Predicting mid-air gestural interaction with public displays based on audience behaviour

2020

Abstract Knowledge about the expected interaction duration and expected distance from which users will interact with public displays can be useful in many ways. For example, knowing upfront that a certain setup will lead to shorter interactions can nudge space owners to alter the setup. If a system can predict that incoming users will interact at a long distance for a short amount of time, it can accordingly show shorter versions of content (e.g., videos/advertisements) and employ at-a-distance interaction modalities (e.g., mid-air gestures). In this work, we propose a method to build models for predicting users’ interaction duration and distance in public display environments, focusing on …

Tuning the field trip: audio-guided tours as a replacement for 1-day excursions in human geography

2013

Educators are experiencing difficulties with 1-day field trips in human geography. Instead of teaching students how to apply theory in the field and learn to sense geography in everyday life, many excursions have degraded into tourist-like events where lecturers try to motivate rather passive students against a noisy urban backdrop. Although various (partly) student-led approaches have successfully addressed the issue, there are still a high number of tours that use a traditional, tutor-led model. The example of a series of three audio tours produced at Johannes Gutenberg-University Mainz, Germany, shows how these conventional field trips can be transformed into audio tours that help studen…

Visuo-auditory sensory substitution systems are augmented reality devices that translate a video stream into an audio stream in order to help the blind in daily tasks requiring visuo-spatial information. In this work, we present both a new mobile device and a transcoding method specifically designed to sonify moving objects. Frame differencing is used to extract spatial features from the video stream and two-dimensional spatial information is converted into audio cues using pitch, interaural time difference and interaural level difference. Using numerical methods, we attempt to reconstruct visuo-spatial information based on audio signals generated from various video stimuli. We show that de…

Using continuous user authentication to detect masqueraders

2003

Nowadays computer and network intrusions have become more common and more complicated, challenging the intrusion detection systems. Also, network traffic has been constantly increasing. As a consequence, the amount of data to be processed by an intrusion detection system has been growing, making it difficult to efficiently detect intrusions online. Proposes an approach for continuous user authentication based on the user’s behaviour, aiming at development of an efficient and portable anomaly intrusion detection system. A prototype of a host‐based intrusion detection system was built. It detects masqueraders by comparing the current user behaviour with his/her stored behavioural model. The m…

Architectures for autism

2015

Le ricerche condotte sulle malattie degenerative della "terza età", hanno visto negli ultimi anni il gruppo di studio palermitano indagare e proporre soluzioni che vanno dalla stesura di linee guida per la progettazione di Residenze Sanitarie Assistenziali (RSA), alla progettazione esecutiva di architetture residenziali, al recupero e riuso di edilizia già esistente fino alla progettazione dello spazio domestico dedicato e protetto, che oltre a fornire risposte funzionali ne ha anche esaltato il design degli elementi di arredo. A questo ambito di ricerca da circa due anni si è affiancato un nuovo settore di indagine indirizzato sempre alle "minoranze sociali". Research conducted on degenera…

Tourism Statistics for Destination Management: The Trips/Arrivals Model

2014

Simply counting the number of tourists in a destination is not as simple as one might initially think. The present work intends to formalize a conceptual model by decomposing tourism nights, trips, and average duration of visit in a given destination, in terms of quantities and parameters that only for a small part could be derived from official tourism statistics. On the other hand, most of the quantities and parameters required for determining the number of tourists in a given destination are in general unknown, and need to be (directly or indirectly) estimated. Empirical evidences resulting from a survey on incoming tourism in Sicily are provided, showing the biases affecting supply-side…

Efficient techniques for energy saving in data center networks

2018

Data centers are constructed with a huge number of network devices to support the expanding cloud based services. These devices are used to achieve the highest performance in case of full utilization of the network. However, the peak capacity of the network is rarely reached. Consequently, many devices are set into idle state and cause a huge energy waste leading to a non-proportionality between the network load and the energy consumed. In this paper, we propose a new approach to improve the efficiency of data centers in terms of energy consumption. Our approach exploits the correlation in time of the inter-node communication traffic and some topological features to maximize energy saving w…

A NEW COMPLEXITY FUNCTION FOR WORDS BASED ON PERIODICITY

2013

Motivated by the extension of the critical factorization theorem to infinite words, we study the (local) periodicity function, i.e. the function that, for any position in a word, gives the size of the shortest square centered in that position. We prove that this function characterizes any binary word up to exchange of letters. We then introduce a new complexity function for words (the periodicity complexity) that, for any position in the word, gives the average value of the periodicity function up to that position. The new complexity function is independent from the other commonly used complexity measures as, for instance, the factor complexity. Indeed, whereas any infinite word with bound…

Déjà vu experiences in healthy subjects are unrelated to laboratory tests of recollection and familiarity for word stimuli

2013

Recent neuropsychological and neuroscientific research suggests that people who experience more déjà vu display characteristic patterns in normal recognition memory. We conducted a large individual differences study (n = 206) to test these predictions using recollection and familiarity parameters recovered from a standard memory task. Participants reported déjà vu frequency and a number of its correlates, and completed a recognition memory task analogous to a Remember-Know procedure. The individual difference measures replicated an established correlation between déjà vu frequency and frequency of travel, and recognition performance showed well-established word frequency and accuracy effect…
