Growing an organic indoor location system
Jun-geun Park,Ben Charrow,Dorothy Curtis,Jonathan Battat,Einat Minkov,Jamey Hicks,Seth Teller,Jonathan Ledlie +7 more
TL;DR: This work describes the use of Voronoi regions for conveying uncertainty and reasoning about gaps in coverage, and a clustering method for identifying potentially erroneous user data that facilitates rapid coverage while maintaining positioning accuracy comparable to that achievable with survey-driven indoor deployments.
Proceedings ArticleDOI
Implications of device diversity for organic localization
TL;DR: This work analyzes the diversity of those signal characteristics pertinent to indoor localization — signal strength and AP detection — as measured by a variety of 802.11 devices, and shows that using only signal strength, without incorporating negative evidence, achieves good localization performance when devices are heterogeneous.
Journal ArticleDOI
Implementation of Argus
TL;DR: The implementation of Argus is described, with particular emphasis on the way the authors implement atomic actions, because this is where Argus differs most from other implemented systems.

Automated auscultation system
TL;DR: In this paper, the authors presented a system for automated auscultation and diagnosis of conditions of the cardiovascular system using an acoustic signal emanating from the system via an acoustic sensor.
Proceedings ArticleDOI
Online pose classification and walking speed estimation using handheld devices
TL;DR: Two methods for device pose classification and walking speed estimation that generalize well to new users are described and evaluated, compared to previous work.
