Extending the semiotics of embodied interaction to blended spaces.

2015

In this paper, we develop a new way of understanding interactions in blended spaces. We do this by developing ideas about embodied semiotics and then apply these ideas to the analysis of interaction in mixed-reality blended spaces (where the physical world and digital world are blended deliberately to provide new forms of interaction). We discuss how blended spaces provide a new medium within which people have experiences. The semiotic analysis reveals how blended spaces are constructed across the physical and the digital, highlighting the ontology, topology, volatility, and agency present within them. It shows how people move between the physical and digital spaces through the objects and …

DETECTING FALLS AT HOME: USER-CENTERED DESIGN OF A PERVASIVE TECHNOLOGY

2016

Falling is the main cause of domestic accidents and fatal injuries to seniors at home. In this paper, we describe the design process for a new pervasive technology (CIRDO). The aim of this technology is to detect falls (via audio and video sensors) and to alert the elderly's family or caregivers. Two complementary studies were performed. Firstly, the actual risk situations of older adults were analyzed. Secondly, social acceptance was investigated for the different homecare field stakeholders. Our results highlight the tensions among social actors towards the tool and their impacts on technology acceptance by the elderly. Also, we show a significant change in the fall process due to the dev…

Human Technology : Toward the Second Decade

2015

The inaugural issue of Human Technology: An Interdisciplinary Journal on Humans in ICT Environments was published in 2005. The 10 volumes of two to three issues comprise well over 2000 pages. Upon starting as editor in chief in January 2015, I browsed through the archives and noticed that just over 100 articles had been published in the journal. Examining these titles, it is evident that they address a wide variety of topics. Nevertheless, four broad themes emerge:  The user of technology, with such foci as user experience, user characteristics, usability, user interface, and, on a more theoretical level, cognition;  The learner in a technological environment, covering aspects such as inf…

From Technology to the Human User

2008

When thinking of users, it is possible to look at them from a variety of perspectives. One essential way of considering users within the human–technology environment involves technical concepts. In this manner, we define what users should be able to do with a particular technical system. As such, there are tasks to accomplish and goals to reach by means of some technology, and therefore specific operations must be carried out in order to reach those goals or fulfill those tasks. For example, if someone wishes to buy boots from an eShop, it is necessary to get onto the Internet, find the eShop, find the boots, load them into a virtual shopping cart, and follow the process to check out. Savvy…

Codesigning technology for a voluntary-sector organization

2019

© 2019 Khushnood Naqshbandi, Simon Hoermann, David Milne, Dorian Peters, Benjamin Davies, Sophie Potter, & Rafael A. Calvo. This paper presents an investigation into the experiences and perceptions of volunteers and community managers of an Australian voluntary-sector organization that supports young help-seeking people. The process focused specifically on the design of a chat tool, a rudimentary version of which was conceptualized and tested during a trial completed prior to this study. The process explored the motivations and experiences of these volunteers using a codesign approach, which led to the development of specific features of the chat tool that were tailored to the nature of the…

Help! Is my Chatbot Falling into the Uncanny Valley? : An Empirical Study of User Experience in Human-Chatbot Interaction

2019

Original article available at http://dx.doi.org/10.17011/ht/urn.201902201607 Advances in artificial intelligence strengthen chatbots’ ability to resemble human conversational agents. For some application areas, it may be tempting not to be transparent regarding a conversational agent’s nature as chatbot or human. However, the uncanny valley theory suggests that such lack in transparency may cause uneasy feelings in the user. In this study, we combined quantitative and qualitative methods to investigate this issue. First, we used a 2 x 2 experimental research design (n = 28) to investigate effects of lack in transparency on the perceived pleasantness of the conversation in addition to percei…

The Up-Cycle Beyond the Crime: The Productive Re-Activation of Confiscated Criminal Assets

La ricerca “The Up-Cycle Beyond the Crime: the Productive Re-Activation of Confiscated Criminal Assets” affronta il tema del reinserimento dei beni confiscati alla organizzazioni criminali in nuovi cicli di vita produttivi. La tesi è sviluppata attraverso tre parti principali. La prima parte è dedicata all’inquadramento scientifico del tema e all’apparato teorico, proponendo un regesto critico delle teorie e dell’evoluzione del concetto di riciclo della città e del territorio, con particolare attenzione alla modalità dell’up-cycle, attingendo sia alla letteratura delle scienze sociali, geografiche ed economiche sia alle pratiche relative alla riattivazione dei metabolismi territoriali. La s…

Sosiaalialan asiakastietojärjestelmissä paljon parannettavaa: käyttäjäkokemukset 2019

2020

Sosiaali- ja terveydenhuollon digitalisaatiolle on asetettu paljon odotuksia niin palveluiden laadun, saavutettavuuden kuin tehokkuuden osalta. Asiakas- ja potilastietojärjestelmiltä odotetaan paljon tavoitteiden saavuttamiseksi. Asiakastietojärjestelmät ovat laajasti käytössä sosiaalialalla, mutta niiden käyttöä työvälineenä ja niiden avulla saavutettuja hyötyjä on tutkittu ammattilaisten näkökulmasta vain vähän. Keväällä 2019 kartoitettiin ensimmäistä kertaa valtakunnallisesti sosiaalialan ammattilaisten käyttäjäkokemuksia asiakastietojärjestelmistä. Tässä artikkelissa kuvataan kyselytutkimuksen toteutus ja tulokset eniten käytettyjen tuotemerkkien osalta. Tutkimus toimii pilottina vuonna…

Multilayer Network Analysis: The Identification of Key Actors in a Sicilian Mafia Operation

2021

Recently, Social Network Analysis studies have led to an improvement and to a generalization of existing tools to networks with multiple subsystems and layers of connectivity. These kind of networks are usually called multilayer networks. Multilayer networks in which each layer shares at least one node with some other layer in the network are called multiplex networks. Being a multiplex network does not require all nodes to exist on every layer. In this paper, we built a criminal multiplex network which concerns an anti-mafia operation called “Montagna” and it is based on the examination of a pre-trial detention order issued on March 14, 2007 by the judge for preliminary investigations of t…
