OUR TEAM Name: Nick Valverde Name: Daniella Orlando Name: Brandon Favre Name: Martisha Clyde Name: Fernanda Diva Name: David Shumate LAB 3A WRITE-UP Descriptive Statistics All the measurements of temperature and pulse with spree device were not precise. Because it did not just consider the temperature and the reaction of the body, but also the change from indoor and outdoor. On the other hand, the measurements using oral thermometer and pulse ox were more accurate and precise, as these devices just considered what was happening inside the body. Heart Rate: Heart Rate Monitor versus Spree Temperature: Thermometer versus Spree Results Analysis Summary/Discussion There are many problems with this device. The first one was the method of showing the temperature. Temperature was only appeared as a color. It would be better if it shows the actual temperature in Fahrenheit and also in Celsius, as it could be easier to use it around the world. It is kind difficult finding the device because of the Bluetooth. It would better if each one had a different name. The temperature and the heart measurement could me measure somewhere else. One of the biggest problems was the changing of the color when we variety between outdoor and indoor, and especially when exposed to the sun. It could have a better insulation to only measure the person’s temperature without including the exposure of the local and climate changes. Nowadays, it is really important for people the cellphone’s battery, and this app just run out it really fast. Spree should be able to record data to store onto the device to be accessed at a later time, like on a computer. This way the battery would have life for more time. To stay measuring, you have to keep moving, it does not take a baseline measurement. It would be better, if it had a button to turn on and turn off, so the person could enjoy more the work out without thinking that you have to stay moving your head. If you are walking, running or cycling, it does not give you a problem. However, if you are working out at gym, it gives, because you have to keep shaking your head while you are seating doing an exercise, for example. Another problem is, this device is not comfortable, so it is hard to stay with it for a long time. They could design it better, with a more comfortable material for the band, more of a relaxed fit. And also, make it someway less pressure on the forehead, because it gives headache if you stay for a long time. The last problem that we figured out, was that this app it is just available at apple store, if they make it available for all platforms, they could have a bigger market. LAB 3B WRITE-UP Target Population and Need The target population of the Cerebro earbud device is college students, who are in desperate need of aid in note taking. According to the National Center for Education Statistics, the number of students attending university in the United States has increased from 15.3 million in Fall of 2000, to 21.0 million students in the Fall of 2014. Many students must sit in lectures where professors teach at lightning-fast speeds, which discourages note taking. In addition, many of these professors place an outright ban on the video or audio recording of lectures. There are no devices on the market, other than audio recorders, that allow for thought-to-text conversion. Audio recorders are limited in that they can only play back an audio file, while the Cerebro headset allows for immediate conversion of the notes of the lecture. Further, the Cerebro, given that it records brain waves, can aid students by providing data on the quality of their sleep. Data from the National Sleep Foundation has proven that only around 15% of students get adequate amounts of sleep nightly. By knowing more about the ways that their brains are affected by lower amounts of sleep, students may be more inclined to sleep more, which would increase their ability to succeed. Problem Understanding Form Device Design Inferential Statistics In this instance, 500 trials were performed comparing the MRI technology used in Cerebro to the more common, "mind code," technology. The Cerebro MRI technology picks up either a zero or a one when a specific part of the brain is active, while the mind code technology does the same. This test proved that there was no statistical difference in the Cerebro's picking up of brain waves in comparison to the more common mind code. Graph This demonstrates that the use of MRI technology allows for the same results as more sophisticated mind code techniques. Where the mind code picks up on a brain wave, so too does the MRI, and thus, Cerebr is proven to be just as effective at picking up brain waves as the mind code technology.
