Tessa Lau's Research

My fundamental interest lies in the marriage of AI and human-computer interaction. I seek to use AI techniques to make computing systems easier to use. Current interfaces require users to learn to speak the language of the system in order to do their work. I believe that by incorporating ideas from knowledge representation, learning, and planning into the interface, we can create user-oriented systems that are easy to use, personalized, and adapt to best serve the needs and goals of their users.

I am primarily a systems HCI researcher. My work is oriented around creating prototypes of systems that demonstrate new ways for people to interact with computing, and evaluating their use in the field. Areas I have worked in include:

• End user programming and programming by demonstration
• Web automation, scripting, and accessibility
• Social and collaborative software: email, people tagging, social networks
• Conversational interfaces, information retrieval, information extraction
• Automated functional testing
• Applied machine learning, natural language processing

Past projects include CoCo (conversational interfaces for arbitrary web applications), CoScripter (web scripting by demonstration), and SMARTedit.
