Limitations and Hard-coded features

Limitations/tradeoffs of the current prototype

• Animations are not in the current prototype.
• By now, we could only send notifications, and could not trigger an alarm.
• FAQ and Feedback page in the Settings Page is not yet implemented

Wizard of Oz techniques

• The machine status is simulated.
  • It’s computed with the state transition here: Machine state simulation
  • For demonstration, the time in the app is speeded by 60x (1 second = 1 minutes).
• The e-payment does not direct the users to a 3-rd party payment app
  • Reason: we do not register with 3-rd party payment services to receive payment.

Hard-coded features

The data of all dormitories and floors are hard-coded.
