Communication Why to Model? • Highlight system properties: observability, predicatability, modes etc. • Expose design issues • Compare alternative designs. • Communicate design to SW engineers • Communicate design to ‘customers’ • Design documentation • Generate code from technology independent spec. • Integrate novel technologies Analysis Implementation Comp150 TUI Spring 2006
A Framework for modeling TUIsToken and Constraints (TAC) Paradigm • Tokens: Physical objects that represent digital information • Constraints: Physical objects that constraint the manipulation of tokens by: • Suggesting how to manipulate a token • Physically constraining • Providing a frame of reference • TAC: A relationship between a token and a set of constraints which encapsulates a set of manipulation actions Comp150 TUI Spring 2006

Constructing the Dialogue Diagram • What is the initial state of the system? • What tasks are users willing to accomplish while interacting with the URP interface? • Start from the start state and repeat until you can’t find new states: • What event change the set of tasks users can perform in this state? • Create a new state, describe the new set of tasks.

Constructing a Task Diagram • What is the physical state of the system prior to the first action aimed at accomplishing this task? • What are the actions users perform toward accomplishing this task? • What physical interaction objects are needed for each action? • What is the physical state of the system after an action was performed? • What is the internal state of the system after an action was performed? • When does the system physical state goes back to its state prior to the execution of the first action?

Project 1, Part 2Analyzing TUIs • What to submit: • A TAC Palette • A dialogue diagram • At least two task diagrams • Discussion of the following topics: • Observability and predictability: • Does the physical state of the system indicate to the user the internal state of the system? Is there information in the internal state that is not presented in the physical state? • Does the physical state of the system contain enough information to enable the user to determine what tasks are available for him to perform? Assuming multiple users interact with the system at the same time. Does the physical state of the system indicate to users what tasks they can or cannot perform in parallel? If possible bring an example of two tasks that different users cannot perform in parallel. • Modes • Certain actions are meaningful only in certain contexts. Bring an example of a user action that is meaningless in one context and has a meaning in another. • Physical Syntax • Does the physical state of the system indicate to users which actions are legal/illegal?
