Initiating Interaction

• Discoverability challenge

  - Difficulty for users to find and execute available functions in a user interface
  - The invisibility and ephemerality of speech exacerbate this challenge with voice interfaces

• Performance in the requested strategy varied
• Adopt explicit prompts for new devices, voices or periodically to encourage experimentation
• Ease off to explicit requests after initial use
