Other Java JDK 7u13 JRE also worked Google Earth 7 1 Desktop version Wave audio file other audio formats are not tested 15 Appendix B Hardware Cost Displays Several display types were evaluated The project requires that the student have displays in front and on both sides in order to simulate an aircraft cockpit The displays that represent the side windows should be as close as possible to a 90 degree angle in respect to the front display The first evaluation was a curved glass display that Samsung Corning is still trying to design The display is not ready for market yet so far all they have is a small transparent screen that they are showing at trade shows Another type of display is a curved projection screen We were not able to find a screen with a listed price of under 15 000 Also the screens won t surround the students on three sides they only have about 20 degrees of curve The third option was multiple 60 inch monitors with one screen in front and one to either side of the students There are two ways to drive the monitor the first is with graphics expansion module that splits the video display across three screens The second is to use three separate video adapters in the host computer The expansion module is the least expensive solution and is the best choice if Google Earth does not offer separate side views A note about 60 inch monitors they don t accept VGA or DVI computer signals they only a2. of the earth is seen as a straight line And on the drawing notice that the far displays dont face each other The horizontal Field of View at the ends of the screen is 180 degrees The perceived distortion goes away as the viewer gets closer to the screen If only three screens were used around the arc then the distortion would be overwhelming at any distance Also the angle between each display would be about 60 degrees and the rear ends of the arc would not look realistic If seven screens for 180 degrees are used then there is a small amount of improvement but it is not worth the extra cost The following graph shows that improvements to the horizontal Field of View start to drop after 5 screens around a 180 degree arc Number of screens Angle between screens 60 5 36 5 25 5 20 5 16 5 Why not use 36 0 degree angles and what is the extra half degree for There is no documented answer to that question An assumption is that the half degree accounts for the width of the display s bezel KML When developing code for use with Google Earth typical programing languages would not work due to the lack of spatial data needed to interact with two dimensional and three dimensional maps So to solve this lack of support Google developed the Keyhole Markup Language or better known as KML KML is an XML based language that details geographic data and allows for the inclusion of points lines images polygons and models to be

7. controls and student activity JQuery and JavaScript were originally the languages that were proposed for this project With our beginning idea the thought to use the Browser version of Google Earth was decided but later changed due to the understanding of the KML language To use the KML files which store the lesson plans and description a desktop application of Google Earth would need to be run Because of this the use of two web based languages did not fit our design This is the reason that java was selected for the final languages used 12 Results This project has been tested on Windows XP Windows 7 and Windows 8 and worked well on all three but java JAR files do not run on computers that were provided for the simulation The problem was corrected when the computers were upgraded to Windows 7 To date the functional requirements have passed tests on the development computers and our XP test computer At one point during the demonstration we showed one of the teachers how to create an example lesson with various features and he was comfortable with the structure and had a good understanding of the mechanism under the system A detailed document is provided to make sure future users are clear on what to do We also showed the client the main program interfacing between users and Google Earth They agreed that the program is user friendly and easy to understand In addition the program covered exactly what they want and they r

They have been very successful with their mission to educate the students but could use another tool to further excite the students and engage them in learning The principal Troy Braley has developed an idea to use Google Earth in a flight simulator type setup to allow the students to explore the world and foster a desire to continue learning and coming to school The client has also requested the aid from the educators that will be using the program and has had them develop ideas and functionality requests for the project Product Vision The Brady GeoPod is for Brady High School who need for a way to capture the student s attention and promote staying in school while delivering a system that allows the students to learn and experience social science classes in a fun and exciting way The Brady GeoPod will utilize Google Earth to allow the students to explore the Earth in various places and allow them to enjoy the learning process though the program and technology The GeoPod will allow the educators of various classes to develop interactive lessons that engage the student as well as creating a positive learning environment for the students through the use of the Google Earth implementation The students and educators will also have access to a control panel to assist in controlling the software and also features that can be used to facilitate the students learning and interest in education Requirements Functional Requirements The Geo
