The Exerspy by Nico Moschetto

I. Introduction
Have you ever wanted to lose weight? Ever feel like you couldnt do it because its because you cant keep track of what your eating or how much physical activity you get? Well, now you can! With the brand new exerspy created by bodymedia. Bodymedia is a fitness group dedicated to finding new breakthroughs in weight loss, muscle gain, and staying in shape. This was a project launched in august 2009 by dotfit (dotfit being a distributor of the product). Its as simple as plugging into your computer and recieving your daily readings. This lets you know if you need more physical activity and if you need more sleep (if worn at night).

II. Discovery
Before the exerspy was invented there were many attempts to put together a system of tracking calories and footsteps. The closest they got was a stepcounter. Now, using modern day technology we can track how many calories we eat, how many steps we take, and our daily physical activity. The exerspy has sensors on the underside of the armband that sample physiological data at a rate of 32 times/second. This armband has four diffferent sensors that process this information. One of them is the heat flux sensor. This sensor measures the rate at which heat is dissipating. This contributes to the energy expenditure measurement. The two access accelerometer measures all motion including how many steps you have taken. This measurement can be seen after you plug it into your computer. This device also reads your resting energy expenditure, active energy expenditure, and physical activity duration. The reason for so many sensors is because if you only had one sensor measuring movement, a lot of activites would look the same. With both the movement sensor and the heat sensor, the exerspy can tell the difference between other activities. For example, riding in a truck can cause a lot of movement, which causes the movement sensor to detect that you are doing something active, while the heat sensor senses no rise in activity, causing the device to recognize that the activity going on is one not requiring very much effort, while the movement sensor alone would detect riding in a shaky truck as a physical activity.

III. Biography of Investigator

Bodymedia was founded in 1999 as a pioneer in developing wearable body monitoring systems. They have helped people lose weight and improve preformance ever since. They are the ones behind the multi-sensor technology which has allowed them to monitor calorie expenditure, steps taken, and sleep efficiency. They have also geared their products twards being comfortable and being over 90% accurate.

IV. Impact on the World/Humanity

This product has a very useable program with as simple reqirements as owning a computer, which 66% of Americans do. This device could drastically change the way obese people look at their dieting habits as well as excercise habits. This device could also contribute to the weight that needs to be lost in America currently. Knowing the problem is half the battle. Knowing what to do about it is 1/4, but doing something to fix it is the other 1/4. Yet somehow, people are still too lazy to get up and do anything. So if your fat and sitting here reading this, get off your fat lazy buttox and do something about it!

V. Journal Article Review

 My source for a journal article was provided to me by Michael Oviedo. His presentation on how the DotFit exerspy worked was very helpful to my research. I was provided with accurate information about the exerspy, how it works, and why it is helpful to people who want to lose weight or gain muscle. This was a much better source than the internet reviews that I googled, which only gave me the same information ten times. In my opinion it is much better to have first hand experience with the topic and the people around the resources than to wing it on the internet or even books for that matter.
