Exploring web-mediated communication: A genre-based linguistic study for new patterns of doctor–patient interaction in online environment
2016
This paper questions the nature of the communicative event that takes place in online contexts between doctors and web-users, showing computer-mediated linguistic norms and discussing the nature of the participants’ roles. Based on an analysis of 1005 posts occurring between doctors and the users of health service websites, I analyse how doctor–patient communication is affected by the medium and how health professionals overcome issues concerning the virtual medical visit. Results suggest that (a) online medical answers offer a different service from that expected by users, as doctors cannot always fulfill patient requests, and (b) net consultations use aspects of traditional doctor–patient…
Improving Usability of Location-Based Services with User-Centric Data Querying
2004
In this paper, we describe a computational model that produces a dataset which we consider to be an appropriate response for “give me a description of my neighborhood” type of queries in location-based services Our attempt is to reflect the abstraction ability of a specific user, and in this way to maximize the usability of the service under restrictions on data volume posed by technical, economical and cognitive factors of mobile environments We also present the results of instantiating the model for a simple LBS.
Temporal and spatial analysis to personalise an agent's dynamic belief, desire, and intention profiles
2003
The paper addresses the dynamic belief, desire and intention profiles that can be made of an agent following a particular route, for example through a city. It assumes that location of an agent has effects on his beliefs desires and intentions and that the history of agent’s mobility and observed states in different locations can be used to predict his future states if the location is being permanently observed. A formal spatial route language is introduced. Formal relationships between the intentional notions, and the spatial behaviour of an agent are defined. As an application an information agent architecture for reasoning about the intentions of the customers of a mobile location-based …
A Multimodal Guide for the Augmented Campus
2007
The use of Personal Digital Assistants (PDAs) with ad-hoc built-in information retrieval and auto-localization functionalities can help people navigating an environment in a more natural manner compared to traditional audio/visual pre-recorded guides. In this work we propose and discuss a user-friendly, multi-modal guide system for pervasive context-aware service provision within augmented environments. The proposed system is adaptable to the user needs of mobility within a given environment; it is usable on different mobile devices and in particular on PDAs, which are used as advanced adaptive HEI (human-environment interaction) interfaces. An information retrieval service is provided that…
A Multi-channel Communication Framework
2013
We present a modular framework for a business-to-customer communication service integrating several communication channels. Using such a service it is possible to find hidden relationships between messages and thus collect more customer-related data. The framework core is a message-conversion engine capable of converting channel-independent abstract messages into concrete messages and vice-versa. The conversion process is context-dependent. The context consists of formally described communication channel characteristics and user preferences. The framework is based on semantic technologies due to a balance between their expressive power, reasoning properties, and existence of production-qual…
Interaction Mechanism of Humans in a Cyber-Physical Environment
2015
The research initiative “Industrie 4.0” (I4.0) of the high-tech strategy announced by the German government targets the deployment of a cyber-physical system (CPS) in production and logistics. Such CPS-based environments are characterized by an increasing number of heterogeneous intelligent autonomous and communicating artifacts tightly integrated with humans. Thus, the human’s role will become a composite factor (“man-in-the-mesh”) for this future CPS environment, playing more than just a simple role inside the control loop. This paper investigates the need of a robust communication between CPS and humans, which includes a clear semantic of the exchanged information. For this purpose, a me…
GUI Usability in Medical Imaging
2009
The diffusion of computer technologies in everyday life has involved the birth of standard methodologies to control their development. Indeed, the purpose of standardization procedures consists of providing rules aimed to control technologies leaving no space for empirical improvisations. In general, medical software manufacturers provide their applications with Graphic User Interfaces (GUI) that are not compliant with any clear and standard usability criterion. The only guideline is the creation of GUIs inherited from the ones adopted on medical consoles because physicians use them routinely. This paper addresses this issue: medical software interfaces should be designed trying to overcome…
EntityBot: Supporting Everyday Digital Tasks with Entity Recommendations
2021
Everyday digital tasks can highly benefit from systems that recommend the right information to use at the right time. However, existing solutions typically support only specific applications and tasks. In this demo, we showcase EntityBot, a system that captures context across application boundaries and recommends information entities related to the current task. The user’s digital activity is continuously monitored by capturing all content on the computer screen using optical character recognition. This includes all applications and services being used and specific to individuals’ computer usages such as instant messaging, emailing, web browsing, and word processing. A linear model is then …
Accessing and selecting menu items by in-air touch
2019
Is it possible to realize a non-visual, purely tactile version of an icon-based menu? Driven by such question, a hierarchical tactile dock was designed for an array of ultrasound emitters. The icons were conceived as spatio-temporal variable-speed sequences of tactile stimulation points, that are passively perceived as trajectories drawn on the palm of the hand. The recognition rate on four icons largely improved prior performance results obtained by active haptic exploration. As a result, a four-icons set can be used as the first level of a hierarchy of symbols that can be navigated by touch and gesture. The design process, based on controlled recognition experiments and exploration of dis…
A Case of Cooperative Sound Design
2016
In this design case study, protocol and linkographic analysis are applied to a task of cooperative vocal sketching, proposed in the scope of educational research activities. The understanding of the cognitive behaviors involved in sound creation is aimed at setting the ground for the development of rigorous, designerly evaluation practices tailored to sound design, all the way to the final interactive product. Relevant qualitative and quantitative information about the creative process informs the assessment and possibly improvement of sound design methods.
