Exploring the potential of a mobile eye tracker as an intuitive indoor pointing device: A case study in cultural heritage.

Current technology offers a variety of ways for context-aware information delivery to mobile users. The most challenging aspect, however, is to determine what the user is interested in. The user’s position is the best available hint, but if we know what the user is looking at and what his or her gazing profile is, we can narrow down the possibly relevant objects of interest. With the advent of mobile and ubiquitous computing, it is time to explore the potential of mobile eye tracking technology for natural, intelligent interactions between users and their smart environment, not only for specific tasks, but also for the more ambitious goal of integrating eye tracking into the process of inferring mobile users’ interests, for the purpose of providing them with relevant services, a research area that has received little attention so far.
