Help

Welcome message

The welcome message is a permanent system message for the device that is played whenever the home context is reached. The message itself consists of:

  • A short 1-2 second sequence of tones that uniquely identifies Literacy Bridge device and its home context, without having to listen to the spoken words recorded. The short sequence of tones should serve two purpose:
    • First the tone allows the operator to feel a sense of familiarity and security, that whenever they hear the tone, that they are at the home context and they know what to expect next. The home context is designed specifically to create a sense of familiarity, that no matter what "mistakes" the user did in operating the device, they can always go back to the bedrock that is home. We would like to create this sense of security not only in spoken words in the local language, but to do it musically and in a short span of 1-2 second, so the user can pick it up without intent listening to the words.
    • Second, the tone will serve as the audio branding element of the Talking Book, as unique as the orange oval industrial design of the device itself. Think the Intel Inside sequence of tones. Whenever the notes are heard in the village or town, the reaction should be "ah, someone nearby is using the Talking Book," which hopefully is followed by "I want to get one so I too can learn to read and write."
  • The tones are followed by the localized name of the Talking Book, which should be as short and simple to remember as possible.
  • SAF for "Tap the Home/Help key to hear how to operate the device"

General Help Content

From the Welcome message and Home context, if the help key is tapped, A full audio recording of the device's instruction is played. The instructions are always spoken words in the local language in which the device is distributed.

The sequence of help topics is as follows (in order):

  • how to get back to the home context
  • how to get help at any time
  • how to change volume
  • how to select a content module
  • how to play and stop
  • how to jump backwards 15 sec and forward 60 sec. while listening
  • how to navigate and jump to previous/next module
  • how to change playing speed
  • how to operate hyperlink (play examples of the hyperlink tone)
  • how to copy material from one device to another

Help at Any Time

Help can be obtained at any time by tapping the home/help button:

  • Tapping it will bring up context-sensitive help, i.e. brings up the most relevant help module to the current context.
  • Holding it will bring the user all the way back to the home context.

When inside of help context the user can always return to his previous context by tapping Help button again.

When playing and listening to content, tapping help will announce the following, in order:

  • SAF for "Help" in the local language
  • "You are listening to <title of the current module>" in the local language
  • "You can get back to listening by tapping Help/Home button again"
  • If the module itself has specialized help content:
    • Play the hyperlink tone
    • "This module has special help instruction, tap the <hyperlink> key to hear it"
    • If the hyperlink key is tapped, play the special module-specific help content
    • While listening to the module-specific help, the user can escape back to the general help by tapping the help key, in which case it restarts the whole sequence at the top
  • Play the General Help Content as listed in the section above

Since Playing and Navigating is the most common scenario, the device allows the user to escape the help context and get back to listening by tapping Play/Pause, picking up where he/she left off. Note that any "content stack" due to hyperlinking activities are preserved.

There are other ways to "undo" help as well:
* When selecting content, the use can hit any of the directional keys to get back to content selection. When resuming, the appropriate SAF for content selection will be played to give users a reminder of where they left off
* When changing playback speed, the user can get back by using UP or DOWN or PLAY. When resuming, the appropriate SAF for speed control will be played to give users a reminder of where they left off
* When doing device-to-device copy…blah…blah…blah…

Issues:

  • Can we allow interactive exercises in the help module, so the users can try out the instructions right inside help? Some of the keys would already be programmable by a content module, but the main ones like Play, etc. are not.
