User Stories

Roughing out the scope here before messing with Jira (less work).

Fridays will come fast. In order to deliver on such a sort timeline, we must avoid gold plating. The team should strive to provide a “barely sufficient” solution to each story. This will help ensure we have something to demo every week. The fidelity of a given feature can be improved through additional stories as time permits. There can always be another story.

Display

• Clinician can display a shelf containing 5 instruments
  • display a shelf that matches real one used by clinician (mostly done)
• Clinician can configure what instruments appear on the shelf
  • fixed set of 5 instruments
  • choose location on shelf
  • hide/show instruments

P300 selection

• Clinician can train the BCI
  • classifier is calibrated during trials
  • run 5 trials to train the BCI (yes, we want to pause later, but not yet)
• Clinician can start a selection session (flashing instruments)
  • pressing a key (may not want a button on the screen for this)
  • flashing happens for a fixed timeout
• Clinician can stop a selection session
  • if clinician wants to abort the timeout, they can
• Child can select an instrument on the shelf by staring at it
  • selection happens via P300
• Child can trigger an audio request by selecting an instrument
  • on selection, an audio clip is played requesting the object, ex: “I want the maracas”
• Clinician can train the BCI in through many single trials
  • clinician can pause between trials so they can grab instrument, etc.
  • clinician can trigger next trial

Refinements (nice to have)

• Clinician can easily hide/show objects on shelf during session
  • (not sure if this was needed or not)
• Clinician can select instruments from a larger set
  • Provide a library of instruments to choose from
  • Each instruments comes with an associated audio clip
• Clinician can add new instruments
  • Add a 3D model to library
  • Associate with audio clip
• Clinician can adjust the P300 stimulus component
  • this could just be raw Unity editor changes? potentially hard coded
• Clinician can choose a P300 set of stimulus components
  • choosing a set from a list (ex: combination of color, size)
• Clinician can start application easily
  • Unity starts up in the game mode
  • Bessy utilities automatically start up and receive EEG data from headset
• Clinician can save a profile for a given Child
  • shelf appearance
  • save instruments, visibility, location
  • save P300 stimulus components
  • (unity may have an easy canned way to handle this)
• Clinician can start session by choosing a profile
  • this sets up the shelf / instruments / flashing style
