  • Ford North America announced international research collaboration with Prof. Michael Tsai’s research team

        Ford North America announcedtheir international researchcollaboration with Professor Hsin-Mu Michael Tsai's research team in the Dept. of  Computer Science and Information Engineering, National Taiwan University, in a joint press conference held in Taipei on October 21, 2015. The collaborative research project aims to eliminate traffic shockwave, a usual cause for traffic congestion, using the innovative vehicle-to-vehicle (V2V) visible light communications (VLC) technology, so that both vehicle energy efficiency and safety can be improved.

       Professor Tsai’s research team has been working in depth on the V2V VLC technology for the past few years. The main idea of the technology is very simple. The transmitting vehicle uses its LED light’s output intensity to represent different digital bit patterns to be transmitted. On the receiving vehicle, a light sensor is used to capture the change of light intensity, which is then decoded to retrieve the transmitted digital information. Conventionally, VLC receivers usually use dedicated and special-purposed light sensors, which introduces significant cost. Prof. Tsai’s team at NTU has developed an approach to utilize commodity cameras such as those in smartphones and tablets to capture and decode the signal transmitted by the LED lights, which avoids the use of costly sensors and lowers the barrier for bringing the technology to the market.

        When used for automotive purposes, VLC provides high reliability compared to Radio Freqeuncy (RF) wireless technologies, as it can avoid most interference generated by nearby vehicles due to visible light’s propagation properties – highly directional and (almost) line-of-sight only. Utilizing VLC between vehicles, drivers could have a more clear knowledge of the status of the preceding vehicle, such as its heading, speed, location, and whether the vehicle is braking, reducing the chance of a traffic accident. When coordinating the speed of the vehicles in the same lane, the technology could eliminate unnecessary variation of the distance between consecutive vehicles, which in turn increases the road capacity to avoid traffic congestion. Moreover, as the distance between vehicles can now be reduced without comprimising safety, the aerodynamic drag of the following vehicles can be greatly reduced, which creates new opportunities for energy savings.


         Thomas Fan, Chairman of Ford Lio Ho Motor Company (Ford’s Taiwanese subsidary), said, “Taking advantage of Taiwan’s strengths in hardware and software development, this new research collaboration can not only improves the driving experience on the roads in Taiwan, but is also instrumental in bootstraping Taiwan’s participation in developing global transportation solutions in the future.”

  • The User Experience Research Released Up-to-date Technologies in CHI 2015!

        The user experience research team (UX team) of Intel-NTU ConnectedContext Computing  Center attended the ACM annual conference on Computer-Human Interaction (CHI) 2015. Three research papers were published in the conference, including one honorable-mentioned paper. The researchers not only focus on developing latest technologies, but also conduct research to apply the innovation to users’ daily life.
    SoberDiary (

        Alcohol dependence is a chronic disorder. To abandon alcohol, patients will have to participate in a complicated follow-up maintenance programs, which helps them stop drinking. Is it really impossible to walk away from alcohol all by oneself? The Sober Diary team developes a new approach to this problem: patients now can stay sober with the help of their smartphones.
        With face recognition technology and a pluggable alcohol sensor, users only need to blow on the sensor, and the smartphone will tell if the users have been drinking. This mechanism makes recording and tracking users’ drinking habits easier, and simplifies the process of keeping a drinking diary. Visualizing the process of giving up drinking is another important factor of the success of Sober Diary. The storyboard of accomplishing the goal makes the patients realize that they are on the way to a grand goal: stop drinking. The visualized steps help patients obtain self-fulfillment within different stages of the treatment. Isn’t it wonderful?
        SoberDiary app turns your smartphone into the best assistant of alcohol withdrawal. Successfully assisting alcohol withdrawal in a long-term study, Sober Diary received Honorable Mentioned Paper award in CHI 2015, which is the honor of the top 5% paper in the conference. Dr. Chuang-wen You, the leader of  SoberDiary research, said:, “Like what Sober Diary tells the users when the goal is finally reached: we make a living by what we get, but make a life by what we give. We hope Sober Diary is not just an academic research, but rather an innovation to help those people and their family who are suffering from alcohol addiction.


    Cyclops (
        Imagine the new interaction brought by man having an extra eye. This is what the second paper presents - Cyclops. Cyclops is a single-piece wearable device that sees its user’s whole body postures from an ego-centric view of the user. The View is obtained via a fisheye lens put at the center of the user’s body, which is able to see only the user’s limbs and interpret his body postures effectively.
        Unlike currently available body gesture input systems that depend on external cameras or distributed motion sensors all over the user’s body, Cyclops is a single-piece wearable device that is worn as a pendant or a badge. The main idea proposed in this paper is the observation of limbs from a central location of the body. Owing to the ego-centric view, Cyclops turns posture recognition into a highly controllable computer vision. This paper demonstrates a proof-of-concept device and an algorithm for recognizing static and moving bodily gestures based on the past motion images and a random decision forest. With Cyclops, the complicated tasks can be accpomplished with a simple wearable camera, which provides a solution with higher efficiency and lower cost than the traditional approaches’.
        Dr. Liwei Chan, the leader of Cyclops research said, “Augmented human is a new research domain with the invention of wearable devices. With wearable devices containing small sensors and actuators, human’s physical abilities can be highly developed. The next step of Cyclops research is to installing cameras with various sizes onto different parts of human body, in order to provide more possibility of interaction and services.”

