  • discovery steps(5~10s)
    
• IrDA
• the immediateness of the connection, low cost

Case study

• Marble museum, Carrara, Italy.
• human guides are too expensive
• Design is driven by three main element
  
• Context of use
• JPEG, MP3
  
• SD card
  
• Tasks
• orientation with in the museum
• controlling the user interface
• access museum information
  
• Domain concept and user interface
• The museum
• The section
• Artworks
  

Location-dependent interaction

• IR installed at the entrance of each room
• located on the top the ceiling
• IR beacons send a unique identifier
• App detect and change
• Visual feedback
• Audio feedback
• error, alert and information message

Design criteria for graphical part

• A web metaphor
• Navigation feedback(by color)
• Orientation support in surrounding environment
• Minimize graphical interaction(vocal)
• No redundancy in input commands(resoluation)
