Assignment 10

Design a new user interface for thermostat; create 3 UI options.

To begin, create a diagram of a home HVAC system

- What are the physical components of the system? (artifacts, stocks, + flows)

- What are the information elements of the system? (information + feedback)

Create a “user conceptual model” of a thermostat that controls the system.

Create a mock-up of the displays and controls (what users see + change).

Specify how users will interact with the thermostat.
