2 The Problem Design a method for alerting a visually impaired swimmer when to flip turn. Problems with this method –Requires dedicated personnel –Inconsistent –Lack of independence –Uncertainty inhibits full potential Current “technology”:

3 Our Customer Professor Richard Strebinger Coach Annie Sawicki Operating Environment “Our pool” (Rolfs Aquatic Center) Underwater Parts of the Problem Sense the swimmer Alert the swimmer

4 Constraints and Considerations Electricity + Water = Bad Regulations prohibit auditory signaling Swimmer must wear device so minimal drag is desired Impact on device Signal interference from multiple swimmers and noise at surface Different sizes of users - calibration?

5 Features for Solution Sensors at each end of lane Determine if swimmer is inbound or outbound Vibrating device Failure signal/ Low battery warning Calibration Use of blacked out goggles

6 Useful Technologies SportzJam underwater radio Cell phone vibration motor CAD/CAM prototypes Sensor research at ND

7 The Plan Research sensor technologies Understand vibration technology Study underwater power sources to learn about waterproofing and safety Make decisions for product design based on research –Determine sensor type –Determine notification method –Develop interfaces: sensor to processor, processor to swimmer –Device use logistics Product design
