The aforementioned experimental protocol was used to set up the brain-controlled robotic simulators to explore the performance of the proposed SSVEP-BCI in Studies I and II, as shown in the following subsections.
1)
Study I:
Trade-off between processing window length and smooth movement: The aim of this study is to find the most suitable processing window length for the speed controller to help users move the object smoothly at an acceptable speed.
The experiment protocol is shown in Figure 4.
The robot was supposed to move following the outputs of the speed controller when completing a transportation task.
To create the outputs, the brain signals were converted into velocity profiles (VPs) using both the RF poly2 predictive model and the simple MA in accordance with two rules, as explained earlier.
The researchers considered both the ability to maintain stability in the carrying of objects (or the box in this experiment) and the average moving speed.
The stability of the box was measured by the deviation of a central mass in the box on the robotic plate space (2D plane).
The deviation of the box in this study was the Euclidean distance between the original and final positions of the box on the 2D plane.
To obtain the most suitable processing window length, the length was varied from one to five seconds with a one-second step.
Finally, the mean of the average speed was compared to the deviation of the box from 10-folds (leave-one subject-out cross validation).
The one-way repeated measures analysis of variance (ANOVA) was used for statistical analysis.
