Q1: congratulations couple mobile project in MobiSys2007 on best project award presentation, to give us a brief description of this technology?
A1: I just received another good news, we recently held a Conference on also won SenSys2007 a best presentation award, this Demo is the precise location of the phone, the idea comes from couples cell phone project.
Incidentally, SenSys is the area of wireless sensor networks, our top conference papers from mainland China is the second article. Next, I introduce the lovers on a phone. We do mobile project in the first place is to software and system framework to improve the use mobile phones, rather than the current performance of universal practices such as increasing mobile hardware specifications, such as CPU clock speed, Memory, etc. However, we note that most mobile phones now, so here we want to do more than one phone number to others didn't think of cool things, such as shared between different mobile phone data and resources, and so on. Because now mobile video comparison of the fire, we'll do a video sharing application. We are very pleased to have recognition. For now, this project has a huge market potential, we have received from the manufacturer's development and cooperation's intention and invitation. About the exact location of mobile phone Demo, in that project, I found that we encounter a new problem, that is, the distance between the mobile phone, because we want to know the distance can be synchronized.(Shen Guo bin, researchers at Microsoft technical section on display lover¡¯s phone, pictures Xinhua Qi hang shooting)
Q2: for lovers of the entire development process, you have the kind of experience to share?
A2: first, I think don't overlook a small Idea, lovers of inspiration on the mobile phone from the discovery of life.
Once out my cell phone is dead, but this time who phone has abundant power, then I think whether two cell phones can share some resources, such as power, etc. In addition a mobile phone's screen size is limited, if several mobile phone together, on the rational utilization of our resources is very good. This idea may be small, but caught up again after it found very interesting. Another example of our best SenSys papers and presentations are due to lovers of demand for mobile phone: we need to know the exact distance between the mobile phone in order to determine whether two cell phones put together. This is actually a very difficult question. We have adopted a relatively new method, using the sound card sampling frequency neatly solves this problem, we can achieve accuracy of 1 cm, and the world's other method can do the best we can only achieve 5 cm. Second, ask questions and find answers to important than, timely communication and Exchange is more important. Have an idea you want to say it in a timely manner and others share discussions, others will give you the idea put forward more to the point of view, it is beneficial to take to resolve problems more clearer. Our research group seminars I benefited from.Q3: you have until September 2005, has been engaged in a video image processing fields, what makes you go in another direction: wireless sensor networks and mobile systems?
A3: there are two reasons.
On the one hand, on the basis of the Institute of development, need me to do some research in this field. Another more important reason is that I am very interested in the topic. I think good research directions should be those that have a big impact and has great potential. The current global sold almost 40 million mobile phones, can make some results above is very meaningful. Of course, to do research on the mobile phone is very challenging. In fact, the average of the researcher in 5-7 years will consider changing to a new area of research. However most of the researchers the conversion of research areas are interrelated, span also is not very big. In fact, I used the phone lovers do multimedia areas is associated.Q4: for a new direction, how do you begin to study, and in this area make good grades?
A4: I want to say that basic research method for every field is the same.
First of all, on their own to study for a full investigation. Secondly, to extensive reading the papers in the field of high level, find the entry point of interest. Once again, to painstaking research, avoid irritability. Many researchers have just go to aNew areas always want fast results, in fact, the correct approach is to their own ideas to make a good assessment, find a pointcut perseveringly study continue to be made in the study.Q5: for your students, you have special instructions?
A5: when I was in junior high school has been an experience, then because not too fond of the math teacher, resist not studied mathematics, results in a race that year before research in mathematics for 40 minutes.
Good in front of the entrance examination, once I figured out a good solution to a problem, get the teacher's highly praised, from which I have been very good in mathematics. Of course, this example is not worth learning, but from there I found on students to more motivation, so that they will have the confidence to do better. First of all, I rarely criticize my pupils, as far as possible encourage method. Although sometimes harsh, but there is something wrong. Secondly, I will often communicate with students, I will give each student schedule weekly 1 on 1 discussion face-to-face information and solve problems. We also have group meetings, study groups often communicate on a regular basis. I also encourage my students and I chat, not only on the work of things so that students can learn more as people engage in scholarship, for students of development is very useful. But I do the same.Q6: do research or planning for the future, do you have any suggestions for interns?
A6: first of all I think the plan is better change fast, one cannot be nothing planned.
You can plan, but not too fine, usually as long as you have a large scope of his love on the line, such as determining whether to go away for academic finance roads. Secondly, to determine what exactly his own interest, currently the subject of you do not look too heavy, interest can be changed. It is important to lay emphasis on basic skills, usually of accumulation. To adapt to changes, in time for possible changes.
