The landmark identification module deploys a decision tree-based approach to recognize the motion states, including normal walking, standing, walking stairs, taking elevators, and taking escalators.
The results show that almost all landmarks can be identified correctly, except for the negligible confusion between normal walking and walking stairs, due to some irregular leg locomotion.
Preoperative QFM strength increased by 28% (p > 0.05) with associated gains in walk, stair-climb and chair-rise times (p < 0.05).
We collected 1000 test samples for each motion state, including taking elevators, taking escalators, walking stairs, normal walking, and standing.
A readout shows steps walked, stairs climbed and calories burned.
Walking, stairs and cycling are more relevant motion patterns.
At baseline, the patient reported maladaptive IPs on the Brief Illness Perception Questionnaire Dutch Language Version and limitations in walking stairs, cycling and walking.
Recently, user motion states [19], including walking stairs and taking elevators and escalators, have been considered as indoor landmarks to aid indoor positioning.
Among these motion states, walking stairs, taking elevators, and taking escalators can be considered as landmarks to aid user heading estimation.
We translated the Walking Stairs, Walking Ability and Rising and Sitting Questionnaires according to published guidelines.
