Report For Let's Live 3D

  1. 1. LET’S LIVE 3D DESIGN (LL3D) Muhammad Nur Thaqif Md Rajab Johor thaqif_rajab@yahoo.com Aminah Mustaffa Labuan Aminahmin94@gmail.com Tg. Shamimi Dahlia Tg. Shaiful Anuar Terengganu Sharmin1006@gamil.com Harnasyrin Afiqah Hakimi Negeri Sembilan Ayinrain94@gmail.com INTRODUCTION Senorsenoritas is a group formed by four which are Aminah Binti Mustaffa, Tengku Shamimi Dahlia Binti Tengku Shaiful Anuar, Muhammad Nur Thaqif Bin Md. Rajab and Harnasyrin Afiqah Binti Hakimi. We are second year Computer Science students majoring in Bioinformatics. For Human Computer Interaction (HCI) project, we are required to develop an application based on our own design and implementation. In this project, our roles are as follow :  Thaqif – Project Manager  Shamimi – Project Manager Assistant  Aminah – Data Administrator  Harnasyrin – Application Designer PROBLEM STATEMENT Try to imagine when we want to design something, like clothes or a cartoon character, or even something larger such as designing a house. Firstly, we need to sketch the design into a piece of paper and after that we will construct the real thing. So, this is where the problem comes, what if we doesn’t like what we have built? As a result, we need to start all over again and trash out the older design. Therefore, this kind of traditional method of designing and bring the design into reality costs us a lot of time and money if something ever goes wrong in the method. TARGET USERS Our target users are everyone that are creative and able to create something out of their own creativity. However, this application are likely to be used by designers out there, no matter which field they came from, such as fashion or architecture or even the freelancers. PERSONAS Inah Allia Solehah is 12 years old child. She likes to spend her time with sketching. When done with sketching, she likes to apply the sketch to a drawing software. However, she is tired of the complicated software and it is hard to understand how to use it. Tanner Patrick is final year of graphic student. He loves to play games online. He hopes that one day he can develop his own game with a high quality graphic interface. At this time, he really needs of a software that can help him in designing the game, especially in designing the characters. He wants the characters to be in three-dimension state so that they look more real and alive. Muhammad Sabarudin bin Yusuf is 25 years old working as an architect. He just started his career in a big company. He is currently searching software that have 3D features so that he can present his proposal more realistic to his client. 23 years old Sabariah Binti Muhammad Nur Thaqif is an Art teacher in high school. She wants to produce a colorful drawing sample that could help her with her teaching in class. However, she still could not find any software that can satisfy her expectations on the coloring method. TASK SCENARIOS Inah is a 12 years old kid who likes to sketch and draw comic. Then, she found a new software to help her drawing her comic. However, the manual is difficult to understand and the interface is too crowded . She hope that she can find a software that has simple interface with understanding manual and thus, would satisfy her expectations. Tanner Patrick is a graphic student. He has an assignment which is to develop a game. Before designing the computerized game’s character, basically he needs to sketch on paper first, then he will need to draw again using the software. This method is quite difficult and consumes a lot of time to complete as he’ll need many steps to be done in order to finish designing the characters. He want a software, that would make it easier for him in creating 3D characters for his game which could also providing various choices of 3d shapes so that he can just pick any shapes that he wanted and drag it to the design. Sabarudin is an architect in a big company. He needs to prepare his model plan and his project’s blueprint for the project he’s assigned with. Usually, he will bring his blueprint to present the project to his team or clients. However, this old fashion style is not efficient, as they cannot review in more realistic features.
