Wearable cameras enhance understanding of lifestyle behaviors and health
Washington, February 6 : Researchers are claiming several new benefits of wearable cameras in their latest study because they believe that the technology could provide health insights by maintaining good relationships between lifestyle behaviors of a person and their health outcomes.
Three studies report on the latest preventive medicine research using Microsoft's wearable camera, the SenseCam.
"Wearable cameras and their associated software analysis tools have developed to the point that they now appear well suited to measure sedentary behavior, active travel, and nutrition-related behaviors," says author Aiden R. Doherty, PhD, from the Department of Public Health at the University of Oxford, United Kingdom.
"Individuals may recall events more accurately after reviewing images from their wearable cameras, and in addition aspects of their immediate cognitive functioning may also improve."
A study by researchers in Ireland analyzes how wearable cameras were employed to improve the recording of dietary intake among jockeys, Gaelic footballers, and physically active college students.
The researchers, led by Gillian O'Loughlin of Dublin City University, report that images from the SenseCam provide additional information regarding dietary intake patterns, such as portion size, forgotten foods, leftovers, and brand names. Using wearable cameras also revealed a significant under-reporting of calorie intake, which is a prevalent and critical error of food diaries and self-reporting.
Adding wearable cameras to dietary analysis provides a valuable tool not only for athletes and sport populations who closely monitor calorie intake, but may also present dieticians and health providers with the ability to better assess and treat those in need of dietary management.
The study has been published in the American Journal of Preventive Medicine.
