    Path-Guide is a scalable navigation system, which uses peer to peer navigation as incentives to collect indoor traces and reconstructs the indoor trace map by concatenating different trace segments. Combining traditional signal processing and machine learning techniques, I designed a model to rearrange the segments in different traces and cast them into indoor maps. Based on this research, we developed a general commercial indoor navigation system, making indoor navigation see its future of getting wide development for the first time.

    MPTCP-based Security protocol

    Advisor: Chenren Xu

    MPTLSLite is a ”lightweight” data security mechanism dedicated for MPTCP to reduce the protocol overhead on negotiation and computational cost in the mobile environment. With multiple independent transmissions, MPTLSLite can generate session key with only local hashing computation rather than legacy SSL handshakes and RSA encryption.

    Software-defined QR-code

    Advisor: Kaigui Bian

    Software-defined QR-Code system is a system aims to endow intrinsic flexibility to QR-Code. The protocol splits the QR-Code into two parts, the static templates and dynamic decoding rules. By overriding the decoding interface we provided, the programmer can define their own decoding rules. This project has seen its future application on check-in and mobile payment.


    Advisor: Kaigui Bian

    looking into my eyes (LIME) is a system that can measure the distance between users' face and smartphone screen without any auxiliary devices. I proposed a fine grained method to estimate the screen-face distance by measuring the user’s interpupillary distance in the photo taken by front camera.

    Urban Analytics

    Advisor: Jason Hong

    Urban Analytics is a project that evaluates the neighborhoods of a city by analyzing geo-tagged tweets. By combining analysis on both topic and sentiment domain, I was able to extract the features of different neighborhood in Pittsburgh.
