This section lists experiments made within the Higgins project. We attempt to report conclusions and data from as many of the tests wemake as possible, be they user studies, comparisons of techniques, or simple proof-of-concept tests.

The section also contains brief descriptions of data collections made within Higgins. Data and analyses may be included if time permits.
