In each of the three tests, there was a statistical significance because the t-test values were less than .05, which indicates 95% confidence. This statistical significance indicates that the difference between the temperatures taken using the sensor and the temperatures taken using the oral thermometer was not merely due to chance. Since the temperature of the oral thermometer is generally accepted as correct, there is a factor causing the sensor to improperly take a temperature reading.
Summary/Discussion
The only device that really worked in the experiment was the thermometer. The app Vital Monitor and the RAIN sensor had quite a few problems, there were a lot of connection issues with the devices and the signal constantly dropped. Some of the groups that were testing the device could not sync with the blue-tooth. When devices and groups were too close together the blue-tooth could not connect with the RAIN sensor, it was picking up multiple signals from multiple devices and could not determine which device it should pick up. We tried it with an iPhone, but the connection kept dropping. Another flaw it had with the iPhone is that the phone could not have the case on it because it affected the temperature of the reading. However once we moved to an iPad the connection got a bit better but still dropped from time to time. It also took quite a while for the RAIN sensor to get a reading on the subject we were using. It took about 30-40 minutes for the device to go from 80 degrees to about 94, the highest temperature only being about 96 (though some groups did get a reading of about 98). Overall the app and the temperature reader need to be reexamined and rethought, the devices did not connect to each other very well, the instructions for the devices were not very clear, and the temperatures that were measured were quite off. The RAIN sensor is also quite inconvenient and logistically complicated because it is not logical to wear a sensor for such a long time and need to be so close to it to get a reading, not many potential buyers will want to go through with that just for the sake of being able to know their temperatures.
LAB 3B WRITE-UP
Target Population and Need
This product, AquaTemp, is targeted towards professional long-distance swimmers and is designed to measure temperature in water. When swimming in cold water, long-distance swimmers could experience hypothermia, which occurs when the body temperature drops drastically and the body is incapable of regulating temperature through homeostasis. This device will monitor temperature of the swimmer while he or she is swimming and will display the temperature in a screen in the swimmer's goggles. In addition, an app will also be created that will display the temperature of the swimmer through wireless connection, allowing trainers, coaches, and officials to ensure that the swimmer's temperature is stable.
Device Design
The AquaTemp cap is made from one of two materials: latex or silicone. Latex caps are for those who swim competitively while the silicone caps are for those who swim recreationally. The device that measures body temperature will be placed within the cap, and both latex and silicone provide a nice, tight, and dry environment for the users' hair and head, which is why they are the perfect materials for our state of the art body temperature measuring system. The sensor inside the cap will read internal body temperature and will transfer the information to goggles that display the readings of the body temperature in real time. We also made sure the sensor is waterproof just in case there is something that happens to cause it to get wet. There will also be an app the user will be able to download and a special feature of the sensor is that it creates its own WiFi hot spot, instead of blue-tooth, which enables the sensor to transfer temperature measurements to electronic devices across long distances. This can be used by trainers of swimmers to monitor their athletes, especially if their athletes are swimming across long distances, such as the English Channel. The cap and goggles together will be sold for 20 dollars for the latex and 23 dollars for the silicone. The app will be free to download for iPhone and Android users.
