The operations and functionality described here applies only to a Content Module Context.
Hardwired Controls
While listening to a content module, the content module's metadata may override the default behavior of many controls (see below), but the following features will always be accessible from within any content module (cannot be overriden/modified by content module)
Exit Content Module, back to Home Menu
Volume Control
Playback Speed Control
Navigating within a Content Module
The Hardwired Controls listed above will always be available while in any Content Module's context. In addition, the following the following actions should be available, each of which can be overriden (redirected) by the Content Module itself:
Simple Content Operations
Linear Playback within a Recording
Normal-Speed Playback
Slow-Speed Playback
Stop
User-Action Pause
Linear Navigation within a Recording
Next Track
Previous Track
Back to Beginning of Same Track
Back to Beginning of Same Recording
Jump Forward x Seconds
Jump Backward y Seconds
Fast-Speed Playback
Next Content-Embedded Index Point
Previous Content-Embedded Index Point
Prohibiting Skipping of Advertisements
Complex Content Operations
Content-Embedded Pause
Overridden Content-Embedded Pause
A continuous mode may ignore all pauses and play through from track to track. The device will still pause for any prompted interactive exercises (e.g. multiple choice questions), but the user simply hit the track fwd button to skip them.
Such a mode might be useful for people listening to the content module while working or walking (or any other activity where they are not using a book or flip chart) who want to listen to a continuous content module without hyperlinked notes (e.g. "side bars" or "foot notes"). The mode might also be useful with either literacy or information content by an intermediate reader who wants to follow the text along with the audio without pausing.
Hyperlinks
- Indication that Hyperlink is Available
- hyperlink button: usually null, but point in content track gives jump point. Light indicator is on any time hyperlink button address is not null and not automatic link
- Following a Hyperlink
- Hyperlinked Content that Returns Where it Linked From
- consider when there are multiple links to same point
- Hyperlinked Content that Returns to a Different Point in the Recording
- Hyperlinked Content that Ends the Playback
- Fitting Tap Counting into a Hyperlink Model
- Counting can be done purely with audio hyperlinks ("tap the hyperlink key for each syllable in this word"
- Playback Mode that Causes Hyperlinks to be Automatically Followed
- Automatically follow all non-prompting hyperlinks. Prompting hyperlinks (ones used for counting exercises or multiple choice questions) will still cause the device to pause for user input. The user may then just hit the track fwd button to skip the prompt.
- This mode is useful for people listening to the content module while working or walking (or any other activity where they are not using a book or flip chart) who want to listen to all of the recorded content, including hyperlinked notes.
Position-Determined Button Navigation (e.g. to enable multiple choice options)
Fitting Multiple Choice Questions into a Hyperlink Model
Applying a Meta Track to Control Action Taken in Response to User Pressing a Button
Problem: Since the difference between audio and written text is one of time and space, simply listing the multiple choices in audio and expecting the listener to remember which button corresponded to each choice might be unrealistic.
Solution: just use hyperlink button by listing the choices once and then once more with the hyperlink button keyed to answer just after choice is listed.
Alternative Solution: list choices, keys don't submit answer, but repeat option and ask to confirm by hitting the key a second time, or by hitting the confirm/hyperlink button (but this latter version wouldn't allow that key being used as one of the options). If another option key is pushed after only one tap of another, the first option is ignored and the last one is repeated and asked to confirm with another tap.
Mechanical idea:
slider switch to mechanically shift functionality of multipurpose buttons
Software idea:
Content module has track that assigns relative and absolute jumps for each of several buttons, such as:
- jump back 15 sec/jump forward 1 minute buttons (but which might jump elsewhere when used in a multiple choice question – could also be disabled, such as during advertisements)
- hyperlink button: usually null, but point in content track gives jump point. Light indicator is on any time hyperlink button address is not null
