Stanford University, Fall 2002 ED 225x - Persuasive Technology in Education Me-Go Chika Ando, Andrea Kulkarni, Ken Rafanan, Lori Takeuchi Slide #3 A Week in the Life with Me-Go Four other kids on Aditya’s Me-Go Team also use Me-Go to record their diet and exercise activity. At any point in the day, Aditya can view who’s walked the most steps so far today. Avatars representing other teammates appear on Aditya’s Me-Go when they are walking and their pedometers are engaged. On Saturday, Aditya logs onto to see how well he met his fitness goals for the week. He also compares his teammates’ performance against his own. On Sunday evening, Aditya visits on his home computer to enter in his weekly diet and exercise goals. This week, Aditya decides to limit his junk food intake to three servings, and walk at least one mile per day. Pizza or turkey sandwich for lunch? Aditya chooses the pizza, which he enters into his Me-Go. Mrs. Johri tracks her son’s entries from work, and calls Aditya to discuss his decision to eat pizza. Before lunch tomorrow, Me-Go will conveniently remind him to think twice about ordering pizza again. A built-in pedometer tracks Aditya’s steps all day long. Aditya also enters the half-hour of soccer practice he had after school and the two extra flights of stairs he climbed between second and third periods into Me-Go. At the end of each week, the team is awarded points for cumulative achievement among members. The goal is to outscore other Me-Go teams around the country. The Web site keeps records of past scores so that Aditya can track progress of both team and individual performances over the long run.
