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

Feeling like Scientists: Tools 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

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

Data Visualization: Real-Time Graphs Day’s activities to be displayed on LCD

Displays overall results by station

Web interface

Easily navigated by teachers

Utilizes PHP scripts to query database and dynamically generate graphs

Constantly refreshing / querying database

70

Real-Time Screenshot (Overall)

Dynamically generated graphs can show types of samples found (i.e. pollution tolerant / intolerant macro samples)

71

Data Visualization: Water Quality Analysis User defined graphs of historical water quality reading

User chooses: River and water quality attribute to be analyzed

User specifies the date range for the analysis PHP scripts take these selections as their input and query

the relevant data from the database Results are fed into a PHP graphics library to create a line

plot of the samples over the specified time Important statistics such as sample mean, standard

deviation, minimum and maximum are also calculated and displayed
