In this project, we tried to visualize the open crime data provided by Seattle government. We want to change the way these data are visualized by current popular icon-based practice. With our visualization, we hope to extract more useful information behind the data for our users: seattle citizens and police department. we designed the visualizations based on the principles and theories we learnt in class. And implemented it with d3, html, css, jQuery etc.
Because I did not have much experience in programming by the time I was in the project team, I took responsibility in the website design (making three mockups with Omnigraffle, Axure and Keynotes) & conducted the usability test (with 2 police officers and 3 UW students) & wrote the “usability test report” and “previous work and literature review” sections in our final report. All our team members took active part in the visualization design, although only two of those design ideas were finally implemented. The walkability map I sketched with adobe photoshop was one of those not implemented finally because of project-time-restriction. Our final report will be used as sample for next year’s class. And the usability test result is identified as the strongest part of the paper.
