Roberta is interested in improving her batting average this softball season. She knows her swing could use some work in order to improve her hand-eye coordination and strike the ball more often. Roberta can apply technology to this individual goal by using a:

Heart rate monitor to track her heart rate when up to bat
Pedometer to see how many steps she runs during an average 7 inning game
Spreadsheet to track her swing tendencies for the pitch count
Video camera to analyze her head movement when contacting the ball
