Accuracy of a single position estimate for kNN-based fingerprinting indoor positioning applying error propagation theory
Perez-Navarro, Antoni; Montoliu Colás, Raul; Sansano-Sansano, Emilio; Martínez Garcia, marina; Femenia, Ruben; Torres-Sospedra, Joaquín IEEE (2023-06-23)Indoor Positioning Systems usually consider the average positioning error over a set of evaluation samples, or a quartile of that value, as the global error. However, they do not provide a metric for the uncertainty for ... -
BLE-GSpeed: A new BLE- based dataset to estimate user gait speed
Sansano-Sansano, Emilio; Aranda Polo, Fernando Jesús; Montoliu Colás, Raul; Alvarez, Fernando J. MDPI (2020-12-07)To estimate the user gait speed can be crucial in many topics, such as health care systems, since the presence of difficulties in walking is a core indicator of health and function in aging and disease. Methods for ... -
Continuous Non-Invasive Assessment of Gait Speed Through Bluetooth Low Energy
Sansano-Sansano, Emilio; Montoliu Colás, Raul; Belmonte-Fernández, Óscar; Aranda Polo, Fernando Jesús; Alvarez, Fernando J. IEEE (2022-04-22)In the near future, as a consequence of the increasing percentage of elder people with respect to the total population, developed countries will face significant stress on their healthcare systems. The onset of some diseases ... -
