Measuring passers-by engagement with AmPost: a printed interactive audio poster

This paper presents AmPost, a prototype of an interactive audio poster, which integrates ink-jet printed sonic and tactile elements along with textual and graphical information. This enables users to directly interact and engage with the poster. To achieve a seamless paper-based interactive poster that includes printed interactive elements, we implement a printed speaker and audio feedback system directly into the paper-based medium, which plays a short tune when someone walks by. Engaging passers-by with this new interface becomes a challenge as posters, in general, are non-interactive. This paper also presents an initial empirical evaluation of AmPost that captures and analyses the frequency and length of user engagement, and evaluates whether user engagement improves with the integration of interactive features, in comparison to the traditional non-interactive poster. This study facilitates in building the generic approach to measure engagement that applies to any kind of posters.

Providing persuasive feedback through interactive posters to motivate energy-saving behaviours

The behaviour of building occupants can have a significant impact on in-use energy performance. In these pilot studies, based on the Elaboration Likelihood Model, interactivity was incorporated in the design of behavioural interventions to assess its effectiveness in promoting energy-saving behaviours. An interactive poster and an interactive prompt were designed to ‘nudge’ occupants’ behaviours towards energy-saving. The poster was installed in an office building and was intended to encourage occupants to save energy by taking the stairs, rather than the lifts, by providing them with cumulative metaphorical feedback. The prompt was installed in student halls of residence and intended to act as a reminder to the occupants to turn the lights off by providing them with an immediate playful reward. The results showed that interactivity can ‘nudge’ occupants’ behaviours when it is combined with a clear message/feedback. The results also suggest that simple immediate feedback can be effective in encouraging energy-efficient behaviours.

A Praça André de Albuquerque, Natal/RN, na visão de seus frequentadores

The study offers a global and interpretative view of the person-environment inter-action at André de Albuquerque Plaza, in Natal, RN, according to a descriptive-exploratory approach that aimed at learning about the space converted into place, as it is perceived and experienced by users, who attribute meaning to it. The main objective was to critically analyze the relationship person-plaza, based on data collected about users perception, utilization and ascribed meaning. I have employed an Environmental Psychology multi-method approach, including informal observations, interactive poster session, videotaping and interviews. The results indicated that the plaza, besides being a passage point, is also a spot of urban convergence for several groups, particularly taxi drivers, flanelinhas, skate boarders and students. In regard to the perception of the place, an overall positive evaluation of the plaza was verified, since people perceive selectively what interests them. In terms of usage, different groups of users presented diverse patterns of utilization, also observed in the attributed meanings. The plaza is a work place for taxi drivers and flanelinhas and a sports arena for the skate boarders, with a practical meaning for both groups. For students and other users it is a place for meeting and leisure, revealing a stronger affective quality, responsible for feelings of well being, tranquility and relaxation. The data so obtained could contribute for future government projects of intervention in those spaces, aiming at its preservation as an open spot among the concrete of city buildings, offering better quality of life, not only for today, but also for future generations

The interactive PRP for diversifying document rankings

The assumptions underlying the Probability Ranking Principle (PRP) have led to a number of alternative approaches that cater or compensate for the PRP's limitations. In this poster we focus on the Interactive PRP (iPRP), which rejects the assumption of independence between documents made by the PRP. Although the theoretical framework of the iPRP is appealing, no instantiation has been proposed and investigated. In this poster, we propose a possible instantiation of the principle, performing the first empirical comparison of the iPRP against the PRP. For document diversification, our results show that the iPRP is significantly better than the PRP, and comparable to or better than other methods such as Modern Portfolio Theory.

Zombies on the road: A holistic design approach to balancing gamification and safe driving [poster]

This paper explores novel driving experiences that make use of gamification and augmented reality in the car. We discuss our design considerations, which are grounded in road safety psychology and video game design theory. We aim to address the tension between safe driving practices and player engagement. Specifically, we propose a holistic, iterative thinking process inspired by game design cognition and share our insights generated through the application of this process. We present preliminary game concepts that blend digital components with physical elements from the driving environment. We further highlight how this design process helped us to iteratively evolve these concepts towards being safer while maintaining fun. These insights and game design cognition itself will be useful to the AutomotiveUI community investigating similar novel driving experiences.

Interactive Diffraction from Biological Nanostructures

We describe a technique for interactive rendering of diffraction effects produced by biological nanostructures such as snake skin surface gratings. Our approach uses imagery from atomic force microscopy that accurately captures the nanostructures responsible for structural coloration, that is, coloration due to wave interference, in a variety of animals. We develop a rendering technique that constructs bidirectional reflection distribution functions (BRDFs) directly from the measured data and leverages precomputation to achieve interactive performance. We demonstrate results of our approach using various shapes of the surface grating nanostructures. Finally, we evaluate the accuracy of our precomputation-based technique and compare to a reference BRDF construction technique.
