Within the field of actigraphy, numerous findings support this claim, such as the emergence of power-law distributions and the presence of 1\/f noise in human locomotor activity. Recently, we discovered that the spectral characteristic of human activity \u2013 which includes 1\/f noise at frequencies greater than the daily periodicity \u2013 is universal, as both the raw acceleration of the<\/p>\n<p>wrist and the diverse kinds of activity signals (i.e., acceleration data compressed in varied ways) follows the same spectral nature. Here, we demonstrate that this spectral characteristic<\/p>\n<p>persists for daily human activity in general by analysing datasets from various sources containing activity or acceleration signals of healthy, free-living subjects.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Keywords<\/strong>: 1\/f noise, actigraphy, power law, scale-free nature, human dynamics<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Revealing the Generality of 1\/f Noise Based Spectral Characteristics of Human Activity Across Different Datasets 2023\u00a0International\u00a0Conference\u00a0on\u00a0Noise\u00a0and\u00a0Fluctuations\u00a0(ICNF),\u00a0Grenoble,\u00a0France,\u00a02023,\u00a0pp.\u00a01-4,\u00a0Publisher: IEEE (Institute of Electrical and Electronics Engineers) DOI: <a href=\"http:\/\/publicatio.bibl.u-szeged.hu\/30006\/1\/ICNF_2023_Maczak_4_page_full.pdf\" target=\"_blank\" rel=\"noopener\">10.1109\/ICNF57520.2023.10472765<\/a> &nbsp; B\u00e1lint Macz\u00e1k 1, Csenge G.
