AI*HCI 2013: International Workshop on Intelligent User Interfaces
No full textAbstract. The AI*HCI workshop attempts to provide some answers on how AI can be used in the context of HCI research community. Adaptation, personalization and user modeling have been the recurrent themes among the accepted papers. These themes have been investigated and applied to several domains such as tourism, museum visits, information presentation and virtual environment adaptation.This first edition of the workshop has eight accepted papers
Motivating People in Smart Environments.
No full textIn this paper we discuss the possibility to extend PORTIA, a persuasion system currently applied in human-agent dialogs, to support ambient persuasion. We have identified a fitness center as an appropriate smart environment in which ambient persuasion strategies can be applied. According to the Ubiquitous Computing vision, in the fitness center the user is surrounded by several connected devices that cooperate in the persuasion process, each of them with the most appropriate strategy, mode of persuasion, style of communication and ability of exploiting the kairos principle. To this aim we propose a multi-agent system able to support this distributed and intelligent approach to persuasion that allows to follow the user during the gradual change from the initial attitude to sustain of long term behaviours
Evaluating natural interaction with a shop window
No full textThis paper ∗ describes the evaluation of two interaction modalities for Active Fashion, the first prototype of system designed for providing interactively information about dresses shown on mannequins in a shop window. Using the system the user may look at available sizes, colors, price and similar products. Due to the nature of such a system, the interaction must be touch-less and natural. The developed solutions use Microsoft Kinect 2 as a device. The first modality is based on gestures while the second one is based on gaze pointing. Evaluation results show that even if the interaction did not result completely satisfying from the control point of view, users prefer the gaze-based approach and felt positively engaged during the interaction
Facial expression recognition from nao robot within a memory training program for individuals with mild cognitive impairment
No full textMild Cognitive Impairment refers to a borderline state between healthy aging and dementia. Memory-training program plays a crucial role in the reduction of the possible conversion in dementia and a robot mediated memory training is useful to overcome limits of traditional programs. The present study addresses the effectiveness of a system in automatically recognize facial expression from video recorded sessions of a robot mediated memory training lasted 2 months involving 21 patients. The system is able to recognize facial expressions from group sessions handling partially occluded faces. Findings showed that in all participants the system is able to recognize facial expressions
Locate your soundscape: interacting with the acoustic environment
No full textAlthough overshadowed by visual information, sound plays a central role in how people perceive an environment. The effect of a landscape is enriched by its soundscape, that is, the stratification of all the acoustic sources that, often unconsciously, are heard. This paper presents a framework for archiving, browsing, and accessing soundscapes, either remotely or on-site. The framework is based on two main components: a web-based interface to upload and search the recordings of an acoustic environment, enriched by in- formation about geolocation, timing, and context of the recording; and a mobile app to browse and listen to the recordings, using an interactive map or GPS information. To populate the archive, we launched two crowdsourcing initiatives. An initial experiment examined the city of Padua’s soundscape through the participation of a group of undergraduate students. A broader experiment, which was proposed to all people in Italy, aimed at tracking how the nationwide COVID-19 lockdown was dramatically changing the soundscape of the entire country
