    National audienceCe travail cherche Ă  comprendre pourquoi les performances d'un analyseur morpho-syntaxiques chutent fortement lorsque celui-ci est utilisĂ© sur des donnĂ©es hors domaine. Nous montrons Ă  l'aide d'une expĂ©rience jouet que ce comportement peut ĂȘtre dĂ» Ă  un phĂ©nomĂšne de masquage des carac- tĂ©ristiques lexicalisĂ©es par les caractĂ©ristiques non lexicalisĂ©es. Nous proposons plusieurs modĂšles essayant de rĂ©duire cet effet

    Custom-made Tangible Interfaces with TouchTokens

    International audienceTouchTokens were introduced recently as a means to design low-cost tangible interfaces. The technique consists in recognizing multi-touch patterns associated with specific tokens, and works on any touch-sensitive surface, with passive tokens that can be made out of any material. TouchTokens have so far been limited to a few basic geometrical shapes only, which puts a significant practical limit to how tailored token sets can be. In this article, we introduce TouchTokenBuilder and TouchTokenTracker that, taken together, aim at facilitating the development of tailor-made tangible interfaces. TouchTokenBuilder is an application that assists interface designers in creating token sets using a simple direct-manipulation interface. TouchTokenTracker is a library that enables tracking the tokens' full geometry. We report on experiments with those tools, showing the strengths and limitations of tangible interfaces with passive tokens
