The uBracelet is designed for students to easily communicate personal information to their friends, such as when they have free periods. Rather than having to stop and remember their schedule off the top of their heads, they can simply flash their bracelet at their friend and they will know whether they can meet up. In this case, each color correlates with a free period: red is first period, yellow is second, green is third, and so on. The bracelet could alternatively be used to share other personal information, such as mood, where blue might mean “having a bad day” and red might mean “approach with caution.” Or the bracelet might indicate relationship status, with magenta as “in a relationship” and green as “looking for someone.” In general the uBracelet gives the wearer a way to easily share personal information about what is going on in their life.
