  • Page 3: General Information

    30 minutes of inactivity. There are two models of the digital-talking book player, the Standard Model (DS1) and the Advanced Model (DA1). Features Common to Both Models The Rewind, Play/Stop, and Fast Forward controls are centered and located close to the front edge of the player.
  • Page 4 General Information Section 1 The square, green Play/Stop button initiates the playing of a book or stops a book or message already playing. Holding this button down on the Standard Player enters and exits the built-in User Guide. The white, triangular Rewind and Fast Forward buttons to the left and right of the Play/Stop button move the reading position through the book, further in time and book structure the longer the button is held down.

  • Page 5: Advanced Features

    General Information Section 1 The cartridge used with the player is about the size of a compact cassette, but with a more complex shape. The end of the cartridge with the round finger hole is beveled, so that when that end of the cartridge is pressed down on a flat surface in front of the player, the other end of the cartridge, with the USB Connector, tilts up and can slide smoothly into the player.
  • Page 6 General Information Section 1 The white, diamond-shaped Information button near the left edge of the player is used to obtain information about the reading position, the book currently being read, and the power and battery status of the player. The white, rectangular Bookmark button near the right edge is used to insert and delete bookmarks. Once a bookmark is set, the reading position may be returned to the bookmark by using the Previous and Next buttons provided the bookmark navigation level has been selected with the Menu button.
  • Page 7 General Information Section 1 It is estimated that the battery pack will have a service life in excess of 600 charge cycles. Under moderate battery usage (4 hours per day for 5 days per week), the battery life should exceed 4 years. At the end of its service life the capacity of the battery pack will be 75 percent of its initial value.

  • Page 11: Digital Talking Book

    General Information Section 1 Digital Talking Book A digital talking book is composed of a collection of computer files. These files contain the digitized audio content along with information on the book’s structure to permit both random access and linear reading of the material. To play the book, a compatible player requires information on how all the audio files fit together and the location of the book structure elements such as parts, chapters, and optionally page numbers.
  • Page 12 General Information Section 1 1.4.1.2 Navigation Control File The Navigation Control file (NCX) exposes the hierarchical structure of a DTB to allow the user to navigate through it. The NCX is similar to a table of contents in that it enables the reader to jump directly to any of the major structural elements of the document, i.e., part, chapter, or section.
  • Page 13 General Information Section 1 SMIL file where the chapter begins. The NCX file will also have a direct pointer to the audio clip that will render the name of the chapter so that the user can quickly locate the navigation point of interest. Both the standard and advanced players use information in the NCX file to report the book title and reading position location.

  • Page 14: User Operation And Controls

    User Operation and Controls Section 2 User Operation and Controls The player responds to user actions by a combination of two processes. The first moves or stops moving the reading position (referred to as navigation) and the second initiates or alters the characteristics (volume, tone, or speed) of the audio rendered by the player.
  • Page 15 User Operation and Controls Section 2 Play/Stop Primary Pressing the Play/Stop button while the player is stopped starts or resumes playback of the book. Playback resumes from the reading position noted by the player for the current book when playback or navigation last ended. Pressing the Play/Stop button while the player is playing a book or message stops playback and silences the player.
  • Page 16 User Operation and Controls Section 2 Rewind Rewind and Fast Forward are the principal means of book navigation for the Standard Model player. The rewind and fast forward behavior of the Standard and Advanced Models are the same; however, users of the Advanced Model will most likely use its other controls to perform most navigation.
  • Page 17 User Operation and Controls Section 2 Fast Forward Pressing and releasing the Fast Forward (FF) button moves the reading position forward 5 seconds. Pressing and holding the Fast Forward button moves the reading position forward at an accelerating rate. When a chapter boundary is crossed, a beep is heard. Releasing the Fast Forward (FF) button immediately following a beep will snap the reading position to the beginning of the chapter.
  • Page 18 User Operation and Controls Section 2 Volume Pressing the Volume Up or Volume Down button adjusts the audio volume. Each press of the control will make one adjustment. There is a total of 45 dB of volume control in 15 steps.
  • Page 19 User Operation and Controls Section 2 Speed The speed of playback is adjustable using the Speed Up and Speed Down buttons. The speed is adjustable from one half to three times normal. That is to say if a book took a narrator 7 hours to narrate, it would take 2 hours and 20 minutes to render at the fastest setting.
  • Page 20 User Operation and Controls Section 2 Controls Exclusive to the Advanced Model (DA1) Information Primary Pressing the Information (Info) button gives information on the book and on the player state. Information given for an ANSI/NISO book: 1. Current position in the book (i.e., chapter) 2.
  • Page 21 User Operation and Controls Section 2 Previous Primary Pressing the Previous (Prev) element button moves the reading position to the beginning of the previous navigation element at the hierarchical level selected by the Menu button (chapter, section, page, bookmark, etc.) The player reacts differently depending on the current navigation level and whether the player is playing the book prior to the Previous element action: Navigation level...
  • Page 22 User Operation and Controls Section 2 Next Primary Pressing the Next element button moves the reading position to the beginning of the next navigation element at the hierarchical level selected by the Menu button (e.g., chapter, section, page, bookmark, etc.) The player reacts differently depending on the current navigation level and whether the player is playing the book prior to the Next element action: Navigation level...

  • Page 23: Player Controls Using Assistive Technology Devices

    User Operation and Controls Section 2 Bookmark Pressing the Bookmark (Mark) button will insert a bookmark at the current reading position.

If not playing, the reading position must be Mark exactly at the existing bookmark to remove it.
  • Page 24 User Operation and Controls Section 2 2.2.2 AT Device Learning Mode The player can be instructed as to which controls on the AT device are to operate particular player functions. This assignment is performed through a learning process. Entering AT Device Learning Mode Press and hold for 5 Connect the AT device to the USB port on the side of the player.
  • Page 25 User Operation and Controls Section 2 2.2.3 USB Joystick Patrons with physical disabilities may find it simpler to move a joystick than to press a button. The two-axis (x,y) USB joystick of a gamepad can be used to control the player. Movements of the joystick to the top-left, top-center, top-right, left, right, bottom-left, bottom-center, and bottom-right positions can be assigned to player controls using the learning mode.
