Projects

  • GroupNotes: Integrating Textual Annotations into Multidimensional Visual Dashboards

    GroupNotes: Integrating Textual Annotations into Multidimensional Visual Dashboards

    Human-Computer Interaction Lab, UMCP

    We explore an adaptive annotation technique called GroupNotes for presenting annotations, which are associated with subsets of the dataset, on top of any visualization irrespective of the scale of data shown or the design of visual representation itself by grouping and ordering textual annotations.

  • Supporting Team-First Visual Analytics through Group Activity Representations

    Supporting Team-First Visual Analytics through Group Activity Representations

    Human-Computer Interaction Lab, UMCP

    We achieve group awareness by collecting the state of each analyst’s exploration and then representing the common state using both (1) in-situ which shows the focus regions of all users integrated in the visualizations themselves using color-coded selection shadows, as well as (2) ex-situ showing the data coverage of each analyst using a parallel coordinate plot or a scatterplot.

  • Exploring Linguistic Signal for Schizophrenia

    Exploring Linguistic Signal for Schizophrenia

    Computational Linguistics and Information Processing (CLIP) Lab, UMCP

    In the project, we extracted a list of relevant properties of languages and were trying to exploit as potential features distinguishing “schizophrenic users” from controls. The features are categorized into word-based, sentence-based, topic-based, readability-based, and non-language-based.

  • Construction of Femtocell Networks Simulation Platform

    Construction of Femtocell Networks Simulation Platform

    Beijing Key Laboratory of Network System Architecture and Convergence, BUPT

    The project is designed to build the Femtocell Simulation Platform to implement the power allocation of Macrocell Base Stations and Femtocell Base Stations. Afterwards, it compares the signal-to-noise ratio among several power allocation algorithms, such as Water Filling algorithm, Average Power Allocation algorithm and so on.

  • Android App: 'Smith'

    Android App: 'Smith'

    School of Information and Communication Engineering, BUPT

    Smith chart is a graphical aid designed to solve problems with transmission lines and matching circuits. Applying the Smith chart, the project aims to develop an Android App which could do some basic electromagnetic calculations based on user input, such as computing reflection coefficients, voltage standing wave ratio and so on.

Website Development
