Robust and Decoupled Position and Stiffness Control for Electrically-Driven Articulated Soft Robots

2022

The control of articulated soft robots, i.e. robots with flexible joints and rigid links, presents a challenge due to their in- trinsic elastic elements and nonlinear force-deflection dependency. This letter first proposes a discrete-time delayed unknown input- state observer based on a nominal robot model that reconstructs the total torque disturbance vector, resulting from the imperfect knowledge of the elastic torque characteristic, external torques, and other model uncertainties. Then, it introduces a robust controller, that actively compensates for the estimated uncertainty and allows bounded stability for the tracking of independent link position and joint stiffness reference signals.…

Shared online spreadsheets and hidden profiles: Technological effects on dyad decision strategy

2012

We report a study in which dyads use Instant Messaging to agree a preference among a set of three apartments. The information given to participants is partially overlapping, and contains a ''hidden profile'' (HP), such that a single apartment emerges as the best according to an unweighted sum of feature values only if dyad members pool information that is presented to only one of them. When dyads were additionally provided with a shared online spreadsheet, their decision strategy was more likely to be compensatory and relatively exhaustive, even if the distribution of importance among the cues in which the apartments vary meant that a ''fast and frugal'' heuristic such as take-the-best woul…

Body Image and Virtual Reality in Eating Disorders: Is Exposure to Virtual Reality More Effective than the Classical Body Image Treatment?

2009

Body image (BI) disturbances are considered to be central in eating disorders (ED) psychopathology. There are few studies focused on the treatment of BI disturbances in ED, and most of them have used "traditional methods." The purpose of the present study was to probe the effectiveness of one specific component in the assessment and treatment of BI in ED by means of virtual reality (VR). Two treatment conditions were applied: (a) The Standard Body Image Treatment Condition (SBIT) and (b) the VR Condition. Thirteen eating disordered patients were randomly assigned to one of those conditions. No differences between both conditions were found in general ED measures, but patients treated in the…

International Perspectives on the Pedagogically Innovative Uses of Technology

2005

The children of today grow up having information and communication technologies (ICTs) as essential and natural parts of their daily life. As they grow, they are expected to become active and self-directed members in their own local communities and also in the information society at large. Technology creates versatile possibilities for the acquisition and creation of information, for self-expression, and for communication and interaction with other people locally, nationally, and worldwide. Active participation in the information society presumes novel knowledge, skills, and work approaches from children and teachers alike.

Getting Connected

2009

The large scale deployment of mobile applications inevitably impacts upon our culture as a whole and affects more intimately our daily lives. Not all of these effects are desirable. In a market economy, ethical issues are not the most important drivers in the development of technology. In this article, we ask whether the mobile human-computer interaction community could take an active role in discussing ethical issues. In so doing we could focus our attention on developing technology for ‘human beings’ rather than fine tuning our emerging gadgets.

EVE Online is not for everyone : Exceptionalism in online gaming cultures

2019

EVE Online is a space-themed massively multiplayer online game that has developed a reputation for being difficult and unwelcoming to new players. In this article, I explore how an emphasis on exceptionalism is present throughout discussions about EVE by its developer, the enthusiast gaming press, and survey responses of current players (N = 647). Taken together, information from these sources reinforces a public perception that EVE is a game that is of interest only to a very specific kind of player. In turn, these findings add further evidence to the long-argued position of feminist game scholars: Not all gaming communities are open to all players. Rather, who plays, what they play, when …

TBSSvis: Visual Analytics for Temporal Blind Source Separation

2020

Temporal Blind Source Separation (TBSS) is used to obtain the true underlying processes from noisy temporal multivariate data, such as electrocardiograms. TBSS has similarities to Principal Component Analysis (PCA) as it separates the input data into univariate components and is applicable to suitable datasets from various domains, such as medicine, finance, or civil engineering. Despite TBSS’s broad applicability, the involved tasks are not well supported in current tools, which offer only text-based interactions and single static images. Analysts are limited in analyzing and comparing obtained results, which consist of diverse data such as matrices and sets of time series. Additionally, p…

The diffusion and use of information and communication technologies and the city from 1996 to 2009

2013

The aim of this paper is to investigate whether the diffusion and the use of information and communication technologies (ICTs) are associated with the size of the place of residence where people live. The article explores how the relationship between ICTs and place of residence changed between 1996 and 2009. The study presents data from two consecutive telephone surveys collected from Italy, France, Germany, the United Kingdom and Spain. Results show an unexpected role of the relatively rural areas as attractor of new technologies. Although the largest cities have remained the locus of telecommunications on the whole, the relationship between ICTs and the place of abode has changed consider…