  2. 2. A problem also occurred before he starts to work on the real prototype. He wants to make sure that there will be no small mistakes on his design so that when he working on the real prototype there will be no problem or errors. He needs a software or hardware that can help him to detect any mistakes where he can re-edit the design. He also would love any software that can save his budget and time. Sabariah is an art teacher in high school. In teaching her students arts, she demands the students to colorize the drawings creatively. The student can choose either to paint the drawings traditionally or a modern way which is using a computer software. The students prefer the traditional way because they cannot find any suitable software, but the problem is good qualities of brushes and paints are quite expensive and they need to replace them with new ones if they’re already worn out. Furthermore, the traditional method needs a lot of time and the drawings made are not long lasting. Hence, she needs software to be promoted to her students so they can apply the modern way in coloring the drawings. SOLUTION To all designers out there, no more worries on design failures! We are introducing an application that will serve you a detailed design of yours before it is realized. Let’s Live-3D Design (LL3D) - is an application that allow us to create or sketch using wide choice of selection by touch. You also may design on the screen using a stylus on a nice-flow LCD screen with a fast detection of your drawings on the screen itself! Wait, there’s more! LL3D also can bring out the virtual design into live atmosphere where you can interact with the virtual design using your bare-hands and off-screen! LL3D will make it easy for you for editing or reconstruct a previously a bad design. This application will enhance your experience in designing due to the multiple ways of interacting with it; touch and air-based gesture. You need perfect designs, you need creativity, you will need Lets Live-3D Design! CONCEPTUAL DESIGN The figure below shows the flow in our conceptual design which include all the tasks that users can fulfill when using the LL3D application. Figure 1 Conceptual Flow Diagram DESIGN In designing the application interface, we have come out with few results of sketches so we can compare them with one another and come out with best design idea for LL3D. LL3D is a composer used for designing which have many functions that users can use. Therefore, the design must be simple for user to understand every function that exists in the application. Hence, making LL3D is user friendly. Some of the important features that we need to add up to our application design is the app drawing tools (pencil, lines, pen, brush, etc. ) and the 3D related features.
  3. 3. Figure 2 : First Design Sketch Figure 3 (a): Second Design Sketch Figure 3 (b): Second Design Sketch Figure 4 : Third Design Sketch Figure 5 : Fourth Design Sketch
  4. 4. Figure 6 : Final Design Sketch Figure 6 shows the final design sketch that we finally decided to make it as our paper prototype. See: https://www.youtube.com/watch?v=4zujNYgsTmY After the paper prototype, we proceed with the same design and build the computer prototype with just a little adjustment from the actual design. Figure 7 : Computer Prototype Main Screen Figure 8 : Computer Prototype (Tutorial) Figure 9 : Computer Prototype Workspace Figure 7, Figure 8 and Figure 9 shows the computerized LL3D interfaces. As you can see, we tried to keep the design as simple as we could, but still trying make it attractive for users.
  5. 5. Figure 10: Computer Prototype Go 3D In Figure 10, it shows the 3D mode, where users can interact with the designed 3D objects. The 3D button function is to switch between editing mode and 3D mode. Meanwhile, the red buttons above add up users’ interactivity with the object. IMPLEMENTATION We have decided to create an application based on two types of interfaces which are; touch and air-based gesture. Therefore, in designing an application that would satisfy those two interface types would be a little bit tough for Senorsenoritas and we really need to think out of the box. Hence, we come out an idea to create a designing application which is kind of a common application we would have come across in our normal days. Therefore, in making our application different with other designing apps, we add on the 3d features to it. Thus, making LL3D becomes more interesting. LL3D have various choices for user to use or in editing the 3D object. In implementing the LL3D functions, we need a software that also support 3D features in creating the LL3D computer prototype. Using Intuiface software, we implement various function to this application which includes drawing, types of strokes in drawing, default sides button for 3D objects ( Left side, Right side, Top, etc. ), zoom in and out, supporting the color strokes and many more. However, at first we encountered a problem on how are we going to add a live three-dimension object to our computer prototype. We are only able to show different sides of object, in two-dimension and therefore the 3D requirement is not fulfilled. Then, we solve the problem by basically implement the example that we used in our paper prototype, a 3D house object. Using the help of internet, we downloaded a few sample of 3D objects and try to test it on our computer prototype. Next, implementing the default sides button, we need to find the correct x-axis, y-axis and z-axis to make the 3D object rotates to user’s choosen sides. For example, in making the 3D object rotates to its front side, we need to set the x, y and z axises to 180,0 and 180 respectively. The other functions are implemented easily using the software. Basically, if user touched/clicked on a button, we use a popup textbox that would suggest the user more choices that the user could pick and use it on the canvas or the 3D object. On the other hand, implementing the 3D projector as part of our prototype we only managed to make a fake projector and make it able to project some lights out of it and make a 3D object out of papers to show the users the idea on what LL3D could do using the air-based gesture features. We recorded a video to show users how the 3D object would react to hand movements in live surroundings. EVALUATION For the evaluating process, we have created our own questionnaires and spread it to the community to get the feedback based on our application. Resulting in 40 respondents that had respond the questions about LL3D and then we analyze for every single result based on their responses. Furthermore, for the User Acceptance Testing (UAT) session, we have chosen 4 different users, in the level of beginners, to have a go and try to use our application and we have recorded the time taken for each user to complete all the task given during the test. We have learned that, in creating an application, it is necessary to fulfill the users’ needs and requirements. Figure 11 : Question 1 Based on the pie chart , we can see that 93% of respondents which is 37 out of 40 find that LL3D is interesting. On the other hand, only 7% of them said it was not interesting.
