N2 - Future computers will be more mobile, which will require new interaction methods. Accordingly, one might harness electroencephalographic (EEG) activity for computer control. Such devices exist, but all have limitations. Therefore, a novel EEG-based control was tested, which monitors the Steady-State Visual Evoked Response (SSVER). Selections are attempted by fixating a flickering target. A selection occurs if a SSVER is detected. To assess the device's relative performance, a mouse and the SSVER-based control were used to acquire targets of various sizes and distances. Accuracy and speed were measured. Overall, accuracy was poorer and acquisition times were longer with the SSVER-based control. However, the performance levels attained by the SSVER-based control might be adequate when manual controls are problematic, such as in assistive technology applications. In addition, in contrast to the mouse, SSVER-based acquisition times were insensitive to variations in target distance, which might serve as an operational advantage in certain applications.
