Wang, Heng is an associate professor in the Department of Computer Science and technology, School of EECS. She obtained her B.Sc. and M.Sc from Peking University in 1982, 1985, and M.Sc from Free University of Brussels in 1987, and Ph.D from Cambridge University in 1991 respectively. Before joining as a faculty at Peking University, her researches in Cambridge was funded by grants from UK ORS scholarship, Cambridge Overseas Trust Bursary, University of Cambridge, BCCI scholarship. She also participated in UK projects funded by EU grants, Cambridge University Newton Trust grant, UK NERC grants. Her research interests include human computer interaction, computer graphics, image processing.

Dr Wang has published many research papers, and most of them published in international and Chinese conferences and journals, a few examples are as following: technical report of Computer Laboratory, University of Cambridge; Associative Processing and Processors, book by IEEE Computer Science Press; Asia Pacific Conf.on CHI; International conference on Human-Computer Interaction; International conference on Human computer interaction with mobile devices & services; ACM SIGGRAPH/ Eurographics Symposium on Computer Animation etc.  She was a co-author of a text book on human computer interaction and was a member of Chinese HCI conference organizing committee and reviewing committee. She was also a NSFC grant reviewer and several Chinese journals' reviewer, and a member of ACM SIGCHI China chapter. She holds about ten national patents.

Dr Wang has been the principle researcher or a participant in about ten research projects including NSFC, 973 programs, 863 project, Royal Society-NSFC China-UK joint projects, etc. Her research achievements are summarized as follows:

Natural and harmonic human computer interaction: One major research topic in HCI field is to make the human computer interaction system support simple or more efficient interaction including speech and gesture for multimodal interaction. She and her students experimented with multimodal input with speech and touch, for applications with such as spatial objects, images, interaction histories, and proposed some new methods of data representation, retrieval and indexing structures to facilitate the organization of different types of interaction data, to efficiently support the query processing and content aware applications. 

Context aware computing: Context is a group of states, variables or parameters monitored automatically by computer programs. They can influence behaviors or the interface of an APP, or call for attentions of users to do such changes. The features of information context include computing environment such as network and server status; physical environment such as location, time light, noise etc; as well as users, for example his habit, intension, preference and so on. The researches focused on developing user models, and the mobile tour guide and other APPs were developed to incorporate those models and contexts. Some studies analysis user's preferences as the main goals for adaptation.

Mobile and ubiquitous computing: While computing devices became smaller and lighter, the new trend in interface designs is the invisible interface.  Such interface demands more intelligence on computing so intelligent recommendation techniques were developed based on user interaction behaviors.
