Find and select the most appropriate interaction modality according to User environment constraints.
Lean UX Context of Use

• What hardware is used/available? • Which Interface Options come with it? • Are there any specific room situations (physical environment) (Light / Brightness, Moisture / Humidity, Noise etc.)
• Do there exist Restrictions for the user? (Gloves, environmental influences, visibility conditions etc.)
• What’s the timeframe for the interaction?
