods of interfacing with the SGD. In a “Touch Enter” access method, selection is made upon contact with the touch screen, with highlight and bold options to visually indicate selection. In a “Touch Exit” method, selection is made upon release as a user moves from selection to selection by dragging a finger as a stylus across the screen. In a “Touch Auto Zoom” method, a portion of the screen that was selected is automatically enlarged for better visual recognition by a user. In a “Scanning” mode, highlighting is used in a specific pattern so that individuals can use a switch (or other device) to make a selection when the desired object is highlighted. Selection can be made with a variety of customization options such as a 1-switch autoscan, 2-switch directed scan, 2-switch directed scan, 1-switch directed scan with dwell, inverse scanning, and auditory scanning. In a “Joystick” mode, selection is made with a button on the joystick, which is used as a pointer and moved around the touch screen. Users can receive audio feedback while navigating with the joystick. In an “Auditory Touch” mode, the speed of directed selection is combined with auditory cues used in the “Scanning” mode. In the “Mouse Pause/Headtrackers” mode, selection is made by pausing on an object for a specified amount of time with a computer mouse or track ball that moves the cursor on the touch screen. An external switch exists for individuals who have the physical ability to direct a cursor with a mouse, but cannot press down on the mouse button to make selections. A “Morse Code” option is used to support one or two switches with visual and audio feedback. In “Eye Tracking” modes, selections are made simply by gazing at the device screen when outfitted with eye controller features and implementing selection based on dwell time, eye blinking or external switch activation.

When different wireless communication devices are included within an SGD, a dedicated communications interface module 520 may be provided within central computing device 501 to provide a software interface from the processing components of computer 501 to the communication device(s). In one embodiment, communications interface module 520 includes computer instructions stored on a computer-readable medium as previously described that instruct the communications devices how to send and receive communicated wireless or data signals. In one example, additional executable instructions stored in memory associated with central computing device 501 provide a web browser to serve as a graphical user interface for interacting with the Internet or other network. For example, software instructions may be provided to call preconfigured web browsers such as Microsoft® Internet Explorer or Firefox® internet browser available from Mozilla software.
Antenna 515 may be provided to facilitate wireless communications with other devices in accordance with one or more wireless communications protocols, including but not limited to BLUETOOTH, WI-FI (802.11 b/g), MiFi and ZIGBEE wireless communication protocols. In general, the wireless interface afforded by antenna 515 may couple the device 500 to any output device to communicate audio signals, text signals (e.g., as may be part of a text, e-mail, SMS or other text-based communication message) or other electronic signals. In one example, the antenna 515 enables a user to use the device 500 with a Bluetooth headset for making phone calls or otherwise providing audio input to the SGD. In another example, antenna 515 may provide an interface between device 500 and a powered speaker or other peripheral device that is physically separated from device 500. The device 500 also can generate Bluetooth radio signals that can be used to control a desktop computer, which appears on the device's display as a mouse and keyboard. Another option afforded by Bluetooth communications features involves the benefits of a Bluetooth audio pathway. Many users utilize an option of auditory scanning to operate their device. A user can choose to use a Bluetooth-enabled headphone to listen to the scanning, thus affording a more private listening environment that eliminates or reduces potential disturbance in a classroom environment without public broadcasting of a user's communications. A Bluetooth (or other wirelessly configured headset) can provide advantages over traditional wired headsets, again by overcoming the cumbersome nature of the traditional headsets and their associated wires.
When an exemplary SGD embodiment includes an integrated cell phone, a user is able to send and receive wireless phone calls and text messages. The cell phone component 516 shown in
