● Problem● Our Solution● Market Solution● Constraints

○ Technical○ Practical

● Approach● Progress ● Timeline

Topics

Problem● Cost effective fitness band

● The SMART Band should not be too complex

● Creating a device that will compete with similar devices i.e. Fitbit, Tom Tom Runner

● Create a product that is different from gadgets already on the market

Our Solution● easy to use

● affordable

● rechargeable

● counts steps taken

● location services

● pulse reading

● temperature sensing

● storage of data

● Graphical User Interface (GUI) for customization and data dump

● ability to track trends

● Similar products already on the market

○ Apple Watch

○ Fitbit

○ Tom Tom Runner Cardio

Market Solution

Market SolutionSimilar Products What they offer What SMART BAND offers

Apple Watch

Goals for workouts Workout Applications Heart Rate monitor Mainly a phone on your wrist

GUI to track progress and customizeGPS for tracking Pedometer for step count Pulse sensor Ambient Temperature Sensor

Fitbit

Different devices for different abliltiesBasic model only offers steps, calories, and distanceHave to spend more for more options

All options/sensors offered on one device at one price
