TUI Examples Review

• Pros
• RFID tag data
• RFID tag commands
• Single function
• Familiar use

• Cons
• Static assignment
• Limited vocabulary
• Non-standard environment
• Only TUI

RFID cards can be integrated as an alternative,
general purpose interface to provide dynamic
semantics and rich interactions.
