5.  On the market today, monitoring armbands cost anywhere from $100 - $200.  Other armbands do not monitor ambient temperature.  Other products have complex computer application.  Some products have chest straps.

6. [2] [3] Mio 0034US – BLK, Energy Pro Plus Chest strap with heart rate zone indicators. $99.95 Polar RCS5 Red Watch Chest strap with calorie counter and is water resistant. $179

7.  Develop the product to cost around $100.  Monitor ambient temperature.  Design computer application to be easy to operate for any age user.  Monitor heart rate with finger strap.

8.  Technical  Practical

9. NameDescription Battery LifeThe MyBand Fitness device will run for a minimum of four hours. Capturing DataThe device will capture data at a maximum sample rate of 200 Hz and store the data on separate flash memory of 8 GB. DisplayThe wrist device will display sensor values, warning messages. MeasurementThe product will measure heart rate and ambient temperature accurately. Physical ParametersThe MyBand Fitness device will fit comfortably around one’s wrist.

10. TypeNameDescription EconomicCostThe product will cost around $100. ManufacturabilitySizeThe device will be small enough to wear on user’s wrist.

11.  To be competitive on the market, must cost around $100.

12.  The wrist device will have to be small and weigh less an 1 pound to fit comfortably on the wrist.  Wrist device will have a detachable band.