  6. 6. Figure 12 : Question 2 83% of respondents (33 out of 40) understand the instruction or given steps to use the application. Meanwhile, the other 18% of them have no idea how to use it. This shows that the given instructions were quite easy and understandable. Figure 13 : Question 3 In rating the attractiveness of the application’s interface, 8 out of 40 (20 respondents) give 9 which is stating the interface is almost very good. Meanwhile, the percentage of respondents that chose 4, 7 and 10 are all 18% respectively. The varieties of user’s rating maybe depends on the users themselves to find whether the interface looked good or not. Figure 14 : Question 4 The question was on about whether the application is boring to use or not. Therefore, the pie chart shows 80% of respondents answered No meanwhile the remaining 20% said Yes. This proves that LL3D can be an enjoyable experience for some users. Improvements can be made to ensure that the percentage of respondents that said No could be lessen in adding up more fun interactivity and users flexibility in using LL3D. Figure 15 : Question 5 The bar chart shows that majorities of respondents rate the efficiency of LL3D with 7. This can be considered as optimum efficiency expectation of LL3D. On the other hand, minorities rated with a 1 and 7 out of 40 respondents rated with 10, stating that the application is very efficient. Therefore, the results indicates LL3D can be counted an efficient applications. Figure 16 : Question 6 We have tested the user’s preference whether to use the application on desktop or on their smart phone. Most of the ( 27 out of 40) chose desktop meanwhile the other 13 chose smart phone. LL3D application is a software that are only fit to be use on desktop for now. However, we need to reconsider about making this application comfortable in mobile/ smart phone.
  7. 7. Figure 17 : Question 7 On the responds on about the 3D functioning projector , 85% of respondents opined it is exciting and interesting to be use while 4 out of 40 responds are their do not really understand its purpose. 3D functioning projector is something that quite rare in Asian technology market, hence many people would find it exciting yet few of them could not understand what 3D projector could do. Figure 18 : Question 8 From the analysis, we find that 33% of respondents which is 13 out of 40, confuse on how the application works, while 65% of them that is 27 out of 40 did not. This shows that bigger number of them don’t have any problem on understanding on how LL3D works. However, there are still few left behind, confuse on what is LL3D all about. Therefore, we need to provide them with a better help or guideline to ensure that every user would fully acknowledge how this applications run. Figure 19 : Question 9 Analyzing the pie chart above, 30 respondents out of 40 said Yes, agreeing that the tutorial given is enough for them to understand this usage for each function in the application. Meanwhile, another 10 responses are not. This indicates the tutorial given is not clear enough as some of the respondents (25% of them) said no, and therefore, the tutorial method in our application need an improvements. Figure 20 : Question 10 In comparing LL3D with other design applications, 65% of respondents which is 26 out of 40, state that LL3D is a lot simple but is more interesting. Meanwhile, the least percentage is only 8%, which state the application is more complex and the function are hard to be understood. There is also one single other opinion given by a respondent which said the application is “good enough”. For the other two choices have acquired the same percentage of respondents which is 13%. Figure 21 : Question 11 In rating the application from 1 to 10 ( low to high) , 25% of them rate LL3D with 10 while the least rating which is 1 only required 3% of responses. The rating of 7 and 8 retrieved a same amount of respondents’ percentage which is 15%. Plus, 18% of them rate the application with 9. This show that the majority of people give high rating for LL3D and therefore this application satisfy them.
  8. 8. REFLECTION According to our project that we have completed, we have learned a lot of things from it. For example, in developing team building skills is an important benefit for our learning process and our progress in this project. It was not always easy developing an effective team, therefore a full commitment is very important in working as a group. Our team will make discussion regularly when we have any tasks that were given by our lecturer. During each meeting and discussion, we have shared our ideas and our understanding about the task given thus, this sharing of each ideas will help us to achieve the best result. The major benefit of working in a team was that we facilitated and enhanced our own understanding of the projects. In designing process, we have list all of our ideas and knowledge on how to design the interface for our projects, and then we choose the best idea to take it into the implementation process. Furthermore, for every task given we need to be well- planned before we start to do any sketching or building the application. Moreover, we also discovered and learn how to make real computer prototype using the available software such as Intuiface. Henceforth, the analyzation method and process is quite important to ensure whether the application is truly accepted amongst various type of users. Finally, from the evaluations taken we have learned to make further improvement to the application we are developing so the requirements that were not fulfilled before is reviewed and added into the application function. We hoped that in the future, Senorsenoritas team can develop a better and more reliable application for the community.
