- So there is actually an organization about preventive medicine.
- In the USA the organization journal name is American Journal Of Preventive Medicine.
- I think, from the name, this suggests about a medical foundation that research a method to prevent disease and illness.
- Wearable cameras and additional software analysis tools can be used to measure sedentary behavior.
- Here is the definition of the sedentary behavior.
- Sedentary behavior refers to any waking activity characterized by an energy expenditure less and equal then 1.5 metabolic equivalents and a sitting or reclining posture. In general this means that any time a person is sitting or lying down, they are engaging in sedentary behavior.
- This definition is taken from this website, http://www.sedentarybehaviour.org/what-is-sedentary-behaviour/.
- So, I think wearable camera can be used as measurement from what they are usually multiple sensor.
- Measurement then will be given by the software analysis tools.
- I suggest that this software analysis tool is like a "state of the art" computer vision program to sort the video based on events that the user wants to know.
- Wearable camera can be used to detect these kind of behaviors.
- Active travel behavior (walking, ...).
- Nutrition related behavior (diet, ...).
- Sedentary behavior.
- There is this person named Aiden R. Doherty from Department Of Public Health from University Of Oxford.
- I am not sure is he will be relevant in my project or not.
- The idea of using camera is to make the wearer to be able to recall events precisely after reviewing images back from the camera.
- Additionally, immediate cognitive function might also improve.
- I am not sure what is immediate cognitive function?
- The closest Google search query result in Wikipedia entry about working memory.
- Working memory is a cognitive system with a limited capacity that is responsible for temporarily holding information available for processing.
- Basically the short - term memory as it is mentioned in my course about learning on how to learn.
- Here is the link to the Wikipedia page, https://en.wikipedia.org/wiki/Working_memory.
- There is this paper titled, "Using The SenseCam To Improve Classifications Of Sedentary Behavior In Free - Living Settings".
- In this paper there will be defined what is the advantage of using camera compared to use any sensor like accelerometer.
- The thing here is that, when studying about human interaction there should be context for every value input from sensor.
- With accelerometer context agent is necessary.
- So why not using whole video instead.
- In the end there would be context agent that would likely to be human.
- There is this woman named Jacqueline Kerr that found TV and screen based human activity can be traced correctly by using accelerometer.
- In the end the resultant behavior will be summarized by human.
- So in term of step, using accelerometer and video camera should not matter that much.
- However, information contained in accelerometer is limited.
- Where when using camera, there could be limitless amount of thing those can be inferred.
- Study research from Ireland use video based wearable sensor to manage diet of athlete or any physically active student.
- SenseCam provides more information regarding dietary intake patterns.
- The informations here are such as these.
- Dietary intake patterns.
- Food's brand name.
- Forgotten foods.
- Leftovers.
- Portion size.
- This eliminates error on self - reporting on food diaries.
- These videos also provide the professionals (doctor or nutritionist) on how to give correct and proper feedback to the SenseCam wearer.
- The overall effect of using SenseCam and doing self - evaluation is cognitive stimulant in short term.
- Reading the diary entries from SenseCam was found to improve autobiographic memory by prompting events into the images.
- There was a hypotheses about using SenseCam for memory rehabilitation.
- However, for using SenseCam for memory rehabilitation further researches are still necessary.
- There was also suggestion that wearable camera sensor like SenseCam could be use to treating neurodegenerative diseases like Alzheimer.
- Smart phone was also suggested as a possible tool to mimic and replace the functionality of SenseCam.
- There is an article by Paul Kelly about ethics on using intrusive camera based wearable sensor in public spaces.
- There should be an ethical research about this going on the background.
- Here is the full screenshot of the full article.