    WonderLens (

        Altough it is more comfortable to read and play with paper than with electronic displays, paper still plays an important role today. However, since the content printed on paper is static, it constrains the interactivity of printed paper. Hence, WonderLens presents a system of optical lenses and mirrors enabling tangible interactions on printed paper.
        When users perform spatial operations on the optical lenses and mirrors, they deform the visual content printed on paper, and thereby provide immediate dynamic visual and haptic feedback. The embedded magnetic unit of each lens and mirror allows them to be identified and tracked with an analog Hall-sensor grid that is placed behind the paper, so the system provides additional auditory and visual feedback through different levels of embodiment, and further allows printed paper to present dynamic information to users. This interactive system can be applied to board games, tangible learning applications, and playful interactions for children.
        “No matter how much digital devices replace or extend old technologies in our daily life,” said Dr. Rong-hao Liang, the leader of WonderLens research, and also the co-founder of GaussToys, “the interaction with paper is still unique and essential. We hope WonderLens is a step further to extend current imagination of paper and highlights new possibilities of paper with ubiquitous computation techniques.

Through 4-year  collaboration between Ministry of Science and Technology, National Taiwan University and Intel Corporation, the research outcomes of IoT and machine-to-machine (M2M) technology become mature and the preliminary research gradually become influential application to human life.
    The research demos in this year, our center emphasized more on automobile safety and home care. Moreover, we also expanded the M2M application to IOT of art and education. The research demos are included "Intelligent Transportation System", "Micro Piezoelectric Vibration Energy Harvesters and Its Interfacing Circuits", "IoT for Art" and "RollingLight: Enabling Line-of-Sight Light-to-Camera Communication", etc. 
    In addition, congradulating to Prof. Hsin-Mu Tsai, Prof. Ching-Ju Lin, Prof. Shao-Yi Chien and Dr. Chia-Han Lee of winning Intel Distinguished Collaborative Research Award in Intel Asia Innovation Summit 2014!

    Intelligent Transportation System
    In this project, our goal is to develop a proactive driver assistance system which includes 1) M2M-based neighbor map building, 2) driver behavior modeling and prediction, and 3) design of passive information visualization and proactive warning mechanism. To achieve these, we based on the structure of M2M technology to develop a function named Micro-Navigation to enhance intellihgent transportation system. The GPS system today provides main information of which road o drive or whether the drivers need to turn or not, etc. Furthmore, the Micro-Navigation provide further information to drivers about whether to change the lane, accelerate or reduce speed, or away from the specific dangerous cars. For example, exploiting machine learning and data mining models for ITS data analysis (e.g. red-light runner detection, driven aggressiveness classification, aggressive turn detection) in order to achieve the multiple goals of  safety and oil safeness.
    Distributed Video Cameras
    Other than distributed video coding, we will also pay more attention on distributed video analysis. For distributed video coding, our goal is to develop the state-of-the-art and practical DVC, including multi-resolution/multi-view DVC and HEVC/H.265 based DVC. We plan to define an API that can be used to implement video applications on distributed video sensors and develop the associated hardware video analysis engine for distributed video sensors. The sensor configurations can also be selected with the control interface to achieve a good balance between power consumption and recognition performance. Before the end of this project, these techniques will be implemented in an FPGA system as well as chip tape-out. The developed system will finally be deployed for selected real applications.
    Micro Piezoelectric Vibration Energy Harvesters and Its Interfacing Circuits

    We have introduced self-powered synchronous switches in to the interfacing circuit, but find the voltage requirement quite high and the energy loss of the rectifying circuit is considerable in low power occasions. To solve the interface circuit loss problem, we propose a three-phase solution. Firstly, models of discrete components are analyzed. In the same time, experiments using discrete components are performed to discrete realistic occasions. Then, dominant characteristics of the components that determine the loss are specified. In the end of this stage, we should be able to choose appropriate discrete components to proof the best efficiency. Finally, integrated circuit based on CMOS can be designed and conducted. The ultimate device should be able to be packaged in an IC package, i.e., ball grid packaging. We also aim to reduce the resonance frequency value to meet the requirements of wearable energy harvesting devices. Hence we have searched for polymers and other possible structures to eliminate the operating frequency. The device design for wearable energy is our ultimate goal. 
    IoT for Art

    IoT for art demos the possibility of integrate smart devices to perform art activities. Showed two examples as belows. One is the Smiling Buddha, an interactive art installatio, which enables users to exchange their smile to the portraits on the display wall. The other is the Dance Man which enables users to draw their avatars independent and eventually make them to dance together on a combined display.
    In the display, we encouraged people in all ages to draw pictures on smart devices. Through the M2M information exchanges, all smart devices can be integrated into a combined display. Users can produce mudic and make the pictures dancing with. Those pictures can interaction over the limitation of each screen. The application could accelerate the imagination of M2M.
    RollingLight - Universal Camera Communications for Single LED

    RollingLight - Universal Camera Communications for Single LED, that enables a light to talk to diverse off-the-shelf rolling shutter cameras. To boost the data rate and enhance reliability, RollingLight addresses the following practical challenges. First, its demodulation algorithm allows cameras with heterogeneous sampling rates to accurately decode high-order frequency modulation in realtime. Second, it incorporates a number of designs to resolve the issues caused by inherently unsynchronized lightto-camera channels. The technoligy can be applied in localization to increase the accuracy while driving to enchance automobile safety.
