Abstract. Interaction experiences with public art installations are becoming ubiquitous recently, however, interaction is usually unidirectional and the actual experience not very rich. This work reports on an interactive public art installation aiming at increasing the level of social connectedness among visitors, and the results of evaluating the attractiveness of the installation. By connecting visitors and computers physiologically, the installation has clear impact on social interaction and it also shows the attractiveness to people from aspects such as creativity, novelty, inviting and motivating. In this work we also found that the AttrakDiff instrument to be useful and convenient in evaluating the attractiveness of public art installations.

The use, the language and the implications of the material itself are different from it being applied as a carrier for public digital arts. These new media types of public digital arts are in need of new carriers and new form languages for its progress and prosperity in the age of the new technologies, from traditional ones with static forms to new ones with dynamic and interactive forms [1]. Public interactive art installations are effective in addressing and engaging multiple people, and displays and projections are often used for these installations as output devices. While the use for advertisements, entertainment and promotion is quite farspread, the usual modus operandi of a single projection is to engage people as a single person in a 1:1 message. One of the drawbacks of this kind of installation is the limited interaction space for people "using" a public projection: messages are mostly unidirectional and there is a little that a person can actually do to be engaged in a richer interaction than consuming a simple information broadcast.This work reports on the research aiming at using public art installations to address multiple (previously unconnected) people at the same time, increasing the level of social connectedness among them, and finally evaluating the attractiveness of the installation. The main challenge is to establish the public installation as a social actor -a socially acceptable participant in a social multi-user setting, in which the culture
