How to pronounce my names? NILAVRA BHATTACHARYA (Voice Courtesy: Google Translate)
I study how people find, evaluate, and consume information online, and how people’s information behaviour relates to their knowledge acquisition. This interdisciplinary research direction is known as Searching as Learning (SAL), and spans Human-Computer Interaction (HCI), Interactive Information Retrieval (IIR), and Neuro-Information Science, among others.
I use eye-tracking, EEG, and GSR (which fall under the umbrella of Neuro-Physiological methods) to observe people’s behaviour as they interact with online information. These bio-signals help us to understand, model, and predict various aspects of human information-behaviour, such as relevance-judgement, knowledge-gain, and mental workload. My broader vision is to use these bio-signals as real-time, implicit-feedback mechanisms for next-generation interactive computing systems.
