4. LIVES The goal of LIVES is to provide illiterate people in developing countries with  An asynchronous learning tool based on auditory cues utilizing the existing telephony/mobile infrastructure  Easy-to-use Learning Management System & Learning Content Management System 3 http://lives.cs.ubc.ca

5. Overview of The System The features and functions of the LIVES system What is it? What can it do for us? 4 http://lives.cs.ubc.ca

6. Figure 1: The LIVES system calls registered students 5 Students can register with LIVES with mobile number preferred time range to receive calls preferred language LIVES detects newly uploaded lectures/quizzes and calls the students at their preferred time Overview of The System http://lives.cs.ubc.ca

7. Figure 2: A user picks up (or does not pick up) the call from LIVES 6 A student does not/cannot pick up the call will be called again within the preferred time range (or) will be called the following day, if the preferred time range is exceeded A student picks up the call will listen to lectures answer quizzes (or) will indicate unavailability Overview of The System http://lives.cs.ubc.ca

8. Figure 3: A user hangs up during the call 7 A student hangs up during the call (or indicate unavailability) Heard lectures are saved will be called again will be provided with unheard lectures again will be provided with unanswered quizzes again Overview of The System http://lives.cs.ubc.ca

9. Figure 4: User leaves a feedback using numeric input 8 A student answers questions using a numeric input LIVES asks a student to answer multiple choice questions by pushing the number key LIVES stores student’s answers in the user-profile database Each user’s profile can be retrieved later Overview of The System http://lives.cs.ubc.ca

10. Figure 5: LIVES responds to the user’s answer 9 LIVES responds to the user’s answer For a correct answer Informs the answer is correct Provides an explanation to why the answer is correct (optional) For an incorrect answer Informs the answer is incorrect Asks again for a correct answer Overview of The System http://lives.cs.ubc.ca

11. Figure 6: User progress tracking by user-profile-database 10 The user progress tracking by user-profile database general user information preferred time range list of received lectures list of received quizzes student’s answers to quizzes overall GPA And so on..
