CogSketch
People sketch to work through ideas and to communicate, especially when dealing with spatial matters. Software that could participate in sketching could revolutionize spatial education, and provide a new kind of instrument for cognitive science research, as well as being an important scientific advance in its own right. Our goal is to do the research and development needed to create a sketch understanding system that can be used as an instrument for cognitive science research and as a platform for educational software. This system, called CogSketch, will be one of the products of the Center. Our vision is that, in ten years or less, sketch-base educational software can be as widely available to students as graphing calculators are today. To achieve this vision will require tight collaboration between the AI researchers on the CogSketch development team and psychologists, learning scientists, and educators.

System Requirements:
- Hardware: Tablet PC preferred, but not required. If you are using a desktop or a traditional notebook, we highly recommend adding an inexpensive Wacom tablet, because you will find it a lot easier to draw with a pen than with a mouse.
- Operating system: Microsoft Windows XP / Vista. It should still run on Windows 2000 but that has not been tested.
- RAM: At least 1GB, 2 GB preferred.
- Disk Space: At least 1.5 GB free disk space is required.
CogSketch, version 1.12
-
Installer for version 1.12 (426 MB) [5/4/2009]
- The above link will take you to the form required to download the installer for
the latest version of CogSketch
- User Manual (1.4 MB) [5/4/2009]
- The User Manual is included in the installer above — this link is just
for those who would like to look at the manual without installing CogSketch.
- Knowledge-Base for v1.12 (402 MB) [5/4/2009]
- The knowledge-base is also included in the installer above so you do not need to
download this separately. This is for those who want to restore their knowledge-base
to its original state. Download this file, unzip it, and choose "Restore Knowledge-Base"
from CogSketch' FIRE menu.
Changes since v1.11:
- Bug fixes in the Qualitative Mechanics code. Also now includes all the correct QM rules (v1.11 had some old and incorrect rules).
- It was possible to get the ink-processor stuck in a disabled mode if you slid the pen/mouse while double-clicking a glyph. That’s been fixed.
- The glyph properties editor for glyphs that represent relations on the metalayer was not always showing the correct values for the relation’s arguments. This has been fixed.
- Perceptual Sketchpad example #1 failed to build a comparison between the two entities. This has been fixed.
- CogSketch now supports KB Patch Scripts, so that we can send out updates to the knowledge-base without requiring you to re-download the entire knowledge-base.
- You can drag sketches from Windows Explorer to the main-pane of CogSketch (the window with the dark-gray background).
- Removed some old pre-perceptual-sketchpad menu options that didn't really work all that well:
- Compare Glyphs
- Mark
as A - Mark
as B
- Right-click menu now has option for editing the glyph properties.
