  3. Background • What is Carnegie Mellon On Board? • Team comprised of multi-disciplinary CMU students and Professors • Team split into specialized groups • What are the team’s goals? • Assist Voyager selecting layout, equipment and education support systems for future vessel • Improve current processes and utilize new technology

  4. HCI Role • Analyzed current Voyager program • Addressed strengths and weaknesses • Considered requirements for new vessel • Incorporated Voyager wish-list • Researched ways to enrich student experience and aid Voyager instructors • Proposed vision, provided guidance and created framework for On Board team to follow

  5. HCI Visionary Scenario Goals • Get students to feel like scientists • Expand technological capabilities • Enhance data gathering and distributing • Strive to be environmentally friendly and economically feasible • Enable all ages and those with disabilities to participate • Improve ease of use/maintenance • Enrich student’s learning experience

  6. Microscopes Ability to save pictures Output image to display Digital camera Capture images for memorabilia Handheld data recorder Record information to database Easy to use, efficient and interactive Feeling like Scientists: Tools

  7. Feeling like Scientists: Learning Aids • Displays • Convey learning information • Visualization for students • Database • Searchable, useful database for teachers, students, parents and others

  8. Feeling like Scientists: Memorabilia • Album • Picture examples of species found and identified • Class observations and findings • Photo of the students in action • Summary report for instructors • Class perceptions about river health before and after • Individual and class observations/findings • Website for all • Login and non-login options • Share experiences and observations

  9. Data Gathering and Distributing • All data digital • Students input data via handheld • Instructor validates data • Quick survey or automatic “flags” before sent to database • Wirelessly connectivity • Database automatically updates in real-time

  10. Environmentally Friendly and Economically Feasible • Green power source • Green fuel • Engine emissions • Modular furniture

  11. All Ages and those with Disabilities • Wheel-chair accessible • Adjustable height counters, microscopes, stools • Ensure good human flow • Accommodate large number of people • Allow movement to different areas (microscope lab, bird-watching, etc) • Audiences of all ages (kids/adults/elderly)

  12. Ease of use and Maintenance • Technology benefits • Eliminate need of paper • Manually inputting of data • Automation • Visualization of information • Instructors save time and effort • Data accurate and up-to-date

  13. Boat Demo • On Board team presenting live demo at 6pm on Voyager • Walks through Adam’s student perspective • Involves Adam’s friends, parents, school teacher and Voyager instructor • Demonstrates key components of visionary scenario • Each group plays role showcasing respective technology • Enrich student experience, assist Voyager instructors and improve on current processes

  14. Presentation Overview • HCI • Jonathan Pui • Green and Space Design • Sean Brennan • Handheld Devices • Thomas Boonsiri • Microscopes and Digital Camera • Jae-Kyung Lee • Scientific Data • Jackie Cheng • Wireless • Hassaan Moin Khan
