Figure 6From: Enhancing Wi-Fi fingerprinting for indoor positioning using human-centric collaborative feedbackBaseline system precision, without user feedback, training area. The precision of first three scans (red curve) is much lower than later scans (green curves for scan 5,10, and 15 and blue curves for 18, 19, and 20). However, the blue and green curves are very close to each other, indicating the precision after four scans is not improved significantly.Back to article page
