My primary research area is building and evaluating various privacy-related interaction techniques for social mobile software systems to better support end-users in maintaining their personal privacy in terms of how to collect and share their context data as well as how to keep users aware of how their context data has been shared with others .

Carnegie Mellon University (CMU), Human-Computer Interaction Institute (HCII) |
Description: |
This project is focused on capturing end-user privacy policies for disclosing contextual information within an Instant Messaging (IM) client. Our goal is to (1) develop novel user interfaces that effectively provide feedback and control over a user's privacy settings, and (2) conduct field studies of these techniques.

Description: |
inTouch is a mobile messaging platform that provides group-based communities (such as families, research work groups, carpools, etc) a better way to coordinate tasks, maintain a sense of shared awareness, and to generally keep in touch with fellow group members. inTouch aims to better address communication breakdowns that typically occur in short-term planning and coordination.

Description: |
Hitchhiking is a way of building a class of location-based services in a privacy-sensitive manner. Bustle is an example Hitchhiking application that can answer questions like "How busy is it at the cafe?" and "How long are the lines at the airport?" Bustle works by counting the number of wireless devices in an area and using that count to estimate the number of people.

Carnegie Mellon University (CMU), Human-Computer Interaction Institute (HCII) |
Description: |
inTune is a contextually based, self awareness application that allows users to be "in tune" with the contextual status of their social network. Measuring communication patterns between the users and other people, inTune infers a level of connectedness. Through this self-awareness, inTune hopes to change users' behavior in order to perserve and maintain a healthier social network.

| Affliation: |
Intel Research Seattle (IRS) |
Description: |
Memory Karaoke is a location-based, mobile phone application inspired by current memory therapies that aims to increase a person's usage of their episodic memory through storytelling. This is done by stimulating a person’s episodic memory as they relive, reminiscence, and retell stories about their past events while observing past contextual cues captured by the mobile device in a privacy-sensitive manner.

Carnegie Mellon University (CMU), Human-Computer Interaction Institute (HCII) |
Description: |
The eWatch prototype senses user activities based on accelometer, temperature, light, and micrphone sensors. The accelerometers and microphone provide inputs to a model of interruptibility. Depending on a message's importance and the user's interruptibilty, different vibration and visual notification patterns are sent to the user. The eWatch is transparently integrated into the user's environment, and communicates via Bluetooth.

Princeton University (PU), Department of Electrical Engineering (ELE) |
Description: |
ZebraNet is an inter-disciplinary project between Biology & Computer Science. On the computer systems side, ZebraNet is studying power-aware, position-aware computing & communication systems. Namely, the goals are to develop, evaluate, implement, and test systems that integrate computing, wireless communication, and non-volatile storage along with global positioning systems (GPS) and other sensors. On the biology side, the goal is to use systems to perform novel studies of animal migrations and inter-species interactions.<-->

MEI: Mandarin-English Information (2000-2001)
| Links: |
MEI, NSF Workshop 2000 |
| Affliation: |
Johns Hopkins University (JHU), Center for Language and Speech Processing (CLSP) |
Description: |
Mandarin-English Information (MEI) is a system whereby English speakers can find audio broadcasts in Mandarin Chinese relevant to their interests, without knowing Chinese. MEI uses written queries to search spoken documents (cross-media) between English and Mandarin Chinese (cross-language). Our research focus is on the integration of speech recognition and machine translation technologies in the context of translingual speech retrieval.
We plan to work on the problems of: (i) indexing Mandarin Chinese audio with word and subword unites, (ii) translating variable-size units for cross-language information retrieval, and (iii) devising effective retrieval strategies for English text queries and Mandrin Chinese news audio. -->
