1 Mobile Data Collection Briefing for the ETLG December 9 th, 2013 By UCLA OIT ECTG Director Rose Rocchio

2 Mobile Data Collection (MDC) Passive Mobile Data Collection Public Mobile Data Collection Crowd Sourced Mobile Data Collection Audience Response Systems Private Mobile Data Collection

3 Passive Data Collection

4 Public Data Collection

5 Crowd Sourced MDC

6 Audience Response Systems Hardware Radio-Frequency Clickers Software Based - BYOD - Mobile versions

7 Private Mobile Data Collection using Participatory Sensing Real Time (always on) Real Place (always carried) Real Context (historical, spatial, environmental, social) Real Applications (civic and environmental data, transportation, health, education)

8 A Tale of Two Tools Native Apps iOS, Android, Web XML script Testing Required Account Needed html5 - Web Based Browser required GUI Authoring No testing needed Anonymous Replies

9 Introducing OPT BYOE Audience Response

10 What is OPT? OPT is an Online Polling Tool It works on any Mobile device with a browser Interactive Polling for classrooms Anonymous for poll takers Authentication required for poll creators Use Cases include: – Geo-distributed classes – Online - Synchronous Office Hours

11 Interactive Polls OPT, is a web-based (clickerless) BYOD (Bring Your Own Device) Audience Response (AR) system available to all faculty & Staff to create polls and is open to all students to take polls (with no additional fees or devices needed) today The Process Create a Poll Collect Data View Results
