A BCI Teleoperated Museum Robotic Guide
2009
Brain Computer Interface is a system that offers also a support to the patients with neuromuscular diseases as Amyotrophic Lateral Sclerosis. In this paper are presented some works with the aim to integrate brain computer interfaces and mobile robots. The two aim of this project are: (i) to test an improved BCI experience through the help of a physical robot, so that brain signals are stronger stimulate. (ii) to use a remote robot controlled by a highly paralyzed patient via a BCI through a friendly Graphic User. Some preliminary experiments are presented in this paper about one of the possible application: a robotic museum guide (PeopleBot and Pioneer3 robot), that can transmit remote visu…
Designing Touchless Gestural Interactions for Public Displays In-the-Wild
2015
Public displays, typically equipped with touchscreens, are used for interactions in public spaces, such as streets or fairs. Currently low-cost visual sensing technologies, such as Kinect-like devices and high quality cameras, allow to easily implement touchless interfaces. Nevertheless, the arising interactions have not yet been fully investigated for public displays in-the-wild (i.e. in appropriate social contexts where public displays are typically deployed). Different audiences, cultures and social settings strongly affect users and their interactions. Besides gestures for public displays must be guessable to be easy to use for a wide audience. Issues like these could be solved with use…
Designing for Exploratory Search on Touch Devices
2015
Exploratory search confront users with challenges in expressing search intents as the current search interfaces require investigating result listings to identify search directions, iterative typing, and reformulating queries. We present the design of Exploration Wall, a touch-based search user interface that allows incremental exploration and sense-making of large information spaces by combining entity search, flexible use of result entities as query parameters, and spatial configuration of search streams that are visualized for interaction. Entities can be flexibly reused to modify and create new search streams, and manipulated to inspect their relationships with other entities. Data compr…
Through Different Eyes. Feminine Science and Literature in Early Modern Culture
2016
The question of a dominant model of vision will be at stake in this essay, which will try to provoke other questions on the ways in which non-dominant models of vision have tried to spread out in a particularly revolutionary and dramatic period. This century is the 17th and the non-dominant model of vision is that of the female gaze. Particularly the works of three English writers – Margaret Cavendish, Aphra Behn, Eliza Haywood – and their commitment with the matter of gaze will be analysed.
La Sicilia negli Orsi di Dino Buzzati e Lorenzo Mattotti
2022
Nella fiaba illustrata di Dino Buzzati La famosa invasione degli orsi in Sicilia (1945) e nella sua trasposizione filmica ad opera di Lorenzo Mattotti (2019) l’ambientazione siciliana è determinante. In entrambi i casi la Sicilia è un’isola con un grande vulcano – trasfigurata in un ambiente fantastico o riscritta secondo alcuni stereotipi – che i due autori utilizzano con accezioni diverse nella costituzione dell’ecosistema delle loro narrazioni. Soltanto attraverso una comparazione tra le due opere sarà possibile distinguere la rappresentazione delle due Sicilie che vengono raccontate con un intervallo di circa settanta anni. Se non si considera la storia degli Orsi soltanto una fiaba per…
Premessa a: Cultura visuale in Italia : immagini, sguardi, dispositivi
2022
Questo volume raccoglie le riflessioni maturate durante il convegno internazionale “Cultura visuale in Italia. Prospettive della ricerca” svoltosi a Palermo tra il 19 e il 21 marzo 2018. Si è trattato di un incontro che ha visto la partecipazio- ne di molti dei protagonisti della ricerca italiana in quell’ambito “indisciplinato” – per usare una felice espressione di W.J.T. Mitchell – che è la cultura visuale, accademica e non, un campo di studi che ha ormai solide tradizioni internazionali e anche notevoli ricadute accademiche, come dimostra la presenza a Palermo di docenti che, pur provenendo da “altre” discipline, la comparatistica letteraria, l’estetica, la storia dell’arte, la mediologi…
Interventionist research in management accounting: promoting engagement through face-to-face dialogues
2023
PurposeThis paper explores face-to-face dialogues between practitioners and interventionist researchers in the management accounting (MA) field during real-time interactions for the development of accounting devices. It aims to shed light on whether and how these dialogues can affect the construction of meanings around the devices, thereby influencing the course of interventionist research (IVR) projects.Design/methodology/approachThis study presents a reflective analysis (both in itinere and ex-post) of an IVR project conducted by one of the authors within a healthcare organisation. It draws on a dialogical perspective to delve into the conversations between the author and the organisation…
A Configuration of 3-phase Traction Inverter Employing {SiC} Devices
2022
In the scenario of a more and more sustainable society, an increasing electrification in different fields, such as mobility and industrial applications, is foreseen in the next decades. As far as power electronics is concerned, a challenging perspective is represented by achieving higher and higher switching frequencies while maintaining high voltage and low power losses. To do that, emerging semiconductor technologies are supposed to be increasingly employed, as well as innovative topologies of connections among switching devices. Among them, the cascode configuration can notably contribute to achieve high levels of dV/dt without losing efficiency. In this paper, a 3-phase Pulse Width Modu…
Periodic time-domain modulation for the electrically tunable control of optical pulse train envelope and repetition rate multiplication
2012
An electrically tunable system for the control of optical pulse sequences is proposed and demonstrated. It is based on the use of an electrooptic modulator for periodic phase modulation followed by a dispersive device to obtain the temporal Talbot effect. The proposed configuration allows for repetition rate multiplication with different multiplication factors and with the simultaneous control of the pulse train envelope by simply changing the electrical signal driving the modulator. Simulated and experimental results for an input optical pulse train of 10 GHz are shown for different multiplication factors and envelope shapes. © 2006 IEEE.
Route diversity analyses for free-space optical wireless links within turbulent scenarios
2013
Free-Space Optical (FSO) communications link performance is highly affected when propagating through the time-spatially variable turbulent environment. In order to improve signal reception, several mitigation techniques have been proposed and analytically investigated. This paper presents experimental results for the route diversity technique evaluations for a specific case when several diversity links intersects a common turbulent area and concurrently each passing regions with different turbulence flows.
