Description
Summary:This editorial focuses on analysis window issues from the perspective of EMG-based multifunctional prosthesis control. However, the work described can be extended to other forms of window-based biosignal classifiers, such as brain machine interfaces that use neural spike-counting algorithms for intracortical data or those that use electroencephalogram recordings. Many researchers have made decisions about analysis window attributes with little regard for the overall delay created in the real-time system, and these delays should be considered and discussed in each article that is published on this topic. In this vein, this editorial provides quantitative assessment of the effect of various analysis window attributes on the range of delays that can be produced between the intended change in movement class and the controller's associated output decision for one type of controller. The author and his colleagues recommend using an overlapped window approach because it produces a more consistent controller delay and decreases the maximum delay produced by the controller.
