More and more people search online in a language that is not their native language due to the limited availability of content in underrepresented languages [1]. Most such users search in English as a second language. Very few researchers studied the challenges second language searchers face, even though searching in a foreign language and language proficiency and skills constitute an essential part of the context of searching, which can in return impact the search process and outcome. This exploratory study examines differences in first and second language web searching. Query reformulations from 14 participants who searched in English (first language) and Spanish (second language) and 17 participants who searched in Hungarian (first language) and English (second language) are analyzed and compared. Preliminary results show that searching in a foreign language requires significantly longer time, more query reformulations, and more websites viewed. User feedback also indicates that the search strategy that our participants successfully use in their first language is often much less efficient in their second language.

Despite the increasing popularity of eye tracking technique, measurement of changes in pupil diameter has received considerably less attention.However, for over two millennia it is unambiguous, by studies of acclaimed researchers (Eckhard Hess, Michel Pierre Janisse or Lowenstein and Loewenfeld) that cognitive and emotional brain activities are in connection with pupil size changes. The area, evolved by their profound and comprehensive research is referred as pupillometry.Current review describes a potential application of pupillometry in web-usability research by applying ASL Mobile Eye device.
