5. Topic this year Interactive Virtual Aquarium 5 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun Picture extracted from www.dreamaquarium.com

6. 6 Topic this year (cont) Interactive Virtual Aquarium ABC Software Company would like to develop a new software called – Interactive Virtual Aquarium Use 3D graphics to reproduce an aquarium on a computer The swimming fishes and other inhabitants are rendered in real time Although those creatures are not real, they should do everything that real ones do Pecking at objects in the tank, eating food, chasing each other, swimming amongst the plants, or even fighting with each others! Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

7. 7 Topic this year (cont) My Virtual Aquarium Different from the current virtual aquarium in the market, ABC Company would like to introduce the following two features: The growth and behavior of the living creatures in the virtual aquarium should follow a time function (just like tamagotchi!) E.g. the fishes will grow-up, change size and shape, and die as time goes by E.g. the tank will get dirty if not cleaned regularly in time The virtual aquarium will interact with the user based on his/her body motion Achieve by using a Kinect sensor device – a motion sensing input device created by Microsoft Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

8. 8 Architecture of the Interactive Virtual Aquarium System USB port 3D Graphics System 3D Graphics Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun Your program Your program Network Computer A Computer B Kinect Sensor Device

9. Tasks to be achieved in this project Each team is provided with a Kinect Sensor Device Carry out the following tasks Collect the information of real fishes and other inhabitants of an aquarium Based on such information, develop their graphics and animation Design the interaction between them and the player Implement such interaction by making use of the Kinect Sensor Device to detect the body motion of the player Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun Kinect Sensor Device

10. Tasks to be achieved in this project (cont) Not only technical tasks, but also non-technical task Each group needs to make a study on the behavior of fishes and other inhabitants in aquarium Nowadays, the success of an IT application is not only due to its technical excellence, but also if they are “liked” by the users – very often due to non-technical reasons E.g. Apple’s iPhone vs Nokia N9000 smartphone 10 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun Which one is more success? Why?

11. Tasks to be achieved in this project (cont) More example: The success of the XBox car racing game Project Gotham Racing is not only due to its graphics or interactivity, but also the incorporation of the real scenes of over 12 car racing tracks in 4 cities in the world Nowadays, software designers, particularly those in the IT area, put great effort in contents design, which often determines if their software is successful or not 11 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

Introduction by Dr Daniel Lun

22. 22 Why project management? A project involves the interaction of different parties A project will be successful only if all parties do their job right By having good project management, we can Achieve the project goal on time and within the budget Keep your boss and your customers happy Keep the team focus on the goal and work well Everyone shares the load Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

23. 23 Project Management Project Planning and Implementation Define objectives / requirements Define work/tasks Identify resources Plan schedule Iterate Plan modification Execution Management Get objective signed-off Track plan progress Communicate within team Customer communications Secure resources Project discipline TechnicalPeople Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

24. 24 Project Planning The process of project development is full of uncertainties The more uncertainties you have, the less possible that the project can be successful Uncertainties can be reduced by having a good feasibility study before the project Background research Understand the resource required and acquired Risk analysis The feasibility study has been prepared for you in the lab exercises Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

25. 25 Requirement Analysis The purpose is to identify and document the exact requirements for the project Much interaction must take place between the customer (e.g. Professor) and the developer (e.g. students) Should be well documented since very often it serves as an agreement of the functions that will be provided by the system developed The document is sometimes called user specifications or functional specifications May form the basis for project commissioning Your proposal should contain the above items Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

26. 26 System design and specification Split into two sub-phases: architectural and detailed design Architectural design Define the overall organization of the system in terms of high- level components and their interaction Detailed design Lower level modules in each component and their interfaces Example: In software development Architectural design – the function and relationship of classes Detailed design – the internal modules and interfaces of each class Should be well documented The document is sometimes called technical specifications Your proposal should contain the above items Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

27. 27 Implementation – Work breakdown Split project into tasks and estimate time and resources required to complete each task Organize tasks concurrently to make optimal use of workforce Minimize task dependencies to avoid delays caused by one task waiting for another to complete Should be detailed in the proposal and final report Department of ELECTRONIC AND INFORMATION ENGINEERING 1.

Introduction by Dr Daniel Lun Need to give evidence in the final report to prove your team has followed them when implementing your project

30. 30 Wrong Concepts and Bad Practices For students who are new in doing projects, they often have the following wrong concepts and bad practices: “We will not be able to finish the project since all techniques required are new to me.” It is exactly the kind of training we need you to go thru. Learning to learn is one of the most important parts of a project. In reality, it is very often you are asked to do something you don’t know. Only those who can learn faster than the others can win in the society Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

31. Wrong Concepts and Bad Practices (cont) “We didn’t allocate task to members since we work together all the time.” A very bad practice. It means that there is no teamwork among members. To avoid you doing this, each member of the team will be given a different task. The results of all team members should be combined to accomplish the project objective. 31 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

32. Wrong Concepts and Bad Practices (cont) “My team member didn’t do anything. I decided to leave him alone. The work submitted was done by me.” See, finding suitable partner is very important. That team member certainly will fail, since team members will be individually assessed. The marks of the team in project management (in particular teamwork) will also be deducted. 32 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

33. Wrong Concepts and Bad Practices (cont) “Our team was very busy in many different things so we skipped all the tutorials, lab works and demos. But we managed to use the last few days to finish everything and made a good demo of our game in the Final Demo.” Assume that you are doing this project for your customer. If I were the customer of your project, I would never hire your team to do project again! All customers want to see both progress and result. So your marks in project management will be deducted. 33 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

34. Wrong Concepts and Bad Practices (cont) “Time is limited in doing this project. If I have more time, I can do it much better.” It is exactly the objective of the subject to provide training to students on time management. Bear in mind that the subject does not ask you to achieve a perfect result, but a satisfactory result within a time limit. Only those who have good time management skill can get good grade in this subject. 34 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

35. 35 Some Advices on Problem Solving People like to solve problem based on its symptom and try to remove the symptom Following the philosophy of western medicine, if you have headache, you will be given a Panadol to remove the headache It works sometimes but not always. Sometimes removing the symptom may just let the real problem (can be big problem) unable to be discovered Have we ever taken time to think of the reason behind the problem and try to really solve it? Sometimes you can find out the reason, sometimes you cannot But it is still worth a try Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun

36. Some Advices on Problem Solving (cont) 36 Department of ELECTRONIC AND INFORMATION ENGINEERING 1. Introduction by Dr Daniel Lun When finding the reasons of a problem, don’t ignore any small abnormality in the course of project development Particularly in software development, even a small bug can bite you hardly, and perhaps at the most crucial time! Of course, if there is no hope to solve the problems, looking for tricks to get around them is still a good solution
