Multi-Display Tabletop for Public Engagement in Urban Design
I am working on a tabletop urban design visualization which was developed and iteratively improved over five years to engage diverse audiences such as planners, designers and the public in the task of generating and testing urban planning and design options. I am investigating how to advance current visualization and interaction techniques to better help stakeholders with evaluation of alternative designs. [Paper, CSCW][Poster, GI][video]
CLIP (Collaborative Intelligent Pad)
CLIP is a prototype tool designed and implemented to facilitate collaborative sense making. The focus of this project is to assist intelligence analysts to record, schematize and share their findings and hypotheses. Utilizing peer-to-peer communication, all working instances of CLIP broadcast the latest work of an analyst to the rest of the group. Different privacy levels provides controlled sharing. CLIP supports providing awareness of common work by visually indicating common entities. [Paper GRAND 2014] [Paper VAST 2014] [Video]
CoSpaces (Collaborative Workspaces)
CoSpaces is a prototype that is designed for collaborative data analysis on a large interactive tabletop display. It enables multiple users to simultaneously work together and create statistical charts. Some main features include the ability to recored and keep track of the work by automatically saving charts, and also an embedded note taking mechanism. Tabs are used as channels for providing awareness of collaborators’ work status. Each tab provides a portal for viewing work in progress in another workspace without any interruption. Using tabs, an analyst can view a collaborator’s current work, review work history and study findings. [Paper DEXIS 2011] [Paper HICSS 2013] [Video]
Collaborative Visual Data Analysis Around Large Interactive Surfaces
To gain a deeper understanding of collaborative visual data analysis around large interactive surfaces, we designed and carried out an observational user study. Co-located teams worked on collaborative visual analytics tasks using large interactive wall and tabletop displays. Our findings reinforced the importance of record keeping as an integral activity during collaborative data analysis. In addition, we characterized notes according to their content, scope, and usage, and described how they would fit into the process of collaborative data analysis. We also suggested design guidelines for note-taking functionality for co-located collaborative visual analytics tools. [Paper InfoViS Journal 2012] [Paper VAST 2010] [Paper CoVis 2009]
Creative Pad
Creative-Pad is designed initially as a tool to help creative directors in an advertising agency to come up with new ideas to create an advertisement for their clients. These directors are often given a one-line brief describing a client product or service. For example, the sentence, “A car with more family space”, would describe a client’s new product which is a car targeted for family. The creative directors would have to design an advertisement suitable for promoting this product. They will need lots of ideas. Creative-Pad works by tapping into the internet as a rich source of information about all things. It takes in one or more keywords from the initial sentence and automatically searches the internet to retrieve any related information. It then processes the search results to extract interesting words and sentences. These words and sentences are then “beamed” in front of the creative directors to stimulate their thoughts for the new advertisement. An interface was specially designed to encourage creative thinking. [Paper ICCC 2010]
