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, and also be be 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-based 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 7 / Windows 8 / Windows 10.
- CPU: At least 1.5 Ghz, 2 Ghz or better preferred.
- RAM: 1 GB minimum, 2 GB or more preferred.
- Disk Space: At least 2.65 GB free disk space is required.
Want to help scientists help you?
Researchers at the Spatial Intelligence and Learning Center (SILC)
are gathering a corpus of sketches using CogSketch. CogSketch is the sketch understanding software that we
are creating, which is available for free from our web site. It has two purposes.
First, we are using it to explore how people reason and learn. Second, we are exploring how to incorporate
sketching into education, to improve student learning. By gathering people's sketches, scientists will be
able to do analyses that will help them with both of these missions. If you want to participate, all you
have to do is download CogSketch, and indicate your acceptance when you install the
software. (If you change your mind, there is a "Phone Home" setting in the software preferences.)
