new approaches for automated video and audio indexing, navigation, visualization,
search and retrieval and embedded them in a system for use in education,

My Role & Responsibilities
I work on the following:
- Develop and empirically test UI for inspecting large
collections of thumbnails (news video & personal photograph
- Augment the video-viewing experience to help
users find their information effectively and efficiently.
- Test UI for visualizing vast amounts of news
video (CNN, ABC, foreign video).
- Designing and running experiments to test these features.
- Port the project from VB to C# and write a large,
multimedia MDI application.
I see these as important problems. Individuals and teams are creating
more content than they can organize effectively and an urgent need exists
for tools to help humans deal with large amounts of multi-media.
Filtering (ACM-SIGIR, Spring 2004)
Two findings arise from this study: (1) a threshold for how good
content-based image filters need to be before they are useful
to users and (2) how large the set of images must be before filters
Digital Video Interfaces (ACM-MM, Fall 2004)
Traditionally, our interface performed well with expert users
so we ran studies where novices used the system. We also present
findings from appling formal usability techniques to evaluate
our digital video library interface.
Video Browsing with an Eye-Tracking Evaluation of Feature-Based
Color Bars (ACM/IEEE JCDL, Spring 2004)
This paper explains a method for leveraging the standard video
timeline widget as an interactive visualization of image features.
An eye-tracking experiment is described with results that indicate
that such a widget increases task efficiency without increasing
complexity while being easily learned by experiment participants.
Note: awaiting conference submission rejection or approval.
Information Visualizer: Assessing the Benefits of Imagery and Text
in News Video Collages (September 2002)
This paper presents a task-based evaluation measuring the effectiveness,
efficiency, and satisfaction with this particular visualization
interface for a broadcast news video corpus.
Moraveji, N., (September 2002) (Low-Res video)
For code samples, please contact me. I wrote
tens of thousands of lines of C# code, dealing with some complex programming
- an in-house image caching solution
- custom controls (enhanced sliders, thumbnails, etc.)
- DirectX 9
- optimzation of database calls
- delegates and events
- calls to native Win32 function
- proper documentation nDoc
