Fight crime with tech.
At University of Maryland, there has been an increase in robberies on and around campus at night. Safe on the Streets is the culmination of a semester-long Human Computer Interaction project to mitigate this problem through the use of technology.
Safe on the Street tracks a user as they walk at night. They are periodically required to enter a passcode. If the user does not enter the passcode, the authorities/emergency contacts are alerted with the user's GPS location.
