I have conducted research on a number of projects involving spatial reasoning, visual or physical search, and measuring path deviations. Some of these projects include:
Pathmapping
In a number of fields of behavioral science, it is important to be able to take a path created by one person or entity, and compare it quantitatively to another–regardless of the timing of the path or how many segments the path is represented as. The ALCAMP algorithm was developed to use an optimization approach to measure the difference (in terms of area) between two paths. In the figure on the right, you see some of the particular issues that must be solved in order to accomplish this.
