Based off the T-test in the heart rate group, it suggests that it is not statistically significant, meaning that the spree and the gold standard had very close readings. However, the Pearson's R test shows that there is a possible correlation between the two measuring devices.
In the temperature group, the results were statistically significant in the T-tests, suggesting that the spree and the gold standard had a wide variation in temperature readings. Therefore, the Spree's ability to read temperature were inconsistent with the thermometer. The Pearson's R test also shows no correlation between the two measuring devices.
Summary/Discussion
Design Flaws
One of the design flaws for the Spree device was that it was trying to measure the temperature from the forehead than the usual core temperature from under the armpit or tongue. As for the heart rate it would be ideal to have an alarm when the Spree reaches above the normal level of a human heart beat. Bluetooth technology with this headband but it would lose connection very easily and was difficult to connect to via smartphone. It was hard to distinct from each other Spree that were close by. Another physical gimmick of the Spree is that there was no way to tell if it had any battery life or if it was in full power. It would have been more advantageous if it had measured oximetry as well since the forehead is viable for that position. It was very bland and unfashionable. A recommendation would be to put some designs or cotton-based band along with a variety of colors and options of other types of apparel. Its not economical to purchase this product because of limiting functioning and unfavorable ergonomics for a price of three-hundred dollars.
Conclusion
The Spree device is not ideal for athletic wear. This customer complained of discomfort from wearing the device and felt it was awkward. There are a variety of issues with the Bluetooth technology and measuring ability alone. Economically, it is not priced ideally for the current level of functioning. It may be more ideal to find a cheaper or higher functioning device to purchase instead.

Device Design
The image on the left depicts the outward appearance of the DNAtion At Home DNA Kit. Along with the logo, the front of the device will feature a touch screen where the user can interact with their results via visually aided charts and graphics. From this screen, the user can also organize and save multiple sequences based on date, person, or any other factor they see fit. From this image, the input slide, the on/off button, and the open/close button are visible on the side of the device.
The image on the right depicts the function of the device’s moving parts. The input slide acts similarly to a CD drive on a laptop. When the user presses the
open/close button, the slide extends from the side of the device. On the surface of this extension, there is an indentation to insert the microscope slides containing the DNA sample. To insert the DNA sample for sequencing, the user can either press the open/close button again or gently press on the extension slide. The Extension will protrude and retrieve automatically.
Device Features:
After Sequencing DNA data, the following is displayed: Pre-conception
Probabilities of Disorder and/or if it is present already
Find potential risk to diseases
Ancestral heritage
Post Conception
