Previous Projects

TeleRobot
I did this intern project at FXPAL ( Fuji-Xerox Palo Alto Lab ) during summer 2003. The goal is to use a mobile robot to help
people work at places where they don't, won't or can't be present physically. At local site, users can use joystick to drive the robot around in a remote environment, "see" and "hear" the remote scenes, and send control commands to the robot to physically manipulate objects or electronically control devices. Furthermore,a software framework is designed to train the robot to learn
people's operation patterns by collecting multi-modality sensor readings, and automate these tasks by finding the most possible "action" in response to current input data. This project is a natural extension of the following "Shared Interactive Video", in that the cameras are installed on a mobile platform, resulting in the intended targets have to be recognized in real-time instead of pre-gestered.

Shared Interactive Video
Another intern project I did at FXPAL in summer 2002. With the system, multiple users can interact with remote devices via mouse
gestures in a window of live video mcaptured at the remote site. For example, an authorized participant may drag a presentation file from a desktop to a remote presentation screen seen in the video window, causing that presentation to be remotely displayed. The basic idea is to pre-register the controled devices in the live video, assuming the devices do not move frequently, and send mouse-gesture-based commands to the "daemon server" for the the intended target, which in turn actually manipulate the devices.

TrafficView
It is an interesting application of mobile networked devices in automobiles. In this project the vehicles were equipped with a iPAQ PDA with wireless network connection to compose of a wireless Mobile Ad Hoc Network. So that they can exchange information such as location, speed, direction, which can present a dynamic real-time traffic view to drivers. The challenges lie in the limited wireless bandwith and large amount of real-time data, for which we designed several semantic-based data aggregation algorithms.

Adaptive Multimedia Transport
Along with the emerging various computing devices and network connections, come more and more severe heterogeneity of computer capability, network bandwidth and latency. Unfortunately, few of on-line multimedia servers can automatically and timely adjust the media quality according to the client device and network condition. This project is one of the efforts to fulfill the goal. The key is taking processing time as a kind of "resource" which is allocated to different multimedia files embeded in a web page, and applying appropriate transformation to the files in the given time, so that the most information can be sent to clients under given condition.
