Solution 2: We can redesign the wireless connectors in the Spree headband so that they will generate a stronger wireless connection with the phone application. Also, we could have the spree band bluetooth names custom so it is easier for the user to identify which band to connect to. <br> | Solution 2: We can redesign the wireless connectors in the Spree headband so that they will generate a stronger wireless connection with the phone application.

Solution 3: We can redesign the Spree headband with different materials such as the airy materials used to make running shoes. We want the headband to be light so that the person wearing it will be comfortable wearing the headband often while working out. <br> | Solution 3: We can redesign the Spree headband with different materials such as the airy materials used to make running shoes.

Solution 4: A major design flaw inherent in the spree headband was its inability to take accurate readings of internal body temperature, mainly due to the fact that it takes temperature readings from the skin, which does not always reflect internal temperature. A modification that may be able to remedy this issue would be to make an internal device, possibly one that could fit in the mouth much in the way a retainer does. This would allow for much more accurate temperature readings and allow temperature to display as an exact number rather than a temperature range. <br> | |||
Solution 5: Another flaw in the headband was the inaccuracies in measuring heart rate. This could be due to its position on the body, as a headband, the spree headband can be subjected to jostling and shifting, which could throw off readings. One potential fix for this problem would be to do away with the headband design entirely and follow the example of previous devices which strapped to the chest with a heart rate monitor positioned directly over the heart itself. <br> | |||

Figure 1: Graph of the heartbeat results obtained from the gold standard and the spree. The mean heart rate from the gold standard was observed to be 92.52 beats per minute and the mean heart rate from the spree headband was observed to be 92.82 beats per minute.
Figure 2: Graph of the temperature results obtained from the gold standard and the spree. The mean temperature from the gold standard was observed to be 97.6 degrees Celsius and the mean temperature from the spree headband was observed to be 102.9 degrees Celsius.
Inferential StatisticsT-tests were used rather than ANOVA tests, because in each group only two sets of data were being compared.

Summary/Discussion
Problem 1: The headband needs to be on really tight to ensure it does not fall off the user, which causes discomfort Solution 4: A major design flaw inherent in the spree headband was its inability to take accurate readings of internal body temperature, mainly due to the fact that it takes temperature readings from the skin, which does not always reflect internal temperature. A modification that may be able to remedy this issue would be to make an internal device, possibly one that could fit in the mouth much in the way a retainer does.
