1. Acknowledgement smartBoard will not be able to succeed if we were lack of the invaluable resources knowledge and the workplace whose is given from our Kasetsart University And SmartBoard also has been taken care of by Asst Prof Ph D Jittat Fakcharoenphol as a project advisor We would like to thank you for your great suggestion ideas and advice which can keep our projects main point of view stable and obvious for the past of the time However SmartBoard cannot achieve the most completed develooment point without the assistance from National Electronics and Computer Technology Center NECTEC which including funds recommendation and also the significant opportunity given to us to be one of the challenger of the Nation Software Contest NSC 2007 Finally we re deeply indebted to by Asst Prof Ph D Jittat Fakcharoenphol a project advisor who spent his valuable time to re organize our work analyze the results and teaching us everything which couldn t be given from the others as well Best Regards SmartBoard Team Report Manipulator 03 January 20082. q Y a a A a Y AJA A Y A a a Y a Al a v q Our team was together to develop the 3D Game online called Magic Isla on oN year semester We are familiar with working in group and if we re back to develop the new project again it will easier for us to communicate break down the tasks and understand the work content in order to achieve same goal Nowadays World is competing all the time and highly increased So each huge company has to develop adapt or enhance in order to maximize the profit and avoid the bankrupt This makes their software they re using more complex and increasing in size If we have a team with better development process appropriate communication and management it will be the important factor to success in building the effectively software according to the timeline and resources So this is the reason why we pr

4. Smart board LAZ ABSTRACT Smart Board was created to enhance Physics education in Thailand We think that motions of objects and graphs of object motions can help high school students to understand Physics and have good attitude toward Physics Moreover this program increases Physics knowledge in an elementary school Elementary student will gain basic Physics from drawing and motion of objects Process of Smart board this program will recognize a free hand drawing picture drawn by student in its drawing frame and after a student press a play button program will simulate motions and graphs which respect to the law of mo

10. efer to working in team The motivation we choose this project is right now Thai students especially feel perplexed about physics a necessary subject in high school because they cannot imagine motions of object in a physical problem For example a big ball hits the other smaller and lighter ball Some students are not able to imagine a motion of both balls Therefore a physical simulation program can assist them to study the Physics because the student can see a simulated motion in a computer screen and understand a physical situation better If the students understand the Physics they will be inspired to study it in higher education Table of Contents Pages Chapter 1 Objective 1 Chapter 2 Graphic User Interface 2 Iteration 1 2 Main Menu and Toolbar 3 Main Property window 5 GUI Structure 8 New design GUI in SmartBoard application 8 Menu Option Component 10 Icon Menu Structure 11 Icon enlarge 12 Component in each Menu Option 13 Template 16 Properties Menu Option 19 Change in new design for property frame 22 Shortcut Component 23 Chapter 3 Functional Algorithm 24 Functional Algorithm Topics 24 Line Cutting Algorithm 26 Close Shape Detection Algorithm 28 Sort Point2D in clockwise 29 Transformation 30 Physic simulation control 33 Shape Description 34 Shape Intersection 35 Fix Joint 36 Basic Joint 36 Undo and Redo function 37 Spring selection area function
