Fig 2&#039;s example of circuits is a relatively simple one. [[User:Syan055|Syan055]]<br /> * (From the looks of it) two-dimensional, would need a three-dimensional workspace for some applications that require more than just stacking agents in the same cell. [[User:Syan055|Syan055]]<br /> * With gui designing tools galore, it may as well pay off to just program something directly in other high-level languages IF the tailoring process is highly sophisticated.<br /> * Adjacency could imply non-existent relationships between components <br /> * Could be over-generalized.<br /> * Can get messy for highly asynchronous illustrations<br /> * Based on Lisp - not as common as other languages like Java, C, C++ etc<br /> <br /> === Cognitive dimensions === [[User:zshe004|zshe004]]<br /> <br /> * 1. gradient: yes, abstraction can be made - (level low, manually),<br /> * 2. closeness of mapping: easy<br /> * 3. diffuseness: very easy, user can define<br /> * 4. error-proneness: low, the spatial and temporal metaphors are clear<br /> * 5. hard mental operations: low, relatively easy<br /> * 6. hidden dependencies: low, clear<br /> * 7. premature commitment: no<br /> * 8. progressive evaluation: yes, can do<br /> * 9. role-expressivemess: yes<br /> * 10. secondary notation: yse<br /> * 11. viscosity: low to moderate<br /> * 12. visibility: yes.<br /> * 13. availability: low, platform restriction: only on Machintosh and SPARC Station<br /> <br /> === Other Literature ===<br /> * [http://jasss.soc.surrey.ac.uk/3/3/forum/1.html AgentSheets: End-User Programmable Simulations] [[User:Zlee003|Zlee003]]<br /> * [15] in biblio! [[Image:Repenning-PhD.pdf]][[User:Syan055|Syan055]]<br /> * [14] in biblio! [[Image:Creating_User_interfaces_with_agentsheets.pdf]]<br /> <br /> == Presentation ==<br /> * [https://www.se.auckland.ac.nz/research/projects/softeng401.2007/066/Tools/PHP/AutoIndex/index_icons/apache/Agentsheets.ppt Download the presentation]<br /> <br /> === Presenter ===<br /> * Daniel<br /> <br /> === Domain ===<br /> * Domain-independent<br /> * Style of abstraction<br /> To Do: Figures needed<br /> <br /> === Audience ===<br /> * Visual language tool for both developers and unexperienced end users of the end product<br /> ** Eg. Phone system<br /> ** Eg. Circuit Simulator<br /> ** Eg. Water-flow simulator<br /> ** Eg. Ecology Simulations<br /> <br /> === Metaphors ===<br /> * Spacial metaphor<br /> ** Grid-layout<br /> ** Like a map<br /> ** Relative position<br /> * Temporal metaphor<br /> * Shows change over time<br /> <br /> === Effectiveness ===<br /> * No figures presented in the paper. We need more literature! [[User:Zlee003|Zlee003]]<br /> * 3D?<br /> * SimCity<br /> * To Do: everyone to look for examples of grid based languages (1 eg each)<br /> ** Grab Richard&#039;s slides about map versus text based directions<br /> * To contrast with freeform languages like raw sketching tools<br /> * Comparison against a spreadsheet</div>
