1 Abstract This report describes the development and features of Experimenter, an application based on the EEG capabilities of the Emotiv EPOC headset. As a research tool, Experimenter allows a variety of experiments based on classic stimulus-presentation paradigms to be run using the Emotiv. Unlike most EEG setups, however, Experimenter not only records data but also attempts online analysis a...

detailed in Table 1. The washers are used to center and space lenses inside the eyepiece body. The washers provide a useful range of dimensions for accommodating different size lenses. The elastic rings are slightly oversized, and are used to snugly hold the optics inside the eyepiece body. The elastic rings (which can be inserted and removed) allow for fast design changes and quick experiments...
