Initial research

• Contextual Inquiry in the video rental context
  
  
• Observations of people renting videos
  
  
• Surveys of people's renting habits
  
  
• Literature reviews of people's movie renting behavior and how they search through large sets of data
  
  
• Evaluations of current video information systems, both kiosks and the Internet Movie Database http://imdb.com
  
  
• Research provided valuable data that determined the starting point for the prototype

Iterative development

• Added new features and refined the prototype weekly
  
  
• Found usability problems with 5 user tests per week
  
  
• Total of 51 users in the ten weeks of iterations

Prototype fidelity

• First prototypes were low fidelity paper prototypes focusing on single features
  
  
• Tested general navigation structure using paper prototypes and PowerPoint
  
  
• Director prototypes tested more comprehensive navigation, animation and quicktime
  
  
• Final prototype with Java included a full database of movies, a large selection of trailers, a complete visual interface and a touch-screen
