Figure 18 shows a comparison between the measured m-D signature of a human walking in free space and those of the same target walking behind a 15 inch wall and a 12 inch cinderblock wall.
Kiyomiya said he saw the target walking down to the stadium from the dormitories before the game.
Classification performance was assessed between, targets walking away vs target walking towards the sensor, male vs female and identification performance was also assessed.
Fig. 16 Foot trajectory at target walking velocity 0.33 m/s with 0.18 m of stride Fig. 17 Foot trajectory at target walking velocity 1.2 m/s with 0.18 m of stride.
An example of the signature of a personnel target walking with an object in a hand is given in Figure 17.
Pedestrians who texted while walking toward a previously identified target showed greater lateral deviation from the remembered target, walked longer distances, and took longer to arrive than either their non-distracted or talking counterparts (Lamberg and Muratori 2012).
Although DHS is independent of silhouettes or landmark tracking, it is ineffective when the target walks toward the camera as the DHS degenerates into ribbon and no strong symmetry can be observed.
A variant of this task is triangulation by walking or pointing, which involves viewing a target, walking on an indirect path and, when prompted, walking or pointing toward the updated target [35], [41].
Self-monitoring has shown particular promise when used in interventions that target walking because it can increase self-efficacy (Du et al., 2011) and reduce perceived barriers (Wilbur, Miller, Chandler, & McDevitt, 2003), a finding supported by this review.
Thirteen subjects were examined applying the newly designed target-walk paradigm and for comparison the standard prosaccade task.
