3. ConcurTaskTrees Task model of a user sending an e-mail

4. Repeating Sub-Trees

5. Interaction Templates Model complex interface interactions commonly found in information systems Parameterized CTT subtrees  Inserted into large task models  Customizable Through parameters, or By hand

6. Defining Interaction Templates Compact description of a CTT that can be customized through a set of parameters Interaction Template Definition Language  XML CTT description  Embedded template statements

7. Defining Interaction Templates XML CTT Description … … …

8. Defining Interaction Templates Defining a template and its options … Option types include  String, Integer, Boolean, and XML Files

9. Defining Interaction Templates it:case chooses the first it:condition whose expression evaluates to true Defining a template and its options … … …

10. Defining Interaction Templates it:foreach loops through each possible value for its single attribute Defining a template and its options … … …

11. Template Attributes/Elements $attribName is replaced with a value  Attribute value or  XML element Sub elements and attributes can also be referenced (eg. $schema.element.name)

12. Simulating Task Models Calculate Enabled Task Sets Calculate Initial State Calculate State Transition Network

13. Simulating Interaction Templates Interaction Templates can be simulated using concrete user interface components =

14. Simulating Interaction Templates Enhanced Task Model Simulator takes in XML CTT description and ETS/STN Establishes a socket connection with all Interaction Template prototypes

15. Perform Task Simulating Interaction Templates When an Interaction Template is reached in simulation, a message is sent to the prototype Enhanced Task Model Simulator Interaction Template Prototype Interaction Template Prototype Interaction Template Prototype Enable Disable

16. Generating Prototypes TfrmPrototype contains  Basic functionality common to all prototypes (communication with simulator)  Specific adaptations based on it:options TfrmPrototypeTfrmDataTable Inherits From

17. Enhanced Task Model Simulator

18. Conclusions Interaction Template Definition Language  Define templates through annotations? Enhanced Task Model Simulator  Simulate Interaction Templates using concrete user interface components  Currently, prototypes are manually built Adapt to the options set in the template
