Decoding trajectories represented by SSPs (left: linear; middle: cosine; right: circle). Twenty-five sample points from a continuous trajectory (shown as a black dotted line) are bound with a “cue” trajectory (e.g., time) and summed together as an SSP. To decode the interpolated position from the SSP, 144 cue points are used. These decoded positions (after the cleanup procedure) are plotted with a dotted gray line. Snapshots of the similarity plots computed using decoded positions are plotted underneath.
