Towards personal stress informatics: comparing minimally invasive techniques for measuring daily stress in the wild
نویسندگان
چکیده
Identifying episodes of significant stress is a challenging problem with implications for personal health and interface adaptation. We present the results of a study comparing multiple modalities of minimally intrusive stress sensing in real-world environments, collected from seven participants as they carried out their everyday activities over a ten-day period. We compare the data streams produced by sensors and self-report measures, in addition to asking the participants, themselves, to reflect on the accuracy and completeness of the data that had been collected. Finally, we describe the range of participant experiences—both positive and negative—as they reported their everyday stress levels. As a result of this study, we demonstrate that voice-based stress sensing tracks with electrodermal activity and self-reported stress measures in real-world environments and we identify limitations of various sensing approaches.

متن کاملHyperglycemia and antibody titres against heat shock protein 27 in traumatic brain injury patients on parenteral nutrition
Objective(s):Hyperglycemia worsens the neuronal death induced by cerebral ischemia. Previous studies demonstrated that diabetic hyperglycemia suppressed the expression of heat shock protein 70 and 60 (HSP70 and 60) in the liver. IgG antibody titres against heat shock protein 27 (anti HSP27) were measured to determine whether hyperglycemia exacerbates ischemic brain damage by suppressing the exp...
متن کاملModeling of Tactile Detection of an Artery in a Soft Tissue by Finite Element Analysis
Nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. In this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. In this modeling, three 2D models of tissue have been created: tissue, tissue including a tumor, and tissue ...
