From cl2e+ at andrew.cmu.edu Thu Feb 16 16:39:28 1995 From: cl2e+ at andrew.cmu.edu (Christian Lebiere) Date: Thu, 16 Feb 1995 16:39:28 -0500 (EST) Subject: New Model Message-ID: John Rieman just contributed to the ACT-R repository a model of interface learning using analogy which he developed at the University of Colorado. A short description of the model is included below, followed by instructions on how to retrieve the files. Contributions of models, data, code or papers to the ACT-R repository are always welcome. Send me email for instructions. Christian Lebiere =============================================================== ABOUT THE MODEL This is a model of a Macintosh user who knows Microsoft Word and is learning to use the Cricket Graph graphing program. The user applies a "label-following" strategy to locate widgets in the interface that might advance the task goals -- that is, the user looks for widgets labeled with words that also appear in their unsequenced set of goals. The user then tries to achieve their task using those widgets. In the process, the user learns, using analogy to experience with MS Word, about interface affordances and situation-specific procedures. Four files are supplied: - README: this file - cg-model-description.rtf: a chapter from my dissertation describing this model and several related models at a high level. This is in rtf format. - act-r-code-changes: several minor changes to the ACT-R code that must be made before the model will run - cg-model-code.3-25-10: the complete ACT-R model - cg-model-trace: a trace of running the model The model was developed in the version of ACT-R that just preceded release of the book (version 2.0), with the changes described in the code-changes file. It runs fairly efficiently on a PowerBook 160. - John Rieman rieman at cs.colorado.edu October 6, 1994 =============================================================== Access Instructions: ------------------ The latest version of ACT-R is available on-line at three locations, listed here in increasing order of accessiblity. If you have access to the Psychology servers at CMU, the Mac version is on server Great Britain, volume Paradise. The full repository is on the Largo server, Public volume. If you have access to AFS, the directory is /afs/andrew/hss/psy/act-r. Otherwise, you can FTP it at largo.psy.cmu.edu (128.2.248.186) by logging in as anonymous, in the directory public/ACT-R.

The paradigm of such a task would be working with computer-based display simulating an air traffic control. While this may not be the exact task, it is representative in that it involves working with a visual interface, complex skill acquisition, and real time performance. The position would start flexibly sometime next year (1995). If interested, please contact John Anderson (ja+ at cmu.edu).
