Human-Centered Computing Course Project Reports Monday, Dec 11th, in 405 Soda: 10:00am Guochun Liao In this project, I designed a scheme to analyze the personality and emotional content for web pages. I implemented a web-based application to evaluate personality and emotion of some web pages based on their text content. I also analyzed the usage of color and image to study the correlation between verbal cues and non-verbal cues (color, image, etc.) 10:30am Nicolas Ducheneaut Email has become the main conduit for coordination and collaboration in organizations. It is now the source of many different office tasks, serving as the place in which work is received and delegated. This paper is concerned with the nature of the work processes that are being managed in email, and the extent to which these processes could be modeled and supported by software. Numerous attempts have been made in this direction, the most famous of which may be The Coordinator (Winograd and Flores, 1986), an application of Speech-Act Theory (Austin, 1962) to IT design. Drawing on the results of two months of fieldwork conducted in three companies, I will illustrate the shortcomings of such an approach, and highlight the contingent and dynamic nature of the work processes managed in email. The approach is original in that it considers not only the content, but also the structure of email exchanges. This leads me to propose a re-conception of the kind of tools that should be designed to support email interactions in the workplace. 11:00am Tom Duan Inventing the Future Where and How Far Should Ubiquitous Computing Go "The best way to predict future is to invent it." -- Alan Kay This paper identified some of the issues, both technological and social, that are related to Ubiquitous Computing and proposed possible solutions. It argued that computers are fundamentally different from those influential innovations in human history, such as literacy and electricity, which changed our lives dramatically and are serving us ubiquitously and invisibly. These differences may make the full adoption of Mark Weiser’s vision of ubiquitous computing in our daily life not desirable. However, it agreed that ubicomp still remains extremely promising, especially in some special tasks such as space traveling, and will certainly dominate computing in the future. 11:30am Anoop Sinha I will discuss the usability evaluation of MultiPoint, a multimodal user interface for building presentations, with particular focus on participants use of speech commands. I will propose the new concept of Computer Speech Acts, a categorization of speech input commands, and relate it to traditional Speech Act Theory. 1:00pm Dan Glaser I have videotaped designers at their workplace to provide a fine-grained analysis of what they are actually doing. From this I hope to better define the role of simulation tools, identify metaphors that enable people to solve their problems, and mock up a new interface for them. 1:30pm Andrew Hill Title: Identifying Voice Subject: Determining if a speakers voice can be identified using latent semantic analysis(LSA). 2:00pm Shankar Sitarama Application of the Speech Act theory in the analysis of the classroom interactions of a business case-study discussion. Case-study method of instruction is an essential skill building exercise for the engineers / managers in their curriculum and relies on the collaborative learning that takes place in the student through the discussions on the case. Students get an insight into the decision-making process, the factors and parameters involved and the implications of the decisions through such real life cases from organizations. This learning takes place collaboratively through a meaningful discussion among peers mediated effectively by the instructor. The utterances by the students and instructor are key to the learning process and the learning process, which is essentially collaborative in nature, is embedded in the discussions. An analysis of these utterances by the students and the instructor and their intentions (locutionary and illocutionary aspects of their speech acts) provides us with valuable insights into the learning process. An attempt is made in this project to apply the Speech act theory to the utterances of the students and instructors in one such discussion of a case-study and an analysis performed. 2:30pm Matthew Kam Livenotes: a system for live, collaborative, small-group note-taking. Small group learning is a proven method for enhancing student attention, participation and understanding. Livenotes allows groups of students to work collaboratively in a conventional classroom. It is a peer-to-peer Java program which runs on inexpensive pen computers (Clios). 3:00pm Shuang Song Title: Identifying User Information Needs in SMETE Digital Library Identifying user needs and providing an efficient and effective information retrieval to meet these needs is a difficult challenge. This project aims at learning user information need by Latent Semantic Analysis. The experiment was conducted in SMETE library ( a digital library for Science, Mathematics, Engineering, and Technology Education).
