  3. Communication Why to Model? • Highlight system properties: observability, predicatability, access points, etc. • Expose design issues: what is physical what is digital, physical syntax, expected and unexpected interactions. • Explore and compare alternative designs. • Communicate design within multidisciplinary teams • Design documentation • Guide implementation • Identify boundary cases Analysis Implementation Comp150 TUI Spring 2007

  5. Describing the Structure of a TUI using TUIML • Tokens: Physical objects that represent digital information. Users interact with tokens to access and manipulate digital information. • Constraints: Physical objects that provide context to tokens manipulation by constraining the ways in which tokens can be manipulated. A constraint constrain the manipulation of a token 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. TACs encapsulate a set of manipulation actions that can be performed upon a token in respect to a set of constraints. Comp150 TUI Spring 2007

  8. URP[Underkoffler and Ishii 1999] • A TUI for urban planning. • Combines physical building models with physical interactive tools to help urban planners perform analysis of shadows, proximities, reflection, wind and visual space. • Physical interaction objects include: • Building models • A wind tool • A material wand • A clock dial • A distance measuring tool Comp150 TUI Spring 2007

  15. Analyzing URP • Observability and predictability: • Does the physical state of the system indicate to the user the internal state of the system? • 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? • 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? Does the physical state of the system indicate to users how actions can be combined into sequences in order to perform a task? Comp150 TUI Spring 2007
