They are developing a new body temperature and heart rate monitor for smart phones and want to check out the competition. The latest such device is from Spree Sports (www.spreesports.com) and they claim the device can accurately measure body temperature and heart rate. Your assignment is to assess how valid the device is as well as to identify any design flaws by comparing the temperature and heart rate readings on the device to those of an oral thermometer and pulse oximeter. | ||

Lab 3A: “Device Validation”
Note: Make sure the iPhone is always within a few feet of the sensor.
1. PREPARE FOR FIRST USE: 2. PLACE SPREE ON YOUR HEAD: 3. OPEN SPREE APP: 4. CONNECT TO SPREE: 5. SELECT YOUR “ACTIVITY” AND YOUR “MARK”: 6. BEGIN WORKOUT. Lab 3B: “Device Development and Marketing”You have assessed the competition’s device (the Spree Headband) and have decided to move forward on designing your own body monitoring device. Based on the obvious flaws in your competition’s devices, design an improved body monitoring device. There are two components to this lab. The first is the written component in which you present your design, “data”, and analysis. The second is the commercial that will be shown in class where you market your device to a target population. Grading Scheme: Commercial (Grading by Peers and Instructors) Score scaled to 20points
